Abstract: A safety system for residential and commercial use includes a plurality of sensor modules that may be distributed about the environment, and that are in communication with a remote server environment and with other devices over a wireless communication network (e.g., cellular, Wi-Fi). Each sensor module includes a plurality of sensors that are capable of measuring or detecting characteristics of the environment such as smoke, small particulate, large particulate, chemicals, gasses, temperature, humidity, pressure, geolocation, and other characteristics. Analysis of sensor data is performed locally on the sensor module, as well as remotely on a server, in order to fuse and consider multiple sensor data points to identify emergency and non-emergency scenarios. By fusing and analyzing sensor data emergencies can be detected more quickly, and false alarms can be filtered out and avoided.

Abstract: Aspects relate to a compact and low-cost gas analyzer that can be used for different types of gas analysis, such as air quality analysis. The gas analyzer can include a light source, a gas cell configured to receive a sample (e.g., a gas under test), a spectral sensor including a spectrometer and a detector, and an artificial intelligence (AI) engine. Light can enter the gas cell and interact with the sample to produce output light that may be measured by the spectral sensor. The resulting spectrum produced by the spectral sensor may be analyzed by the AI engine to produce a result. The gas analyzer further includes a self-calibration component configured to enable calibration of the sample spectrum to compensate for spectral drift of the spectral sensor.

In addition, the spectroscopic analyzer device includes a light source and a disposable optical component configured to receive a sample and to facilitate light interaction with the sample.

Abstract: Aspects relate to mechanisms for mass screening of samples. A portable laboratory device based on spectroscopic analysis of samples containing analytes under test can facilitate the mass screening. The portable laboratory device can include a sample head including a structure configured to facilitate application of the sample to the sample head and an optical measurement device including one or more light sources and a spectrometer. Light from the light source(s) incident on the sample may be directed to the spectrometer to obtain a spectrum of the sample. The optical measurement device can further include a data transfer device configured to provide the spectrum obtained by the spectrometer to a spectrum analyzer to produce a result from the spectrum.

Abstract: Optical processing apparatus for processing a stream of light. The apparatus includes a light input emitted, for example, by fiber optic cable. Multiple wavelength bands of light are, typically, emitted and transmitted in a direction parallel to an axis. The apparatus also includes a plurality of receptors which are positioned at defined locations spaced from one another. A diffracting member is employed to diffract the wavelength bands of light transmitted parallel to the axis. In one embodiment of the invention, the diffracting member is a controllable diffraction grating. The wavelength bands are selectively diffracted to various of the receptors. The apparatus further includes a controller for selectively adjusting the diffracting member to independently vary a particular receptor to which any one wavelength band is diffracted.

Abstract: There is provided an electrostatically-controllable actuator having a stationary electrode, with an actuating element separated from the stationary electrode by an actuation gap. The actuating element includes a mechanically constrained support region, a deflection region free to be deflected through the actuation gap, and a conducting actuation region extending from about the support region to the deflection region. A commonality in area between the actuation region and the stationary electrode is selected to produce controlled and stable displacement of the deflection region over a displacement range, e.g., extending to a specified point in the actuation gap, when an actuation voltage is applied between the actuation region and the stationary electrode. This range of stable displacement, which can be stable bending, can extend to a point greater than about ⅓ of the actuation gap, or even through the full actuation gap.
