This disclosure relates to a telecommunications method comprising concurrently maintaining different first and second Virtual Private Network, VPN, communications links between a VPN client and a VPN server.

An automation station can be used to repeatedly perform one or more tasks, typically at high speed. An automation station may include a plurality of servo motors that can be controlled according to a desired position. The automation station may further include one or more actuators that can be turned on/off, latched/unlatched, etc. The operation of the automation station requires that the operation of the servo motors and the actuators be coordinated in order to perform the desired actions. Configuring the automation station may be performed using a user interface that allows the operation of actuators to be linked to the control of the servo motors.

An optical media converter configured to convert an optical signal with a first modulation scheme to a second optical signal with a second modulation scheme. The optical media converter receives the optical signal and converts the optical signals into electrical signals corresponding to the optical signal with the first modulation scheme. A DSP in the optical media converter modifies the electrical signals to correspond with an optical signal with the second modulation scheme. The optical media converter generates the second optical signal with the second modulation scheme based on the modified electrical signals and transmits the second optical signal out of the optical media converter.

An optical module that includes two or more optical connection ports for transmitting optical signals to and from the optical module. The optical module receives a first optical signal through a first optical connection port and transmits a second optical signal through a second optical connection port. The second optical signal is generated based on a modulator in the optical module receiving an electrical signal from a DSP in the optical module.

The present disclosure describes an optical array for protecting optical systems. An optical device includes a first optical source, a second optical source, a third optical source, a first switch, a second switch, and a third switch. When the first optical source fails to produce a first optical signal, the third switch directs a second optical signal produced by the third optical source to the first switch and the first switch outputs the second optical signal. When the second optical source fails to produce a third optical signal, the third switch directs the second optical signal produced by the third optical source to the second switch and the second switch outputs the second optical signal.

A control system for a linear motor conveyor includes a programmable logic controller capable of determining shuttle trajectories of shuttles moving on the track of the linear motor and a computing device that provides different motion control methods for controlling movement of the plurality of shuttles. The different methods include an internal trajectory control that determines the shuttle trajectories and then determines the control data necessary to provide the determined trajectories and a 3^rd party trajectory control that receives the shuttle trajectories from the PLC and then determines the control data necessary to provide the received trajectories.

A linear motor conveyor system (100) uses a central controller (108) to determine trajectories (114a, 114b) of shuttles (106a, 106b) traveling on a conveyor track (102). The trajectories are provided to respective controllers in each section (104a, ..., 104h) of the conveyor track in order to determine and control the coil currents used to move the shuttles. A time synchronization process is used to ensure tight temporal synchronization across the different track sections

The wavelength selection circuit comprising a first waveguide coupled to a first gain chip of the at least two gain chips, a second waveguide coupled to a second gain chip of the at least two gain chips, a first wavelength selective photonic ring resonator optically coupled to the first waveguide, a second wavelength selective photonic ring resonator optically coupled to second waveguide, a third waveguide optically coupled to the first wavelength selective photonic ring resonator and the second wavelength selective photonic ring resonator; and a control circuit. The control circuit is configured to apply a first current to the first gain chip to bias the first gain chip, tune the first wavelength selective photonic ring resonator to a target wavelength, and tune the second wavelength selective ring resonator off-resonance.

An advanced optical device featuring a substrate with a receiver photonic integrated circuit (PIC) and a transimpedance amplifier (TIA) is disclosed. The PIC is mechanically coupled to the substrate, while the TIA is mounted to the substrate and electrically connected to the PIC. One configuration includes a receiver die flip-chip bonded to a TIA die using copper pillar bumps, optimizing space with the PIC having a smaller footprint than the TIA. A fiber array is precisely aligned and attached to the PIC using epoxy bonding, aided by alignment marks indicating spot-size converters (SSCs). The PIC incudes multiple photodetectors and waveguides, enhancing light guidance and conversion. The manufacturing process involves a chip-on-wafer technique, forming a dam for epoxy application, and precise alignment of fiducials to the fiber array. The method also includes molding, forming through-mold vias, and redistributing electrical connections, ensuring efficient signal processing and integration without wire bonding.
