Abstract:
A switched capacitor circuit includes a threshold detector to generate a threshold detection signal when a difference between first and second input signals crosses a predetermined level. A variable current source produces a varying amount of current in response to the difference between the input signals. A voltage measurement means produce a measurement signal in response to the difference between the input signals. A correction means produces a correction signal in response to the measurement signal to produce an optimum coarse phase overshoot. A timing comparison means produces a timing signal in response to the difference between the input signals. A correction means produces a correction signal in response to the timing signal to produce an optimum coarse phase overshoot.
Abstract:
Disclosed is a curable silicone composition for preparing release layers and pressure sensitive adhesives, and to substrates bearing a layer of the cured composition. More specifically, this invention relates to a silicone composition, curable in the absence of both catalysts and actinic radiation comprising a cyclic anhydride copolymer and an amine-terminated polysiloxane.
Abstract:
The disclose provides pressure-sensitive adhesives and adhesive sealants prepared from modified, crosslinked isobutylene copolymers, and tape articles prepared therefrom.
Abstract:
Disclosed are copolymers which comprise: a) an isobutylene copolymer having grafted polymer groups, b) optionally a tackifier, and c) optionally a non-functionalized poly(isobutylene) polymer. The compositions are useful in adhesives and coatings.

Abstract:
A circuit includes a level-crossing detector to generate a level-crossing detection signal when an input signal crosses a predetermined voltage level. A first stage set of capacitors is operatively coupled to the level-crossing detector. A ramp circuit is operatively coupled to the set of series-connected capacitors. A second stage set of capacitors is operatively coupled to the first stage set of capacitors and the ramp circuit. The ramp circuit includes a feedback capacitor and a preset switch to provide a linear ramp output.
