Abstract: Various aspects of techniques, systems, and use cases include provide instructions for calibrating or object identification in a human-robot interactive environment. A technique may include displaying a back illumination image having at least two distinct sections, capturing a scene including the first back illumination image and an object obstructing a portion of one of the at least two distinct sections of the first back illumination image, and identifying, using an orientation of the display screen relative to the camera (e.g., obtained via calibration), location information of the object relative to a robotic device based on the first scene. The technique may include outputting the location information.

Abstract: An integral engine component is disclosed. The integral engine component may have a solid first member and a second member cast in place relative to the solid first member. A metallurgical bond may exist between the solid first member and the second member, and the melting temperature of the solid first member may be lower than the melting temperature of the second member.

Abstract: The present invention mainly relates to a manufacturing process for a master cylinder, in particular a tandem master cylinder, such process including a dead-stroke adjusting step, and it also concerns a master cylinder manufactured using said process.

Abstract: A shovel having an adjustable blade angle for changing the angle of the blade with respect to the handle. The shovel having an adjustable blade angle includes a handle member. The handle member is elongate and has a first end and a second end. A blade member has a front surface and a back surface. The blade has a back edge. A rod is securely attached to and extends away from the back edge of the blade member. A pair of protruding members is integrally coupled to and extends away from the second end of the handle member. The protruding members are spaced such that each of the protruding members may be positioned on an opposite side of the rod. The protruding members are pivotally coupled to the rod such that the blade member is pivotable with respect to the handle member. The handle member is selectively lockable with respect to the blade member.
