Abstract: An RF data communications device antenna system is shown that includes a dipole and an electromagnetic coupler that provides coupling between each dipole arm to establish a desired resonant bandwidth. An LC matching circuit is provided for matching the dipole to the impedance of the RF data communications device and for transforming the RF signal between the dipole arms of the antenna system.

Abstract: A wireless radio modem for incorporation into a host system includes radio frequency modulation/demodulation circuitry employing electronic device elements that operate in a frequency range that minimize the RF interference between the radio modem and the host system. Radio modem power conservation is further maximized by 1) simplifying signal modulation processing by use of a single sideband suppressed carrier waveform transition table, thereby reducing processing requirements; and 2) incorporating a "sleep mode" feature in which all non-timer circuitry is powered-down when not in use.

Abstract: A device is provided that interfaces with existing point of sale credit card reading devices, and furnishes the option of transmitting data over either the existing modem installation or a radio frequency data communication network. The device scans the information encoded on the credit card to determine which data transmission path is appropriate for a particular transaction. The device software generates the necessary signals to simulate the normal interaction between the POS cardreader device and a modem. The software also converts between serial and packetized data in order to request and receive credit card purchase authorizations over the radio frequency data communication network.

Abstract: A radio telecommunications antenna includes a telescoping antenna portion for substantially receiving an electromagnetic signal. The telescoping portion is attached by an antenna mast for conducting the electromagnetic signal. A dielectric spacer and an inductor are in electrical contact with the antenna mast. An RF connector is in electrical contact with the dielectric spacer, opposite the antenna mast, so as to form a capacitor. The RF connector is also in electrical contact with the inductor so that the capacitor and the inductor form an LC circuit with values selected to provide a predetermined impedance match with the remainder of the antenna.

Abstract: A method of manufacturing confetti includes stacking a plurality of sheets of lightweight material into a stack, placing an open ended gang die onto the stack, applying pressure to cut the stack into plurality of shaped stacks, and bursting each of the shaped stacks to separate the sheets from one another. The open ended gang die is formed by welding individual dies onto metal pull bars of a gang die.

Abstract: A wireless radio modem that may be incorporated into a host system or connected through a PCMCIA or similar port to a host system includes radio frequency modulation/demodulation circuitry employing electronic device elements that operate in a frequency range that minimizes the RF interference between the radio modem and the host system. Radio modem power conservation is maximized by 1) simplifying signal modulation processing by use of a two-point waveform transition table, thereby reducing processing requirements; and 2)incorporating a "sleep mode" feature in which all non-timer circuitry is powered-down when not in use.

Abstract: A method and system provides a special purpose or embedded system developer with the ability to confirm the correct operation of a computer program designed to operate on a target system whose processing and storage capabilities may be more austere than the host system upon which the computer program is designed and tested. A key feature of the method and the system enables a developer to execute and debug an application program on a host system while observing and testing the operation of the program through the input/output of the target system. Another feature of the method and system is an application loader that dynamically sizes and, as necessary, reconfigures the available memory to permit multiple applications to reside simultaneously on the target system by resolving addresses in the target system at the time an application of interest is downloaded to the target system.

Abstract: The present invention provides a method for enhancing service signals transmitted by a DCE, such as a Modem, to a DTE user. Since any transmission from a remote computer to a DTE user through a wireless communication network can be encoded with additional information, use of an AT compatible modem in conjunction with a wireless communication network adds a new dimension of information that can be displayed to the DTE user. The present invention also includes a method for ensuring effective data transfer from a DCE to a DTE user. When a DTE receives a connection service signal it will often require several internal adjustments before it can accept data. Because data received by a radio-based modem is received in packets, under certain conditions data will be waiting to be transmitted to the user immediately after the modem enters a data transfer state.

Abstract: A feed cloth and bottle combination includes a cloth sized to be draped over a user's shoulder. An area of the cloth includes a first of a hook and loop fastener. A strap is secured to a baby bottle with an exterior surface of the strap having a second of a hook and loop fastener such that the strap and the bottle can be secured to the cloth with the bottle held in any desired orientation.

Abstract: The present invention provides a method for user control of a gateway in a wireless data communicator network. The present invention includes transmitting a data packet to the gateway, including control data continuing a plurality of commands to be executed by the gateway. The gateway then parses the plurality of commands and executes the commands.

Abstract: Clothing items including at least one sewn-in liquid cushioned bladder conforming to one or more pressure points experiencing friction or repeated shocks. Distributed through vents and sealed islands define one or more endless channelways to facilitate moisture transfer and assure even liquid distribution with body movement. Associated vented, wicking coverings transfer perspiration away from the bladder and wearer. Preferred embodiments include pantswear, gloves and an improved bladder containing seat cushion.
