摘要:
A polygon sort engine including first and second apparatus for sorting. The first apparatus for sorting receives planar, externally convex polygon vertices from an external polygon tiling engine. This includes points and lines. The state machine on the second apparatus for sorting interfaces with the polygon tiling engine and a raster engine in a graphics pipeline. It provides a control signal which determines when the first apparatus for sorting will receive the next polygon. The second sorting appartus also controls whether the polygon is stored in the PING or PONG memory. For example, as the state machine is controlling the sorting of the current polygon into the PING RAM, the state machine will also be controlling the loading of the previous vertices and the PONG RAM into the raster engine.
摘要:
A bus interface controller for use in a digital information system. The bus interface comprises more than four bi-directional data channels which are multiplexed so as to accomplish switching of data from any channel to any or all of the remaining channels. The device is preferably embedded in a substate comprising gallium arsenide material and operates at a frequency of at least 25 MHz.

A polygon tiling engine for use in a computer graphics display system. The computer graphics display system includes a high speed processor which provides lines of vertices, object type codes and START and STOP points for the vertex lines. The system further includes a VME bus. An improved apparatus for polygon tiling comprises apparatus for receiving the START and STOP points, instruction register apparatus coupled to the high speed processor for receiving instruction codes, object storing apparatus, a state machine for controlling the polygon tiling apparatus, a polygon address generating machine, a user defined object memory, a multiplexer and a triple buffered memory. Information is sent from the high speed processor to the tripled buffered memory, instruction registers and START and STOP registers. The information is processed into polygon addresses by the polygon generating apparatus. The polygon tiling apparatus is capable of tiling terrain data, multivertex polygons and user defined objects. The user defined objects are preferably stored in a link list random access memory. The state machine controls the polygon address generator and receives instructions from the instruction register. User information is supplied on the VME bus. Tiled polygons are output to a polygon sort engine for further processing.

A vehicle coat hook assembly in which the coat hook is recessed into the header and is actuated to hanging and recessed positions by a simple push and release by the operator which linearly moves the coat hook to such positions. The actuation of the coat hook is controlled by a push-push mechanism.
摘要:
A retractable coat hook assembly comprising a coat hook moveably mounted to a mounting bracket secured to a vehicle roof. The coat hook has a base portion with opposing side walls. A pair of pins extends from each side wall and is received in corresponding grooves in the mounting bracket to rotate the coat hook downwardly about non-fixed rotational axis and translate the coat hook away from the bracket when the coat hook is moved from a retracted to an extended position.

An overhead console for a vehicle has a support structure (14) with walls (30, 80, 82, 84) and an access door (10) defining a compartment (78) for storing a remote transmitter (86). The transmitter (86) includes an actuator switch (92) that is normally manipulated by a user for operating the transmitter (86) to open a garage door, turn on lights, etc., from inside the vehicle. The console access door (10) is attached to the support structure (14) for movement between closed and open positions. A manually operable actuator (12) is engageable with the transmitter switch (92) for operating the transmitter (86) upon depression of the actuator (12). The actuator (12) is attached to the support structure (14) independent of the door (10) such that movement of the actuator (12) is at least substantially unaffected by movement of the door (10) between the closed and open positions. With this arrangement, the transmitter switch (92) and actuator (12) can be mutually aligned with the door (10) in the open position by positioning the transmitter (86) in the compartment (78) and adjusting the transmitter (86) with respect to the actuator (12).
摘要:
A vehicle coat hook assembly in which the coat hook is spring-biased to normally locate the hook closely adjacent to the header of the vehicle but which is extendable against the bias of the spring to provide more area for hanging a greater number of clothes hangers. In a preferred embodiment, a linearly movable stem is connected to the coat hook. In another embodiment, the coat hook is pivotally mounted.

A console and method of installing a console for a motor vehicle or the like including a passenger cabin. The console includes an accessory module for use by occupants of the vehicle and has a housing with fasteners adapted to mount the console within the vehicle cabin. A chamber having an open side is formed in the console and receives an accessory module. At least a portion of the housing comprises an expanded polymeric material, preferably expended polypropylene, to provide a soft surface within the vehicle cabin. A decorative skin covers a surface of the housing that confronts the vehicle cabin in another embodiment

A vehicle sun visor assembly includes a shaft configured for mounting in a vehicle. The shaft includes in-molded first and second electrical wires extending longitudinally along the shaft. The first and second electrical wires include corresponding first and second exposed contact surfaces spaced circumferentially about the shaft. The sun visor body is pivotally and slidably mounted to the shaft and includes first and second mating contacts positioned for selective engagement with the first and second exposed contact surfaces only when the sun visor is positioned at a predetermined pivotal and longitudinal position with respect to the shaft for providing electrical power to a vanity mirror or the like.
摘要:
A damper is snap-fitted in a mounting socket formed adjacent a door frame to engage the door for controlling the movement of the door between closed and open positions. In the preferred embodiment of the invention, the socket includes a first pair of spaced legs engaging one side of the damper at opposite ends and a centrally located leg engaging the side of the damper opposite the one side. In a preferred embodiment of the invention, the central leg preferably includes an inwardly projecting lip which extends over the top of the damper which rests on a floor extending from the side of the door frame for holding the rotary damper vertically in place.
