Title: Adaptive recourse allocation in a mobile telephone system
Inventor: ANDERSSON HANS E
IPC: H04B7/26
Filed: 1992-08-31
Abstract: Transmission quality of an ongoing call in a mobile radiotelephone system is monitored by measuring parameters indicative of transmission quality, evaluating transmission quality according to the measured parameters, repeatedly measuring the aforementioned parameters at intervals, and repeatedly evaluating transmission quality according to the measured parameters at a time interval variable according to the results of the previous evaluation. Effectively, the calls in progress are divided into different classes according to transmission quality with some classes requiring monitoring relatively frequently and other classes requiring monitoring relatively infrequently.      Alternatively, the waiting interval according to which a call is monitored may be determined on an individual cell-by-cell basis.

Abstract: A detachable carrier for mounting articles such as bicycles to a motor vehicle is disclosed.  The carrier disclosed includes a frame with laterally spaced side portions and a lower offset portion that rests on a surface of the carrying vehicle.  This surface is either a horizontal surface or a horizontal and vertical surface provided by the bumper either at the front or the rear of a motor vehicle.  The lower end portions of the offset portions form a fulcrum with the support surface of the vehicle about which the frame will turn in a lever action.  A lower pair of laterally spaced fastening straps with appropriate end fasteners secure a lower portion of the frame to the vehicle and an upper pair of laterally spaced fastening straps with appropriate end fasteners secure an upper part of the frame to the vehicle.  An article support on a pivotal hub assembly extends out from the sides of the frame in an extended position and is folded to a down position between the side portions of the frame when not in use.  A locking arrangement allows the support arms to be locked at any angular position and between the extended and retracted positions.

Title: Precodage de sequences de signatures pour systemes amdc
Inventor: WEERACKODY VIJITHA
IPC: H04W72/04
Filed: 1993-07-19
Abstract: L'invention est une méthode pour réduire le brouillage d'accès multiple dans les récepteurs de signaux (par exemple, les récepteurs de station de base) de systèmes de communication à accès multiple par différence de code en séquence directe (par exemple, les systèmes radio cellulaires). Cette méthode permet de précoder des séquences de signature d'utilisateur pour étaler les signaux d'information à émettre. L'utilisation de séquences de signature précodées réduit considérablement le niveau moyen du brouillage d'accès multiple dans les récepteurs. Le désétalement des signaux reçus par les récepteurs peut être effectué à l'aide des séquences des signatures originelles (c'est-à-dire les séquences non précodées). Il n'est donc pas nécessaire de modifier les récepteurs. La méthode de l'invention comporte un mécanisme qui permet de déterminer un ensemble de séquences pour un émetteur et un récepteur à partir d'un ensemble réduit de séquences orthogonales.

Title: Data compression usin multipel levels
Inventor: BUGAJSKI JOSEPH M
IPC: G06F17/30
Filed: 1992-05-11
Abstract: A series of data processors (20a-20n) operate on a body of data to convert it to compressed form for storage or transmission. The processors are connected in series such that the output of one processor is the input to the next processor. Each processor has an associated memory (24a-24n). Each processor analyzes the serially input data elements in pairs to detect previously non-occurring pairs and stores those pairs in its memory. The output signal from each processor identifies the storage position in its associated memory of each input pair, whether or not the pair previously occurred. Each processor provides a single storage location output signal for each input pair of elements and maintains a count of the occurrences of each pair.

Title: Vaporizer key-fill adaptor using indicator glass air access
Inventor: LAVIMODIERE MAURICE
IPC: A61M11/00
Filed: 1994-01-05
Abstract: An apparatus is disclosed for converting vaporizers such as the DragerTM model 19 from pour-fill to safer indexed key-fill. The problem of such conversion specific to this vaporizer, and others configured similarly, is that the only air hole provided on the front face is through the indicator glass. A special pin is fashioned to screw up into the indicator access hole existing on the fill apparatus on the vaporizer, and a hollow needle extending from this pin extends up through the indicator fluid and carries air from the indicator glass out to the refill bottle. Thus fluid can flow through the adaptor and pin and through existing channels in the vaporizer fill apparatus and into the vaporizer. and decompressing air can return through the hollow needle. A special breather hole and plug is also provided on the adaptor for escape of fluid that may on rare occasions be introduced into the needle.

Abstract: HIGH DENSITY, HIGH CAPACITY BATTERY ELECTRODE                Abstract of the  Invention There is now provided an improved manufacturing method for increasing the active material filling density in a small DTR reticulated nickel sheet.  The nickel sheet has desirable physical properties such as resistance to breakage and crushing, in repeated bending.  This resistance can be for both the surface area and the central area, in the thickness direction of the sheet.  Such small DTR sheet has not previously been preferred as a battery electrode material because of a smaller filling density using conventional methods. There is now provided a battery electrode having high filling density of active material, high utilization rate of the impregnated active material and high capacity density with long life.  Furthermore, a method of producing such small DTR of reticulated nickel sheet in a continuous and economical manner is disclosed.
