Patent EP-0511768-A2 (EP)
Inventor: SHEENAN RONALD T
IPC: A01D41/14
Filed: 1992-04-21
Abstract: An agricultural harvesting machine (10) having a cutting element (22) movably supported thereon is provided with a height sensor (114) including a transmitter and a receiver mounted for movement with the cutting element. The transmitter (114) directs bursts of sound waves in the range of about 5KHz toward the ground and echoes of the bursts are picked up by the receiver, the elapsed time between transmission and reception being an indication of the height of the cutting element above the ground. To distinguish between echoes of the bursts and environmental noise picked up by the receiver, the bursts are encoded by transmitting them in pairs, the bursts of a pair being of fixed duration and separated by a fixed interval of time. The duration of each signal and the time spacing between signals is checked and if they are not of the correct duration or are not separated by the fixed interval of time they are rejected as noise. The time between transmission and reception of a burst is measured to provide an indication of the height of the cutting element. The measured height is compared with a reference or desired height and the difference value is used to control movement of the cutting element to the desired height. 
     There is also enclosed an implement, such as a cutterbar (22) on an agricultural harvesting machine (10), which is automatically position-controlled to maintain a reference position relative to the ground surface. The implement (22) is mounted so that it may be raised, lowered or tilted and the control is such that tilting movements are preceded by, or are carried out concurrently with, a raising or lowering movement when one end of the implement is at the reference position and the other end is between the reference position and the ground surface. Manually operated UP and DOWN switches (332,336) not only control up and down movements of the implement but also inhibit and restore automatic control of implement positioning. A set/reset switch (340) enables manual selection of a predetermined reference position or the selection of the present implement position as the reference position.

Abstract: A semiconductor memory device has a plurality of memory cell arrays (12a,12b); input and output sections (11a, 11b) each provided so as to correspond to each of the memory cell arrays; and an allocating section (17) provided between the memory cell arrays and the input and output sections, for allocating one of the memory cell arrays to one of the input output sections in ordinary mode, and a plurality of the memory cell arrays to one of the input and output sections in test mode. In the operation test mode, since only a part of the input and output sections are used, it is possible to decrease the number of chips connected to the I/O pins (whose maximum number is limited) of the tester so as to be testable simultaneously, so that the number of chips whose operation tests can be implemented simultaneously can be increased, thus reducing the time required for the operation test of the memory device as a whole.

Abstract: A protocol and associated addressable shadow port circuitry for efficiently extending serial bus capability to the backplane environment is disclosed. The protocol is designed to co-exist and be fully compatible with existing serial bus approaches. Circuitry and a protocol operable to couple any one of the boards (BOARD1-BOARDN) on the system backplane bus to the serial bus master (SBM) is described, wherein the protocol operates to select and deselect the boards without interfering with the normal operations on the system backplane bus. The protocol and circuitry is extended to hierarchically arranged systems, so that a primary serial bus master (SBM) device can selectively access and communicate with any device positioned at any level of the hierarchy. Further disclosed embodiments utilize multiple remote serial bus masters on hierarchically arranged networks, each remote serial bus master being coupled to a primary serial bus master using the protocol and circuitry of the invention, so that autonomous testing may be performed by the remote serial bus master devices under the control of the primary serial bus master.

Abstract: An inverse discrete cosine transform ("IDCT") implementation specifically for the decompression of JPEG, MPEG and Px64 encoded image and video data uses a preprocessing step embedded in a Huffman decoding process (12) to classify data blocks prior to computing the IDCT. The use of data block classification (70), along with the use of pruned IDCTs appropriate for the specific block class, reduces the total number of multiply and addition operations necessary to decompress an encoded data block, and thereby allows faster data decompression. Synthesis of coefficients suitable for multiplication allows efficient implementation of the novel decompression technique in typical microprocessor architectures, including RISC processor architectures.
