Abstract: A method for key generation at a terminal device supporting at least two communication modes of operation is described. The method comprises, at a terminal device comprising a key derivation function: receiving at least one input parameter from a first wireless communication system; generating a first key in the key derivation function using the received at least one input parameter and at least one first locally stored input parameter in order to transmit in a first mode of operation on the first wireless communication system; and generating a second key in the key derivation function solely using at least one second locally stored input parameter in order to transmit in a second mode of operation on a second wireless communication system; wherein the at least one second locally stored input parameter is arranged to enable the second key to be used as the first key.

Abstract: A user-configurable modular audio control surface comprises master modules for controlling global surface properties and channel modules for controlling one or more individual audio channels. The modules are disposed in a two-dimensional spatial arrangement such that any module can occupy a location within the control surface not occupied by another module. The modules are connected to each other and to external platforms hosting media applications and plug-ins via a network. Control surface users can interact with external applications via remote graphical user interfaces displayed on modules within the surface, and can automate multiple external applications using an automation system built into the surface. Automation line graphs and metadata for both internal and external applications are displayed over the corresponding waveform displays that can include audio ahead of a current playback location.

Abstract: A cellular communication system comprises a Multiple-In Multiple-Out (MIMO) transmitter and receiver. The MIMO transmitter comprises a message generator for generating MIMO messages comprising selected training sequences and transceivers transmitting the messages on a plurality of antennas. The training sequences are selected by a midamble selector from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver comprises a transmit antenna detector which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.

Abstract: A method is disclosed for controlling operational parameters of a wireless reader device and/or one or more other devices based on proximity of the wireless reader device to a wireless electronic circuit. At a first location, the wireless reader device and/or the one or more other devices are controlled based on a first operational parameter. At a second location, interrogation signals are transmitted from the wireless reader device, and response signals are received at the wireless reader device. The response signals are transmitted from the wireless electronic circuit in response to receiving the interrogation signals from the wireless reader device. The response signals convey a control parameter to the wireless reader device that is associated with a second operational parameter. Thereafter, the wireless reader device and/or the one or more other devices are controlled based on the second operational parameter.

Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.

Abstract: A method and system for managing user authentication. First authentication data associated with a user is received from a first authentication mechanism. The first authentication data is generated in response to the first authentication mechanism successfully authenticating the user. In response to receipt of the first authentication data, a first identifier associated with the user is registered. The first authentication data is associated with the first identifier. In response to associating the first authentication data with the first identifier, second authentication data associated with the user is received from a second authentication mechanism. The second authentication data is generated in response to the second authentication mechanism successfully authenticating the user. The second authentication data is associated with the first authentication data and the first identifier.
