Abstract: Scanning beam apparatus adapted to display two views of a surface for stereoscopic viewing, wherein two series of electrical signals are obtained by scanning the surface with a normal and then tilted beam wherein alternate tilting of the beam is achieved by adjusting during alternate scans the currents flowing in the gun alignment coils (12) of the SEM so as to shift the beam, and simultaneously introducing an offset in the signals applied to at least one other element (14 or 16) in the beam forming and focussing assembly, to counteract the shift introduced by the alignment adjustment. The offset ensures that the point of intersection of the beam axes follows the focal plane as focus is altered. The two video signals may be correlated to produce a correlation signal whose value for each point in the surface indicates the apparent shift in position of that point as between the normal and tilted beam scans, to produce a signal indicative of the surface topography. The correlating signal may be converted to a focussing control signal and may be enhanced by a process of successsive approximations. Where the signals are to be displayed the two series of electrical signals may be supplied to a frame store (36) which includes a feedback loop and input feedback multiplying means (38, 40) forming a recursive filter, and a signal converter means (42) including an R B G look-up table memory means for generating R, G and B signals for display by a colour monitor (44).

Abstract: A method and system for efficiently accessing desired datasets among multiple datasets which are stored at specific data addresses within multiple storage systems (20-26) which are coupled to a host system (12) via a storage subsystem controller (18). A data request is transmitted from the host system to the storage subsystems via the data channel. The data request specifies non-address attributes for desired datasets, such as boundary addresses for large data extents including many datasets or a request for all datasets modified since the occurrence of a specified event. The data request is then processed at the storage subsystem controller (18) to determine a data address for each dataset within the storage system (20-26) which possess the desired attributes. Thereafter, the desired datasets are transmitted to the host system (12) in association with a specific address for each dataset. A selected status message is transmitted from the storage subsystem controller when no more datasets are located which posses the desired attributes.

Abstract: An apparatus and method for measuring the thickness of a tissue section with an automated image analysis system, preferably using polyploid nuclear DNA content, for use subsequent use in analyzing cell objects of a specimen cell sample for the diagnosis and treatment of actual or suspected cancer or monitoring any variation in the nominal thickness in a microtome setting is disclosed. An image of a measurement material, such as a rat liver tissue section, having known cell object attributes is first digitized and the morphological attributes, including area and DNA mass of the cell objects, are automatically measured from the digitized image. The measured attributes are compared to ranges of attribute values which are preestablished to select particular cell objects. After the selection of the cell objects, the operator may review the automatically selected cell objects and accept or change the measured cell object attribute values. In a preferred embodiment, each selected cell object is assigned to one of three classes corresponding to diploid, tetraploid and octoploid cell morphology and the measured DNA mass of the identified cell object fragments in the rat liver tissue section sample may be corrected. Next, the selected cell objects of the measurement material, e.g., DNA Mass, are then graphically displayed in a histogram and the thickness of the rat liver tissue section can be measured based upon the distribution.

Abstract: An ADRC encoder generates, regarding an ADRC block of 4x4 pixels, DR, MIN and quantized data corresponding to each pixel. A macro block formatting circuit generates code data DR, MIN and DT of four ADRC blocks. An adding circuit generates sum data (DR =DR1 + DR2 + DR3 + DR4, same calculation regarding MIN) of important data in the macro block. Mixing circuits insert the sum data into recording data as additional data. The sum data and the important data are distributed and recorded in plural channels. If one of the important data has an error and the remaining important data and the sum data have no error, the important data with the error can be completely corrected. Error correction of the important data and the quantized data generated by block encoding is effected with restrained increase in redundancy. Input data which has been reproduced and DCT-decoded is supplied to and is converted into 3x3 block format by a 3-line memory and block formatting circuit . An ADRC encoding circuit generates encoded data DTx of a center pixel data and data DT which is made up of peripheral 8 pixel data. A timing aligning circuit generates class information comprising 8 pixel data and the class information is supplied to a memory as a read address. Memory stores existing-range data and predicted data DTx^ through in-advance training. An error is detected by comparing the existing-range data and reproduced data DTx and when there is an error, predicted data DTx is selected. Error correction of received or reproduced image data is effected without using an error correction code.

