Patent EP-0818737-A2 (EP)
Inventor: MOU ALEX ZHI-JIAN
IPC: G06F17/17
Filed: 1997-07-01
Abstract: Symmetry in a filter is used to reduce the complexity of an interpolator or a decimator and
to simplify derivation of resulting discrete samples. In particular, a weight filter matrix which
includes L=(N-1)M+K weights is divided into two sub-filters, the first having L1=NK weights and
the second having L2=(N-1)(M-K). In the case of interpolators, N source samples are applied to
the first weight sub-filter to produce K interpolated signals and N-1 source samples are applied to
the second weight sub-filter to produce M-K interpolated signals. In the case of decimators, K
source samples are applied to the first weight sub-filter to produce N decimated sample
components and M-K source samples are applied to the second weight sub-filter to produce N-1
decimated sample components. If the weight filter matrix is centrosymmetric, both sub-filters are
also centrosymmetric. Symmetry in the weights of each sub-filter is recognized and exploited.
Within each sub-filter, an inverse relationship between weights applied to two samples is
recognized and exploited. An inverse relationship is recognized when a first weight is associated
with a first of the samples and a second weight is associated with a second of the samples and a
weight which is equivalent to the first weight is associated with the second sample and a weight
which is equivalent to the second weight is associated with the first sample. The inverse
relationship is exploited by forming two composite weights of the first and second weights and
weighting composite sample signals with the composite weights. A first of the composite weights
has a value which is one-half of the sum of the values of the first and second weights. A second
of the composite weights has a value which is one-half of the difference of the values of the first
and second weights. The composite weights can be used repeatedly for each subsequent
interpolation or decimation and are therefore calculated only once for processing many samples
according to the same filter. The two composite samples have values which are, respectively, (i)
the sum of the values of the first and second samples and (ii) the difference of the values of the
first and second samples.

Abstract: A record head for an electrostatic ink jet recorder of the present invention is formed with undulation having a high aspect ratio thereon. Channels formed between nearby ridges due to the undulation are used as ink passageways. This allows the ridges to form convex ink meniscuses stably at all times at their front ends or ejection points, and thereby insures stable ejection of ink drops. Moreover, ink fed to the front ends of the ridges is constantly circulated by way of an ink collecting member. The circulation of the ink maintains the toner content of the ink uniform throughout the ejection points, and prevents the toner particles from excessively concentrating on the ejection points where ink ejection does not occur.

Abstract: A linear stapler particularly adapted for open surgical procedures is disclosed. Staples are fired when tissue is clamped between the cartridge and anvil of the staple fastening assembly of the stapler, and the firing trigger is pivotally rotated in a counterclockwise direction from an unfired position to a fired position adjacent the hand grip of the frame of the stapler. Resistance to the pivotal rotation of the firing trigger independent of the staple fastening assembly is provided to inhibit the surgeon from inadvertently firing the staples or partially firing the staples from the cartridge against the anvil. The firing bar is sandwiched between two spacer plates secured to the firing bar, and a stationary slot pin must overcome the resistance of detents displayed on slots in the spacer plates when the firing bar is moved distally to fire the staples. An audible signal is also provided to alert the surgeon when staples have been fully fired. One of the spacer plates has a signal spring and pin which interacts with a signal ramp attached within the frame. As staples are being fired, the ramp deflects the pin, and when firing is complete, the spring disengages from the ramp and impacts the inside of the frame to provide an audible signal. Although the invention is described in connection with an open linear stapler, it is broadly applicable to other surgical fastening instruments, including endoscopic linear staplers.

Abstract: A filler material guide nozzle assembly (12A) for feeding fusible filler metal wire (10) or other metal forms into reduced-width, high-aspect-ratio (ratio of depth to width) metallic joints (2) with control and stability of the filler metal position as it enters the molten pool area. The filler material guide nozzle assembly is designed with a thin but stiff non-circular cross-sectional shape, with its width dimension significantly greater than its thickness dimension, and can be utilized in very reduced-width welded or otherwise fused joints to provide the accuracy and stability required for reliable filler material addition. During use with welding, brazing and similar processes, the outlet end of the nozzle is located within the joint near the bottom, close to the area (4) to be fused. The width dimension of the nozzle apparatus is oriented parallel to the depth of the weld joint, and the thickness dimension is oriented perpendicular to the depth of the joint. The thickness of the nozzle apparatus is less than the thickness of the joint between the components to be fused with the filler metal, allowing the outlet end of the nozzle to be fitted within the joint and in closer proximity to the molten pool during the joining process.

Abstract: Within a vacuum vessel 10, there are arranged an electron gun 2
emitting an electron beam and an amplification part 3 which amplifies incident
light 7 by means of the energy of the electron beam. The amplification part 3
is formed by two wave-like mirrors 4 and 5 made of a metal such as Ag or
multi-layer structure of dielectric materials, said mirrors being separated from
each other to constitute not only an electron beam travelling part, but also a
light input part 4a, 5a, a light amplifying part 4b, 5b and a light output part 4c,
5c arranged in this order viewed in a travelling direction of the electron beam.
The light is made incident upon the light input part at a given incident angle,
and propagates along the wave-like or zigzag optical waveguide within the
light amplifying part by repeating reflections. Therefore, the wavenumber of
the light is increased and the light is amplified in a unidirectional manner by
the energy of the electron beam. The thus amplified light emanate from the
light output part at a given exit angle.

distortions can occur, and utilizes a highly robust method for recognizing the
characters of an ID. Multiple character recovery schemes are applied to account
for a variety of conditions to ensure high accuracy in identifying the ID. Accuracy
is greatly enhanced by taking a comprehensive approach where multiple criteria
are taken into consideration before any conclusions are drawn. Special
considerations are given to recognizing the ID as a whole and not just the
individual characters.
