Abstract: An electronic device is for monitoring the visible spectrum of a specified sample with agile monitoring techniques. The device may seek to decouple the sensor from static measurements and allow for dynamic measurements in systems where the response is not wide sense stationary, allowing the end user to aggregate multiple data points or moments in summarizing the health of a larger system. In aquacultures, the device may be capable of functioning as a floating buoy where a chemical sensor with a color response can note readings at multiple points within a stream or water body.

Abstract: Sensors, devices, systems, devices, and methods for providing wireless modular self-contained units with battery power supply that can use radar, ultrasonic, and IR measuring techniques and sensors for directional detection of impeding objects, persons, or moving targets, and can be used with mobile smart phones and the like. The modular sensor units can be used as a displacement and motion measurement sensor for point of reference measurement applications. The displacement sensing method can use radar, ultrasonic, and IR measuring techniques for directional detection of impeding objects, persons, or moving targets. Upon the detection of the said target, algorithms make use of the direction, angle of ascent, and speed to provide real time position data represented in discrete format.

Abstract: Systems, devices, and methods for smart sensors/monitors and for a smart asset tag solution for tracking assets along the distribution cycle. These solutions are an extension of using various radio frequency technologies to locate the whereabouts of goods/assets with the use of additional sensors to provide granular knowledge about the asset above and beyond location. The technology can differentiate when the asset is being transported, stationary, or other inspection points along the distribution cycle of the cargo. Other applications of smart sensors, monitors, systems, devices and methods can be used to monitor fluid-leak detection or fluid-level detection from an electro-mechanical device, such as water pump, as well as fluid/water such as from a water pump, and for measuring and monitoring condensation levels in a pan under an HVAC system, and the like.

The technology seeks to differentiate when the asset is being transported, stationary, or other inspection points along the distribution cycle of the cargo. To achieve this goal, a combination of RF sensors/transceivers for the real-time location along with other sensor to include IMUS, proximity sensors, and ambient light and temperature sensors deduce information about the asset over and beyond just the location. The combination of data will be combined to provide a real-time touchpoint for cloud based tracking above and beyond the current state-of-the-art in internet-of-things asset tracking.

Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.
