Patent CA-2347268-A1 (CA)
Title: Transmission system using multicarrier modulation
Inventor: ASLANIS JAMES T
IPC: H04L27/26
Filed: 1995-07-11
Abstract: A discrete multitone modulation transmission system is described in which frame synchronization is monitored at the receiver by correlating frequency domain complex amplitudes of a synchronizing frame with a stored synchronizing pattern. If the correlation result falls below a threshold, indicating a loss of frame synchronization, a plurality of correlations are performed, in each case using the stored complex amplitudes of the synchronizing frame multiplied by a respective complex value representing a respective complex demtation corresponding to a respective possible time shift of the synchronizing frames. The best correlation result, if it exceeds another threshold, indicates a time shift for restoring frame synchronization, this being possible before the next synchronizing frame is received.

Title: Continuously variable power split transmission (cvpst) system for use in a hybrid vehicle
Inventor: KMICIKIEWICZ MAREK
IPC: B60W10/101
Filed: 2001-05-25
Abstract: The present invention is concerned with a continuously variable power split transmission(CVPST) system for use in a hybrid vehicle. The vehicle has a first motor, such as an internal combustion (IC) engine and a second motor, such as an electric motor. The system has a step-up gearbox for providing additional fixed speed ratios to extend overall transmission conversion range (CR) of the system. The system also has a speed variator and a countershaft being operatively connected to the second motor of the vehicle so that any power input applied by the second motor to the countershaft reduces the power flowing through the speed variator. Also, an adjustment of the variator speed ratio i v allows a passage from underdrive i UD to overdrive i OD range of speed ratios in the step-up gearbox to be synchronized.

Patent CA-2354393-A1 (CA)
Inventor: REGEL PETR ANATOLIEVICH
IPC: F02B53/00
Filed: 1999-12-10
Abstract: Cette invention se rapporte aux moteurs à combustion interne, et concerne un moteur axial rotatif comprenant un corps (1) dans lequel se trouve un canal annulaire ondulé (10) pour le corps de travail, et dans lequel est monté un rotor (5) dont la partie périphérique se trouve dans ledit canal (10). La partie périphérique du rotor (5) comporte des fentes dans lesquelles sont montées des pales mobiles (8) qui, lors de la rotation du rotor (5), se déplacent le long du canal ondulé (10). Les pales (8) sont en forme de cylindres aplatis comportant des gorges tangentielles (16) diamétralement opposées, et possèdent des parties d'extrémité en forme de disque qui sont disposées des deux côtés des gorges (16). Les gorges situées autour des parties en forme de disque comportent des éléments d'étanchéité (17) qui sont montés de manière à pouvoir se déplacer sur le périmètre desdites parties en forme de disque. Les fentes du rotor (5) ont une forme correspondant à la section des pales (8) dans un plan diamétral qui est perpendiculaire à l'orientation des gorges tangentielles (16). Grâce à la forme ronde des parties en forme de disque des pales (8), les éléments d'étanchéité (17) peuvent tourner dans les gorges des parties en forme de disque lorsque lesdites pales (8) exercent une pression le long du canal (10), ce qui entraîne une usure uniforme desdits éléments ainsi qu'une plus grande fiabilité de fonctionnement du moteur.

Title: Adjustable wing plow with fixed pivot
Inventor: QUENZI PHILIP J
IPC: E01H5/06
Filed: 2001-10-02
Abstract: A plow assembly for vehicles, such as pickup trucks and tractors, or bulldozers or graders, for moving snow or other plowable materials has at least one extendable, forwardly pivotable plow wing which is pivotable at a hinge at one end of a main plow for movement between an aligned position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. The plow wing includes an inner and outer portion, whereby the outer portion is slidably mounted to the inner portion for sliding movement along the inner portion between a retracted and an extended position. One or more actuators, such as fluid power cylinders or the like, are connected to the plow wing to move the wing between the retracted, extended, aligned and forwardly angled positions. In one preferred embodiment, an extendable plow wing is pivotally mounted on each end of the main plow with a pair of fluid cylinders connected to each of the respective plow wings. The fluid cylinders in each respective pair are operable independently of one another to move the plow wings independently between their respective retracted, extended, aligned and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U-shape which facilitates pushing snow or other material without the material slipping off the plow blade ends. The wings are extendable and retractable when the plow is in the U-shape in order to adjust the carrying capacity of the plow.

Title: Communication control apparatus and method
Inventor: FUJIMORI JUNICHI
IPC: H01S5/227
Filed: 2001-10-31
Abstract: One or more nodes on a communication network are selected and set as one node group. In each of the nodes, group identification information representing the node group to which the node belongs is stored in advance. The group identification information is attached to the header of a data packet to be transmitted, so that nodes constituting a node group that should commonly receive data can be readily identified by comparing the group identification information imparted to the transmitted data packet and the group identification information stored in each receiving node. Given node can choose to become a node of a particular function, such as a clock master node, in which case control is performed to delete, from the node group, a node having so far played the role of the node of the particular function in such a manner that there exists only one node of the particular function per node group.
