Title: Degenerative load temperature correction for charge pumps
Inventor: BAINS RUPINDER
IPC: H02M3/07
Filed: 2001-09-25
Abstract: A regulator circuit to control the output of a charge pump circuit, to reduce the effects of operating temperature and process variations on available output current from the charge pump circuit. A predetermined fraction of the output voltage of the charge pump circuit is fed back to the input of a differential amplifier, which compares it to a reference voltage. The output of the differential amplifier feeds a voltage controlled oscillator (VCO), which in turn generates a clock signal that is used to drive the charge pump circuit. The normal temperature characteristics of this configuration cause the output of the charge pump circuit to degrade with temperature changes. The regulator circuit can be placed between the differential amplifier and the VCO to adjust the voltage driving the VCO. In one embodiment, a biasing resistor with a negative temperature coefficient can be used in the regulator circuit to offset the normal effects of temperature on the circuit. In another embodiment, multiple such resistors can be selectable with programmable logic, so that process variations during manufacture can be compensated for by selecting the resistor value that most closely provides optimal biasing.

Filed: 2001-07-30
Abstract: Procédé et appareil qui permettent la production d'un signal dont la fréquence de sortie est supérieure à la fréquence d'entrée. Un générateur de phases génère des signaux à phases multiples à partir du signal d'entrée, chaque signal de phase ayant la même fréquence que le signal d'entrée, mais étant en décalage de phase avec le signal d'entrée à raison de multiples d'un intervalle fixé. Ces signaux de phase sont transmis à un multiplexeur. La sortie du multiplexeur est déterminée par un mot de sélection généré par un accumulateur à partir d'une valeur se trouvant en mémoire. L'accumulateur est rythmé par la sortie du multiplexeur et l'accumulateur ajoute un mot de commande avec une valeur de réglage à la valeur se trouvant en mémoire dans l'accumulateur. L'addition est effectuée à chaque cycle de la sortie du multiplexeur. Le choix judicieux du mot de commande et de l'intervalle temporel entre les phases permet la génération à la sortie du multiplexeur de fréquences qui sont plus élevées que la fréquence d'entrée.

Title: Apparatus for producing layered tubes or rings
Inventor: RICHARDS DAVID C
IPC: B65B9/18
Filed: 1990-06-18
Abstract: An annular container mounted at the base of a passage between a layering tube and a central mandrel is charged with a layered tube of flexible tubing delivered over a floating mandrel when coaxially in contact with mandrel by driving rollers coacting with pinch rollers on the floating mandrel.  The tubing passes over the mandrel and gathers in the layering tube while being compacted by two sets of shoes reciprocated 180° out of phase by rotating discs and connecting rods. When sufficient tubing has been delivered the floating mandrel is raised to enable a hot wire to pass between the mandrels to sever the tubing.  The layering tube and central mandrel with the container can then be carried by a turntable through further stationary positions where the layered tubing is further compressed by reciprocable rings, a lid is put on the container to form a cassette and the cassette is discharged.
