Abstract: A system and method is disclosed for actively maintaining security of a premises. The method can include the operation of establishing a data link between a local security controller within the premises and a monitoring station located remote from the premises. A security data packet can be transmitted between the local security controller and the monitoring station at a predefined periodic rate. A check of the premises can be initiated if the monitoring station does not receive the security data packet within a predetermined time frame. Selected electronic neighborhood watch subscribers can be notified if the monitoring station does not receive the security data packet within the predetermined time frame.

Abstract: A dimmer for fluorescent lights utilizes a standard A.C. phase control at normal line A.C. frequencies to control the line power to the standard fluorescent light ballast and thereby control the illumination level of the light. During the "off" time of the A.C. line signal, a high frequency signal is applied to the ballast which supplies additional power through the ballast to the filament of the light but is substantially blocked by the ballast from the discharge portion of the light so does not substantially affect the illuminating output of the light.
