Abstract: Magnetic connector systems including a plug connector and a connector receptacle. In one example, the plug connector can include a magnetic target around a signal pin, where the signal pin is insulated from a plug enclosure by an insulating housing. The connector receptacle can include a magnet that is attracted to the magnetic target. The connector receptacle can contact the plug enclosure using one or more conductive springs. The one or more springs can deflect during an insertion of the plug enclosure. In another example, this deflection can act to expel moisture from the connector receptacle through drip holes in an enclosure for the connector receptacle.

Abstract: Connector systems that may be easy to use, may be used to make connections in a limited area, may provide a stable and consistent connection, may provide good impedance matching, and may provide a good user experience. Various embodiments of the present invention may provide connector systems for conveying radio frequency (RF) signals.

Abstract: A test system may test the radio-frequency (RF) performance of wireless electronic devices under test (DUTs). The RF performance of the DUTs may be characterized by a set of performance metrics. The test system may obtain correlation information for each performance metric in the set of performance metrics. The correlation information may identify predictor performance metrics and associated dependent performance metrics in the set of performance metrics. The test system may gather measurement data from a selected DUT by measuring the predictor performance metrics on the selected DUT. The production test station may generate a conditional probability distribution for the dependent performance metric given the measurement data and the correlation information.

Abstract: The present invention provides a method and apparatus for correcting direct current (DC) offsets in radio output signals. The invention comprises a radio processor and a baseband processor. During a calibration routine, the baseband processor measures DC offset produced by the radio processor, generates a corresponding DC offset correction value, and writes the correction value to a discrete memory in the radio processor via a serial processor interface. During a subsequent normal receive operation, the radio processor reads the DC offset correction value from memory and feeds it into a into a digital to analog converter to produce an analog signal that in turn is fed into a radio receive path to nullify undesired DC offset.

Abstract: A system for detection and avoidance of victim services in ultra-wideband (UWB) systems is provided. A detect and avoid module may calculate power averages of Orthogonal Frequency Division Multiplexing tones. The power of tones may be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The UWB subsystem may be configured with known bands of victim services of other radio frequency systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.

Abstract: A system, method, and computer-readable medium for detection and avoidance of victim services in ultra-wideband systems is provided. A detect and avoid module may calculate power averages of OFDM tones. The power of tones may then be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The ultra-wideband subsystem may be configured with known bands of victim services of other RF systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.
