Abstract: PURPOSE: To enable the selection of either built-in DAA or external DAA and to miniaturize MODEM board. CONSTITUTION: A hybrid circuit 14 connected to a MODEM circuit 12 and a built-in DAA 24 are mounted on a MODEM board. These hybrid circuit 14 and the built-in DAA 24 are respectively connected to an interface connector 18. When a plug subcard 26 equipped with a MiniDin connector 28 is inserted into this interface connector 18, an external DAA 32 and the MODEM circuit 12 are connected through the hybrid circuit 14 on the MODEM board. When another plug subcard equipped with an RJ11 connector is inserted, the built-in DAA 24 is connected through the hybrid circuit 14 to the MODEM circuit 12. Thus, communication due to analog signals corresponding to either the built-in DAA 24 or the external DAA 32 is allowed.

Abstract: PROBLEM TO BE SOLVED: To provide a control method for radio LAN module capable of suppressing consumption power. SOLUTION: The control method comprises a step S201 of scanning an access point, a step S205 of setting a scanning time interval T up to the next scanning to t1 if communication with the access point is available, and a step S215 of setting the time interval T to t2 longer than t1 if the communication is not available. The control method further comprises a step S207 of determining whether power is supplied from an AC power supply or not if the communication is available, a step S209 of setting drive mode of the radio LAN module to a normal mode if it is determined that the power is supplied from the AC power supply, a step S210 of setting a power saving mode if not from the AC power supply, and a step S217 of setting the drive mode to a deep sleep mode if the communication is not available.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption when a computer with a mini PCI card or a device corresponding to the mini PCI card inserted thereinto is in an inactive state. SOLUTION: An I/O bridge 21 for outputting inactive information about whether or not a computer system is in an inactive state and a Vaux off at sleep resister 42d holding information about whether or not to feed auxiliary power VccAUX to a mini PCI device 60 when the computer system is inactive, are provided. When a signal from the I/O bridge 21 is L and a signal from the register 42d is L, the feeding of the auxiliary power VccAUX is stopped from a DC/DC converter 55.

Abstract: PROBLEM TO BE SOLVED: To save the power of an audio amplifier by providing an audio amplifier amplifyingly processing audio signals from peripheral equipments and an AND gate which receives mute signals from peripheral equipments of one or more and which outputs a control signal reducing the power of the amplifier when all mute signal are in mute states while ANDing the mute signals. SOLUTION: Mute signals from, for example, five sets of peripheral equipments having mute signal outputs indicating mute states in which audio signals are not outputted are ANDed in an AND gate 52 and when all peripheral equipments are in mute states, the assert signal of the gate 52 indicates that an audio amplifier 51 is unused. The output of the AND gate 52 is inputted to the power saving control pin of the audio amplifier 51. When the input is in a negated state, the amplifier 51 performs an amplifying procession and when the input is in an asserted state, the amplifier is in a power saving state and it is made impossible to perform the amplifying processing of audio signals and, then, the lowering of power consumption is made possible.

Abstract: PROBLEM TO BE SOLVED: To provide a system in which security can be strengthened in a wireless LAN. SOLUTION: In a network security system, clients 10a-10e are connected to the LAN by radio transmission to search nearby access points (AP). The list of the acquired access points as a result of the search is sent to a controller 20. In the controller 20, the list of access points registered beforehand is compared with the lists sent from the respective clients 10a-10e and detects unregistered access points.
