Abstract: A control system is disclosed for determining an actual temperature of a light emitting diode. The control system uses conductor that supply power to the light emitting diode to supply a pulse to the light emitting diode. The pulse is determined along with a reaction caused by the pulse and the information gained is used in determination of the light emitting diode die temperature which can then be used in controlling current to the light emitting diode to control the temperature of the light emitting diode.

Abstract: An indication apparatus for indicating temperature status of a motherboard includes a detection module, a comparison module, a switch module, and an indication module. The detection module detects temperatures of the motherboard, and converts the detected temperatures to voltage signals. The comparison module receives the voltage signals, compares the voltage signals with a first reference voltage, and outputs control signals according to a comparison result. The switch module receives the control signals, and turns on or off according to the control signals. The indication module indicates temperature states of the motherboard when the switch module turns on or off.

Abstract: The present invention provides a digital linear heat detector with thermocouple heat confirmation. A digital linear heat detector with thermocouple heat confirmation comprises a first conductor and a second conductor, the first conductor composed of a different conductive material than the second conductor. The first and second conductors are then are twisted together to form substantially continuous spring pressure between the first conductor and the second conductor, thereby causing the layers of the non-conductive heat sensitive thermoplastic material to be in contact. The present invention also includes a monitoring circuit that is configured to monitor resistance along the first and second conductors. When the resistance changes along the first and second conductors, the monitor is configured to detect a short and enter a thermocouple mode.
