Title: Telephone with a receiver arousing bone-conduction and air-conduction hearing
Inventor: KANG KYEONG OK
IPC: H04M1/03
Filed: 1997-11-04
Abstract: A telephone with a receiver arousing bone-conduction and air-conduction hearing converts an input electric voice signal into vibration and acoustic signals. Since a conventional telephone has a receiver for only air-conduction hearing, a hearing impaired person cannot use the conventional telephone. In case of a bone-conduction telephone using a bone-conduction vibrator as a receiver, this vibrator is only used for bone-conduction hearing, so that an additional telephone is needed when the ordinary person and the hearing impaired person live in the same place. The telephone with a receiver arousing bone-conduction and air-conduction hearing uses a vibrator of smoothly arousing bone-conduction and air-conduction hearing as a receiver, is capable of hearing a vibration signal through bone-conduction hearing as well as an acoustic signal through air-conduction hearing, makes a hearing-impaired person with conductive hearing loss and an old person who has difficulty in air-conduction hearing use bone-conduction hearing, and makes an ordinary person having a normal sense of hearing use either bone-conduction hearing in a noise environment or air-conduction hearing in a normal environment.

Title: Theft resistant lamp assembly mounting bracket
Inventor: O'NEAL CHARLES P
IPC: F21V15/00
Filed: 2000-03-07
Abstract: The present invention comprises a mounting bracket that may be permanently mounted to a vehicle, such as by riveting. The mounting bracket includes at least one deflectable tab that is deflected away from a main plane of the bracket when the lamp assembly is pressed against it. The lamp assembly includes an extending surface which interacts with the mounting bracket tab in order to deflect the tab. Subsequent rotation of the lamp assembly in a clockwise direction causes the lamp extending surface to move under the mounting bracket, allowing the deflected tab to return to its quiescent position. Any attempt to remove the lamp assembly from the mounting bracket by turning the lamp assembly in a counter-clockwise direction is prevented by interaction between the lamp extending surface and the now non-deflected mounting bracket tab. Theft of the lamp assembly is thereby prevented.

Patent CA-2311337-A1 (CA)
Title: Cell identification based on distance
Inventor: TRZECIAK STEPHAN
IPC: H04W16/00
Filed: 1998-11-17
Abstract: The present invention relates generally to the problem of determining the identity of a cell for e.g. cell handoff or automatic frequency planning, and more particularly to the problem of determining the true identity of a cell when only the transmission frequency and a non-unique identity code is known.  A candidate list is created for each cell. This candidate list is created based on a function of various elements e.g. distance, transmission power, cell type, and antenna placement. The cells are then ranked on the candidate list based on this function. When a particular frequency/code combination is detected, the candidate list is then consulted, and the highest ranking cell with the same frequency/code combination is chosen as being the signal source.  In an alternative embodiment the neighbor cell list is used to create the candidate list. If there are no matches on this list for the detected frequency/code combination, then the neighbors of the cells on the candidate list are also added to the candidate list which is then checked for a match.
