Abstract: A satellite communications system (10) that employs an array of separate and easily deployable antennas (12) for transmission and reception purposes to accommodate high data rate transmissions. The antennas (12) can be deployed randomly at a communications site and are physically separated. Each antenna (12) transmits and receives the same information. A coded signal is used to identify the transmission from each antenna (12) for calibration purposes to align the bits transmitted by each antenna (12) and provide carrier frequency phase matching. The coded signals are used to compare the phase and timing relationship between each antenna signal and a reference antenna signal when the separate antennas receive all of the coded signals. Correction computations are performed and specialized phase and data alignment systems (24, 32) are employed to delay and adjust the phases of the various transmitted signals relative to the reference antenna (12) to provide the desired alignment.

Abstract: A processing engine (10) that generates sum of products (SOP) values for incoming data. The processing engine (10) includes a calculation module (30) for generating intermediate and SOP values based on the incoming data and coefficient values, wherein the intermediate values are defined by product values and partial presum values. A feedback module (50) stores the intermediate values until the calculation module (30) generates SOP values. The processing engine (10) further includes a reordering module (70) for reordering the SOP values. The feedback module (50) includes a switching mechanism (52) for retrieving intermediate values from the calculation module (30) until the calculation module (30) generates SOP values. Thus, a feedback RAM (53) can store the intermediate values without the need for buffering RAM at the input stage.

Abstract: An amusement ride that simulates the sport of drag racing. The ride includes a vehicle propelled by a compressed fluid system. They compressed fluid system includes a pressure sleeve slid over and receiving pressure from a pressure tube. The vehicle is attached to the pressure sleeve such that pressure entering the pressure sleeve through the pressure tube from a pressure source causes separation of the pressure tube and pressure sleeve thereby moving the vehicle. The compressed fluid system further includes a main dump valve operative to supply pressure to the pressure tube on demand. Accordingly, the release of pressure into the pressure sleeve causes the vehicle to rapidly accelerate and simulate the sport of drag racing.

Abstract: A system for the thermal imaging of sonically or ultrasonically excited subsurface defects in a structure. The system includes a hand-held sound source, a thermal imaging camera and a control unit. The sound source emits pulses of sound energy into the structure, and the camera generates images of defects in the structure that are heated by the sound energy. The control unit controls the operation of the sound source on the camera for timing purposes. The sound source includes a transducer that is positioned against the structure at a desirable location. The source further includes a pair of legs that are also positioned against the structure to define a plane in combination with the transducer. The length of each leg is adjustable relative to the length of the transducer so that the gun can be used against irregular surfaces. The legs include a rubber tip to further prevent the transducer from slipping on the structure.

The warning light is integrated into a first decorative cover member and may be connected to the vehicle turn signal circuit by way of connectable electrical leads or by an integrally formed plug and outlet arrangement. A second decorative cover member may be substituted for the first decorative cover member when it is not desired to incorporate the warning light.

Abstract: A vehicle side mirror that includes a forward scalp portion selectively removable from a forward side of the mirror housing. The scalp portion can be replaced with an extended auxiliary towing mirror scalp that conforms with the housing of the side mirror, and provides an extended auxiliary mirror attached thereto that is suitable for providing extended side viewing for towing purposes. In one particular embodiment, the towing scalp is interchangeable with an auxiliary turn signal light scalp to allow the towing vehicle to be readily converted to a suitable towing situation. In alternate embodiments, the towing mirror is slidably extendable from a support panel associated with a side mirror, or the tow mirror is pivotally extendable from a bottom surface of the side mirror.

Abstract: A mirror assembly in which the mirror housing and multi-function backing plate provide various useful functions. The multi-function backing plate supports not only a conventional reflective element but also supports a wide angle reflective element. The wide angle reflective element may be adjustable. The multi-function backing plate supports an indicator light assembly so that the mirror assembly can provide an indicator light function. The multi-function backing plate also support a recessible spot or approach lamp which, when the mirror is in an operative position, is recessed within the housing. When the mirror is in an inoperative state, the multi-function backing plate can be rotated so as to expose the spot or approach light. Various light pipe configurations enable transmission of light projected from a light source mounted to and behind the multi-function backing plate to project light through the light pipe externally to the mirror housing to provide an indicator light function.

Abstract: A sensor carrier assembly for supporting one or a plurality of sensors to facilitate mounting the plurality of sensors to the vehicle. The sensors are mounted to a carrier or mounting beam which is then in turn mounted directly to the vehicle. The mounting beam mounts directly to the vehicle and a bumper covers the mounting beam. Alternatively, the sensor mounts externally to a vehicle body part, such as a bumper. Fastening points for attaching the carrier assembly to the vehicle are preferably placed in proximity to the sensors to assist in maintaining proper orientation of the sensors.
