Title: High spectral purity digital waveform synthesizer
Inventor: HSU STEVE I
IPC: H03B21/04
Filed: 1994-06-23
Abstract: HIGH SPECTRAL PURITY DIGITAL WAVEFORM SYNTHESIZER                                       ABSTRACT A digital waveform synthesizer, using a direct digital synthesizer and a digitalfrequency divider. The direct digital synthesizer provides a digitally synthesized input frequency signal. An upconverter and frequency divider circuit upconverts and divides the synthesized input frequency signal to provide an divided synthesized frequency signal. An output upconverter circuit is coupled to the upconverter and divider circuit for providing an upconverted output frequency signal. A reference frequency generator is coupled to the direct digital synthesizer, to the upconverter and divider circuit, and to the output upconverter, for providing clock and frequency reference signals thereto. The waveform generator is coupled to the direct digital synthesizer for commanding a desired waveform. The frequency divider is used to improve the inherently poor spurious signal performance of the direct digital synthesizer. The digital waveform synthesizer provides fast switching, flexible and precisely defined frequency output signals. The digital waveform synthesizer may be used with any signal generator that requires high spectral purity and frequency precision, but requires relatively narrow signal bandwidth.

Title: Appareil et methode de synchronisation de stations de base dans un systeme de communication
Inventor: WALSH WILLIAM J
IPC: H04W92/00
Filed: 1993-09-22
Abstract: Un système de communication (105) utilise le système GPS afin de maintenir un degré de précision élevé de synchronisation des stations de base (115-116). Lorsque le signal GPS (106, 107 ou 108) est absent, le système de communication (105) utilise un signal de remplacement (110-113) tel qu'un signal WWVB, LORAN-C et MSF de manière à assurer la synchronisation redondante des stations de base (115-116). Pour atteindre le degré de précision de synchronisation assuré par le signal GPS (106-108), le système de communication (105) détermine les caractéristiques du signal de remplacement (110-113) en utilisant le signal GPS (106-108) lorsque le signal GPS (106-108) est présent. Lorsque le signal GPS (106-108) est absent, le signal de remplacement caractérisé est ensuite utilisé de façon que la synchronisation des stations de base (115-116) soit transparente pour les stations de base (115-116). L'utilisation du signal GPS (106-108) pour caractériser le signal de remplacement (110-113) permet également à ce dernier d'assurer le même degré de précision que le signal GPS (106-108).

Title: A fitting collar for sealingly joining an underroof to a skylight or another roof installation and a method for manufacture thereof
Inventor: JACOBSEN PER
IPC: E04D13/147
Filed: 1993-09-09
Abstract: For sealingly joining an underroof to a skylight or another roof installation a fitting collar is provided comprising a film element (7, 8) with a substantially U-shaped plane configuration with a cutout, at the sides of which there are flange parts (9, 10) for attachment of the fitting collar to mutually adjoined exterior sides (1-4) of the main frame structure of the window or the roof installation, in such manner that the film element is brought to extend substantially in parallel with the roof surface, in order to connect with adjacent parts (5, 6) of the underroof. The fitting collar can be manufactured in a simple manner, in that there in two overlapping lengths of film is produced transversal welds, at distances corresponding to a prescribed main frame width, whereby an obliquely extending part of each weld is formed with two parallel welded seams, while there in the edge zones at the opposite side edges of the lengths of film in extension of one and the other, respectively, of the two parallel welded seams are produced welded seams, which are perpendicular to the side edges. The collar elements are then separated by cutting along the cutting lines (22) between the parallel welded seams and parallel to the welded seams perpendicular to the side edges, and the collar is completed by cutting one length of film along the mid line between the welded seams with a subsequent bending upwards of the attachment flange parts.

The control assembly comprises a rotating means in the form of an upper and lower plates which rotate together relative to the boom of a cutting machine thereby causing the blade assembly to rotate into a forward facing position into the material to be cut. The control assembly further comprises an adjusting means in the form of a plurality of coil springs positioned between the upper and lower plates of the rotating means which serves to adjust the vertical movement of the blade assembly relative to the ground. A center mounting member mounts the bottom of the control assembly to the center of the top of the blade assembly for efficient control of the movements of the blade assembly. A combination angling and attaching means swivels the control assembly to thereby adjust the angle of the blade assembly relative to the ground and attaches the control assembly to the brush cutting machine. A quick attaching means in the form of a plate in rotatable engagement with a mating securing receiver integral with the lower surface of the bottom of the rotating means attaches the control assembly to the blade assembly. A method for controlling the movement of a blade assembly of a brush cutting machine is also disclosed.

Title: Incandescent lamp having a lifetime extended by two rectifying diodes and a resistor

Patent CA-2156654-A1 (CA)
Inventor: CHOUDHURY ABHIJIT KUMAR
IPC: H04L12/56
Filed: 1995-08-22
Abstract: A dynamic threshold system and method is disclosed for allocating memory among different output queues in a shared-memory ATM switch. The maximum permissible length for any individual queue at any instant of time is a function of the unused buffering in the switch. The dynamic threshold system and method deliberately reserves a small amount of buffer space, not allocating it to any currently active output queue, but attempts to equally share the remaining buffer space among the currently active output queues. The dynamic threshold system and method improve fairness and switch efficiency by guaranteeing access to the buffer space for all output queues, and by preventing any single output queue from monopolizing the memory at the expense of the others. The dynamic threshold system and method adapt to uncertain or changing load conditions. The packet losses that occur with dynamic thresholds tend to be clustered at a few offending queues, which is desirable in ATM systems, since it results in fewer messages being disturbed at higher protocol layers and, hence, fewer message retransmissions.      The dynamic threshold system and method are also extendable to handle traffic with multiple space priorities.

IPC: F02B1/04
Filed: 1995-11-06
Abstract: Disclosed is a power piston connected with a rod which connects to a pump piston at the opposite end of the rod. Conveniently, the rod can be rigidly or fixedly connected to both the power piston and the pump piston. Power from the power piston is delivered through the rod without rotation of the rod. The rod reciprocates to and fro in response to power from the piston which incorporates a cylinder surrounding the piston and suitable intake and outlet valves for operation of an internal combustion engine. Moreover, multiple units can be coupled to provide more volume or pressure or both.  By eliminating wrist pins and bearing assemblies, the power transfer is simplified.  While the foregoing describes only linear motion reciprocating the piston rod, the power end incorporates valves in a cylinder head to provide a two stroke engine or four stroke engine.
