Abstract: An occupancy sensor having a replaceable cover with a convenient adjustment and installation scheme is disclosed herein. More particularly, a single or multi-technology occupancy sensor, assembled inside a semi-spherical shaped enclosure includes a replaceable cover with a convenient adjustment and installation scheme. This sensor design enables the sensor to be rotated after installation to obtain a desired coverage patterns. Specifically, the housing for the occupancy sensor includes a front cover having a lens assembly, a base assembly, a harmonic wheel, and a back cover. The front cover couples to the base assembly such that tool-less, manual access is available through the manually removable cover assembly to adjust several features of the sensor. The harmonic wheel enables the front cover, which includes the lens to swivel from zero to 359 degrees relative to the back cover anytime after installation.

Abstract: A sensor mounting mechanism that includes a base member adapted to be mounted to a structure and a base neck having a first end and a second end where the first end is adapted to be coupled to a sensor with a ball-socket coupling and the second end is coupled to the base member with a rotating coupling. The mounting mechanism provides fine and coarse adjustment means for adjusting the scanning area of the sensor such as an PIR occupancy sensor without the use of a tool. The sensor includes a detachable lens holder for easy replacement of the lens.

Abstract: A light control system having a full range of dimming for smart-glass by providing an interface between an off-the-shelf dimmer and a electrochromic glass device is disclosed herein. The light control system or electrochromic glass control device acts as an interface that converts an asymmetric alternating current (AC) power signal from the dimmer device into a symmetric, amplitude controlled AC output signal for controlling the tint of the smart-glass device. The electrochromic glass control device includes a powerline interface circuit that receives the asymmetric AC power signal from the dimmer. A controller connects to the powerline interface circuit to generate a control signal responsive to the asymmetric AC power signal. Connecting between the dimmer and the controller, an output stage generates the symmetrical AC output signal responsive to the control signal to control the electrochromic glass device.
