Abstract:
A method of inspecting a lateral pipe extending from a manhole, the method comprising: (a) extending an imaging head into the manhole using a positioning system, the imaging head comprising an imaging device and at least one lamp capable of producing a light beam, the positioning system comprising an elongated member and a targeting fixture operatively connected thereto, the imaging head being attached to one end of the elongated member, the targeting fixture having a distal end biased outwardly from the imaging head; (b) placing the distal end on a rigid surface proximate to the lateral pipe; (c) pushing down on the elongated member such that the distal end resiliently moves toward the imaging head, thereby allowing the light beam to be centered approximately in the lateral pipe; and (d) imaging a target located within the lateral pipe.
Abstract:
An apparatus for holding a generally flat color sample in a plurality of fixed and repeatable positions in proximity with the optics of a portable color instrument with a uniform and repeatable force. The apparatus has a platform upon which the portable color instrument is secured, a sample stage with multiple index planes upon which a color sample is placed, and a device which urges a pressure foot against the color sample, thereby holding the color sample in position on the stage with a uniform and repeatable force.
Abstract:
표면 검사 장치는 기판을 보유지지하는 스테이지, 광원, 광원으로부터의 광을 제1 방향을 따라 복수회에 걸쳐 주사하는 주사 광학계, 제1 방향과 교차하는 제2 방향으로 스테이지를 주사하는 스테이지 주사 기구, 및 기판으로부터의 산란광을 검출하는 검출기를 포함한다. 기판의 검사 대상 영역은 주사 광학계 및 스테이지 주사 기구의 동작에 의해 광원으로부터의 광에 의해 주사된다. 주사 광학계의 색수차가 미리결정된 파장 범위 내에 들어오도록 보정된다. 광원으로부터의 광의 파장의 변동 범위는 제1 방향을 따른 각각의 광 주사 동작의 주사 기간에서의 광원의 총 점등 시간의 변동에 기초하여 결정된다. 변동 범위는 미리결정된 파장 범위 내에 들어온다.
Abstract:
A high mast light pole inspection system includes a command center and a transport vehicle. The transport vehicle has a frame configured to be secured around a high mast light pole, and a plurality of sets of wheels. Each set of wheels has a spring mechanism that biases a respective set of wheels inward towards a center of the frame. The plurality of sets of wheels are wirelessly controlled from the command center. In addition, the transport vehicle includes a plurality of cameras mounted to the frame, a power supply coupled to each set of wheels and camera, and a RF digital video transmitter coupled to the plurality of cameras. The transmitter is configured to transmit a wireless multiplexed output of the cameras to the command center.
Abstract:
Various embodiments of a light detection device (110) and a method of using such device (110) are disclosed. In one or more embodiments, the light detection device (110) includes a housing (112) including a top surface (114) and a bottom surface (116), where the housing (112) extends along a housing axis (104) between the top surface (114) and the bottom surface (116); and a support member (160) connected to the housing (112) and adapted to be selectively moved from a closed position to an open position. The support member (160) is further adapted to maintain the light detection device (110) in an upright position when the bottom surface (116) and the support member (160) are in contact with a working surface (102) and the support member (160) is in the open position.
Abstract:
The invention relates to a unit and method for detection of presence of oil on the water surface or in the water column. Unit comprises a sensor (2), whereby the sensor is connected to electronic compartment followed by microprocessor controller (4) with embedded software for carrying out necessary analyses of reflected signals received by the sensor (2). The microprocessor controller (4) is connected to communication means (5) for transmitting an alarm signal through external communication line (6) in case of oil pollution. All elements mentioned above are supplied by external power supply (7) and are accommodated into a waterproof housing (8). The sensor comprises the probe light source formed by a pulsed UV LED (10), collimating optics (10') and narrow band optical filter (20), at least one dichroic mirror (30), a projection-receiving lens (40), at least one optical filter (50), at least one photodetector (60) and a reference photodetector (70).
