Filed:

Jun 5, 2001

Appl. No.:

09/874582

Inventors:

Ronald J. Jaszczak - Chapel Hill NC
Paul Douglas Kirven - Durham NC
Timothy Warren Perry - Hillsborough NC

Assignee:

Data Spectrum Corporation - Hillsborough NC

International Classification:

G01M 1900

US Classification:

738664

Abstract:

A cardiac phantom is provided for simulating a dynamic cardiac ventricle. The phantom comprises two concentrically-disposed, fluid-tight, flexible membranes defining a closed space between the walls of the membranes. A pump is operatively connected to the inner membrane for reciprocally delivering a volume of fluid to the inner membrane to inflate and deflate both membranes in simulating systole and diastole of a heart. A medium is disposed within the closed space defined between the walls of the membranes for maintaining a uniform distance between the walls of the membranes during inflation and deflation. The phantom is provided for evaluation of medical imaging systems. A method, computer system and a computer-readable medium are also provided for controlling the phantom.

International Classification:

H04M 11/00

US Classification:

379 9301, 705 712

Abstract:

A method for providing confirmation of a request for a target communicated using text messaging includes receiving, by a sending system, a request for a target. The method further includes selecting, by the sending system, a telephone number from a list of telephone numbers, wherein a mapping is created between the request, the selected telephone number, the target, and a target contact. Additionally, the method includes sending, by the sending system to the target contact using the selected telephone number, a text message indicating the request for the target. Moreover, the method includes receiving a reply message from the target contact using the selected telephone number, and determining that the reply message comprises a reply to the request for the target by comparing the target contact and the selected telephone number for the reply message to the mapping.

Abstract:

A system and method that allows videoconferencing-formatted data to be viewed with standard media formats for computer systems. A processor interprets the header information contained in a videoconferencing-formatted data stream and reassembles the audio and video data into a standard media format. Although new headers are created, audio and video data are unmodified for the new format.

Abstract:

A curable composition including a reactive monomer or oligomer with acrylate functionality, an amine, and an alkyl peroxide. The alkyl peroxide is free or substantially free of phenyl rings. The alkyl peroxide can be dilauroyl peroxide (DLP). The curable composition can also include 3,5-diethyl-1,2-dihyrdro-1-phenyl-2-propylpyridine (PDHP). The curable composition can be provided as a two-part adhesive composition, including an A-side with DLP and an acrylic monomer, and a B-side with PDHP.
