Publication number: 20160041998Abstract: Computer systems and methods providing personalized delivery of video files to a user's device. A computer server allows a user to create a user profile which includes information about certain user preferences, such as a favorite subject matter, favorite participant(s) and the like and, when a user connects to the computer server, the server checks a video database for video files of potential interest to the user and generates a ranking of video files of potential interest, then provides information and, if requested, the video files, to the user in order of the ranking. The ranking may be based on a variety of inputs, including both express and/or implied user preferences, the elapsed time between the publication (or creation) of a video file and the user's request therefor, the subject matter of the video file, the teams, players, and other persons included in the video file, the length of the video file, and a variety of other information about the video file.Type: ApplicationFiled: August 5, 2014Publication date: February 11, 2016Inventors: Christopher S.

Patent number: 8357112Abstract: This invention relates to a method and an apparatus of controlling a release of a material carried by ultrasound sensitive particles, the release being caused by irradiating the ultrasound sensitive particles with an ultrasonic pulse having acoustic properties selected so as to interact with the ultrasound sensitive particles and thus causing the release of the material. The ultrasound sensitive particles comprise sub-groups of ultrasound sensitive particles, the ultrasound sensitive particles within the same sub-group having their respective acoustic property causing each respective sub-group to interact independently with the sound wave.Type: GrantFiled: March 3, 2008Date of Patent: January 22, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Nevenka Dimitrova, Christopher S.

Patent number: 7957219Abstract: An acoustic probe includes an acoustic transducer having acoustic transducer elements arranged in a one-dimensional array; and a variably-refracting acoustic lens coupled to the acoustic transducer. The variably-refracting acoustic lens has a pair of electrodes configured to adjust the focus of the variably-refracting acoustic lens in response to a selected voltage applied across the electrodes. In one embodiment, the variably-refracting acoustic lens includes a cavity, first and second fluid media disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.Type: GrantFiled: April 27, 2007Date of Patent: June 7, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Christopher S.

Publication number: 20110130663Abstract: A phased ultrasound array for an ultrasound generating device. In one embodiment, the array includes a plurality of ultrasound elements arranged symmetrically about a point or dividing line in the array with respect to element size, shape and/or element location. In another embodiment, a majority of larger elements of the ultrasound array are arranged on a first portion of the array and a majority of smaller ultrasound elements are arranged on a second portion of the array. The first portion is closer to a preferred direction of steering than the second portion. Another method includes selecting randomly sized ultrasound elements and arranging the ultrasound elements symmetrically on the array. An additional method includes selecting randomly sized ultrasound elements and arranging the ultrasound elements wherein the larger ultrasound elements are arranged on a first portion of the array and smaller ultrasound elements are arranged on a second portion of the array.Type: ApplicationFiled: October 19, 2007Publication date: June 2, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Balasundara Raju, Christopher S.

Publication number: 20110125080Abstract: Described is a method for the delivery of a therapeutic agent to a mammal, particularly a human person, comprising (i) the administration of ultrasound particles that undergo a physical change when subjected to ultrasound; (ii) the administration of the therapeutic agent in an ultrasound dosage form allowing release of the therapeutic agent to be affected by the application of ultrasound, (iii) the application of ultrasound so as to affect a physical change in at least some of the ultrasound particles, and (iv) the application of ultrasound so as to stimulate release of the therapeutic agent. According to the invention the ultrasound particles are subjected to detection of their acoustic responses via echoes and/or emissions. The information thus obtained is processed and the processed information is used to adapt or adjust the ultrasound-mediated delivery of the therapeutic agent.Type: ApplicationFiled: June 9, 2009Publication date: May 26, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: William Tao Shi, Chien Ting Chin, Christopher S.
