Title: Apparatus and method for increasing the flexibility of and straightening flooring strips
Inventor: SMITH WILLIAM S
IPC: E04F15/02
Filed: 1998-08-04
Abstract: An apparatus for increasing the flexibility of and straightening wooden flooring strips of the type having a top surface having a decorative finish and a base surface opposed to the top surface. The base surface has a multiplicity of closely spaced-apart scores extending into the flooring strip from the base surface transverse to the length of the flooring strip along substantially the entire length of the flooring strip to relieve stress and increase flexibility in the wood strip for more closely adhering to irregularities of a sub-floor. The apparatus has an infeed zone for feeding flooring strips downstream from an upstream processing station and an outfeed zone for discharging the flooring strips to a downstream processing station. A conveyor conveys the flooring strips downstream from the infeed zone to the outfeed zone. Bending rollers are positioned between the infeed zone and the outfeed zone for applying a progressive bend to the flooring strips as they move downstream on the conveyor of a magnitude to break a quantity of wood fibers in the flooring strip sufficient to equalize tension between the top surface and base surface to thereby straighten the flooring strip along its length.

Patent CA-2251098-A1 (CA)
Inventor: HUANG ZHONG SHOU
IPC: H01L27/146
Filed: 1996-05-08
Abstract: A high resolution flat panel for radiation imaging (20) includes an array of pixels (22) arranged in rows and columns. Gate lines (24) interconnect the pixels (22) of the rows while source lines (26) interconnect the pixels of the columns. Gate driver circuits (28) provide gate pulses to the gate lines in succession in response to input from a control circuit (30) to select the pixels on a row-by-row basis. The source lines (26) lead to charge amplifiers (32) for sensing the signal charges stored by the pixels when the pixels are selected. At least one pair of adjacent pixels in each row of the array shares a source line. Gating of the pairs of pixels in the rows that share a source line is controlled by control logic to ensure that signal charges stored by only one of those pixels is applied to a shared source line at a time. This allows the number of charge amplifiers in the flat panel to be reduced while maintaining high resolution.

Title: Rotary engine
Inventor: HUCKERBY SCOTT
IPC: F02B53/12
Filed: 1998-12-21
Abstract: Disclosed is a three rotor engine of the intermeshing lobe and groove type wherein the rotors are transversely aligned and sealingly cooperate with a casing to provide a power rotor, an abutment rotor and a scavenging rotor. The scavenging rotor provides for a positive formation of an air which forces exhaust gases out a primary exhaust port and also aids in air intake through a primary air intake port by expanding the chamber defined between adjacent lobes which provides for the formation of a positive air charge in the chamber for use in the combustion engine. The scavenging rotor helps in reducing unburnt fuel emissions in the exhaust as it provides a charge of fresh air into the exhaust from the abutment or middle rotor to allow complete combustion of any fuel still remaining unburnt in such exhaust.

Title: Methods for increasing the efficiency of recombinant aav product
Inventor: SAMULSKI RICHARD J
IPC: C12N7/01
Filed: 1998-04-14
Abstract: The present invention relates to methods and compositions for increasing the production of high titre stocks of recombinant AAV  (rAAV) through regulation of expression of the AAV REP and CAP proteins. The methods and compositions of the invention are based on the observation that the low level expression of the AAV REP protein increases the production of AAV viral capsid protein and efficiency of packaging resulting in production of higher titre recombinant viral stocks.  The invention encompasses recombinant AAV vectors that direct the expression of AAV REP and CAP proteins (see the figure) and the use of such vectors for the production of novel stable cell lines capable of generating high titre rAAV vectors. The invention provides methods for regulating the expression of the AAV REP gene at the transcriptional and post-translational level.

Title: Procede et appareil de compression de donnees
Inventor: PETERS MICHAEL ALAN
IPC: G06T9/00
Filed: 1998-06-04
Abstract: L'invention concerne un procédé et un appareil de compression de données. L'invention décrit l'application de plusieurs schémas de compression aux données afin d'obtenir de meilleurs rapports de compression. Dans un premier mode de réalisation, chaque pixel est comprimé par un schéma de compression basé sur une entropie, sélectionné parmi plusieurs schémas de compression différents basés sur une analyse de coût de probabilité. Dans un deuxième mode de réalisation, chaque pixel est comprimé sur la base d'un contexte hybride formé au moyen de plusieurs schémas de compression pour une meilleure détermination de probabilité et donc un meilleur codage d'entropie. Dans les modes de réalisation selon l'invention, on applique un schéma de compression de contexte similaire à JBIG, ainsi qu'un schéma inverse. Le schéma de contexte forme un contexte statistique provenant d'une séquence à concaténation de valeurs de pixels antérieures. Le schéma inverse permet d'obtenir une méthode d'estimation de valeur de gris sur la base de valeurs de pixel antérieures et de valeurs de seuil respectives. On tient des statistiques sur la valeur courante réelle d'un pixel et sur la différence entre une valeur de gris estimée et la valeur de seuil de pixel courante.

Title: Method and system for controlling radio communications network and radio network controller
Inventor: RINNE MIKA
IPC: H04B7/005
Filed: 1998-04-17
Abstract: The invention relates to a method and system for controlling a radio communications network. The invention is advantageously applied in broadband radio networks (GRAN) offering fixed network services to their users. An idea of the invention is that in conjunction with a connection set-up a radio network controller is selected via which user information flows for the whole duration of the connection. That radio network controller is here called an anchor controller (aRNC). If a connection is handed over to a base station that belongs to another radio network controller (bRNC), the user information is directed so as to travel to the active radio network controller via the anchor controller. A second idea of the invention is that in preparation for a handover a list in a neighbouring radio network controller is compiled of those base stations that would constitute a candidate set should said neighbouring radio network controller be made the active radio network controller. The invention makes it possible, among other things, to reduce the load of the core network of a cellular network and to decrease transmission power in conjunction with a handover.

Title: Non-handed horizontal adjustor mechanism
Inventor: DENLEY RONALD S
IPC: G01B5/25
Filed: 2000-02-18
Abstract: A non-handed horizontal headlamp adjustor mechanism. The mechanism includes a directing member and drive structure operatively coupled to the directing member. The directing member is engageable with a reflector of a headlamp assembly mounted in a vehicle. The drive structure is rotatable to effect movement of the directing member and adjust a position of the reflector. Indicia is provided on the mechanism generally proximate the drive member. The indicia relates to which direction to rotate the drive structure to effect movement of the reflector in a direction which is either toward or away from a centerline of the vehicle. The indicia renders the headlamp adjustor mechanism usable with headlamp assemblies of the vehicle which are both right and left of the centerline of the vehicle, and the indicia is accurate with respect to rotation of the drive structure and resulting movement of the reflector regardless of whether the headlamp adjustor mechanism is engaged with a headlamp assembly which is to the right or left of the centerline of the vehicle. As a result, the horizontal headlamp adjustment mechanism provides cost savings in labor, parts, and logistics of producing equal quantities of each because the same mechanism can be installed on either side of the vehicle and still provide accurate indicia.
