Title: Led-based inspection lamp with improved collimation optics
Inventor: KLIPSTEIN DONALD L
IPC: H05B37/00
Filed: 2004-07-06
Granted: 2014-05-20
Abstract: LED lamp has LEDs aimed rearwards with either a concave mirror to the rear of each LED, or one concave mirror to the rear of two or more LEDs, collecting the light from the LEDs to form a forward projecting beam. LEDs may be high power types that require heatsinking. LED lamp may have a lens forward of each LED to collimate the radiation produced by the LEDs into a beam, where at least one lens has at least one aspheric curved surface. LED lamp may have a transparent reflective optic to collimate the radiation produced by each LED into a beam. For an inspection lamp, the LEDs typically have a peak wavelength of 395 to 415 naometers for seeing the area being irradiated but not so visible as to overwhelm fluorescence of fluorescent materials to be detected. Other wavelengths may be used. LED inspection lamp has a combination of LEDs of different wavelengths or a combination of at least one LED and at least one other light source such that the lamp produces radiation suitable for detection of materials to be detected and adequately illuminates the area being irradiated. LED lamp has LEDs that produce a beam of suitable radiation with a width of 10 degrees or less without additional optics. LED inspection lamp has head attached to a flexible member, with head serving as heatsink for one or more high power LEDs. Current regulator circuits are also disclosed.

Granted: 2015-11-24
Abstract: A video signal is coded using predictive coding. The degree of quantisation that is applied is varied as a function of measures of predictive power, the idea being that a picture that is useful as a predictor for other pictures is worth coding well. These measures are formed in a pre-analysis of the pictures to obtain, for each macroblock analysed, a measure that depends on its similarity to a region for which it is a potential predictor. Preferably these measures are cumulative.

Abstract: A quantization control method used in a video encoding which encodes a video image and performs control for making an encoding bit rate approach a predetermined target bit rate. The quantization control method includes measuring a differential amount of code between a target amount of code and an amount of generated code; determining whether or not a predetermined condition has occurred; determining, when it is determined that the condition has occurred, a variation for an amount of feedback which increases or decreases a quantization step size, and changing the amount of feedback based on the determined variation; and increasing or decreasing the quantization step size based on the measured differential amount of code and the changed amount of feedback. If there are a plurality of the predetermined conditions, a final variation for the amount of feedback may be determined by applying a specific operation to variations for the amount of feedback, which are determined for the individual conditions.

Abstract: Aspects of the present invention are directed at estimating the value of an attribute at a specified geographic location. In one embodiment, a method is provided that estimates the elevation at a principal point using LiDAR data that was collected from spatially related secondary points. More specifically, the method includes identifying secondary points where sample attribute data was obtained that are within a predetermined distance to the principal point where the attribute is being estimated. A secondary point may be selected and allocated a masking zone and a determination made regarding whether one or more distant secondary points are within the area of the masking zone. In this regard, more distant secondary points that are inside a masking zone may be assigned less relevance when estimating the value of the attribute.

Abstract: L'invention concerne un procédé et un appareil permettant de combiner des messages de demande de répétition automatique hybride (HARQ) retransmis à différents niveaux dans un récepteur à multiplexage par répartition orthogonale de la fréquence (MROF) / à accès multiple par répartition orthogonale de la fréquence (AMROF). Le type de multiplexeur HARQ utilisé pour un canal particulier peut dépendre d'un nombre de critères de sélection comprenant l'ordre de modulation de la transmission, le nombre de bits nécessaires aux signaux combinés et la marge de sécurité dans la mémoire tampon HARQ. Dans certains modes de réalisation, une combinaison de différents types de multiplexeurs HARQ peut être mise en oeuvre dans un récepteur et sélectionnée sur une base canal par canal. Une sélection appropriée d'un mécanisme de combinaison HARQ peut réduire la taille de la mémoire tampon HARQ et peut permettre d'obtenir un gain de combinaison plus important par rapport aux techniques de combinaison HARQ classiques.
