Abstract: An apparatus for preventing malfunctions of a touchpad disposed near an antenna is provided. An NFC coil is disposed underneath a touchpad. In NFC, an NFC card approaches the surface of the touchpad. A touch controller sets the detection sensitivity of a finger to a reference value when an NFC module does not emit alternating magnetic fluxes. The touch controller reduces the detection sensitivity at the timing when the NFC coil starts the emission of the alternating magnetic fluxes. The touch controller returns the detection sensitivity to the reference value at the timing when the NFC coil stops the emission of the alternating magnetic fluxes. The NFC module directly transmits a signal with which the touch controller changes the detection sensitivity to the touch controller through a hardware line.

Abstract: There are provided methods and arrangements for communication in which, even in a case where an antenna that is not correctly connected is present in a wireless module provided with a plurality of antennas, high-performance data communication can be performed without using such antennas. RSSI values are detected from a plurality of receiving circuits of a wireless module, respectively, and a computer judges whether or not there is a significant difference between a first RSSI value detected from one receiving circuit and a second RSSI value detected from another receiving circuit. In a case where it is judged that there is the significant difference, the computer recognizes that the receiving circuit from which a larger RSSI value has been detected is connected to an antenna and the receiving circuit from which a smaller RSSI value has been detected is not connected to the antenna, and the receiving circuit recognized to be unconnected to the antenna is set to operation stop.

Abstract: A computer and a method for enabling remote communication to a computer operating in a power-saving mode in which one or more one power sources to internal devices are disabled. The computer is equipped with a power management control circuit which is responsive to a first signal indicating that a device used to receive remote communication is to receive power while operating in a power-saving mode. In the event that a remote communications is detected which is targeted for the computer, a second signal is asserted by the remote communications device. The power management control circuit responds by exiting the power-saving mode and restoring power to the disabled power source to enable the computer to process the incoming communication. The remote communication may be through a wireless source such as a radio frequency channel or through a fixed wire such as a telephone network or LAN.

Abstract: When the computer is powered on, a POST program is executed, and in the setting for enabling a security function, an RFID chip 33 makes Removal Detect Enable a high level and outputs it to the control side of an analog switch 67 and one input of a NAND element 63. The removal of an RF antenna 37 causes a first short-circuit element 36 to be disconnected for shutting off a terminal 71 and a terminal 73, and an INTR signal for prohibiting the keyboard input is outputted by the high-level signal of the element 63 to prohibit access to the computer. If the RF antenna is removed while the power is off, the analog switch 67 is disconnected and the power supplied from a lithium battery to a CMOS memory 50 is shut off, whereby access to the computer can be prohibited.

Abstract: A technique for prohibiting access to a computer having a security function when a security device is illegally removed from the computer. The security device is a hardware component that constitutes a part of a security function for a computer. When the security device is illegally removed from the computer, access to the computer is prohibited. Data indicating that the security device is attached to the computer are stored in a nonvolatile memory. Then, when a specific event, such as a power-ON event, is used as a trigger, the procedure for prohibiting the access to the computer is initiated. Following this, based on the data stored in the memory, it is detected that the security device was once attached to the computer and that it has now been removed. If currently the security device is not attached to the computer, although it was attached before, the access to the computer is prohibited.
