Abstract: A system including an adaptor and a syringe is used for facilitating hemostasis of a biopsy tract or other puncture wound by delivery of an absorbable sponge in a hydrated state into the wound. The adaptor includes a tapered lumen for hydrating and compressing the relatively large absorbable sponge for delivery through a relatively small cannula, such as a biopsy needle. The hydrated absorbable sponge is injected through the biopsy needle into the biopsy tract by fluid. Alternatively, the sponge may be delivered to the biopsy needle by injection of fluid and then delivered to the biopsy tract by a plunger or stylet. The implanted absorbable sponge facilitates hemostasis at the biopsy site or other puncture wound and minimizes the chance of internal bleeding. The absorbable sponge material is absorbed by the body over time.

Abstract: In order to make notches in partitions separating substantially aligned recesses issuing onto the surface of a structure (10), use is made of a machining head (26) having a cutting tool (28) and at least one rotary member (52) adjacent to said tool. The rotary member (52) is provided with protuberances (54) supported in recesses of a row of recesses adjacent to that which is being machined, during the displacement of the machining head (26). The latter is connected with slackness to a tool holder by a mechanism, a lateral and height positioning of the tool (28) being ensured during machining.

Abstract: A semiconductor processing robot is provided with a robot arm on which is mounted an integrated edge gripper having an orienting assembly and a detecting assembly. The orienting assembly operates to rotate a substrate such that a substrate reference marking, or indicium, is positioned at the detecting assembly. The detecting assembly detects the location of the reference indicium and thereby derives information about the relative orientation of the substrate in the integrated edge gripper.

Abstract: A method of synthesizing higher surface area vanadium oxides, having the chemical formula V.sub.2 O.sub.13+x, wherein 0.ltoreq.X.ltoreq.0.5, that are employed in fabricating cathode active materials for solid secondary electrochemical cells, is provided. The method includes forming dense NH.sub.4 VO.sub.3 pellets and heating the pellets to decompose the NH.sub.4 VO.sub.3 into V.sub.2 O.sub.5 and NH.sub.3, whereby the NH.sub.3 reduces the V.sub.2 O.sub.5 into vanadium oxides.

Abstract: A low-cost, moderate performance small computer system is provided by allowing a single sharable block of memory to be independently accessible as graphics or main store memory. Allocation of the memory selected programmably, eliminating the need to have the maximum memory size for each block simultaneously. Performance penalties are minimized by dynamically allocating the memory bandwidth on demand rather than through fixed time slices. Efficient L2 cache memory support is provided based on a system controller having an integrated L2 cache controller and a graphics controller that supports an integrated memory system. The memory connected to the graphics controller may be partitioned into two sections, one for graphics and one for system use. Additionally, the system controller may or may not have attached additional memory for system use. L2 cache support is provided for all system memory, regardless of the controller that it is connected to.

Abstract: A low-cost computer system which includes a single shared memory that can be independently accessible as graphics memory or main store system memory without performance degradation. Because the "appetite" for main system memory (unlike that of a display memory) is difficult to satisfy, the memory granularity problem can be addressed by programmably reallocating an unused portion of a display memory for system memory use. Reallocation of the unused display memory alleviates any need to oversize the display memory, yet realizes the cost effectiveness of using readily available memory sizes. Further, reallocation of the graphics memory avoids any need to separately consider both the system memory and the display memory in accommodating worst case operational requirements.

The laminate is fan-folded into a stack such that substantially the entire surface area of the opposite polarity electrode segments are in contact with the electrolyte layer and in ion exchange with the electrode layer. Current can collected from the discrete opposite polarity electrode segments by opposite polarity electrode current collector strips that electrically connect the opposite polarity electrode segments. A method for making an electrochemical cell stack is also disclosed.

Abstract: A process for depth migration of seismic wave information that has been derived from geological media that causes rapid lateral velocity variations in seismic waves. The process includes the step of decomposing wavefields recorded at the earth's surface using Gaussian beams as basic functions. Then, according to the process, the set of Gaussian beams is extrapolated downward into the earth to obtain the subsurface wavefield. Finally, the wavefield is processed to provide depth-migrated images of subsurface reflectors.

Abstract: A system for controlling a pulse-driven dc motor includes a pulsed grounding switch, an inductor connected between the pulsed grounding switch and the armature of the dc motor, and a tracking circuit connected across the inductor. The control system further includes a variable resistor that provides a series path through the inductor for dissipating generated armature current from the motor. In operation, the resistance provided by the variable resistor depends upon the counter emf generated by the motor and upon transient voltages induced across the inductor when the pulsed grounding switch is periodically opened and closed. More particularly, the variable resistor provides minimal resistance when the back emf of the motor is low and provides increasing resistance as the back emf of the motor increases.
