Title: A filter co-processor
Inventor: TARRAB MOSHE
IPC: H04L27/06
Filed: 1997-07-08
Granted: 2000-09-26
Abstract: A filter co-processor (103, 109 and 109 fig.) within a Digital Signal Processor (DSP) takes advantage of the orthogonal nature of modulated signals during the equalization process. Since, after reception, only certain real/imaginary values of the received signals (112) are useful for demodulation, the filter co-processor only processes those values to estimate the transmitted signal. By processing only those values for demodulation, the filter co-processor is able to process information in a given amount of time, leading to increased processing when compared to the prior art.

Both the rollers at the encapsulation station, and the support roller at or adjacent the transfer station are positively driven and a control system ensures that the peripheral speed of the support roller in the transfer station is the same as the speed of the ribbon into and through the encapsulation station. The drive motor for the respective support roller at the transfer station is preferably a stepping motor which is adjustable to advance or retard relative to the ribbon speed at the encapsulation station. Sensors are also included to positively monitor the alignment of ribbon within the encapsulation process. Provision is also made monitoring the lateral positioning of images on the ribbon and for shifting the ribbon to accommodate any lateral misalignment.

Title: Coding and decoding of audio signals by using intensity stereo and prediction
Inventor: DIETZ MARTIN
IPC: H04S3/00
Filed: 1997-06-03
Granted: 2000-10-17
Abstract: In the coding and decoding of stereo audio spectral values both the intensity stereo process and prediction are used in order to achieve high data compression. If intensity stereo coding is active in one section of scale factor bands, the prediction for the right channel in that range is deactivated, whereby the results of the prediction are not used to form the coded stereo audio spectral values. To allow further adaptation of the prediction for the right channel, the predictor of the right channel is fed with stereo audio spectral values for the channel, which again are intensity stereo decoded.

Title: Electronic anti-theft element
Inventor: ALTWASSER RICHARD
IPC: G08B13/24
Filed: 1997-07-29
Granted: 2002-04-16
Abstract: An electronic anti-theft element consists of at least one spiral printed circuit (2; 3), a capacitor and a dielectric layer (4) arranged therebetween, or of two spiral printed circuits (2, 3) which are arranged on both sides of a dielectric layer (4) in an at least partially overlapping manner (forming resonant circuit (6)). The object of the invention is to provide a resonant circuit (6) which is less liable to be reactivated. For that purpose, in at least one selected area (8) (a rated break point) of the dielectric layer a short-circuit is created between the opposite capacitor plates or spiral printed circuits (2, 3) when a sufficiently high energy is supplied by a magnetic alternating field. The selected area (8) is locally reinforced, preventing the suppression of the short-circuit by mechanical stress and the reactivation of the anti-theft element (6).

Granted: 2002-12-10
Abstract: The invention relates to an assembly with a lower steering arm having a strut 1 and an attaching end 16. To achieve a cost-effective design while at the same time reducing the play between the attaching end 16 and the end of the strut 1 received therein, the attaching end 16 consists of a base member 18 and a cover 19. In the base member 18, there is supported the blocking pawl 34. The cover 19 is welded to the base member 18 and comprises a stop face 30 for the end face 10 of the strut 1, so that any tolerances in the region of the base member 18 provided in the form of a forging do not affect the position of the stop face 30. The latter can be aligned when connecting the base member 18 and the cover 19.      Because of its setting contour, the actuating lever 43 can be used for both the right-hand and the left-hand lower steering arm.

Abstract: The present invention relates to a process for the treatment of arsenic-containing sludge obtained by adjusting arsenic-containing waste water to a PH of 12 or greater by the addition of a calcium compound and subjecting the waste water to solid-liquid separation, the process comprising the steps of adding a calcium compound to the arsenic-containing sludge slurry obtained by the solid-liquid separation, dewatering the resulting sludge, drying the dewatered sludge, and calcining the dried sludge. According to the present invention, arsenic-containing sludge obtained by treating waste water to precipitate arsenic present therein can be calcined to yield a calcined product which involves no risk of arsenic redissolution when it is dumped. Moreover, there is no possibility that arsenic compounds may be volatilized during calcination.

Title: Anchoring system for a medical article
Inventor: BIERMAN STEVEN F
IPC: A61M25/02
Filed: 1998-10-16
Granted: 2010-02-09
Abstract: An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient's skin and supports a retainer. The retainer releasably receives a portion of the catheter and includes one or more retention mechanisms. The retention mechanisms inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. In one mode, the retention mechanism is positioned within a channel of the retainer and includes at least first and second members that project from opposite sides of the channel.  The members are arranged to cooperate with one another when the cover is closed so as to capture a structural portion of the catheter between the first and second members without substantially occluding an inner lumen of the catheter.

Title: Variable output rotary power generator
Inventor: BARTEL ROGER P
IPC: H02K21/00
Filed: 1999-01-16
Granted: 2003-10-28
Abstract: The present invention is directed to a downhole apparatus for quickly generating and regulating variable output electric power by varying the alignment of a pair of axially adjacent permanent magnets (84, 82) rotating within an armature (88) having electrically conductive windings. Each of the permanent magnets (84, 82) comprises a plurality of permanent magnetic segments having circumferentially alternating magnetizations. One of the permanent magnets (82) is fixed to the drive shaft (86) and the other permanent magnet (84) is movably mounted on the drive shaft (82) to enable the alignment or misalignment, as desired, of the magnetizations of the respective magnetic segments on the pair of permanent magnets (84, 82). When the magnetizations are completely aligned, the maximum electrical power is generated in the windings of the main armature (88); conversely, when the magnetizations are completely misaligned, zero electrical power is generated. Thus, the output power is regulated by varying the alignment of the pair of permanent magnets (84, 82), which is accomplished with a drag torque generator which creates a drag torque that is transmitted to the movable permanent magnet (84) by a torque converter.
