A portable electronic device including a first body, a second body, a first hinge connected to the first body, a second hinge connected to the second body, and a linking rod is provided. The linking rod has a first end and a second end opposite to each other, wherein the first end is pivoted to the first hinge eccentric to a rotation axis of the first hinge, and the second end is pivoted to the second hinge eccentric to a rotation axis of the second hinge. The first and the second bodies are rotated to be closed to or far away from each other by the first hinge, the second hinge, and the linking rod.

A gate hinge pin and strap assembly for attachment to a wooden post for supporting a gate including a J-bolt or threaded L-bolt with a metal strap affixed to the bolt between the threads and cylindrical neck portion. A bendable metal strap extends on each side of the J-bolt or threaded L-bolt. The L-shaped rod is threaded into the post until the metal strap contacts the post. Then each bolt of the metal bracket is bent around the post and screws or lag bolts are threaded through the holes and into the post to help secure the hinge to the post and to provide added support for the gate.

Aspects of the disclosure relate to adjusting a shear pin to minimize an impact force felt by an object in a collision with a vehicle. For example, one or more second computing devices may receive, from one or more first computing devices, information indicating that an impact with an object is imminent. In response to the received information, the second computing devices may determine a first shear force for a first shear pin, wherein the first shear force is a desired amount of shear force necessary to break the first shear pin. The second computing devices may send a triggering signal to activate an actuator prior to an impact with the identified impact target. The actuator, in response to receiving the triggering signal, may adjust the first shear pin in a first pinhole, so the first shear pin will break at the first shear force.

The description relates to devices that include hinged portions and controlling rotation of the portions. One example can include a display coupled to a first end of an arm. The example can also include a base rotatably secured to a hollow shaft that is fixed to the arm. The hollow shaft defines an axis of rotation of the arm relative to the base. The base can also include first and second opposing axial cam elements positioned on the hollow shaft and a spring positioned on the hollow shaft. The first and second opposing axial cam elements can be oriented relative to one another such that rotation of the arm toward the base causes the first and second axial cam elements to move away from one another along the hollow shaft thereby compressing the spring.

A multi-position door hinge is coupled to a vehicle and includes a first hinge having a pin support, a pin, and a key. The multi-position door hinge additionally includes a second hinge having a receiving cam, a key way, and a cam groove. The multi-position door hinge is formed by coupling the first hinge to the second hinge by positioning the pin in the receiving cam with the key positioned in the key way.

A hinge assembly for pivotally joining the opposing halves of a carryable case, especially a case for housing an electronic apparatus. The disclosed hinge is adapted to convey electrical conductors from one half of the case to the other, while protecting them from damage by excessive flexing, abrasion, moisture, and debris.

Disclosed are a hinge module, and a case and an electronic device that include the same. The hinge module includes a first case connection connected to a first case, a second case connection connected to a second case, a first hinge shaft having one end connected to the first case connection, a second hinge shaft having one end connected to the second case connection, and a curling part that provides a frictional force to the first hinge shaft, at least a portion of which is inserted into the curling part, to allow the first hinge shaft to rotate with a first torque and provides a frictional force to the second hinge shaft, at least a portion of which is inserted into the curling part, to allow the second hinge shaft to rotate with a second torque different from the first torque.
