  • Patent number: 7590461
    Abstract: A production planning method inputs demands for products. The demands have multiple due dates, and the multiple due dates have different priorities. The method performs an explosion process utilizing linear programming and heuristics to identify demands for components that are used to make the products (the explosion process maintains the multiple due dates and corresponding priorities for the components) and performs an implosion process utilizing linear programming and heuristics to assign resources to the components considering the multiple due dates and corresponding priorities.

  • Publication number: 20080221962
    Abstract: The invention disclosed comprises a method for encouraging fair sharing of limited material inventory and capacity between multiple customers when creating a production plan the invention allocates resources among competing demands in a linear programming production planning system by first classifying the demands into fair share sets, wherein all demands within each set have the same priority, calculating the cumulative demand for each resource within each set, and then allocating the resources to the demands in order of fair share set priority. If, during the allocating process, the supply of a given resource cannot satisfy a given cumulative demand of a given set, the given resource is allocated proportionally (e.g., evenly or according to usage proportions) among all demands that contribute to the given cumulative demand within the given set. This is an advanced planning system for optimizing established planning objectives (e.g.

  • Patent number: 7380625
    Abstract: A vehicle engine compartment hood is provided for a vehicle body having a hood opening. A hood panel normally closes the engine compartment. A hood base panel underlies the hood panel and is pivotally mounted on the vehicle body for pivotal opening movement to lift the hood panel and allow access to the engine compartment through the hood opening. A mechanism acts between the hood panel and the hood base panel for selectively elevating the hood panel above the hood base panel and the hood opening when the vehicle is in a pedestrian rich environment. The mechanism absorbs energy when an impact is received against the hood panel.

  • Patent number: 7369928
    Abstract: A headrest positioning system for automatically adjusting the position of a headrest of a vehicle seat. The headrest can be a power headrest that is part of a power seat system, where the position of the headrest can be preset by a seat occupant with the other positions of the seat in a memory function. The system includes a seat occupant sensing system that senses the position of the seat occupant's head, eyes or other facial features to determine a desired position of the headrest. The system compares the actual position of the headrest to the desired position, and automatically adjusts the position of the headrest to the desired position. In one embodiment, an imaging system determines the position of the seat occupant's head. In another embodiment, the system determines the position of seat occupant's eyes based on the position of the driver side mirror.

  • Patent number: 7334656
    Abstract: A hood elevation system for a vehicle includes an actuator configured to selectively move at least a portion of a vehicle hood between an elevated and a retracted position. The hood elevation system also includes a self-locking mechanism configured to allow movement of the hood between the elevated and retracted positions initiated by the actuator, but to resist retraction of the hood as a result of certain loads applied to the hood. The self-locking mechanism thus enables repeated elevation and retraction of the hood. In a preferred embodiment, the self-locking mechanism is configured to deform, thereby absorbing energy from an impact to the hood.
