Abstract: A system, method and program code are disclosed for the unattended monitoring, retrieval and storage of online content by a mobile information processing system operating in a low power mode. An intelligent wireless modem is activated when a mobile information processing system is operating in a low power state. The intelligent wireless modem detects the availability of a predetermined wireless network and establishes a connection. Predetermined online sites and services are then monitored by an unattended online content processor for the identification, retrieval, and subsequent storage of predetermined content. The stored content is subsequently retrieved and presented to the user for review and other operations when the mobile information processing system enters an initialization state.

Abstract: A system and method is disclosed for wirelessly communicating displayable information for display on an auxiliary display device. A primary display device comprising a first display and a first wireless modem generates displayable information. The availability of one or more auxiliary display devices and information is collected to determine which of the auxiliary display devices are supported by the primary display device. The power state of the primary display device is monitored. If it is operating in a full power state, a full auxiliary display output mode is maintained allowing all, or a subset, of the displayable information generated by the first display device to be displayed on supported auxiliary display devices. If it is operating in a low or off power state, a subset auxiliary display output mode is activated and a predetermined subset of the displayable information is displayed on the supported auxiliary display devices.

Abstract: An apparatus and method is disclosed for integrating an information processing system and a portable communication device. A first information processing system is coupled to a second information processing system through a connection such as a dock, cable, or wireless link. Once coupled, an interface connection manager is implemented to enable the second system to perform processing operations using the first system's network connections and peripherals and vice-versa. The interface connection manager then establishes a communications channel between the coupled systems to a third information processing system, typically through a physical or wireless network connection. The interface connection manager similarly enables the first system to perform authentication operations by accessing an authentication module implemented in the second system.

Abstract: A catheter balloon for use in dilation procedures, such as angioplasty, has multiple pleats formed therein, preferably six such pleats, that may be folded, or wrapped, circumferentially around the catheter to provide a minimized outer diameter when the balloon is deflated. The balloon pleats form six wings in the balloon and each of the balloon wings has a length such that it overlaps a portion of an adjoining wing and each wing extends about one-quarter of the circumference of the catheter shaft. A device for forming such folds in a balloon includes a forming chamber and a plurality of forming elements radially disposed around the balloon.

Abstract: A communication system in which a multipart analog message (480) is generated by a controller (112) by including an analog part delimiter (440) between successive independent analog parts (420, 431, 432, 433). The multipart analog message (480) is positioned within a synchronous protocol, in which a digital code is included to identify the position of the multipart analog message (480). The synchronous protocol is transmitted by a radio transmitter (202) and received by a selective call receiver (122). The selective call receiver (122) digitally decodes the position of the multipart analog message (480) and begins recovery of the multipart analog message (480) at the position. The selective call receiver (122) recovers the part delimiters (440) and uses them to identify the independent analog parts (420, 431, 432, 433). One of the independent parts, which is a audible response, is selected by the user and used to generate a response.

Abstract: A frequency synthesizer which has at least one programmably characterized phase lock loop circuit includes a buffer memory and an interface controller responsive to operational codes received from a central controller to direct transfer of data words for characterization of the phase lock loop circuit among the at least one phase lock loop circuit, the buffer memory, and the central controller. In one embodiment, the transfer of data words between the central controller and phase lock loop circuit or buffer memory are performed serially in accordance with a prespecified protocol and governed by a clock signal generated by the central controller. Data word transfers between the buffer memory and at least one phase lock loop circuit may also be performed serially in accordance with a prespecified protocol, but may be governed autonomously by an internal clock signal generated by the frequency synthesizer.
