el Physiological data acquisition and management system for use with an implanted wireless sensor By www.freepatentsonline.com Published On :: Tue, 07 Feb 2012 08:00:00 EST Aspects and embodiments of the present invention provide a system for obtaining, processing and managing data from an implanted sensor. In some embodiments, a patient or other persons can use a flexible antenna to obtain data from the implanted sensor. The flexible antenna includes at least one transmit loop and at least one receive loop. The transmit loop is adapted to propagate energizing signals to the implanted sensor. The receive loop is adapted to detect a response signal from the implanted sensor. The transmit loop includes a capacitor formed by a discontinuous area. The capacitor is adapted to allow the loop to be tuned. The flexible antenna can communicate with a patient device that collects the data from the implanted sensor, creates a data file and transmits the data file to a remote server over a network. A physician or other authorized person may access the remote server using an access device. Full Article
el Memory cell based array of tuning circuit By www.freepatentsonline.com Published On :: Tue, 26 Jun 2012 08:00:00 EDT A method applied in a tuning circuit comprising a plurality of turning cells is disclosed. the method comprises: laying out a array of tuning cells in a matrix configuration, the matrix comprising a first dimension and a second dimension; assigning a first index associated with the first dimension and a second index associated with the second dimension to each tuning cell; controlling each tuning cell using a word line and a bit line; and summing up outputs from all tuning cells to form a combined output. The tuning cell provides a first circuit value or a second circuit value according to the logical value of the bit line, and the difference between the first circuit value and the second circuit value is determined such that a turning resolution of the tuning circuit is determined.

el Electromagnetic system with no mutual inductance and an inductive gain By www.freepatentsonline.com Published On :: Tue, 23 Apr 2013 08:00:00 EDT An electromagnetic system consists of an electric circuit comprising two solenoids wired in series, one mounted either side and proximate to a toroid. Voltage is applied across the toroid and the solenoids in a specific sequence which alters the inductance behavior of the system, resulting in an inductance gain and no mutual inductance between the toroid and the two solenoids.
