Abstract: An electric vehicle (EV) charging system is described herein. The EV charging system may be configured to determine if a component in the EV charging system is operating properly based upon current usage. For example, an EV charging station controller may measure a current corresponding to an input to an EV charging station. The EV charging station controller may further measure currents of reference components in the EV charging station, and then use the measured currents to determine if a component in the EV charging station is operating properly. In some examples, the component is a heating, ventilation, and air conditioning (HVAC) component in an EV charging station because it is particularly useful to know the operational status of an HVAC in EV charging systems (e.g., to ensure that the components charging the EV are the correct temperature).

Abstract: An inspection system and an inspection method of a bare circuit board are provided. The inspection system is used for inspecting a bare circuit board. The bare circuit board includes a chip pad and an antenna. The inspection system includes an adapter board, a test device and a measure device. The adapter board includes a chip and a contact structure. The chip is electrically connected to the contact structure. The contact structure touches the chip pad so that the chip is electrically connected to the chip pad. The test device includes a transceiver antenna. The test device and the bare circuit board separate. The measure device is electrically connected to the chip or the transceiver antenna.

Abstract: A feedback-based adaptive network is described wherein at least a portion of the network elements report operating information relating to network conditions to a centralized data store. The information which is reported to the data store is analyzed by a policy engine, and updated control information may be generated. The updated control information may be fed back to selected network elements to thereby affect operation of the selected elements. In this way, the dynamic and automatic feedback control of network elements is provided. Events relating to changing conditions in the network may also be reported to selected elements. Additionally the adaptive, feedback-based network may include a network quality monitoring system for evaluating performance characteristics or other aspects of the network.

Abstract: A feedback-based adaptive network is described wherein at least a portion of the network elements report operating information relating to network conditions to a centralized data store. The information is analyzed by a policy engine which includes a plurality of specific plug-in policies for analyzing selected information from the data store and for computing updated control information which is fed back to affect operation of selected network elements. In this way the dynamic and automatic feedback control of network elements is provided to allow the network to adapt to events relating to changing conditions. The adaptive, feedback based network may include a network quality monitoring system for evaluating performance characteristics based upon predetermined standard or criteria.

Abstract: A method and system for role-based access control enforced by an Operating System filesystem are provided. A file representing a resource is created and stored in the Operating System filesystem. A user requests access to the resource and provides user-identifying information and a resource identifier. An access identifier is created based on the user-identifying information and the resource identifier, and is formatted as the file attribute used by the Operating System to manage file access. A system call to the Operating System is made to perform an operation on the file representing the resource, where the system call uses the access identifier to gain access to the file. The user is granted access to the resource only if the operating system successfully performs the operation on the file representing the resource.

Abstract: A feedback-based adaptive network is described wherein at least a portion of the network elements report operating information relating to network conditions to a centralized data store. The information which is reported to the data store is analyzed by a policy engine which includes a plurality of application specific plug-in policies for analyzing selected information from the data store and for computing updated control information based upon the analysis of the information. The updated control information is fed back to selected network elements to thereby affect operation of the selected elements. Typically, when the operation of a network element has been affected, its corresponding operating information will change. The new or changed network element operating information is then reported to the data store and analyzed by the policy engine. The policy engine may then generate new or updated control information for affecting the operation of selected elements in the network.

Abstract: A method of automatically subscribing a network device to a plurality of events applicable to a logical group, of which the network device is a member, is disclosed. The method involves first creating and storing a mapping that associates a plurality of network devices with a logical group and that associates the logical group with one or more events that can pass over an event bus to which the network device is logically coupled. At runtime, a device identifier of one of the network devices in the logical group is received, an event identifier of an event that is among the one or more events that are in the second mapping is received. Based on the mapping, the method causes the network device to receive all events that are associated in the mapping with the logical group that includes the network device.
