Robotic and / or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both. A set-up mode employs an intuitive user interface in which one or more joints are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. The system may provide a detent-like manual articulation that is not limited to mechanically pre-defined detent joint configurations. Embodiments of the invention provide, and can be particularly well-suited for manual movement of a platform supporting a plurality of surgical manipulators in a robotic surgical system or the like without having to add additional input devices.

The disclosure relates to optical heterodyne detection cavity ringdown spectroscopy. In one aspect the disclosure relates to an optical system comprising a ringdown cavity cell defining a resonant optical cavity, means for directing coherent light selected from the group consisting of continuous or quasi-continuous light into said optical cavity, means for altering the resonant optical cavity so as to generate a frequency shift of the coherent light in the optical cavity, means for coupling said coherent light into the optical cavity and means for decoupling the frequency shifted coherent light out of said optical cavity, means for optically combining said decoupled frequency shifted coherent light with another portion of coherent light not in optical communication with the optical cavity and means for optical heterodyne detection of the intensity of said combined light. A method for optical detection is also described as well as methods and apparatus for detecting a parameter of a sample.

An improved vehicle brake system for controlling the frictional braking force and the regenerative braking force to be applied to a wheel of a vehicle. The brake system reduces the regenerative braking force to a predetermined force and keeps the regenerative braking force at the predetermined force before the start of anti-lock control. When the anti-lock control starts, the brake system decreases the regenerative braking force from the predetermined force. With this arrangement, it is possible to quickly eliminate a locking tendency of any wheel of the vehicle, thereby stabilizing the vehicle.

Floorboards provided with a mechanical locking system including a locking strip protruding from a first edge of a first floorboard. The locking strip is provided with a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction. The first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge. The second edge is provided with a calibrating groove adjacent the locking groove. Also, a method for producing a mechanical locking system.

A dampened slide for a wedge assembly includes a slide housing having perimeter walls. First and second alignment members connect to the perimeter walls, each having a deflectable portion. The deflectable portions extend opposite to each other and transverse to a centerline of the housing.
