  • Patent number: 7283860
    Abstract: An injector system for injection of a fluid medium into a patient within an electromagnetic isolation area. The injector system includes a powered injector, a system controller therefor, and a plurality of communication units. The powered injector is positioned within the isolation area. A first communication unit integral with the powered injector enables the first communication unit and the powered injector to be moved as a unit. The system controller is positioned outside the isolation area and has a second communication unit integral therewith. An intermediate communication unit ensures communication between the first and the second communication units and therethrough between the powered injector and the system controller using an authentication technique therewith. The first, second and intermediate communication units are adapted to communicate by transmission of radio frequency (RF) energy. The RF energy is chosen to avoid interfering with the operation of MRI scanners.

  • Publication number: 20070112265
    Abstract: A fluid injection system includes an injector comprising a drive mechanism and an illumination device, a fluid container operably associated with the drive mechanism, and a control device operably associated with the drive mechanism. The control device comprises a computer screen having at least one element affiliated with the illumination device. The illumination device and the at least one element emit light of the same color. Further, a method of operating an injector system providing visual stimuli corresponding to a programmed injection protocol includes perceiving visual stimuli provided by an injector or a control device of the injector system, recognizing a pattern provided by the visual stimuli, correlating the recognized pattern to the programmed injection protocol, determining whether the programmed injection protocol is a desired injection protocol, and initiating the programmed injection protocol, if it is determined that the programmed injection protocol is the desired injection protocol.

  • Publication number: 20060003785
    Abstract: One or more wireless devices operate in an environment having a central manager that controls communications. The wireless devices include respective identifiers and the central manager maintains an association table identifying which identifiers are associated with which other identifiers. The wireless devices are permitted to communicated only with other wireless devices as indicated in the association table.

  • Publication number: 20050286717
    Abstract: A headset assembly includes a moisture-proof and temperature resistant headset module. The headset module is sealed against moisture and is constructed from materials that are durable and can withstand constant use, physical abuse, and rapid swings in temperature and other environmental conditions. Furthermore, the headset module is interchangeable with a variety of headset frames so as to provide comfort during prolonged use and in high ambient noise environments.

  • Publication number: 20050272401
    Abstract: A wearable, mobile and/or portable terminal for use in an inventory management system. The terminal includes a terminal housing, a battery pack removably receivable within an external battery-receiving cavity of the terminal housing, and a battery latching mechanism that secures the battery pack in the battery-receiving cavity in a latched condition. The battery pack has an unlatched condition in which the battery latch mechanism is disengaged from the battery pack. The terminal and battery pack are environmentally sealed to, for example, preclude entry of water into the interior of the terminal when the terminal is immersed.

  • Publication number: 20050095899
    Abstract: A communication system includes a voice-directed portable terminal with a voice user interface that is configured for being able to communicate with a computer system. The communication system includes a peripheral device having a cord coupled with the portable terminal and a connector adapted to disconnect from the portable terminal when a sufficient force is applied to the cord. This disengages the peripheral device from the portable terminal. The ability of the cord to break-away from the portable terminal prevents damage not only to the connector, but also to the cord, peripheral, and terminal.

  • Patent number: 6704592
    Abstract: A communication system for use in an MRI procedure includes a first communication unit positioned within a shielded housing on an interior side of the isolation barrier. The first communication unit includes a first receiver and a first transmitter. The communication system also includes a second communication unit positioned on an exterior side of the isolation barrier. The second communication unit includes a second receiver and a second transmitter. The first communication unit is in connection via optical cabling with a first light transmitting device positioned on an interior side of the isolation barrier adjacent a viewing window in the isolation barrier. The second communication unit is in connection via optical cabling with a second light transmitting device positioned on the exterior side of the isolation barrier adjacent a viewing window in the isolation barrier.
