K partition said range within which all of said values fall, and providing a stream of numbers by randomly selecting numbers from a set S comprising the union of said sets of ni numbers, for i=1, . . .

Abstract: A technique that enables the sine and cosine branches within a PLL module to be obtained relatively easily and efficiently is described. According to the technique, the computation operations requiring a computation load, such as calculation of sine and cosine functions, are performed mostly once per a digital sampled signal, while relatively simple operations, such as multiplication and accumulations, are performed for every frame.

Abstract: A system for tracking and positioning a moving object, the system including a plurality of transmitters operative to transmit alternating electromagnetic fields within a three-dimensional space and at least one sensor arranged to be fixed to at least one corresponding portion of a moving object whose position it is sought to monitor. Each of said at least one sensors includes an electromagnetic field receiver having at least one active axis and operative to receive at least one component, lying along the at least one active axis respectively, of the alternating electromagnetic fields, an accelerometer to independently measure at least one component of the acceleration of the moving object; and a digital signal processor.

Abstract: A method for coherent detection and demodulation of a FDMA signal, that is a superposition of amplitude modulated carriers, is provided. An array of special digital phase-locked loops (PLLs) is implemented in a digital signal processor (DSP) for processing the received signal after it is digitized, and for extracting the envelopes corresponding to each carrier. Each PLL is deliberately made to slowly respond to error signals in order to allow the loop to preserve its phase while the amplitude value of the envelope flips sign. A down-decimation technique is employed in order to reduce the computational load. This is achieved by applying a finite impulse-response filter (FIR) only once per each frame, thereby only a single multiplication of the frame by the vector of filter's taps is employed. A digital generation of sine and cosine sampled waveforms is employed inside a PLL by using a real-time solution of a difference equation.

Abstract: A device, communicative with a PDA and comprising a movable part, that inputs to the PDA information about all or some of the six spatial variables of the movable part within a space that may be appreciably larger that the PDA and its display screen. The device may serve to conveniently input graphical and symbolic information, in place of a touch-screen, as well as to control multi-dimensional position and orientation of virtual objects in a natural analogous-motion manner. It may also be used in conjunction with an external passive keyboard to input alphanumeric information and commands.

Abstract: A method for reducing a current crosstalk interference component from an oscillating multiplex electric current flowing through a magnetic coil of a given electrical circuit originated from an electromagnetic flux emanating from a magnetic coil of a certain neighboring electrical circuit and intercepted by the magnetic coil of the given electrical circuit. The oscillating multiplex electric current has a main current component, related to the given electrical circuit, which is superposed with the current crosstalk interference component. The reduction of the crosstalk interference is achieved by estimating the current crosstalk interference component induced by the certain neighboring electrical circuit, and subtracting this current crosstalk interference component from a multiplex electric current flowing through the magnetic coil of the given electrical circuit by using earlier obtained crosstalk interference estimates.

Abstract: A three-dimensional position fixing system associated with the keyboard of a digital computer, the keyboard being provided with an array of passive keys which identify the numerals, letters, symbols and other values to be entered in binary code forms into the computer when the keys are touched by a finger of the operator. The system includes a responder mounted on the operator's finger and a transmitter-receiver assembly housed in the computer which cooperates with the responder to yield a signal indicative of the exact position of the finger when touching a particular key. Digitally stored in the data storage of the computer is a table listing the keyboard location of each key and the binary codes of the values identified by the keys.
