摘要： A stretchable strain sensor includes a light-emitting element, an optical structure, and a photo-detective element. The stretchable strain sensor is located in a path of light emitted from the light-emitting element. The optical structure is configured to have optical properties that change in response to stretching of at least a portion of the stretchable strain sensor. The photo-detective element is configured to detect light transmitted through the optical structure or reflected through the optical structure.

摘要： A system and method of non-intrusively measuring characteristics of a fluid in a substrate are provided. The fluid is located in a fluid channel in a substrate, and an electromagnetic radiation source emits an electromagnetic beam toward the fluid and the substrate such that a first part of the beam reflects off a first surface of the substrate and a second part of the beam travels through the fluid and reflects off a second surface of the substrate. A sensor detects the resulting interference pattern produced by the two parts of the beam. Changes in fringes of the interference pattern, such as shifting positions or intensities, relates to a change in the refractive index of the fluid. Since a change in refractive index relates to the density and pressure of the fluid, the changes in interference patterns can be used to discern changes in characteristics in the fluid such as pressure.

摘要： A method and system is disclosed for determining the integrity of a closed container. The method and system includes the steps of positioning the container in a surrounding, changing a gas pressure, a gas composition, a gas concentration, or any combination of gas pressure, gas concentration and gas composition, in the surrounding. Thereafter subjecting the container to an optical sensor, non-intrusively, the sensor being sensitive to at least one gas, and the sensor is configured for detecting the at least one gas inside the container. Reading a signal from the optical sensor related to a gas pressure, a gas concentration, a gas composition, or any combination of gas pressure, gas concentration, and gas composition, inside the container. The behaviour of the signal being indicative of breach in integrity of the container.

摘要： A method for measuring, from a thermal device, temperature, molecular number density, and/or pressure of a gaseous compound as function of distance, the gaseous compound absorbing at least some light. The method comprises generating, for a first wavelength band and a second wavelength band, a pulse sequence comprising a light pulse or light pulses, guiding the pulse sequence into the thermal device, and measuring, as function of time, the intensity of the scattered light at the first wavelength band and at the second wavelength band. The method further comprises determining information indicative of the differential absorption between the two wavelengths bands using measured intensities and determining the temperature, the molecular number density, and/or the pressure of the gaseous compound using the information indicative of the differential absorption between the two wavelengths bands. A thermal system arranged to carry out the method.

摘要： An adapter for connection between a luminaire and a power input for powering the luminaire comprises circuitry for modulating light output of the luminaire to contain information, or circuitry for connection to a network so that signals associated with the luminaire are communicated on the network. The adapter is placed between the luminaire and a power input for the luminaire. Methods are provided for registering and establishing communication between a gateway device and a management platform, and for registering a luminaire device with the gateway so that it can be managed by the management platform. Portions of the larger system that constitutes the remote controlled lighting system are also described, including connected wall switches, sensors, and the gateways themselves.
