Title: Capacitance measuring circuit for a capacitive sensor
Inventor: PRONOVOST JEAN
IPC: G01H11/06
Filed: 1998-12-15
Abstract: The circuit and the method are for measuring a capacitance of a capacitive sensor. According to the method, a charging circuit charges the capacitive sensor with a voltage and a discharging circuit discharges the capacitive sensor. A trigger circuit triggers the charging circuit and the discharging circuit in alternation into play as a potential of the capacitive sensor drops and rises to predetermined lower and upper levels respectively. An output circuit provides a signal having a low level during operation of one of the charging and discharging circuit and a high level during operation of theother one of the charging and discharging circuit. The signal has a period defined by a same level repetition which is indicative of the capacitance of thecapacitive sensor.

The piston assembly includes a piston and the cylinder assembly including a cylinder, there being a low clearance between the cylinder and the piston to enable a pumping action to be achieved without seals. Mounted on the exterior of the cylinder is a magnet and associated polepiece. Forming part of the cylinder assembly is a cylindrical housing in which the cylinder itself is mounted by means of a radially-extending flange. The coil for interaction with the magnet is positioned in an annular air gap between the polepiece and the housing.    The coil is wound on a coil holder which is itself mounted on the piston by way of a radially-extending flange. The other radial end of the coil holder is formed with radially extending wings which mount a cylindrical hub which is a clearance fit on the cylinder. The end of the coil holder is castellated to pass across the flange, through suitable apertures in flange. An AC current is applied to the coil to cause relative reciprocatory motion between the piston and cylinder to achieve a pumping action.

IPC: H03M7/36
Filed: 1998-08-26
Abstract: The invention relates to digital signal processing and specificly to level control of a pulse density modulated (PDM) signal generated by a sigma-delta modulator. A single-bit pulse density modulated PDM signal is generated by a first sigma-delta modulator (2) being an analog modulator, for instance. Level control is performed by multiplying the single-bit pulse density modulated PDM  signal by a multibit multiplier (300) to obtain a multibit number stream, which is reconverted into a single-bit PDM signal by a second digital sigma-delta modulator (4). In accordance with the invention, the performance of the second sigma-delta modulator (4) is better than that of the first sigma-delta modulator (2), as to the signal-to-noise ratio. Thus, the most significant factor in the total signal-to-noise ratio (SNR) is the noise level of the first sigma-delta modulator (2), by which the PDM signal was originally generated. In the subsequent second sigma-delta modulator (4), the PDM signal can then be attenuated as much as is the difference between the SNR  performances of the modulators without any decrease in the total signal-to-noise ratio. A relative amplification of the PDM signal is provided in this manner.

Title: In-line cable tie
Inventor: WELLS PETER M
IPC: F16L3/233
Filed: 1998-03-25
Abstract: A cable tie includes an elongate generally planar strap and a head. The head includes a tapering entrance into a passageway therethrough for inserting the strap and a flexibly hinged locking pawl adjacent the passageway. The head also includes a fixed locking tooth adjacent the entry end of the passageway for engaging the strap after fully securing an article or articles to be bundled. The fixed locking tooth of the present invention is desirably positioned to allow unobstructed insertion of the tail through the head. The present invention is able to minimize the stretching of the strap body when adjacent to the locking pawl by providing an edge which fractionally engages the strap body as the strap body egresses from the passageway of the head. Furthermore, the present invention may include a pair of counter-rotatable locking elements positioned to one side of the passageway through the head. One of the counter-rotatable locking elements may deflect into engagement with a surface of an article being bundled so as to provide greater slip resistance of the cable tie with respect to the article and to further allow an even smaller bundling radius for the cable tie. Additionally, the present invention provides a cable tie having a tamper-resistant locking pawl. Furhtermore, the cable tie of the present invention may include a deflectable locking element which may be integrally formed with the head or separately provided within the head.
