Abstract: A positioning system includes a detector arranged in a terminal to detect a dynamic physical quantity generated at the terminal, and a position calculator that obtains a position of the terminal when the terminal is moved relative to a communication peer. The detector includes a direction detector that detects a movement direction of the terminal, and a movement change amount detector that detects a movement change amount of the terminal.

Abstract: This key security device is used together with a first terminal which may be a mobile phone with high functionality and a second terminal which may be an electronic key. The key security device is provided with: a location information acquiring unit which acquires location information about the first terminal from a global positioning system (GPS) receiver of the first terminal; a level setting unit which sets an alert level according to the acquired location information; and a security guard processor which sets a location determination parameter value according to the alert level, monitors the distance between the first terminal and the second terminal through communication between the first terminal and the second terminal according to the alert level and the location determination parameter, and executes a security guard processing of the second terminal according to the result of the monitoring.

Abstract: An electronic key system includes a device that is subject to operation, an electronic key that is authenticatable by the device, and a wearable device that is wearable by a user. The wearable device is capable of recognizing an intention communication action of the user. The device authenticates the electronic key and permits a device operation associated with the intention communication action of the user recognized by the wearable device.

Abstract: A module includes a housing including a battery housing portion that houses a battery, an operation accepting unit including a first board including accepting means that accepts an operation and is arranged on the first board, the first board being attached to the housing, and a second board housed within the battery housing portion along with the battery. A control circuit electrically connected to the accepting means is arranged on the second board.

Abstract: An electronic key includes a housing including a battery housing portion that houses a battery, the battery housing portion being provided in the housing, a battery terminal, arranged within the battery housing portion, that makes contact with one electrode of the battery housed within the battery housing portion, and a board, arranged within the battery housing portion, including a first conductive portion that makes contact with the battery terminal and is electrically connected to the one electrode of the battery via the battery terminal, and a second conductive portion that makes contact with and is electrically connected to another electrode of the battery.

Abstract: A circuit board structure includes a test terminal. The circuit board structure includes and interface circuit board and a functional circuit board. The interface circuit board includes common test terminals shared by different functional circuit boards. The functional circuit board realizes a product function. The functional circuit board is selected from a plurality of functional circuit boards respectively realizing different product functions. Circuit components required for each product function are mounted on the corresponding functional circuit board.

Abstract: A circuit board includes a circuit board pattern forming a part of an electronic circuit and including a mounting pattern group on which a receiving means for receiving an operation can be mounted. The electronic circuit is established even when the receiving means is mounted on any mounting pattern of the mounting pattern group.

Abstract: A switch packing includes a switch mechanism part disposed between an operation button and a switch element, and configured to be elastically deformed by pushing the operation button so as to have the switch element change to a first state and provide an operational feeling via the operation button, and a sealing part configured to prevent penetration of a liquid. The switch mechanism part and the sealing part are integrated with each other.

Abstract: A switch device includes a lid arranged between a tactile switch, which is arranged on a substrate, and an operation button, which is coupled to a retainer so that the operation button can be pushed. The lid includes an opening at a location corresponding to the tactile switch. A lower surface of the elastic member is coupled to a surface of the lid. The operation button, when pushed, activates the tactile switch with an elastic member. The operation body, when released from the pushed state, deactivates the tactile switch as a reaction force of the elastic member returns the operation button to an initial position. The switch device includes a projection that supports the operation button. The projection is formed on an upper surface of the elastic member at a location corresponding to the surface of the lid.
