Abstract: A phased array antenna system having a corporate waveguide distribution network stripline printed circuit board. The stripline printed circuit board receives electromagnetic (EM) wave energy from a 1×4 waveguide distribution network input plate and distributes the EM wave energy to 524 radiating elements. The stripline circuit board enables extremely tight spacing of independent antenna radiating elements that would not be possible with a rectangular air filled waveguide. The antenna system enables operation at millimeter wave frequencies, and particularly at 44 GHz, and without requiring the use of a plurality of look-up tables for various phase and amplitude delays, that would otherwise be required with a rectangular, air-filled waveguide distribution structure. The antenna system can be used at millimeter wave frequencies, and in connection with the MILSTAR communications protocol, without the requirement of knowing, in advance, the next beam hopping frequency employed by the MILSTAR protocol.

Abstract: An apparatus and method for compressing and compressing text based messages. A TCCB layer 114, 115 is added to a mobile device 100 and P-CSCF 102. At the sending device, the TCCB compression method is invoked to remove all redundant header information contained in a message to be transmitted. When the TCCB compression method detects that a header's contents are the same as previously sent or received for a particular sequence, the TCCB method blanks the header contents. At the receiving device, when the TCCB layer receives a message with blank header contents, the TCCB decompression method is invoked to reconstruct the header from its cache 115, 127.

Abstract: A system for deriving funds for a financial vehicle such as an investment fund on behalf of a customer comprises means for inputting data on financial transactions to a customer account. The processor running the account increases the value of each transaction as to an amount related to the amount of the transaction by rounding it up to the nearest pre-set currency unit value and adds the increase in the amount to a notional accrual account. At the end of an accounting period the entries in the accrual log are totalled, debited to the money transmission account and transferred to the financial vehicle on behalf of the customer automatically.
