An EMC test bench, includes an item of equipment under test to be loaded on board an aircraft, the item of equipment being subjected to EMC tests and delivering ARINC electrical interfaces as inputs and as output; an electrical interfaces device representative of an item of anti-lightning equipment and including an ARINC signals acquisition and/or generation card connected to the ARINC inputs and outputs of the item of equipment under test; a command and control rack for analyzing control signals originating from the electrical interfaces device including the ARINC signals acquisition and/or generation card, and a signals conversion system for protecting the command and control rack connected between the command and control rack and the electrical interfaces device.

There is provided a power supply receiver-transmitter device, a wireless power supply receiver, and a wireless power supply transmitter which allow wireless power supply transmission and wireless data transmission and reception, and improve the usability thereof. The wireless power supply receiver-transmitter device includes: a wireless power supply receiver (PR) including a power receiver unit (RU) and a first data transmitter/receiver unit (DRU); a wireless power supply transmitter (PT) including a power transmitter unit (TU); and a second data transmitter/receiver unit (DTU). The wireless power supply receiver (PR) wirelessly receives electric power transmitted from the wireless power supply transmitter (PT), and the first data transmitter/receiver unit (DRU) bidirectionally transmits and receives data to/from the second data transmitter/receiver units (DTU) through optical communications.

The present technology relates to a transmission apparatus, a transmission method, and a filter circuit that make it possible to transmit a signal with high quality, the signal including a plurality of signals having different speeds. The transmission apparatus includes a detection unit that detects each of a plurality of signals having different speeds from an input signal. Further, the transmission apparatus includes an output control unit that controls output of an output signal including the plurality of signals, on the basis of detection results of the plurality of signals by the detection unit. The present technology can be applied to, for example, a transmission apparatus that transmits a serial signal conforming to the USB 3.0 standards or a transmission apparatus that converts the serial signal described above into a millimeter-wave signal or an optical signal and sends and receives the signal.

Modular switchboard terminal block (10,20) for transmission of data signals (2) is provided, comprising a container (10a,20a) having, arranged inside it, a printed circuit (30) for processing the data signals, which has two opposite sides (30a,30b) in a transverse direction (Y-Y); connectors (11;21) for electrical connection to controlled/detection devices; and a rear end face provided with hook and spring means for mounting on a DIN switchboard rail (6).

An ambient light filter configured to filter ambient light noises from an optical current that is at least partially caused by an optical pulse sequence emitted by a light emitting device, can include: a sample and detection circuit configured to sample the optical current and to obtain a current component in a first mode, and to remove the current component from the optical current and to generate a detection signal in a second mode; a current amplifier configured to receive the detection signal, and to generate an amplified current signal; and a control circuit configured to switch the sample and detection circuit between the first and second modes, where the control circuit switches the sample and detection circuit to the first mode in at least one optical pulse gap, and switches the sample and detection circuit to the second mode when a next optical pulse arrives.

An apparatus and method for computer network security based on Free-Space Optical Interconnections (FSOI) for board-to-board information transmission. The addition of a controllable, interlocked shutter system creates air-gapped isolation of the boards, allowing for increased obfuscation, and enhanced security.

A cell site includes a tower, a multi-service terminal mounted to the tower and a base transceiver station in communication with the multi-service terminal. The multi-service terminal includes a housing and a plurality of adapters mounted to the housing. Each of the adapters includes an outer port accessible from outside the housing and an inner port accessible from inside the housing.

Example management closures (110) enable incoming optical and/or electrical signals to be connected to one or more subscribers (109) via an electrical distribution cable (102). Termination connections within the management closure (110) are connected to active electronic equipment (131) for modifying and/or enhancing the incoming signals. However, the connections between the central office (101), the active electronic equipment (131), and a subscriber (109) need not be made until the subscriber requests a service upgrade. Accordingly, the closure (110) allows for simple and low cost installation of the closure (110) before upgraded service is needed.
