Systems and methods determining measurement confidence for data collected from sensors of a wearable device are herein disclosed. In an implementation, a confidence measurement that a wearable device is worn by a user can be determined by determining that the wearable device is not in motion, comparing sample voltages collected using a light emitter to thresholds indicative of a surface on which the light is being reflected, calculating a signal quality metric using data collected using a pulse oximeter, and comparing the signal quality metric to thresholds indicative of typical biometric data measurements. Other implementations for confidence measurement can include frequency transforming signal data stored in a buffer, performing probabilistic modelling on the frequency transformed data, and determining a confidence measurement using a signal quality estimation based on the modelled data.

A portable mobile device holder that includes a plurality of concentrically-connected frames. The intermediate protective frame, is selectively moveable by a user between a stowed position and a deployed position in which the intermediate protective frame is pivoted outwardly relative to the outer protective frame to orient the mobile device at an approximately 90 degree position relative to the outer protective frame and facilitate hands-free use of the mobile device by a user. The mobile device is mounted on the inner protective frame defining, which is selectively moveable by the user between a stowed position and a deployed position in which the inner protective frame is selectively rotated by the user between approximately 0 to 360 degrees about its longitudinal axis relative to the intermediate protective frame.

The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.

A communication interference rejection system comprising a receiver operatively connected to a device connected to a body of a user. The receiver is configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, the interference component due to human body antenna effect. The receiver is configured to integrate the signal using a relatively low-gain analog integrator and then digitally differentiate the output of said integration.
