摘要:
An ultrasonic transducer probe (12) uses one or more ribbon cables (100) to attach the transducer elements (312) to the probe wiring. Electrical conductors within a first ribbon cable (100-1) attach to corresponding lands (410) on an end of an integrated circuit (310) and, electrical conductors within additional ribbon cables attach to corresponding lands (404) on circuit boards (308). The circuit boards (308) distribute the electrical signals from the attached ribbon cables to additional lands (410) on another end of the integrated circuit (310).

A micro-machined ultrasonic transducer (MUT) substrate that reduces or eliminates the lateral propagation of acoustic energy includes holes, commonly referred to as vias, formed in the substrate and proximate to a MUT element. The vias in the MUT substrate reduce or eliminate the propagation of acoustic energy traveling laterally in the MUT substrate. The vias can be doped to provide an electrical connection between the MUT element and circuitry present on the surface of an integrated circuit substrate over which the MUT substrate is attached.

A method is provided for a wireless message receiving apparatus to selectively and independently respond to received messages having multiple directory numbers associated therewith. Each directory number associated with the wireless communication unit is considered to be associated with one of a plurality of user personas or identities. For example, a first directory number may be associated with a 'worker' identity, a second directory number may be associated with a 'homemaker' identity and so on. When a caller dials one of the directory numbers, the caller is considered to be accessing the associated user persona. The communication unit, upon receiving a call, responsively identifies the persona that is being accessed and independently responds in accordance with a pre-stored general disposition instruction. An exception list for each directory number is provided which is used to respond to callers for whom the user wishes to respond in a different manner.

An ultrasound imaging system (100) in which a user determines a desired ultrasound image (306) to view and communicates (138) that desired view to the ultrasound imaging system (100) is disclosed. The ultrasound imaging system (100) analyzes the request and determines the appropriate scan slices (302, 304) to project to obtain the desired image (306). The desired image (306) approximates a three dimensional view, but is developed without the necessity of obtaining a three dimensional volume set of data.

The invention relates to a method of analyzing a medium in order to label the zones of said medium as a function of the contents of said zones, which medium is exposed to ultrasound signals. The method includes a step for receiving echographic ultrasound signals by means of a set of elements, thus defining a set of received signals, a step for correlating at least one pair of signals which are received by two elements from among the set of elements and originate from at least one zone of said medium, a step for analyzing the maximum correlation value as a function of the distance between the two elements whereby the correlated signals are received, said analysis step enabling the detection of the presence of a coherent reflector in said zone of said medium, and a step for labeling the zone in conformity with the result of the analysis step. The invention enables a binary image to be formed of a medium wherefrom noisy data originates, the binary values being attributed to the image as a function of the detection of a coherent reflector.

The invention relates to a controllable antenna structure (11) comprising a set of antennas (AA) arranged on a flexible support (12). Phase shifts and, in an advantageous embodiment, amplitude gains of electromagnetic current transmitted to these antennas (10), are determined by control means (13) to achieve a directive radiation pattern of the set of antennas (AA), said control means including computing means (18) which determine the radiation pattern of the set of antennas in accordance with global motion (GM) of the flexible support detected by tracking means (16), in accordance with local motion (LM) of the flexible support detected by detection means (17) and in accordance with the radio-frequency field characteristics (RF). Phase shifts and amplitude gains are transmitted to antennas via at least a phase shifter (14) and at least a gain multiplier (15).
