摘要:
A method of synchronizing a plurality of data streams. A land mobile radio (LMR) data stream can be generated by a LMR communication device. At least one LMR identifier can be communicated from the LMR communication device to a broadband communication device. A broadband data stream can be generated by the broadband communication device. The broadband data stream and the LMR identifier can be communicated from the broadband communication device via an access network. The LMR identifier can enable synchronization of the LMR data stream with the broadband data stream.

A method to transmit a broadband multimedia resource locator using a narrowband communication system embeds the broadband multimedia resource locator into a narrowband audio stream and transmits the narrowband audio stream to one or more receiving communication devices over the narrowband communication system. The receiving communication device(s) subsequently extract the broadband multimedia resource locator from the narrowband audio stream and use the broadband multimedia resource locator to access a broadband communication system to retrieve multimedia content.

A method for enabling group communications includes: establishing a group identity for a communication group comprising a first set of communication devices, and storing an identity for each of the communication devices in the first set; establishing a session to associate a second set of communication devices with the group identity, wherein the communication devices in the second set are different from the communication devices in the first set, wherein the session with the second set of communication devices is set up irrespective of a call being initiated for the communication group; detecting a first event associated with the initiation of a call for the communication group; and in response to detecting the first event, using the stored identities to join at least one of the communication devices in the first set to the session.

A PTT bridging gateway between a first PTT system and a second disparate PTT system: receives an invitation to a first client to join a first group call for a first group comprising multiple member clients on the first PTT system, wherein the first client is one of the member clients of the first group; determines that the first client is mapped to a second group comprising multiple member clients on the second PTT system; and initiates a second group call to the multiple member clients on the second PTT system.
摘要:
Methods for increasing encryption synchronization availability include collecting encryption synchronization data from a first superframe received at a gateway. The encryption synchronization data is for decrypting media in a second superframe also received at the gateway. The encryption synchronization data from the first superframe is used to form a composite encryption synchronization codeword for decrypting media in a third superframe formed by the gateway, wherein the third superframe includes the composite encryption synchronization codeword and at least a portion of the media from the second superframe. The third superframe is sent to a receiving device so that media in the third superframe can be decrypted by the receiving device using the composite encryption synchronization codeword that is included in the same superframe as the media that is being decrypted.

摘要:
Disclosed is a drug delivery infusion pump assembly containing a drug delivery pump, a drug delivery cassette, a pump door, and a housing adapted to receive a drug vial. A drug vial centering mechanism ensures varieties of drug vial sizes are compatible with this device. The drug delivery cassette is capable of being positioned on the drug delivery infusion pump assembly so the drug delivery pump will interface with a drug delivery tube located on the drug delivery cassette.
摘要:
An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. Rotational positioning of an elongated portion and end-effector is achieved by the provision of a clutch mechanism incorporated into a housing apparatus. The arrangement permits the elongated portion to be rotatably positioned with respect to the apparatus housing and permits rotation of a the end-effector relative to the elongated portion.

Various mechanisms, and a method of operating them, are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by means of the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation. In the first angular orientation, the fastener advancing member is restrained against longitudinal movement to assist in installation of the cartridge onto the instrument. The distal end of the instrument can be articulated, and a helical gear operator is provided for effecting the articulation. The helical gear pitch decreases in a direction such that the mechanical advantage is increased as the articulation angle increases. A trigger actuating system includes a trigger lever with a cam channel, a pin in the cam channel, and a link connected at one end to the pin and at the other end to a reciprocatable driver. A frame is provided with a guide channel for guiding an end of the pin. The trigger lever is pivotally mounted to the frame and biased to a normally unactuated position.
