  • Patent number: 6837816
    Abstract: A motor-integrated transmission mechanism for use in parallel hybrid electric vehicles. The transmission can provide five basic modes of operation that can be further classified into sixteen sub-modes: one electric motor mode, four engine modes, four engine/charge modes, three power modes and four regenerative braking modes. Each of these sub-modes can be grouped into like clutching conditions, providing the functional appearance of a conventional 4-speed automatic transmission, with electric launch, engine-only, engine/charge, power-assist, and regeneration capability. CVT capability is provided with one of the engine/charge modes. The transmission can be incorporated in front-wheel drive and in rear-wheel drive vehicles.

  • Patent number: 6592484
    Abstract: Disclosed is a novel parallel hybrid transmission that transmits torque from two power sources to the drive wheels of a vehicle. The transmission functions with a single heat engine and a single electric motor/generator. Through the use of a compound planetary gear train and four automatically controlled clutches, the transmission is able to (i) sum torque from the two power sources to drive the vehicle; (ii) split torque from the heat engine to drive the vehicle and charge the batteries; (iii) transmit torque individually from either of the two power sources; and (iv) operate as a one- or two-degree-of-freedom mechanism. The configuration of clutches and the compound planetary gear train enable thirteen modes of operation, namely, one motor-only mode, three combined motor and engine modes, one continuous variable transmission/charging mode, four engine-only modes, and four regenerative braking modes.

  • Patent number: 5329701
    Abstract: A tool is used to custom fit rubber slip-ons onto golf shoes for use in wet conditions to keep the feet of the golfer dry. The tool can be manually manipulated to cut openings into the sole of a slip-on of an appropriate size so that the openings are aligned with the spikes of the golf shoe. When openings have been cut for all of the spikes, the sole of the slip-on rests against a base of the spikes and the sole of the golf shoe. The tool has an elongated hollow body with two ends. One end has a circular cutting edge thereon and the other end has a handle thereon. After the slip-on is placed onto the golf shoe with the spikes separating the sole of the slip-on from the sole of the golf shoe, the tool is aligned with each spike in turn to cut an appropriate opening for that spike. Previously, slip-ons have been designed with pre-cut openings but these slip-ons can only be used with a specific model of golf shoe of a specific manufacturer having a specific size.

  • Patent number: 5190153
    Abstract: A holder for storing compact discs where each disc is contained within a conventional disc container uses a housing and anchoring means for the housing. The anchoring means is used to mount the housing in a motor vehicle. The housing contains partial partitions that are sufficiently large to hold said containers in a spaced apart parallel relationship from one another extending from front to rear of said housing when the disc containers are inserted into the housing through the front. The housing has retention means for each container to hold the containers within the housing when the containers are oriented with the groove towards the rear wall and towards the retention means. The retention means contacts a groove of each disc container and holds said container in said housing until the container is pulled out of said housing so that the retention means automatically releases itself from said disc container.
