Abstract:
The present invention relates an optical sensor. In particular, the present invention relates to an optical sensor for detecting chemical components in a fluid.The present invention comprises two or more sensors, each being configured to detect one or more chemicals in a fluid, or one or more properties of the fluid, and two or more light sources. Each sensor is associated with one light source, and each sensor is configured to emit or reflect light in response to light from the light source incident on the sensor. The emitted or reflected light is dependent upon the presence of a chemical or a property of the fluid. The two or more light sources and two or more sensors are arranged around a single light detector, which detects the colour and/or intensity of the light being emitted or reflected by the sensor. Data from the light detector is passed to a remote processor for processing.

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.
