Abstract: A sterilization system consisting of a mobile emitter, a sensing subsystem and a data logging subsystem is described. The emitter has one or more UV emitting lamps or devices. The sensing system comprises at least one remote UV sensor and at least one door sensor. The door sensor comprises a safety shut off door detector and may contain an emergency stop detector and arming detector to protect people from being exposed to UV energy. The system has a remote control for starting, stopping and setting system parameters which include but are not limited to: treatment time, dosage, room size, room number, unit number, floor, facility name, operator name, operator identification number, password, default dosage values, dosage, and patient identification number. The number of treatments per unit of time can be maximized because of the use of incident light measurement.

Abstract: Optical apparatus includes a primary radiation source, which emits first optical radiation along a first optical axis. A DOE includes at least an entrance surface, upon which the first optical radiation from the primary radiation source is incident, and an exit surface, through which one or more primary diffraction orders of the first optical radiation are emitted from the DOE. At least one secondary radiation source is configured to direct second optical radiation to impinge on the DOE along a second optical axis, which is non-parallel to the first optical axis, causing at least a part of the second optical radiation to be diffracted by the DOE such that one or more secondary diffraction orders of the second optical radiation are emitted through the entrance face of the DOE. At least one detector is configured to sense at least one of the secondary diffraction orders of the second optical radiation.

Abstract: In an embodiment, an arc light sensor includes: a first polarizer, a second polarizer, a magneto-optical material, a first light filter and a processing unit. The first polarizer is used for polarizing incident first target light, to form first polarized light in a first polarization direction. The second polarizer is used for polarizing incident second target light, to form second polarized light in the first polarization direction. The magneto-optical material, in a current magnetic field, uses the current magnetic field to rotate a polarization direction of the first polarized light, to form third polarized light. The first light filter is used for filtering the third polarized light, to form fourth polarized light capable of passing in a second polarization direction. The processing unit is used for determining whether the second target light is arc light according to intensity of the second polarized light and intensity of the fourth polarized light.

Abstract: The invention relates to a light module including a laser source capable of emitting a coherent light beam of given wavelength, a first sensor capable of picking up a first light signal of a wavelength lying in a first band of wavelengths centered around the given wavelength and a second sensor capable of picking up a second light signal of a wavelength lying in a second band of wavelengths centered around a wavelength distinct from the given wavelength. In particular, the light module includes a detection module capable of comparing at least one value that is a function of the signals to a threshold value and of commanding the stopping of the laser source as a function of the comparison.

Abstract: Techniques for shielding an optical sensor are described. An example of an electronic device includes an optical sensor and a combined light-focusing and electrical-shielding unit disposed over the optical sensor. The light-focusing and electrical-shielding unit has two portions. The first portion gathers light and focuses the light on the electrical sensor. The second portion encloses sides of the first portion and is coated with an electrically conductive material to shield the optical sensor from electromagnetic interference.

Abstract: The invention discloses a safety inspection detector and a goods safety inspection system. The safety inspection detector at least comprises a circuit board, a first housing, a second housing, a detection module and a connecting interface. The detection module and the connecting interface are mounted on the circuit board. The first housing is pressed and connected to a first surface of the circuit board, and the second housing is pressed and connected to a second surface of the circuit board. The first housing and the second housing can hermetically wrap the detection module and electronic devices on the circuit board, but bypass the connecting interface to realize leading-out and connection with related interconnected cables by utilizing the connecting interface. The housings can be used for sealing and protecting sensitive electronic devices in the detector, thus being moisture proof and preventing interference.
