  • Automatic re-initialization of resonant sensors in rocket and missile guidance systems
    Patent number: 8563909
    Abstract: An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.

  • Method and system for delivering redeeming dynamically and adaptively characterized promotional incentives on a computer network
    Patent number: 6915271
    Abstract: This invention relates to a system and method for defining, electronically distributing, dynamically displaying to a consumer, redeeming and clearing promotional incentives over a network. One or more parameters of the incentives may be dynamically determined by being dependent on one or more characteristics of the consumer including the location on the network where the incentive is being viewed.
