An apparatus for supporting a substrate is described that has a ball adapted to minimize damage between the substrate support and the substrate supported thereon. In one embodiment, an apparatus for supporting a substrate includes ball disposed on an inclined ball support surface. The ball support surface is adapted to bias the ball toward one side of the ball support surface thereby providing space for the ball to roll as the substrate supported thereon changes in length when exposed to thermal influences. In another embodiment, the apparatus further comprises a cage adapted to capture the ball to the ball support surface.

A combination writing pen and stylus is disclosed. The device has an internal ink cartridge deployable through a hole in the stylus tip. The stylus tip extends from a sleeve that is formed of a conductive elastomeric material. The sleeve extends up a rigid shaft of the device such that it contacts a sufficient ground. The stylus tip may be coated with a protective material that adjusts the coefficient of friction and prevents carbon deposits on the touch screen. A sufficient contact patch is achieved to simulate a human finger so as to overcome false positives from common touch screen logic. This is done by altering tip geometries around an air cavity within the sleeve.

A cosmetic applicator formed from ceramic material covered in a metal sheath. The tip is designed to provide a product chilling effect when applying creams, lotions, treatment products, etc. The applicator is provided with a relatively substantial mass of ceramic material so that it has a greater thermal capacity than the dose of cosmetic and the application area combined. The applicator is in the form of a molded-ceramic applicator head or applicator tip sheathed, coated or plated in metal. The tip provides a relatively larger product-chilling effect to both the dose of cosmetic applied and to the user's skin in the application area when applying creams, lotions, treatment products, etc. The applicator provides an application device which will deliver the creams, lotions, treatment products, etc. such that the temperature of the product being delivered is lower than the temperature of the skin, and to provide a means of lowering the temperature of the skin by virtue of the thermal absorption capacity of the applicator head or tip, and to provide a vehicle by which formulations may be activated or enhanced by specific compounds in the ceramic material from which the applicator tip is comprised.
