Abstract:
A pressure sensor is for positioning within a structure. The pressure sensor may include a pressure sensor integrated circuit (IC) having a pressure sensor circuit responsive to bending, and a transceiver circuit coupled to the pressure sensor circuit. The pressure sensor may include a support body having a recess therein coupled to the pressure sensor IC so that the pressure sensor IC bends into the recess when the pressure sensor IC is subjected to external pressure.
Abstract:
The integrated electronic device is for detecting a local parameter related to a force experienced in a predetermined direction within a solid structure. The device includes a semiconductor substrate having a substantially planar region that defines a plane substantially perpendicular to the predetermined direction. At least one sensor detects the local parameter at least in the predetermined direction with a piezo-resistive effect. At least one substantially planar face is arranged in a portion of the integrated electronic device, the face belonging to a inclined plane by a predetermined angle relative to the plane perpendicular to the predetermined direction, which plane is defined by the substantially planar region of the substrate. The predetermined angle is defined such as to reduce forces acting in directions other than the predetermined direction at the portion of the device around the at least one sensor.
Abstract:
The method is for protecting the digital contents of a solid state memory including a microprocessor. A microprocessor inserts at least an interruption during a copy or a reading of the digital contents and proceeds with the copy or reading only subsequently to a verification of a PIN. In particular, the verification provides control that the PIN is inserted manually. Also, a solid state memory includes a microprocessor programmed for inserting at least an interruption in a copy or reading of digital contents of the memory, for verifying a PIN, and for proceeding with the copy or the reading, if the PIN is inserted correctly.
Abstract:
A system provides two distinct solutions for encoding and decoding servo positioning data for a hard disk drive. A first solution includes: encoding each group of four bits of a pattern signal in a Matched Spectral Null (MSN) format through an intermediate rate 4/6 code; providing a duplicated bit for each bit of the six bit code word obtained with the previous step. A second solution includes: encoding each group of four bit of the pattern signal adding a parity check bit as an intermediate rate ⅘ code; encoding each of the five bits using the biphase map. Both solutions include subsequently: reading a servo wedge information signal using a read and write channel of the hard disk drive; and using a trellis Partial Response decoding scheme matched to the encoded word for obtaining angular and radial information for the head positioning.

Moreover the use of the compound for detecting nucleic acids, a process for its synthesis, and a system comprising the same are described.
Abstract:
A CMOS elementary cell of the first order for time-continuous analog filters with non-linearity compensation, is connected between a first supply voltage reference and a second voltage reference. The cell is of a type which comprises at least a first MOS transistor having its conduction terminals connected to the first supply voltage reference and to an output terminal, and having a control terminal connected to an input terminal of the first order CMOS elementary cell. The cell further comprises a second MOS transistor in diode configuration, and an equivalent capacitor, both connected to the output terminal of the first order CMOS elementary cell. The second, diode-connected MOS transistor and the equivalent capacitor act as a load for the first MOS transistor. The first MOS transistor operates as a drive transistor operatively tied to an input voltage signal being supplied to the input terminal of the first order CMOS elementary cell. A second order filter CMOS elementary cell is similarly connected.
Abstract:
A circuit generates a regulated voltage, in particular for gate terminals of non-volatile memory cells of the floating gate type. The circuit includes a generator circuit adapted to generate an unregulated voltage on its output. A comparator circuit is coupled to the output of the generator circuit including a reference element including a non-volatile memory cell of the floating gate type and adapted to output an error signal tied to the difference between the unregulated voltage and the threshold voltage of the cell. A regulator circuit is coupled to the output of the comparator circuit and is operative to regulate the unregulated voltage based on the value of the error signal. The regulated voltage is made programmable and tied to the parameters of the memory cell.

Abstract:
An embodiment of a simulation tool includes a path determiner and a simulator. The path determiner is configured to identify a first communication path between first and second devices of a system, and the simulator is configured to simulate a routing of a first item from one of the first and second devices to the other of the first and second devices via the identified path. The path determiner may also be configured to identify the communication path before the simulator simulates the routing of the item, or to identify the communication path while the simulator is inactive.
