Abstract: Apparatus, including a set of N electrodes (22), configured to be located in proximity to an epidermis (24) of a subject, and to acquire signals generated by electric sources within the subject. The apparatus also includes a set of M channels, configured to transfer the signals, where M is less than N, and a switch (40), configured to select, repetitively and randomly, M signals from the N electrodes and to direct the M signals to the M channels. The apparatus further includes a processor (28), configured to activate the switch, and to receive and analyze the M signals from the M channels so as to determine respective positions of the electric sources within the subject.

Abstract: A method of processing an image is disclosed. The method comprises decomposing the image into a plurality of channels, each being characterized by a different depth-of-field, and accessing a computer readable medium storing an in-focus dictionary defined over a plurality of dictionary atoms, and an out-of-focus dictionary defined over a plurality of sets of dictionary atoms, each set corresponding to a different out-of-focus condition. The method also comprises computing one or more sparse representations of the decomposed image over the dictionaries.

Abstract: A diagnostic system includes an array of electrodes, which are coupled to a body surface of a living subject at different, respective positions in proximity to a region of interest within the body. A switched impedance network applies varying loads to the electrodes. A processor is coupled to receive and measure electrical signals from the electrodes as a function of the varying loads, and to analyze the measured signals so as to compute a local electrical characteristic of one or more locations within the region of interest.

Abstract: A diagnostic method includes applying a vibration at a selected frequency to a location within a brain of a living subject (32). Electrical signals resulting from the vibration are measured at multiple positions on a scalp of the subject. The measured electrical signals are processed in order to compute an electrical gain matrix between the location within the brain and the positions on the scalp. Electroencephalogram (EEG) signals are measured at the multiple positions on the scalp. The EEG signals are filtered using the gain matrix in order to identify brain electrical activity originating from the location.

Abstract: A method for image reconstruction includes defining a dictionary including a set of atoms selected such that patches of natural images can be represented as linear combinations of the atoms. A binary input image, including a single bit of input image data per input pixel, is captured using an image sensor. A maximum-likelihood (ML) estimator is applied, subject to a sparse synthesis prior derived from the dictionary, to the input image data so as to reconstruct an output image comprising multiple bits per output pixel of output image data.
