IPC: H04B1/7077
Filed: 1998-09-18
Abstract: In the present invention, the slave base station (64) attains synchronization with the reference base station (62) through messages transmitted from and received by a mobile station (60) in the soft handoff region between the reference base station (62) and the slave base station (64). First, the round trip delay between the mobile station (60) and the reference base station (62) is measured by the reference base station (62).  Once the mobile station (60) acquires the signal from the slave base station (64), it measures and reports the difference between the amount of time it takes a signal to travel from the reference base station (62) to it and the amount of time it takes a signal to travel from the slave base station (64) to it. The last measurement necessary is a measurement by the slave base station (64) of the time difference between the time it received the reverse link signal from the mobile (60) and station the time it transmitted a signal to the mobile station. A series of computations described in detail herein are performed upon the measured time values to determine the time difference between the slave base station (64) and an adjustment of the slave base station (64) timing is performed in accordance therewith.

Inventor: ELLIOT STEVEN K
IPC: G06F13/00
Filed: 2000-04-19
Abstract: A method, apparatus, and article of manufacture for providing to a signature hash for checking versions of abstract data types. An identifier is constructed for the abstract data type that is substantially unique to the abstract data type, wherein the identifier comprises a concatenation of various attributes for the abstract data type. The constructed identifier is hashed to generate a signature hash value for the abstract data type, which is then stored both in the database and a class definition for the abstract data type. When the class definition is instantiated as a library function, it accesses the abstract data type from the database, and compares the signature hash value from the database and the signature hash value from the class definition in order to verify that the class definition is not outdated. The class definition is outdated when the abstract data type has been altered without the signature hash value being re- generated and re-stored in the database and the class definition.

Inventor: PORTER MICHAEL J
IPC: F28C3/16
Filed: 2000-06-06
Abstract: The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum with two chambers, a first chamber having a stucco inlet and a second chamber having a stucco outlet. The stucco cooler includes cooling coils that are located within the plenum and a fluidization pad positioned at the base of the plenum that introduces air into the cooler.  Agitators positioned through the fluidization pad help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the cooling coils. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.

Title: Precision deep input guide clip for document scanners and document scanners incorporating same
Inventor: GATTO JEAN-MARIE
IPC: H04N1/12
Filed: 2000-06-27
Abstract: A document-guiding device that clips onto the image sensor of a document scanner ensures that documents to be scanned are introduced into the scanner at an optimal angle and are applied to the transparent surface of the image sensor at an optimal pressure, thereby avoiding scratching and soiling the sensor glass surface. Moreover, the deep input guide clip includes a sharp edge that acts as a scrapper to remove or flatten protruding impurities to further reduce soiling the sensor transparent surface. The deep input guide clip has the added benefit of stopping parasitic ambient light and protecting the image sensor against hard falling objects thus avoiding breakage of the transparent surface. The deep input guide clip forms a compact enclosure that may also hold a set of document proximity sensors and associated control electronics for precisely detecting the leading edge of the document when it is introduced in the scanner, its width and its trailing edge.

Title: Method and device for the autonomous production, preparation and supply of breathing gas to divers at extreme depths
Inventor: TODOROV GUEORGUI
IPC: A62B31/00
Filed: 1998-04-03
Abstract: The invention relates to a fully closed circuit- pendulum- storage system wherein a given amount of a ready to breathe gas mixture made of various inert gases including hydrogen and oxygen is continuously conveyed between two highly pressurized gas containers. Initially, the required breathing gas leaves the pressurized gas container and reaches the circuit at a constant dosage according to the overdosing principle. The circuit consists of an inhalation bag, a diving helmet, an exhalation bag and a single or double pack CO2 absorption filter. At a depth of 0-100m a mixture of oxygen, nitrogen and helium is used as a breathing gas. At a depth of 100-700 m a given amount of hydrogen is mixed therewith according to the wishes of the diver, whereby the oxygen content should not exceed 3 vol. %. When the diver emerges from a depth of over 100m the hydrogen is removed from the breathing gas and from the circuit by means of palladium membrane diffusion or catalytic water conversion. The removal of hydrogen is controlled by hydrogen detectors. At this point only, the oxygen content can exceed 3 vol %.

Patent CA-2318074-A1 (CA)
Inventor: GAIL WILLIAM B
IPC: G01W1/00
Filed: 1998-01-16
Abstract: The traditional minimum antenna area limit for synthetic aperture radar (SAR  204), imposed by ambiguity considerations, is eliminated by using a transmitter format providing distinguishable sub-pulses (256). Signal formats which are feasible for implementing such sub-pulses include frequency-division (i.e., a distinct frequency band is used for each sub-pulse), and code-division (i.e., sub-pulses occupying the same frequency band are grouped in distinguishable combinations). The nominal pulse period is divided into N sub-pulses (252), and the sub-pulse group is transmitted with the nominal pulse repetition frequency (f) (256). The range ambiguities are determined by the repetition rate of the sub-pulse group (f) and the azimuth ambiguities are determined by the repetition rate of the sub-pulses (N f). The antenna is capable of sampling a Doppler bandwidth that is a factor of N times the traditional value and the antenna (22) area can be reduced by a factor N from the limiting value presently used in SAR antenna design. A reduction in antenna length by a factor of N, for example, can be obtained at the expense of a signal-to-noise decrease of N and an increase in signal bandwidth by the same factor. Alternatively, the same antenna length reduction of N and an increase in signal-to-noise by a factor N can be obtained using the original bandwidth if the resolution is degraded by N.
