An control interface and system is provided that allows users to use a handheld device to communicates with an electronic billboard through a host server. The interface allows users to display information, as well as interact with information that is displayed on the electronic billboard. In order to establish this communication, a user, through their handheld device, communicates with a host server, which provides them with one or more available services that they can invoke in order to communicate with the display.

An ultrasonic diagnostic imaging system and method are described in which spatially compounded images are produced by transmitting ultrasound beams in different directions during a common transmit-receive interval. Echoes are received from the different beam directions and are beamformed by a multiline beamformer to produce differently steered beams of coherent echo signals. The echoes are combined on a spatial basis with echoes from different look directions which correspond to the same spatial location being combined. The resulting spatially compounded image is displayed.

An ultrasonic diagnostic imaging system produces an image with an extended focal range by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned and are combined with phase adjustment between the respective receive multilines to prevent undesired phase cancellation. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. To prevent motion artifacts the multiline order is adjustable as a function of image motion.

The invention relates to piezoelectric resonators. An interposer element is used between a resonating plate and the resonator package to provide improved (i.e. reduced) acceleration sensitivity. The interposer element is preferably of similar thermal expansion characteristics to the resonating plate. Electrical connection to the resonating plate from the exterior of the package is preferably provided via the interposer element.

Each transducer element of a transducer array in an ultrasound imaging system has two substantially identical analog delay circuits, the first of which is supplied with the echo signal received by the transducer element, the second of which is supplied with an inverted version of the echo signal received by the transducer element. After both signals have traversed their respective analog delay paths, one of them is inverted and then both of them are combined in order to substantially suppress the effects of localized common mode signals. Preferably, the first and second analog delay circuits are constructed to be substantially identical.

In an advanced intelligent network based information distribution system including a central office switching system connected to communication lines including at least one service switching point for selectively providing switched communications between the communication lines, a network controller arranged for selectively providing control data to effect land line communications, and arranged separately from the central office switching system, an incentive award computer system provides an award to users participating in an incentive award program. The incentive award computer system includes a request transaction processing computer system receiving an electronic transaction by a user, determining whether the electronic transaction is a reward eligible transaction, and generating a transaction request when the electronic transaction is determined to be the reward eligible transaction. In addition, a points calculator processing computer system is provided that determines a reward responsive to the reward eligible transaction represented in the transaction request, assigns the reward to a user record responsive to reward criteria, and generates a reward record representing the reward. The incentive award computer system further includes a points assigning and reporting processing computer system that generates reports and provides access to the user record and the reward by the user responsive to predetermined criteria.

摘要:
A synthetic focus ultrasound system is described which is operated in a hybrid fashion. System operation alternates between synthetic focus acquisition and conventional focused beam acquisition. This makes possible, for example, the acquisition and display of harmonic images. Speckle artifacts in the synthetic focused ultrasound images may be reduced by combining signals from different sub-apertures which view the image field from different look directions. In a described embodiment, sets of motion maps are be produced for different sub-apertures of the array transducer, then compounded to reduce speckle. One or more identified regions of interest within a synthetic focused ultrasound image may be processed differently from other regions of the image to highlight or better define particular motional characteristics within the regions of interest, such as turbulent flow or different velocities of flow or motion.
