Patent number: 8494871Abstract: A medical apparatus (901, 100) assists clinicians, nurses or other users in choosing an intervention for the treatment of a patent suffering from an acute dynamic disease, e.g. sepsis. The medical apparatus is based on a method where a model of the disease is adapted or personalized to the patient. To ensure that the apparatus remains capable of predicting the health of the patient, the apparatus is continuously provided with new, more recent patient values and the model is continuously adapted to the new patient values. Since the medical apparatus is configured to be continuously adapted to current state of health, the apparatus is able to assist the user by generating disease management information, e.g. suggestions for medications, to an output device (902, 104).Type: GrantFiled: July 11, 2008Date of Patent: July 23, 2013Assignee: Koninklijke Philips N.V.Inventors: James David Schaffer, Mark R.

Patent number: 8208697Abstract: A method for determining the presence or absence of malignant features in medical images, wherein a plurality of base comparison or training images of various types of lesions taken of actual patient is examined by one or more image reading experts to create a first database array. Low-level features of each of the lesions in the same plurality of base comparisons or training images are determined using one or more image processing algorithms to obtain a second database array set. The first and second database array set are combined to create a training database array set which is input to a learning system that discovers/learns a classifier that maps from a subset of the low-level features to the expert's evaluation in the first database array set. The classifier is used to determine the presence of a particular mid-level feature in an image of lesion in a patient based solely on the image.Type: GrantFiled: December 13, 2005Date of Patent: June 26, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: James David Schaffer, Walid Ali, Larry J.

Publication number: 20080195570Abstract: A system and method for collecting evidence pertaining to relationships between biomolecules and a disease, or other clinical condition, wherein biomolecules associated with the disease or condition identified, and ontologies relating to the biomolecules, disease or condition, and a predicate relationship therebetween are generated (or input to a processing system). Triplets, subject/predicate/object, for example, biomolecule/relationship/disease, are constructed by processing the ontologies. The triplets are used to search a body of relevant evidence to extract pertinent data from the body of relevant data based on the triplets. The system and method of the invention is used to provide researchers in the field of molecular diagnostics with biological evidence for or against statistical predictions.Type: ApplicationFiled: March 27, 2006Publication date: August 14, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Yasser H.

Patent number: 6990635Abstract: A user interface for a TV recommender system includes a display screen having a first region for displaying a rating derived from a previously defined TV viewing preference profile contained in the recommender system; and a second region displaying preference settings in the profile which were used to derive the rating. The user interface enables the preference settings to be changed if the rating derived by the profile is incorrect. Additionally, the user interface allows for new features to be added to the profile, which were not previously a part of the profile.Type: GrantFiled: January 24, 2001Date of Patent: January 24, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Kaushal Kurapati, James David Schaffer

Publication number: 20040010480Abstract: A method for operating a neural network, and a program and apparatus that operate in accordance with the method. The method comprises the steps of applying data indicative of predetermined content, derived from an electronic signal including a representation of the predetermined content, to an input of at least one neural network, to cause the at least one network to generate at least one output indicative of either a detection or a non-detection of the predetermined content. Each neural network has an architecture specified by at least one corresponding parameter. The method also comprises a step of evolving the at least one parameter to modify the architecture of the at least one neural network, based on the at least one output, to increase an accuracy at which that at least one neural network detects the predetermined content indicated by the data.Type: ApplicationFiled: July 9, 2002Publication date: January 15, 2004Inventors: Lalitha Agnihotri, James David Schaffer, Nevenka Dimitrova, Thomas McGee, Sylvie Jeannin

Publication number: 20030145326Abstract: A system and method for subscribing TV programs according to the preferences of the user based on the user's past viewing history. The system keeps track of all the programs watched by the user to generate a profile indicative of the frequency of a particular program being watched. Then, a plurality of subscription plans based on the viewer's viewing habit stored in the user profile is offered to the user, so that the user can selectively pay for the programs of his or her interest, instead of paying for the entire programs.Type: ApplicationFiled: January 31, 2002Publication date: July 31, 2003Applicant: Koninklijke Philips Electronics N.V.Inventors: Srinivas Gutta, James David Schaffer, Larry James Eshelman

Publication number: 20020116710Abstract: A TV viewer profile initializer for reducing the time it takes for an implicit profiler-based TV recommender to produce accurate TV recommendations. The profiles initializer utilizes stereotype profiles from a substantial pool of TV viewing behavior of a representative number of TV viewers. By applying clustering methods to such data, stereotype profiles can emerge. New viewers are then be offered a selection of stereotype profiles to choose from to initialize their own personal TV viewing profile. Thus, a single choice will suffice to provide a predictable TV show recommender that is presumably fairly close to a viewer's own preferences. After this initialization, the profile can be adapted by the user's own viewing behavior to migrate from the initial stereotype towards a more accurate profile of the user.Type: ApplicationFiled: February 22, 2001Publication date: August 22, 2002Inventors: James David Schaffer, Paul John Rankin, Keith Mathias, John Milanski
