Abstract: A method for handling a radio-frequency connection between a control unit and a mobile device of an access control system. The mobile device is connected to the control unit using radio-frequency signal communication. The method comprises obtaining an indication of a first event generated in the access control system in response to a first request for the control unit to arrange to carry out an action. After a release of the connection by the control unit, the method further comprises obtaining an indication of whether or not a second event has been generated in the access control system in response to a second request for the control unit to arrange to carry out the action. The method further comprises determining, based on the indication of whether or not the second event has been generated, whether or not to allow the mobile device to re-connect to the control unit.

Abstract: A method in an access control system comprising a control unit connected to one or more mobile devices using radio-frequency signal communication. The control unit sends a motion status request to a connected mobile device out of the one or more connected mobile devices in response to the generated event. The method comprises determining an indication of a probability that the connected mobile device is associated with the event. Determining the indication is based on received signal strength data, measured by the connected mobile device on the radio-frequency signals transmitted by the control unit during a first predetermined period of time before the motion status request is received, and motion sensor data collected from a motion sensor comprised in the connected mobile device during a second predetermined period of time before the motion status request is received.

Abstract: A method and apparatus for providing privacy for telephone conversations over communication networks is disclosed. For example, a telephony endpoint device comprises a microphone for receiving an audio signal and a gain boost circuit, coupled to the microphone, for applying a gain boost to the audio signal. The telephony endpoint device also comprises a switch, coupled to the gain boost circuit, wherein operating the switch will control whether the gain boost is to be applied to the audio signal.

Abstract: This is a method for use in a teleconference that troubleshoots echo problems. After receiving a code to begin the troubleshooting process, all legs of the teleconference are muted except a test leg. That test leg is evaluated for echo. The process is repeated for each of the legs of the teleconference. After automatically measuring echo on all legs, results are reported to a moderator or host, who can take action such as muting all legs with echo, or discussing remedial action with each participant on a leg with echo.
