Abstract: A lens module in a head-mounted device may include a fluid-filled chamber, a semi-rigid lens element that at least partially defines the fluid-filled chamber, and at least one actuator configured to selectively bend the semi-rigid lens element. The semi-rigid lens element may become rigid along a first axis when the lens element is curved along a second axis perpendicular to the first axis. Six actuators that are evenly distributed around the periphery of the semi-rigid lens element may be used to control the curvature of the semi-rigid lens element. The semi-rigid lens element may initially be planar or non-planar. For example, the semi-rigid lens element may initially have a spherically convex surface and a spherically concave surface. A tunable spherical lens may be incorporated into the lens module to offset a parasitic spherical lens power from the semi-rigid lens element.

Abstract: Embodiments of the disclosure generally relate to bearer establishment in a wireless communication network. In response to that a data packet is to be transmitted from a first terminal device served by a first base station to a second terminal device in a shortcut way, the first base station determines a second base station serving the second terminal device and a target bearer for carrying the data packet from the second base station to the second terminal device. Then, the first base station causes the data packet to be transmitted from the second base station to the second terminal device on the target bearer. In this way, latencies of bearers related to core network transportation can be reduced.
