International Classification:

H05B 37/02

US Classification:

315307, 315312, 315360, 315362

Abstract:

Methods, systems and apparatuses for controlling a light through an automatic mode and a bypass mode are disclosed. One method includes receiving physical signaling. Detection of a predetermined sequence of the physical signaling is used to determine whether to control the light in the automatic mode or the bypass mode. The automatic mode provides network control of the light, and the bypass mode bypasses the network control of the light. One lighting system includes a light, a sensor for receiving and sensing the physical signaling, and a controller detecting a predetermined sequence of the physical signaling. Detection of a predetermined sequence of the physical signaling is used to determine whether to control the light in the automatic mode or the bypass mode. The automatic mode provides network control of the light, and the bypass mode bypasses the network control of the light.

US Classification:

315312, 356 407, 356 72

Abstract:

An apparatus and method of deducing building floor plan information are disclosed. One method includes changing an intensity of light generated from a plurality of lights within a building. A plurality of light sensors senses an intensity of light received from at least one of the plurality of lights. A distance between at least one light sensor and at least one of the plurality of lights is estimated based on the sensed intensity of light.

Assignee:

ENLIGHTED, INC. - Sunnyvale CA

International Classification:

G05B 15/02

US Classification:

700275

Abstract:

Methods, apparatuses and systems of building control, are disclosed. One system includes a plurality of building fixtures and at least one sensor interfaced with at least one of the plurality of building fixtures. Further, each building fixture includes a communication port and a controller. For this embodiment, each controller is configured to independently control at least one of an environmental load or a security device, either receive or help designate the building fixture as belonging to a logical group of building fixtures, and share at least one of sensor or state information with other building fixtures within the logical group of building fixtures, through the communication port.

US Classification:

315153, 315307, 315297, 315158

Abstract:

Apparatuses, methods and systems for controlling a luminaire are disclosed. One embodiment includes a lighting control sub-system. The lighting control sub-system includes a luminaire, a controller coupled to the luminaire, and a sensor coupled to the controller. The sensor generates a sensed input. The lighting control sub-system further includes a communication interface, wherein the communication interface couples the controller to an external device. The controller is operative to control a light output of the luminaire based at least in part on the sensed input, and to communicate at least one of state or sensed information to the external device.

International Classification:

H05B 37/02

US Classification:

315 86

Abstract:

Methods, apparatuses and systems of an intelligent light controller controlling a light, are disclosed. One method includes interpreting a switch from a normal power supply to an emergency power supply. Upon interpreting the switch from the normal power supply to the emergency power supply, the intelligent light controller controllably powers the light for a predetermined period of time. Further, the intelligent light controller executes an energy-savings behavior control of the light.

Appl. No.:

7/762533

Harry E. White - Newark CA

Assignee:

Raychem Corporation - Menlo Park CA

International Classification:

H01R 460

US Classification:

439204

Abstract:

An open end of a hollow member is sealed using a sealing member comprising a layer of sealant between two constraining layers. Force is applied to the sealing member to maintain the sealant in sealing contact with the inner walls of the hollow member. At least one of the constraining layers and/or the means of applying force is sufficiently resilient to accommodate volume changes of the sealant during temperature fluctuations and displacement of the sealant when a substrate is inserted into the hollow member through the sealing member. To facilitate insertion of the substrate through the sealing member, holes and/or slits may be provided in one or both of the constraining layers and/or through the sealant layer.
