Abstract:
A method for generating a set of one or more elements of a fingerprint for a document, the document comprising a semantic construct having one or more ordered words, the method comprising the steps of: defining a range of sizes for a fingerprint element; dividing the ordered words of the semantic construct into a set of one or more mutually exclusive fingerprint elements, wherein each of the one or more mutually exclusive fingerprint elements includes a number of adjacent words, the number being within the range of sizes for a fingerprint element; and responsive to a determination that the set of mutually exclusive fingerprint elements excludes a word from the semantic construct, discarding the excluded word.

Abstract:
A door jammer device for preventing opening from the outside of a inward-opening door is disclosed, comprising a substantially U-shaped member having a shorter arm, a longer arm, and a base. Screw means are installed though a threaded hole through the longer arm towards the shorter arm, for attaching the member to the door by clamping the door between the screw means and the shorter arm. A jamming member is pivotally attached to the longer arm and angles downwardly away from the U-shaped member to engage the floor. Thus, a door may be locked by tightening the screw means to clamp the device to the outside edge of the door near the floor, such that the jamming member engages the floor. The jamming member has downwardly protruding teeth at its floor-engaging end, and angles downwardly at an angle of approximately 15 to 20 degrees from the horizontal.
Abstract:
A roll-on liquid applicator having an applicator ball disposed within a dispensing chamber and a spring element with a valve head portion. The spring element effects a distally-directed force to press the valve head against the valve opening to maintain a sealing closure of the valve opening against flow of the liquid from the feed chamber into the dispensing chamber. The valve head has a ball support structure which extends distally through the valve opening to contact with the applicator ball so that when the ball is inwardly displaced by force applied thereto, the valve head moves axially inward from the closed-valve position to the open-valve position, thereby moving the valve head from the closed-valve position in contact with the valve opening toward the open-valve position which allows liquid from the feed chamber to enter the dispensing chamber.
Abstract:
A method of manufacturing a porous cementitious product, which method comprises: forming a cementitious premix; casting the premix in a desired configuration; generating gas bubbles within the premix; and curing the premix, wherein gas bubbles are generated and/or collapsed at specific locations within the premix in order to produce a porosity profile along a cross-section of the product such that the product comprises a relatively low density core region and higher density outer regions.
Abstract:
Meter electronics (20) for processing sensor signals for a multi-phase flow material in a flowmeter (5) is provided according to an embodiment of the invention. The meter electronics (20) includes an interface (201) for receiving first and second sensor signals (210 and 211) for the multi-phase flow material and a processing system (203). The processing system (203) is configured to receive the first sensor signal (210) and the second sensor signal (211), generate a first ninety degree phase shift (213) from the first sensor signal (210) and generate a second ninety degree phase shift (214) from the second sensor signal (211), compute a frequency (221) using one of the first ninety degree phase shift (213) or the second ninety degree phase shift (214), compute a phase difference (220) using one or more of the first ninety degree phase shift (213) and the second ninety degree phase shift (214), and compute one or more of a mass flow rate (223), a density (224), or a volume flow rate (225) for the multi-phase flow material.
Abstract:
An aquatic training device (150) including: a drag member (160) including an inlet (161), an outlet (162) and at least one side wall (163) extending between the inlet (161) and the outlet (162); and a link (170), for towing the drag member (160), coupled to the at least one side wall (163) adjacent the inlet (161); wherein the drag member (160) includes at least one drag inducer (164) formed in or attached to the at least one side wall (163).
Abstract:
An apparatus for coating or breading food products, such as chicken parts, includes a rotating drum with end caps closing the loading and discharge ends of the drum. Apertures are defined in the end caps for the passage of the food product, in which the apertures are situated along the central axis of the drum. A spiral grate inside the drum receives the food product and conveys it toward the discharge end. The spiral grate supports the food product proximate the central axis so that the product is more fully and uniformly coated with the particulate material. The spiral grate is configured with a gap at the discharge end so that a portion of a discharge ramp may be disposed within the gap to receive the prepared food product for discharge.
Abstract:
Meter electronics (20) for determining a mass fraction of flow components in a flow material flowing is provided according to an embodiment of the invention. The meter electronics (20) include an interface (201) for receiving a frequency response of the flow material and a processing system (203). The processing system (203) receives the frequency response from the interface (201) and breaks out the frequency response into at least a gas frequency component and a fluid frequency component. The processing system (203) determines an overall density from the frequency response and determines a gas density from the gas frequency component. The processing system (203) determines the void fraction of gas from the frequency response and one or more of the gas frequency component and the fluid frequency component. The processing system (203) determines the mass fraction from the void fraction of gas multiplied by a ratio of the gas density divided by the overall density.
