A portable remote wireless control for establishing different temperatures in separate portions of a building. The remote control not only regulates hot and cold airflow through rotatable damper vanes in one or more diffusers, but it also recharges the batteries that power the wireless receiver, servomotor and servomotor controls that selectively rotate the damper vanes. Damper vane rotation regulates air flow from the diffuser to control the temperature in the portion of the building. The damper vanes, moreover, are of a light plastic with a marginal band of a foam material to enable the vanes to rotate silently and freely also to form a seal that eliminates a great deal of air seepage past the individual vanes.

A method for overcoming the drawback in a fiber CPA laser system that includes a process of generating a large negative TOD by implementing an AODS in a pulse shaper as a dispersive component. The AODS is implemented to arbitrarily modulate both the spectrum shape and phase to control with controllable amplitude to generate different orders of dispersions including a large negative TOD for compensating the positive TOD generated by the pulse stretching and amplification processes. The AODS, implemented as a dispersive component, can be an active and controllable dispersive component to generate adjustable levels of dispersions for flexibly compensating any order of dispersions generated in the amplifier chain including the nonlinear phase shift.

An adjustment amount of a brightness level is determined for each pixel of an image based on the value of each pixel of a luminance distribution image which represents the distribution of luminance of the image. A portion contributing to adjustment of brightness and a portion contributing to adjustment of saturation are determined for each pixel of the image so that the sum thereof is equal to the adjustment amount of the brightness level. Then, an adjustment value of saturation, which is obtained by weighting the value of each pixel in the image based on the portion contributing to saturation, and an adjustment value of brightness, which is obtained by weighting the value of each pixel in the luminance distribution image, which corresponds to each pixel of the image, based on the portion contributing to brightness are added to the value of each pixel of the image.

A servomechanism includes a controller which dynamically estimates the resistance of the solenoid coil in an electrohydraulic valve as part of determining a level of electric voltage to apply to open the valve. The servomechanism receives a current setpoint designating a desired electric current level and senses the actual level of current flowing through the coil. A proportional term is derived from the current setpoint and the actual level of current. Creation of a derivative term is based on the difference between the current setpoint and the actual level of current. A feedforward term is produced by estimating the resistance of the electrohydraulic valve and limiting the feedforward term to a predefined range of acceptable values. The proportional term, derivative term, and the feedforward term are summed to define a desired voltage level, and a PWM signal for driving the electrohydraulic valve is generated based on the desired voltage level.

An earplug has an earplug body (12) with a front sealing portion (20) that seals to a person's ear canal, a body rear portion (22) that lies out of the ear canal, and a passage (26) that extends along the body axis and that allows environmental sound to flow into the ear canal when the passage is not blocked. The body rear portion has a lateral slot (30), and the earplug includes a blocking element (14) that is laterally (L) slidable along the slot. The blocking element can slide between a first position (14A) wherein a hole (32) in the element is not aligned with the passage to prevent sound from reaching the ear canal, and a second position (14B) wherein the hole is aligned with the passage to allow sound to reach the passage.

In one aspect, the present invention is directed to a technique of, and circuitry and system for enhancing the performance of data communication systems using receiver based decision feedback equalization circuitry. In one embodiment, the equalization circuitry and technique employs a plurality of data slicers (for example, two) to receive an analog input and output a binary value based on the reference or slicer level. The output of the data slicers is provided to logic circuitry to determine whether the analog input was a binary high or binary low. In those instances where the data slicers “agree” and both indicate either a high or a low, the logic circuitry outputs the corresponding binary value. In those instances where the data slicer do not “agree”—that is, where one data slicer indicates the input to be a binary or logic high value and the other data slicer indicates the input to be a binary or logic low value, in one embodiment, the logic circuitry outputs the complement of the previous binary value. In another embodiment, the logic circuitry selects the output from the slicer that changed its output from the previous binary value. In yet another embodiment where the slicers do not “agree”, the logic circuitry selects the decision of the data slicer with higher slicer value if the previous binary value was “high”, or selects the decision of the data slicer with the lower slicer value if the previous binary value was “low”. The data slicers employ slicer levels that may be fixed, pre-programmed, predetermined, preset, changed, modified, optimized, enhanced and/or programmed or re-programmed (for example, adaptively) before or during operation of the decision feedback equalization circuitry.
