  • Patent number: 10719091
    Abstract: A method for use in temperature control includes a step of associating a first setting of an adjustable device with a first temperature. The method may include a step of associating a second setting of the adjustable device with a second temperature. The method may include a step of determining a set-point temperature from a set-point setting of the adjustable device, the first and second settings of the adjustable device, and the first and second temperatures. The first and second temperatures may define a temperature range over which temperature is to be controlled. Such a method may allow a user to select or define a temperature range over which an object, system or environment is to be controlled from within a maximum operating temperature range of a temperature sensor. Such a method may allow a user to select or define a set-point temperature from within the selected temperature range.

  • Patent number: 9851698
    Abstract: A process variable transmitter provides an output representing a process variable. The process variable transmitter includes a process variable sensor that provides an analog sensor signal representing a process variable, an analog to digital converter that receives the analog sensor signal from the process variable sensor and converts it to digital sensor signal values, and a compensation processor. The compensation processor calculates, in a first mode, a compensated process variable value at a first slow rate. The compensation processor calculates a compensation factor relating the compensated process variable value to an initial digital sensor signal value. The compensation processor calculates, in a second mode, a process variable estimate as a function of an updated digital sensor signal value and the compensation factor. The process variable estimate is calculated at a second rate faster than the slow rate.

    Abstract: A monitoring circuit for an integrated circuit comprises a non-temperature-inverted circuit and a temperature-inverted circuit. Operating parameters of the two circuits are measured, representing the propagation speed of signals in the respective circuits. In response to a change in temperature, the non-temperature-inverted circuit slows down and the temperature-inverted circuit speeds up. In contrast, in response to a change in operating voltage both circuits either speed up or slow down. This divergence in response to temperature and similar response to voltage enables the monitoring circuit to distinguish between changes in operating voltage and changes in operating temperature.

Alternatively, such a temperature sensor may be used on disposable chemical sensors where the impedance element is made of a common metal as conductors that connect a sensor reactant to sensor contacts.

    Abstract: The present invention relates to the use of one or more amplicons as temperature calibrators. In some embodiments, the calibrators may be used to calibrate the temperature of a microfluidic channel in which amplification and/or melt analysis is performed. In some embodiments, the amplicons may be genomic, ultra conserved elements and/or synthetic. The amplicon(s) may have a known or expected melt temperature(s). The calibrators may be added to primers of study or may follow or lead the primers of study in the channel. The amplicon(s) may be amplified and melted, and the temperature(s) at which the amplicon(s) melted may be determined. The measured temperature(s) may be compared to the known temperature(s) at which the amplicon(s) was expected to melt. The difference(s) between the measured and expected temperatures may be used to calibrate/adjust one or more temperature control elements used to control and/or detect the temperature of the channel.

  • Publication number: 20120170608
    Abstract: A method of calibrating a temperature sensor of a chemical microreactor envisages: determining an airflow along a path in such a way as to cause a thermal exchange between the airflow and a chemical microreactor, which is provided with an on-board temperature sensor and is set along the path; and detecting a temperature in the airflow downstream of the microreactor, in conditions of thermal equilibrium.

  • Publication number: 20120140789
    Abstract: The present application is directed to a system for verifying calibration of a temperature sensor comprising an above-ambient temperature verifier and a below-ambient temperature verifier. The above-ambient temperature verifier includes a first housing containing an ohmic material. At least one pair of electrodes is provided to direct an applied current through the ohmic material to heat the material. A well is provided within the ohmic material for accepting a temperature sensor. A compression assembly cooperates with the ohmic material to create intimate contact with the temperature sensor. An above-ambient reference temperature monitor maintains a calibrated temperature within the ohmic material. The below-ambient temperature verifier includes a second housing and a below-ambient reference temperature monitor to maintain a calibrated temperature of a below-ambient temperature medium.

  • Publication number: 20120106590
    Abstract: A thermostat diagnostic apparatus is provided with a cooling medium temperature sensor, an engine operating condition sensor and a malfunction diagnosing device. The malfunction diagnosing device is configured to diagnose a stuck-open malfunction of a thermostat provided in a coolant flow passage of an engine installed in a mobile body based on a comparison of a real cooling medium temperature detected by the cooling medium temperature sensor and an estimated cooling medium temperature estimated based on an engine operating condition of the engine detected by the engine operating condition sensor. The malfunction diagnosing device determines that the thermostat is stuck in an open state upon determining that either the estimated cooling medium temperature or the real cooling medium temperature exceeds a prescribed reference value during a period in which an increased heat exchange rate condition of a radiator is satisfied continuously.

  • Publication number: 20120072157
    Abstract: A user computer device is provided that comprises a temperature sensitive touchscreen having a temperature sensitive user interface comprising multiple thermal energy emitter/detector devices, such as thermocouples. The multiple thermal energy emitter/detector devices are capable both of detecting thermal energy and emitting thermal energy. The temperature sensitive user interface generates thermal patterns that may be transferred to other thermally sensitive electronic devices or that may be used to authenticate the user computer device. The user computer device also can detect and thermally communicate with a thermal energy docking station and, based on thermal recognition, activate applications displayed on the temperature sensitive touchscreen. Further, the user computer device can auto-bias a temperature of the temperature sensitive user interface in order to better assure proper operation of the temperature sensitive user interface in all operating conditions.

  • Publication number: 20120061480
    Abstract: A thermostat system is provided that comprises a base thermostat for providing basic thermostat control and a portable information display (PID) unit, or dockable display, that provides an improved user interface. The PID unit can be docked to the base thermostat by being releasably mounted on top of a front portion of the base thermostat. The base thermostat provides control of an environmental control system, allowing the regulation of the temperature in a building. The PID unit may be used when it is mounted to the base thermostat or un-mounted from the base thermostat. The PID unit provides an improved user interface and experience over the base thermostat.

    Abstract: An outside air temperature (OAT) diagnostic system includes an ambient temperature monitoring module that receives (i) an OAT signal from an OAT sensor and (ii) an intake air temperature (IAT) signal from an IAT sensor of an engine. The ambient temperature monitoring module compares the OAT signal to an IAT signal and generates a first difference signal. A performance reporting module determines whether the OAT sensor is exhibiting a fault and generates an OAT performance signal based on the first difference signal.
