The Surface Type Cover is a slim keyboard that has moving keys. Use it to get the speed and feel of a classic keyboard and to go from tablet to laptop. Type Covers click magnetically into place and provide protection for your Surface touchscreen.

Helical antenna

A helical antenna has a helix supported by a helix support. The helix support includes at least one piece of flexible sheet having its two surfaces covered with a layer antistatic material. The flexible sheet is curlable into a revolution surface configuration to form a revolution surface-shaped support section for at least partially supporting a portion of the helix component there around. A grounding mechanism electrically grounds the external sheet surface to the helix and the two sheet surfaces to one another when in the revolution surface configuration while a locking mechanism locks the flexible sheet in the revolution surface configuration. The combination of the helix and the flexible support renders the antenna structurally relatively rigid in all directions.

Surface coverings containing aluminum oxide

A surface covering comprising at least one layer containing aluminum oxide is disclosed. Preferably, the aluminum oxide is present in the outermost layer of the surface covering which is exposed to the environment. A method to improve wear and / or stain resistance to a surface covering is also disclosed and includes adding an effective amount of aluminum oxide to a top coat layer or outermost layer of a surface covering. Methods of making the surface covering are also disclosed.

Stepped polycrystalline diamond compact insert

The present invention addresses this need in the art by providing a cutter insert comprising a plug section and a cutter pedestal. The cutter insert is preferably formed of tungsten carbide, except for two exterior surfaces covered with PDC. The plug section may be circular or oval in cross section perpendicular to the axis of the insert. The plug section and the pedestal each defines a shoulder which is coated with a PDC layer. In this way, two cutting surfaces are applied to the formation, enhancing the cutting ability of the insert.

Irregular, rotational tessellation surface covering units and surface covering

A surface covering unit comprises x primary elements, wherein x is an integer equal to or greater than 1. Each primary element is a rotational tessellation having a plural pairs of sides extending in a generally radial direction from plural vertices, respectively. In each pair, the two sides are rotationally spaced by an angle of 60, 90, 120 or 180 degrees, and each side is substantially a rotational image of the other side. The sum of the plural vertices angles is 180, 240, 270, 300 or 360 degrees. Preferably, all of the sides are irregularly shaped, but one or more sides could be wholly or partially straight. Optionally, one or more edges of each unit are marked with indicia to facilitate matching mating sides of adjacent units. A wide variety of units may be constructed having different numbers and arrangements of primary elements. As all the units are combinations of primary elements, they readily mate with each other. A surface covering comprises a multiplicity of surface covering units assembled to form a continuous surface without overlap between units and without substantial gaps between units. Because of the irregular side configurations, and different sizes and shapes of individual units, one can construct a continuous surface that has a natural, random and apparent custom appearance. Optionally, minor surface and edges variations are made from unit to unit to further enhance the natural appearance of the surface covering.

InactiveUS20090223162A1Quick installationEasy and fast and flexibilityCovering/liningsFlooringEngineeringWood plank
A plank is provided that has opposing first and second ends extending along a width of the plank, opposing first and second longitudinal sides extending along a length of the plank, and opposing top and bottom surfaces. The plank can have a tongue edge at the first end and a groove edge at the second end. The tongue edge can be detachably lockable into the groove edge of an adjacent, identical plank. Surface covering systems having a plurality of the planks connected together are also provided.
