Abstract:
Mechanisms for interferer detection can detect interferers by detecting elevated signal amplitudes in one or more of a plurality of bins (or bands) in a frequency range between a maximum frequency (fMAX) and a minimum frequency (fMIN). To perform rapid interferer detection, the mechanisms downconvert an input signal x(t) with a local oscillator (LO) to a complex baseband signal xI(t)+jxQ(t). xI(t) and xQ(t) are then multiplied by m unique pseudorandom noise (PN) sequences (e.g., Gold sequences) gm(t) to produce m branch signals for I and m branch signals for Q. The branch signals are then low pass filtered, converted from analog to digital form, and pairwise combined by a pairwise complex combiner. Finally, a support recovery function is used to identify interferers.

Abstract:
A three-sided channel coupler for connecting the upper and lower portions of a U-shaped sign post, the coupler comprising two U-shaped elements, an outer three-sided, U-shaped element and an inner, three-sided U-shaped element, the three sides of each element comprising a transverse face and two lateral legs, the inner element being smaller than the outer element, a plurality of cross-braces attached to the two lateral legs of each element to hold the two elements together and a plurality of vertical ribs on the inner surface of the outer element and on the outer surface of the inner element.
Abstract:
Representing a face by jointly quantizing features and spatial location to perform implicit elastic matching between features. A plurality of the features are extracted from a face image and expanded with a corresponding spatial location in the face image. Each of the expanded features is quantized based on one or more randomized decision trees. A histogram of the quantized features is calculated to represent the face image. The histogram is compared to histograms of other face images to identify a match, or to calculate a distance metric representative of a difference between faces.

Abstract:
A twine cutting apparatus in combination with an automated grass baler having a twine holding reel for feeding wrapping twine to the baled grass. The apparatus has a pivoted knife arm with a first end structured to cooperate with a cam surface for actuating the knife arm to a cutting position and an opposite end for mounting a twine cutting knife. The twine cutting knife is formed with an elongated, serrated cutting edge extending a distance greater than the radius of the twine holding disc presenting an elongated cutting surface to said twine.

Abstract:
An annuloplasty ring holder including a head having an upper surface and an annuloplasty ring receiving surface facing opposite the upper surface. The annuloplasty ring holder also includes means for attaching an annuloplasty ring to the annuloplasty ring receiving surface. The means for attaching an annuloplasty ring to the annuloplasty ring receiving surface may include one or more suture guides operatively associated with the head and configured to position one or more sutures to removably associate an annuloplasty ring with the annuloplasty ring receiving surface. The head may include a central hub and more than one spoke radiating out from the central hub. If the head is thus configured, each spoke will include a portion of the annuloplasty ring receiving surface.

Abstract:
AT4 receptor agonists are potent activators of angiogenesis and can be used to treat diseases that are characterized by vascular insufficiency. AT4 receptor antagonists, which are potent inhibitors of angiogenesis, and can be used as anti-angiogenic agents for the treatment of cancer, diabetic retinopathy, rheumatoid arthritis, psoriasis, atherosclerotic plaque formation, and any disease process that is characterized by excessive, undesired or inappropriate angiogenesis or proliferation of endothelial cells.
