Abstract: The present invention primarily relates to certain herbicidal compositions based on the herbicidal active ingredients (A) fluazifop or an ester thereof, (B) triclopyr or an ester or salt thereof and (C) a diquat dihalide salt, optionally additionally comprising (D) imazapic or a salt thereof. The invention also relates to the field of plant protection and environmental health, and to methods and uses of the herbicidal compositions of the present invention for controlling unwanted plant growth.

Abstract: An object ranging system operates by transmitting pulses derived from a frequency-swept signal and determining the beat frequency of a combination of the frequency-swept signal and its reflection from an object. A second (or higher) order harmonic is derived from the combination signal. Accordingly, determination of the beat frequency, and hence object range, is significantly enhanced. The frequency sweep is such that frequency changes occur at a substantially higher rate at the beginning of each the pulse repetition interval than at the end. Accordingly, because the frequency changes are concentrated in the period of pulse transmission, even reflections 'from a close object, where the time delay between the source signal and the reflection is very short, will cause a high beat frequency.

Abstract: A pulse sequence is produced by repeatedly selecting individual pulse trains at random from a set thereof, each pulse train meeting predetermined autocorrelation constraints and the pulse trains collectively meeting predetermined cross-correlation constraints. The pulse trains are preferably separated by gaps of random length. At least some pulse trains may be time-reverse replicas of others. The resulting sequences are particularly suitable for obstacle detection in multiuser environments.

Abstract: Aqueous herbicidal glyphosate compositions are provided, particularly sprayable, ready-to-use (RTU) formulations that are capable of inducing early visually apparent phytotoxic effects while minimizing antagonism to the glyphosate component of the composition and preserving the equally desirable attribute of prolonged control of the treated plants. The compositions combine a glyphosate component and a fatty acid component as a fast symptomology active ingredient and, in one embodiment, are enhanced by the concentration of the fatty acid component utilized and the inclusion of an agronomically acceptable inorganic ammonium salt, preferably ammonium sulfate. In another embodiment, the compositions of the present invention include a nonionic surfactant component comprising certain water-soluble, alkoxylated alcohols.

Abstract: The present invention is directed to herbicidal compositions or formulations, and to methods of using such compositions or formulations to kill, or control the growth and proliferation of, unwanted plants. In particular, the present invention is directed to herbicidal compositions or formulations, as well as their methods of use, which comprise N-phosphonomethylglycine or a herbicidal derivative thereof, a pyridine analog or a herbicidal derivative thereof, and optionally one or more suitable surfactants, with N-phosphonomethylglycine being in excess relative to the pyridine analog. Such compositions cause early visual symptoms of treatment and/or enhanced effectiveness or control when applied to the foliage of plants.

Abstract: A method of transmitting a video image including an object of interest comprises capturing a sequence of images in which the object of interest occupies a fraction of each image, tracking the object of interest by selecting and extracting a region of each image including the object of interest, and coding only the selected region of each captured image.

Abstract: The delay between a first signal and a second signal is evaluated by deriving from the first signal substantially aperiodic events, possibly by using a zero-crossing detector on a random signal, and using these events to define respective segments of the second signal. The segments are combined, e.g., by averaging, to derive a waveform which includes a feature representing coincidences of parts of the second signal associated with the derived events. The delay is determined from the position within the waveform of this feature.

Abstract: An electric lamp is provided including a sealed outer glass envelope having an arc tube therein supported from the stem of the outer glass envelope by a support frame. The support frame is attached to the stem by a stem clip to which the support frame is welded. An inert refractory fibrous material is disposed between the stem and the stem clip to provide resiliency and a friction fit therebetween.
