  • Patent number: 11125635
    Abstract: A method includes the steps of providing a number of force consolidators between an object and a surface, providing a number of force sensors, each in a different one of the force consolidators, measuring an output of the force sensors, and processing the output of the force sensors to determine a total force exerted between the object and the surface. The force consolidators are each configured to reduce a portion of a surface area of the object into a consolidated surface area such that forces exerted on the portion of the surface area are concentrated in the consolidated surface area. By using the force consolidators along with the force sensors, the total force exerted by the object on the surface may be easily measured using off-the-shelf force sensor technologies.

  • Patent number: 11105937
    Abstract: Devices, systems, and methods of using one or more memristors as a radiation sensor are enabled. A memristor can be attractive as a sensor due to its passive low power characteristics. Medical and environment monitoring are contemplated use cases. Sensing radiation as part of a security system (at an airport for example) and screening food for radiation exposure are also possible uses. The memristor as a radiation sensor may possibly provide an inexpensive and easy alternative to personal thermoluminescent dosimeters (TLD). Memristor devices with high current and low power operation may be attached with wearable plastic substrates. An example device includes two metal strips with a 50 ?m thick layer of TiO2 memristor material. The device may be made large relative to traditional memristors which are nanometers in scale but its increased thickness can significantly increase the probability of radiation interaction with the memristor material.

  • Publication number: 20210257811
    Abstract: A driver circuit includes digital inputs, such as a first digital input and a second digital input. The digital inputs receive voltages at either a digital high-voltage or a digital low-voltage. The driver circuit has a clock input, an analog output, a first differential pair of transistors connected to the analog output, second differential pairs of transistors connected to the analog output, and voltage limiters connected to the clock input and the second differential pairs of transistors. The voltage limiters supply different voltages to the second differential pairs of transistors, which results in the second differential pairs of transistors providing analog signals to the analog output that are at different voltage steps at, and between, the digital high-voltage and the digital low-voltage.
