20090278479 | NETWORKED, WIRELESS LIGHTING CONTROL SYSTEM WITH DISTRIBUTED INTELLIGENCE - A programmable lighting control system integrates time-based, sensor-based, and manual control of lighting and other loads. The system includes one or more groups of controlled lighting areas, which may be, for example, floors of a building. Each group may have one or more lighting zones, which may be, for example, individual rooms or offices on a building floor. Each lighting zone includes occupancy and/or daylight sensors that may be wirelessly coupled to a gateway of the group. Each gateway is coupled to a network, such as, for example, a local area network (LAN). Control software, residing on a computer (e.g., a personal computer or a server) coupled to the network and accessible via the network, remotely communicates with and controls the lighting zones either individually, groupwise, or globally. Each lighting zone can also be locally controlled at the gateway and can function independently of the control software and the gateway. | 11-12-2009 |
20110025497 | OCCUPANCY SENSORS PROGRAMMED TO DETERMINE LOSS OF LAMP LIFE AS LAMP IS USED - Programmable occupancy sensors that control the on/off operation of a fluorescent lamp automatically determine loss of lamp life as the lamp is used. The programmable occupancy sensors can provide lamp life status and can automatically alert a user when a lamp is nearing its end of life and should be replaced. The occupancy sensors are also programmable to automatically maximize lamp life and energy savings by selecting an optimal time delay from among a number of selectable time delays at which to operate the sensor. The selection is based on an occupancy pattern sensed by the sensor over a given period of time. The optimal time delay, which prevents the lamp from turning off immediately after last sensing occupancy, extends lamp life by limiting the number of lamp off/on transitions, which shortens lamp life, in view of overall energy usage and lamp usage. | 02-03-2011 |
