A linearly polarized transparent or translucent material is stretched to follow a sinusoidal shape so all parts of the resulting panes or lenses are themselves sinusoidal. By providing a structure of two panes or lenses of such material, moving one relative to the other in a linear direction varies an amount of light passing through. Thus, such a linear movement adjusts light translucence, luminosity intensity, brightness and dimness. Applications include windows (home, office, car), motor vehicle windshields, sunglasses, optical lenses, computer monitors, televisions, and fluorescent light fixtures.

A method for identifying shipment shortages on pallets is provided. In some embodiments, the method includes taking one or more digital images of a pallet with a shipment thereon to estimate the shipment's volume. The method further includes estimating an anticipated shipment volume based on the shipment's invoice information, and comparing the estimated shipment volume to the anticipated shipment volume to calculate volume mismatches. The volume mismatches can be used as an indicator of any shipment errors.

An agricultural yield apparatus with a container made of a material that is impermeable to water and inert without leaching impurities to the surrounding natural environment and thereby is effective in segregating contents of the container from the surrounding natural environment and blocking seepage of the contents to the surrounding natural environment. The container encloses nutrients, water and a growth medium such as soil. The top of the container is closed except for at least one water and nutrition port and at least one vegetation growth port (or neck). The trunk of the vegetation passes through the at least one vegetation growth port (or neck). The container may be closed by a root membrane overlay having holes. The trunk of the vegetation passes through the holes in the holed root membrane overlay. Root direction channels may be beneath the overlay.

A dual chuck device with a shaft grasping assembly and a screw stem grasping assembly each with respective jaws, driving mechanism and sleeve. Upon turning a respective sleeve in one direction or the reverse direction, the respective drive mechanism moves the jaws toward or away from a grasping position. In the grasping position, the screw stem is grasped. When the sleeve is presses against a working surface being penetrated by a driven screw, the driving mechanism moves the jaws in the reverse direction to move them apart to no longer grasp the screw.

An electric motorized toothbrush with a pair of bristle units spaced apart from each other by a gap and a third bristle unit bordering the gap by being closer to each of the bristle units of the pair than the bristle units of the pair are to each other. A motorized gear transmission, via associated spindles, rotates the pair of bristle units in opposite directions and either rotates or reciprocates the third bristle unit. The bristle units of the pair include a respective cylinder and bristles that extend radially outward from the respective cylinder and the bristles may be of varying lengths. The bristles rotate in a direction away from the gum line while the teeth are inserted into the gap.

An agricultural yield pod or agricultural yield pad with holed root membrane overlay. The agricultural yield pod encloses soil and vegetation in the soil. The top of the agricultural yield pod is closed except for at least one water and nutrition port and at least one vegetation growth port (or neck). The trunk of the vegetation passes through the at least one vegetation growth port (or neck). The agricultural yield pad is closed by the holed root membrane overlay and contains soil and vegetation in the soil. The trunk of the vegetation passes through the holes in the holed root membrane overlay. Root direction channels may be beneath the overlay.
