  • Publication number: 20050148362
    Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station, the mobile station being operable to roam between a private and a public network. The mobile station is signaled via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits. One or more features associated with a private network are delivered to the mobile station during the communication session as an end user moves between the public and private networks.

  • Publication number: 20050147088
    Abstract: Routing calls includes receiving a call request at a call manager from a first endpoint. The call request includes a uniform resource identifier that associates with a second endpoint. A determination is made whether the call request associates with the call manager that received the call request. To route the call request, the call manager searches a call search space for a match to the call request. The call manager communicates the call request to the routing target.

  • Publication number: 20040267099
    Abstract: In general, the invention is directed to a user interface for patient pain assessment. The user interface allows an operator to input and store a patient's pain assessment based on a given pain assessment scale. The invention may tranmit the pain assessment data along with patient physiological condition data to a remotely located hospital database. As part of the patient's medical record, pain assessment measurements can provide trending information similar to most physiological condition data, which may be useful for future treatment. The invention may prompt the operator with suggestions for treatment based on the pain assessment and physiological data collected. In some embodiments, the user interface may be applied to a defibrillator or a patient monitor.

  • Publication number: 20040152954
    Abstract: The invention is directed to techniques for configuration of a medical device, such as a defibrillator or patient monitor. The configuration is menu-driven. The medical device may present a menu of patient conditions to an operator. When the operator selects a patient condition from the menu, the device selects a configuration parameter and self-configures with the configuration parameter. The menu-driven techniques may further allow an operator to change the configuration of the device to configure the device more specifically to the condition of the patient. The menu-driven techniques may also allow the device to self-configure with a default configuration parameter in the event the operator fails to make a menu selection.

  • Publication number: 20040064342
    Abstract: The invention is directed to techniques for managing health care protocols with a device that may be brought to the site of a patient in need of medical assistance. The device, which may comprise, for example, a defibrillator or a patient monitor, selects a protocol as a function of patient data and presents information pursuant to the protocol to assist an operator attending to the patient. The invention further includes techniques for customizing protocols.

  • Patent number: 6644502
    Abstract: Certain designs of paper feeding devices used in copiers and printers require that an edge of a stack of sheets be in close contact with a slanted surface. An apparatus engages an opposite edge of the stack to urge the stack against the slanted surface, so that the stack assumes a parallelogram shape. The apparatus includes a plate which is movable from a vertical, upright position to a slanted position. Means are provided to cause the plate to move to the slanted position in response to the closing of a paper tray of a printer or copier.

  • Patent number: 6505006
    Abstract: In office equipment such as printers and copiers, a single machine “platform” is available as a number of distinct variants (copier, printer, facsimile, MICR printer). Different variants may require different types of marking material cartridges, or other replaceable units. To prevent the installation of an unsuitable cartridge in a machine, each cartridge defines a distinguishing configuration of convex or concave engagement structures, arranged in a circle, but whereby no more than one-half of the circumference of the circle is taken up by the engagement structures. The engagement structures engage with complementary structures inside a suitable machine, and can assist in driving a rotation of the cartridge within the machine.

  • Patent number: 5172691
    Abstract: A pacemaker/monitor (10) is disclosed for applying a pacing current to a patient through a pair of pacing electrodes (12). The pacemaker/monitor includes a plurality of manual inputs (26) for use by an operator and a microprocessor (16) that responds to programmed instructions stored in read-only memory (20). Cooperatively, these components control the operation of the pacemaker/monitor. In that regard, the desired magnitude of the pacing current in input to the pacemaker/monitor via a limitless rotary current control (46), formed by a rotary pulse generator (52) and a decoder circuit (50). The microprocessor monitors the operation of the various manual inputs and sets the pacing current to zero milliamperes in the event one of the inputs is used, regardless of the position of the rotary pulse generator. For example, when the pacemaker/monitor is turned ON, or the pacing mode of operation is selected, the pacing current is zeroed.
