Abstract: The description relates to input devices that can be secured to and used to control various devices. One example input device can include a housing defining a top surface that includes controls. The housing can define a recess that includes generally opposing upper and lower surfaces that extends at least partially under and parallel to the top surface. A self-adjusting gripping mechanism can extend into the recess through the lower surface and can be biased toward the upper surface. The self-adjusting gripping mechanism can be configured to be contacted by devices having a range of thicknesses and configured to grip individual devices within the range of thicknesses between the self-adjusting gripping mechanism and the upper surface.

Abstract: A multi-pivot timing chain comprises first timing links in a first timing chain layer coupled together via meshing gear teeth, and second timing links in a second timing chain layer coupled together via meshing gear teeth. Pins rotatably couple the first timing links to the second timing links. Each of the timing links comprises opposing first and second gear portions comprising gear teeth, and first and second flexures connecting the two gear portions. The flexures are in tension and configured to cause a pair of meshing gear teeth in an adjacent timing chain layer to be in compression, thereby creating resistance to rotation of the timing links that comprise the meshing gear teeth.

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 example can also include a first exoskeletal hinge segment secured to the first portion and a second exoskeletal hinge segment secured to the second portion. The first exoskeletal hinge segment can define an arcuate tab that travels in an arcuate cavity defined by the second exoskeletal hinge segment to allow relative rotation between the first and second portions.
