摘要： A connector is made connectable with a DC power source by using a transmission line. The transmission line has a power source line and a signal line. A switch disconnects a signal line or makes the signal line connectable to a reference potential line. A controller monitors the potential of the signal line, detects reconnection of the signal line on the basis of the potential and then boots a host system.

摘要： Systems that detect a positional relationship between an informal processing device and an external keyboard are disclosed. A system includes an external keyboard including a first communication unit, an incoming coil disposed inside thereof, and an input controller configured to control the first communication unit to transmit operating information indicating an input operation from a user, information processing device including a second communication unit configured to communicate with the first communication unit, a planar portion on which the keyboard is mountable, and a feeding coil disposed below the planar portion, the feeding coil configured to supply electricity to the incoming coil by an electromagnetically induced coupling, and a position detector configured to detect a positional relationship between the planar portion and the keyboard based on a coupling strength of the electromagnetically induced coupling between the feeding coil and the incoming coil. Similar apparatus and methods are also provided.

摘要： A connector includes a terminal having one end soldered to a substrate; an insulating member that supports the terminal; a metal case that covers a part of the insulating member and the terminal; and a metal shield that is spot-welded to the case at several positions and covers an exposed part of the insulating member. The shield includes: an upper shielding part that covers the upper plate of the case; and an inner shielding part that bends from the end of the upper shielding part and reaches the mounting face of the substrate or a position close to the mounting face and covers the substrate-inward lateral face of the insulating member. The inner shielding part has ground posts.
