Patent CA-2286086-A1 (CA)
Inventor: RUBIN PHILIP A
IPC: G01S5/14
Filed: 1998-04-15
Abstract: An integrated receiver decoder (IRD) (37), commonly called a set-top box (37), has a global positioning system (GPS) receiver (44). The GPS receiver (44) checks to see if the IRD is as an authorized location and allows descrambling (46) of video signals only if the location is authorized. A central access control system (48), remote from the customers/viewers, has a high quality GPS receiver and sends some GPS data in the transmission medium used to send video signals to the customers. The set-top box (37), referred to as a customer access control, establishes different geographic restrictions on different of various video signals. Location-specific signals require that the set-top box be at a single fixed location for descrambling. Region-specific signals are accessible only if the set-top box (37) is in a geographic region authorized for reception, there being several such regions.

IPC: H04W72/14
Filed: 1999-08-26
Abstract: A method for controlling channel access in a mobile communication system. A base station generates a broadcast channel frame, which includes status information indicating whether channel codes which are changing in real time are occupied or not. The base station transmits the broadcast channel frame at predetermined intervals. Then, a mobile station selects an available channel code based on information from the received broadcast channel frame, generates a channel assignment request message, and transmits the channel assignment request message on a random access channel. Upon reception of the channel assignment request message on the random access channel, the base station assigns a channel, sets a transmission rate, and transmits the information on a forward access channel.

Patent CA-2317745-A1 (CA)
Title: High speed grinding wheel
Inventor: WU MIANXUE
IPC: B24D3/14
Filed: 1998-09-25
Abstract: A method of obtaining superabrasive grinding performance from tools employing less expensive, non-superabrasive conventional abrasive grain involves operating the conventional abrasive tool at ultra high tangential contact speed, (that is at least about 125 m/s). Such ultra high operating speeds can be achieved with segmental abrasive grinding wheels having segments formed from vitreous or resin bonded particles of aluminum oxide, silicon oxide, iron oxide, molybdenum oxide, vanadium oxide, tungsten carbide, silicon carbide and the like. The abrasive segments can be cemented to the con of the tool with an adhesive such as epoxy cement. Abrasive segments can be made to a significantly greater depth than traditional superabrasive-bearing segments, and consequently, should provide long life as well as high performance.    Additionally, conventional abrasive segments are easier to true and dress and to make into intricate profiles for grinding complex shaped work pieces.
Patent CA-2320179-A1 (CA)
Title: Method of regulating the rotational speed of multicylinder internal combustion engines
Inventor: FLACH MICHAEL
IPC: F02D41/16
Filed: 1999-02-08
Abstract: The invention relates to a method for regulating the engine speed in multi-cylinder internal combustion engines in order to achieve, in a simple and cost effective way, a precise and rapid detection of the engine speed enabling a stable regulation of the motor at a constant speed when the speed changes periodically and temporarily. For this purpose, the time required for a fixed sequence of successively sampled pulses is measured continuously and used to form actual equidistant and non-corrected engine speed values (n). The number of successively sampled pulses is fixed on the basis of the number of the engine cylinders and the number of pulses that can be produced by the polar wheel each time it turns. In addition, the time required for a number of sampled pulses corresponding to a complete rotation of the polar wheel to be stored, is measured and used for producing a mean engine speed (N). The difference between the mean engine speed (N) and each actual uncorrected engine speed value (n) is smoothed for producing actual corrected engine speed values (x), said difference value is bound and then added to the actual non corrected engine speed (n). The actual corrected engine speed values (x) are compared to the predetermined value of the set speed engine (w) and transferred to a regulator (3) producing an output value (y) used for controlling the regulating means.

Title: Startup procedure for international line powered daa
Inventor: HOLLENBACH KEITH EUGENE
IPC: H02J7/00
Filed: 2000-10-04
Abstract: A line powered data access arrangement (DAA) is disclosed which adaptively allows proper operation with power supplied from a telephone line as conditions warrant, while at the same time satisfying the relevant requirements of many countries. In the line powered codec, a startup procedure for the international line powered codec uses register settings, e.g., country-specific register settings, which are powered and maintained from the low voltage side (e.g., from the PC or modem side) of the line powered codec. In this way, even during low line power conditions the programmed state of the line powered codec can be maintained, thus a default condition will not necessarily returned to by the line powered codec upon reset due to a power loss in the telephone line. In another aspect, a charge storage device such as a charge capacitor is charged from a charge pump formed from a differential clock signal from the low voltage side. A current and voltage detection module in the line powered codec is always powered from the telephone line. Upon detection of an off-hook signal or a power down condition, the current detection module determines if/when the current and voltage on the telephone line is sufficient to power certain circuits on the line powered codec. If sufficient power is not present, the line powered codec does not power up. However, the line powered codec will power up if sufficient current is detected. In another aspect, a plurality of power rails may be provided. A first power rail may be associated with the line power, a second power rail may be associated with a low voltage side power source, e.g., a charge storage device. A third (and other) power rails may be switchably connected to either the first power rail or second power rail as line power conditions and on-hook/off-hook conditions warrant.
