Patent number: 8928609Abstract: A touch sensitive display includes a capacitive touch sensor configured to output capacitance values. A motion sensor makes a motion detection and generates a motion signal including a motion value indicative of sensed motion detection. A touch detection circuit is coupled to receive the capacitance values and motion values. The touch detection circuit processes the capacitance values to make a hovering detection and a touching detection with respect to the display. The touch detection circuit further generates an output signal including the motion value correlated in time with each of the hovering detection and touching detection. The output signal may be processed as a user interface control signal. The output signal may also be processed to determine an impulsive strength of the touching detection as a function of an elapsed time between hover and touch and the measured motion values.Type: GrantFiled: July 9, 2012Date of Patent: January 6, 2015Assignees: STMicroelectronics International N.V., STMicroelectronics Asia Pacific Pte LtdInventors: Francesco Italia, Giuseppe Noviello, Chee Yu Ng, Benedetto Vigna

Patent number: 8174342Abstract: The invention relates to microelectromechanical systems (MEMS), and more particularly, to MEMS switches using magnetic actuation. The MEMS switch may be actuated with no internal power consumption. The switch is formed in an integrated solid state MEMS technology. The MEMS switch is micron and/or nanoscale, very reliable and accurate. The MEMS switch can be designed into various architectures, e.g., a cantilever architecture and torsion architecture. The torsion architecture is more efficient than a cantilever architecture.Type: GrantFiled: May 29, 2009Date of Patent: May 8, 2012Assignee: STMicroelectronics NVInventors: Tang Min, Liao Ebin, Giuseppe Noviello, Francesco Italia

Publication number: 20100328249Abstract: A touch screen uses a combination of capacitive sensing and inductive sensing applied to the same sensor pattern. A capacitive sensor uses the electric field formed by the columns and rows of the sensor matrix. An inductive sensor uses the magnetic field formed by current flowing in column and row lines to induce an inductive pen. Using the same sensor lines, the magnetic field created by the oscillating inductive pen is detected. Both methods require no moving elements in the sensor and it is possible to combine both method of detections in the same sensor pattern. Using switch matrices, the sensor lines are operated in an open loop fashion for the capacitive detection mode, and are operated in a closed loop fashion for the inductive detection mode.Type: ApplicationFiled: June 25, 2009Publication date: December 30, 2010Applicant: STMicroelecronics Asia Pacific Pte Ltd.Inventors: Kusuma Adi Ningrat, Giuseppe Noviello, Francesco Italia

Patent number: 7272511Abstract: Described herein are a molecular memory obtained using DNA strand molecular switches and carbon nanotubes, and a manufacturing method thereof. In particular, the nonvolatile memory is manufactured according to an architecture that envisages the use of carbon nanotubes as electrical connectors and DNA strands as physical means on which to write the information. In other words, the nonvolatile memory is made by means of a set of molecular DNA strand switches, the addressing of which is controlled by molecular wires made up of carbon nanotubes.Type: GrantFiled: June 19, 2003Date of Patent: September 18, 2007Assignee: STMicroelectronics, S.r.l.Inventors: Luigi Occhipinti, Francesco Buonocore, Vincenzo Vinciguerra, Gianguido Rizzotto, Giuseppe Panzera, Floriana San Biagio, Francesco Italia

Patent number: 6792111Abstract: A cryptation system for information transmitted through packet switching networks masks the digital information data by combining it at the transmitting station with digital data of a certain cryptation code before transmitting the so-encrypted data through the network. The system also performs an inverse decrypting processing at the receiving station using the same code. The system generates at a transmitting station and at a receiving station, starting from a given pair of password codes or user key, a certain discrete chaotic model or map of the pair of codes or key, producing dynamically updated pairs of values of codes or keys every certain number of processing steps of the chaotic map. The data to be transmitted is masked by way of a logic combination with the current dynamically updated keys at the transmitting station.Type: GrantFiled: October 12, 1999Date of Patent: September 14, 2004Assignee: STMicroelectronics S.r.l.Inventors: Francesco Italia, Luigi Fortuna, Francesco Beritelli, Eusebio Di Cola

Publication number: 20030219119Abstract: A method for generating a random number sequence whose randomness properties are determined a priori, includes defining a parametric map, calculating, in function of parameters of the map, the entropy and the Lyapunov exponent of random number sequences obtainable using the parametric map, and identifying at least a set of values of parameters for which the entropy and the Lyapunov exponent are positive numbers the map has no attracting point. The method further includes assigning a pre-established value as a first feedback value and cyclically carrying out the following steps for generating a random number sequence: determining the parameters inside the set as the numerical values of respective physical quantities, outputting a random number, according to the map with the parameters and the assigned feedback value, and assigning as new feedback value the output random number.Type: ApplicationFiled: December 13, 2002Publication date: November 27, 2003Applicant: STMicroelectronics S.r.l.Inventors: Ljupco Kocarev, Toni Stojanovski, Gianguido Rizzotto, Francesco Italia, Domenico Porto
