Patent number: 9188673Abstract: An ultrasound imaging method transmits ultrasound into a medium from a source and receives and samples signals resulting from interaction of the ultrasound with the medium for each of a plurality of sources. The sampled signals are stored. Criteria are applied to select subsets of the stored sampled signals. In some embodiments the criteria relate to locations of a source and/or receiving element corresponding to a sampled signal. Images are generated from the subsets.Type: GrantFiled: August 7, 2012Date of Patent: November 17, 2015Assignee: InnerVision Medical Technologies Inc.Inventors: Bhaskar Ramamurthy, Timothy J. Davies

Patent number: 8234923Abstract: Systems and methods are disclosed for improving the resolution and quality of an image formed by signals from an array of receivers. Multiple receivers introduce variations in arrival times that can be less than the period of an operating signal, and also less than the period associated with a sampling operation. Thus, multiple receivers allow sampling of fine features of reflected signals that would be considered beyond the resolution associated with the operating signal. Use of multiple receivers also provides an effective sampling rate that is greater than the sampling rate of an individual receiver. Similar advantages can be obtained using multiple transmitters. Such advantageous features can be used to obtain high resolution images of objects in a medium in applications such as ultrasound imaging. Sub-Nyquist sampling is discussed. Accounting for the effects of refraction on pathlengths as a signal passes between two regions of different sound speed allows improved calculation of focus distances.Type: GrantFiled: November 19, 2010Date of Patent: August 7, 2012Assignee: InnerVision Medical Technologies Inc.Inventors: Bhaskar Ramamurthy, Timothy J.

Patent number: 5524681Abstract: An apparatus and method for filling and draining coolant from a battery cooling system (10). A coolant delivery system (94) is fluidly connected to the battery cooling system (10) for providing new coolant to the battery cooling system (10) when filling and for purging coolant from the battery cooling system (10) when draining. A pressurization system (96) is fluidly connected to the battery cooling system 10) for pressurizing the battery cooling system (10) after providing coolant when filling and for purging coolant when draining. A vacuum system (98) is fluidly connected to the coolant delivery system for creating a vacuum after draining to evacuate the battery cooling system (10) prior to filling. And, a controller (189) is electrically connected to the battery cooling system (10) to cycle a condenser fan (32) and coolant pump (26) coupled to the battery cooling system on and off according to a predetermined timing sequence.Type: GrantFiled: October 19, 1994Date of Patent: June 11, 1996Assignee: Ford Motor CompanyInventors: Timothy J.
