  • Patent number: 10761769
    Abstract: A memory sub-system is disclosed that makes accessible accumulated memory temperature statistics in relation to a target memory portion. This can be accomplished by maintaining one or more hold variables and one or more accumulation variables. The accumulation variables can be iteratively updated upon triggers such as a timer expiration or I/O event. Updating the accumulation variables can include obtaining a current temperature and tracking one or more of: a maximum, minimum, and mean temperature across the iterations. An accumulation value can track how many times the accumulation variables have been updated. When the accumulation value reaches an accumulation action threshold, the current state of the accumulation variables can be used to update the hold variables. The accumulation value and accumulation variables can then be reset and used for accumulation of additional temperature statistics.

The temperature of the environment can be determined on a cycle-by-cycle basis, and is usable for implementing advanced combustion strategies such as HCCI and SACI.

  • Patent number: 9016937
    Abstract: An electrical temperature sensor (10) comprises a liquid crystalline material (12). First and second electrically conductive contacts (14), (16), having a spaced relationship therebetween, contact the liquid crystalline material (12). An electric property measuring device is electrically connected to the first and second contacts (14), (16) and is arranged to measure an electric property of the liquid crystalline material (12). The liquid crystalline material (12) has a transition temperature T at which it undergoes a phase change between polar and non-polar phases. The phase change between polar and non-polar phases causes a change in said electric property of the liquid crystalline material (12).

  • Patent number: 8967855
    Abstract: An electronic device that determines an external temperature is described. During operation, the electronic device uses a sensor mechanism (such as an integrated temperature sensor) to determine an internal temperature of the electronic device. Then, a thermoelectric device (which may be based on the Peltier effect and/or the Seeback effect) determines the relative temperature difference between the internal temperature and the external temperature. Next, the external temperature may be determined based on the internal temperature and the temperature difference. For example, the external temperature may be determined relative to a threshold value. Furthermore, an electrical signal (such as a voltage or a current) output by the thermoelectric device may be used to recharge a battery and, more generally, a power source in the electronic device.

  • Patent number: 8961004
    Abstract: Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and/or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and/or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.
