Patent CA-2276671-A1 (CA)
Inventor: COX JON T
IPC: A46B5/02
Filed: 1999-06-23
Abstract: A brush handle that provides an ergonomic grip to improve the manipulation and reduce the fatigue of the use of the brush. The brush handle provides a series of fitted control surfaces that allow a user to grip the brush handle in a comfortable and precise manner. These control surfaces are integrally formed on the brush handle on opposing surfaces for use by both right-handed and left-handed users. In one preferred embodiment, the brush handle is used for paint brushes. The brush handle also includes a protective mechanism to prevent paint from dripping or flowing onto the brush handle during use. The brush also provides a dip line to indicate the appropriate level of dipping the brush into a paint source.

Abstract: L'invention concerne une aube de turbine à gaz pour cycle combiné, cette aube étant capable d'être efficacement refroidie par une quantité appropriée de vapeur, des passages (a) étant ménagés pour permettre l'écoulement de cette vapeur de refroidissement, laquelle est alimentée de manière à pouvoir refroidir ladite aube de turbine à gaz depuis le coté intérieur de cette dernière, de sorte qu'un rapport (t/c) de l'épaisseur (t) de cette aube de turbine à gaz à la longueur tangentielle (c) est inférieur ou égal à 0,15. La vitesse à laquelle s'écoule la vapeur de refroidissement augmente au fur et à mesure que le rapport susmentionné (t/c) diminue, en supposant que le débit de cette vapeur de refroidissement qui s'écoule à l'intérieur desdits passages (a) reste constant, le coefficient de transfert thermique de la surface intérieure de ladite aube de turbine augmentant également de la même manière. En somme, lorsque le rapport (t/c) est inférieur ou égal à 0,15, ce qui correspond au coefficient de transfert thermique minimum ( alpha 1) pour permettre le refroidissement de l'aube de turbine, cette aube de turbine est efficacement refroidie, le faible débit de la vapeur, adapté à un cycle combiné, pouvant ainsi être entretenu. Par ailleurs, le rapport (t/c) varie de préférence entre 0,10 et 0,15, la vapeur récupérée pouvant par ailleurs être efficacement réutilisée.

Abstract: An isochronous data pipe provides a bi-directional path for data between an application and a bus structure. The isochronous data pipe includes the ability to send, receive and perform manipulations on any isochronous stream of data, including data on any number of isochronous channels. The isochronous data pipe is a programmable sequencer that operates on the stream of isochronous data as it passes through the isochronous data pipe. The isochronous data pipe is programmed by an application to perform specific operations on the stream of data before the data is either transmitted across the bus structure or sent to the application, thereby pre-processing and manipulating the data before it is delivered to its destination. The operations are performed on both the packet header and the data field of the data packet. The isochronous data pipe can be stopped and started on the occurence of specific events. In an alternate embodiment of the present invention, the isochronous data pipe is programmed to send and receive both isochronous and asynchronous data, including generating requests and appropriate packet headers.

Title: Non-terrestrial cellular mobile telecommunication station
Inventor: GEORGE ROBERT L
IPC: H04W84/06
Filed: 1998-10-05
Abstract: The non-terrestrial cellular mobile telecommunication station uses a number of non-interference techniques to extend the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to the non-terrestrial realm. For example, the polarization of the signals produced by the antenna elements of the non-terrestrial cellular mobile telecommunication station is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas to thereby minimize the possibiliy of interference with the ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. The transmit power of the non-terrestrial cellular mobile telecommunication station is also tightly controlled and of a magnitude to be rejected by the ground-based mobile subscriber stations and cell site transmitter-receiver pairs.

Patent CA-2311100-A1 (CA)
Inventor: CASIER HERMAN JORIS
IPC: H04L25/02
Filed: 2000-06-09
Abstract: An interface arrangement including the cascade connection of a differential pre-amplifier (HPA1, HPA2) and a comparator (DA), and generally known as fast Low Voltage Differential Signal [LVDS] circuit for interfacing electronic chips. The current standards for such a LVDS circuit specify a minimum switching threshold voltage for the small differential input signal, while the common mode input signal varies over a very large range, both at a very high frequency. This is achieved owing to the fact that the differential pre-amplifier comprises a first (HPA1) and a second (HPA2) half pre-amplifier, each receiving the arrangement inputs (INN, INP) in an opposite way. Each half pre-amplifier (HPA1 /HPA2) having first input inverter means (NN1, PN1) coupling an input (INN/INP) to an output (OUT1 /OUT2) thereof, and second input inverter means (NP1, PM1, PM2; PP1, NM1, NM2) coupling the other input (INP/INN) to the output via current mirror means (PM1, PM2; NM1, NM2). The output current of the second input inverter means is thereby inverted with respect to the output current of the first input inverter means. To obtain a controlled gain, the half pre-amplifier further includes a short-circuited inverter.
