An end effector for a robotic arm is disclosed. The end effector includes a grasping apparatus having a gripping member and an appendage extending from the gripping member forming a channel between the griping member and the appendage. The channel is configured to receive at least a portion of an article, such as a latch for a container, to be manipulated by the end effector.

A rotary actuation mechanism comprising an actuator having a body, and a slider movable on a linear path relative to the body. A first linkage can be pivotally coupled to the body at a first pivot having a first axis. A second linkage can be pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot. A length of the first linkage between the first pivot and the third pivot can be equal to a length of the second linkage between the second pivot and the third pivot. The slider can be movable to position the second axis in a collinear relationship with the first axis. The rotary actuation mechanism can include an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.

Rotary actuation mechanism

The present invention describes, generally, a method and system for controlling the dynamics of an actuatable load functioning or operable within a servo or servo-type system, wherein the dynamics of the load are controlled by way of a unique asymmetric pressure control valve configured to provide intrinsic pressure regulation. The asymmetric pressure control valve, which may be referred to as a dynamic pressure regulator because of its capabilities, utilizes different sized free floating spools that are physically independent of one another and freely supported in interior cavities of respective corresponding different sized valving components that make up the valve body to regulate the pressures acting within the overall system between the control or pilot pressure and the load or load pressure. The dual spools of the pressure control valve, although physically independent of one another, function in cooperation with one another in an attempt to maintain a state of equilibrium in the system, namely to keep pressure acting on or within the actuator (the load pressure), or the feedback pressure corresponding to the load pressure, the same as the control or pilot pressure. Moreover, pressure regulation and control is intrinsic to the asymmetric pressure control valve because of the configuration and function of the dual spools and the feedback system acting on the spools, thus eliminating the need for electronically or mechanically user controlled systems.

The present invention features a sleeve valve comprising an elongate body having an outer surface and including a lumen for receiving a fluid and an associated fluid pressure therein and for defining a flow path of the fluid; at least one fluid flow port formed through the outer surface that is in fluid connection with the lumen; and a sleeve slidably disposed about the outer surface of the body and configured to displace across the fluid flow port to precisely regulate fluid emission through the fluid flow port. The sleeve and elongate body are operably related in a manner so as to provide some degree of fluid force compensation, such that the forces necessary to displace the sleeve across the fluid flow port are substantially unaffected by the fluid pressures acting within the body and at the fluid flow port. In other words, the fluid pressures do not substantially contribute to the resistance in the sleeve during actuation.

An apparatus and method for extracting energy from an internal combustion engine. The internal combustion engine includes a chamber having a primary piston and a secondary piston with a combustion portion of the chamber situated adjacently between the primary piston and secondary piston. The secondary piston includes a substantially lesser mass than that of the primary piston. The chamber includes at least one fluid port for supplying fuel to the combustion portion and an out-take port for releasing combustive exhaust. The chamber includes a controller for controlling the combustion therein at selected cycles of the primary piston. With this arrangement, the secondary piston is configured to draw a portion of energy from combustion controlled by the controller in the chamber. Such portion of energy is provided with a rapid response to an energy transferring portion interconnected to the secondary piston, which in turn, transfers and/or converts the energy for acting on a load or external application.

Rapid response power conversion device

An improved piston-type vacuum pump comprises a reciprocating piston disposed within a cylinder having a proximal end and a distal end, an inlet port formed in the side of the cylinder near the proximal end, and a spring-biased outlet valve, such as a poppet valve or a rocker valve, disposed at the distal end of the cylinder. The piston stroke is configured to provide zero or negative clearance between the piston head and the face of the outlet valve at the end of the compression stroke. The piston reciprocates within the cylinder from a first position wherein the surface of the piston head is proximal of the inlet port, to a second position wherein the surface of the piston head is beyond the distal end of the cylinder, so as to contact the face of the outlet valve in its open position. The piston top and outlet valve face remain in contact until the piston has retracted into the distal end of the cylinder, allowing the valve to seal the distal end of the cylinder prior to the beginning of the expansion stroke, such that there is substantially no dead volume within the cylinder at the beginning of the expansion stroke.
