Spring Testing to Make Trampolines Safer

b2ap3_thumbnail_PowerBounce-Trampoline-Detail.gif

A leading manufacturer of Trampolines for sports and fitness applications wanted to test the strength and longevity of the springs used to build the trampolines.  They turned to Loadstar Sensors' iLoad Mini Load Cells to test the Force vs. Deflection characteristic of the springs.  In addition they needed to see how well the springs held up after millions of cycles of load applied to them.  

So they built a testing machine that applied a tension and compression cycle every few seconds and applied this load to their springs in series with our iLoad Mini load cell.  The results they got from the test helped them refine the design and ensure that their product would be a quality product that protected the safety of its users and also lasted for many millions of cycles of use with minimal sagging.

Boxing Training Tool - Measure Punch Forces and Number of Punches

Boxers who want to be at the top of their game, wanted a tool to help them track how many punches they can throw in a minute, how hard the punches are, how long they can sustain the number and intensity of the punches and track the progress they made from session to session or week to week.

In order to provide such a tool, we developed our Punch Force Sensor solution with USB output.  The first image shows the punching area with a All-in-One PC above it.  The sensor is connected to a high speed load cell Interface via USB shown in the second image.  The last image shows the software screen that displays the intensity of the punch as well as the number of punches thrown in a session.

USB Force Sensor helps to train volunteers to do CPR

At least one in ten of us, in our lifetime, will see a family member, friend, or acquaintance have a cardiac arrest.  If the victim of a cardiac arrest or stroke has to wait for the Ambulance to show up and a paramedic to start CPR, the outlook for surviving the attach and full recovery is bleak.  Fewer than 10% of the victims of a cardiac arrest will get out of the hospital with brain functions intact and about 14% of the survivors will have significant neurological problems.

An innovative aircraft startup company trying to build a long range passenger jet with several times the range of currently available jets used our RAL1 Pancake Load Cells with USB Output to perform performance and strength testing of the wing and flaps as well as get a profile of the weight distribution of the wing during manufacture.  The USB Output from the load cells make it easy to gather data into a single file and monitor the Force vs. Time performance in real time on a PC.

NASA uses our S-Beam Load Cells with USB Output to Test Forces on a Parachute

Parachutes bring Orion Capsule Down Safely during Test

NASA Ames Research center used two of our RAS1 S-Beam Load Cells and one RES2 S-Beam Jr. Load Cell with matching DI-1000U 24-bit USB Load Cell Interfaces and our LV-4000 software to measure the forces acting on a parachute during a test conducted in the giant wind tunnel facility.

The  solution provides a fully calibrated and accurate system which can be used to measure both tension and compression forces in real time.  The software allows the user to display the data in various units, log the data to a comma separated file as well as plot the data as a Force vs. Time plot in real time.

Measuring the Recoil Force from a Gun

 Dr. Mattew Hall, a faculty member in the Thermal/Fluids Systems program in the Department of Mechanical Engineering at the University of Texas, used one of the early versions of our analog load cell with a 0-5 VDC output to  measure the recoil force from a variety of guns.  The lower the recoil force, the easier it is to handle the gun and the smaller the impact on the shoulder or wrists of a user.  

You can now use our iLoad Series Analog load cells for this purpose.  The advantage of using the iLoad, iLoad Pro Analog load cell or the iLoad Mini + DQ-1000A Analog Load Cell Solution  is that you get a 0.5 to 4.5 VDC output proportional to the applied force/load.  You do not need a signal conditioner/amplifier to measure the loads with your Data Acquisition System.  Most DAQs accept a 0-5 VDC input on their Analog Input channels.
