Publication number: 20140365324Abstract: The invention discloses a method and system for exchanging data between users using a transaction phrase, comprising: composing a data package by a source, uploading the data package onto a server, receiving a transaction phrase associated solely with the data package generated from a dictionary database utilized by the server, communicating the transaction phrase by the source to a recipient, requesting the data package by the recipient using the phrase, and receiving the data package from the server to the recipient if the parameters allow. The invention also details a financial aspect wherein a payment dialogue is initiated on the recipient interface allowing the recipient to complete a payment through a merchant server. Another embodiment comprises receiving a payment by the recipient upon submitting the transaction phrase to the server. The invention also envisions allowing the source to create a source account before composing the data package.Type: ApplicationFiled: April 15, 2014Publication date: December 11, 2014Applicant: RARE CORPORATIONInventors: Christopher J.

Publication number: 20140316273Abstract: A method of detecting liquid in animal tissue is disclosed. The method comprises providing an electromagnetic radiation generator, and applying electromagnetic radiation to a tissue region using the electromagnetic radiation generator. The characteristics of the electromagnetic radiation are selected so as to cause differential heating in a tissue region based on liquid content in the tissue region, differential expansion of matter in the tissue region, and thereby generation of ultrasound signals that vary according to the liquid content. The method also comprises providing an ultrasound detector, detecting the ultrasound signals using the ultrasound detector, and using the detected ultrasound signals to produce an indication of concentration of liquid in the tissue region and a determination as to whether a change in liquid concentration in the tissue region has occurred.Type: ApplicationFiled: June 11, 2012Publication date: October 23, 2014Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventors: Robert Kery, John Gal, Christopher J Rothfuss

Publication number: 20140249391Abstract: Methods for distinguishing between two interspersed biological tissues, for procedures such as surgical resection, include exposing the tissues to at least two components, a first of which components produces or is capable of producing a detectable signal, and the other of which components either blocks the produced signal of the first component or activates the first component to produce the detectable signal. One of the components is selectively taken up by one of the tissues at a concentration which is greater than the concentration by which it is taken up by the other tissue to provide a distinguishable difference in the detectable signal originating from the two tissues.Type: ApplicationFiled: April 23, 2012Publication date: September 4, 2014Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventor: Christopher J. Rothfuss

Publication number: 20130276885Abstract: Separation layers, usable in devices for converting radiation energy to electrical energy, allow at least some of the components of the devices to be separated from one another for disposal thereof. A separation layer may be interposed between and bonded to adjoining layers, and when acted upon by application of an external source, may be degraded to release the layers from one another. Once released, the layers may be disposed of more efficiently and economically, including proper disposal of hazardous waste, and recycling of materials which may be re-usable.Type: ApplicationFiled: April 23, 2012Publication date: October 24, 2013Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventors: Sung-Wei Chen, Christopher J.
