Title: Ridge vent with powered forced air ventilation
Inventor: RAILKAR SUDHIR
IPC: F24F7/02
Filed: 2010-11-10
Abstract: A ridge vent with powered forced air ventilation includes a ridge vent that is configured to be installed along the ridge of a roof covering an elongated ridge slot on either side of a ridge beam of the roof. Hot air from the attic below escapes by convection through the ridge slot and is expelled to ambient atmosphere through the ridge vent. A blower is mounted in a blower opening formed at a predetermined location along the ridge vent on one side of the ridge beam. The blower includes a blower housing forming an inlet within the attic and an outlet oriented to force air upwardly through the vent slot to be expelled through the ridge vent. A pair of baffles are hingedly secured to the housing adjacent its outlet and can be hinged up for dropping the blower through the blower opening during installation, and then hinged down and attached to a roof deck covering the blower opening and a portion of the ridge slot on the other side of the ridge beam. The baffles secure the blower and help to isolate its outlet from the attic space below. An impeller is disposed in the housing and is driven by an electric motor, which may be driven by electricity from a solar panel, electricity from a household electrical service, or both depending upon availability of sunlight and other conditions.

Abstract: An apparatus (40) for measuring erosion of an edge (32) of an aerofoil portion (30) of a fan blade (26) comprises a laser source (42) to direct light at a position on the edge (32) of the fan blade (26). A detector (44) detects light reflected from the position on the edge (32) of the fan blade (26). A computer (480 measures the distance from the laser source (42) to points on the edge (32) of the fan blade (26) to produce a profile of the edge (32) in terms of x and z coordinates. The computer (48) calculates the radial distances of points on the edge (32) of the fan blade (26) from a centroid of the profile. The computer (48) detects local peaks (P) in the distance of points from the centroid of the profile. The computer (48) selects two local peaks (P1, P2) with the greatest distance there between. The computer (48) determines the distance (D1) between the two local peaks (P1, P2) and compares the determined distance (D1) and a predetermined distance to determine if there is unacceptable erosion.

Abstract: A system and method of estimating the body shape of an individual from input data such as images or range maps. The body may appear in one or more poses captured at different times and a consistent body shape is computed for all poses. The body may appear in minimal tight-fitting clothing or in normal clothing wherein the described method produces an estimate of the body shape under the clothing. Clothed or bare regions of the body are detected via image classification and the fitting method is adapted to treat each region differently. Body shapes are represented parametrically and are matched to other bodies based on shape similarity and other features. Standard measurements are extracted using parametric or non-parametric functions of body shape. The system components support many applications in body scanning, advertising, social networking, collaborative filtering and Internet clothing shopping.

Abstract: Systems and methods are provided for analyzing data to determine properties of a PCR process or other process exhibiting amplification or growth. Data representing an amplification can be distinguished from data representing a jump or other error. A modified sigmoid function containing a drift term may be used in determining the properties. A multi stage functional fit of the amplification data can provide increased accuracy and consistency of one or more of the properties. A baseline of the amplification data can be determined by analyzing an integrated area of a first derivative function of the data. A reference quantitation value can also be determined from locations of maxima of different derivative functions of the amplification data, e.g., a weighted average of the maxima locations for the second and third derivatives may be used.
