  • Patent number: 10006828
    Abstract: Systems and methods for accurately and precisely measuring the resistance of a resistive sensor of a matched resistive sensor pair disposed on opposite surfaces of a substrate. Certain embodiments include coupled each sensor of the matched resistive sensors to a thermally-isolated pair of reference resistors contained within an integrated circuit so as to form a Wheatstone bridge. A controller associated with the integrated circuit can adjust the resistance of the thermally-isolated pair of reference resistors until the ratio of resistances matches to the ratio of resistances between the sensors of the matched pair.

  • Patent number: 9965092
    Abstract: A force-responsive sensor incorporating a force-sensitive element is in communication with a power controller. The power controller changes one or more performance characteristics associated with the force-responsive sensor. A performance characteristic can include a bias voltage or current, a duty cycle, a sampling rate, and so on. The performance characteristic(s) can be changed in response to a touch event or based on an operational setting of the force-responsive sensor (or an electronic device incorporating the force-responsive sensor). Regulation of the performance characteristic(s) reduces power consumption of the force-responsive sensor.

  • Patent number: 9947524
    Abstract: A method of detecting one or more compounds, chemicals or contaminants in a substrate by mass spectrometry is disclosed. A non-living substrate is analyzed by contacting the substrate with a diathermy knife. An electric current is applied to the diathermy knife such that the diathermy knife vaporizes a portion of the substrate. The vapor is aspirated via a sampling tube pumped by a venturi pump into a vacuum chamber of a mass spectrometer. Analyte molecules are aspirated into the vacuum chamber whereupon they impact a surface of the vacuum chamber and are ionized to form analyte ions which are then mass analyzed.

  • Patent number: 9927905
    Abstract: Disclosed herein is an electronic device having a force sensing device. The force sensing device receives a continuous force input which is translated into a discrete event. In order to more accurately determine when the discrete event is to occur, the electronic device includes a two low-pass filters that concurrently receive a force signal from the force sensing device. The first low-pass filter has a first bandwidth and the second low-pass filter has a second bandwidth that is greater than the first bandwidth. The two low-pass filters filter the force signal to provide a user interface with a precise feel for slower more deliberate input while also providing fast response times for stronger, shorter input.

  • Publication number: 20180067612
    Abstract: A strain-sensitive structure includes two resistive structures connected in series and formed on one surface of a substrate. One resistive structure is formed with a first trace arranged in first trace pattern. The other resistive structure is formed with a second trace arranged in a second trace pattern. The first resistive structure is configured to experience strain in response to an applied stress on the substrate. The second resistive structure is configured to experience less strain in response to the applied stress on the substrate compared to the first resistive structure. Together the strain-sensitive structure and the substrate form a force sensing layer that can be included in an electronic device.

  • Publication number: 20180030309
    Abstract: A system for forming an elastomeric composition for application to a substrate includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes a polymeric polyisocyanate and optionally an isocyanate-terminated prepolymer. The isocyanate-reactive component is reactive with the isocyanate component and includes a polyol component and a polyetheramine. The polyol component is a mixture of (a) a hydrophobic polyol; (b) a polyether polyol different than the hydrophobic polyol and having a weight average molecular weight greater than 500 g/mol; and (c) a polyaminopolyol. The elastomeric composition is formed as the reaction product of the isocyanate component and the isocyanate-reactive component and may be applied as an elastomeric coating layer on a substrate such as a steel pipe. The steel pipe having the applied elastomeric coating layer satisfies the standard for use in the water supply industry as set forth in AWWA C222.

  • Patent number: 9805227
    Abstract: Methods and apparatuses for selecting a subset of RFID tags are provided in some embodiments. These methods and apparatuses utilize the susceptibility to light by persistent nodes found in passive tags. Light can be used to intentionally reduce persistence times in a particular subset tags or even an individual tag. Then, persistent nodes can be used as a selection criterion to distinguish previously illuminated tags from non-illuminated tags. In other embodiments, a power circuit receives a RF input source and generates a direct current (DC) output voltage. The circuit includes a bias circuit to supply a gate to source bias, which is independent of the DC output voltage. The circuit further includes a voltage multiplier circuit that is coupled to the bias circuit. The voltage multiplier circuit has MOS transistors with one transistor to receive the gate to source bias.

  • Publication number: 20170300161
    Abstract: An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.
