William H Slater has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11835404
    Abstract: A tension sensor includes a planar tab having a first and second side, first and second end sections and an aperture through each of the end sections. A first strain gage is attached to the first side of the tab. The first strain gage has a tension grid aligned to a longitudinal axis of the tab and a cross-tension grid perpendicular to the tension grid. A second strain gage is attached to the second side of the tab. The second strain gage has a tension grid aligned to the longitudinal axis of the tab and a cross-tension grid perpendicular to the tension grid. The first strain gage and second strain gage are wired in a Wheatstone bridge in which the tension grid and the cross-tension grid of the first strain gage form one side and the tension grid and the cross-tension grid of the second strain gage form another side.

  • Patent number: 11340255
    Abstract: A method for reducing bias drift in electrical-mechanical systems sensor such as an accelerometer is provided. The method includes the steps of arranging at least one accelerometer in a chamber and initiating a plurality of temperature cycle sets. Each temperature cycle set has a minimum temperature, a maximum temperature, and a ramp rate. The conditioning method monitors the accelerometers until a bias drift is stabilized within a desired bias drift range. The minimum temperature and the maximum temperature limit a temperature range in which the accelerometer is cycled. Use of temperature limiting can quickly accelerate stabilization of the bias drift while also reducing degradation.
