Abstract: A multi-mode control device is provided for controlling a load device. A high-power interface of the control device can be electrically coupled to a high-power module. An occupancy sensor can receive a first current from the high-power module via the high-power interface, and a trigger detection device can receive a second current that is less than the first current from a low-power module via a low-power interface. The processor can switch the control device from a high-power mode for powering the occupancy sensor to a low-power mode by causing a reduction in the current provided to the occupancy sensor and causing current to be provided to the trigger detection device. The trigger detection device can detect a trigger in the low-power mode. The processor can cause the control device to operate in the high-power mode based on the trigger's detection.

Abstract: A path light that utilizes an ambient light sensor to determine the lighting conditions may experience feedback from its light source if it determines that the lighting conditions are appropriate to illuminate the path light's light source. The path light, as disclosed herein, may compute an offset value to ascertain the amount of feedback from the light source. Upon learning the offset value, the path light may subtract the offset value from a detected amount of light to determine whether the lighting conditions of its surroundings still meet a threshold level of darkness for the path light to illuminate.

Abstract: A smart laser pointer is disclosed in this application that includes a laser coupled to a processor that can disable the laser from operating for a period of time (T) based on a disabling trigger. The smart laser pointer may also include an optical receiver coupled to the processor that detects received laser signals that are emitted from the laser after they are reflected off of a target and a memory storing position information threshold limits. The processor calculates measured position information based on the received laser signals detected by the optical receiver and compares them to the position information threshold limits. A disabling trigger occurs when the position information exceeds the position information threshold limits. The position information and threshold limits may include a distance or a velocity.

Abstract: A memory control component outputs a memory write command to a memory IC and also outputs write data to be received via data inputs of the memory IC. Prior to reception of the write data within the memory IC, the memory control component asserts a termination control signal that causes the memory IC to apply to the data inputs a first on-die termination impedance during reception of the write data followed by a second on-die termination impedance after the write data has been received. The memory control component deasserts the termination control signal to cause the memory IC to apply no termination impedance to the data inputs.

Abstract: An object is to achieve both suppression of operation delay and reduction in power consumption of a programmable LSI. A compiler generates, from source code, configuration data needed in a programmable LSI and a time schedule that shows a timing of using the data in the programmable LSI (a timing at which the data is held in a configuration memory) and a timing of storing the data in the programmable LSI before the data is used. Supply of new configuration data to the programmable LSI from the outside (storage of new configuration data) and data rewrite in the configuration memory in the programmable LSI (circuit reconfiguration) are performed independently and concurrently on the basis of the time schedule.
