Abstract:
A combination valve including a valve body having an inverted bi-directional valve portion and an umbrella portion is disclosed. In accordance with one aspect of the invention, a combination valve includes a valve body with a substantially cylindrical portion defining a flow path, a resilient umbrella valve portion extending annularly from the valve body and an inverted bi-directional valve portion provided in the flow path. The inverted bi-directional valve portion includes an interior surface, an exterior surface and at least one normally closed slit extending therebetween, wherein the exterior surface of the inverted bi-directional valve portion includes a generally concave curved portion when the slit is closed.
Abstract:
Scanned image content is analyzed by identifying and quantifying each of a number of pixel categories in sub-regions of a rectangular grid defined over the scanned-in image data. The counts or other quantities are compared with predetermined pixel distributions, and the sub-regions are characterized in response to the comparison. An image processing operation that depends upon the characterization can then be performed.
Abstract:
In one embodiment, a filter with a main signal path having one or more biquadratic filter sections is tuned using a tuning circuit based on a biquadratic filter that can be configured to oscillate at the filter's cutoff frequency. In one application, a tuning circuit outside of the main signal path is used to tune each biquadratic filter section of the main signal path. In another application, each filter section along the main signal path has a biquadratic filter that can oscillate and corresponding tuning elements that enable the filter section to tune itself. According to certain embodiments of the present invention, a biquadratic filter is made to oscillate by applying a common-mode voltage signal to the inputs of the filter's third transconductor cell to make the cell's transconductance go to zero. The invention may also be implemented in the context of filters having ladder structures in their main signal path.
Abstract:
In embodiments, apparatuses, methods and storage media are described that are associated with retrieval of a file stored at multiple storage locations, such as a content file. A file retrieving device may receive an identifier of multiple storage locations from which a file may be downloaded, including content delivery networks and distinct storage servers at a particular content delivery network. The decoder may retrieve portions of the file from the different indicated storage locations. The file retrieving device may be configured to assign portion sizes to various storage locations based on a history of bandwidth experienced from the various storage locations. The file retrieving device may be configured to dynamically manage retrieval of portions of the file from the multiple storage locations, such as by re-assigning a slow or stalled portion from one storage location to a faster or underutilized storage locations. Other embodiments may be described and claimed.
Abstract:
Fiber blends useful for garments with a balance of high thermal, abrasion resistance, and moisture management properties are disclosed. The fiber blends comprise a hydrophobic fiber component, a hydrophilic fiber component, a structural fiber component, and an optional antistatic fiber. Yarns, fabrics, and garments comprising the fiber blends are also disclosed. Such garments are particularly useful for occupations requiring high thermal properties and abrasion resistance, such as fire fighters, utility workers, and military personnel, without compromising comfort of the wearers by maintaining breathability and moisture management properties of the fabric.
Abstract:
A dual compression foam pad arrangement for use with surgical postioner devices is formed from a single pair of cloverleaf-shaped foam pieces. The foam piece in contact with the patient is more porous than the foam piece in contact with the positioner support plate for greater patient comfort. A solid plastic connector clip connects the pad arrangement with the surgical postioner support in press-fit relation.
Abstract:
An integer square root calculation technique determines the precise root of an input value to determine the distance between data points such as pixels in a digital image. The technique avoids division and floating point multiplication steps. An initial root estimate may be used as a seed value beginning an iterative convergence towards the final solution. A scaled error may be determined by bit shifting an error difference between a square of the root estimate and the input value. Depending on whether the scaled error satisfies a predetermined condition, the current square root estimate may be adjusted by a bit-shifted fraction of the scaled error and the scaled error is then recalculated. In certain instances, a final adjustment to the root estimate may be implemented to yield the precise square root value. Ultimately, the final root estimate may be assigned to an output value representing the desired distance.
