Gearlab Engineer Designs a Device to Test Stress on a Paddle
By Declan J. Nowak
What is the mechanism you created?
I designed an Arduino powered force sensor that recorded the force exerted by a paddler’s hands on a paddle. An Arduino is a small lightweight microcontroller that is perfect for data recording applications because it is capable of recording information to an SD card. The device used two force sensors wired to the Arduino (shown in the images below). The force sensors were mounted on moldable plastic frames to fit around a forefinger and thumb. While the sensor would work without a frame to hold it, the force sensor delivers better results when it makes contact between two hard surfaces (paddle and frame), rather than one hard surface (the paddle) and a compressible surface (skin).
What is the premise you hope to achieve with this mechanism?
The goal of the sensor is to measure the force of water on the blade of the paddle. Initially, I tested under “ideal paddling conditions”, which would be a kayaker performing a standard Greenland stroke in calm weather/water conditions. This measurement under ideal conditions will act as a control value to compare the stress on a paddle during rougher water conditions and more strenuous strokes.
Since the blade of the paddle is submerged in the water, it experiences a distributed load from the water, which is challenging to accurately measure. The easiest way to measure this force is through force analysis, which requires identifying the forces applied by the paddler’s hands to calculate the force on the blade of the paddle. Using the sensor, I was able to determine the maximum force a paddler is likely to apply in ideal paddling conditions. With this knowledge, we can compare the results of testing a paddle in many conditions (various strokes and water conditions) to the results recorded in a controlled environment. Knowing the stress point at which a paddle will break in controlled lab tests, and what the average force of a paddle stroke is, Gearlab can ensure that every paddle will handle tough conditions and more than meet the customers’ expectations.
How did you conduct testing?
After programing and wiring the sensor, I attached the frames to my hands and placed the Arduino in a dry bag. I proceeded to paddle around a cove for several minutes while I performed different types of strokes. I used a Greenland forward paddling stroke, brace strokes, and sweep strokes to simulate the standard usage of the paddle. While I paddled, the data was recorded on an SD card. I subsequently downloaded the data onto a spreadsheet and calculated the force on the blade of the paddle for each stroke and graphed it.
What were the results of your testing?
After running the test and calculating the force on the blade of the paddle, I graphed the force to see how it changed as the paddle was used. Each data point on the graph was obtained every tenth of a second. The data shown in the chart represents about 41 seconds of paddling. The data used was the middle 41 seconds of the total 3 minutes of paddling, to exclude the initial force exerted when launching or the deceleration of force when stopping. I determined from the testing and the force analysis that the maximum force was 26.7 kg on the blade of the paddle. From separate lab tests, we already knew that the paddle could easily withstand 50 kg of force in a standard stroke. It required over 70 kg of force during a sweep stroke to break a paddle during laboratory testing. A sweep stroke generates greater stresses within the paddle than a standard paddle stroke since the force is applied at a greater distance from the paddler’s hands. This shows that the maximum force of the paddle is more than double the maximum force on the paddle under normal operating conditions.
*To simplify the graph, no data is recorded when the sensors registered a force of zero.
**While the analysis states that the units of kilograms are a force, the paddle is actually moving the mass of water. The force on the paddle will depend on how fast the paddler is accelerating. For the purposes of this experiment, I assumed that the paddler’s acceleration was the same as the acceleration due to gravity—which is significantly more than the rate a paddler would be accelerating.
How does this serve the consumer?
Gearlab can utilize these results to better serve the consumer by continuing to test their existing paddles to ensure that they will meet the consumer’s expectations. Concrete understanding of the force that a paddle can withstand will assist Gearlab in developing paddles that will withstand all paddling conditions. The idea for this project arose when Gearlab engineers realized that we didn’t know exactly how much force is applied to the paddles during various water and stroke conditions. The best way to begin testing the paddles was to utilize ideal paddling conditions to determine the baseline (“control value”) of stress exerted on a paddle in use. With this information, Gearlab can now stress test their paddles in a controlled way to make sure each paddle that is shipped out will more than meet the customers’ expectations.
How does this serve the brand and product development?
While each kayak paddle company has their own internal standards for product development, Gearlab is working toward establishing a universal standard. This new standard will allow for the consumer to compare the strength of paddles manufactured by different companies, the strength of various lengths and widths of Greenland paddles, and even compare the strength of different types of paddles (such as Euro blades versus Greenland paddles.) The first step was to create a method to calculate the stress on a paddle. The real world test using the sensor while paddling on the water validated the tests that Gearlab conducted in a controlled laboratory setting since the results were similar.
What will this mean to Gearlab as it communicates to the consumer?
This process will allow Gearlab to test their paddles in another manner before sending them to the consumer. While this has not been a problem in the past, Gearlab will have a more definitive metric to test their paddles against to ensure that each paddle manufactured performs superiorly for consumers. In addition, establishing a universal metric for paddle companies will allow Gearlab to quantify the superior strength of their paddles compared to competitors’ products.
What are different improvements and advancements that you can look forward to in additional testing?
Moving forward, the goal is to continue to refine the testing apparatus so the data is easier to analyze. One modification will be to program the Arduino to assign a time to each data point. This will allow us to sync the data to a video clip to see how the paddle reacts to different strokes. In addition, continued testing will help Gearlab confirm the maximum forces that the paddle experiences. One of the major assumptions made with this project was to test the paddle in ideal paddling conditions. This was done to eliminate other potential variables, and to make it easy to troubleshoot the sensor if anything went wrong. However, often times these paddles are used in rough water conditions with significant waves and currents. Therefore, future tests will include using the paddle in a variety of different weather conditions to calculate how the forces on the paddle change.

