20080253552 | Acoustic Echo Canceller - An acoustic echo cancellation device ( | 10-16-2008 |
20100189274 | DEVICE FOR AND A METHOD OF PROCESSING AUDIO SIGNALS - A method is provided which is suitable to cope with non-linear echo paths during acoustic echo cancellation in speakerphones. Non-linear paths occur particularly in hands-free operation of, e.g., a mobile phone, due to driving the amplifier and loudspeaker in the non-linear range. The idea is to combine the commonly known one microphone approach of linear acoustic echo cancellation using an adaptive filter and a post-processor together with a multiple microphone approach using beam forming which separately removes the non-linear part of the echo. | 07-29-2010 |

20080205488 | Differential Phase Coding in Wireless Communication System - In a wireless communications system, such as a multiband Ultra Wideband communications system, data is tranmitted by means of the phases of pulses in multiple frequency bands. Data is encoded in the phase difference between a pulse and a previously transmitted pulse. The previously transmitted pulse may be the immediately preceding pulse in the same frequency band, or may be separated from the present pulse by a number of intervening pulses. | 08-28-2008 |
20080292020 | Reconfigurable Pulse Detector in Wireless Communications System - In a receiver architecture, for example for use in receiving pulses in an Ultra Wideband system, a received signal is applied to a mixer, together with pulses which correspond to expected received pulses. The mixer output is applied to a block, which can be configured either as an integrator or as a filter. When no pulses are being received, this block is configured as a filter, allowing it to lock quickly to any new sequence of pulses, while, when the system has locked to a sequence of pulses, the block is configured as an integrator, so that an improved signal-noise ratio can be achieved. | 11-27-2008 |
20140235164 | CONNECTOR - An apparatus for non-galvanic connection between two electrical circuits is described. A base-unit has an RF power source, a data link and an authentication controller. A contactless unit for communication with a base unit has an RF power receiver, a data link and an authentication controller. The base unit and contactless unit can form a non-galvanic connection to replace conventional connectors, for example in a USB wired bus connection. | 08-21-2014 |

20140096118 | Code Profiling in Embedded ULE Applications - Mobile electronic devices and related methods to achieve an enhanced security level are disclosed. A security module is deeply embedded in a non-open companion chip of the mobile device, wherein the companion chip controls vital functions of the mobile device. Any security technology can be provided by the security module. The security module can, in case of a security violation, disable all vital functions of the companion chip without requiring communicating to other components of the mobile device. The vital functions deployed in the companion chip comprise e.g. system power management or audio functions. | 04-03-2014 |
20140161214 | Automatic Clock Calibration of a Remote Unit Using Phase Drift - An automatic calibration of a clock of a wireless portable part with respect to a clock of a fixed part in a field environment. The calibration performed in the field environment negates the need to calibrate the clock during manufacture and negates the need for an initial field recalibration because of temperature differences between manufacture and the field. In performing the calibration the frequency of the clock of the portable part is varied until the portable part is synchronous with the fixed part to with in a range of timing bits. The portable part is declared calibrated after remaining calibrated for a defined number of data frames. | 06-12-2014 |
