Abstract: A method and system that enables the changing of the gain in a closed loop (e.g., self-configuring) telecommunications system based on the age of the available measurements. A high gain is used when measured data are “fresh”, so as to obtain a good performance (e.g., a fast response) for the telecommunications system. The gain is then reduced when the age of the measurements increases. The decreased gain results in a slower system response, but this is a desirable result in order to preserve stability. The system and method may be applied, for example, in many mobile telecommunications systems (e.g., GSM, WCDMA, etc.). In one embodiment, the system and method of the present invention modify the closed loop gain in an adaptive fashion and use one or more fuzzy membership functions for specifying what is meant by “fresh” measurements.

Abstract: The invention relates to an improved apparatus for thermal management in a gas purification process. As known in the prior art, a gas purification apparatus includes a two-section unitary vessel, wherein the primary section includes an impure gas inlet and a heating assembly and the secondary section includes a cooling device and an outlet for purified gas. Within the primary and secondary sections of the vessels are gas sorbing materials such as getters for removing impurities from the gas to be purified. A feature of the present invention is the continuous, serpentine shape of the gas purification vessel which allows for a longer residence time of the gas and a more efficient purification process. Another feature of the invention is a Joule-Thomson cooling device which divides the primary section of the vessel from the secondary section. The Joule-Thomson cooling device cools the secondary section of the vessel and the gas contained within it.

Abstract: An improved imaging system and method for providing increased viewer control over the operating parameters of the imaging system is described.

Abstract: A reconnaissance sonde to be dropped and erected in an area for wirelessly transmitting data to a data processing apparatus.

Abstract: An uplink common physical channel (random access channel) frame structure with a separate preamble and data portion. The preamble is used by a base station to detect that a mobile station is attempting a random access request. The data portion of the channel includes user data, and pilot symbols that provide energy for channel estimation during reception of the data portion. A guard interval can be generated using a “filler” made up of dummy chips, predetermined symbols, and/or an unmodulated carrier, and inserted between the preamble and data portion of the frame, thus enabling a mobile station to maintain its power transmission and making it easier to implement such a guard interval in a WCDMA system.

Abstract: The present invention is a dual mode antenna. The antenna of the invention connects in an inverted-F feed when in a retracted position, and in a monopole feed in an extended position. The antenna mounts adjacent a relatively large ground plane, such as a grounding shell or EMI shield included in a laptop computer display, for example. A preferred antenna includes an elongate radiator mounted in a non-conductive housing to permit retraction and extension of the elongate radiator. The housing includes electrical contact points that form an inverted-F feed antenna connection to the elongate radiator when the elongate radiator is in a retracted position. The electrical contact points form a monopole feed antenna connection to the elongate radiator when the elongate radiator is in an extended position.

Furthermore, the present invention suggests a bristle insert as a replacement part for said brush.

Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.

Abstract: A tubular body or mandrel incorporated into a string of tubular pipe, on which first and second swab cups and a casing scraper are mounted, is run into a cased earth borehole to displace a first fluid in the borehole, usually a drilling fluid, with a second fluid, usually either a completion fluid or a workover fluid. In a first embodiment, reverse circulation, in which the second fluid is pumped into the borehole annulus above the swab cups, and in which the first fluid is thereby pumped back towards the earth's surface through the interior of the string of tubular pipe, causes displacement of the first fluid merely by lowering the string of pipe while pumping the second fluid into the borehole annulus. In a second embodiment, using normal circulation, the first fluid is pumped from the earth's surface downwardly through the interior of the string of tubular pipe into the borehole annulus between the pair of swab cups.

Abstract: A thermal expansion compensation support and method are used in a hot runner injection mold for maintaining liquid-tight relationships between parts that define a flow passageway. The support includes an annular housing having an annular recess that receives a spring, such as a Belleville washer, and a cover that overlies the annular recess in the housing. The housing and the cover are spring biased from each other to maintain a pressure force on the surfaces that are in contact with the outer faces of each of the cover and of the annular housing. The support imparts a holding force on the several parts of the machine that define the molding material flow passageway to prevent leakage. The method involves holding the parts together at a first holding force level for an initial portion of a warm-up temperature range and holding the parts together at a second holding force level for the remainder of the temperature range.
