A temperature measuring device and a temperature measuring method are provided which are capable of obtaining precise measured temperature values with respect even to old persons, sucklings or infants, which device may be formed into a disposable type according to need, which method may be carried out using such a disposable type device according to need, and which enable precise temperature measurement in real time. An on-subject temperature measuring device 1, which is attached to a subject when a temperature of the subject is measured, receives a radio wave from a reader 2 as an external device and is thereby electrically powered. Using the electric power, temperature measurement is performed in the on-subject temperature measuring device 1. The results of the measurement are transmitted through radio waves to the reader 2 in the form of a temperature of the subject and ID data. The reader 2 is so constructed as to be connectable to a personal computer (not shown), and data processing by the personal computer is performed according to need.

The invention relates to a temperature probe for an oven, comprising in one embodiment a longitudinal housing in the form of a spit. A temperature sensor and an electronic unit are arranged in a tip and are connected at the other end to emitting means. The temperature probe comprises a thermogenerator for producing energy. The thermogenerator uses a temperature difference between a higher temperature inside the oven and a lower core temperature in a food product, such as roast, in which the temperature probe is inserted, for producing energy for operating the emitting means.

A system displays information from and controls electrical switching apparatus, such as circuit breakers. The system includes a plurality of circuit breakers having separable contacts and a plurality of conditions, such as bus temperature and contact wear. A plurality of sensors are structured to sense the conditions of the circuit breakers and to communicate the sensed conditions over corresponding wireless signals. A display and control unit is operatively associated with the circuit breakers and is structured to receive the corresponding wireless signals and display information corresponding to the sensed conditions or to control the circuit breakers based upon one or more of the sensed conditions.

A digital temperature sensor and a system and a method for measuring a temperature are provided. The system includes a reference signal generator including one or more resistance elements; a temperature sensor including a plurality of discrete resistance elements arranged parallel with one another; a multiplexer multiplexing the plurality of discrete resistance elements and the reference resistance element so that the plurality of discrete resistance elements sequentially distribute a power voltage together with the reference resistance element; a comparator having the voltages distributed by the reference resistance element and a discrete resistance element selected by the multiplexer; and a counter counting sequential switchings of the multiplexer. The counter information of the output level transit time of the comparator is provided to the controller, and the system obtains temperature information according to temperature change information from turn information of the discrete resistance elements according to the counter information.

Techniques for enhancing thermal design of a system having a number of boundary values are provided. A method for such enhancement includes representing thermal response of the system to the boundary values, obtaining at least one constraining parameter, and determining spatial and / or temporal distribution of the boundary values. The thermal response is represented as a superposition of temperature fields associated with given boundary values. The spatial and / or temporal distribution of the boundary values is determined based on the thermal response represented in the representing step, so as to satisfy the constraining parameter. The boundary values can be, for example, power sources, and the at least one constraining parameter can be, for example, a spatial or temporal location of one of the power sources.

A temperature sensing device accurately determines the core temperature of a warm blooded animal or human based on at least one measurement of the temperature of the skin of the warm blooded animal or human. The device includes a housing, and a first contact type temperature sensing element coupled to the housing. The first contact type temperature sensing element includes a first temperature sensor that is operative to measure the temperature of the skin when the first contact type temperature sensing element is in contact with the skin. The first temperature sensor produces at least a first signal representative of the measured skin temperature. An electronic circuit uses the first signal to determine the core temperature of the warm blooded animal or human. An electronic communication device, such as a display, is coupled to the electronic circuit for communicating the core temperature to a user.
