Abstract: Provided is an optical communication connector that includes a control unit (42). The control unit (42) controls alignment of a ferrule (170) and a lens (162). The ferrule (170) is to fix a fiber (23). The control unit (42) varies a shape of a shape variation member (21) on the basis of a communication quality of light entering the fiber (23) via the lens (162) to control the alignment.

Abstract: In a case where a main stream and a control signal are transmitted in parallel between two devices, transmission of the main stream is continued without interruption of the transmission of the main stream even in a case where communication quality of the control signal is deteriorated. Provided is a transmission control device including an information acquisition unit configured to acquire a channel change request transmitted from a reception device in a case where communication quality of a control signal transmitted through a first channel and received by the reception device being poorer than first quality has been detected, and a transmission control unit configured to start transmission of the control signal to the reception device through a second channel different from the first channel in a case where the channel change request has been acquired, in which the transmission control unit stops transmission of the control signal through the first channel in a case where a predetermined condition has been satisfied since the start of transmission of the control signal through the second channel.

Abstract: It is possible to preferably transmit a command received from an external network to a corresponding device in an internal network. A command transmitted from a device on a first network is received. Transmitter information and receiver information are added to the received command, and the command is sent to a command transmission path of a second network. The transmitter information added to the command is rewritten from information regarding a proxy device to information regarding a device capable of transmitting the command when the proxy device is a device incapable of transmitting the received command.

Abstract: It is made possible to consume current without adversely affecting the others. A cable is connected between a first device and a second device. A power line that supplies a current from the first device to the second device, and a current consumption unit that receives supply of a current from the first device through the power line, are included. A detection unit that detects that the second device is in the operating state, and a control unit that cancels a stop state of current consumption of the current consumption unit in response to the detection information, are further included.

Abstract: Laser hazard at disconnection can be prevented with a simple structure. A tubular connector exterior, and a block that is incorporated on one end side of the connector exterior and on which a light emission portion or a light incident portion is mounted toward the other end side are provided. The light emission portion or the light incident portion is mounted on the block so that the optical axis direction thereof is tilted relative to the longitudinal direction of the connector exterior. The light emission portion is a lens through which light output from a light transmission path is collimated and emitted. At least part of the collimated light emitted through the lens is incident on a light diffusion portion provided inside the connector exterior.

Abstract: A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel. A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.

Abstract: [Abstract] [Object] To provide a connector, a connector set, a cable, and an electronic apparatus that prevent light from an optical transmission path from being directly emitted to the outside of an optical connector during non-optical coupling.
[Solving Means] A connector includes an optical component and a movable member. The optical component emits light. Light from the optical component is incident upon the movable member and the movable member is movable between a first state taken during non-fitting to a counterpart connector and a second state taken during fitting to the counterpart connector. Incident light incident upon the movable member from the optical component is, in the first state, attenuated and emitted to an outside such that power of the light is lower than power of the light when the movable member is held in the second state.

Abstract: Damaging a device that is not compatible with a functional extension is to be avoided. A signal is transmitted to an external device through a transmission channel. A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.

Abstract: An optical axis or a diameter of light of even a light beam having a non-uniform intensity distribution is stably obtained. An outer shape of a range of a light intensity having a specified ratio with respect to a total light intensity on a cross-section of a light beam is obtained. An approximate circle is obtained from this outer shape. For example, the approximate circle is calculated by using the least-squares method. An optical axis and/or a diameter of light of the light beam is obtained on the basis of this approximate circle.
