摘要:
Systems and methods for describing video content establish video description records which include an object set (24), an object hierarchy (26) and entity relation graphs (28). Video objects can include global objects, segment objects and local objects. The video objects are further defined by a number of features organized in classes, which in turn are further defined by a number of feature descriptors (36, 38, and 40). The relationships (44) between and among the objects in the object set (24) are defined by the object hierarchy (26) and entity relation graphs (28). The video description records provide a standard vehicle for describing the content and context of video information for subsequent access and processing by computer applications such as search engines, filters and archive systems.

Provided is use of a peptide, or a derivative of a peptide, in the manufacture of a medicament effective in stimulating fibroblasts to produce fibrillin,wherein the peptide comprises an amino acid sequence present in an α-S2 casein precursor, said sequence comprising 3 or more amino acids, and not comprising at its N-terminal amino acid of the full α-S2 casein precursor. Further provided is use of a peptide, or a derivative of a peptide, in the manufacture of a medicament effective in stimulating fibroblasts to produce fibrillin, wherein the peptide has an α-S2 casein fragment activity.

An electronic measuring device is disclosed which includes a pair of wheels connected to an axle that passes through a drive gear. The drive gear is enmeshed to a second gear which, in turn, is coaxially connected to an encoder disk. The encoder disk has spaced-apart fins around its outer periphery. As the wheels turn and the encoder disk rotates, the fins and openings between the fins pass between an emitter and a receiver. The emitter and receiver are linked to a controller which calculates the distance traversed by the wheels based upon the number of fins that pass between the emitter and receiver, or with an active counting system (ACS). The controller also includes functions to establish start and stop points for a measurement and an easy means for dividing a measured distance into equal parts or segments and a means for marking the boundary points that define the segments when the measuring device is rolled back across the measured distance. The device can be used on both planar and non-planar surfaces.

An endoluminal device for deployment in a body lumen includes a radially expandable stent, a graft attached to the stent, and a plurality of indicator members affixed to the graft and adapted to form a normal pattern in response to a normal pressure differential and an abnormal pattern in response to an abnormal pressure differential across the graft. By forming different patterns at different pressure differentials, the indicator members enable the detection of a change in pressure which could be evidence of a leak. A system for detecting a change in pressure differential includes the endoluminal device and an imaging system for displaying the indicator members. A method for detecting a change in pressure includes the steps of identifying the normal pattern, implanting the device, imaging the indicator members, and comparing the imaged pattern with the normal pattern to determine whether the normal pressure or an abnormal pressure differential exists.

A combined writing instrument holder and hand support assists those who have difficulties gripping and controlling a writing instrument. The device releasably receives a writing instrument in a position where it may be brought into contact with paper. The device provides a comfortable hand support that prevents the user's hand from engaging the paper while the device is being used.

A valve arrangement for use in the cistern (8) of a toilet is described having an inlet valve (20) operated by a float (46) such that when the level of water in the cistern reaches a threshold amount, the float operates the inlet valve to substantially instantaneously close the supply of incoming water. The inlet valve of the valve arrangement is provided with an air gap or clearance (51) to eliminate, prevent or reduce siphoning of water from the cistern into the water supply when the valve is in the fully closed position. The air gap allows water within the inlet valve to drain into the cistern so as to form the air gap.

Methods of and apparatus for Nuclear Quadrupole Resonance (NQR) testing a sample containing quadrupolar nuclei exhibiting a given value of spin-lattice relaxation time, T1, are disclosed. The method comprises applying two excitation blocks to excite nuclear quadrupole resonance, there being a given delay time between the two blocks, detecting resonance response signals, and comparing the response signals from respective blocks. The delay time is less than the T1 value of the nuclei.

A disposable weight loss garment is disclosed. The garment is made from a low cost, relatively thin plastic, in lieu of vinyl or other synthetic fabrics. The garment is designed to be worn under or over traditional exercise garments, or may alternatively be designed for stand alone use. The garment may be made of clear plastic to indicate its use as an under or over garment, or may be made of an opaque material. Opening in the top and trousers are elasticated to trap body heat under the garment thereby promoting a user to sweat. Multiple garments may be contained within a single package, the package being designed to dispense one garment at a time.

An in-line profile sander is disclosed. The in-line profile sander includes a sander housing configured to be grasped by a user. A plurality of interchangeable profile sanding pads can be mounted at a head of the housing. The sander includes an in-line oscillating mechanism for moving the profile sanding pads in a linear oscillating motion.
