Apparatus for a CMM Arm with Exoskeleton is provided comprising an Internal CMM Arm with a base end and a probe end, and an Exoskeleton driving the Internal CMM Arm through a plurality of transmissions. One or more contact probes, optical probes and tools are mounted on the probe end. The CMM Arm with Exoskeleton is provided in manually operable and automated embodiments. The CMM Arm with Exoskeleton is operable for accurate measurement or for performing accurate operations. Methods are provided for operation of the CMM Arm with Exoskeleton.

This invention contains a suction base meat grinder consisting of a meat grinder with a suction base and manually operated grinding unit. Turning a rotating disk first, the user will firmly fix this meat grinder to the kitchen table surface, as well as lock the base to the upper grinding part. Then the user can rotate the handle to spin the screw bolt and the pedal blade, pushing meat to go through the pedal blade, and be grinded into ground meat, thus finishing the grinding process. Meanwhile, this grinder is made up by the grinding unit and the sucking base. The grinding unit and the sucking base can be separated at cleansing time, making it easier to clean.

A bicycle gear shifting control apparatus has a manually operated shift device, a first gear shifting operation executing component, and a second gear shifting operation executing component. The manually operated shift device operates a front derailleur to shift gears. In response to operation of the manually operated shift device, the first gear shifting operation executing component executes a first gear shifting operation to move the front derailleur from a first shift position of a first sprocket to a second shift position of second sprocket. The second gear shifting operation executing component executes a second gear shifting operation to move the front derailleur a very small amount from the second shift position to a post shift position upon determining that the shifting operation should proceed.

A remotely operated manhole cover for a tanker or trailer is provided. The manhole cover includes a hollow neck which is welded in place in the shell of the tanker or trailer. The neck defines an opening which allows access to the interior of the tanker or trailer for filling or cleaning of the tanker. A lid is pivotable about an axis between a closed position in which the manhole cover is closed, and an open position in which the lid is clear of the neck opening to allow access to the interior of the tanker. The lid is provided with an inflatable seal and locking flanges which extend from a rim of the lid. Pivotal locking members are provided on the neck and are movable between a locked position in which locking member engages the lid locking flange and an unlocked position in which the locking members are disengaged from the lid locking flange. Separate actuators are provide for the cover and the locking members. A controller is provided to energize the cover and locking member actuators and to inflate and deflate the seal. The controller activates the locking member and lid actuators and inflates or deflates the seal in sequence to unlock and open the lid or to close and lock the lid. The controller includes a manually operable switch assembly which activates the manhole cover to open and close the lid. The switch assembly is located remote from the manhole cover, and preferably near the bottom of the tanker.

A power assist module includes a battery powered motor mounted on a manually operated vehicle, such as a bicycle. The power assist module is fixedly mounted on the bicycle and can be easily removed without the need for tools, so that the bicycle can be manually operated in a conventional manner when so desired without carrying the extra weight of the power assist module. The power assist module includes a motor assembly which is operated through a gear reduction assembly to drive a crank drive gear mounted in conjunction with a crank arm of the bicycle.

The present invention relates to an interchangeably manual or automatic ratchet wrench that the user may couple an electric hand grip having a motor therein to the rear end of a stud member of a handle so as to urge a cartridge to rotate in an electric operation manner, or couple a manual hand grip to the rear end of the stud member of the handle so as to urge the cartridge to rotate in a manual operation manner, such that achieving a multi-purpose operation.

A manually-operated canopy deployment system for mounted attachment onboard recreational boats comprises a pair of spring-loaded tubular actuators telescopically assembled and coupled in parallel alignment to deploy a flexible canvas from a roller member transversely mounted between the actuators with a gear box operatively connected to the roller member to control the canvas deployment. Each actuator assembly includes a rearward outer tube, and separate forward and intermediate interior tubes each fitted with inner end caps and coaxially disposed to move longitudinally within the outer tube, with compression springs separately disposed within the respective tube chambers to apply outbound forces axially upon the inner ends of the respective interior tubes. Forward and intermediate cross bars connected across the interior tubes serve to draw the canvas from the roller member and support canvas deployment, with a pair of loop attachments provided on the surface of the canvas to prevent billowing thereof.
