Abstract: An adjustable box extender allows an electrical device to be aligned with a dry wall face. The adjustable box extender includes a fixed ring attached to an electrical box and an adjustable ring adjustably attached to the fixed ring. The adjustable ring includes rectangular top and bottom open back pockets. Rectangular blocks reside inside each pocket. Adjusting screws are held by the adjustable ring with screw heads exposed on the face of the adjustable ring, neither advancing nor retreating with respect to the adjustable ring, and free to rotate with respect to the adjustable ring. The screws engage threads in the blocks and advance and retreat the block out of and into the pockets when the screws are turned, thereby extending the adjustable ring away from the fixed ring to adjust for dry wall thickness. Electrical device screws sandwich the adjustable ring between the electrical device and the fixed ring.

Abstract: Disclosed is an electronic circuit assembled onto a miniature printed circuit board and assembled into an AC plug body such that the AC mains connect to terminals on or connected to the printed circuit board. The circuit contains a filtered power supply, microcontroller, and external interface, such that the plug may be connected to a special interface connector in order for data to be exchanged with a PC or computer or other programmer/reader device. A current sensor is employed and a voltage sensor is also employed. From the combined readings from the voltage sensor and the current sensor, the embedded program running on the microcontroller can determine the power being consumed by the loading device.

Abstract: An electronic audible warning device (10), which includes a power source (18), a motion detector (401), a pleasant tone generator (100, Q1, Q3), a loud piercing tone generator (100, Q1, Q2) and a remote push button activation switch (19) is disclosed. Signaling device (10) provides two distinct features, each responsive to remote activation switch (19). A single depression on push button switch (19) will sound an unobtrusive, pleasant sounding two second pulsating warning tone. Two consecutive pushes on push button (19) will sound an attention-getting pulsating signal, similar to the backup beeper on commercial trucks, which will continue to sound until button (19) is pressed again. An additional feature is provided which is responsive to a motion detector (401). Here, a loud, piercing tone is sounded whenever a bicycle (1) or similarly attached article is moved. The alarm is activated and deactivated via an electrical key switch (402) which is installed directly in main housing (11).
