Title: System and method for adaptive brake application and initial skid detection
Inventor: SALAMAT BIJAN
IPC: B60T13/74
Filed: 1998-05-01
Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

Title: Deployable, expendable or recoverable floating radar reflective device
Inventor: BARKER DENIS
IPC: B63B22/16
Filed: 1998-10-08
Abstract: This invention is an easily deployable, expendable or recoverable floating radar reflective device. The invention can be built with sufficient reserve buoyancy to allow the fitting of a number of optional devices, such as a GPS transceiver or lighting. Thus, the device can be used for a variety of applications including: man-overboard marker, radar testing, temporarily marking submerged objects or navigation points, search and rescue, naval gunnery practice and/or weapons testing, or any other application that requires a floating reflective station. The device is constructed of aluminum, and consists of an internally supported tetrahedron shape with a floatation pod with an integrated radar reflector at each apex. The tetrahedron shape allows the device to roll due to the motion of the waves or the method of deployment, and always present the same shape and reflective area as a target for radar, or as a support for optional devices mounted on the structure. Each floatation pod is fitted either with scuttling devices, to cause the device to sink if recovery is not a preferred option, or plugs if recovery is required. The use of dissimilar metal in the scuttling devices and the pins that hold the device together allows the device to rapidly corrode once it sinks, alleviating environmental concerns. The device is collapsible for ease of storage, and can be either assembled by hand, or deployed automatically, depending upon usage requirements.
