  • Publication number: 20050208931
    Abstract: Embodiments of interruption-sound devices for producing an interruption sound signal in a telecommunications transmission signal comprising a signal generator circuit and a processor circuit, in accordance with the present invention. The interruption sound signals are input into the appropriate location of the telecommunications device such that the interruptee perceives characteristic sounds such as those encountered when a mobile phone is about to drop a call. As a result, the interruptee will place blame for call disconnection on the mobile-phone technology and not on the interruptor. The interruption-sound device is suitable for incorporated into an external interruption module, a landline phone, and a mobile phone.

  • Publication number: 20050093330
    Abstract: Embodiments of the present invention provide power drives comprising a drive unit, a drive cable, a trolley, and a track on which a trolley is guided for moving components for use in motor vehicle applications. The drive unit comprises a gear powered by an electric motor. The electric motor rotates the gear that meshes with and advances the drive cable. The drive unit is coupled to an end of the track by an intermediate cable sleeve comprising a flexible material allowing for independent placement of the drive unit and the track by selectively bending the intermediate cable sleeve. The drive cable passes through the intermediate cable sleeve and is coupled to the trolley and is adapted to advance the trolley along the track. The electric motor causes the gear to rotate in a forward or reverse direction to advance the trolley along the track.

  • Publication number: 20050082869
    Abstract: The present invention provides a power assisted cover actuator for operating a tonneau cover for an open bed of a truck, such as a pickup truck. The cover is hingably coupled to a distal end of the truck bed adjacent the truck cab. The power assisted cover actuator in accordance with an embodiment of the present invention comprises a track upon which a trolley is guided by a linear actuator. An end of an arm is pivotally coupled to the trolley and the cover. The linear actuator comprises a motor driven drive rod coupled to the trolley that extends to advance the trolley along the track from a lower position to a higher position which raises the arm to push the cover open. Retracting the drive rod reverses the direction of travel of the trolley from a higher position to a lower position lowering the arm and closing the cover.

  • Publication number: 20050018413
    Abstract: An illuminated remote control device providing illumination in the visible spectrum and the functionality of a wireless signal transmitter. Light projects from one or more translucent portions of the remote control device. The illuminated remote control device comprises a housing defining an outer surface and a cavity therein. The housing comprises at least one translucent portion adapted for the transmission of light from the cavity to the outer surface of the housing. At least one control feature is provided to operate transmitter electronics and/or the light source housed in the cavity. The light source produces light within the cavity, the light being then guided from the cavity to the surface by a translucent portion of the housing. The illumination provides the user with an increased ability to see or be seen in the dark and provides illumination that is visually appealing.

  • Patent number: 6719077
    Abstract: A hood-latching system for a vehicle that has an engine-compartment hood that can be moved between a closed position and one or more open positions. The hood-latching system comprises one or more novel hood latches that are operable, when secured in a latched state to apply hood retention forces to the engine-compartment hood and thus, to secure the engine-compartment hood in its closed position. The novel hood latches of the hood latching system comprise prop legs that support the novel hood latches out of a path of travel of the engine-compartment hood when the novel hood latches are not secured in a latched state. The prop legs of the novel hood latches, thus, enable one person to close the engine-compartment hood of the vehicle without pinching the novel hood latches between the engine-compartment hood and latch-anchor components to which the novel hood latches are mounted.

  • Patent number: 4971172
    Abstract: In a hood for a conventional highway truck, induction air for the engine of the truck is drawn by the engine vacuum into the hood through air inlets therein at the upper corners of the grille opening defined by the front hood reinforcement to avoid the more severe road splash contamination. The air is drawn through several turns of ninety degree or smaller angle, including the inlets disposed perpendicularly to the path of travel, through a vertical duct adjacent the front reinforcement, a horizontal duct adjacent the fenders, a rear vertical duct, and the duct-defining rear reinforcement to a connection with the engine air cleaner. Both of the vertical ducts are provided with small drain holes adjacent their lower ends to permit heavier particles and water to drain therefrom. The ducts have been provided with large cross-sectional areas which, in addition to reducing air flow restriction, provide lower air flow velocity which further enables water and heavier particles to drop out of the air stream.

  • Patent number: 4566552
    Abstract: A hood tilt retardation system comprising a shock absorber mounted on the side of upstanding member near the motor truck engine provides cushioning of the hood descent into its fully open or closed positions in the final segments thereof. This cushioning is augmented by a pair of springs attached to the hood and upstanding member for movement thereabout and functioning as a counterbalance to the hood weight during the hood reciprocal movement between its open and closed positions.
