US Patent:

20140058266, Feb 27, 2014

Filed:

Aug 20, 2013

Appl. No.:

13/971689

Inventors:

Josef R. Call - Campbell CA, US
Kenneth D. Brewer - Santa Clara CA, US
Viet Nam Le - San Jose CA, US
Matthew Ouellette - Menlo Park CA, US
Mathias Blake - Madison WI, US

International Classification:

A61B 8/14

US Classification:

600448, 600443

Abstract:

A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.

International Classification:

B64B 1/12
B64B 1/08

Abstract:

In an embodiment, a system for synchronizing the rotation of multiple mainframes of an airship includes multiple belt drive systems configured to mechanically rotate the mainframes, a central control system for sending a timing instruction to cause the mainframes to rotate synchronously about their respective rotational axis, wherein the mainframes are axis-aligned about their respective rotational axes and the timing instruction specifies a desired angular displacement of the mainframes, and multiple control units for controlling the belt drive systems to rotate the mainframes, respectively, wherein, for each mainframe, the associated control unit is configured to: receive the timing instruction from the central control system; determine, according to the timing instruction, a rotation instruction based on a size of the mainframe and the desired angular displacement; and instruct the belt drive system controlled by the control unit to rotate the mainframe based on the rotation instruction.

International Classification:

B64B 1/08

Abstract:

A jig for constructing a mainframe of an airship structure, including multiple tracks configured in a radial pattern, each track including rails that are configured to be parallel to each other, multiple front carts for securing inner portions of the mainframe corresponding to an inner circumference of the mainframe, each front cart configured to be positionally adjustable along one of the tracks, and multiple back carts for securing outer portions of the mainframe corresponding to an outer circumference of the mainframe, each back cart configured to be positionally adjustable along one of the tracks.

International Classification:

A61B 8/08
A61B 8/00
G01S 15/89

Abstract:

A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.
