Abstract: A digitally controlled motor drive system using a pulse width modulated motor drive receives a desired motor velocity signal and an actual motor velocity signal and it provides a corresponding velocity error signal. The velocity error signal is adjusted in response to a change in the value of a power voltage supplied to the motor. The velocity error signal may be compensated for back electromotive force and/or for static friction in the motor, if desired. The system is simple, reliable and cost effective.

Abstract: In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described.

Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate having conductors is then laminated over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. The light sheets may be formed to emit light from opposite surfaces of the light sheet, enabling it to be used in a hanging fixture to illuminate the ceiling as well as the floor. The light sheet provides a practical substitute for a standard 2×4 foot fluorescent ceiling fixture.

Abstract: A device for separating metal components from a colloidal suspension or solution uses a vessel for holding the colloidal suspension or solution. A membrane impermeable to the selected metal components of a colloidal suspension or solution is sealed over a support to form a leaf element. The leaf element includes an outlet for the selected components of the colloidal suspension or solution and is extended into the colloidal suspension or solution. The leaf element is controllably vibrated simultaneously with application of a negative or positive pressure which is used to motivate permeation of the membrane by the liquid of the colloidal suspension or solution to purify it. Metals removed by the method include metals with an atomic number greater than 10 including and/or silicon. The colloidal suspension or solution may optionally contain a metal precipitator such as a dithiocarbamate and/or trithiocarbamate to aid in the separation.
