Title: A fractional-n divider using a delta-sigma modulator
Inventor: RILEY THOMAS A D
IPC: H03L7/197
Filed: 1999-03-30
Granted: 2003-03-11
Abstract: A delta-sigma modulator having a dead-zone quantizer and an error shaping digital filter clocked by a signal which is periodic at the frequency of the reference. A dead-zone quantizer provides quantization of a high resolution digital word to a low resolution digital word with three or a higher odd number of possible output levels and with an output of zero for an input near the centre of the normal input range. The delta-sigma modulator is used in a fractional-N divider. The fractional-N divider is used in a fractional-N frequency synthesizer.

En fonctionnement, chaque paire d'électrodes est stimulée à tour de rôle par l'application d'un courant connu. Pour chaque paire stimulée, une différence de potentiel obtenue est enregistrée au niveau de la paire d'électrodes restantes qui, quand elle est stimulée, produit un champ électrique dont les vecteurs sont les plus alignés possible avec les vecteurs du champ électrique produit par la paire d'électrodes stimulée.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for optimally determining sensor positions for an acoustic pyrometry, which is capable of obtaining a minimum number of sensors satisfying a given error limit on the basis of an effective independence method and determining positions of the obtained number of sensors suitable for error minimization. A predetermined number of sensors are arbitrarily arranged on sides of a rectangular sectional area to be measured and a transfer matrix is calculated with respect to positions of all the sensors. Then, effective independence values are obtained for respective paths of each of the sensors by performing singular value decomposition with respect to the calculated transfer matrix and a total effective independence value of each of the sensors is obtained by summing up the effective independence values obtained for the respective paths. Subsequently, one having a smallest one of the obtained total effective independence values is removed from among the sensors and the above steps are repeated until the number of the remaining sensors becomes equal to a target value. The target value is set to be larger than a minimum number of the sensors, which is found by calculating variations in a conditional number of the transfer matrix while the sensors are reduced in number and detecting a point where the conditional number increases abruptly.

Abstract: An apparatus and method for manufacturing a solid polymer film with a catalyst sufficiently deposited thereon preheats a solid polymer film and then hot presses this solid polymer film together with a catalyst carrier film. Hot pressing the solid polymer film while it is soft from preheating increases the bond strength between the solid polymer film and the catalyst such that separation of the catalyst from the solid polymer film during film separation can be prevented. Moreover, keeping the catalyst carrier film cool prior to hot pressing and making the temperature on the catalyst carrier film side slightly lower that than on the solid polymer film side during hot pressing inhibits an increase in binding strength between the film and the catalyst, and thereby improves separation of the film.

Title: Container sealing surface area inspection
Inventor: RINGLIEN JAMES A
IPC: G01N21/90

Granted: 2006-10-10
Abstract: Apparatus for inspecting the sealing surface area of a container finish that includes a light source positioned to direct a collimated line-shaped light beam (i.e., having a length dimension many times a width dimension) onto the sealing surface area of a container. The line-shaped light beam at the container sealing surface area has a long dimension orthogonal to the container axis, and a narrow dimension tangential to the container axis. A  light sensor is disposed to receive portions of the line-shaped light beam reflected from the sealing surface area, and provides an electrical output signal that varies with height or level of the sealing surface area with respect to the light source and sensor. A lens system is disposed to direct onto the light sensor only light energy reflected from the container sealing surface area in planes parallel to the common plane of the container axis and the sensor. The lens system and sensor together comprise a full imaging system for light energy reflected from the sealing surface in planes parallel to the common plane of the container axis and the sensor, but which is substantially immune from stray reflections, including reflections from other points on the container, that are not parallel to this plane.
