摘要： The disclosure is generally directed toward vehicle support systems. In one embodiment of the invention, first and second support assemblies can be pivotally coupled to a base. A control mechanism can couple the first and second support assemblies together and be configured to control pivotal movement of the support assemblies between spread and stowed positions. In another embodiment, first and second support assemblies can be pivotally coupled to a base and to first and second wheel assemblies. First and second steering mechanisms can be coupled to the first and second wheel assemblies and the first and second support assemblies. A control system can be operatively coupled to the first and second steering mechanisms and can be configured to command selected angular positions of the first and second wheel assemblies relative to the base by compensating for the support assemblies being in various positions.

摘要： Apparatus and method for providing downlink frames to be transmitted from a spacecraft to a ground station. Each downlink frame includes a synchronization pattern and a transfer frame. The apparatus may comprise a monolithic Reed-Solomon downlink (RSDL) encoding chip coupled to data buffers for storing transfer frames. The RSKL chip includes a timing device, a bus interface, a timing and control unit, a synchronization pattern unit, and a Reed-Solomon encoding unit, and a bus arbiter.

摘要： An uplink controlling assembly speeds data processing using a special parallel codeblock technique. A correct start sequence initiates processing of a frame. Two possible start sequences can be used; and the one which is used determines whether data polarity is inverted or non-inverted. Processing continues until uncorrectable errors are found. The frame ends by intentionally sending a block with an uncorrectable error. Each of the codeblocks in the frame has a channel ID. Each channel ID can be separately processed in parallel. This obviates the problem of waiting for error correction processing. If that channel number is zero, however, it indicates that the frame of data represents a critical command only. That data is handled in a special way, independent of the software. Otherwise, the processed data further handled using special double buffering techniques to avoid problems from overrun. When overrun does occur, the system takes action to lose only the oldest data.

摘要： A linkage mounted counterweight for offsetting a load at the free end of an articulated boom crane (20). The articulated boom crane (20) includes an articulated boom (23) that includes an elevate linkage (25) and a telescoping section (24) is disclosed. The elevate linkage (25) includes a lower section (42) and a mid section (44). The counterweight (60) is located on the lower section (42) near where the lower section (42) is hingedly attached to the base of the crane (20). As the articulated boom (23) is raised from a stowed position, the counterweight moves away from the tilting fulcrum (F) of the articulated boom crane (20) to assist in maintaining the stability of the crane.

摘要： A vehicle with a variable-length wheelbase is disclosed. The vehicle of one embodiment has a first body portion coupled to a first set of wheels and a second body portion coupled to a second set of wheels to define a vehicle wheelbase. The first and second body portions are moveable relative to each other in a direction substantially parallel to a longitudinal axis of the vehicle, so as to move the base between extended and retracted positions. When the base is in the retracted position the vehicle's wheelbase has a first length, and when the base is in the extended position the wheelbase has a second length greater than the first length. A boom is pivotally coupled to the base. The boom moves toward a lowered position when the base is moved toward the extended position, and the boom moves toward a raised position when the base is moved toward the retracted position.
