Aspects of the disclosure relate to techniques for launching high-altitude balloons. In one aspect, a balloon launching system is provided. The balloon has a balloon envelope, a payload attached to the balloon envelope and a launching projection. The launching system includes a releasable restraint attached to the balloon between an apex and bottom of the balloon envelope. The releasable restraint is arranged to temporarily hold the balloon envelope. The launching system also includes a payload positioning assembly. The payload positioning assembly is configured to position the payload during launch of the balloon and includes a member configured to attach to the launching projection. When attached, the member is also configured to maintain the position of the payload relative to the balloon while the releasable restraint is temporarily holding the balloon envelope.

Balloon launching apparatuses

An eyepiece includes a first lens body having a first interface side and a second lens body having a second interface side. At least one of the first and second interface sides includes a recess. The first and second lens bodies are mated together along the first and second interface sides to form a cavity at the recess. A lightguide insert is provided that has a shape and a size to fit within the cavity. The lightguide insert includes an in-coupling region to receive display light into the lightguide insert and an out-coupling region to direct the display light out of the lightguide insert through the first lens body.

Lens with lightguide insert for head wearable display

The present disclosure provides methods and systems for bonding multiple wafers. An example system may include a sealable chamber with a first and second substantially vertical post positioned inside of the sealable chamber. The system may also include a first latch connected to the first post via a first pin, wherein the first pin allows the first latch to rotate about the first pin. The system may also include a second latch similarly configured to the first latch. The system may also include a base plate positioned between the first and second posts. The base plate is arranged such that when a first wafer rests on the base plate and a second wafer rests on the first and second latches, moving the base plate from a first position to a second position causes a top surface of the first wafer to contact a bottom surface of the second wafer.

Methods and systems for bonding multiple wafers

An eyepiece for a head wearable display includes a first lens body having a first interface side in which a first recess is disposed and a second lens body having a second interface side in which a second recess is disposed. The first and second lens bodies are mated together along the first and second interface sides and the first and second recesses are aligned to form a cavity. A lightguide insert is provided that has a shape and a size to fit within the cavity defined by the first and second recesses. The lightguide insert includes an in-coupling region to receive display light into the lightguide insert and an out-coupling region to direct the display light out of the lightguide insert through the first lens body.
