Abstract: A power outage socket device that may be installed on a variety of lamps or light fixtures. The bottom of the device has a male connector adapted to be inserted into the light socket on the lamp or light fixture, in place of the light bulb. A female socket adapted to receive the light bulb is located on the top of the device. The male connector may be recessed. When power is interrupted, emergency power is provided to one or more emergency light sources on the device to provide light. Emergency power is provided by one or more batteries, which may be rechargeable. The device also may include means for connecting a lamp harp, or for allowing a lamp harp to pass through the device. A photoelectric light sensor may be used to detect ambient light and control whether emergency light is provided when normal power is interrupted.

Abstract: A wireless timer system (10) is shown including a master unit (12) and multiple remote modules (13). The master unit communicates with the slave units through a RF signal. The master unit includes a control circuit for controlling the activation of the remote modules during at least one designated activation time period having a commencement time and a termination time. The designated activation time period including a plurality of on/off cycles. The control circuit changes the selection of which remote module to activate first upon each occurrence of reaching the designated activation time period. The control circuit may also include a variable time range associated with the activation time period. The control circuit may change the commencement time each day to a time within the variable time range from the commencement time.
