    Abstract: A voltage converter provides a desired voltage droop with load while avoiding output current sensing and active control/feedback circuits and avoiding excessive power dissipation from passive components by placing a sensing resistor in the low current, switched input circuit of the voltage converter. Therefore, the resistor conducts only when a switch controlling voltage conversion is conductive, generally at very low duty cycle and low current.

    Abstract: A rotor with wedges and a method of retaining wedges in a rotor are disclosed. The rotor includes a shaft, first and second poles extending radially from the shaft, and first and second coils of windings respectively wrapped around the first and second poles. Each coil includes a respective outer face including two end portions and two side portions, and a respective inward-facing edge including two end sections and two side sections. The rotor further includes a first outer wedge positioned between neighboring side portions of the first and second coils, and a first inner wedge positioned between neighboring side sections of the first and second coils. The first inner wedge is coupled to the first outer wedge so that the first outer wedge is at least partly retained from moving radially outward away from the shaft.

    Abstract: The present invention discloses an optical switching element that uses reversible electroplating mirrors includes a trench with transparent sidewalls located at the intersection of two waveguides A and B. The trench has two electrodes; one, which is transparent, is placed on the trench sidewall and the other is placed on the trench floor. The trench is filled with an index-matching electrolytic solution containing ions of a metal that can electro-deposit on these two electrodes. To actuate the switching element, a negative electrical potential is applied to the sidewall electrode. Actuation causes metal deposits to form on the sidewall electrode, creating a mirror that reflects light from waveguide A to waveguide B. To deactivate the switching element, a positive electrical potential is applied to the sidewall electrode. Deactivation causes metal deposits move off the sidewall and form on the trench floor. The lack of metal deposits on the sidewall allows light to pass through the switching element and continue along the original waveguide A

    Abstract: A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents. The energy-activated components have multiple functional groups that react with active hydrogen, components that contain active hydrogen, or components that are capable of conversion to active hydrogen containing groups.
