Abstract: A digital radio communication system has a mobile station and a base station, the mobile station transmitting messages to the base station in a series of frames. Each frame has a header with a frame number and an optional polling indicator. A method of determining whether the base station is capable of receiving a message in automatic retransmission request (ARQ) format is provided. The method includes the step of transmitting from the mobile station to the base station a single frame in ARQ format with a polling indicator set such that the base station is prompted to send a status frame in ARQ format if the base station is capable of receiving messages in ARQ format. The method also has the step of determining if a status frame in ARQ format is sent from the base station to the mobile station in response to the single frame. A mobile station operating according to the method of the present invention is also provided.

Abstract: A compartmentalized trash can for sorting and storing different kinds of recyclables. A plurality of partitions are disposed in, and divide, a container into a plurality of sub-chambers. A lid is hingedly attached to, and selectively opens and closes the container. An apparatus opens the lid by use of a foot of a user. A liner bag removably lines the container and is defined by a peripheral flange, and includes a plurality of sub-liner bags that are formed together as one piece, with each sub-liner bag lining an associated sub-chamber. Each sub-liner bag is defined by a flange. The flanges of adjacent sub-liner bags are common, and solely by themselves, without any other attachments, attach the plurality of sub-liner bags to each other. The flanges of the plurality of sub-liner bags are divided lengthwise by perforations.

Abstract: A method for increasing the bandwidth within an air interface between a mobile station and a base station is disclosed. The method involves the seizing of multiple random access channels on the dedicated control channel between a single mobile station and the base station. Individual messages are then transmitted over each of the seized random access channels on a frame-by-frame basis. Up to six channels may be seized and utilized at any particular time.

Abstract: At least one layer of fibers of a material susceptible to heating by electromagnetic radiation is incorporated in a porous structure. The structure is subjected to the radiation to heat up the body which is contacted with hydrocarbon gas to cause the gas to deposit carbon within the porous structure and thereby cause densification.

Abstract: A device for supporting electrical cables and the like which includes a saddle for receiving and supporting the cables, and the saddles has a support surface formed with a rounded configuration that curves away from is centerline and downwardly from the centerline in both directions with a radius of curvature that provides a contour generally similar to the contour of the cables supported thereat.

Abstract: The present invention relates to a vibration absorber in which an absorber end mass is coupled to a primary mass by means of a cantilevered beam, wherein at least a portion of the beam comprises a shape memory alloy (SMA). Preferably, the end mass is coupled to the primary mass with several discrete SMA wires which may be individually heated. When each of the SMA wires is heated above a predetermined temperature, the SMA material undergoes a phase change which results in a change in the stiffness of the SMA wire. Heating of the various wires in various combinations allows the operational frequency of the absorber to be actively tuned. The frequency of the absorber may therefore be tuned to closely match the current vibrational frequency of the primary mass, thereby allowing the absorber to be adaptively tuned to the frequency of the primary mass in a simple and straightforward manner.

The present invention also includes the use of multiple fluorochromes for the detection of microorganisms and is adaptable for use in flow cytometry.

Abstract: Methods, systems and computer program products are provided which improve message processing in lost data circumstances for a communication system communicating over a wireless communication link by receiving part of a message which has been transmitted over the wireless communication link and determining if sufficient information was received in the message to perform an operation specified by the message. The operation is performed if it is determined that sufficient information was received in the message to perform the specified operation.

Abstract: A method for the densification of a porous structure comprises providing the structure with a body of material (13, 14) which includes a susceptor element foil (14) which is more susceptible to heating by electromagnetic radiation than the other material (13) of the body, exposing said porous structure to hydrocarbon gas and simultaneously applying an electromagnetic field to said porous structure whereby said susceptor element (14) at least in part causes heating of the porous structure to a temperature at which the gas infiltrating the porous structure deposits carbon within the porous structure.

Abstract: A method for the densification of an annular body having a porous structure and comprising layers of fabric, which includes locating a susceptor element within the porous body, the amount of the susceptor element occupying less than 5% of the volume of the porous body, the susceptor element being in the form of a layer comprising one of a foil and a fiber and having plural holes therein through which adjacent layers of fabric of the porous body contact each other, said susceptor element being made of a material which is more susceptible to heating by electromagnetic radiation than the material of the porous body, and exposing the porous body to hydrocarbon gas and simultaneously applying an electromagnetic field to the porous body, the susceptor element within the porous body at least in part causing heating of the porous body to a temperature at which the gas infiltrating the porous body deposits carbon within the porous body.

Abstract: A mobile communications device such as a pager or a cellular telephone enters a low power state more promptly than under TIA/EIA/IS-136 standards when an incoming message is pending for the device but is delayed by a first message broadcast for another such device. The device calculates the number of frames or SPACH slots required under those standards for the message for the other device; if that number is more than that reserved for the message for itself then it powers down immediately until the next paging channel slot is to be received. If the number of frames or SPACH slots required for the message for the other device is the same as or less than that reserved for the message for itself, then the device powers down immediately only for the duration of the message for the other device. By so powering down, the device achieves great savings in battery power as compared to present practices, without delay in reading incoming signals directed to the device.

Abstract: The disclosed apparatus is a stand alone integrated smart card circuit chip card vending machine. It accepts bills in $1, $5, $10, $20 and $50 denominations and/or credit cards and issues stored value smart cards for the value requested. It can also telephone a center to validate credit card transactions or send diagnostic and statistical reports. This invention has the capability to read and write to a card while it is in the dispenser stack, therefore the card has no value while in the dispenser and is not released until payment is received, that is, the cards are encoded in real time before they are issued.
