摘要： A system for remotely sensing light from within a monitored environment containing one or more retro-reflective optical elements. The system includes an illuminator including a light source and a reflector unit comprising a deformable mirror arranged to receive light from the light source and to reflect the received light. This outputs illumination light from the illuminator for illuminating the optical element(s) within the monitored environment. A detector is arranged to receive light returned by the one or more retro-reflective optical elements in response to the illumination light. The detector determines a wavefront of the returned light and detects a property of the monitored environment according to the returned light. The reflector unit is arranged to deform the deformable mirror according to the determined wavefront such that light from the light source is reflected by the deformable mirror so deformed to output illumination light with a modified wavefront.

摘要： In accordance with an embodiment, a device includes an interface configured for obtaining at least one measurement signal from a temperature sensor. In a first time interval the at least one measurement signal comprises information about a temperature-dependent voltage difference between a first temperature-dependent voltage at a first diode of the temperature sensor and a second temperature-dependent voltage at a second diode of the temperature sensor. In a second time interval the at least one measurement signal comprises information about a measurement value of a temperature-dependent voltage at a temperature-dependent electrical component of the temperature sensor.

摘要： A pressure sensor and its use for visually determining whether a preselected pressure threshold has been achieved, for example during high pressure processing treatment of a foodstuff The pressure sensor includes a contained color-changing system having a dye, a developer, and a solvent; upon achievement of the preselected pressure threshold, the dye and the developer interact, resulting in a visible color change. Further, the visible color change can be retained upon a decrease in pressure and upon an increase in temperature, thereby effectively recording the achievement of the preselected pressure threshold during the high pressure processing treatment.

摘要： A biometric information detecting apparatus is provided. The biometric information detecting apparatus includes a fixing unit disposed on a lower structure, and a pressure pulse wave measuring unit that is supported by the fixing unit and separate from the lower structure. An optical pulse wave measuring unit is disposed on the pressure pulse wave measuring unit. The optical pulse wave measuring unit may contact a surface of a subject's body. A pressure pulse wave of the subject's body may be measured by the pressure pulse wave measuring unit and an optical pulse wave of the subject's body may be measured by the optical pulse wave measuring unit, at the same time.

摘要： The present invention concerns a group (10) and method for measuring the pressure in closed containers (30) made from optically transparent material at least at a portion of a top space (31) thereof, and a filling and/or packaging plant (100) using the measuring group. In particular the present invention concerns a group and a method for contactlessly measuring the pressure in closed containers, able to be used directly in automatic filling and/or packaging plants operating at high speed, without the need to stop or slow down such plants or in any case to pick up the containers from the same. The measuring group for measuring the pressure in closed containers (30) made from optically transparent material at least at a portion of a top space (31) thereof, comprises at least one inspection area (20) adapted for the passage of at least one portion of a top space (31) of a closed container (30) of said closed containers; at least one laser source (11) with optical axis (A) for the emission of a laser beam at a wavelength tunable with an absorption wavelength of a gas contained in the top space (31) of the closed container (30), the at least one laser source (11) being positioned so as to direct the laser beam towards the at least one inspection area (20); at least one detector (12) positioned so as to detect at least one portion of the laser beam emitted by the laser source (11) once it has travelled through the inspection area (20) and to provide in output data representative of an absorption spectrum of said gas as a consequence of the passage of the laser beam through the inspection area (20); at least one device (14,14′) for detecting the signal acquisition time period corresponding to the passage of said at least one portion of a top space (31) of a closed container (30) through the inspection area; and is characterised in that it comprises means (41) for identifying signal contributions useful for the pressure measurement amongst the data representative of an absorption spectrum acquired during the signal acquisition time period.

摘要： The present invention provides a method of sensing pressure in a region of interest by providing a plurality of metallic particles operatively associated with one another in the region of interest (for example, wherein the metallic particles sustain a plasmon upon excitation), and with the metallic particles configured or positioned in relationship to one another so that a physical property of the particles (for example, the energy of the plasmon) varies in response to pressure; measuring the physical property of the metallic particles that varies in response to pressure; and then determining the pressure in the region of interest from the detected physical property (e.g., resistance, energy of the plasmon). Compositions, articles and formulations for carrying out the method in industrial and biomedical applications are also described.
