Title: Apparatus for regulating an elevator motor
Inventor: SUUR-ASKOLA SEPPO
IPC: H02P27/04
Filed: 1995-05-10
Abstract: The invention relates to an apparatus for regulating the speed of an a.c. elevator motor (10) by means of a frequency converter (8) consisting of a rectifier bridge (4) and an inverter bridge (4). The frequency of the frequency converter is adjusted until it corresponds to a frequency reference (fref) corresponding to the speed reference (vref'vref') of the motor. The velocity of the motor (vreal) is measured to form a speed feedback signal.

Patent AU-2615101-A (AU)
Title: Manual tool changing apparatus
Inventor: PATEL HIMAT
IPC: B25B33/00
Filed: 2000-10-20
Abstract: A manually operated apparatus for removal and insertion of a tool holder to and from a tool pocket of a magazine includes two components-a multi-function insertion/removal tool, and a pivot bracket. The multi-function tool generally comprises an elongated bar having a tool holder removal element at one end and an insertion element at the opposite end. The removal element can constitute a known pry tool having a fork portion configured to facilitate insertion between the rim of the tool pocket and the underside of the circumferential flange of the tool holder. The insertion element of the multi-function insertion/removal tool comprises a pivot block and a pressure plate. The pivot block includes a pivot pin projecting therefrom that is configured for pivoting engagement within a channel defined in the pivot bracket. The pivot bracket is mounted to the housing of the tool magazine at a manually accessible location relative to the tool pockets with the open end of the channel facing away from the tool pocket. When the pivot pin of the insertion/removal tool is disposed within the channel of the pivot bracket, the pressure plate is situated over a portion of the circumferential flange of the tool holder when the holder is loosely disposed within the tool pocket. The elongated bar of the tool can be used as a lever arm to pivot the tool about the fulcrum point defined by the pivot pin and pivot bracket. As the elongated bar is manipulated, the pressure plate is pivoted downward, bearing against the circumferential flange of the tool holder with sufficient force to overcome the pocket spring force operating against the knob of the tool holder.

Title: Method, system and device for transferring, by electromagnetic linkage, data between readers and nomadic objects
Inventor: LEVERNE JEAN-CLAUDE
IPC: G06K7/00
Filed: 1999-03-11
Abstract: The invention concerns methods, systems and devices for transferring, by electromagnetic linkage, data between universal readers and badges with different communication protocols. The universal reader searches for the nomadic objects by emitting a scanning signal of modulation modes. Each nomadic object, receiving the scanning signal, produces an echo signal, according to its own particular protocol. The universal reader analyzes each echo signal and deduces therefrom the specific protocol applied by the nomadic object. The universal reader inserts in universal reader inserts in conformity with the specific protocol, the messages to be transmitted in the reader frames interpretable by the nomadic object.
Patent AU-2957497-A (AU)
Title: Method and apparatus for point-to-multipoint data communication with arq
Inventor: ROBINSON WILLIAM NEIL
IPC: H04L1/00
Filed: 1997-05-19
Abstract: The method involves delivering data to multiple wireless destinations by the issuing of a negative acknowledge message (418) from a receiving terminal upon detecting a second outstanding block error (416). The transmitting terminal sends an error correction block for all the blocks up to but not including the block with the second detected error, which increases the throughput. Each receiver is independent of the other receivers and decodes the incoming blocks. Every receiver performs the error detection function on every received block and detects whether or not the block has been received correctly.

Title: Method and apparatus for providing redundant radio coverage within a cellular communication system
Inventor: GILMORE ROBERT P
IPC: H04B1/74
Filed: 1995-11-28
Abstract: A system and method for using a sectored antenna arrangement within a cellular base station to provide redundant coverage within the surrounding cell is disclosed herein. An antenna feed network connects elements of the sectored antenna arrangement to a set of communication transceivers, wherein the feed network includes a combiner array for combining selected ones of the antenna beams upon failure of one of the communication transceivers. A switch network serves to provide the resultant combined beam to an operative one of the communication transceivers. Alternately, the sectored antenna arrangement includes an antenna array having a plurality of switchable antenna elements, each connected to one of the communication transceivers. The switchable antenna elements project a set of variable-width antenna beams over the plurality of cell sectors. Upon one of the communication transceivers becoming inoperative, an antenna control network operates to adjust beam width of a selected one of the variable-width antenna beams by switching configuration of an associated one of the switchable antenna elements. In another approach each antenna within a primary array is disposed to project a beam over a single sector, while each element within a redundant array is designed to encompass a pair of adjacent sectors. Upon one of the transceivers becoming inoperative, a transceiver nominally assigned to cover a sector neighboring the failed sector is connected to the element within the redundant array encompassing both the failed and neighboring sectors.
