A sports towel includes an integrated, semi-rigid squeegee tab along one edge of the towel. The squeegee tab is tapered along its outer edge, allowing for effective wiping of planar surfaces such as the visor on a sporting helmet. The towel is securely attached to the squeegee tab through a double stitch that extends through a folded-over edge of the towel and a towel-receiving slot on the top of the squeegee tab. An indicia-receiving slot on the top side of the squeegee tab provides an opportunity for product branding or logo placement. Additionally, the towel includes hook-and-loop material to allow for easy attachment to a player's uniform. The invention offers a convenient and efficient solution for athletes to keep their helmet visors clean and dry during gameplay.

A shear pin supported cleaner finger assembly includes a frame member, a support member attached to the frame member, the support member defining a pivot point and a reactive point. A cleaner finger is pivotally attached to the support member at the pivot point, and a shear pin is positioned at the reactive point.

A station uses cleaning mechanisms to clean sensors of mobile robots. The mobile robots may use data from the sensors to navigate around an environment such as an inventory warehouse. A sensor of a mobile robot can become dirty over time as dust or other debris accumulates on the sensor. Since the mobile robots can navigate to a station for automatic sensor cleaning, a human does not need to manually clean the sensors. Multiple mobile robots may share one or more stations in the environment and coordinate a schedule to have their sensors cleaned. The stations may also charge a battery of a mobile robot simultaneously while cleaning the mobile robot's sensors.

Generally, a panel maintenance system including a panel maintenance assembly configured to move over a plurality of panel modules. Specifically, a panel module including a first frame including a first plurality of frame members joined to enclose a first panel. The first plurality of frame members including a first frame inner side configured to capture the first panel within the first frame and a first frame outer side configured to provide a first track axially extending between first and second ends of at least one of the first plurality of frame members. The first track configured to engage a drive element of a panel maintenance assembly which operates to move the panel maintenance assembly over the first panel. The panel maintenance assembly bears one or more components which function to maintain the first panel.

A device for partially removing the coating of a metal plate includes a die and a punch which together form a gap through which the metal plate is fed. The device also includes a drive for generating a movement of the die and the punch relative to the metal plate. The die has a protruding blade on the its surface facing the metal plate. A cutting edge of the blade extends in a direction opposite to the movement direction of the metal plate. The device further includes a pressing device for pressing together the die and the punch. The punch includes a roller which rolls on the metal plate surface opposite the blade.

Embodiments of the present disclosure address problems presented by contaminants, such as dirt and debris, by providing an optical apparatus with techniques and methodologies for self-cleaning. In that regard, embodiments of the present disclosure employ techniques and methodologies for maintaining a very thin (e.g., few microns thick) layer of liquid, such as a non-stick liquid, on an optical window of an optical body that shields or protects an optical device.

An autonomous mower including a housing; a mowing module, a traveling module, an information collection device, an energy module, a control module and the control module includes an identification unit, and an alarm module. The autonomous mower has a security patrol working mode in which the identification unit analyzes and judges whether an abnormal object exists in the working area according to the information collected by the information collection device; if the abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside. Therefore, the autonomous mower can achieve a security patrol function in addition to having a function of trimming the lawn. The autonomous mower has multiple uses, so as to save the cost.

A hand tool includes a handle which is a hollow handle with a space defined therein. A connection portion has a slit defined in the first end thereof. The connection portion has two ribs extending inward from an inside of the second end thereof. The handle has a tubular portion extending from one end thereof. A protrusion extends outward from outside of the tubular portion. The tubular portion is inserted into the second end of the connection portion, and the ribs are engaged with the protrusion. A blade has a body and a toothed portion. The toothed portion is inserted into the slit of the connection portion. A cooling material is located in the space of the handle. The connection portion of the handle is connected to the toothed portion of the blade. The cooling material performs as a weight in the handle.

A scraper for use with aquariums incorporates a body having a slot adapted to removably receive a scraping element and a handle extending form the body. The handle has at least two removable and adjustable links.

A multipurpose kitchen utensil useful for wiping the wire elements of a whisk has a working portion containing a plurality of slots arranged arcuately and extending radially in spaced relation to one another and structured to receive the wire elements of a whisk. The utensil includes a central core member formed of a material capable of maintaining its shape when subject to external pressure, and an overlying layer of a more resilient material such as silicone. The radial slots extend inwardly and taper to an edge capable as serving as a spatula.
