  • Publication number: 20050071235
    Abstract: A system for providing distributed control to process transactions is disclosed. The system includes a service provider system having associated therewith a number of rules and a number of meta-rules, a point of service device having associated therewith a number of rules and a number of meta-rules, and a portable device having associated therewith a number of rules and a number of meta-rules. The portable device uses its associated rules to determine an outcome for a transaction. If the portable device is unable to determine the outcome for the transaction, the portable device uses its associated meta-rules to either determine whether one or more of its associated rules can be altered locally in order to determine the outcome or request the point of service device to help determine the outcome using the rules and meta-rules associated with the point of service device.

  • Publication number: 20050058427
    Abstract: A system for facilitating image management for portable devices is disclosed. The system includes a host configured to maintain information relating to a first portable device and a second portable device and an interface device configured to communicate with the host and the first and second portable devices. The interface device includes control logic configured to: determine whether the first portable device is valid for image synchronization using information provided by the host; and if it is determined that the first portable device is valid for image synchronization, record an image of the first portable device, determine whether the second portable device is valid for image synchronization, and download an image of the first portable device to the second portable device if it is determined that the second portable device is valid for image synchronization.

  • Patent number: 5555887
    Abstract: A multiplane TEE probe is provided in which an aluminum sheet is embedded in the acoustic lens in front of the transducer to dissipate heat which accumulates in the lens. The embedded aluminum foil sheet in front of the transducer helps reduce such heat buildup by spreading out heat which develops at hot spots and conducting the heat trapped in the lens material to a heatsink mass behind the transducer and away from the patient contacting surface of the probe. A mylar sheet covers the front of the transducer. The inner surface of the mylar sheet is aluminized. This aluminum layer in the inner surface of the cover serves a like purpose.

  • Patent number: 5402793
    Abstract: A multiplane TEE probe is provided in which rotation of the ultrasonic transducer is motor controlled. The motor is controlled to rotate the transducer either clockwise or counterclockwise, and at either a high rotational speed or a low rotational speed. The motor is also automatically controlled to drive the transducer to a predetermined home position. The transducer tip of the probe is detachably connected to the gastroscope tube. An aluminum sheet is embedded in the acoustic lens in front of the transducer to dissipate heat which accumulates in the lens. The gastroscope tube includes an articulating section formed of a plurality of matching cylindrical links which form alternating pivot axes from one link to the next. The pivot range of each link with respect to an adjoining link is controlled by opposing limit stops orthogonally located with respect to the pivot points of the links.
