Abstract: A system can use a microphone to detect audio content from a content source, and analyze the audio content to determine whether the audio content corresponds to a respective portion of a stored content file. The system can then identify a response action correlated to the respective portion of the content file, and generate control commands to cause a robotic device to perform the response action.

Abstract: An apparatus balances a discharge in parallel battery configuration by having a battery pack (a) with a first battery system and a second battery system in parallel configuration, and a pulse width modulation device and (b) being interconnectable to a load. Each of the first and second battery systems has, in series and in order, a first voltage sensor, a resistor, a second voltage sensor, a string of battery cells, and a switching device. The first and second voltage sensor, in each battery system, measures an electrical current, used to calculate the voltage drop across each resistor. The voltage drop values for each battery system determine whether the pulse width modulation device alters or maintains the pulse width modulation applied to each battery system's switching device. By maintaining or altering the pulse width modulation applied to each switching device, the apparatus effectively balances the electrical current discharge from each battery system.

Abstract: The present disclosure provides systems and methods for a simulation environment that simulates hardware at a fiber level, a data plane level, a card level, and a chassis level. The simulation environment may be utilized in development and testing of complex, real time, embedded software systems, such as, for example, routers, switches, access devices, base stations, optical switches, optical add/drop multiplexers, Ethernet switches, and the like. In an exemplary embodiment, the simulation environment operates on one or more workstations utilizing a virtual machine to operate a virtualized module, line card, line blade, etc. Further, a plurality of virtual machines may operate together to operate a virtualized chassis forming a network element and with a plurality of virtualized chassis forming a network. Advantageously, the present invention provides state of the art data plane traffic and control plane simulation that reduces development time and cost while increasing design flexibility.

Abstract: The present disclosure describes methods and systems for the hierarchical mesh restoration of connections in an ASON or the like. These methods and systems provide a mesh restorable OTN server layer that carries an aggregate of mesh restorable SONET/SDH SNCs, without designating SONET/SDH/OTN hand-off ports or work/protect lines. Server layer SNCs are terminated on Virtual Trail Termination Points (VTTPs) on the NEs. These VTTPs maintain all of the attributes of physical Trail Termination Points (TTPs). The server routing protocol creates physical TTP interfaces at the server layer, and the server layer advertises bandwidth to the client layer routing protocol. A failure in the server layer results in the mesh restoration of an aggregate line, holding off the release of the individual client SNCs. Only when the server layer cannot restore are these individual client SNCs released.

Abstract: The present invention provides methods and systems for managing matrices of connections within digital switching fabrics. The methods and systems include means for defining one or more of sources and sinks in a matrix of connections as one or more of unidirectional connection termination points and novel unidirectional virtual connection points, where each of the unidirectional virtual connection points is a logical object that is maintained in software that defines connections between one or more of network resources and logical objects.
