International Classification:

G01J 5/02

US Classification:

250342, 250353, 250DIG 1

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.

Filed:

Feb 15, 2007

Appl. No.:

11/675329

Inventors:

Yun Wu - Bayside NY, US

Assignee:

Leviton Manufacturing Co., Inc. - Melville NY

International Classification:

H01H 3/00
H01H 3/16

US Classification:

200 6172, 200 18, 323905

Abstract:

A dimmer switch includes a first switch for coupling to a power source, a second switch, a dimmer module, and a main actuator movable between an operational position and a disconnected position. The main actuator includes a first switch actuator and a second switch actuator. The first switch may be a normally-closed air-gap switch including a lever in contact with the first switch actuator. Movement of the main actuator between the operational position and the disconnected position is effective to open the switch. The main actuator is pivotally and slidably coupled to a frame. A coupling between the main actuator and the frame includes a pivot in a pivot holder; a partial cylindrical surface of the pivot is in contact with a surface of the pivot holder which includes a first portion having a partial cylindrical surface and a second portion having a ramp surface.

US Classification:

200330, 200 18, 200339

Abstract:

An electrical device controller is provided for controlling power to a load. The controller includes a housing having an open face and a plate having a unitary aperture secured to the housing and disposed over the open face. The controller further includes an electrical power controller component positioned within the housing for coupling to a power source and a load, a first actuator coupled to the electrical component, and an adjacent second actuator coupled to the electrical component. The first actuator has a movable user operable portion that is user accessible via the unitary aperture for controlling power ON/OFF to the load. The second actuator has a movable user operable portion that is user accessible via the unitary aperture for adjusting magnitude of power delivered to the load. The movement and position of the respective user operable portions of the first and second actuators are mutually independent.
