Abstract: The present invention concerns a method of and apparatus for storing to and accessing from a memory device, one or more voxels of a beam disposed along one or more of a plurality of storage/retrieval directions of a 3-D matrix array and 3-D discrete voxel space. Voxels are stored into memory space by mapping the voxels along one of the plurality of storage/retrieval directions, into a plurality of independently successful memory modules in memory storage space. Each memory module is indexed by a memory module index and has internal memory cell addresses. The mapping is carried out in accordance with a linear skewing function which expressed in terms of x, y, and z coordinate directions and integer n. The voxels can be retrieved along one or more of a plurality of storage/retrieval directions by de-mapping one or more of the voxels from the memory storage space into 3-D voxel space using spacial parameters and integer n. The demapping operations of the present method are also used in order to determine the voxel depth measures of voxels along one of the storage/retrieval directions. 5, a

Abstract: An apparatus and method are described for defining a small interrogation volume in a liquid sample suspected of containing an analyte. The apparatus and method utilize a dual optical fibre probe (10) constructed with the ends of the optical fibres (12,14) at the liquid/fibre interface spatially oriented such that the intersection of their longitudinal axes forms an included angle ranging from about 40° to 140°. By appropriate choice of the numerical aperture and core diameter of the optical fibres and the separation distance between the longitudinal axes of the optical fibres at the liquid/fibre interface, a finite interrogation volume of predetermined size and independent of the total liquid sample volume can be defined. The apparatus and method substantially reduce background interference with corresponding increase in assay sensitivity.

Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (5) (also called hand or end effector) of the manipulator (1) are measured by a force-mement sensor (4). The resulting force and moment signals are scaled and fed as input voltages to motors (26,34,51) in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.

Abstract: A test arrangement for printed wiring boards or the like employs a scanned laser beam which impinges upon a photoemissive grid mounted close to the board under test. The laser beam causes the grid to locally emit electrons which are attracted toward the board due to an electric field between the grid and a conductive plane behind the board. The spacing between the grid and the workpiece is very small so the electron beam is very localized and travels a short distance; there is no need for deflecting the electron beam, because it is the laser beam which is scanned. The charge transferred from the grid to the part under test by electron flow is detected and correlated with the position of the beam to provide an indication of the status of the conductive pattern. Undesired shorts or open circuit conditions among the conductors on the board is determined by comparing the charge transfer as a function of beam position with the desired standard pattern produced by a fault-free board.

Abstract: A frequency-hopping packet communication system without a master clock or master control unit is based on use of a receiver's frequency hopping timing and identification to control communication. A frequency-hopping band plan, involving the number of channels and the pseudo-random pattern of frequency change and nominal timing of changes, is universally known to each node in the network. A transmitter acquires synchronization with a target node by use of information previously received from or about a target indicating timing of present idle frequency hop of the target receiver. Each receiving node establishes in each station or node a table of receiver frequency hopping sequence offsets (hop timing offsets) of each other node-within its communication range, and each node announces its presence on each frequency in a packet with a hop timing offset indicator. The hop timing offset indicator is a key used to read a table to allow nodes to set themselves in synchronization with one another. A location indicator built into the address of each packet is used to randomize an ordered frequency-hopping table at each node. Frequency-hopping is implemented by the division of communication slots and the accumulation of slots into epochs, wherein each epoch equals the total number of available slots (number of channels times the number of time frames per channel). The transmitting node tracks the pre-established frequency-hopping pattern for its target receiver based on previously-acquired information.

Abstract: A memory apparatus includes a memory cell array for storing a data, a shift register for receiving an input serial data to be stored in the memory cell array and supplying an output serial data to be read from the memory cell array, and a transfer gate for transferring a data in parallel between the shift register and the memory cell array. In the shift register, the input serial data is shifted to an output side thereof until the first bit reaches to the final step thereof. Then, the input serial data is transferred to be stored in the memory cell array by the transfer gate. Thus, when the stored data is read therefrom, no invalid bit is supplied even at the beginning time even if the shift register is longer than the input serial data.
