Abstract: A push-to-press inflation adaptor is provided for use with an English valve and includes a valve connector, a connection barrel, a coupler, an air tube, and a spring. The valve connector includes a first movement hole, a positioning cavity, a communication compartment, a valve opening and a constraint opening. The connection barrel is coupled to the valve connector. The connection barrel includes a second movement hole and an air tube opening. The coupler is received in the first movement hole and the second movement hole of the valve connector and the connection barrel and is reciprocally movable through application of a force thereto. The air tube is received through the air tube opening into the connection barrel to be jointed to the coupler. The spring is supported between the coupler and the connection barrel to provide a preloading force to bias the coupler in a direction toward the constraint opening.

Abstract: An underground steel-concrete structure pipeline with a spiral composite reinforcement ring on an inner wall and a manufacturing method thereof. The pipeline includes a pipe body, multiple rows of concrete overflow holes spirally arranged on a pipe wall of the pipe body, a reinforcement ring capable of wrapping the concrete overflow holes, and concrete is filled in a hollow cavity between the reinforcement ring and the pipe wall to form a spiral concrete flow passage. The advantages are that the overall annular strength of the pipeline is reinforced by the reinforcement ring; the concrete filled between the reinforcement ring and the inner wall of the pipe body improves the compressive strength of the pipe body; the concrete overflowing from the overflow holes on the pipe wall combines the pipe body with a pit; and the pipeline solves the difficulty of using large-size steel structure products in underground common pipeline projects.

Abstract: A method and apparatus for analyzing a sequence of images. Signal-to-noise ratios are identified for potential tracks using a tree having hierarchies of nodes identifying potential positions for an object over a period of time and using the sequence of images. Each hierarchy in the hierarchies of nodes represents a time and the potential positions in the tree form the potential tracks for the object. A potential track is selected from the potential tracks as an established track for the object using the signal-to-noise ratios, and a detection of the object is reported.

Abstract: An ultraviolet curing ink can be sufficiently leveled, and attachment of, for example, dust can be prevented. In an ink-jet printer, a carriage capable of reciprocating in a scanning direction is mounted with an ink-jet head for ejecting a color ink and a clear ink and ultraviolet irradiation devices for emitting ultraviolet rays. A control unit performs control so that in the forward movement of the carriage, a color ink is ejected and applied to a medium, and in the backward movement of the carriage, ultraviolet rays are irradiated to the color ink deposited on the medium and the color ink is cured. Subsequently, the medium is fed in a feed direction, and the clear ink is ejected and applied to the surface of the cured color ink in the forward movement of the carriage. In the backward movement of the carriage, the clear ink applied to the medium is irradiated by ultraviolet rays and is cured.

Abstract: Disclosed are systems and methods for identifying and reporting failures of an analog-to-digital converter (ADC). Specifically, the systems and methods described herein evaluate quantization noise properties of ADCs, including delta-sigma ADCs and successive approximation register (SAR) ADCs, to verify functionality and/or identify failures. Quantization noise properties can be evaluated in the frequency domain by, for example, comparing RMS values, magnitudes, frequency spectrums, and the like, in various frequency bands to threshold values and/or to verify an expected noise shape. Quantization noise properties can additionally or alternatively be evaluated in the time domain by, for example, comparing counts of pulse widths, average pulse widths, and/or number of transitions within a sequence of pulses to threshold values and/or to similar identifiable characteristics in other pulse width bands.

Abstract: A mechanical broadhead, which has blades movable from a retracted mode to a deployed mode, is provided with ball and socket members that hold the blades in the retracted mode, and selectively release the blades to the deployed mode. The ball and socket members, which can be on the blades and/or on a retainer element, can be snapped together to provide an audible snap confirming locking of the blades in the retracted mode. The mechanical broadhead can include first and second ferrule portions removably joined with one another. The second ferrule portion can acquire a blocking mode to block a removal opening of a ferrule slot defined in the first ferrule portion so that blade cannot be removed from respective ferrule slots. The second ferrule portion can achieve a removal mode so that the blades can be removed from the slots.

Abstract: The objective of the present invention is providing a method for fabricating high quality diffractive waveplates and their arrays that exhibit high diffraction efficiency over large area, the method being capable of inexpensive large volume production. The method uses a polarization converter for converting the polarization of generally non-monochromatic and partially coherent input light beam into a pattern of periodic spatial modulation at the output of said polarization converter. A substrate carrying a photoalignment layer is exposed to said polarization modulation pattern and is coated subsequently with a liquid crystalline material. The high quality diffractive waveplates of the present invention are obtained when the exposure time of said photoalignment layer exceeds by generally an order of magnitude the time period that would be sufficient for producing homogeneous orientation of liquid crystalline materials brought in contact with said photoalignment layer.
