A system for transmitting aircraft data from an aircraft includes a Data Acquisition Unit (DAU) that records aircraft data. A PC card is interfaced to the DAU and stores the aircraft data from the DAU. A processor retrieves aircraft data from the memory. A first wireless transceiver is controlled by the processor and receives and transmits the aircraft data along a wireless communications signal. A wireless local area network (LAN) communications unit is configured as an access point and positioned within the aircraft and transmits and receives wireless communications signals to and from the PC card. A second wireless transceiver is mounted within the aircraft and receives the wireless communications signal from the wireless LAN communications unit for transmitting the aircraft data from the aircraft.

The present invention includes a balanced compact antenna, conforming to the envelope restrictions appropriate to a PC-card form factor, with maximum radiation intensity along a long axis of the card. The inventive antenna configuration employs an inductive shorting bar to match an “M”-shaped bent dipole antenna to a differential feed. The combination of horizontal cross-members and large vertical downward legs ensures radiation predominantly in a broadside direction while keeping the dimensions of the antenna sufficiently compact to fit within the PC-card envelope.

A casing for enclosing a circuit board comprises pair of symmetrical halves assembled together. Each said half forms plurality of retaining means on a first longitudinal side thereof and plurality of receiving means at a second longitudinal side opposite said first longitudinal side whereby said halves are fixedly assembled together by the interlocking engagement between said retaining means and said receiving means.

A PC card video recorder. The conditional access functionality of a Point Of Deployment module (POD) is augmented by providing solid state memory on a PC card for recording and playback of programming. An encrypted video stream from a television Set-Top Box (STB)or other appliance is decrypted in the PC card. The decrypted video stream is then filtered to remove information not relevant to a program to be stored. The filtered video stream is then applied to the solid state memory. During playback, the video stream is retrieved from the memory and encrypted prior to transmission to the STB. Intra-pictures can be played back rapidly to provide a fast forward mode by reference to a table or packet header storing starting and ending address of the intra-pictures. Multiple POD card interfaces can be provided in the STB to accept multiple PC card recorders. Pairing security can be provided by checking a recording STB identifier against a playback STB identifier.

A security system including a removable circuit card having an unauthorized movement detection subsystem including a motion sensor, a processor responsive to the motion sensor for detecting whether motion sensed thereby is indicative of unauthorized movement and a response circuit activated by the processor in response to unauthorized movement. The security system also includes a power source integrated with the circuit card for powering the unauthorized movement detection subsystem in the event of a lack of available external power including removal of the circuit card.

Real-time data and event management (RDEM) is implemented on a separate component in supervisory control and data acquisition (SCADA). To assist in upgrades or changes to the SCADA system without compromising RDEM, the RDEM function is performed on a separate card or physical component. When the computer running the SCADA system is upgraded, the RDEM on the separate card and corresponding persistence store is maintained.

A controller includes a plurality of readers for reading an associated plurality of expansion cards and for controlling operation of such expansion cards, wherein at least one of the plurality of readers is a flash media reader. A method for controlling the operation of at least one expansion card with an integrated controller having a plurality of readers includes detecting the presence of at least one expansion card, and enabling a selected reader of the integrated controller associated with at least one expansion card. Another method of writing data to read only memory in an integrated controller includes unlocking the read only memory, writing information into the read only memory, and locking the read only memory to prevent otherwise unintentional or unauthorized writing to the read only memory is also provided.

A multi-band antenna system for a portable communications device (e.g. a PC Card wireless modem) is disclosed. The multi-band antenna system comprises a dipole antenna, a reactive circuit, and transmission means coupled between the reactive circuit and the dipole antenna. For signals having frequencies within a first frequency band (e.g. the CDMA 0.86 GHz band), the reactive circuit operates as a trap, i.e. as a substantially high impedance, which enables a radiation impedance of a monopole formed by the presence of the trap to be coupled directly into the feed system (e.g. a diplexer) of the antenna system. The dipole antenna is configured and dimensioned to receive signals within a second frequency band (e.g. the PCS 1.92 GHz band). Second frequency band signals received by the dipole antenna are conducted through the signal conductor of the transmission means to the feed system substantially unimpeded by the reactive circuit. The multi-band antenna system may further include a diversity antenna, which may be configured so that it is polarized orthogonal the to dipole antenna.

A PC card control apparatus includes a PC card connector, a card detector and an interconnection switching circuit. The PC card connector is configured to provide connections for connecting one of a first PC card compliant with specific card standards and a card-adapting card for connecting a second PC card compliant with a different card standard to the PC card control apparatus. The card detector is configured to detect connection of the card-adapting card to the PC card control apparatus and to subsequently output a detection signal. The interconnection switching circuit is configured to switch the connections of the PC card connector to connect the PC card connector to a bus interface dedicated to the second card upon receiving the detection signal from the card detector.

An RFID reader accessible thorough a personal computer and includes a PC card interface and a controller both operating according to clock signals from a crystal oscillator. The RFID reader further includes a linearized power amplifier modulator in a transmit path, a receive chain capable of demodulating either class_1 or class_0 signals from RFID tags, and an integrated switching device for selecting one of a plurality of antenna for transmitting or receiving RF signals.

An electronic device for wireless communications, which may typically be a PC card 21, is adapted to upwardly turn the direction of radiation of the radio wave radiated from an antenna regardless of the mounted position of the antenna. The PC card 21 is contained in or removably fitted to a personal computer 11 so as to provide the personal computer 11 with wireless communication functions.

A motion detector is provided that enables power to a computer module to be disconnected prior to removal of the module from the connector. Actuation of a sensor causes a shutter assembly to move vertically. The shutter assembly is in communication with a switch. Movement of the shutter assembly causes actuation of the switch to send a signal to a control circuit of an associated controller. Power to the controller is provided when the shutter assembly is in communication with the switch, and power is removed from the connector when the shutter assembly is not in communication with the switch.

This Invention permits very rapid installation of operating systems onto off-the-shelf hardware. Furthermore, this Invention addresses multiple configuration issues pertaining to the creation of unique “InterNet Hosts”, and thus enables the very rapid installation of operating systems preconfigured to boot into a “ready to internetwork” mode with no subsequent configuration needs. It integrates several different existing security and encryption models which are considered robust. Further, the media on which this Invention will be distributed, and from which it will be run, are read-only CD-ROM, providing further defense against InterNet-based attacks. A variety of scripts generates a series of CD-ROMs which will each boot an Intel-ix86-based PC to an individual network identity, all of which will have the characteristics listed above, and will automatically network if provided with the IEEE 802.11b standard wireless PC Cards.
