Title: Adaptive frequency dependent compensation for telecommunication channels
Inventor: WESEL RICHARD D
IPC: H03H21/00
Filed: 1992-05-20
Granted: 1996-07-02
Abstract: The quality of speech being transmitted in a telecommunication channel is enhanced by adaptively compensating for frequency dependent attenuation in the telecommunication channel. The frequency dependent attenuation in the telecommunication channel is dynamically determined and, then, compensated for by adaptively selecting and inserting an appropriate frequency dependent gain function in the telecommunication channel.

Title: Synthetic resin composition and interior material coated with the same
Inventor: HORII MITSUMASA
IPC: D06M15/227
Filed: 1992-07-24
Granted: 2000-11-28
Abstract: A synthetic resin composition comprises an aqueous medium, a surfactant, and a resin and filler dispersed in the aqueous medium by the surfactant. The surfactant comprises a first high molecular weight compound having a weight-average molecular weight of at least 10000 and a second high molecular weight compound having a weight-average molecular weight of not less than 150 and less than 10000. In the synthetic resin composition, a solid material is well dispersed and the viscosity doesn't remarkably increase even if a solid content is increased. So, the increased amount of a non-volatile matter may be used and the storage stability improves.      Further, flame retardation, deodorization, heat resistance and light fastness also improve. In addition, an interior material coated with the synthetic resin composition is provided. In the interior material, the texture, flame retardation, deodorization and light fastness improve without the deterioration of workability.

Title: Radiotelephone message processing for low power operation
Inventor: AUCHTER THOMAS J
IPC: H04M1/73
Filed: 1992-03-13
Granted: 1996-04-23
Abstract: The process of the present invention first synchronizes to incoming messages from the base station. The first data word is received and stored in the radiotelephone. The error code in the data word is next checked to determine if errors ex-ist in the word. If there are errors, the word is corrected. This process is repeated on another data word and the second received word is compared with the first. If the words are not equal, the receiver remains on until at least two words are equal or the entire length of the message is received. If the words are equal, the word is processed by the radiotelephone and the receiver is turned off for the remaining portion of the message until the next synchronization word is to be received.

Granted: 1996-10-08
Abstract: A data distributing method and an apparatus employing such method are disclosed, wherein a memory group stores the cumulative value of weighted values indicating data processing load of each kind of data or work unit outputted from a coupling unit.  A control circuit recognizes the kind of data that is inputted to each of two input lines of the coupling units, judges whether or not there is a deviation in distribution of data or work units which are transferred from a first memory group to a second memory group on the basis of the cumulative value stored in the memory groups that correspond to the kinds of data recognized, and changes over connection patterns of switch in the coupling unit so that any deviation is corrected, thereby equally distributing the data processing load of data or work units to the second memory group.

Granted: 1998-12-15
Abstract: A method and apparatus are disclosed for wrapping a load conforming generally to a rectangular solid, such as a cotton bale.  Lengths of wrapping film from two rolls are welded to form a predraped wall of such film, into which the load is conveyed to cover its front face and its lateral faces, whereupon the welded lengths are welded again behind the bale and are severed from such rolls.  As the load is conveyed, a length of wrapping film from a third roll is wrapped in a spiral pattern so as to cover the upper, lower and lateral faces of the load.  Moreover, generally V-shaped perforations pointing toward the front face are formed in the lateral faces, by means of perforating mechanisms.  Each mechanism comprises a pivotal arm biased toward the load, a wheel rotatable on the arm and perforating cutters extending radially from the wheel, in two circumferential arrays.

Granted: 1998-11-24
Abstract: Apparatus for wrapping articles in film material includes   a   stationary   frame   supporting   a   vertically reciprocable frame which in turn supports a rotatable, ring member carrying a film carriage assembly by which film is wrapped around an article during rotation of the ring member. The ring is in the form of an outwardly open channel and is supported for rotation relative to the reciprocable frame by wheels  on the  latter which underlie  the  upper flange of the channel.  The web of the channel is captured between pairs of wheels mounted on the reciprocable frame, and a wheel of one of the pairs is driven to rotate the ring relative to the reciprocable frame.  The reciprocable frame is elevated and lowered relative to the stationary frame by a  chain  drive  arrangement,   and  the  stationary  and reciprocable frames have interengaging guide components at two diametrically opposed locations.

Granted: 2007-01-16
Abstract: The present invention relates to an electronic identification system comprising one or more transponders which store identification and other information in memory, and readers, which capture information from the transponders and write new information thereto, and in which communications between transponders and readers are accomplished using radio frequency signals. The present invention has attributes which make it particularly useful in automatic fare collection systems, where transponders, typically in the form of thin cards and used as pre-paid tickets, are carried by fare paying passengers to replace printed tickets and eliminate exchange of cash. Specifically the system achieves simultaneous identification of numerous transponders by one reader, permits a reader to selectively programme any of many transponders under its control, exhibits fast transaction speed to maximize passenger throughput, and achieves exceptional data storage integrity.

Abstract: Existing infrastructures such as DS1 or E1 are used at currently accepted rates to carry a third more information by using a hybrid encoding technique wherein a 4B3T encoding is done for the payload bits, while a 1B1T encoding technique is used for framing information. In this way, for example, a DS1 can be used at 1.54 Mbit per second to carry 2.058 Mbits of binary payload, while respecting the 8 kilobits of framing expected by DS1 hardware.  Similarly, for example, an E1 infrastructure can be used at the accepted 2.048 Mbit per second rate to carry 2.560 Mbits of binary payload plus 128 kilobits of binary framing/CRC without having to change the accepted E1 framing techniques.

Abstract: A strip conveyor and stacker receives cut elongated flexible strips from a strip former and by conveying and stacking the strips produces a stack of strips such as a cellular panel for a window covering. The conveyor receives the strips from the strip former and includes a foraminous conveyor belt which holds the strips on the surface thereof by suction. At the stacker, the strips are discharged from the conveyor belt by applying a burst of pressurized air, thereby ejecting the strips into a stacker magazine. As the strips are stacked, the magazine is indexed to increase its depth, or a cellular structure formed by the stacked strips is withdrawn from the body of the magazine. An auxiliary magazine may be used to form a preliminary stack of soft, flexible strips prior to stacking in the magazine. A strip defect sensor scans each strip and causes the ejection of defective strips from the apparatus.
