Systems and methods for monitoring and/or controlling a temperature related condition of an item, including from a location different than a location at which the food item is located, are disclosed. At least one remote unit has a temperature sensor, a computing device configured to analyze measured temperature data, and a user interface. The user interface displays information regarding a temperature related condition of the item via light or visual signals. A control unit may wirelessly communicate with the remote unit. The control unit may be used to program the user interface to display particular light or visual signals in response to particular temperature related conditions. The control unit may instruct a temperature control mechanism to adjust the temperature of the item.

An apparatus and method for measuring air conditioning output temperature to ensure the proper amount of refrigerant for refilling or servicing a coolant system, such as an automobile coolant system, are disclosed. In one embodiment, the apparatus includes a measurement display for viewing the temperature of air conditioning output inside a vehicle while the user is outside the vehicle refilling or servicing a coolant system. The measurement display is in communications with a temperature sensor measuring the air temperature at a vent inside the vehicle to allow a user to ensure the proper amount of coolant is refilled.

A temperature monitor, a temperature monitoring system, and method are provided. The temperature monitor includes an electronic paper display and a passive temperature sensor. The electronic paper display has first and second display states. The passive temperature sensor is coupled to the display such that when the temperature of the sensor attains a predetermined value, the display changes from the first display state to the second display state.

A Proportional-To-Absolute-Temperature (PTAT) current source is used for high-resolution temperature measurement. The PTAT current source is coupled to a capacitor for a fixed amount of time so as to charge the capacitor to a voltage which is proportional to the current applied to the capacitor, and thus proportional to the temperature. The voltage on the capacitor is measured, and a temperature is calculated or determined from the measured voltage.

A display device is arranged in a faucet at a temperature detection zone to detect a temperature of water flowing therethrough and includes a sealing housing formed therein with an upper receiving space and a lower receiving space in communication with each other and having a bottom having a discharge hole extending therethrough; a circuit board arranged in the upper receiving space; a display module electrically connected with the circuit board; a temperature detection unit electrically connected with the circuit board and partly exposed outside the sealing housing; a hydraulic power generation module arranged in the lower receiving space and electrically connected with the circuit board, the display module, and the temperature detection unit; and a bottom cover fit to the bottom of the sealing housing in a manner of not covering the discharge hole and having a lower opening for entry of the mixture warm water.

A temperature display device capable of accurately displaying a temperature history at any elapsed time, includes a base material; a time-information-to-be-printed portion formed on the base material; and a temperature indicator formed on the base material, the temperature indicator including a photochromic layer.

A system includes: an electrical connector that includes: an electrically insulating housing that defines an interior region; a conductive shell on the insulating housing; and an electrical conductor in the interior region. The system also includes a thermal sensing apparatus that includes: a temperature sensor; and a temperature display visible from an exterior of the electrical connector. The temperature display is configured to provide a persistent indication of a maximum temperature measured by the temperature sensor after the temperature measured by the temperature sensor has decreased relative to the maximum.

Provided herein is temperature sensing circuit. The temperature sensing circuit may include a bandgap voltage generation circuit configured to generate first to third reference voltages independent of temperature change, a temperature compensation circuit configured to output a compensation voltage based on a temperature depending on the first reference voltage, a fixed voltage generation circuit configured to generate fixed voltages independent of the temperature change depending on the second and third reference voltages, and a converter configured to output a temperature code in response to the compensation voltage and the fixed voltages.

A multi-function cooking tool includes a housing, an electronic visual display provided on the housing, and a temperature probe coupled with the housing. The temperature probe is moveable between a first position in which the temperature probe is stored inside the housing and a second position in which the temperature probe extends from the housing. A control system is disposed in the housing and is in communication with the temperature probe and the visual display. When the temperature probe is in the second position the control system is programmed to display information on the visual display that corresponds to temperature readings sensed by the temperature probe. When the temperature probe is returned from the second position to the first position the control system commences a count-up timer program that displays on the visual display the amount of time that has elapsed since the temperature probe was moved from the second position to the first position.
