Abstract: A device for applying an axial force includes a longitudinal axis with a first compression surface located at a first end of the longitudinal axis and a second compression surface located at a second end of the longitudinal axis. A plurality of resilient members is positioned between the first compression surface and the second compression surface. A first resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. A second resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. The device has a compressed state and an expanded state where the first compression surface and second compression surface move in a direction of the longitudinal axis between the compressed state and the expanded state.

Abstract: An optical system comprises a first optical module and a second optical module. A tensioned element includes an upper segment attached to the first optical module and a lower segment attached to the second optical module. Movement of the tensioned element thus generates opposing movement of the first and second optical modules, the first optical module moving in a direction parallel to a direction of movement of the upper segment, and the second optical module moving in a direction parallel to a direction of movement of the lower segment.

Abstract: The description relates to devices, such as computing devices that have hinged portions. One example can include a first portion and a second portion. The first portion can define a first hinge axis and can be resiliently biased toward the first hinge axis. The second portion can define a second hinge axis and can be resiliently biased toward the second hinge axis. A first cam can operate relative to the first hinge axis and is slidably secured to the first portion. A second cam can operate relative to the second hinge axis and can be slidably secured to the first portion. When the first and second portions are oriented at an acute angle the second cam can force the second portion away from the second hinge axis while the first cam can allow the first portion to remain biased toward the first hinge axis.

The headband may include a first loop positioned around the head, and possibly a second loop affixed to the first loop and positioned over the head.
