  • Publication number: 20210057853
    Abstract: An electrical connector includes an inner signal contact, an outer shielding contact, and a cover. The outer contact has a crimping portion including a first crimp wing and a second crimp wing that are bendable towards each other to attach the outer shielding contact to a cable such that ends of the first crimp wing and the second crimp wing extend towards each other when the outer shielding contact is attached to the cable. The cover is configured to cover a braid or a protective layer of the cable that is arranged underneath the ends of the crimp wings when the outer shielding contact is attached to the cable.

  • Publication number: 20210050747
    Abstract: Systems and methods are described for extended foreign object detection (FOD) signal processing. In aspects, an oscillator reset is implemented in a FOD system to mitigate the effects of intermodulation products. In addition, dynamic frequency allocation is implemented to avoid high noise desensitizing the FOD system. Also, a slow sampling mode is implemented to increase a tolerance to transient foreign objects. Reference tracking and auto-recovery is implemented to bridge power outages. Additionally, the FOD system is configured to support position finding for determining an alignment between the vehicle pad and the base pad using a passive beacon transponder circuit and to perform beacon response cancellation as needed in concurrent FOD operation.

  • Patent number: 8983082
    Abstract: Among other things, techniques and systems are disclosed for detecting musical structures, such as downbeats. In one aspect, a method performed by a data processing device includes receiving an input audio signal. The method includes detecting a meter in the received audio signal. Detecting the meter includes generating an envelope of the received audio signal; generating an autocorrelation phase matrix having a two-dimensional array based on the generated envelope to identify a dominant periodicity in the received audio signal; and filtering both dimensions of the generated autocorrelation phase matrix to enhance peaks in the two-dimensional array. The meter represents a time signature of the input audio signal having multiple beats. Additionally, the method includes identifying a downbeat as a first beat in the detected meter.
