Abstract: A novel illumination device is provided which is small, inexpensive, and conveniently plugs into a standard power outlet, thereby allowing easy installation and deinstallation by nontechnical consumers, and thereby allowing the security light to be easily moved to any wall outlet as security needs change. This illumination device includes a motion detector so that the illumination is provided only in the presence of one or more persons who would find the illumination beneficial. A photoelectric device is provided such that the security light is illuminated in response to motion only when there is an insufficient amount of ambient light available from other sources. In one embodiment, a vision restrictor is provided such that motion is detected only from a desired detection area. In one embodiment, a vision extender is utilized in order to optimize the field of view for the motion detector, making the device more useful in narrow hallways and other unique installations.

Abstract: A combination of fixed frequency audio tones and conventional dual tones (as generated by a DTMF telephone set), are used in the autoline control circuit of the invention. All tones are generated by the DTMF telephone set to systematically provide functions available to the subscriber without need for quad conductors in the in-house telephone line and mechanical disconnects. Low cost integration of the present invention into existing FCC tarriffed DTMF equipment and systems without adverse effects is a paramount requirement as the above-mentioned functions are carried out. Conventional jacks and plugs are used to place the parallel autoline circuit of the invention in parallel with the DTMF telephones and the conventional in-premises line connector.

Abstract: A submetering apparatus that includes a power supply unit, an apartment monitoring unit, a main meter monitoring unit, a power failure detection unit, a power failure protection unit, a main processing unit and a memory unit. The apparatus further includes a display unit, a modem unit, a terminal unit, a control switch unit and a memory module unit. These units interact to allow the apparatus to monitor furnace on-time for individual apartment units and to store that data until needed and to calculate appropriate billing statements.
