Abstract: A transformerless bidirectional power converter is provided. The bidirectional power converter, in one implementation, interfaces split-phase ac, such as the 240 V ac commonly available in the United States, to dc terminals for charging and discharging the battery of an electrified vehicle. The bidirectional power converter enables and controls bidirectional power flow, to charge the battery from the ac power and to supply power from the battery to the ac, possibly with variable power factor.

Abstract: A cloud security control platform and method enforces security controls across multiple cloud environments, services and disparate teams while providing a frictionless “Permissions on Demand” mechanism for approvals and exceptions. In contrast to the prior art, security is evaluated on a permission by permission basis, with the default being that all permissions are denied and then only given to a particular identity on an as-needed basis. This approach reduces the security risks associated with the vast capabilities available in Public Cloud environments and permits an organization that uses the platform to grant access, approve exceptions and delegate approvals with the appropriate compliance.

Abstract: Inverters that interface dc and ac power sources and loads are provided. An example application is solar power systems, in which a dc source of power is an array of solar panels; the inverter converts the dc power supplied by these panels to ac power that is fed into the utility grid. Another example is battery energy storage; the inverter changes the dc power of the batteries into ac power that is fed into the grid, and also can convert (rectify) ac power from the grid for charging the batteries. In one embodiment, for example, an inverter comprises slow switches that generate a three-level ac voltage, followed by a plurality of fast-switching half-bridges that introduce high-frequency pulse-width modulation into a plurality of ac output voltages.

Abstract: A system and method of automated logistical vehicle registration and validation for remote monitoring. Cameras are deployed at the gate to a trucking logistics facility to record detailed information (e.g., license plate, identification info) on vehicles. Alternatively, vehicle and drive identification credentials can be provided by a mobile application from the driver. The cameras are connected to a data center hosting the automated logistical vehicle registration and validation system. Cameras are placed around the entry gate of a facility that takes snapshots of vehicles “checking in”. The system takes this info with assistance from artificial algorithms to read data and images (e.g., photos) to compare and verify the info. Recommendations are then sent to a guard to approve entry of the vehicle.

Abstract: A system and method of a threat detection system to automatically disseminate information being communicated over a communications channel during an event to help coordinate resources from the command center. By using speech processing algorithms along with artificial intelligence and natural language processing (NLP), a threat detection system can pull out key insights from the radio communication between the security personnel. Text in the radio frequencies can be recorded and transcribed and actionable alerts can be created.
