Robotic posture transfer assist devices for assisting a posture transfer of a patient in a bed may include a device body, a stabilizer coupled with the device body and the bed, and at least one robotic arm having a plurality of degrees of freedom, wherein the robotic arm may be coupled with the device body. Robotic posture transfer assist devices may further include an end-effector removably coupled with the robotic arm, a controller module that provides a control signal to the robotic arm to control a movement of the robotic arm about the plurality of degrees of freedom, and a user input device that provides a command signal to the controller module to command the movement of the robotic arm, wherein the control signal provided by the controller module corresponds with the command signal..

Manipulator for surgical tools
The invention is a novel compact robotic manipulator with a special configuration that supports a remote center-of-motion attribute, so it has the ability to accurately and conveniently manipulate and re-orient in 2 degrees of freedom, and to firmly “lock” in place, special purpose surgical tools necessary for minimally invasive therapy. The new features include a sophisticated joint-link structure and configuration that comprises two arcuate links that enable comfortable maneuverability of the end effector or the tool about a pivot point, typically the port of entry of the tool to the patient's body, while preventing the enlargement of the key hole, in the constrained and limited workspace of surgical environments.

Solar collector stabilized by cables and a compression element
A solar collector system including solar elements connected to form an array for intercepting the sun's radiation, a compression element that is positioned substantially perpendicular to the array, and pairs of cables that run from opposite sides of the array to the compression element to mutually stabilize each portion of the array to which the pair of cables connects. A support structure is provided for securing the array to a fixed structure.