The U.S. Postal Service pursued a project to build and secretly test a blockchain-based mobile phone voting system before the 2020 election, experimenting with a technology that the government’s own cybersecurity agency says can’t be trusted to securely handle ballots. The system was never deployed in a live election and was abandoned in 2019, Postal Service spokesman David Partenheimer said. That was after cybersecurity researchers at the University of Colorado at Colorado Springs conducted a test of the system during a mock election and found numerous ways that it was vulnerable to hacking.

FM Dye Cycling at the Synapse: Comparing High Potassium Depolarization, Electrical and Channelrhodopsin Stimulation
- PMID: 29889207[PubMed].
FM dyes are used to study the synaptic vesicle (SV) cycle. These amphipathic probes have a hydrophilic head and hydrophobic tail, making them water-soluble with the ability to reversibly enter and exit membrane lipid bilayers. These styryl dyes are relatively non-fluorescent in aqueous medium, but insertion into the outer leaflet of the plasma membrane causes a >40X increase in fluorescence. In neuronal synapses, FM dyes are internalized during SV endocytosis, trafficked both within and between SV pools, and released with SV exocytosis, providing a powerful tool to visualize presynaptic stages of neurotransmission. A primary genetic model of glutamatergic synapse development and function is the Drosophila neuromuscular junction (NMJ), where FM dye imaging has been used extensively to quantify SV dynamics in a wide range of mutant conditions. The NMJ synaptic terminal is easily accessible, with a beautiful array of large synaptic boutons ideal for imaging applications. Here, we compare and contrast the three ways to stimulate the Drosophila NMJ to drive activity-dependent FM1-43 dye uptake/release: 1) bath application of high [K+] to depolarize neuromuscular tissues, 2) suction electrode motor nerve stimulation to depolarize the presynaptic nerve terminal, and 3) targeted transgenic expression of channelrhodopsin variants for light-stimulated, spatial control of depolarization. Each of these methods has benefits and disadvantages for the study of genetic mutation effects on the SV cycle at the Drosophila NMJ. We will discuss these advantages and disadvantages to assist the selection of the stimulation approach, together with the methodologies specific to each strategy. In addition to fluorescent imaging, FM dyes can be photoconverted to electron-dense signals visualized using transmission electron microscopy (TEM) to study SV cycle mechanisms at an ultrastructural level. We provide the comparisons of confocal and electron microscopy imaging from the different methods of Drosophila NMJ stimulation, to help guide the selection of future experimental paradigms.

Innovations needed for an aging population.
The world is facing a change in demographic situation where a diminishing part of the population shall support a growing group of elderly. In addition to this we see rising numbers of life style related diseases such as dementia and cardiovascular diseases. This situation calls for innovations. In this context we offer a non-intrusive, autonomous supervision system for elderly based on novel radar sensor technology.
This system offers monitoring of vital signs, that is respiration pattern and respiration rate. Moreover is the sensor is able to capture and alert on, motion and presence/absence of one or more persons in a room. From the caregivers point of view this means that nightly supervision of within a nursing home for example can be done more efficiently as resources are directed towards patients in need of help rather than ambulatory fixed-time visits. From the patients point of view it means that he/she can feel safe at night without being unnecessarily disturbed.
RayVS1 offers comfort and security.
AI has the potential to be a gamechanger for the eHealth market. These services need reliable data. Raytelligence aims at playing a global role in this Eco-system. With our sensors and services we can play an important role in collecting data and make decisions for the AI algorithms.
The EaZense sensor provides a high-level service to the end user. Signal processing and signal analysis is performed in the sensor itself and/or in a cloud service. Examples of such services are:
- “Patient X sleeps well with respiration rate 23 bpm”
- “Patient Y has fallen out of bed”
- “Person Z has a walking speed deviating from normal”
These services can be calculated in the sensor itself or in a cloud service. The cloud service is particularly interesting when several sensors cooperate to deliver a specific service e.g. cover an entire apartment.
All signal processing for vital sign monitoring is performed within the sensor. This means that all relevant information is sent to the caregivers IT-system for proper action e.g. alarms, alerts or pure logging. Besides of respiratory rate, sleep quality is also a specific parameters of interest.
The EaZense sensor has capability to run machine learning algorithms in the sensor it self or in a connected cloud-based service. These algorithms are used for modeling normal behavior by relying on detected trends and deviations from such. The sensor is particularly suited to monitor parameters that has been proven to be early warnings of cognitive impediment.
Our sensor enable care facilities to identify and characterize patient activities over time. By analyzing sensor data streams over a longer time perspective, caregivers can have a continuous and unubtrusive tool for measuring e.g. patients improvement after a surgery.

