A nanoscale positioning system for positioning a positionable component includes a motion platform including a first end, a second end, a shuttle positioned between the first end and the second end and configured to support the positionable component, a flexure member, and a fluid passage extending through the flexure member from the first end to the second end of the motion platform, and a pressure controller coupled to the motion platform and fluidically connected to the fluid passage, wherein the pressure controller is configured to selectably provide a fluid pressure in the fluid passage to flex the flexure member whereby the shuttle is displaced along a motion axis of the motion platform.

An image-capturing device includes a camera and a rotating mechanism for orienting the camera in multiple directions. The rotating mechanism includes a motor; a driving gear; a first transmission module including a first input gear, which is selectively engaged with and transmitted to rotate by the driving gear at a first position, and transmitting the camera to rotate in a first direction with rotation of the first input gear; a second transmission module including a second input gear, which is selectively engaged with and transmitted to rotate by the driving gear at a second position, and transmitting the camera to rotate in a second direction with rotation of the second input gear; and a clutch mechanism including a clutch device for driving the driving gear to switch between the first position and the second position. The clutch device includes a solenoid.

A platform to be used to secure objects for delivery by air. As a platform is lowered toward the ground, the legs of the platform touch the ground and interact with each other to stabilize the platform. A stable platform does not tip over. The platform may stabilize itself even when lowered onto uneven terrain. As the platform is lowered, the legs, except the last leg, move upward or inside the body of the platform until the last leg touches the terrain. On uneven terrain, the legs of the platform move upward or inside different amounts, so the legs have different lengths. The last leg to touch locks the other legs so that they cannot move up or down thereby stabilizing the platform. An incompressible material is used to detect when the last leg touches the terrain and to lock the other legs.

Provided is a configurable device including a screen and configured to support a computer, the configurable device further including a support frame having consecutive operating portions and joints defining axes of rotation between the operating portions, reciprocal positioning means of the operating portions, the operating portions further including a base unit, an upper unit connected to the screen, and at least one intermediate unit connected between the base unit and the upper unit, the configurable device lastly including actuation members configured to automatically control the positioning means.

The description relates to devices that include hinged portions and controlling rotation of the portions. One example can include a display that is configured to rotate relative to an axis. The example can also include a clutch assembly interposed between first and second planet gear assemblies positioned along the axis. The first and second planet gears configured to multiply resistance to rotation around the axis that is supplied by the clutch assembly.

An electronic device can include a motor that rotates a shaft that is coupled to a gear. A belt or a chain can be placed in contract with the gear and other rotational devices. For optimum performance, the chain or chain should be adjusted to an optimum tension. The tension can be adjusted by moving the motor and securing the motor in a position the provided the optimum tension. Alternatively, the motor can be in a fixed rigid position and an idler pulley in contact with the belt or chain can be positioned to provide the optimum tension.
