Title: Dynamic bias for rf power amplifiers
Inventor: KAZAKEVICH LEONID
IPC: H03G3/30
Filed: 2001-03-28
Abstract: A communication signal input (20) provides a voice or data wireless signal (32) for transmission. A detector (14) removes the modulation component from the spread communication signal and provides a voltage to a voltage-to-current converter (16) controlled by a transmit power control (TPC) signal (26). An output current (30) and the output signal (38) are connected to a current mirror (18) that outputs a bias signal (34) to a radio frequency (RF) power amplifier (12). An independent claim is also included for a method of dynamically biasing an RF power amplifier.

Title: Diagnosis and treatment of tumor-suppressor associated disorders
Inventor: REEVES ROGER HARPER
IPC: C12Q1/6827
Filed: 2001-08-15
Abstract: Methods are provided for detecting a cell proliferative disorder associated with TSLC1 by contacting a proliferating cell of a subject suspected of having the disorder with a reagent that detects TSLC1 and detecting the level of TSLC1 in the proliferating cell. TSLC1 is a single gene whose expression is reduced or absent in A549 and some other NSCLC, hepatocellular carcinoma and pancreatic cancer cell lines. It has further been discovered that TSLC1 expression or suppression is perfectly correlated with promoter methylation state. Restoration of TSLC1 expression to normal or higher levels is sufficient by itself to suppress tumor formation. The invention further provides methods of treating such disorders by contacting cells of a patient suffering from the disorder with a therapeutically effective amount of a reagent that modulates TSLC1 level in the proliferating cells.

Patent AU-2001288990-A1 (AU)
Title: Method and device for signaling data transfer between a usb port and a usb smart card module
Inventor: LEYDIER ROBERT ANTOINE
IPC: G06K17/00
Filed: 2001-09-10
Abstract: A method and device are disclosed for detecting successful transfers between a Universal Serial Bus (USB) port and a USB smart card and generating a signal that provides an indication of the USB transaction activity. This USB transaction activity signal is modulated according to the USB transaction activity and drives a Light Emitting Diode (LED) in a preferred embodiment of the invention. A counter internal to the USB smart card scales the transaction activity signal such that it is perceptible to the user. Because the current through the LED depends upon the USB transaction activity, the brightness of the LED varies according to the USB transaction activity. The LED may be driven from a current mirror sink or source, or a current switch sink or source.

Filed: 1999-08-05
Abstract: L'invention concerne un élément de régulation (10) d'une valve (12) qui présente une entrée (16), une sortie (18) et un trajet d'écoulement primaire entre les deux. L'élément de régulation (10) peut pivoter pour modifier la zone de régulation (24) du débit du trajet d'écoulement primaire.

Title: Method for the production of high dispersion settled silicon oxides
Inventor: SIMEONOV DANAIL B
IPC: C01B33/18
Filed: 1989-11-23
Abstract: This method finds application in the perfume and cosmetics and rubber industries. It shortens the process time while enabling the control of growth and compaction of particles. The method comprises neutralizing an alkaline silicate with an acidic reagent, carbon dioxide, at pre-selected two-stage volumetric concentration of the gas-air mixture and growth factor enabling the forming of a product with specific physical and chemical characteristics. Specifically, the method comprises adding 40-90 percent (v/v) concentrated CO2 to a water glass solution at pH of the environment 10.5-11, followed by bringing down the CO2 concentration to 10-50 percent (v/v) and pH to 8.5-9, respectively. The temperature is maintained at 75-85 degrees C. An extra water glass solution can be added at the rate of 2-50 g/hour SiO2 in the second stage for the purpose of controlling the quality of SiO2. The method results in obtaining SiO2 with BET specific area of 250 m<2>/g, oil absorption capacity 260, bulk density 75 g/l and particle size values ranging between 1 and 4 mkm.
Patent WO-0048012-A1 (WO)
Inventor: FELD MICHAEL
IPC: H05K13/08
Filed: 2000-02-11
Abstract: The invention relates to a method for the verification of the presence and proper orientation of a component on a printed circuit board (1). The board has a plurality of areas (10) for receiving a component (20) respectively. Each area is marked in the center thereof with a first marker (30). Adjacent each area, and indicative of the polarity of the component, a second marker (40) is marked on the board. The presence or absence of a component can be evaluated by inspecting the board after it has been populated and determining whether any of the first markers appear, indicat     ing that a component is missing. Verification of the polarity of a component is done by placing a marker (40) on a portion of a component required to be installed in a predetermined position indicative of polarity. Inspection of the board once it has been populated will determine if the component is in the proper orientation by verifying if the second marker and the marker on the component are in alignment. Preferably, the first marker and the second marker are of different colours, and are preferably UV compatible layers. Additionally, the method of the invention, when applied between the leads of a multi-legged component or between discrete components, such as by the etching of additional portions of the solder mask or by adding an additional layer, will produce a shadow on the reflective surface, thereby identifying a short at that location.

