摘要:
A system for injecting I/O faults into a closed system, for example, the injection of link level I/O faults, involves the use of a simulated computing environment. In an embodiment, the system provides for fault injection using an emulated IBM System z environment and including the use of FICON and/or other suitable communication channel protocols. The emulated System z environment may include a simulated z/OS and/or emulated System z hardware and software components.

A communication card includes a retractable connector that is smoothly extendable and retractable. A torsion spring is positioned within a slot that receives the retractable connector and the torsion spring assists the extension of the retractable platform and counter forces that may otherwise cause the platform to bind as it extends and retracts. A flexible circuit is attached to the torsion spring and it allows electrical communication between the retractable connectors and the communication card. The flexible circuit is preferably attached to the retractable connector and the communication card by zero insertion force connectors. Because the flexible circuit is bonded to the torsion spring, the movement of the circuit is constrained and that helps protect the circuit from damage.

An apparatus for facilitating the various placement of an antenna within a wireless transceiver device such as a wireless personal data assistant is presented. Such an apparatus enables the relocation of an antenna device in accordance with a user preferred configuration. The relocation of the antenna device does not effect the overall performance and does not require further termination of unused antenna configurations. Such an apparatus facilitates the preferred placement of an antenna in accordance with a user's hand preference (e.g., right handedness verses left handedness).

An expansion bullet for a heat exchanger tube includes a leading edge face, a trailing edge face, and a bullet body insertable into a tube of a heat exchanger to expand the tube. The bullet body extends from the leading edge face to the trailing edge face and has an outer profile defined by a single radius. An expansion mechanism for a tube of heat exchanger includes a bullet driving device and an expansion bullet drivable by the bullet driving device. The expansion bullet includes a leading edge face, a trailing edge face, and a bullet body insertable into a tube of a heat exchanger to expand the tube. The bullet body extends from the leading edge face to the trailing edge face and has an outer profile defined by a single radius.
摘要:
An integrated diversity antenna solution is presented that positions multiple antennas within the digital device case. The integrated diversity antenna solution works equally well with diversity radios, such as 802.11, and non-diversity radios, such as Bluetooth. The non-diversity radios are supported via a power splitter attached to the antennas that give the necessary directional coverage. The integrated antenna array solves the main problem associated with wireless communication on laptop computers, specifically, that laptops perturb the radiation pattern because of the influence that laptop components have on standard antennas and the presence of interfering objects, most notably the laptop user, in the surrounding environment.
摘要:
The present invention discloses antenna structures for portable digital devices that continuously receive radio signals in both the extended and the retracted antenna positions. In addition, the disclosed antenna structures tune the antenna based on the position of the antenna to achieve good impedance matching, which is particularly useful in reducing the noise and interference, while maximizing the available power for radiation from the portable digital devices. More specifically, a multiple position stylus antenna is disclosed that incorporates an antenna into a stylus for use with a Personal Digital Assistant (PDA). The stylus antenna uses one radiating element tuned for optimal performance in the extended position and synthesizes a compensation impedance to match the impedance of the feeding transmission line in the retracted position.
