  • Publication number: 20130076567
    Abstract: A system, methods, and apparatus for dual antenna transfer switching are disclosed. In an example embodiment, a dual antenna system includes antennas, antenna control units, a transfer switch, and a modem. For example, the transfer switch may transfer a connection between antennas based on changing satellite visibility, upon entering a preprogrammed blockage zone or an unexpected loss of satellite visibility. The transfer switch may receive GPS data from an external GPS unit and/or the antenna control units and buffer the GPS data to a modem. The transfer switch may provide a modem receive-lock signal to retarget a line of sight. The transfer switch may transfer the connection between the antennas based on satellite visibility including signal reception quality and/or a modem receive-lock status. The transfer switch may, based on a difference in antenna uplink transmission power, attenuate a higher power antenna to be balanced with a lower power antenna.

  • Publication number: 20060112165
    Abstract: A first party (e.g. educational testing service) provides through the internet to a control server information (e.g. test server) relating to a second party (e.g. a student taking tests prepared by the service). The server provides and may store a verification (e.g. an encrypted digital signature) of, but does not store, the second party information. The server transmits the information and the verification through the internet to the second party. The second party transmits to the server through the internet the information and the verification with a request to transmit the information to a designated third party (e.g. a college or university to which the student has applied for admission). The server authenticates the information through verification comparisons (or through comparison of the information with the reconstruction and decryption of the verification) and transmits the information, authenticated by the server and the testing service, to the third party.

  • Patent number: 6772784
    Abstract: A proportional pressure regulator assembly having a main body with a first inlet adapted for fluid communication with supply of positive pneumatic pressure, a second inlet adapted for fluid communication with a supply of negative pneumatic pressure, an outlet adapted for fluid communication with a pneumatically actuated device, and an exhaust port is provided. A fill regulator valve is included that is adapted to regulate the supply of positive pressure. A vacuum regulator valve is included that is adapted to regulate the supply of negative pressure. An exhaust valve is included that is operable to exhaust pressure from the outlet. A control circuit assembly is also provided that is adapted to receive a command signal and a feedback signal and to regulate the amount of positive pneumatic pressure through the fill regulator valve or the amount of negative pneumatic pressure through the vacuum regulator valve in response to the feedback signal.

  • Patent number: 6665871
    Abstract: A system for reprogramming a consumer electronic device includes a consumer electronic device (CED) having a CED processor and a CED memory and a CED serial port connected to the processor, the memory storing CED processor instructions and CED data. The system also includes a download module having a download processor and a download memory and a download serial port connected to the download processor. The CED processor periodically applies a signal to the CED serial port. When the download serial port is connected to the CED serial port to make a serial connection and the download processor receives one of the periodic signals from the CED processor, the download processor initiates the download of one or more of download instructions and download data from the download memory to the CED memory over the serial connection.

  • Patent number: 3951953
    Abstract: Complexes of a semi-synthetic penicillin and an anion exchange resin cross-linked less than 4% and wherein the penicillin, with or without a non-complexed additional penicillin, is absorbed onto and in the ducts or channels in the resin particles substantially all of which have diameters between 20 .mu. and 250 .mu.. The semi-synthetic penicillin constitutes 35-65% of the complex. The complexes are formulated as pharmaceutical compositions which can be in tablet or syrup form. The penicillin is released rapidly and completely and is free of unpleasant taste.