Title: Procedes et appareil d'emboitement d'elements tubulaires
Inventor: SKREPNEK ANDY
IPC: B60N2/68
Filed: 2003-03-17
Abstract: L'invention concerne un procédé et un appareil d'emboîtement d'au moins un premier tube (10) doté d'un premier espace diamétral entre des points opposés de la paroi du tube qui est plus large que le premier espace diamétral. Le premier tube est chargé sur un madrin (50) doté d'une extrémité de perforation (54), et est placé dans un bloc de support (30) pourvu d'une cavité de support (32) sensiblement conforme à la surface externe du premier tube. Le second tube est placé sur un bloc de réception (40) qui est pourvu d'une cavité de réception sensiblement conforme à la surface externe du premier tube. L'extrémité de perforation du mandrin est actionnée à travers le second tube jusque dans la cavité du bloc de réception, suivi du premier tube. Lorsque le premier tube atteint une limite inférieure de la cavité de réception, le premier tube est comprimé dans le sens axial. Le madrin soutient l'intérieur du premier tube, la cavité de support empêche la partie arrière du premier tube de faire saillie vers l'extérieur, et la cavité de réception empêche la partie avant du premier tube de faire saillie vers l'extérieur. Par conséquent, la partie du premier tube placée à l'intérieur du second élément tubulaire fait saillie sous l'effet d'une force de compression axiale, emboîtant ainsi constamment le premier tube dans le second tube. Les étapes de perforation peuvent être séparées des autres étapes selon le procédé de l'invention, ou le second tube peut être préalablement perforé. Dans d'autres modes de réalisation, le procédé et l'appareil de l'invention peuvent créer un emboîtement replié et/ou un ensemble emboîté en forme de T.

Patent CA-2007973-A1 (CA)
Inventor: RAITH ALEX K
IPC: H04L27/14
Filed: 1990-01-17
Abstract: A method and an arrangement are described for controlling the frequency of a radio receiver which receives signal sequences subject to interference and which include a synchronizing sequence and a data sequence.  A signal sequence is A/D converted to signal points (I,Q) intended for analysis, and a Viterbi algorithm is adapted to the prevailing interference with the aid of the synchronizing sequence.  The data sequence is Viterbi analyzed through a large number of calculating stages, for the purpose of determining the bit sequence of the data sequence.  According to the invention, a bit sequence is extracted during the Viterbi analysis, with a time delay (TE), subsequent to effecting a few calculating stages, and a corresponding extracted signal point is calculated.  The analysis intended signal point corresponding to the extracted signal point is divided and time delayed, and phase compared  with the extracted signal point. Corresponding phase comparisons are made with respect to consecutive signal points in the data sequence and the angular magnitudes obtained in the phase comparison are low-pass filtered and integrated to form an angle shift signal. The analysis intended signal points are displaced angularly by the angle shift signal prior to the Viterbi analysis.
