IPC: H04W40/02
Filed: 2004-07-15
Abstract: Assignment of a session information IP address for use as a mobile station identifier facilitates a distributed architecture for processing IP  communications in coordination with a wireless communication system. The session information IP address identifies a storage location of session information for a given AT. The AT effectively carries a pointer to the session information, wherein an access point is able to access the session information directly. This avoids the need to store mapping information for each AT and associated location of session information. Additionally, use of an IP address identifying the session holder as a mobile station identifier avoid delays incurred by such mapping. The session information IP address may be compressed to use a locally unique value. The compressed version conserves bit space, and reduces processing complexity on relocation to a next access point.

Inventor: LEVINE PETER J
IPC: G16B50/00
Filed: 2004-12-10
Abstract: A model of a particular biological state can be developed. The model may be used to determine if an unknown biological sample exhibits a particular biological state. This can be done by receiving either a biological sample or data associated with the biological sample. After the data is received, the data may be input into the model. In one embodiment, the acquisition of the data associated with the biological sample is performed at a first location and the imputing of the data into the model is performed at a second location different than the first location. Unless the data maps identically to the model, the data would have an inherent effect on the position of the particular clusters within the discriminatory pattern, if it is allowed to affect the model. The modeling software can keep track of the net effect on the model that each sample received has on the position of the model. If the model has drifted outside of a predetermined tolerance, the model can be updated. Various business relationships may be developed to undertake various steps of the overall method for providing a diagnosis to a patient.

Abstract: A system and method for tissue differentiation. In the method, M acoustic signals si(t), i = 1 to M, are obtained from M locations on a body surface.  The N signals are subjected to band pass filtering using N band-pass filters, so as to generate NXM signals sij(t), i = 1 to M, j = 1 to N. K images I1 to IK, where K<N, are then generated using the signals sij(t), i = 1 to M, j = 1 to N. The pixels are divided into a predetermined number L of categories CL, from 1 to L, using the images I1 to IK. For each category CL, from 1 to L, and for each pixel p(x,y), a probability pL of assigning the pixel p(x,y) to the category CL is determined. An image may then be generated using the probabilities pL .
