  • Patent number: 9958424
    Abstract: The present disclosure provides a method of identifying an airborne molecular contamination (AMC) leaking source in a fab. The method includes distributing a sensor in the fab, executing a forward computational fluid dynamics (CFD) simulation of an air flow in the fab, setting an inversed modeling of the forward CFD simulation of the air flow in the fab, building up a database of a spatial response probability distribution matrix of the sensor using an AMC measurement data in the fab, and identifying the AMC leaking source using the database of the spatial response probability distribution matrix of the sensor.

  • Patent number: 8786137
    Abstract: A digital wiring device including a user interface panel, a digital display, and a paddle including a transparent portion to reveal the digital display and an opaque portion to cover the user interface panel. The paddle rotates from a first closed position to a second open position. A digital “schedule-at-a-glance” may be provided so that a user can quickly assess a schedule of events. The digital wiring device may include a back light to illuminate the digital display. The paddle may be operatively associated with the back light. A battery may provide an electrical current to power the digital wiring device in a battery backup mode, and the back light may be disabled based on the mode. The user interface panel may be used to schedule events or otherwise configure the digital wiring device.

  • Patent number: 7985937
    Abstract: A switching device includes a paddle actuator biased to a rest position and configured to pivot relative to a housing to a depressed position to engage an air-gap switch disposed within the housing. The air-gap switch is configured to change a first state of a load connected to the switching device upon engagement by the paddle actuator. The paddle actuator is defined by a pair of opposing long sides and a pair of opposing short sides and has at least one slot defined therein parallel to the pair of opposing short sides thereof and centrally disposed between the pair of opposing long sides thereof. A rocker actuator is disposed in the at least one slot defined in the paddle actuator and is configured to pivot relative thereto to engage at least one switch. The at least one switch is configured to change a second state of the load connected to the switching device upon engagement by the rocker actuator.

  • Publication number: 20100101924
    Abstract: A switching device includes a housing and a paddle actuator operably coupled to a front face of the housing and adapted to control a state of a load. The paddle actuator has a pair of opposing long sides and short sides and is configured to pivot about a hinge disposed proximate to one of the short sides of the paddle actuator. At least one component is disposed adjacent to the short side of the paddle actuator that is disposed proximate to the hinge and is configured to sense at least one condition. A control element is configured to control at least one of a sensing range and a sensitivity of the at least one component. The paddle actuator occupies at least 50% of the front face of the housing and the at least one component substantially occupies the remainder of the front face.
