Abstract: A lighting device that is capable of discriminating a type of an external power source device connected from among types of connectable devices without increasing the number of terminals of a connector. A connector is electrically connectable to an external power source device and includes a first terminal for supplying electric power from the external power source device to a main capacitor and a second terminal for discriminating a type of the external power source device. An obtaining unit obtains the information for discriminating the type of the external power source device by comparing a voltage value of a signal input to the second terminal from the external power source device with a predetermined voltage threshold when an attribute of the second terminal is set to an input. A discrimination unit discriminates the type of the external power source device by contrasting the information obtained with information stored.

Abstract: In a processor or the like including a reconfigurable (RC) circuit, the RC circuit is used to form a test circuit to test a core, a cache memory, or the like, and then part of the RC circuit is used as an auxiliary cache memory. When a memory can store data after stop of power supply, a startup routine program (SRP) of the processor can be stored therein. For example, after the test, an SRP is loaded to a memory in the RC circuit from an external ROM or the like, and when power is resupplied to the processor, a startup operation is performed using the loaded SRP. When the processor is in a normal operation state, this memory is used as an auxiliary cache memory and the SRP is overwritten. The SRP is loaded to the memory again at the end of use of the processor.

Abstract: One or more embodiments set forth techniques for identifying and locating wireless light emitting elements within a lighting system. An identification and location module executing on calibration system transmits a message to instruct a first light emitting element included in a plurality of light emitting elements within the lighting system to emit light having a first characteristic. The identification and location module detects, via a photosensitive device, a first location of the first light emitting element within the lighting system based on the first characteristic. The identification and location module stores a data entry in a memory that associates the first location with the first light emitting element. At least one advantage of the approach described herein is that wireless light emitting elements are automatically identified and located during post assembly testing, thereby reducing labor costs associated with manually presorting or recording IDs of the light emitting elements.
