Abstract: A sensor assembly is positioned on an exterior of a tank to measure a fluid level within the tank. The tank is modified to include a surface feature and the sensor assembly is slotted within that surface feature. The sensor assembly includes a sensor device and a control circuit configured to drive the sensor device and evaluate readings to determine the fluid level. The sensor assembly further includes a communications interface to enable communication with a management system via a communications network. The management system can store information (e.g. fill status) related to the tank and additionally communicate with vendors or end users to coordinate resupply.

Abstract: A magnetic levitation system for sliding door and window, includes at least a movable module for the lower part of the sliding door and window which includes one or more permanent magnets; several fixed modules for the lower part of the frame of the sliding door and window, which includes one or more electromagnets to produce a variable repulsive magnetic field of the magnetic field of said magnets of the movable module. It has the advantage of eliminating the friction, mechanical wear and noise associated to the sliding, allowing, when deactivated, a greater air and water tightness and terminal and acoustic insulation, allowing the electromagnetic closure or locking of the door and window, increasing the security, and as is a modular system its operation and construction are simpler and more economical.
