  • Patent number: 9934614
    Abstract: An example wearable display system includes a controller, a left display to display a left-eye augmented reality image with a left-eye display size at left-eye display coordinates, and a right display to display a right-eye augmented reality image with a right-eye display size at right-eye display coordinates, the left-eye and right-eye augmented reality images collectively forming an augmented reality object perceivable at an apparent real world depth by a wearer of the display system. The controller sets the left-eye display coordinates relative to the right-eye display coordinates as a function of the apparent real world depth of the augmented reality object. The function maintains an aspect of the left-eye and right-eye display sizes throughout a non-scaling range of apparent real world depths of the augmented reality object, and the function scales the left-eye and right-eye display sizes with changing apparent real world depth outside the non-scaling range.

  • Patent number: 9930722
    Abstract: Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.
