Abstract: A position estimation system includes a beacon transmitter that transmits a beacon signal, a mobile station that receives the beacon signal from the beacon transmitter and transmits positioning data including ID information of the received beacon signal, and a position information server that estimates a position of the mobile station based on the positioning data transmitted from the mobile station, in which the mobile station includes a plurality of transmission means, and switches the transmission means for transmitting the positioning data based on the received beacon signal.

Abstract: A device control apparatus according to an embodiment includes a monitoring unit, a first processing unit, and a second processing unit. The monitoring unit monitors a state of voltage supply from a battery. When the start of the voltage supply is detected, the first processing unit starts the voltage supply to some devices, operates in a first operation mode, and executes a resume process of the devices. When the resume process is completed, the second processing unit starts the voltage supply to devices other than some devices, initializes states of the devices, and operates in a second operation mode in which consumption power is larger than consumption power of the first operation mode.

Abstract: An information recording/reproducing apparatus includes a reproduction unit, an operation unit, a storage unit, and a control unit. The reproduction unit reads information recorded in a recording medium. The operation unit instructs the reproduction unit to eject the recording medium. The storage unit stores the information read by there production unit therein. When the recording medium is loaded into the reproduction unit, the control unit controls the reproduction unit to read the information and controls the storage unit to store the information read by there production unit therein automatically. When the operation unit instructs the reproduction unit to eject the recording medium during the storage unit being storing the information read, the control unit informs a user that the storage unit is storing the information read.
