Abstract: Physical object boundary detection techniques and systems are described. In one example, an augmented reality module generates three dimensional point cloud data. This data describes depths at respective points within a physical environment that includes the physical object. A physical object boundary detection module is then employed to filter the point cloud data by removing points that correspond to a ground plane. The module then performs a nearest neighbor search to locate a subset of the points within the filtered point cloud data that correspond to the physical object. Based on this subset, the module projects the subset of points onto the ground plane to generate a two-dimensional boundary. The two-dimensional boundary is then extruded based on a height determined from a point having a maximum distance from the ground plane from the filtered cloud point data.

A MEMS teeter-totter switch can include a beam coupled to an anchor on a substrate and two control electrodes, disposed on a surface of the substrate. A control circuit may include an isolator that provides an isolated activation voltage to a voltage supply and control circuit.

The input voltage is applied on the beam with respect to a second reference voltage different from the first reference voltage.

Abstract: Systems and methods are disclosed for facilitating the advancement of treatment devices within the neurovascular system of a patient. The method includes advancing an outer device, while in a manoeuvrable configuration, to a first location and actively bracing the outer device in a braced configuration, such that the position of the outer device is substantially maintained while one or more inner devices or treatment devices are advanced further into the neurovascular system. Active bracing features limit longitudinal movement of the devices, thereby reducing the risk of one or more devices slipping or prolapsing out of a target blood vessel within tortuous anatomy.

Abstract: A water treatment system and method. Influent water produced from an oil and gas production or the like is circulated in a multistage unit where the water is treated by degassing the water by saturating the water with air, stripping volatile compounds from the water, evaporating non-aqueous phase liquid petroleum from the water, repeatedly stripping and equilibrating inorganic carbons in the water, subliming semi-solids from the water, and breaking colloids in the water using continuous cavitation. Water from the multistage unit is clarified through floatation and sedimentation and biological material in the water is inactivated using irradiation. Water is then filtered before being provided as treated water for an application specific process such as electro desalination reversal, fracking reuse, or other wastewater recovery.

Abstract: A heat spreader composed of a hexagonal boron carbon nitride (hBCN) thin film, can be a major solution for the ever-increasing problem of overheating electronic devices. This heat spreader can dissipate heat away from hotspots on electronic devices, unlocking additional processing power. Our method is able to effectively tune the thermal and electrical conductivity of our films by modulating the carbon content of the precursor used in a chemical vapor deposition (CVD) process. Using this method, we can generate a heat spreader that is electrically insulative, so it will not have the potential to create shorts, like graphene and metals. Additionally, we can maximize the thermal conductivity, obtaining a value of 460±149 W/m·K, which rivals or even surpasses hexagonal boron nitride (hBN). As our precursor material is 10 times cheaper than the most common hBN precursor, this is an economical alternative to hBN for heat spreader applications.

Complex event processing (CEP) operating on event records from various data streams can operate by storing the streamed event record data in a database, and then querying the data to perform a data transformation.

The resulting transformed data can then be provided by the serverless architecture to the CEP for direct access of the data most needed by the CEP.
