Title: Power transmission for snowmobile
Inventor: IZUMI YOSHIO
IPC: B60K17/06
Filed: 1998-01-29
Granted: 2004-07-27
Abstract: A power transmission system for a snowmobile reduces the weight thereof, and allows a streamlined body to be obtained. A drive side pulley of a V-belt transmission is mounted on a right end of a crankshaft of an engine. A gear box is disposed on the right side of a driven side pulley of the V-belt transmission at a position near the driven side pulley. The driven side pulley is fastened to an input shaft. Thus, the V-belt transmission and gear box are disposed on the same right side of the engine, so that the connecting shaft for connecting the V-belt transmission to the gear box is shortened and the weight thereof is reduced.      Further, the V-belt transmission and the engine are disposed between a pair of right and left main frames, and the gear box is disposed outside of the right main frame, to thereby shorten a distance between the right and left main frames.

Granted: 2001-05-29
Abstract: An adaptive array apparatus which can follow high speed movement of an interference signal source while reducing breathing noise and maintaining high quality of an output signal. The adaptive array apparatus uses an indicative value relating to the amplitude of an output signal of a beam former and having higher sensitivity with respect to the target signal source than sensitivity with respect to another signal source, and an indicative value relating to the amplitude of an output signal of a beam former having lower sensitivity with respect to the target signal source than sensitivity with respect to another signal source, and determines a step size of an adaptive algorithm in the adaptive filter. Thus, when a constant determining a step size is set large, following speed with respect to the movement of the interference signal source accordingly becomes higher to reduce signal degradation and breathing noise.

Title: Material for enhancing water tolerance of composite boards
Inventor: SLEETER RONALD T
IPC: C09J191/00
Filed: 1998-08-27
Granted: 2005-08-23
Abstract: A method of enhancing water resistance of composites uses a water repellant material which may be applied toward and other fibrous vegetable materials. The method begins with a saturated vegetable or animal fat triglyceride having a low iodine value. The triglyceride is rendered in a form which may be a fine powder, an emulsion, or a dispersion in a liquid. The sprayable triglyceride and a bonding agent are applied to the fibrous materials, preparatory to a press binding. There, the sprayed material is subjected to a hot press cycle in order to form a bonded fibrous composition. The low Iodine Value triglyceride may be selected from a group including hydrogenated vegetable oil, palm oil, stearine, winterized low IV fractions, soy stearine, animal fat, hydrogenated animal fat, and fractionated fats or blends of these materials.

Patent CA-2251504-C (CA)
Inventor: TAKAGI TADASHI
IPC: H03F1/32
Filed: 1998-10-26
Granted: 2001-09-04
Abstract: A feedforward amplifier which includes a distortion detector, a distortion eliminator, an error power extractor, a first level detector and a first controller.          The error power extractor extracts output error power due to variations in the distortion eliminator by combining the output signal from the distortion eliminator with the signal from a first linear signal path in the distortion detector in opposite phases.  The first level detector detects the output error power extracted by the error power extractor, and the first controller controls a first variable attenuator and a first phase shifter which are interposed in the distortion eliminator such that the output error power is maintained at zero.  This can solve a problem of a conventional feedforward amplifier in that the power level of the pilot signal must be increased to heighten the detection sensitivity of the pilot signal because the detection level of the pilot signal becomes minimum at an optimum operation point, and that the increasing power of the pilot signal degrades the communication quality of a system employing the conventional feedforward amplifier.

Abstract: A system and method for balancing loads in a computer system is disclosed. The system and method assess the health of various paths in a computer system by determining the health or status of at least two layers on each path. A health or status of the paths is then determined based on the information of tine health of each layer in the path. A load balancing device routes information for processing to the various paths based on the determined health of the paths. To better estimate the health of a path, algorithms which weight the health signals for each layer are used giving greater weight to layers of greater importance. The system and method can also add or remove additional paths if the combined health of the existing paths is determined to be above or below a predetermined value. In addition, the weight of certain layers can be locked in to provide for updating of specific layers. A topology of the computer system is used to determine the health or status of the paths and this topology can either be entered by a programmer or independently determined by the load balancing system.

Title: Frequency selective predistortion in a linear transmitter
Inventor: LYENDECKER ROBERT R
IPC: H03F1/32
Filed: 1998-05-05
Granted: 2003-11-11
Abstract: A system for linearly transmitting an amplified output signal using predistortion is disclosed. The system uses a straight inverse modeling sche me to more easily and accurately determine the inverse of the distortion caused by a power amplifier (1002) of a RF transmitter. The direct inverse modeling scheme of the present invention indexes the LUT (1020) using the modulated input signals instead of the potentially noisier output signals, which helps to increase the accuracy of the predistortion. The predistorter system (1010 ) stores complex coefficients in the LUT (1020), which are then used as the ta p weights of a digital filter implementing the predistorter (1022). Finally, t he trainer (1008) uses a modified version of the power amplifier (1002) output signal. The modified power amplifier (1002) output signal has the in-band distortion removed from the power amplifier (1002) output signal.

Abstract: A method and means for self-policing and automatically rate-limiting multiple-user online forums. The preferred embodiment of the invention includes a set of rules that permit users to censure other users. A censured user has one or more "privileges" (which may include access to the online computer system or the effective message rate of a communications connection) taken away or diminished; the privilege is gradually restored if the censure user behaves.  The censuring participant and other pertinent participants are notified of the effect of the censuring on the censured user. In another aspect of the invention, the online computer system automatically tracks the rate at which a user sends certain types of messages, and can message rate limit a user who uses too many system resources by sending a large number of messages in rapid succession.
