Title: Multichannel optical fiber communications
Inventor: GILES CLINTON RANDY
IPC: H04B10/17
Filed: 1996-02-05
Granted: 1999-09-21
Abstract: WDM optical fiber communications entails bidirectional transmission with at least two WDM channels in opposite transmission directions in a single fiber. As compared with unidirectional transmission, a number of capacity-limiting considerations are relaxed. Operation using in-ground dispersion-shifted fiber permits system capacities of conventional unidirectional WDM.

Title: Methods of preparing cutting tool substrate materials for deposition of a more adherent diamond coating and products resulting therefrom
Inventor: MARTIN SCOTT D
IPC: B23B27/14
Filed: 1996-12-13
Granted: 2000-02-08
Abstract: Methods for preparing a cutting tool substrate material for diamond coating include providing a grooved pattern on selected portions of at least the top surface and preferably also the sides of the substrate material. The pattern may be a cross-hatching, a diamond-hatching, or another design. The pattern is preferably applied to the tool substrate by scribing with a laser ablation tool. The pattern is designed to optimize adhesion of CVD diamond on the portions of the tool substrate which areexpected to be most challenged during a cutting process. The dimensions of the pattern (e.g. the depth and spacing of scribe lines) are selected to provide the optimum combination of mechanical bonding and diamond nucleation during the CVD coating of the tool substrate. According to preferred aspects of the invention, the pattern is applied only to the portions of the surface not immediately adjacent to the cutting edge of the tool substrate, thereby sparing the geometry of the cutting edge itself. According to a one embodiment of the invention, the pattern includes a cross hatch on the top surface and on the side surfaces of the substrate. According to a another embodiment, the top surface is cross hatched in the center while the corners of the top surface are provided with parallel grooves. In another embodiment, the side surfaces are provided with parallel grooves parallel to the top surface.

Abstract: A block decision feedback equalizer uses a Cholesky algorithm to factora channel impulse response correlation matrix in order to solve for data received over a dispersive communications channel. While the Cholesky algorithm increases the computational complexity of the initial data symbol estimate (the result of a linear block estimation), its use allows the use of a recursive update for computing successive data symbols with little additional computation. Further, the Cholesky algorithm is free of limitations that would limit detection to cases where the channel span or memory is smaller than the probe segment following the data block to be detected. Additional functions such as diversity combining, incorporation of a time-varying channel response model and fractional baud-period sampling are provided in the block detector.

Title: Automated washing system for shelled seafood
Inventor: MACDONALD WENDELL
IPC: A22C29/00
Filed: 1997-04-04
Granted: 1998-07-28
Abstract: A washing system for shelled seafood items comprises a frame having mounted thereon a conveyor belt apparatus adapted to transport the seafood, a nozzle apparatus for directing a high-pressure water spray towards a belt of the conveyor belt apparatus, and a spray shield for shielding from the water spray a portion of the belt on which a selected part of each seafood item is to be placed.  The washing system is suitable for shelled seafood having a fragile portion that would otherwise be destroyed by the high-pressure spray, such as crab sections.  When the crab sections are placed on the conveyor belt with their selected fragile portion under the spray shield, the fragile portion is protected from the water spray by the spray shield while the rest of the seafood is washed.

Located between the parallel side walls (4, 5) of the housing sections (2 , 3) is a switchgear with a contact bridge (13) , the movement of which is guided parallel to the side walls (4, 5). Essentially, it extends in longitudinal direction at a right angle to the side walls (4, 5) and while in the on position between two fixed contacts (14, 15) that are fastened inside the housing and are positioned on both sides of the movement plane for the switchgear. The fixed contacts (14, 15) are flat pieces akin to a knife blade. They fit against the side walls (4, 5) and respectively form a contact point (16, 17) with their narrow, knife-blade type edges facing the contact bridge (13). With their rear sides (18, 19) opposite the contact points (16, 17), the fixed contacts (14, 15) fit against a flank wall (12) of housing (1). As a result of this, the fixed contacts (14, 15) are positioned especially space-saving in the corners of housing (1).

Abstract: The system images the volume of a turbid medium and detects the contents. The medium can be water or air, or living tissue, or almost any other material which is at least partially light-transmissive. The system includes a light source for producing a series of discrete fan-shaped pulse beams that are substantially uniform in intensity or have been peaked at the edges of the fan to illuminate sections of the medium, a streak tube with a large, thin-slit-shaped photocathode for collecting the maximum amount of light from weak returns, a field-limiting slit disposed in front of the cathode for removing multiply scattered light, a large-aperture optical element for collecting and focusing the reflected portions of the pulse beam on the field-limiting slit and the cathode, and an array of detectors. A volume display of the medium is generated by translating the transmitter and receiver normal to the longitudinal axis of the pulse beam, to illuminate adjacent sections of the medium, and combining the sections to provide a volume display. All, or substantially all, of the light returned from each pulse beam is used. Vehicle motion can be used to provide the scan of the beam.  Applications range from foggy sky surveillance at multiple-kilometer scale to location of fractional-millimeter tumors in a human breast.

Abstract: The present invention relates to razor blade cutting edges which exhibit an improvement in the first shave. Conventional razor blade cutting edges exhibit surprisingly high initial cutting forces. Razor blades produced according to the present process exhibit significantly lower initial cutting forces which correlates with a more comfortable first shave. Improved blades according to the present invention involve treating conventional razor blade cutting edges having an adherent polyfluorocarbon coating with a solvent to partially remove some of the coating. Preferred solvents include perfluoroalkanes, petfluorocycloalkanes, perfluoropolyethers having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent. The present invention also relates to the method of producing these razor blade cutting edges.
