An apparatus for generating and manipulating a high-pressure fluid jet includes an assembly coupled to a motion assembly that imparts motion to the assembly along one or more axes. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having an axis of rotation. The two axes of rotation of the two motors can be perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion. The high-pressure fluid assembly incorporates a swivel that can rotate about two axes which may be parallel to the two motors' axes of rotation, allowing the high-pressure tubing contained therein to follow the motion imparted by the gimbal wrist of the motion assembly.

An apparatus for generating and manipulating a high-pressure fluid jet includes an end effector assembly coupled to a manipulator that imparts motion to the end effector. The end effector assembly includes a cutting head coupled to a source of high-pressure fluid and to a source of abrasive. A motion assembly is coupled to the cutting head via a clamp positioned around the cutting head. A nozzle body assembly is removably coupled to the cutting head assembly, which may be separated from the cutting head assembly to allow access to the orifice, without removing the cutting head assembly from the clamp. The clamp has a quick release mechanism and an alignment member. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having a horizontal axis of rotation. The two axes of rotation are perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion.

A catcher tank assembly is provided for a waterjet cutting machine. The catcher tank assembly includes a catcher tank having a plurality of tank sections detachably coupleable together in a side-by-side manner to collectively define a catcher tank having a desired configuration. The catcher tank assembly further includes a workpiece support system detachably coupleable to an interior cavity of the catcher tank. The workpiece support system may include a plurality of workpiece support modules arrangeable in an array to support a workpiece platform of the waterjet cutting machine. The workpiece platform may be formed, for example, by a series of slats supported transversely to parallel rows of the workpiece support modules. Methods and systems which relate to or include the aforementioned catcher tank assembly are also provided.

A system used for the prevention of positional plagiocephaly in which an infant receiving member includes an infant supporting surface, a first portion, and a second portion. An inclined member is positioned at least partially under the first portion of the infant receiving surface such that the first portion of the infant receiving surface is inclined.

A contour follower includes a plurality of sensors spaced around a waterjet nozzle, each of the sensors being configured to measure a distance between a working surface and a first plane, perpendicular to a longitudinal axis of the nozzle. The sensors may include hall-effect sensors lying in the first plane and magnets lying in a second plane, parallel to the working surface. A detecting circuit processes signals from the sensors to determine an angle of the working surface, relative to the first plane, and a distance between an aperture of the nozzle and the working surface. A collision detection sensor provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. A shield plate blocks and dampens secondary spray-back of cutting fluid occurring at low angles above the working surface.

An infant bed of the present invention includes a frame, a mattress having a first portion and a second portion, and a mattress support that is supported on the frame for supporting the mattress. The mattress support has a first portion that supports the first portion of the mattress. The mattress support also has a second portion that is mechanically tilted about a central longitudinal axis so as to laterally tilt the second portion of the mattress to either side relative to the first portion of the mattress. The infant bed of the present invention is particularly useful for preventing positional plagiocephaly.
