  • Patent number: 11566948
    Abstract: A method, apparatus and system for measuring a temperature can involve measuring a voltage with a resistance temperature detector using a variable excitation current, and deriving a process temperature from the voltage measured by the resistance temperature detector. The process temperature can be further derived by applying a plurality of values of the variable excitation current, measuring corresponding values of voltage, and estimating a resistance by applying a least square estimation. The process temperature can also be derived by applying a different value of the variable excitation current at every iteration, using a recursive least square estimation to measure a resistance, and using confidence intervals for instrument diagnostics.

  • Patent number: 9267848
    Abstract: The thermometer using differential temperature measurements utilizes a pair of adjacent temperature sensors in order to measure the temperature of a common surface over a pre-selected period of time. The thermometer includes a housing and first and second thermistors mounted adjacent one another on the housing. The first and second thermistors are positioned against the surface, which can be a body part (for oral, rectal or axial body temperature measurements) or can be any other desired surface for which a spot check temperature reading is desired. A programmable current source pre-heats the second thermistor to a pre-selected temperature, while the first thermistor is initially at room temperature. A controller inside the housing causes both the first and second thermistors to take instantaneous temperature measurements of the surface at two successive times. The controller linearizes the measurements to predict the temperature of the surface, which is then displayed to the user.

  • Patent number: 8497759
    Abstract: The RTD device of the present invention is comprised of a semiconductor substrate and a substantially thin conductive metal layer disposed upon the semiconductor substrate, wherein the conductive metal has a substantially linear temperature-resistance relationship. The conductive layer is etched into a convoluted RTD pattern, which consequently increases the overall resistance and minimizes the overall mass of the RTD assembly. A contact glass cover and a conductive metal-glass frit are placed over the RTD assembly to hermetically seal the RTD. The resultant structure can be “upside-down” mounted onto a header or a flat shim so that the bottom surface of the semiconductor substrate is exposed to the external environment, thus shielding the RTD from external forces. The resultant structure is a low mass, highly conductive, leadless, and hermetically sealed RTD that accurately measures the temperature of liquids and gases and maintains fast response time in high temperatures and harsh environments.

  • Patent number: 8162541
    Abstract: A two-terminal temperature sensor connects a first end of thermistor or other thermometer device to a first electrical terminal via an inner compression coil. A second electrical terminal is connected to a second end of the thermistor via an outer compression coil and a formed conductor. The inner compression coil and thermistor are positioned within the formed conductor. The inner compression coil and thermistor are prevented from contact with the formed conductor by an inner insulating tube. The first and second electrical contacts are mounted in a molded terminal assembly that insulates the electrical contacts from one another. The entire assembly is housed within a housing that is electrically isolated from the formed conductor and outer compression coil via an outer insulating tube and an insulating disk.

  • Patent number: 8115585
    Abstract: In a variable resistance element having a variable resistor between first and second electrodes and changing its electric resistance when a voltage pulse is applied between both electrodes, data holding characteristics can be improved by increasing a programming voltage and programming in a high current density. Therefore, a booster circuit for supplying a high voltage is needed when the variable resistance element is applied to a nonvolatile memory. When the smaller of the areas of the contact regions between the first electrode and variable resistor and between the second electrode and variable resistor is set to the electrode area of the variable resistance element, it is set within a specific range not larger than the predetermined electrode area. Thereby the programming current density can be increased without raising the programming voltage, and the variable resistance element having preferable data holding characteristics even at a high temperature can be provided.
