Abstract: Several  different  types of electrical  switches  are disclosed.   In one particular embodiment,  an electrical switch is disclosed comprising: a molded case having a pair of conductive terminal contacts; and a molded actuator for mating with the case.   The actuator is movable between a conducting position and a non-conducting position within the case, and the actuator has at least one spring member and a conductive contact surface.   The spring member forces the actuator into the non-conducting position, and the conductive contact surface provides an electrical connection between the pair of conductive terminal contacts when the actuator is in the conducting position.  The actuator is retained within the case by a retaining member and/or a snap member.  The case and the actuator are molded about the conductive terminal contacts and the spring members, respectively.  Furthermore, the conductive contact surface is formed of a conductive elastomer  that  is  grafted  to  the  actuator.    In  other embodiments, the spring members are molded as a part of the actuator or the case, or the spring members are connected to the conductive contact surface or the conductive terminal contacts  with  the  actuator  and  the  case  being  molded thereabout, respectively.

Title: Multi-beam antenna arrays for base stations in which the channel follows the mobile unit
Inventor: CHANG CHU RUI
IPC: H04W16/28
Filed: 1996-11-25
Granted: 2003-01-28
Abstract: Cells in a radio telephone scheme are covered by beam-spots generated by multi-beam antenna system. Forward communication channels follow mobile units as they move between beam-spots. Additionally, each cell is divided into zones based on the mobile traffic patterns within the cell. Typically, there will be a high density zone covered by many, small area beam-spots, a medium density zone covered by two or three medium sized beam-spots, and a low density zone covered by one large beam-spot. As the mobile traffic patterns change throughout the day, multi-beam antenna dynamically reconfigures the zone and beam-spot layout for each cell, thereby keeping a nearly optimal zone and beam-spot configuration despite varying mobile traffic patterns.

Abstract: A device to aid in the subcutaneous injection of a hypodermic needle has an outer component which is a hollow longitudinal cylindrical sleeve with an inverted frusto-conical base capable of placement on a skin surface, and an inner component which is a hollow cylindrical sleeve of smaller diameter than the outer component and slidably disposed within the outer component. The inner component can hold various size adaptors to customize the device for use with different types or sizes of syringe. Located at the distal end of the inner component is a retaining collar with an aperture sized to receive the hub of a hypodermic needle and through which the needle projects. In a retracted position, the retaining collar rests inside a retaining groove circumscribed within the inner wall of the outer component.      The two components slide along a common longitudinal axis in a telescopic arrangement and their movement relative to one another may be controlled by spring means which is compressed when a manual axial force is applied to the syringe prior to insertion of the hypodermic needle. After fluid medication has been delivered at the targeted injection site and the axial force to the syringe is released, the inner component returns to its retracted position with simultaneous extraction of the needle driven by the force of expansion of the spring means. In particular, the device will assist those individuals who have difficulty in self-administering medication by means of injection as a consequence of visual impairment or poor manual dexterity.

Abstract: A system and method in a radio telecommunications network for correlating speech quality over an air interface link with a plurality of radio quality parameters. The system includes a mobile switching center (MSC) (13) for recording uplink radio quality information from the air interface link, a mobile test tool (12) for recording downlink radio quality information from the air interface link, a parser (16) for parsing the radio quality information into the plurality of radio quality parameters, and a memory (17) for storing the parsed radio quality information. A digital audio tape (DAT) recorder (19) or personal computer (PC) is electronically connected to a mobile station for recording a speech conversation from the air interface link simultaneously with the recording of the radio quality information. A DAT-link interface (21) is utilized to interface the DAT recorder with a playback unit(26)and with a synchronizer/controller (22) which synchronizes the stored radio quality information and the stored speech conversation. The radio quality parameters are presented to the operator in graphical form on a visual display (51) while the speech conversation is simultaneously presented to the operator in audio form (25). The operator enters a subjective evaluation of the speech quality of the speech conversation, and the evaluation is correlated with the radio quality parameters and displayed on the visual display.

Abstract: La présente invention concerne des particules fluorescentes capables d'émettre une forte fluorescence lorsqu'elles sont exposées à des rayons ultraviolets. Ces particules comprennent des granules préparées en broyant un mélange contenant un colorant fluorescent et/ou un pigment insolubles dans l'eau capables d'émettre une fluorescence lorsqu'ils sont exposés à des rayons ultraviolets, et une substance poudreuse contenant de l'amidon, de la cellulose, un polysaccharide, un saccharide et un analogue, ou contenant des granules qui renferme la substance poudreuse, une couche de protection à base de colorant fluorescent et/ou de pigment étant formée à la surface des granules. En outre, cette invention concerne un procédé de préparation de ces particules. L'association de résine présentant un groupe qui réagit avec le groupe hydroxyle de la substance poudreuse comme un liant permet de préparer des particules d'excellente résistance à l'eau. Par ailleurs, on peut préparer ces particules résistant à l'eau par un procédé consistant à incorporer le liant anionique dans les granules et à incorporer également une substance cationique dans la couche de protection, ou, à incorporer un liant cationique dans les granules et une substance anionique dans la couche cationique, grâce à l'interaction des ingrédients anioniques et cationiques incorporés. En l'occurrence, on peut utiliser ces particules fluorescentes pour préparer le papier anti-falsification contenant des particules qui émettent une fluorescence dans une nuance spécifique, et deviennent très visibles lorsqu'elles sont exposées à des rayons ultraviolets.

Abstract: Speech recording is effected in a GSM phone handset (100) by storing in a memory (116) speech frames during the presence of speech, one or more SID  frames during the absence of speech, and data representative of the duration of the absence of speech. In this way memory (116) does not store silent speech frames, and utilisation of memory space is therefore particularly efficient. In addition, items such as a voice activity detector and a comfort noise estimator, which are already provided in the handset as part of the GSM system, are "re-used" by the invention, thereby making efficient use of already-provided hardware/software.

Abstract: A method for producing hydrocarbons from a subterranean formation comprises injecting steam and an additive into the formation. The additive has at least one nonaqueous fluid, which is selected so that the evaporation temperature of the additive is within about ~150°C of the steam temperature at the operating pressure. Suitable additives include C1 to C25 hydrocarbons and combinations thereof. At least a portion of the additive condenses in the formation. The mobility of the hydrocarbons is greater than that obtained using steam alone under substantially similar formation conditions.
