Abstract: A method includes receiving, from a subscriber device, a request including virtual region characteristics and an occupancy threshold, and determining, using image data captured by a camera and the virtual region characteristics, a virtual region corresponding to a portion of a physical region within a field of view of the camera. The virtual region is smaller than the physical region. The method also includes determining, using the image data, an occupancy of the virtual region and determining that the occupancy of the virtual region satisfies the occupancy threshold. In response to determining that the occupancy of the virtual region satisfies the occupancy threshold, the method also includes generating a notification to the subscriber device.

Abstract: A method of analysing a foodstuff sample using laser-induced breakdown spectroscopy, comprises: ashing the foodstuff sample to generate an ash residue; and forming the ash residue into a layered pellet based on: loading at least the portion of the ash residue into a die, loading a support material into the die as a layer covering a second surface of the portion of the ash residue subsequently to loading at least the portion of the ash residue into the die, and compressing the portion of the ash residue and the support material in the die to form the layered pellet, such that a first surface of the portion of the ash residue at least partially defines the first surface of the layered pellet and the portion of the ash residue is undiluted by the support material at least at the first surface of the portion of the ash residue.

Abstract: A LIBS analysis system comprises a focusing lens arrangement having a focal plane; a laser for propagating a laser beam through the focusing lens arrangement to be focused at the focal plane; a detector for generating an output that is proportional to an intensity of incident electromagnetic radiation that is incident on the detector; a translation mechanism configured to cause a relative movement of the sample holder and the focusing lens arrangement to vary a position of the focal plane along the optical path with respect to the sample holder; and a controller configured to automatically control the translation mechanism to cause the relative movement of the sample holder and the focusing lens arrangement to achieve an optimum position at which the focal plane and an analysis region of the upper surface intersecting the optical path are at or are close to coincidence.

Abstract: A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS) may include obtaining granular organic material, forming a portion of the granular organic material into a sample pellet, and searing the organic material. The searing may include searing only an exposed end surface of the sample pellet on which LIBS analysis is to be performed. The method may include pressing the seared sample pellet to consolidate the material comprising the seared end surface.

Abstract: Example implementations may relate to methods and systems for detecting an event in a physical region within a physical space. Accordingly, a computing system may receive from a subscriber device an indication of a virtual region within a virtual representation of the physical space such that the virtual region corresponds to the physical region. The system may also receive from the subscriber a trigger condition associated with the virtual region, where the trigger condition corresponds to a particular physical change in the physical region. The system may also receive sensor data from sensors in the physical space and a portion of the sensor data may be associated with the physical region. Based on the sensor data, the system may detect an event in the physical region that satisfies the trigger condition and may responsively provide to the subscriber a notification that indicates that the trigger condition has been satisfied.

Abstract: Systems are provided to emit, into an environment of interest, information in the form of modulated optical signals. These optical signals can be provided as illumination from a lighting fixture, display, or other source of environmental illumination. The optical signals can include codes or other information to facilitate location-specific operations of a device that is able to receive the optical signals. This can include receiving information about the location of a light emitter, security credentials or encryption keys, information about services that are available from building automation and/or conferencing systems, or other location-related information.
