Abstract: A method and apparatus for selectably providing single-ended and differential signaling with controllable impedance and transition time is provided. According to the method and apparatus, a differential signal can be transmitted over two wires or two single-ended signals can be transmitted over the two wires. According to the method and apparatus, termination may be selected among a single-reference termination, a center termination, or a high-impedance termination. Regardless of the type of termination selected, a capability for dynamic control of the termination impedance is provided. Moreover, an ability to change impedances of termination elements to maintain a desired termination impedance for both single-reference termination and center termination modes by shifting bits is provided. Also, a capability for dynamic control of transition times of signals is provided.

Abstract: A circuit and method is shown for digital control of delay lines in a delay locked loop (DLL) system. A pair of multiplexors (MUXes) is used to select output taps from a pair of complementary delay lines that delay a reference clock signal in order to lock onto a received clock signal. An output tap from one delay line is used to produce a rising edge in an output clock signal while a corresponding tap in the complementary delay line is used to produce a falling edge in the output signal in order to correct for distortion. The MUXes are controlled based on a phase difference detected between the received clock signal and a feedback clock corresponding to the output clock signal. Another aspect of the present invention provides for generation of a quadrature clock by interpolating between the rising and falling edges selected for the output clock signal. Still another aspect of the present invention provides for selectively disabling unused elements of the delay lines to reduce power consumption.

Abstract: A system and method of terminating signals are described. In one embodiment, the termination system of the present invention comprises a receiver for receiving a signal from a transmission line, a termination node, a resistive element disposed between the receiver and the termination node, and a termination voltage controller for changing the voltage level of the termination node, in response to the detected signal voltage level. In another embodiment, the present invention includes a method of adaptively terminating a signal. The method of this embodiment comprises detecting the voltage level of a signal, selecting the termination voltage level of a termination node in response to the detected signal voltage level, and terminating the signal, through a resistive element, at the selected termination voltage level.

Abstract: A method for treating the surface of substantially each deagglomerated particle of an array of easily agglomerated particles by contacting deagglomerated particles with a plasma-activated gas species and modifying the surfaces of the deagglomerated particles to aid subsequent incorporation of the particles into a matrix composition; the module for deagglomerating and dispersing the particles into the plasma-activated gas; the apparatus that comprises the deagglomeration module (322) and a reaction chamber (20) in which the particles are treated with the plasma-activated gas; the method for deagglomerating particles that may reagglomerate after plasma treatment; and a color composition containing plasma-treated pigment particles.

Abstract: A photographic image holding sleeve (12) is adapted to be compatible with a multiple ring binder. The adaptor assembly (10) is a single sheet of mylar having a smooth surface (26) and an adhesive surface (24). The adhesive surface (24) is covered by a backing (32). The backing (32) is divided into two sections, the first section (34) being smaller than the second section (36). The first section (34) is removed so the adapter assembly (10) may be aligned properly and uniformly. The second section (36) is removed and the adapter assembly (10) is folded over itself (10) and the photographic image holding sleeve (12).
