Publication number: 20040038707Abstract: A power management method and apparatus for a wireless LAN module in a computer system may include a communication sensitivity checking unit for checking a communication sensitivity of a wireless communications channel. If a communications sensitivity is lower than a desired value, a power mode of the wireless LAN module is changed into a sleep mode for a predetermined period of time. After the delay period expires, the wireless LAN module is switched back into a normal mode, and the communications sensitivity is checked again. If the communications sensitivity is acceptable, a data checking unit checks to determine whether there is data to be transmitted/received by the wireless LAN module. If no data needs to be sent, at least the transmission block of the wireless LAN module can be set to the power down mode. Also, if an attempt to set up a communications channel is unsuccessful, the device can be set to the power down mode for a predetermined delay period.Type: ApplicationFiled: July 17, 2003Publication date: February 26, 2004Applicant: LG Electronics Inc.Inventor: Hyeong Seog Kim

Publication number: 20030125086Abstract: A transmitting and receiving apparatus can correctly perform transmission and reception of data by quickly determining a signal level of a transmission and reception control signal during a period where a control line of a bus line is not driven. The apparatus includes a master device, slave devices and a bus line connecting the master device and the slave devices. The master device outputs address information identifying the slave device through the bus line. The slave device outputs a reception control signal of the level depending upon capability of data transmission/reception through a control line by driving the control line forming the bus line to the master device. The apparatus also includes level stabilizing signal generating means for outputting a level stabilizing signal to the control line, by driving the control line during a period where the slave device does not drive the control line.Type: ApplicationFiled: December 26, 2002Publication date: July 3, 2003Applicant: NEC CORPORATIONInventor: Kenichi Ito

Patent number: 6556821Abstract: The present invention regards method and apparatus relating to wireless office system. The present invention addresses the problem of enabling it to be determined in the wireless office system (5) when voice mail messages for users of mobile stations having subscriptions in the wireless office system (5) are received at the voice mail system (15), the voice mail system (15) being associated with but not included in the wireless office system (5). The duration(s) of greeting message(s) associated with the voice mail system (15) and the or each mobile station having an associated voice mailbox (16b1-16bM) in the voice mail system (15) is/are measured. The connection times to the voice mail system (15) are measured when calls for the mobile stations are forwarded to the voice mail system (15) from the wireless office system (5). By comparing the duration(s) of the greeting message(s) with the measured connection times, it is determined whether voice mail messages have been received.Type: GrantFiled: July 5, 2000Date of Patent: April 29, 2003Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Magnus Lindgren, John Skördeman

Patent number: 6539238Abstract: A telecommunication user terminal, such as a traditional telephone set or a mobile telephone, provided with a personal address book or internal database (PTD), e.g. located on a user's smart-card. The internal database has several memory locations (IA1, . . . , IA5, . . . ) each storing a call reference that may be selected as calling number by a search key entered by the user on a keyboard (KB) of the telephone. The internal database further has an extra memory location (XE) that stores an extra call reference to a second database (TDS) and that is used in case no matching is found with the other call references. The second database is an external directory service controlled by an operator or service provider. The internal and external database complement one another in a transparent way for the user owing to a fall-through selection circuit (FT) also forming part of the telephone.Type: GrantFiled: May 25, 2000Date of Patent: March 25, 2003Assignee: AlcatelInventors: Dirk Brouns, Michel Diane Cyriel Van Ackere
