  • Patent number: 11036266
    Abstract: The disclosed embodiments relate to methods, systems and apparatus for dynamic temperature aware functional safety. The disclosed embodiments provide adaptive techniques to track extended dynamic temperature range of a System-on-Chip (SOC) and automatically tune critical IP components of the SOC so that system can operate reliably even at high temperatures. The disclosed embodiments relax the overdesign of the SOC components by reusing existing components such as a ring oscillator to determine temperature at different regions of the SOC. In one embodiment, the disclosed principles use a Calibrated Ring Oscillator (CRO) temperature sensors. The CRO-based temperature sensors provide fast temperature measurement suitable for detecting dynamic temperature ranges and temperature rate of change. The CROs are existing on the SOC and do not require addition of additional sensors.

  • Patent number: 9488618
    Abstract: Eddy current non-destructive examination and evaluation of physical properties of a component, such as a generator retaining ring, after experiencing potentially degrading thermal exposure during any stage of manufacture, assembly and service use, is performed to determine whether it is acceptable for service use, requires further modification (e.g., additional heat treatment processing) or whether is permanently unsuitable for service. Eddy current test measurements are correlated with component temperature exposure (e.g., absolute temperature and/or cumulative time-temperature heat absorption) and cumulative alteration of the component physical properties, such as, among others, material yield strength (YS), toughness, and tensile ductility. Using the eddy current test measurements and reference data correlating electrical conductivity with ring material thermal exposure, the component's physical properties are evaluated to determine its serviceability.

    Abstract: An I/O circuit for measuring temperatures uses multiple cold-junction compensation sensors permanently affixed near the terminals of the terminal block in order to compensate significant temperature variation across the terminals of the I/O module (up to 3° C.) that can substantially affect the accuracy of thermocouple measurements. The use of these multiple sensors is enabled by a compensation system that corrects for the distance between the built-in sensors and the terminals, a multiplexer that accommodates the additional signal burden produced by the sensors, and a compensation system that allows low-cost sensors to be used and calibrated to as little as a single high accuracy sensor. In one embodiment, a third temperature sensor with relatively higher accuracy is used to compensate for lower accuracy of permanently affixed sensors.

    Abstract: In one embodiment, a current sensing circuit corrects for the transient and steady state temperature measurement errors due to physical separation between a resistive sense element and a temperature sensor. The sense element has a temperature coefficient of resistance. The voltage across the sense element and a temperature signal from the temperature sensor are received by processing circuitry. The processing circuitry determines a power dissipated by the sense element, which may be instantaneous or average power, and determines an increased temperature of the sense element. The resistance of the sense element is changed by the increased temperature, and this derived resistance Rs is used to calculate the current through the sense element using the equation I=V/R or other related equation. The process is iterative to continuously improve accuracy and update the current.

    Abstract: A heat sensor has the ability to correct for errors introduced during temperature changes of the hot junction of the thermopile for the heat sensor. For example, the effect of temperature changes at the hot junction of the heat sensor relative to the cold junction is mathematically modeled such that the effect on the temperature determination can be corrected given certain information relating to the thermopile, its electrical output, and the temperature history and current temperature of the cold junction. By accounting for these factors, a processing device can modify the temperature determination output for the heat sensor while correcting for error introduced by temperature changes at the hot junction as determined by the mathematical model.

  • Publication number: 20140288868
    Abstract: This system can capture information about conditions or events that may have impacted goods which had been stored for shipment or warehousing. This may include time-of-departure, geo-position, in-transit temperature ranges and time the shipment may have been maintained outside required temperature levels. Information may also include motion or acceleration data which may correlate to driving incidents or mishaps. This information is harvested from sensors that are fixed inside the storage crates or shipping cases, captured wirelessly, analyzed and reported out through the internet to a secure server. Additional time and date stamped data is obtained from warehouse attendants, drivers or receiving personnel who can file photographic evidence of signed receipts, damaged goods or crushed crates to the same secure servers. This information can be made available before the goods are received. This data could suggest a particular shipment should be closely inspected.

  • Patent number: 8803799
    Abstract: In a screen protection system and method, a first operation temperature of an electronic device is detected from each of one or more first temperature sensors, and a first ambient temperature is detected from a second temperature sensor, when a display screen is activated. Once there is no operation on the electronic device, a timer is started timing. Once the electronic device is being operated, a duration is temporarily stored and the timer is reset. If the duration is equal to a screensaver time, a second operation temperature of the electronic device is detected from each of the first temperature sensors, and a second ambient temperature is detected from a second temperature sensor. The method further determines whether the electronic device is currently being held by a hand of a user, according to the above-mentioned temperatures. If the electronic device is not being held by a hand of the user, the display screen is controlled to be in an inactive state.

    Abstract: A diagnostic system and a diagnostic method for a thermistor amplifier circuit are provided. The system includes a transistor electrically coupled to a controllable variable resistor having a predetermined resistance. The transistor applies a test voltage signal to the circuit indicative of a first temperature value. An amplitude of the test voltage value is indicative of a simulated thermistor temperature value. The microprocessor determines a test temperature value based on the amplitude of an output voltage of the circuit. The microprocessor also determines an inaccuracy value based on the test temperature value and the simulated thermistor temperature value.

  • Patent number: 8783949
    Abstract: A self-calibrating, wide-range temperature sensor includes a current reference, impervious to process and voltage, with the current reference mirrored into two oppositely-sized bipolar transistors or diodes. Duplicate current sources are used with a ratio of geometries between them, such that the larger current biases the smaller bipolar transistor (less cross-sectional area) and the smaller current source biases the larger bipolar transistor (higher cross-sectional area). The current source in conjunction with the differential temperature sensing provides inherent calibration without drift while the differential sensing, from the ratio of geometries in the current paths also increases sensitivity.

  • Patent number: 8786449
    Abstract: A system and method are provided for using a thermal management core to control temperature on a system-on-chip (SoC). The method provides an SoC with an internal thermal management core and an internal temperature sensor. For example, the sensor may be located on or near a processor core die. The thermal management core monitors temperatures recorded by the SoC temperature sensor, and sends commands for controlling SoC device functions. In response to these commands, the thermal management core monitors a change in the temperature at SoC temperature sensor. The temperature sensor may be monitored via a dedicated SoC internal interface connecting the processor and the thermal management core. Alternately, the thermal management core may poll for temperatures via a system management bus (SMBUS) SoC external interface connecting the processor and thermal management core. Further, a dedicated SoC external alert interface connecting the processor and thermal management core may be monitored.
