Title: Pattern-recognition computing and method for producing same
Inventor: HAIT JOHN N
IPC: G06V10/88
Filed: 1995-12-14
Abstract: Pattern-recognition computing can be accomplished using wave-type or other types of energy. In pattern-recognition computing which uses a plurality of wave-type energy input patterns modulated with quantized information (10, 11, 12, 13), energy from the patterns combines to produce interference-based dynamic images (31, 31A). Component parts of a dynamic image are separated and recombined to produce logic and other computing process outputs (28, 29). To produce a coordinated set of optics for pattern-recognition computing, waveforms at pixel-sized image components of the dynamic image are chosen to become contributors to the combined output if they will contribute (or can be modified to contribute) in a positive manner to a combined output waveform that obeys the logic rules of the device being produced. Iterative changes in input pattern characteristics are used to optimize the coordinated optics. Pattern-recognition computing can also use special interference and frequencymultiplexed logic.

Title: Washing device for automatic biochemical analyzer
Inventor: SAITO SHIN
IPC: B01L99/00
Filed: 1997-08-13
Abstract: There is disclosed a washing device for use with an automatic biochemical analyzer using reaction containers.  The washing device comprises a sucking portion and a draining tube.  When the sucking portion is advanced into anyone reaction container placed in position and is set in a given position, a communication passage is created between the inner wall surface of the container and the outer wall surface of the sucking portion and between the bottom surface of the container and the bottom surface of the sucking portion.  During draining, the container is depleted of wash liquid.          Outside air flows from the communication passage into the container through its opening at the top end at a flow rate more than a given value.  The air flow blows away the water droplets adhering to the inner wall surface of the container.  The blown water droplets are urged downward toward the sucking port in the suction portion. Then, the water droplets are discharged into a waste tank through the draining tube.  Thus, the water droplets can be easily and almost completely removed.

Title: Use of polyurethane membrane for maldi-tofms analysis of whole blood
Inventor: O'NEIL JOE
IPC: H01J49/16
Filed: 1998-01-30
Abstract: The use of non-porous membranes as sample supports for MALDI-TOFMS analysis of peptides and proteins as well as for the analysis of whole blood is herein described. Non-porous membranes have a uniform surface, allowing for greater sensitivity and accuracy. Specifically, the non-porosity favours crystal growth on the surface of the membrane only, thereby providing enhanced spectral quality over membranes with porous structures. Studies were performed using polyurethane (PU) membranes as an example of non-porous MALDI sample supports which showed that PU membranes yielded higher quality spectra compared with porous membrane sample supports such as polyether and polyvinyl difluoride) and the spectra obtained from PU membranes are of comparable quality as those obtained with metallic targets. However, the sample preparation for use with PU  membranes is much less arduous compared with the preparation necessary for metallic targets.

Title: Target-tracking laser designator
Inventor: LIVINGSTON PETER M
IPC: G01S17/66
Filed: 1998-07-22
Abstract: The present invention provides a laser tracking system including a laser generator for generating a beam of laser energy, a beam steerer for steering the beam of laser energy such that it moves in a search pattern, and a receiving device that receives laser energy reflected from a targeted object and that causes the beam steerer to vary the search pattern in response to the reflected laser energy. A tracking method associated with the laser tracking system includes the steps of generating a beam of laser energy, steering the beam of laser energy in a search pattern, detecting a hit spot formed from laser energy being reflected from a targeted object, diminishing the size of the search pattern in response to the detection of the hit spot, and focusing the diminished search pattern on a feature of the targeted object corresponding to the hit spot. The laser tracking system and associated method presented provide a number of advantages over conventional tracking systems. The laser tracking system employs closed loop methodologies allowing the system to accurately track targeted objects using continuously updated tracking data. The laser tracking system is able to seek and lock on to vulnerable features of potential targets. Further, the laser tracking system is able to maintain a desired aim point indefinitely and without operator intervention. This aim point maintenance allows an associated weapon to disable a target, despite any relative tracker-target motion during the munitions launch and flight.

Title: Large round baler net wrapping device for dispensing net from a supply roll resting on driven feed roll
Inventor: LEIBER YUVAL
IPC: A01F15/07
Filed: 1998-09-03
Abstract: A large round baler is equipped with a wrapping device for wrapping a bale with a web of plastic net wrapping material. The device includes a pair of wrap material feed rolls arranged one above the other with a supply roll of wrapping material being directly supported by the upper feed roll so that during operation of the feed rolls in dispensing a length of wrap material being wrapped about a bale, the periphery of the supply roll is rotated at the same speed as the periphery of the upper feed roll so that no scrubbing takes place between the supply and feed rolls. A pressure applying device uses a pair of air or gas cylinders acting through a linkage to force a free rotating roller to exert a force on the supply roll which is transferred through the roll to the feed roll. In this way variable friction forces are avoided which would interfere with the maintenance of a desired constant tension in the length of wrapping material so that the bale is wrapped tightly, but without rupturing the net material.
