Title: Transmission circuit with improved gain control loop
Inventor: ENOKI TAKASHI
IPC: H03G3/30
Filed: 1994-11-15
Abstract: In the transmission circuit, part of the output signal of the transmission circuit is derived by an output monitor circuit, and, after being subjected to envelope detection by an output detector circuit, the output signal of the output detector circuit is inputted to a peak hold circuit successively holding the peaks of the input signal, so that varying amplitude components are removed, and a DC value is detected. An error detector circuit compares the detected value with a reference signal generated from a reference signal generator circuit, and the error signal is used as a gain control signal to control the gain of a power amplifier circuit.

Inventor: COUTRURE PIERRE
IPC: H02K29/10
Filed: 1993-07-06
Abstract: The electric motor-wheel has an entry (40) to receive current at terminals (15) and three outputs (42) for three alternate phase currents. The currents may be polyphase. A microprocessor (44) has branches (41a,41b,41c) to control the operation and is external to the motor-wheel. A stator feeds the electric current. The stator (6) is in the shape of a cross with three arms for the phase currents and a fourth arm (13). A condenser (14) distributes to the three condensers on the arms and the microprocessor is connected to the fourth arm. The motor-wheel has two distribution output buses and a circular supply (48) connected to the arms for a high-voltage current. A rotor coaxial with and rotatably mounted about the stator has a conversion system for converting an electric input current into a variable alternating electric current and also has power electronics in the hollow portion with input terminals to receive the electric current and output terminals to generate the variable alternating electric current. The variable alternating current is supplied to the stator windings.

Title: Spring snap clip
Inventor: VAN LEEUWEN MARTIN
IPC: F16B5/06
Filed: 1995-04-18
Abstract: A snap spring clip (10) supports conduit, cables, and the like from a structure and has a C-shaped body (11) with one end of the body cooperating with the other end to form a restricted opening (14) into which such conduit, cables and the like may be snapped.   The one end of the body may be formed with a reversely flared lip (13) while the other end is folded back on itself to form a U-shape clasp (16), the outer leg (19) of the clasp being in the form of a more narrow finger extending generally parallel and adjacent the inner leg (17).  The finger is somewhat longer than the inner leg and extends midway between barbs (20, 21) struck from each edge of the inner leg.  The U-shape clasp is formed with a flattened bulb  (18)  providing sufficient area to push the clip to a locking position with the finger extending through a hole.  Once in the hole, because of the configuration of the fold, and the relative size of the hole and finger width, the clip is locked in place.

Patent CA-2149741-A1 (CA)
Inventor: HARTLEY WILLIAM R
IPC: B21D39/02
Filed: 1995-05-18
Abstract: A device for prehemming at least a portion of an upstanding flange of a sheet metal panel which has a tapered roller which is moved into engagement with the flange while moving the roller along the flange with its axis of rotation disposed in a path which is substantially parallel to the fold line of the flange along the periphery of the panel.  The roller is journalled for rotation on an arm pivotally carried by a slide which is moved by a drive cylinder along a lineal path generally parallel to the fold line of the portion of the flange to be prehemmed.  As the slide moves linearly the arm is pivoted to move the roller transversely by a follower carried by the arm and received in an elongate cam track having a portion contoured to impart pivotal movement of the arm to cause the roller to follow the desired path of  travel  substantially parallel to the fold line of the flange for prehemming the flange by bending it to an acute included angle relative to an adjoining portion of the panel.

Title: Map data based position correction for vehicle navigation system
Inventor: KAO WEI-WEN
IPC: G01C21/00
Filed: 1994-01-03
Abstract: A vehicle navigation system is used to determine the absolute position of a vehicle with improved accuracy on freeways or rural highways. First, the system stores a known vehicle position in its memory. As the vehicle moves away from the known position, the system uses a variety of means (12, 14, 16, 18) to sense external signals. These means include satellite transmission receivers (18) and magnetic compasses (16). When a change in the external signals occurs, the system recognizes the presence of a landmark which can then be used to set the vehicle's position. To accomplish this, the system's data processor (20) searches a map data base (30), attempting to fix the position of the sensed landmark with respect to the initially stored known position. When the system identifies the most likely landmark, the position of the vehicle is then reset to that position.

Abstract: PCT No. PCT/IT93/00030 Sec. 371 Date Jul. 24, 1995 Sec. 102(e) Date Jul. 24, 1995 PCT Filed Mar. 31, 1993 PCT Pub. No. WO94/17976 PCT Pub. Date Aug. 18, 1994In the process for making plastic laminates a stack of prepreg bodies is provided with electrically insulated rigid flattening sheets between each pair of adjacent prepreg bodies. Two continuous metal bands are passed in a serpentine manner back and forth through the stack from one side to the other, while being spaced from each other, so that each metal band contacts only one side surface of each prepreg body and the bends formed in each of the two metal bands are distributed on opposite sides of the stack. After the stack is formed with the metal bands passing through it, an electric current is passed through both metal bands from one end of each band to its opposite end to heat the two metal bands and thus the prepreg bodies and pressure is applied to the stack. After heating and pressing the stack, the two metal bands are cut through at the bends to form the plastic laminates.

Title: Mirror assembly powered into rearwardly folded position against reversing spring bias
Inventor: BODDY IAN
IPC: B60R1/06
Filed: 1994-08-05
Abstract: A rearview mirror assembly comparing a fixed support structure (12), a movable mirror housing structure (14) having a movable mirror unit adjustably mounted therein, and a spring-biased mounting assembly (16, 18, 20, 22) mounting the movable structure on the fixed structure for spring-biased movement into a normal operating position. The movable structure responds to unwanted forwardly directed forces by travelling out of the normal operating position through a forward range of movement and by returning to the operating position upon release of the forces. Rearwardly directed forces cause movement through a rearward range of motion to an intermediate position, where the spring-bias decreases to zero, and thereafter cause movement of the structure, under a reverse spring-bias, to a rearwardly folded position. A power-driven assembly is provided for applying a yieldable force pattern to the movable structure to overcome the spring bias within the rearward range of movement to selectively move the movable structure between the operative and rearwardly folded limiting positions.

Title: Three Dimensional Graphical Display of Information
Inventor: COX KENNETH CHARLES
IPC: G06F3/0484
Filed: 1996-03-12
Abstract: A method and apparatus for the three dimensional graphical display of information. Information is displayed as nodes and arcs connecting nodes. The nodes and arcs are displayed with their three dimensional characteristics used to encode data attributes. In one embodiment, the nodes and arcs represent geographic network data and are displayed on a representation of a globe. The height of the arcs above or below the surface of the globe encodes a link attribute of the data, while the height of the nodes above or below the surface of the globe encodes a node attribute of the data.  Three dimensional characteristics of the nodes and arcs other than height may also be used to encode data attributes. In addition, the three dimensional representation of the data allows for novel thresholding techniques, such as drawing certain nodes and arcs below the surface of the globe and using the globe as a clipping surface.  User interaction is also enhanced, for example by allowing users to interactively manipulate the clipping surface as well as the three dimensional display characteristics of the nodes and links.
