Abstract: An electrolyte solution containing a compound (1) represented by the formula (1), (wherein R101 and R102 are each individually a substituent such as a C1-C7 alkyl group, and the substituent optionally contains at least one divalent to hexavalent hetero atom in a structure or optionally has a structure obtained by replacing at least one hydrogen atom by a fluorine atom or a C0-C7 functional group) and at least one compound (11) selected from compounds such as a compound represented by formula (11-1) (wherein R111 and R112 are the same as or different from each other and are each a hydrogen atom or the like, and R113 is an alkyl group free from a fluorine atom or the like):

Abstract: A data transmission system using a human body as a signal transmission path includes a transmitter and a receiver. The transmitter uses a pair of electrodes which are held in close proximity to the skin of the human body. The transmitter transmits data to the receiver through the signal transmission path partly extending through the human body when a user carrying the transmitter touches a touch electrode of the receiver. The electrodes are integrated into a garment worn by the user in such a manner that the electrodes are kept in a closely facing relation to the skin of the user, thereby establishing the electrical path extending through the human body. With the integration of the two electrodes into the garment, the user wearing the garment as an everyday clothes or uniform can be easy and convenient to carry the transmitter for successful transmission of the data.

Abstract: Touch-responsive data transmission system for elongating transceiver battery life and assuring one-touch data transmission includes a first transceiver worn on user and a second transceiver connected to equipment utilizing first transceiver data. User contacts first transceiver signal and ground electrodes and touches a second transceiver touch electrode to establish a signal path through user. First transceiver includes a detector for detecting a start signal from the second transceiver signal electrode. Second transceiver includes a generator for generating the start signal upon touching the touch electrode. Receiving the start signal, circuit elements responsible for data transmission are battery-energized to start data transmission from first to second transceivers. Circuit elements responsible for transmitting data remain deenergized until user touches the second transceiver touch electrode to save energy during non-operation and prolong first transceiver battery life.

Abstract: A communication system includes a transmitting device, a receiving device having receiving device for receiving data transmitted by said transmitting device and managing device for managing received data, detecting device for detecting whether or not communication of data between said transmitting device and said receiving device is permitted, said detecting device being provided with at least one of said transmitting device and said receiving device, wherein when said detecting device detects a fact that communication of data is permitted, said transmitting device starts transmitting data to said receiving device.
