20110271986 | LOW-PRESSURE SLUDGE REMOVAL METHOD AND APPARATUS USING COHERENT JET NOZZLES - Provided area cleaning apparatus and an associated method of using the disclosed apparatus wherein the apparatus utilizes one or more nozzles configured to provide a coherent stream of one or more cleaning fluids for removing accumulated fine particulate matter, sludge, from surfaces. The nozzles may be sized, arranged and configured to provide coherent streams that maintain the initial stream diameter for a substantial portion of the maximum dimension of the space being cleaned. The apparatus and method are expected to be particularly useful in the cleaning of heat exchangers incorporating a plurality of substantially vertical and narrowly spaced tubes by directing cleansing streams along a plurality of intertube spaces. | 11-10-2011 |

20140347443 | INDIRECT REFLECTION SUPPRESSION IN DEPTH IMAGING - A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features. | 11-27-2014 |

20120140484 | LIGHT SOURCE MODULE - An embodiment of the invention provides apparatus for providing light pulses comprising a light source electrically connected to a low inductance configuration of electrodes for electrically connecting the light source to a power supply. | 06-07-2012 |
20120229611 | ILLUMINATOR WITH REFRACTIVE OPTICAL ELEMENT - An illumination system having a refractive optical element that compensates for dependence in irradiance of images of objects captured by a photosensor is provided. The refractive optical element may structure the light such that similar objects in the same spherical surface in the field of view of the camera have the same irradiance on the camera photosensor. The illumination system may have an image sensor, a light source, and a refractive optical element. The image sensor has a photosensor that captures images of objects in a field of view. The irradiance of images of objects having a given exitance that are captured by the photosensor may depend on angular displacement from an optical axis of the image sensor. The refractive optical structures light from the light source to illuminate the field of view to compensate for the dependence of irradiance on angular displacement from the optical axis. | 09-13-2012 |
20130147353 | LIGHT SOURCE PACKAGE - A light source package for selectively interrupting power to a light source is provided. An optical element is positioned to reflect a reflected portion of the light from the light source. The reflected portion impinges upon a base that includes a roof panel with a light source side and a sensor side that is opposite to the light source side. The light source side of the roof panel receives the reflected portion of the light and transmits a transmitted portion of the light through the roof panel. The sensor side of the roof panel includes a recess in which a sensing component is located. The sensing component receives the transmitted portion of the light and is be configured to interrupt power to the light source when the transmitted portion of the light is below a threshold. | 06-13-2013 |

20130116049 | TIME-OF-FLIGHT CAMERA WITH GUIDED LIGHT - A time-of-flight 3D camera and related method for illuminating a camera field of view and capturing return image light are disclosed herein. In one example, the time-of-flight 3D camera includes a light source that emits source light along an optical axis, and a collimator that receives and collimates the source light to create collimated light. A refractive diffuser is tuned to the camera field of view and receives and diffuses the collimated light to create refracted light having a varying intensity profile. The refractive diffuser guides the refracted light to illuminate the camera field of view to reduce wasted source light. | 05-09-2013 |
20150024847 | TIME-OF-FLIGHT CAMERA WITH GUIDED LIGHT - A gaming system comprising a time-of-flight 3D camera and related method for illuminating a camera field of view and capturing return image light are disclosed herein. In one example, the time-of-flight 3D camera includes a light source configured to emit source light along an optical axis, and a collimator configured to receive and collimate the source light to create collimated light. A refractive diffuser is operable to be tuned to the camera field of view and configured to receive and diffuse the collimated light to create refracted light having a varying intensity profile. The refractive diffuser is further configured to guide the refracted light to illuminate only a portion of the camera field of view to reduce wasted source light. | 01-22-2015 |
