Abstract: A communication device includes a connector inserted into a first device, a communication circuit which performs wireless communication with a second device, and a processing circuit. The processing circuit is programmed to communicate with the first device via the connector to control the communication circuit, wherein the processing circuit is configured to execute generating a first signal representing that the connector is pulled out from the first device when the processing circuit detects that the connector is pulled out from the first device, and transmitting the first signal to the second device by controlling the communication circuit.

Abstract: A processor controlling access to a memory includes: a physical layer controller executing data access to the memory; a memory controller accepting an access request to the memory from a plurality of bus masters and causing the physical layer controller to execute the access request; and a CPU. The CPU shifts the memory controller into a busy state to accept the access request and stand by for execution, when a condition to turn the memory into a power-saving state is satisfied. The CPU executes control to turn the memory into the power-saving state, with the memory controller being in the busy state.

Abstract: A projector that is allowed to belong to a multi-projection system that projects an image on a projection surface, the image formed of a plurality of partial images including a first partial image, a second partial image, and a third partial image, includes a projection section that projects the third partial image on the projection surface and an adjustment instruction section that transmits, to a first projector that projects the first partial image, a first adjustment instruction of adjusting the projection area of the first partial image based on the projection area of the third partial image and transmits, to a second projector that projects the second partial image after transmitting the first adjustment instruction, a second adjustment instruction of adjusting the projection area of the second partial image based on the projection area of the first partial image.

Abstract: A power supply cable includes: an even number of electric wires that each includes a flexible cooling pipe, an electric conductor that surrounds the cooling pipe, and an insulator that surrounds the electric conductor; a filling disposed around the even number of electric wires; and a sheath that covers the even number of the electric wires and the filling. The electric conductor is a plurality of conductor wires wound around the cooling pipe.

Abstract: A power supply cable includes: a first communication cord that includes a first signal line and a cover that accommodates the first signal line; a plurality of power lines each including a cooling tube, a conductor that surrounds the cooling tube, and an insulator that surrounds the conductor; and a sheath that accommodates the first communication cord and the plurality of power lines. In a cross-sectional view, the plurality of power lines surround the first communication cord.

Abstract: A power supply cable includes: a plurality of power lines each including a cooling pipe and a conductor that surrounds the cooling pipe. Two or more of the power lines have a same polarity. The cooling pipes of two or more power lines with the same polarity are connected to each other at a first end of the power supply cable. The power supply cable further includes a first communication cord including a first signal line and a coating that accommodates the first signal line.