Abstract: A system and method involving a statistical conditioning technique that improves the coding efficiency in compression systems which have unstable statistical properties by conditioning the probability estimate for a given model context on prior decisions for that context thus enlarging the conditioning decision set. Instead of extending the model context by increasing the range of prior decisions in the pixel neighborhood, each model context is expanded into a set of two contexts which are the actual coding contexts. For a given probability estimation model context, the selection of a coding context index is done on the basis of the previous coding decision (1 or 0) for that model context. Thus, if a model context is assigned an index A, the coding context would be assigned an index        2*A + D(A)'          , where D(A)' is the previous (immediately preceding) binary decision for model context A; the decision of which coding context to use turns on whether the model context was used most recently for coding a 1 or a 0. More generally, each model context index A is expanded into a set of 2**N coding context indices, where N is the number of previous decisions for model context index A used in the conditioning of, for example, an arithmetic coding decision. The addressing of the context expansion can be done in any way which expands the total number of contexts by a factor of 2**N. The index for a case where the expansion is by one decision bit may be        2*A + D(A)'          , whereas in the case where the expansion is by two decision bits the index may be        4*A + 2*D(A)' + D(A)''          .

Abstract: A method of controlling a transportation velocity of a printhead carriage of a serial printer is disclosed. The printhead carriage is driven by a motor via a timing belt. Firstly, a characteristic equation, which includes a motor speed, a current applied to said motor, an equivalent disturbance indicating environmental variations affecting said motor speed, is discreted. Thereafter, the equivalent disturbance is estimated using the characteristic equation which has been discreted. A value of the equivalent disturbance, which cancels the equivalent disturbance, is determined. Subsequently, a value of the equivalent disturbance is calculated using a discrete low pass filter. Finally, a current to be applied to said motor is obtained by adding a compensating level of the controller to the level of said equivalent disturbance.

Abstract: A disk player has a magazine for storing disks and a disk transport mechanism transporting a selected disk between a playback position outside the magazine and a store position located entirely within the magazine. The carriages are stacked upon each other and pivotally supported within the magazine. The carriages are extracted from the stack by lifting a front end of a carriage above a selected carriage. Subsequent to the lifting of the carriage, the selected carriage is withdrawn from the magazine to the playback position. When a selected carriage is moved to the playback position, the disks on carriages above and below the selected carriage are prevented from shifting with the removal of the selected carriage by coaxial opposing shafts which extend through spindle holes in the disks on the carriages above and below the selected disk. A closeable gap between the two shafts permits the selected disk to be shifted. The gap is closed, except when a carriage is being shifted into or out of the magazine, thereby preventing disks and their carriages from shifting due to vibration or tilting of the cabinet.

Abstract: A satellite (10) has two solar array panels (40,42) which are moveable between a closed configuration and an open configuration. The solar array panels are pivotably mounted on hinges (44,46) attached along the top and bottom of the satellite and extend outwardly from the top and bottom of the satellite in the open configuration. The height of the perimeter sidewall (14) is selected such that the satellite has a generally oblate configuration. Each solar array panel has a surface area substantially equal to that of the satellite cross-sectional area. The hinges (44,46) are mounted on pintles (48,50) extending from a solar array drive motor (58) which rotates the solar panel about the axis defined by the pintles to provide one axis sun tracking. The solar array panels are pivoted about the axes of the hinges until substantially parallel to the top and bottom of the satellite to form a compact, stackable configuration of the satellite for stowage. Three couplers (54A,54B,54C) positioned along the perimeter wall couple the satellite to similarly configured satellites within the fairing of a launch vehicle. The coupled satellites form a stack having three load-bearing columns consisting of the satellite couplers. In the stacked configuration, the couplers of one satellite are attached to the couplers of adjacent satellites by bolts restrained within non-explosive separation nuts (106). Pre-loaded compression springs (144A,144B) extend between the couplers of adjacent satellites. After the stack of satellites separates from the fairing (52), each satellite is successively deployed from the stack, starting with the top-most satellite. Deployment begins by activating the non-explosive separation nuts (106) in the couplers of the top-most satellite. Thereafter, the pre-loaded compression springs (144A,144B) extending between the coupling devices of the top-most satellite and the subjacent satellite (or, for the bottom-most satellite, the subjacent booster stage) accelerate the top-most satellite away from the stack and booster stage.

Abstract: A digital data processing device includes a bus (20) for transmitting signals (e.g. data and/or address information) between plural functional units (10,12,14,16,18) (e.g. a central processing unit and a peripheral controller). A first such unit includes first and second processing sections (14a,14b) that concurrently apply to the bus complementary portions of like information signals (e.g. longwords containing data). A fault detection element reads the resultant signal from the bus (20) and compares it with at least portions of the corresponding signals originally generated by the processing sections (14a, 14b) themselves. If there is discrepancy, the fault-detector signals a fault, e.g. causing the unit to be taken off-line. By use of a redundant unit, processing can continue for fault-tolerant operation.
