Abstract: Systems and methods for controlling electric vehicle chargers using central control consoles for controlling and communicating with industrial equipment. The electric vehicle chargers operate as clients in a client-server configuration with a dedicated OCPP server. The OCPP server communicates with a control console using either of two communications paths—one path uses a direct HTTP connection with the control console. For this path, the control console operates as a web-enabled client. For the other path, multiple communications protocols are used and conversions between these protocols are effected using a conversion module and a MODBUS server. The MODBUS server communicates with the OCPP server. The MODBUS server also communicates with the control console by way of the conversion module and a control server. The control console is thereby able to control multiple pieces of industrial equipment along with the electric vehicle chargers without needing to be compliant with the OCPP protocol.

Abstract: The present application provides a method for bitumen froth treatment in the transition region between coalescence and agglomeration. The method involves separating diluted bitumen product from a bitumen froth mixture, comprising the bitumen, water and mineral solids, the method comprising: (a) combining the mixture with a solvent blend to obtain a combination having a ratio of said solvent blend to the bitumen of about 1.0-1.6 by mass, wherein said solvent blend comprises from 2.2-4.5 (±0.2) wt % aromatic solvent or from 70-80 (±10) wt % paraffinic solvent; (b) mixing the combination; and (c) separating the diluted bitumen product from the water and mineral solids.

Abstract: The present invention provides device system and a method for monitoring movements of mining conveyances in a mine shaft. One or more sensors that form part of the system may be installed directly on the mining conveyances. The sensors may be accelerometers and are for detecting movements on mining conveyances. The system may analyze the descent and ascent paths of the mining conveyances on guides by recording vertical, horizontal and transverse accelerations. The analysis may comprise associating the movements with position of the mining conveyances on the guides for identification of an anomaly at a specific position.

Abstract: A system and method for controlling microgrids composed of inverter-based distributed generation (IBDG) units. This includes a method using multiple IBDGs to inject impedance-modulated harmonic currents during fault conditions, with each IBDG injecting a unique, differentiable harmonic (i.e., non-fundamental) order from neighboring IBDGs. The method also involves using an inverse time-harmonic-current characteristic to detect faults by locally measuring the harmonic currents injected by IBDGs. A harmonic directional overcurrent relay is also used for fault detection.

Abstract: Thermal energy systems for managing, distribution and recovery of thermal energy. A single-pipe loop circulating a two-phase refrigerant is provided. The single-pipe loop is spread through the entire system and interconnects a plurality of local heat exchange stations, each having different thermal energy loads. A central circulation mechanism (CCM) is also provided for circulating the refrigerant for distribution of thermal energy within the system.
