Abstract:
The invention relates to a radiation measuring device, especially for measuring high power radiation (10), comprising a measuring window (12) and a deflecting unit which can guide at least one part of the radiation which is to be measured (10) from the measuring window (12) to a sensor unit (14). According to the invention, the deflecting unit comprises at least one bar (16) into which the radiation (10) is injected via the measuring window (12), parallel to the longitudinal extension (18) thereof, via a side (70). The radiation is retransmitted along the longitudinal extension of the surface (18) bar to the sensor unit (14).
Abstract:
A light sensor is provided including a light transducer for accumulating charge in proportion to light incident thereon over an integration period; and a light-to-pulse circuit in communication with the light transducer, the light-to-pulse circuit operative to output a pulse having a pulse width based on the charge accumulated by the light transducer. The light-to-pulse circuit may include a one shot logic circuit that contributes to generation of the pulse. The light sensor may include an input/output pad, a capacitor provided at the input/output pad for blocking static electricity, an input low pass filter provided at the input/output pad for blocking electromagnetic interference, and/or a bandgap voltage reference circuit connected to a power source having a supply voltage level in a range of about 3.3V to about 5.0V, and for generating stable reference voltages throughout the supply voltage level range.
Abstract:
A computer may include a database and a power reducing routine. The database may be configured to store an input power level of an input laser beam transmitted onto and storing power within a gain module. The database may be further configured to store a discharge power level of at least partially discharged stored power discharged from the gain module through an output laser beam. The database may also be configured to store a power safety differential limit. The power reducing routine may include an algorithm. The algorithm may be configured to calculate a power differential by subtracting the discharge power level from the input power level, and to at least one of reduce power to and shut down the input laser beam if the calculated power differential exceeds the power safety differential limit.
Abstract:
Elemento de prevención sobre superficies transparentes de edificios para la protección y terapia de ojos. Resulta de la aplicación de un filtro con pigmentación amarilla sobre las superficies transparentes o traslúcidas para el uso en edificaciones donde pudiera encontrarse la persona, con el fin de protegerlos de las longitudes de onda corta del espectro visible desde 500 a 380 nm. Esta invención elude las dificultades y riesgos de las técnicas existentes para dotar de esta protección a los ojos sanos y operados de cataratas y mejorar la de aquellos en procesos neurodegenerativos, lográndolo con la simple aplicación de un filtro a las superficies transparentes o traslúcidas de cualquier edificación donde pudiera encontrarse la persona adicionando una protección frente a agentes neurodegenerativos incluidos en la luz (longitudes de onda corta).
Abstract:
An infrared detector includes a circuit block carrying an infrared sensor element and electronic components. The circuit block is composed of a dielectric resin layer and a first substrate formed with a circuit pattern and mounting the electronic components. The dielectric resin layer is formed in its top with a recess which defines around its periphery with a shoulder for supporting opposite ends of the infrared sensor. The first substrate is integrated to the lower end of the dielectric resin layer with at least one of the electronic components being molded into the dielectric resin layer to make the circuit block of a unified mold structure. Thus, a part or all of the electronic components are molded into the dielectric layer to realize the circuit block of a simple and low profile structure, while retaining an advantage of keeping the infrared sensor element sufficiently away from the electronic components and an associated electronic circuit, thereby assuring to give the infrared detector which is simple in construction, economical in cost, and reliable in the infrared detection.
