Title: Carrier recovery for digitally phase modulated signals, using a known sequence
Inventor: CHLOMA ALEXANDRE
IPC: H04L7/00
Filed: 1996-06-26
Granted: 2001-02-06
Abstract: A method of carrier recovery in a wireless communications system using a known synchronization word, for example an IS-54 TDMA system, operates in two stages to produce an estimate of carrier phase. In the first stage, a complex fading factor, embodying carrier phase information, is estimated from the synchronization word in the received signal using at least square criterion. In the second stage, the carrier phase is estimated from this complex fading factor by averaging. The averaging can provide a recursive average or a moving average, or can be implemented using Kalman filtering which also provides an estimated amplitude factor and frequency shift. The method and apparatus provide a substantial improvement over phase locked loop carrier recovery.

Inventor: WENDELIN GEORG
IPC: B29C48/03
Filed: 1996-12-02
Granted: 2002-02-19
Abstract: A device for filtering plasticised thermoplastics has a housing (1) with at least one supply channel (6) for the material to be filtered, via which said material is taken to the inlet side of at least one filter unit (3). The filtrate passes through fine holes (7) in the filter unit (3) and passes from its discharge side into at least one outlet channel (9) leading out of the housing (1). The inlet side of the filter element is scraped by the edges of doctor blades (11) moved in relation to said filter element (3), which guides the residues along the surface of the filter element (3) to at least one discharge channel (12). In the residue discharge direction the region (20) provided with holes (7) of the filter element adjoins an unperforated region (21) which is also scraped by the doctor blades (11). In the surface of the unperforated region (21) facing the doctor blades (11) there are grooves (29), the direction of which crosses that of the edges (24) of the doctor blades (11) extending over said grooves (29). The thickened compound on the unperforated region (21) is thus taken in concentrated form to the discharge channel (12).

Title: Self-collimating multiwavelength lasers
Inventor: XU JINGMING
IPC: H01S3/083
Filed: 1999-04-16
Granted: 2004-03-16
Abstract: The present invention provides self-collimating multiwavelength lasers (MWL) including a planar gain medium with a resonance cavity defined by superimposed gratings. These laser devices are characterized by lasing wavelengths with multiple peaks in their reflectance spectra defined by the superimposed gratings. The gratings also limit beam divergence, producing self-collimated multiwavelength output, with the potential for high power.  These devices can be implemented in any planar gain medium in which multi-peak gratings can be produced, including but not limited to semiconductors and doped glasses. The self-collimated MWL's disclosed herein have applications in areas such as DWDM (dense wavelength division multiplexing) communications systems, free-space uses such as interconnects, range-finding, and inter-satellite infrared communication. In one aspect the device is a multiwavelength ring cavity laser including a planar gain medium with two orthogonal pairs of supergratings (SG)A and B, which emulate the superposition of M and N single-pitch gratings respectively. SG-A has a set of M diffraction wavelengths that depends on the incident angle .theta.; a similar dependence on .PHI. = .theta.-90° exists for the set of N diffraction wavelengths of SG-B.  Wavelength-angle pairs common to both SG-A and SG-B will be resonant within the cavity as a whole. When combined with optical gain, the result is lasing at M by N wavelengths, collimated at a well-defined output angle.

Title: Hydrogen manufacturing and supplying apparatus and electric vehicle
Inventor: OGINO SHIGERU
IPC: B60L11/18
Filed: 1997-11-06
Granted: 2004-01-13
Abstract: The present invention provides an electric vehicle with fuel cells, which use hydrogen as a gaseous fuel, mounted thereon, a hydrogen generator supplier that feeds a supply of hydrogen to the electric vehicle, and a method of producing and feeding hydrogen. In the case where the supply of hydrogen is used as the gaseous fuel in the electric vehicle, there is difficulties in safely and widely distributing hydrogen to ensure the availability of hydrogen. The hydrogen generator supplier of the present invention utilizes, for example, the city gas, which is supplied to each house as a commercial gas, for a crude fuel and produces hydrogen from the crude fuel, in order to ensure the availability of hydrogen. The hydrogen generator supplier of the present invention is connected with piping of the commercial gas, and a supply of the commercial gas is fed as the crude fuel to the hydrogen generator supplier. The hydrogen generator supplier reforms the crude fuel to produce a hydrogen rich gas and subsequently separates gaseous fuel from the hydrogen rich gas. Connecting the hydrogen generator supplier with the electric vehicle via a specific connector enables the gaseous hydrogen, which is produced from the commercial gas used as the crude fuel, to be supplied to the electric vehicle. The hydrogen generator supplier of the present invention enables the supply of hydrogen to be used as the gaseous fuel in the electric vehicle, without founding a new distribution system of hydrogen.

