Abstract: A method and apparatus for disassembling a set top box is disclosed. The method includes providing the set top box including: a top cover, a base, and cover retention clips, wherein the cover retention clips are V or U shaped for securing the top cover to the base, providing a release fixture including a retention clip release finger, inserting the release fixture into the set top box, disengaging the cover retention clips using the retention clip release finger, and removing the top cover from the base.

Abstract: An oxidative thermochemical drying treatment of naturally occurring organic substances, to prepare a new class of hydrophobic oleophilic products, and a new class of hydrophilic oleophilic ones. The treatment comprises moistening and heating the raw materials in a thermochemical apparatus equipped with a gas flow system, in an oxidizing medium for a period of time. The efficiency of the treatment can be improved by pretreatments of the raw materials, such as by boiling in water, by soaking in acidic or alkaline solution, by mechanically expanding, by adding volatile reagents and by freezing. A special pretreatment of the raw materials with carbonate or bicarbonate results in hydrophilic oleophilic products. The series of the hydrophobic oleophilic and hydrophilic oleophilic products made from different natural substances under various oxidative thermochemical drying conditions have different characteristics and are low-cost, biodegradable, environmentally harmless and widely useful.

Abstract: An oral care implement includes a material that invokes a sensory response when in contact with tissues or surfaces of a mouth of a user. In one embodiment, the material is provided in a two-dimensional or three-dimensional shape indicative of visually communicating the response to the user. The oral care implement may also include a soft tissue cleaner provided with the sensory material.

Abstract: The invention relates to an oxidative thermochemical drying process for changing the hydrophilic and hydrophobic characteristics of organic substances, in particular naturally occurring organic substances, to prepare a new class of hydrophobic oleophilic products, and a new class of hydrophilic oleophilic ones. The process comprises moistening and heating the raw materials in a thermochemical convection apparatus or kiln equipped with a gas flow system, in an oxidizing medium for a predetermined period of time. The efficiency of the treatment can be improved by pretreatments of the raw materials, such as by boiling in water, by soaking in acidic or alkaline solution, by mechanically expanding; by adding volatile reagents and by freezing. One unique pretreatment with carbonate or bicarbonate of the raw materials results in hydrophilic oleophilic bi-functional products.
