Abstract: A passive infrared motion detection sensor that includes a Fresnel focusing arrangement that creates at least a first infrared sensing region, a second infrared sensing region, and a third infrared sensing region, in which target detection in one or more infrared sensing regions is weighted to be distinguishable from target detection in remaining infrared sensing regions. The Fresnel focusing arrangement creates the weighted infrared sensing regions using a lenslet region, an optically opaque region and a plurality of extruded cylindrical lenslets that extend across a portion of both the lenslet region and the optically opaque region. The signal detection in at least the second weighted infrared sensing region, for example, an infrared sensing range between 6 and 10 feet, is weighted to easily distinguish between a pet within the second infrared sensing range and a person at any infrared sensing range.

Abstract: A hardware product for creating a light ring and a dead front effect. The product may include a housing with an opening. The hardware product may also include a button positioned within the opening and configured to be depressed by a user. The button is constructed using a two-part molding process and includes a first shot and a second shot. The first shot is configured to disperse light around the perimeter shape of the opening. The second shot is constructed from an optically opaque or semi-opaque material A single light-emitting component electrically coupled to the circuit board provides light for creating the light ring.

Abstract: Systems and techniques are provided for presence and directional motion detection. Signals may be received from a sensor positioned in a structure. An indication of directional motion may be generated based on the signals from the sensor. The indication of directional motion may be generated without using signals from additional sensors. A control signal for a device in the structure may be generated in response to the indication of directional motion. The control signal may be sent to the device in the structure to be implemented by the device.
