Abstract: A constant-air inflatable decoration has an inflatable body defined by walls and an inflation port formed with one of the walls. A blower is located at the inflation port and incorporates a blower fan adapted for generating continuous airflow from an outside of the inflatable body to an inside of the inflatable body. The blower operates to continuously force air into the inflatable body to maintain an inflated three-dimensional shape. A projector is mounted adjacent the blower and faces inside the inflatable body. The projector incorporates a light source and a projection lens configured for magnifying and casting an image onto an opposite display surface of the inflatable body. The projector resides within a direct path of airflow generated by the blower fan, thereby continuously cooling the light source of the projector during operation of the blower.

Abstract: A computer implemented method of decoding a signal. The method includes receiving a signal (which may be an electromagnetic signal), sampling the received signal to generate an input waveform having magnitude and phase components, applying a transform operation to the input waveform to generate a first decoded signal, and outputting the first decoded signal. The transform operation includes pre-processing the input waveform to generate a mirrored inverted waveform and applying a continuous wavelet transform to the mirrored inverted waveform to generate the first decoded signal. This allows inversion of the frequency and temporal resolution of the continuous wavelet transform, thereby enabling improved temporal and frequency decoding of a signal. The method is particularly suitable for signal filters and filtering units.

Abstract: A cam-driven valve system includes a valve housing configured to define a plurality of fluid passageways and to support an array of sliding gate fluid valves in the fluid passageways in such a way that the flow of fluid therethrough is controlled. The system includes a plurality of cams supported on a cam shaft. The cam shaft is arranged so that each cam is associated with a corresponding sliding gate valve. Rotation of the cam shaft results in actuation of the valves via the cams. The cams of the cam shaft vary in shape and size.

Abstract: A fuel system that provides fuel to an internal combustion engine includes a fuel tank and a fuel pump configured to receive fluid from the fuel tank and supply pressurized fluid to the engine via a fuel filter. The filter receives fuel from the pump and provides filtered fuel to the engine. The filter is disposed in a filter chamber of a filter housing. The filter housing includes a fuel inlet that directs fuel received from the fuel pump into the filter chamber, a fuel outlet that directs filtered fuel received from the fuel filter to the fuel supply line, and a bypass outlet that directs fuel not drawn into the fuel filter by the internal combustion engine to a fuel pressure regulator. The regulator receives the unfiltered fuel from the bypass outlet and returns the unfiltered fuel to the fuel tank.

Abstract: Disclosed are some implementations of systems, apparatus, methods and computer program products for facilitating the implementation of declarative transaction control. A database transaction control configuration associated with an element of a process flow can be obtained via a graphical user interface (GUI) and stored in association the element. The database transaction control configuration indicates whether a pending database transaction is to be committed to a database prior to executing a set of computer-readable instructions corresponding to the element. During execution of the process flow, the database transaction control configuration is accessed and it is determined whether a currently pending database transaction is to be committed to a database prior to executing a set of computer-readable instructions corresponding to the element.

The bonding step and the hot forming step are performed in the same rig, thereby optimizing process time and component quality.

Abstract: Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.
