Title: Energy management control system for fluorescent lighting
Inventor: BAKER JAMES A
IPC: H05B37/02
Filed: 1995-01-16
Abstract: An energy saving lighting control system for operating fluorescent light fixtures is provided with means for controlling the light level according to the light required for the task being done in the area.      Ambient light available from sources outside of the controlled area such as daylight can be harvested to reduce the amount of artificial lighting required. A method of providing sensor inputs to detect occupancy in the controlled area provides control signals to the lighting control system which are used to reduce the light level or turn light fixtures off at times when the area is not occupied. A method of providing a central control of the operation of the lighting system can provide time-of-day scheduling, can provide minimum and maximum lighting levels, and can provide calibration and set-points for response times to various sensor inputs. In order to minimize the installation cost of the lighting control system, the system is provided with components that can be controlled using signals carried along the power conductors that provide primary operative power to the lighting fixtures. Special circuitry in the ballasts for fluorescent lamps provides a starting sequence and operating conditions that maximize the life of the lamps which therefore minimizes maintenance costs.

Patent CA-2153540-A1 (CA)
Title: Overlapping non-interactive radio patch method
IPC: H04W84/08
Filed: 1995-07-10
Abstract: A method of managing (150) an overlapping radio patch which allows a audio channel to be involved in multiple patches which are established l at different dispatch positions. The method prevents interaction between channels that are not part of the same radio patch by maintaining dynamic profiles of channel assignments  (153) and channel patches (155). Channel activity is tracked (157) and a connection instance count (CIC) is determined using the assignment and patch profiles as well as the channel activity. Audio connections are then managed (161) using the corresponding CIC's to dynamically switch connections. This ensures the connections are in place only when needed thereby avoiding any latent connections which would contend for network resources. The invention allows for the implementation of a composite channel concept which improves the overall capability of radio dispatch services in a multi-channel, multi-dispatcher environment.
