摘要： A temperature input unit includes a disconnection detection circuit that measures a temperature of a measurement target with at least one of a thermocouple or a temperature measurement resistor and feeds a disconnection detection current for disconnection detection to the thermocouple and a compensating wire connected to the thermocouple. A controller controls, before measuring the temperature of the measurement target with the thermocouple, a terminal switch and an input circuit switch to connect the compensating wire to a temperature measurement resistor input circuit and an A/D converter, and calculates a predicted value of a voltage drop resulting from resistance of the compensating wire occurring in response to the disconnection detection current. The controller controls the terminal switch and the input circuit switch to connect the compensating wire to a thermocouple input circuit and the A/D converter, and subtracts the predicted value from a measured value of the thermoelectromotive force detected by the thermocouple input circuit to calculate a corrected measured value of the thermoelectromotive force.

摘要： Various embodiments include an electronic circuit for driving a thermocouple element comprising: contact electrodes for connecting cold-end electrodes of the thermocouple element; and a measurement circuit to measure a thermo-voltage generated by the thermocouple element. One of the electrodes is connected to a supply voltage and a ground potential over a voltage divider having resistors with pre-defined resistance values such that a common mode voltage between the contact electrode and the ground potential is in a pre-defined range. If a leakage resistance effective between the contact electrode and the ground potential is greater than a pre-defined threshold, a processor compares the common mode voltage to the pre-defined range and generates a calibration value for the measurement circuitry if the common mode voltage is outside the range.

摘要： A thermocouple assembly may feature a plurality of temperature sensors formed by thermocouple junctions. The sensors may be disposed within an inner diameter of the tubular element and sealed within the tubular element by thermally conductive material. An air gap may be defined by the thermally conductive material and the interior diameter of the tubular element between each pair of adjacent temperature sensors to improve thermal isolation.

摘要： RF tags using source addresses to locate stations on a Wi-Fi network are secured. An RF location server receives a pseudo source address of an RF (radio frequency) tag from a station. The station obtains the pseudo source address while being within radio range of the RF tag and the station receiving a beacon frame from the RF tag. A source address for the RF tag is looked-up utilizing the pseudo source address, and a specific location for the RF tag is looked-up utilizing the source address. Some embodiments store the locations in association with the pseudo address. Either way, the specific location of the station is identified based on the source address of the RF tag. An action is determined in response to at least the specific location of the station. Information related to the action is sent to the station for output to a user of the station. For example, a location-based offer or service can be provided in real-time with a consumer's presence to relevant products or services.

摘要： A method and corresponding software for automatically validating a computer platform thermal solution. An application program is employed to selectively execute thermal stress code to cause the platform's processor to dissipate an amount of power corresponding to a predetermined value, such as a thermal design power dissipation value specified by the processor's manufacturer. In one embodiment, tests are performed while operating at this power dissipation level to determine if a thermal overload condition exists, which may be determined by the processor's temperature, an indication that the processor is throttled, or a signal provided by the processor indicating the processor has detected a thermal overload condition. In another embodiment, a thermal resistance value is calculated based on the processor power dissipation, the temperature of the processor, and the ambient temperature of the test environment. In one embodiment the entire validation process is automatically performed by the application program without requiring any extraneous test equipment or temperature probes.

摘要： Accurate dynamic pressure data in a changing thermal environment is obtained through the use of a pressure gage formed from polyvinylidene fluoride (PVDF) polymer material. The temperature compensation pressure gage has three major elements: an active PVDF transducer which obtains remote pressure readings which are uncorrected for thermal effects; a thermocouple having a short rise time allowing an output thermal signal which dynamically responds to changing thermal conditions; and a compensation amplifier circuit receiving the uncorrected pressure readings and the dynamic thermal signal and producing an output signal representing accurate pressure data which is corrected for changing thermal conditions. Also disclosed are the details of making an active PVDF transducer.

摘要： A circuit is provided for measuring the effect of temperature on the voltage drop across the semiconductor junction sensor which is located remotely from the measuring circuit and connected thereto by a pair of conductors having substantial lead resistance. The circuit provides a programmed current source which alternately provides to the sensor first and second currents of different magnitudes having a fixed ratio to produce corresponding voltages across the conductors wherein each voltage includes a lead component arising from the lead resistance and the respective current. A sample and hold circuit measures each of the voltages and an amplifier multiplies one of the voltages by the current ratio and the resultant voltages are compared to obtain an output free of any lead component and which varies with the temperature of the sensor.

摘要： A thermocouple may have a first thermoelement wire formed of a first material and a first sheath covering at least part of the first thermoelement wire. The first sheath may provide thermal insulation and may be formed of a third material, different from the first material, that is subject to oxidation in response to exposure to a surrounding material. The thermocouple may further have a second sheath covering at least a first portion of the first sheath. The second sheath may act as a barrier between the first portion of the first sheath and the surrounding material and may be formed of a fourth material that is resistant to oxidation in the surrounding material. The first thermoelement wire may be joined, at a junction, with one of the first sheath, and a second thermoelement wire formed of a second material different from the first material.
