Title: Bus arbitrators for common local oscillators in cellular radiotelephone base stations
Inventor: FUGARO ANTHONY SALVATORE
IPC: H04B1/40
Filed: 1998-04-02
Abstract: A transceiver board for use in a cellular radiotelephone base station comprises a first cellular radio transceiver including a first controller that controls the operation of the first transceiver, a second cellular radio transceiver including a second controller that controls the operation of the second transceiver, common local oscillator that generates a tuning signal used by the first and second transceivers for tuning a radio signal, and an arbitrator that is connected to the first and second controllers and that determines which of the first and second controllers communicates with the common local oscillator. Preferably, the arbitrator is implemented by a programmable device such as a programmable logic device (PLD) that monitors the first and second controllers to determine which controller attempts to communicate with the common local oscillator first so that that controller is allowed to communicate with a common local oscillator to the exclusion of the other controller. Alternatively, the arbitrator can be implemented by a programmable device that monitors the first and second controller and a tristate buffer that is connected to the programmable device and that connects either the first or second controller to the common local oscillator as controlled by the programmable device.

Abstract: A protective device for excess current utilizes a fuse that incorporates a printed circuit board. The printed circuit board has a trace on one side which is of a desired width, length, and thickness of material for opening if excess current for a selected duration of time is reached. The printed circuit board is mounted in an insulated housing. The lower side of the substrate may also have a conductive layer connected to the housing or ground. The printed circuit board and overvoltage protector may be tailored for impedance matching. An excess voltage protector may be incorporated with the printed circuit board for conducting to ground if excessive voltage is encountered. The housing has two terminals which are connected to the printed circuit board and voltage protector. These terminals may be conventional coaxial cable connectors.

Title: Headrail and control system for powered coverings for architectural openings
Inventor: ANDERSON RICHARD N
IPC: E06B9/323
Filed: 2000-01-11
Abstract: A headrail designed for powered coverings for architectural openings comprises a housing defining an interior that conveniently hides a battery holder, a signal-receiving system, and an electric motor used to adjust the configuration of the covering. The headrail also hides improved hardware for mounting the motor and, in the case of coverings comprising tiltable elements, improved hardware for mounting a tilt rod. Additionally, in the case of coverings comprising tiltable elements, the headrail hides improved hardware for adjustably attaching the tiltable elements to the tilt rod in a manner that prevents, over-rotation of the tiltable elements. The battery holder may comprise a battery magazine or a battery carrier removably mounted in the headrail housing. The batteries may be inserted into or extracted from the battery holder through an opening in a bottom wall of the headrail housing. A swingably mounted trap door may selectively cover or uncover the opening. The battery carrier slidingly engages, through the opening in the bottom of the headrail housing, a battery carrier housing that is mounted within the headrail housing. The signal- receiving system includes an exposed signal receiver for receipt of remote-control signals. The present invention also provides a tilt control system with an inexpensive and effective clutch to prevent over-winding of cords onto a control shaft (e.g., a tilt rod) used to control tiltable elements of the covering. The preferred tilt control system also minimizes torque on the motor or other mechanism used to drive the control shaft.

Patent CA-2317899-A1 (CA)
Inventor: MILBAR MAREK
IPC: H04H20/00
Filed: 2000-09-07
Abstract: A method and apparatus are disclosed for frequency offset estimation in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The frequency offset estimation algorithm first determines the coarse frequency offset, in terms of integer number of OFDM bin separations between an actual and measured location of a correlated peak, followed by estimation and tracking of the partial (residual) offset in a continuous fashion. A frame is correlated at a first frequency, and then the frequency is shifted by a predefined amount, such as half of the inter-bin frequency amount, .DELTA.f, before correlating again. The measurement with the highest peak of the plurality of frequency values is utilized to obtain the course frequency offset estimate.  The partial frequency offset estimation algorithm utilizes phase information contained in reference frequency points in the frequency domain. The phase rotation of the reference vector is proportional to the frequency error, and the frequency error is extracted and filtered in the time domain. The initial partial frequency offset estimation is corrected and used for continuous frequency tracking. Following the course frequency offset estimation, the unmodulated pilot bins (and all other bins), are within at least half the of the OFDM bin separation. In the presence of a frequency offset, the complex bins start rotating. The rate of the rotation is a function of the extent of the partial frequency offset. The change in phase from one frame to the next is proportional to the rate of rotation, and the sign of the rotation indicates the direction of the shift.

Abstract: On décrit un système de traitement de données qui comprend un panneau arrière auquel est raccordée une pluralité de composants LC au moyen d'une pluralité de connecteurs. Un ensemble de points de connexion communs (41) est relié électriquement aux connecteurs par des tracés individuels entre chaque point de connexion commun et les broches correspondantes des connecteurs. L'inductance des tracés les plus longs est réduite par fusion des tracés à proximité d'une partie centrale du panneau arrière pour former une zone conductrice (45) s'étendant jusqu'à au moins un connecteur (42, 43), de part et d'autre des points de connexion communs, ce qui réduit électriquement les tracés les plus longs. L'inductance est davantage réduite par agrandissement des tracés les plus longs, lesquels sont plus larges que les tracés les plus courts. On diminue ainsi les différences entre les composants LC associés à chaque tracé et, partant, les écarts de retard entre les tracés.
