  • Patent number: 11680856
    Abstract: A controller configured for detecting a disturbance using a comparison of outputs of at least two sensors and for determining a pressure from the outputs of the at least two sensors. A ratio of the measurement sensitivity and the disturbance sensitivity should be different for the at least two sensors. A method for monitoring disturbances of a sensor assembly includes comparing the outputs of the at least two sensors. The controller and related method provide, while requiring only two sensors, a redundant system that is also able to detect excessive disturbances on a sensor assembly.

  • Patent number: 11674862
    Abstract: A pressure sensing unit, a capacitive hybrid sensor device, and an input apparatus using the same are provided. The pressure sensing unit for detecting pressing events includes a pressure sensing pad group and a floating conductive element. The pressure sensing pad group includes a first pressure sensing pad, a second pressure sensing pad, and a ground pad that are spaced apart from one another. The first and second pressure sensing pads are electrically shielded from each other by the ground pad. One among the floating conductive element and the pressure sensing pad group is configured to be movable in a movement direction relative to another one among the floating conductive element and the pressure sensing pad group. The floating conductive element overlaps with the pressure sensing pad group in the movement direction. Therefore, a signal-to-noise ratio can be increased and an erroneous detection can be prevented.

  • Patent number: 11668616
    Abstract: A stretchable sensor skin is provided, which is a soft tactile sensor sleeve that can cover large areas of a robot, and is both low-cost and robust. It is made of elastomer molded pouches (referred to as sensor taxels) that when contacted transmit pneumatic pressure to off-board barometric sensors, via stretchable channels. The entirely soft makeup of the sleeve makes it highly conformable to 3D curved geometries of a robot. The stretchable channels mean that it can cover joints without wiring getting caught. The stretchable rubber channels are also inherently more robust than stretchable conductor approaches, and the skin lacks fragile soft-rigid interfaces that has plagued many other sensor skins. The fact that there are no conductive components also makes the skin easy to sanitize and waterproof.

  • Patent number: 11660404
    Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

  • Patent number: 11656222
    Abstract: A sensor using ultrasound to detect presence and nature of analyte includes an ultrasonic element and a receptor thereon. The ultrasonic element includes a first electrode, a second electrode facing and spaced apart from the first electrode, an insulating layer between the first electrode and the second electrode, and a vibrating film between the insulating layer and the first electrode. The vibrating film carries the first electrode. A cavity is formed between the vibrating film and the insulating layer. The receptor is on a side of the first electrode away from the second electrode. The receptor can combine with a target substance in a test analyte. When the first electrode and the second electrode are applied with different voltages, certain ultrasound frequencies are generated as the vibrating film vibrates, and the presence and weight of different target substances are indicated by the changes in resonance.
