Title: Frequency hopping spread spectrum communications system
Inventor: SHUEY KENNETH C
IPC: H04B1/7156
Filed: 2002-12-20
Granted: 2009-02-10
Abstract: The present invention is directed to a frequency hopping spread spectrum transceiver. The transceiver includes a microcontroller (110); a transmitter having a voltage controlled oscillator (122), a direct digital synthesizer (124), and a power amplifier (144); and a receiver having an amplifier (146), a mixer, an IF amplifier (132), a demodulator (134), and a data slicer (138).  When transmitting, the transmitter communicates a preamble over a predetermined number of preamble channels, and thereafter communicate groups of data bytes that each comprise a subset of the data message over a predetermined sequence of data channels. When receiving, the receiver investigates the predetermined number of preamble channels to search for the preamble, each of the predetermined number of preamble channels being associated with a predetermined number of data channels in each sequence of data channels. A number of bytes that comprises each group of data bytes is determined in accordance with a number of channels in the sequence of data channels and the predetermined number of times each byte of the data message is to be transmitted.

Abstract: An apparatus for controlling the barking of a dog through application of a spray deterrent, or spray control bark collar (10). The spray control bark collar (10) administers a dose of a pressurized substance in response to the barking of the dog. The spray control bark collar (10) detects the barking of the dog through the measuring of vibrations produced by the dog. In addition, the spray control bark collar (10) delivers successively larger doses of the spray deterrent to the dog to deter the dog from further barking should the dog fail to respond to previous deterrent attempts. Finally, the spray control bark collar (10) monitors the usage of the spray deterrents to gauge the amount of the deterrent substance remaining in the deterrent substance reservoir (112).

Abstract: A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description. An alerting mechanism scans all content in real-time and can be configured to notify users by various means upon the occurrence of a specified search criteria in the video stream. The system is preferably designed to be used on publicly available broadcast video content, but can also be used to catalog private video, such as conference speeches or audio-only content such as radio broadcasts.

Title: Method for fixing a miniaturized component to a carrier plate
Inventor: WUERSCH ALAIN
IPC: H05K13/04
Filed: 2003-11-28
Granted: 2012-07-10
Abstract: The invention relates to a method, a device and a system for fixing a miniaturized component (3a) - especially carrying or containing at least one optical element - to a carrier plate (4a) in a highly-precise manner, by means of a soldered joint, a welded joint or an adhesive joint. Said component (3a) is positioned above the carrier plate (4a) in relation to outer reference points by means of a gripper (la) pertaining to a robot station (2a). A joint (6a) is then created between the component (3a) and the carrier plate (4a), the joint seam (6a) hardening under contraction between the component (3a) and the carrier plate (4a), thus exerting a vertical tractive force on the gripper (la) holding the component (3a). At the same time as the contraction, the gripper (la) is vertically displaced towards the carrier plate (4a) in a controlled or regulated manner, optionally up to a defined nominal position, and actively yields to the contraction such that the creation of high tensions is largely avoided and the position does not change when the component (3a) is detached from the gripper (1a). The invention also relates to a gripper (1a) for using in said method.

Title: Electric generator for vehicle producing dual output voltages
Inventor: KUSASE SHIN
IPC: H02K11/04
Filed: 2005-09-16
Granted: 2011-01-04
Abstract: An electric generator according to the invention includes a rotor, a stator, a rectifier, and a regulator. The rotor includes a field winding. The stator includes a first and a second three-phase winding, each of which has three output terminals corresponding to respective phases. The rectifier has a specially designed three-layer structure, to which the output terminals of the first and second three-phase windings are separately connected, and works to output two different DC voltages through rectifying outputs of the two three-phase windings. The regulator works to regulate the output voltages through controlling a field current supply to the field winding. With such a structure, the electric generator can reliably produce two different output voltages at the same time. Moreover, compared to existing electric generators producing dual output voltages, the structure of the electric generator is much simplified, thus reducing manufacturing cost and the internal impedance of the electric generator.

Abstract: L'invention concerne des oligonucléotides comprenant un système de commutation moléculaire pouvant exister dans une position "ouverte" ou "fermée". La partie de commutation moléculaire de la sonde est particulièrement sensible à l'identité de séquences complémentaires du système de commutation moléculaire. Les oligonucléotides contenant un système de commutation moléculaire sont applicables à tous les types de processus d'hybridation. Du fait de la sensibilité du domaine de commutation de l'oligonucléotide, les sondes contenant un système de commutation moléculaire sont particulièrement utiles dans l'identification de mésappariements ponctuels uniques. Plus particulièrement, une partie, et non la totalité, de l'oligonucléotide devient libérée d'une cible mésappariée. L'invention concerne également des méthodes d'utilisation de ces oligonucléotides pour des réactifs de recherche et des diagnostics cliniques. Par exemple, un oligonucléotide peut comprendre un premier domaine hybridable, un deuxième domaine de pontage et un troisième domaine de liaison.
