Abstract: A surgical instrument including a system for stopping a beam of the surgical instrument from impacting a distal pin when reversing a knife is disclosed. A knife assembly of the surgical instrument comprises the knife, the beam, and a firing nut. A firing lead screw can drive the firing nut distally and proximally. A firing screw compression spring extends along the firing lead screw and applies a load proximally on the firing nut when the firing nut is driven toward a distal end of the firing lead screw.

Abstract: A system for preventing unwanted tissue migration in surgical staplers includes a surgical stapler having an end effector including an upper jaw and a lower jaw. A distal end of the upper jaw is connected to a distal end of the lower jaw, and a proximal end of the upper jaw is connected to a proximal end of the lower jaw. First and second tissue stops are formed on the distal and proximal ends of the lower jaw, respectively. The second tissue stop and the proximal end of the upper jaw define a no cut zone when the surgical stapler is in an open position. The surgical stapler also includes a tissue cutting device disposed within the lower jaw for resecting tissue. The system also includes a warning, blocking, impeding, or barrier forming device for preventing the unwanted migration of tissue into the no tissue zone.

Abstract: A wall support and reinforcing apparatus that applies a constant force on a structural support member, such as a steel I-beam, that is adjacent the wall. The apparatus includes a bias that is interposed between the building, or a bracket mounted to the building, and the structural member. Thus, the bias force is applied to straighten the wall at all times, thereby having the straightening effect and keeping the structural member from being displaced laterally due to complete release of all forces to the structural member.

Abstract: A method and apparatus for the control of darkness/lightness in a digital image rendered by a printing system. The technique preferably employs templates to selectively apply different amounts of darkening (lightening) to borders of structures detected within the image dependent upon the need for darkening (lightening).

Abstract: A system for providing an output from a digital printing apparatus which is of higher resolution than the native resolution of the original image data. For a given center pixel area, image data corresponding to pixel areas generally neighboring the center pixel area are attempted to be matched to various templates which are consistent with curved lines in which resolution enhancement of the center pixel would be desirable. In a second stage of template matching, a second set of image data, corresponding to pixel areas further away from the center pixel than the first set of pixel areas, is also attempted to be matched to templates. The second stage of template matching helps to avoid resolution enhancement of image data which is related to a halftone image.

Abstract: A lead edge lightening circuit which will lighten a scan line based on a seven by seven pixel area surrounding the current pixel. The area is divided into four sub-areas, each of four by four pixels, and each having the current pixel at one corner. Each sub-area is summed and compared to a threshold number. If the threshold number is equalled or exceeded by at least one of the four sums, an overlay bit, which can be white or black, is output. The current pixel is replaced by a white pixel if a white pixel has been output, otherwise the current pixel remains unchanged.

Abstract: A device attachable to at least one of the co-acting jaws of a steel jawed trap for capturing an animal. The device has at least one cushion assembly that includes an elongated carrier frame attachable to at least one jaw of the trap, and spaced apart cushion members secured to the carrier frame. The cushion members project outwardly from the carrier frame and are in a parallel alignment to one another to engage a limb of the animal and cushion and distribute the force of the jaws of the trap to reduce animal injuries.

Abstract: An animal pelt stretching and drying device that is adjustable for use with differently sized animal pelts includes a pair of spaced apart elongated side members and an inverted "V"-shaped top member that is adjustably attached to the side members to vary the distance the top member extends above the side members. Also, at least one cross arm member is associated with the side members for controlling the spacing therebetween and can also be adjusted to vary the position of the cross arm member with respect to the upper portions of the side members.

Abstract: An improved and unique mixing technique particularly useful as part of the process for the clinical analysis of liquid biological samples is described. The sample is placed in a cuvette along with a reagent and a diluent. The top (opening) of the cuvette is squeezed (reduced in size) and an air jet is directed against the liquid surface formed in the cuvette adjacent the junction of the liquid surface with the wall of the cuvette to create a vortex to produce thorough mixing of the contents of the cuvette and substantially prevent any splashing of the liquid contents.

Abstract: A single-chip microcomputer comprises a CPU (1), a RAM (2), an EPROM (3), a timer (4), serial I/O communication logic (5), four I/O ports (11-14) and an input pin for providing a RESET signal or programming potential V.sub.PP (23). An EPROM control register (53) in the CPU is loadable under the control of a computer program stored in an external memory (40). Responsive to a first bit in the EPROM control register an address buffer/latch 61 and a data latch 62 temporarily latch address and data information during a write operation to the EPROM. Responsive to a second bit in the EPROM control register the programming potential is applied to the EPROM for a predetermined time to program the data information into the EPROM at its associated address. The accuracy of the programming operation may be verified using the CPU under the control of the external computer program, to compare the address and data information programmed into the EPROM with the original source of such information.

Abstract: A microcomputer has the capacity for executing instructions, requesting prefetches of instructions, and experiencing a change in instruction flow, or a branch. The microcomputer also knows in advance that a change in instruction flow is going to occur. At such time that a branch becomes known there may also be a pending instruction prefetch request. Because a branch is going to occur, there is no need to execute the prefetch. Consequently, the pending instruction prefetch is flushed which thus avoids wasting time making an unnecessary instruction prefetch.

Abstract: In a data processor adapted to perform operations upon operands of a given size, a bus controller is provided to communicate the operands with a storage device having a data port which may be a submultiple of the operand size. In response to a signal from the bus controller requesting the transfer of an operand of a particular size, the storage device provides a size signal indicating the size of the data port available to accommodate the requested transfer. Depending upon the size of the operand to be transferred and the size of the data port of the storage device, the bus controller may break the operand transfer cycle into several bus cycles in order to completely transfer the operand. In the process, the bus controller compensates for any address misalignment between the operand and the data port.

Abstract: In a microcoded data processor, an instruction is provided which enables the microaddress for the micromachine to be externally specified. By way of this instruction, the processor may be directed to execute special microcoded routines otherwise unavailable during normal execution. These special microcoded routines may perform useful functions such as testing in an expeditious manner portions of the circuitry of the processor which would otherwise be difficult to test. For example, the functionality of regular structures such as instruction decoding and control programmable logic arrays (PLA's) may either be gated directly out to the tester or internally analyzed before the accumulated results are presented to the tester. On-board instruction caches may also be efficiently exercised to verify that the tag portion properly determines "hits" and "misses", and that the actual instruction cache portion functions accurately.
