A shunt pulsation trap for a screw compressor reduces gas pulsation, NVH and improves off-design efficiency without using a traditional serial pulsation dampener and a sliding valve. Generally, a screw compressor with the shunt pulsation trap has a pair of multi-helical-lobe rotors housed in a compressor chamber for propelling gas flow from a suction port to a discharge port of the compressor chamber with internal compression. The shunt pulsation trap comprises an inner casing as an integral part of the compressor chamber, and an outer casing oversized surrounding the inner casing, therein housed various gas pulsation dampening means or gas pulsation energy recovery means or gas pulsation containment means, at least one injection port (trap inlet) branching off from the compressor chamber into the pulsation trap chamber and a feedback region (trap outlet) communicating with the compressor outlet.

An active antenna array is arranged to activate subsets of switchable elements causing the antenna to form a first beam having a first beam pattern, and later to form a second beam having a second beam pattern of substantially identical far field radiation pattern to the first beam pattern but with different origins. A receiver receives radiation reflected from a target back to the antenna when the antenna is configured with the first beam pattern and then when configured with the second beam pattern, and compares the phase of the radiation received at the receiver when the antenna is configured with the first beam pattern with the phase of the radiation received at the receiver when the antenna is configured with the second beam pattern to provide a phase difference signal. A target locating means determines the angular location of the target from the phase difference signal.

The method to reduce image sticking in a plasma display panel (PDP) includes four steps. There is converting a relationship between gray level and brightness of an input signal into a linear relation by a converter. Next, there is recording an image with a static image detector at time t using a frame buffer, and after a period of time Δt, comparing the image at time t with the image at time t+Δt, thereby identifying static or dynamic images in the pixel. Then, there is recording a gain of every pixel by a brightness regulator using an image gains memory buffer zone, the gain being regulated according to detection results of the static image detector. Finally, there is improving gray level performance of output images by a gray level promoter and brightness converter. Thus, method actively detects static pixels and reduces brightness in the static region for minimized image sticking.

A low frequency exponential/hyperbolic hybrid folded horn enclosure intended for use in proximity with at least one planar surface, such as a floor, ceiling, or wall, with access to the horn throat from the top of the enclosure. The horn is bifurcated at the throat and folds horizontally around a central trapezoid-shaped vertical back chamber which is reflex ported for enhanced low frequency response below the frequency cutoff of the horn. The back chamber outer sides define part of the horn channel, resulting in a relatively simple structure with a small footprint and no void internal space. The throat exponential expansion cross-sectional area is consistently maintained while the proportions of the throat channels are elongated to the height of the enclosure,

Within an intermediate vacuum chamber next to an ionization chamber maintained at atmospheric pressure, an electrode group of a radio-frequency carpet composed of a plurality of concentrically arranged ring electrodes is placed before a skimmer, with its central axis coinciding with that of an ion-passing hole. Each ring electrode has a circular radial sectional shape. Radio-frequency voltages with mutually inverted phases are applied to the ring electrodes neighboring each other in the radial direction. Additionally, a different level of direct-current voltage is applied to each ring electrode to create a potential which is sloped downward from the outer ring electrode to the inner ring electrode. The circular cross section of the electrode produces a steep pseudo-potential near the electrode and thereby increases the repulsive force which acts on the ions to repel them from the electrode.
