    Abstract: One or more switches in an occupancy sensor are enabled. When a switch is enabled, a reduction timer measuring a reduction time delay is initiated when an occupancy condition is detected by an occupancy sensor. In addition, one or more outputs controlled by the reduction timer are activated so that a signal is sent to a control system to notify the control systems of the occupancy condition. When the reduction time delay expires, the outputs of the occupancy sensor that are controlled by the reduction timer are deactivated, and so the outputs cease sending the signal to the control system. As a result, the control systems initiate their own internal time delays sooner.

    Abstract: A device for operating a relay to selectively provide power from a power supply to a load. The device determines an activation switching point for activating the relay such that inrush current resulting from the activation is minimal. The device also determines a deactivation switching point for deactivating the relay such that backrush current is minimal. The switching points are determined with respect to a voltage waveform of the supply power. The device varies the timing of the operation of the relay with respect to the voltage waveform and monitors the inrush or backrush current resulting from each timing until a minimum inrush or backrush current is found. The device stores these times in memory for subsequent operation of the relay. To further reduce inrush and backrush currents associated with inductive loads, the device activates and deactivate the relay on opposite half cycles.

    Abstract: A lighting device for illumination, data communication, and occupancy detection includes a processor and a transmitter circuit that is configured to generate a first electrical signal. During a first time duration, the first electrical signal is a carrier signal having a first frequency, and during a second time duration, the first electrical signal is a data encoded signal. The lighting device further includes a light source configured to emit a first visible light based on the first electrical signal. The lighting device also includes a receiver configured to receive a second visible light. The processor is configured to detect a motion in a monitored area based on the second visible light.

    Abstract: A luminaire can comprise a system that automatically adjusts light output from the luminaire to control light level in an illuminated area. The system can increase light output if the light level in the area falls below a target light level or decrease light output if the light level in the area rises above the target. For example, when the area is illuminated by a combination of sunlight and luminaire light, the light level can be maintained at the target level by gradually decreasing light output as the sunlight contribution increases in the morning and by gradually increasing light output as the sunlight contribution decreases in the evening. The system adjustments can take into consideration whether the light level is offset from the target due to a change in the target or a short-term fluctuation that may be due to a cloud temporarily blocking the sun.

    Abstract translation: 照明器可以包括自动调节来自照明器的光输出以控制照明区域中的光线的系统。 如果该区域的光线水平降低到目标光照水平以下，则该系统可以增加光输出，或者如果该区域中的光线水平升高到目标点以上，则可以减少光输出。 例如，当通过太阳光和照明灯的组合来照亮该区域时，通过逐渐降低光输出，当阳光的贡献在早晨增加时逐渐减小，并且通过逐渐增加光输出作为阳光的贡献，能够将光水平维持在目标水平 晚上减少 系统调整可以考虑到由于目标的变化导致的光水平是否偏离目标，或者由于云临时阻挡太阳而引起的短期波动。
