Abstract: The present invention provides a thermoplastic composition which may be unvulcanized or vulcanized. The thermoplastic composition can be a blend of a thermoplastic engineering resin, a halogenated terpolymer of a C4 to C7 isomonoolefin, a para-alkylstyrene, and a multiolefin. The engineering resin can be a polyamide, such as nylon 6/66 copolymers for example. The isomonoolefin can be an isobutylene for example. The multiolefin can be a C4 to C14 diene, such as isoprene for example.

Abstract: Methods and circuitry for implementing high speed first-in first-out (FIFO) structures. In one embodiment, a FIFO is disclosed that allows the frequency of one clock, e.g., the write clock, to be different than (e.g., half) that of the other (read) clock. In another embodiment a FIFO is presented that can be set and/or reset asynchronously. Other embodiments are disclosed wherein the read and write pointers are effectively monitored to ensure proper timing relationship, to detect loss of clock as well as to detect other abnormal FIFO conditions.

Abstract: An organic light-emitting diode (OLED) display is used in a system having a display controller that includes logic allowing a display area to be reduced from one size to a smaller size, according to one embodiment. The display area is reduced in response to a charge level of a battery decreasing to a predetermined level.

Abstract: Some embodiments of the present invention are directed to OLED materials useful in display devices and processes for making such OLED materials. The OLED materials may comprise polar compounds integrated with one or more substrates. When the polar compounds are simultaneously cured and exposed to an applied voltage or electric field, the polar compounds may be oriented in the direction of the voltage. Such orientation may result in the light emitted from the OLED material radiating in a single direction. Additional embodiments are directed to a system comprising a display device having a polar light-emitting layer whose dipoles are oriented in a single direction.

Abstract: Equalization is provided in a high speed communication receiver that includes in various aspects an automatic gain control input stage, a decision feedback equalizer, a clock and data recovery circuit and equalization control circuits. The automatic gain control stage may include a continuous time filter with an adjustable bandwidth. A threshold adjust signal may be applied to the output of the automatic gain control stage. The equalization control circuits may be implemented in the digital domain and operate at a lower clock speed than the data path.

Abstract: An equalization circuit adjusts (e.g., equalizes) an input signal according to the value of one or more adjustment signals (e.g., equalization coefficients) without a multiplication operation. For example, the circuit may add or subtract a value of a coefficient signal to the amplitude of an input signal. Here, whether the coefficient is added or subtracted may depend on the sign of a control signal.

Abstract: A compensation apparatus maintains an effective resistance of one or more resistors in a circuit by associating an adjustable resistor circuit to each resistor. The compensation apparatus compares the resistance of a resistor in the circuit with the resistance of a reference resistor. When the resistance of the resistor in the circuit falls outside of a desired range, the compensation apparatus adjusts the resistance of the adjustable resistor to adjust the effective resistance of the resistor and adjustable resistor combination.

Abstract: A coffee bean roaster and a method for roasting coffee beans using the roaster are disclosed. The coffee bean roaster includes an oven having a ceramic heating plate with a gate, and a rotary sliding unit to enter the gate so as to slide into the ceramic heating plate, so that the rotary sliding unit roasts coffee beans while rolling the coffee beans and spacing the coffee beans from both the ceramic heating plate and a burner. The method for roasting coffee beans using the coffee bean roaster includes entering the rotary sliding unit containing the coffee beans into the oven through the gate so as to place the rotary sliding unit in the oven at a position spaced apart from both the ceramic heating plate and the burner, roasting the coffee beans by far-infrared radiant heat emitted from the ceramic heating plate, and reburning combustion gases, generated from the roasting of the coffee beans, by the burner.

Abstract: A cholesteric display may be formed, in some embodiments, using a single display element to produce multi-colors for display. A cholesteric material may be sandwiched between a pair of substrates, each associated with pairs of opposed electrodes that are arranged in general transversely to the optical axis of incident light. The first pair of electrodes produce one of two liquid crystal states and result in the reflection of light of a particular wavelength. Light of other wavelengths may be reflected when a second pair (or set) of opposed electrodes, arranged in general transversely, also to the optical axis of incident light, are biased appropriately. So does a third pair (or set) of electrodes. A black and white color display may be generated from a single display element by modulating the pitch length of the cholesteric material within each pairs (or sets).
