Abstract: A turf aerator includes a frame, a tine shaft rotatably supported by the frame, a plurality of tines coupled to the tine shaft, a swing arm supporting the plurality of tines, and an input. The swing arm being rotatably supported by the frame and configured to rotate the plurality of tines between an operating position and a retracted position. Actuation of the input (i) actuates the swing arm to transition the plurality of tines from the retracted position to the operating position and (ii) activates the tine shaft to move the plurality of tines.

Abstract: A turf aerator includes a retracting tine assembly and an input mechanism. The tine assembly includes a plurality of tines, a pair of swing arms, and a linkage for selectively moving the pair of swing arms and the plurality of tines from the operating position to the retracted position. The pair of swing arms support the plurality of tines and are configured to rotate the plurality of tines between an operating position to a retracted position. The input is coupled to the linkage and the input is operable to active the linkage to move the pair of swing arms and the plurality of tines from the operating position to the retracted position.

Abstract: One embodiment of the present invention provides a system that electronically aligns mini-bars on different semiconductor chips which are situated face-to-face to facilitate communication between the semiconductor chips through capacitive coupling. During operation, the system measures an alignment between a first chip and a second chip. The system then selects a group of transmitter mini-bars on the first chip to form a transmitter bit position based on the measured alignment. In this way, the system allows a data signal to be distributed to and transmitted by the mini-bars that form the transmitter bit position. The system also selects a group of receiver mini-bars on the second chip to form a receiver bit position based on the measured alignment. Next, the system associates transmitter bit positions on the first chip with proximate receiver bit positions on the second chip based on the measured alignment.

Abstract: A memory system (30) for storing and delivering instructions to a central processing unit (14) in a data processing system includes a main memory (32), a buffer memory (35) and a control unit (42). The main memory includes a series of memory slots (34), each memory slot storing one track. Each track consists of a sequential list of instructions which are executed in order unless a jump instruction is encountered. Each track ends with a jump instruction and begins with an instruction which is a target instruction of at least one jump instruction. The control unit copies each track into the buffer memory prior to delivering instructions from that track to the CPU. This buffer has a pointer (40) which specifies the next instruction in the buffer to be examined. If the instruction is a non-jump instruction, it is delivered to the CPU.
