Abstract:
The invention relates to a device for detecting of an UV radiation as well as a housing which is part of the device and which receives a light sensor. The sensor housing comprises the following features: a wall which encloses the sensor; the wall comprises a region of incidence facing one or several UV radiation sources (1) as well as a region opposite to the UV radiation sources (1); at least the region of incidence consists of a material transparent to UV rays; the whole sensor housing (4) respectively the sensor housing (4) without the region opposite to the UV radiation source (1) is made of one single piece and free of openings.
Abstract:
A portable UV detector is provided having a printed circuit board, a display module and multiple batteries housed in a cylindrical body. A display panel window is located on the external wall of the cylindrical body to mount the display module with an appropriate UV level indicator. A light detector located underneath the filtering lens is enabled at the push of a button to measure the intensity of incoming UV light and display a corresponding level on the display module.
Abstract:
The invention is a pneumatically actuated energy collection device. The device includes a support which has an energy collector thereon. A shutter is slidably attached to the support and can be moved between a first “closed” position and a second “open” position. In its first position, the shutter covers the collector and in its second position, the shutter uncovers the collector. The shutter is biased into one of the positions. A chamber is disposed adjacent to the shutter so that when the chamber is pressurized, the shutter bias is overcome and the shutter is moved between the first position and the second position.
Abstract:
A dual-channel sunload sensor capable of sensing the intensity and directionality of the solar radiative power entering the cabin of a car through the windshield, for the purpose of providing information to the data processing system of the car that enables a control of the air conditioning system that optimizes the comfort of the driver and of the front passenger. Signals from the sensor offer reliable indications of the solar load power and directionality for a wide range of angular positions of the sun. The sensor includes two convex transparent parts collecting light each toward a respective photodiode, the transparent parts being separated by an opaque portion.
Abstract:
An optical detector is formed so that gate traces formed during molding of a lens member do not allow additional stray light to enter a light detecting element. A lens member for focusing incident light is mounted forward of a cylinder used for blocking extraneous light. An IC light detecting device used for range-finding is mounted behind the cylinder. The lens member has lens portions and a peripheral portion surrounding the lens portions. The lens portions and the peripheral portion are integrally molded from a transparent plastic material. Positioning protrusions extend from an outer peripheral surface of the lens member. Recessed portions in which the positioning protrusions can be engaged are formed in a front outer peripheral portion of the cylinder. Gate traces formed during molding are located in the positioning protrusions. Consequently, additional recessed portions are not needed to accommodate the gate traces.
Abstract:
A symmetric monitor calibrator for mounting on a cathode ray tube or monitor with a surface. The calibrator has a case that holds electronic and optic components. Suction cups hold the calibrator to the surface, in which the suction cups are attached to the end of supporting elements that surround the case. At least three supporting elements with a common connecting point to form one support structure are connected to the top of the case. The supporting elements extend out creating a greater diameter than the case. The supporting elements and therefore suction cups uniformly surround the center point of the case to prevent rotation caused by the effects of gravity.
Abstract:
An optoelectronic sensor device with a housing (1) which can be adapted to a host of installation situations with the housing (1) unchanged is achieved in that there are an optics module (2) and an electronics module (3) in the housing (1).
Abstract:
An ultraviolet (UV) radiometer includes as one component a data collection unit which is sufficiently small that it can be placed in UV curing applications which have normally been inaccessible as another component a data reader into which the data collection unit is inserted for displaying and/or processing the actual data collected by the data collection unit during a process run. Because of its small size, the data collection unit makes it possible to obtain true process control in applications that could not previously be monitored. After making a dosage measurement, the data collection unit is inserted into the data reader to display the actual data collected during a UV curing run. After reading the data in the data collection unit, the data reader clears the previously stored data and resets the unit to take a new dosage reading.
Abstract:
A close contact type image sensor having an improved structure and manufacturing process utilizes a body having integral reflective surfaces to eliminate assembly steps. The body and reflective surfaces are formed using different plastic materials in a single injection molding process. A material having highly reflective characteristics is used for the reflective surfaces. A light source is aligned with the reflective surface by pins in the sensor body which are inserted into holes in the light source. Alternatively, the light source can be mounted on a printed circuit board which has holes that are aligned with the pins. A self focusing lens is mounted in the body to focus reflected light onto a light detector which is mounted on a printed circuit board. A transparent cover piece is mounted in an opening in the body. Flat spring clips secure the printed circuit board to the body of the sensor.
Abstract:
A method for measuring total column ozone in the atmosphere and an instrument for implementing this method is disclosed. The ozone meter generally includes a first photodetector sensitive to UV-B only, a second photodetector sensitive to visible light only, a position-sensitive detector for measuring solar zenith angle and a microprocessor for normalizing the UV-B response relative to the visible response and applying one or more stored algorithms to the measured and normalized UV-B value and solar zenith angle to correlate total column ozone to a set of measured or modeled surface irradiances covering a wide range of solar zenith angles and total column ozone values.