Title: Double blank detector apparatus and method of operation
Inventor: BEZKOROW ANDREW J
IPC: B21D43/02
Filed: 1999-09-14
Granted: 2004-01-06
Abstract: A double blank detector apparatus and method of operation determines the condition of when one blank, no blanks or more than two blanks are about to be fed into a press. An indicator bar advances relative to the number of blank sheets of material being detected and interrupts an infra-red light beam when only blank of material has been detected. Under this preferred condition, a signal is produced which allows a press located adjacent to the double blank detector to continue its stamping operation. Alternatively, if either a no blank or a double blank condition is sensed, then the indicator bar advances accordingly, thus not interrupting the infra-red light beam. During this condition, a signal is produced indicative of the situation thus notifying the operator that there is a problem and stopping the press from cycling.

Title: Auxiliary corrective eyeglasses for use with primary eyeglasses
Inventor: LEDBETTER DONALD L
IPC: G02C9/00
Filed: 2000-06-16
Granted: 2005-03-01
Abstract: Auxiliary "task-distance" eyeglasses for use with conventional corrective eyeglasses to eliminate the constant head tilting otherwise necessary to maintain focus when using only the conventional lenses. The auxiliary glasses have upper partial lenses that correct mid-range vision, the focal length required for viewing a computer screen, reading piano music, viewing an instrument panel, or any other arms' length task. The zone of mid-range correction extends across the full width of the lenses. The lenses of the auxiliary glasses are connected by a bridge and supported on the primary glasses by two short tabs that extend sidewardly so as to rest on the temple members of the primary glasses. No clips or clamps are involved, so the auxiliary glasses simply "drop in" behind the regular glasses, avoiding damage to either the primary or the auxiliary lenses. This configuration makes the auxiliary glasses less obtrusive than conventional clip-on lenses. Moreover, the auxiliary glasses can be formed inexpensively in one piece of molded plastic, and can be sold without a prescription.

Abstract: A surface of a glass plate is coated with a first n-type semiconductor film which is a 50 nm-thick niobium oxide film as a primer layer. The primer layer is coated with a 250 nm-thick photocatalyst film comprising titanium oxide. Thus, an article having a photocatalytically active surface is obtained. The two coating films can be formed by sputtering.  The first n-type semiconductor film as the primer layer is selected so as to have a larger energy band gap than the titanium oxide. Due to this constitution, more holes are generated near the film surface. This article can be free from the problem of conventional titanium oxide films having photocatalytic activity that it is difficult to generate many surface holes contributing to photocatalytic activity, because electrons and holes generated by charge separation recombine within the film, making it impossible to effectively heighten catalytic activity.

Abstract: A cutting device is disclosed for use to derind a half-section of a citrus fruit. The device has an upwardly opened container with a vertical axis.   An upwardly opened cup is coaxially mounted in a removable manner within the container at a short distance from the upper edge thereof, in order to receive and hold he half-section to be derinded. A manually operable knife-supporting element is removably mounted in a rotatable manner coaxially on top of the container. This element has an annular bottom edge shaped and sized to fit and be slidable onto the upper edge of the container. It also has a knife-receiving sleeve that extends at a radial distance from said vertical axis and projects downwardly towards the central bottom portion of the cup. A knife is removably insertable into the sleeve after the half section has been positioned on top of the container. Once inserted into the sleeve, the knife has its blade that penetrates into the fruit at a short distance from he rind thereof and allows the half-section of the fruit to be derinded upon manual rotation of the knife-supporting element with respect to the container. Advantageously, the device may have two or more cups having central portions of different sizes to receive fruits of corresponding different sizes. In such a case, the knife-supporting element also has a corresponding number of knife receiving sleeves located at different radial distances to allow optimum adjustment of the position of the blade of the knife depending on the size of the central portion of the selected cup.
