A temperature sensor malfunction diagnosis apparatus is provided in a vehicle that includes a device, a refrigerant circuit, an electric pump, a battery, and a temperature sensor, and configured to diagnose malfunction of the temperature sensor. The temperature sensor malfunction diagnosis apparatus includes a pump driver and a malfunction diagnosis unit. The pump driver is configured to drive the electric pump after stopping of driving of the vehicle, on the basis of the battery as a power supply. The malfunction diagnosis unit is configured to perform a malfunction diagnosis of the temperature sensor, on a condition that a charged time reaches a temperature converging time of the temperature sensor while the electric pump is driven. The charged time is a time during which charging of the battery is performed from start of the charging of the battery.

A device comprises a plurality of temperature sensing elements and a control module. The plurality of temperature sensing elements are each arranged proximal to a respective current carrying blade of an electrical plug. The control module receives, from the plurality of temperature sensing elements, a plurality of temperature signals that each indicate a temperature associated with the respective current carrying blades of the electrical plug. The control module also determines a temperature condition of the electrical plug based on the plurality of temperature signals. The control module also communicates an indication of the temperature condition of the electrical plug via an electrical power carrying conductor that supplies electrical power via the electrical plug.

The bandgap-less apparatus is a fast settling circuit (e.g., with settling time of less than 40 ns) that can leverage proportional-to-absolute-temperature only (PTAT-only) currents to generate a zero or substantially zero temperature coefficient, or even complementary-to-absolute-temperature (CTAT), reference current or voltage, without the need of a native CTAT component or bandgap diodes. The apparatus subtracts two different PTAT currents so that the resulting current is zero-TC. The resulting current is a reference current. The resulting current can be converted to a reference voltage.

Temperature data is wirelessly received from a food thermometer inserted into food. A remaining time for cooking the food is estimated based at least in part on the received temperature data. The progression of a recipe to at least two new stages is indicated on a user interface based on the received temperature data. According to one aspect, the food thermometer includes a thermal sensor configured to measure an internal temperature of the food or an ambient temperature adjacent the food. It is determined that the indicated temperature measured by the thermal sensor increased by at least a threshold value from a previously indicated temperature wirelessly received from the food thermometer, and the progression of the recipe is indicated on the user interface to a new cooking stage.