A new report confirms that AI is the future but it’s going to take some time for business and consumers to catch up to Investor’s expectations.
According to Forrester the overall artificial intelligence software market — despite ballooning to $37 billion by 2025 — will fall below current investor projections of $150 to $200 billion for the same time period. Within the AI software market, AI application growth will be constrained by technology vendors embedding AI functionality into existing software products with greater frequency.
A new Forrester report, “The AI Software Market Will Grow To $37 Billion Globally By 2025,” outlines key reasons for this updated AI software market outlook — which leaves out hardware and consulting services — including:
- Post-2023, AI software revenues will be less than 3% of the overall application market. AI in business apps will be the norm, prompting AI-centric and AI-infused applications to dip further within the overall application market.
- Sixty percent of software buyers will expect AI functionality from existing vendors. Sixty percent of software buyers, and likely more over time, expect to receive AI functionality from existing vendors, rather than custom-creating their own applications.
- AI-infused applications will be unable to sustain premium-product status. Currently, 10% of vendors are offering AI-infused apps at differentiated prices. As vendors add more AI functions, the ability to charge a premium for AI will be lost in competition.
The report further states that AI maker platforms used for creating highly customized solutions and AI facilitator platforms used for applications including computer vision and natural language virtual assistants have the strongest growth potential. Other AI market segments likely to grow include AI-centric applications for specialized medical tasks and AI-infused applications that create differentiated products through added AI functionality.
“While we’re seeing high demand for AI technology, platforms, and applications, AI’s ubiquity will ultimately make the technology commonplace in software development,” said Andrew Bartels, VP and principal analyst at Forrester. “We believe investors are defining the AI market too hyperbolically. They are mistakenly including categories that are loosely influenced by or distantly adjacent to AI software. As business leaders rely more and more on AI as a tenet of their digital transformation strategy, they will likely expect their vendors to add AI functionality at no additional cost to them.”

BASIC AC THEORY I I DIRECT CURRENT (DC) ALTERNATING CURRENT (AC) I I Figure Direct vs alternating current distribution systems that are far more efﬁcient than DC, and so we ﬁnd AC used predominately across the world in high power applications.
Phasors are to AC circuit quantities as polarity is to DC circuit quantities: a way to express the “directions” of voltage and current waveforms. As such, it is difficult to analyze AC circuits in depth without using this form of mathematical expression. Phasors are based on the concept of complex numbers: combinations of “real” and “imaginary” : Tony R. Kuphaldt. BLAH! But it will have to do. Since AC is alternating current, and by looking at in on an oscilloscope you see a sine wave that is about 60 volts peak to peak, so the diodes do what they do (which is to only let current flow in one direction,) and pass voltage to give us a new waveform. Not the sine wave from before but hopping waveform.

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.
Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps. Alternating current, or ac, theory is concerned with the mathematical analysis of the steady-state behaviour of electrical circuits in which the currents and voltages vary periodically with time.
The analysis is simplified by considering only sinusoidal variations, an approach which is not restrictive since any general periodic waveform can be Author: A. Pointon, H. Howarth. Direct Current (DC) Direct current is a bit easier to understand than alternating current.
Rather than oscillating back and forth, DC provides a constant voltage or current. Generating DC. DC can be generated in a number of ways: An AC generator equipped with a device called a "commutator" can produce direct current.

As established in the first part of AC Circuit Theory, when a magnet rotates around a coil or a coil rotates around a magnetic field, an Alternating current or voltage is rotation of either the magnet or the coil which leads to the periodic alternation in direction and magnitude of the Voltage (or current) leads to the generation of some sort of wave when viewed on.

An unstable water jet, similar to the one shown in the flow instability section above, was not disturbed deliberately, but was allowed to rise to a free water surface. On contact with the surface, a slight jet asymmetry caused an asymmetrical raised surface that fed back to the jet origin and began a process that looked like a weak version of. In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz elicit an auditory percept in humans.
