Abstract: Systems and methods relating to the provision of gain, phase and delay adjustments to signals to be used by a predistortion subsystem. A portion of an input signal is delayed by delay elements prior to being received by the predistortion subsystem. The delayed input signal portion is also received by a feedback signal processing subsystem that adjusts the gain and phase of the feedback signal based on the delayed input signal portion. The adjusted feedback signal is used, along with the delayed portion of the input signal, to determine an appropriate predistortion modification to be applied to the input signal.

The first electrode includes at least one non-smooth surface and is formed from a material selected from the group consisting of transition metals, conductive oxides, alloys thereof, and combinations thereof. The method further includes forming a dielectric on the first electrode and an uppermost surface of the substrate assembly, and forming a second electrode on the dielectric and the uppermost surface of the substrate assembly. The second electrode includes at least one non-smooth surface.
Abstract: Systems, methods, and devices relating to the provision of deliberate predistortion to an input signal to compensate for distortions introduced by an amplifier subsystem. An input signal is received by a signal processing system which includes a predistortion subsystem. The input signal is decomposed and the fragments are then predistorted by the predistortion subsystem by applying a deliberate predistortion to the fragments. The predistorted fragments are then separately processed and recombined to arrive at the system output signal. The predistortion subsystem adaptively adjusts based on characteristics of the system output signal. Also, the predistortion subsystem is equipped with a control system that is state based—the state of the predistortion subsystem is dependent upon the prevailing conditions and, when required, the control system switches the state of the predistortion subsystem.
Abstract: A system and method for servoing on a moving target within a dynamic scene. According to one embodiment, the system includes a master variable pointing camera system and a plurality of slave variable pointing camera systems positioned around the scene. The system also includes a master control unit in communication with the master variable pointing camera system. The master control unit is for determining, based on parameters of the master variable pointing camera system, parameters for each of the slave variable pointing camera systems such that, at a point in time, the master variable pointing camera system and the slave variable pointing camera systems are aimed at the target and a size of the target in an image from each of the master variable pointing camera system and the slave variable pointing camera systems is substantially the same. The system also includes a plurality of slave camera control units in communication with the master control unit.

Abstract: The invention relates to a method for controlling the temperature in a controlled-climate chamber, wherein: an organism, such as a plant or an animal, is placed in the controlled-climate chamber; the temperature in the controlled-climate chamber is kept essentially constant at a specific value (T1); at least one growth characteristic (G) of the organism, such as, for example, the CO2 production, is measured; the temperature in the controlled-climate chamber is raised or lowered by a specific value (?T); the magnitude of the growth characteristic is measured again; the variation in the measured value of the growth characteristic is determined (?G); and the temperature in the controlled-climate chamber is adjusted, depending on the variation in the measured value of the growth characteristic (?G) that has been determined.
Abstract: A method of placing a component having leads and an alignment indicating fiducial marker is provided. The method includes detecting the alignment of the fiducial marker on the component, comparing the detected fiducial alignment with a predetermined fiducial alignment and placing the component to a substrate when the detected fiducial alignment corresponds to the predetermined fiducial/alignment.
Abstract: Precipitation of polyacetylenic agents can be effected with control of a particle size parameter such as mean size or spread, by mixing a warm solution of the acetylenic agent with a cold precipitation fluid and appropriate selection of a constituent of the cold precipitation fluid and/or of the temperature conditions and collecting the precipitated acetylenic agent. Precipitation additives such as nitrocellulose or gelatin can usefully be employed. Solvents such as aqueous methanol and ethyl 3-ethoxypropionate can be useful. Polyacetylenic agents, e.g. substituted diacetylenics are useful to provide visual changes in condition-monitoring indicators such as time-temperature indicators, “TTIs”, useful as freshness indicators for radiation exposure monitoring and for other purposes. Controlled, small and/or consistent particle sizes of such polyacetylenic agents are helpful in providing consistent commercial properties, especially in inks in which they may be formulated.
