Abstract: The present disclosure describes an optical routing circuit (ORC) which may be used to route an input optical signal to one or more optical output channels of the ORC. The ORC comprises a network of nodes for carrying out the task of optical signal routing. The nodes may be controlled by a node control system through electrical node control channels. The ORC may simplify the electrical interface between the nodes and the node control system by sharing an electrical node control channel among a subset of nodes of the ORC. Nodes of the ORC may transmit electrical signals between the nodes. The present disclosure also describes a node which may be used to construct the ORC and a method of routing an optical signal. The present disclosure may enable a large ORC with many nodes to be practically implemented.

Abstract: Microbial disinfection is performed using continuous or intermittent lighting using one or more narrow wavelength light sources. The light sources illuminate with narrow wavelength characteristics. The lighting provides a sufficiently high intensity for rapid microbial disinfection process, while reducing the average energy consumption for microbial disinfection during the microbial disinfection process by targeting multiple cellular sites along different inactivation pathways.

Abstract: The present invention relates to a coherent detection array and methods of multiplexing for signal readout of the coherent detection array. The coherent detection array may be implemented on a photonic integrated circuit (PIC). It may comprise a plurality of coherent detection units coupling with connecting waveguides and electrical conducting paths, wherein the electrical conducting paths may manifest as readout channels for multiplexing electrical signals. The detection units may be configured to include free-space-to-waveguide couplers, optical couplers, and photodetectors. The coherent detection array enables multiplexing methods that may leverage extra degrees of freedom of the coherent detection array. These methods may include those enabled by the local oscillator and those related to the properties and responses of the components of the PIC-based detection array.

Abstract: A power supply aging system and a load balance control method. The power supply aging system includes: a system share supply unit (201) for producing a DC voltage for the need of the system constant current balance, a renewable load unit (202) for converting a low DC voltage outputted by a unit under test (200) to a high DC voltage, a DC to AC converting unit (203) for converting the high DC voltage to the AC voltage needed by the unit under test. The AC voltage is transmitted to the unit under test through a renewable AC bus. The system does not need any isolation transformer or the authorization from power supplying enterprises. The system can balance the DC load sharing, reduce the cost, improve the efficiency of electrical energy feedback and reduce the energy waste.

Abstract: An integrated shipping scheme enables users of a third-party payment service to facilitate shipment of packages via a shipping vendor. Web pages corresponding to a web site hosted by the third-party payment service enable a sender to enter ship to: information, while ship from: information may be automatically gathered or manually entered by the sender. The sender is also enabled to enter shipment options, such as package size and weight. Corresponding shipping information is generated and sent “behind the scenes” to a selected shipping vendor. The shipping vendor processes the shipping information, and returns shipment data, including data to generate a shipping label. A web page containing the shipping label is then generated and served to a client operated by the sender, enabling the shipping label to be printed out.
