Abstract: A wireless terminal identifier and an alternate routing identifier are associated with a wireless terminal. When an incoming communication is directed to the wireless terminal identifier, it is routed based on the alternate routing identifier when the wireless terminal is not available.

Abstract: An ultrasound imaging system is provided with a vector compounder and a vector splicer for respectively compounding and splicing vector data from multiple firings along a scan line to improve image quality. The compounder consists of an accumulator which sums the vector data of at least two vector data sets and then scales the summed vector data by a scaling factor. Preferably, the scaling factor equals 1/n, where n is the number of vector data sets being summed. The splicer splices compounded vector data to form a single output vector data set in accordance with a weighting function that splices vector data from a first compounded vector data set for a firing having a first range of maximum focus and vector data from a second compounded vector data set for a firing having a second range of maximum focus with a transition region therebetween. The vector data from the first and second compounded vector data sets are combined in the transition region using a piecewise linear weighting function.

Abstract: A method and apparatus for controlling multiplexing of a transducer having more elements than the imaging system has receive channels. The active aperture is shifted in increments of a predetermined number of transducer elements, e.g., eight. While the active aperture is maintained constant for a predetermined number of vectors, the phase center of the vectors in the group is shifted so that offset is minimized. In the case wherein the active aperture is successively shifted by eight elements, the offset is varied between +4 and -4 during the interval between shifts of the active aperture.

Abstract: A method and an apparatus for activating one of a plurality of connected transducers in response to the operator picking up that transducer. This enables the selection of a transducer without the need for pressing a button or key. Automatic selection is accomplished by placing a proximity sensor located within the holder of the transducer or on the transducer itself to indicate whether the transducer is being held by its holder. Switches are also incorporated to detect when a transducer connector has been plugged into each port on the ultrasound imaging machine. Depending on the order in which unactivated normal transducers attain a state whereby the respective normal transducer is both connected and out of its holder, a stack of probe identifiers is created. Identifiers for connected special transducers are added to the stack below any probe identifiers for normal transducers. The identifier at the top of the stack indicates the transducer which will be activated next, i.e.

Abstract: An acoustic power control technique computes relevant system transmit parameters in real-time by optimally combining a current system imaging configuration with an empirically derived measurement database. The database contains measurement information that is used by the acoustic power control technique to determine optimal transmit parameters for a given imaging situation. The optimal parameters are determined by adjusting the measured database parameters through the use of the current scanning parameters to maximize system performance. Utilizing system constraints, the acoustic power control technique computes the optimal transmit parameters to maximize system performance.
