Title: Automatic semiconductor wafer sorter/prober with extended optical inspection
Inventor: CHAPMAN ROBERT L
IPC: G01R31/01
Filed: 1997-07-07
Abstract: A method and apparatus (11) for visually inspecting and sorting semiconductor wafers (23a, 23b, 23c) and the individual microcircuits or chips thereon. The preferred embodiment employs a scanner (37) to obtain a virtual reality image of the wafer (23) and all chips are identified and sorted by applying high-speed image processing routines. The resulting wafer map provides unique image controlled chip coordinates making the chips identifiable even after the chips are diced apart. The wafer may contain different kinds of chips in irregular patterns. A gross-defect, visual inspection (17) sorts out defective chips based on image completeness maximizing the yield and throuthput. All inspections and identification are performed on the virtual wafer (23) or chip images scanned into a computer memory with full physical wafer correlation but without having to manipulate the wafer. The inspection time is, therefore, largely free due to overlapping it by regular transport operations.

Title: Barre de pratique
Inventor: BERNARD GILLES
IPC: G09B15/00
Filed: 1999-02-15
Abstract: Une barre de pratique (24) pour claviériste, particulièrement utile pour les exercices exécutés au piano, sert d'appui pour les poignets et de référence et de guide dans les déplacements des mains le long d'un clavier (20), comprend une barre (26) ajustable en hauteur et à distance, disposée en relation et parallèlement avec le clavier (20). A la barre (26) s'attachent aux extrémités deux bras (28) parallèles entre eux et perpendiculaires à la barre. Un tube de fixation (32) en U pivote sous le clavier à l'aide d'une poignée (39) et possède deux extensions (30) qui s'engagent dans les bras parallèles (28) par un joint (50) permettant un mouvement rotatif universel pouvant positionner la barre (26) en fonction de la taille du claviériste et de l'exercice pratiqué et de même que pouvant la retourner à l'envers cachée sous la table. Le tube de fixation peut être soutenu par des attaches (34) ou par un pied. La poignée (39) peut être mue par une pédale.
Patent CA-2260761-A1 (CA)
Title: Vaccins comprenant des antigenes fixes sur leurs supports par des liaisons labiles
Inventor: BEEKMAN NICO JOHANNES CHRISTIA
IPC: C07K14/015
Filed: 1997-06-24
Abstract: L'invention se situe dans le domaine des vaccins et des préparations immunogènes. Normalement, dans ces préparations, les antigènes et les composés supports sont irréversiblement couplés par une liaison stable. L'invention, au contraire, concerne des vaccins et des préparations immunogènes dans lesquels l'antigène (qu'il soit une protéine, un peptide, un hydrate de carbone ou n'importe quelle autre molécule pouvant être utilisée comme antigène en vue d'une immunisation/vaccination) et le composé support sont couplés de manière réversible et labile, par ce qu'on appelle une liaison labile. Etonnamment, comme cela a été démontré dans la partie expérimentale de cette demande, un antigène faiblement immunogène par lui-même peut ainsi provoquer une meilleure réponse qu'avec les méthodes dans lesquelles l'antigène et le composé support sont liés par une liaison stable.

Patent CA-2261731-A1 (CA)
Inventor: BROPHY MARK E
IPC: F28D19/04
Filed: 1997-08-14
Abstract: A rotary regenerative air preheater has heat exchange baskets (22) which contain the mass of heat absorbent material commonly comprised of stacked plate-like elements (46).

Title: Gas pressure regulator having burn-out protection system
Inventor: DIEHL GREGORY WILLIAM
IPC: G05D16/06
Filed: 1999-03-05
Abstract: A gas pressure reducing regulator which includes a flexible diaphragm which is biased by a spring so as to control the opening of the valve of the regulator and thus the delivery pressure of the gas being regulated.      The regulator includes a system for effectively containing an accidental oxygen fire, or the like, within the body of the regulator, and protecting the internal components from ignition. The system includes a plunger which resides in an axial bore in the regulator body and shields the diaphragm from hot combustion products, and plunger-retaining features which prevent the plunger from being displaced from its axial bore. Also, the regulator has provision for venting the interior of the regulator to the atmosphere in the event of an excessive overpressure therein.

Abstract: The present invention relates to the encoding and decoding respectively of serial data, using block codes.      Encoding of a serial bit stream of input data in groups of N bits, so-called words (O), to serial output data in groups of 2N bits, so-called code words (KO), is preferably carried out by a logic circuit in a manner such that N of the 2N bits in the code words (KO) are comprised of the N bits input data, unchanged or inverted, and remaining bits in the code words (KO) are determined so that, seen statistically, the code words (KO) will include approximately as many zeros as ones, such that each code word (KO) will be unique for each word (O), and such that at least one of the code words (KO) will remain unique even in bit stream shifting processes. Decoding includes further encoding in a similar logic circuit and comparison of the incoming code words with the code words encoded in the logic circuit, in a predetermined manner.

Title: Electrolysis cell and internal combustion engine kit comprising the same
Inventor: ROSS BILL
IPC: F02B43/10
Filed: 1999-07-26
Abstract: An electrolysis cell and internal combustion engine kit including an electrolysis cell is disclosed. The cell includes a sealed plastic body having an inlet and an outlet. The plastic body includes a first terminal located at the top of the body, a second terminal located adjacent to the first terminal and insulated conductors associated with each terminal extending through the body and towards the bottom end thereof. Each terminal ends in a respective anode and cathode which are operatively connected to the terminals. The anode and cathode are spaced apart from one another within the body. When an electrolysis solution is placed in the body, and a current provided across the electrodes, water is caused to decompose into hydrogen and oxygen. These combustible gases are then passed into the internal combustion engine to increase the efficiency and power thereof. In one embodiment a reservoir is provided to ensure that the level is maintained in the cell. Safety features include a low level sensor switch and low level shut off, a temperature sensor and high temperature cut off, and a pressure sensor and high pressure cut off.

IPC: H04M1/715
Filed: 1998-03-18
Abstract: A method and apparatus for allowing two or more Wireless Local Loop telephone users to communicate simultaneously with each other and a far end user in which earseal and hybrid echo is reduced. The present invention operates within a Wireless Local Loop telephone having a plurality of telephone inputs, one of which is a dedicated handset (16) and at least one other input being a standard analog telephone (18, 20). Two echo cancellers (30, 32) are used within the phone to reduce the echo produced by the impedance mismatch of a 4-to-2 wire hybrid (44) and the dedicated handset (16). A first echo canceller (30) is optimized to remove the earseal echo generated at the dedicated handset (16) while a second echo canceller (32) is optimized to remove the hybrid echo generated at the 4-to-2 wire hybrid (44). The two echo cancellers operate independently such that neither echo canceller need adapt its filter coefficients when a change in the echo channel characteristics occurs, such as when a speaker hangs up or another speaker joins the conversation.
