Granted: 1998-07-14
Abstract: An optical demultiplexing system enables a wanted channel to be extracted as  an optical  signal  from an optical carrier modulated by a TDM data flow.  The system makes use of a semiconductor optical amplifier, whose gain is modulated by saturation effect.  The amplifier receives both the modulated optical carrier and one or more sampling optical carriers, with wavelengths different from that of the modulated carrier.  One or more optical filters extract from the amplifier output the sampling carrier or carriers modulated by the wanted data signal or signals.

Filed: 1994-12-14
Granted: 2001-04-10
Abstract: A process to stabilize, deodorize, recover energy, reduce pollution potential, and add value to organic waste such as animal manure is described. The process involves the anaerobic digestion of animal manure at low temperatures in intermittently fed sequencing batch reactors . The process of the present application offers several advantages over the prior art processes including (1) the process works very well at low temperatures and therefore does not require pre-heating of the animal manure; (2) the process does not require continuous or daily feeding nor does it require continuous mixing; (3) the process makes use of existing handling and storage equipment at the farm and requires minimal supervision and skill by the operator; (4) the process is very efficient in retaining the slow growing microorganisms in the system and (5) the system is not affected by high concentrations of volatile acids and ammonia or nitrogen. Consequently, the process is low cost and does not interfere with regular farm operations.

Title: Lithium secondary battery
Inventor: YOSHIMURA SEIJI
IPC: H01M10/36
Filed: 1995-03-07
Granted: 1998-06-30
Abstract: A lithium secondary battery comprises a negative electrode having lithium as an active material, a positive electrode comprising a boron-containing lithium-manganese composite oxide as an active material and a nonaqueous electrolyte comprising a solute and a solvent, the boron-containing lithium-manganese composite oxide having an atomic ratio between B and Mn (B/Mn) of 0.01 to 0.20 and an average valence of manganese before charge-discharge of at least 3.80, and the solvent being a mixed solvent containing 5 to 50% by volume of a butylene carbonate.

Title: Optical fiber gripping and positioning apparatus
Inventor: EVANS DAVID C
IPC: G02B6/46
Filed: 1995-05-15
Granted: 2003-09-16
Abstract: The apparatus uses a gripper mounted on a moveable arm to pick up an optical fiber at a pickup location, with the free end of the optical fiber extending from the gripper. The arm is moved to position the free end generally in the region of the target location, but slightly displaced therefrom. An image of the region of the target location is obtained from a camera directed to receive the image, where the region is backlit by diffused light from a light source. Where the target is a component on a translucent substrate, the substrate may act as the diffuser for the light source. The image from the camera is analyzed to determine the position ofthe free end in relation to the target location, and the arm is moved to accurately position the free end at the target location based on the determination of relative positions. The gripper has a downwardly-opening inverted V-shaped groove runninglongitudinally, to which a vacuum is supplied.

Abstract: A satellite receiver for digitally encoded television signals includes apparatus for generating a signal indicating the alignment of the receiving antenna which is responsive to the number of errors contained in the digitally encoded television signals. The antenna alignment signal has the form of an audio signal which is coupled to sound reproducing device associated with the satellite receiver. The audio signal corresponds to a continuous tone when the number of errors is less than a predetermined threshold indicating that error correction is possible. The elevation of the antenna is set according with the location of the receiving site. Thereafter, the azimuth of the antenna is coarsely aligned by first rotating the antenna in small increments so locate a region in which the continuous tone is produced. During this coarse alignment procedure, the tuner of the satellite receiver attempts to locate a tuning frequency at which and demodulation and error correction is possible. If no appropriate frequency is found after a range of frequencies have been searched, a tone burst or beep is produced. The beep prompts the user to rotate the antenna by another small increment. Once the continuous tone has been produced, a fine alignment procedure is initiated in which the antenna is rotated to locate boundaries of an azimuth arc through which the continuous tone is produced. Thereafter, the antenna is set so that it is approximately midway between the two boundaries of the arc.

Granted: 2000-12-12
Abstract: A progressive multifocal ophthalmic lens is provided comprising an aspherical surface having a mean sphere and a cylinder at every point.    The aspherical surface comprises a distance vision portion, with a control point for distance vision, a near vision portion with a control point for near vision, and an intermediate vision portion between the near vision portion and the distance vision portion.    A power addition value A is defined as a variation in mean sphere between the control point for distance vision and the control point for near vision portion.    A base B is defined as a value of mean sphere at the control point for distance vision.    A width of the near vision portion varies not only as a function of the power addition value A, but also as a function of the value B of the base.    The  invention  thereby  ensures  the  presence  of  a substantially constant object field for all values of the power addition and of the base.

Inventor: KATHMANN JOHN A
IPC: G08B13/24
Filed: 1996-03-11
Granted: 1997-11-18
Abstract: A combination of a preprinted pressure sensitive label and an electronic article security system target is provided, preferably as a supply of labels on a backing material web with the target between. The labels preferably extend about at least about 1/8th inch around the edge of the target to directly adhere to the products. Articles may be selectively marked with targets so concealed to deter theft with fewer targets. The combinations may be formed by applying first the target, then the label, to the article. Preferably, label and target combinations are supplied on a web and are then applied to the products. Combination label and target supplies may be formed by separating the preprinted labels from their backing material webs, applying the targets to either the label or the backing material, and then combining the label with either the same backing material web or a different one. With discrete cut labels on a backing web, pressure sensitive adhesive coated targets are applied to the web and pressure sensitive labels are applied over them. For high speed production, targets are applied to the adhesive side of an uncut label web that has been separated from its backing material, then relaminating the combination onto the same or a different backing material web. Discharges of electrostatic charge that could damage the target circuits are reduced by using rollers and peeling knives made of non-electrically conductive materials to contact the markers or targets and by using ionized gas to neutralize the charge.

Abstract: A solid-state detector for use in an atomic spectrometer comprises a plurality of arrays of sensing elements, or pixels, each of the arrays being positioned along and on the locations of spectral signals on a focal plane of an echelle grating spectrometer. The sensing elements are positioned along the many diffraction orders presented on a two-dimensional echelle grating focal plane so that at least one element is located at each and every resolution element regardless of global x-y coordinate positioning of the elements or with reference to each other. The result is a series of skewed lines of sensing elements, those lines being in the same shape as the series of diffraction order lines which comprise an echelle spectrum. The solid-state detector is particularly useful in an atomic spectrometer wherein an echelle grating is used to diffract incident radiation such that the various components of the radiation may be observed.
