Abstract: A simple, low-cost method and apparatus for supporting a lighting fixture, motion detector or the like while it is being electrically connected and mounted on a junction box in a side wall or ceiling. A disposable support link is provided for supporting the weight of the fixture during installation. The support link is easily attachable to the junction box and to the fixture without the need for tools, and can even be attached with only one hand. When the electrical connections are completed and the fixture is ready to be mounted on the junction box, the support link may simply be left in place in the junction box or in one embodiment may be removed with one hand as easily as it was attached. The support link is secured to the back side of the fixture in a position that will face the junction box when the fixture is in its installed configuration on the junction box. The other end of the support link is formed to be attachable to the junction box, either directly or through additional mounting hardware such as a cross bar across the face of the junction box. The junction box or cross bar is an otherwise conventional junction box or cross bar that has been provided with a means by which the support link may be readily attached at the time of installation with a simple hand motion without any tools. With this apparatus an installer begins installing a fixture first by attaching the support link so that the fixture hangs from the junction box firmly supported by the support link. The installer then has both hands free to make the electrical connections. The support link may then be removed or, since it is flexible and occupies almost no space, may be stuffed into the junction box along with the electrical leads from the fixture as the fixture is mounted on the junction box.

Abstract: A two-sided passive infrared integrated-circuit sensor package for use in infrared motion detectors as well as other infrared sensing applications. The integrated-circuit sensor package has a casing with viewing windows transmissive to infrared radiation on opposite sides. Infrared sensing elements are mounted within the integrated circuit package so that both sides of the sensing elements are able to receive infrared radiation through the viewing windows from the areas in front of and behind the integrated-circuit package. By this simple mechanical change in the package and sensing element mounting, the area of sensitivity of the sensor is effectively doubled with no change in the electronic design of the circuit and with no increase in the number or size of the infrared-sensitive sensing elements within the IC package.

Abstract: A passive infra-red motion detector with wide field of view extending to greater than 180 degrees that can be achieved in a cost-effective manner using a single sensor. The motion detector includes a planar infra-red sensor and two or more infrared-reflecting faces which are positioned close to and overlying at least a portion of the sensor. The reflecting faces are configured so that their ends proximal to the sensor overlie the sensor at its midportion and the faces extend from the midportion in different directions away from one another to reflect radiation to the sensor from different sides of the sensor. In one embodiment the reflecting faces form a generally prismoidal shape. In another embodiment the proximal ends of a pair of faces are displaced laterally from one another over the sensor so that the overlying faces obstruct a portion of the sensor and leave a portion unobstructed to form a checkerboard pattern of obstructed and unobstructed regions. The reflecting faces are positioned close to the sensor with their proximal ends spaced apart from the sensor at most a distance comparable to a characteristic transverse dimension of the sensor. Because of the close proximity of the mirror to the sensor, the area of the reflecting surfaces need not be very large and may be made comparatively small. The mirror surfaces deflect infrared energy from a suitable focusing means onto the sensor from a plurality of zones so as to extend the lateral extremities of the motion detector field of view. Configured in this way, motion detectors may be provided with viewing angles at least up to 220 degrees using a single sensor. The reflecting faces may be formed together with a base from a single member, which also is shaped to receive and hold an integrated-circuit sensor package. The unitary reflecting head and base portion can be mounted directly on a printed circuit board and the reflecting faces are automatically aligned correctly over the sensor.
