摘要:
The invention relates to a polyurethane obtainable by reacting a polyisocyanate and a polyol composition comprising a highly branched polysaccharide of randomly bonded glucopyranose units or an alkoxylated derivative of the same. The polysaccharide has an average number of 10–100 glucose residues and said polysaccharide and derivative both have an average functionality of 30 or more. The invention also relates to a process for the production of such a polyurethane as well as a mix for the production of a polyurethane comprising a polyol composition, comprising 2–100 % of a highly branched polysaccharide, at least one catalyst and at least one surfactant.

A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.

A method and apparatus for obtaining overhead information by a mobile is provided herein. During operation, the mobile will be communicating with a first system on an active data channel. The mobile node will be able to measure pilot PN phase and amplitude for a second system that is a potential candidate to handoff and will have that information available. The data channel of the active service is used to query a proxy server that provides overhead information for the second base station. More particularly, when PN phase and amplitude information is provided to the proxy server, the proxy server will identify the base station and provide the overhead information needed to associate with the second base station.

A robust single-chip hydrogen sensor and a method for fabricating such a sensor. By utilizing an interconnect metallization material that is the same or similar to the material used to sense hydrogen, or that is capable of withstanding an etchant used to pattern a hydrogen sensing portion, device yields are improved over prior techniques.

摘要:
A robust single-chip hydrogen sensor and a method for fabricating such a sensor. By adding an adhesion-promoting layer between the body of a sensor and an on-chip hydrogen-exposed electrically-resistive hydrogen-sensing element, device yields are improved when compared to directly applying the electrically-resistive hydrogen-sensing elements to the sensor body. The resistance of the sensing element is indicative of the hydrogen in the medium surrounding the sensor. According to a preferred embodiment of the present invention, the adhesion-promoting layer is a chromium (Cr) adhesion layer, and the hydrogen-exposed electrically resistive hydrogen sensing element is a PdNi alloy.
