An example computing system may include a display and an input device. The input device may include a touch sensor to provide touch data, and a contactless sensor to provide contactless data. A field of view of the contactless sensor is directed away from the touch sensor. A controller is to combine the touch data and the contactless data into combined data to generate a virtual hand to be displayed on the display. The virtual hand is to include an unsensed feature.

A sheet feed mechanism having a multi-layer structure. The multi-layer structure has a wear layer adapted to contact a sheet during sheet feeding and a replacement indicator layer adjacent the wear layer. The replacement indicator layer is adapted to indicate a wear condition of the multi-layer structure upon wear through the wear layer to the replacement indicator layer.

A machine and method for making a strip of dome arrays on a backup strip, wherein the dome arrays include a plurality of domes in a predetermined non-linear pattern and in oriented relation to each other that are adhesively mounted on a dome seal. The machine comprises a punch press or stamping machine capable of simultaneously stamping a pattern of domes in non-linear arrangement and oriented relative to each other and depositing those domes onto the adhesive side of a dome seal strip. The machine also includes means for feeding dome seals to the stamping machine and also for kiss-cutting the dome seal while on the backup strip to define a plurality of successively arranged dome arrays.

A unique electrode assembly primarily designed to pass an induced current through a liquid phase by transfer of molecules adsorbed on sub-micron charged particles from cathode to anode to enable conductance determinations on non-polar liquids, for example, hydrocarbon oils that have been altered while in the molecular state to enable a degree of polarity. The novel electrode assembly comprises a cylinder within a cylinder configuration, the outer cylinder containing orifices equalizing area for largest electrode area within smallest liquid volume. A one millimeter gap enables increased more accurate, electrode component signal representations. A magnetic means is provided for nullifying electro-magnetic fields induced in electrode assemblies where the liquid is non-polar containing molecules oriented to conductive polar state by additives such as sub-micron particles and the induced field will cause polar disorientation with lowered conductivity. High gauss permanent magnets are placed so their field is through the electrodes axis and at a ninety degree angle with respect to the electrodes electro-magnetic field, thus maintaining the molecules additive induced polar conductivity.

A method of measuring relatively small amounts of saturated hydrocarbon oil in an essentially nonconductive liquid, comprises the steps of mixing the oil and liquid with a conductivity additive such as colloidal metal-containing particles to render the oil conductive without rendering the nonconductive liquid conductive and then measuring an electric current passed through the mixture to obtain an indication of the amount of oil in the mixture. The metal-containing particles may for example be selected from the group consisting of chromium dicarbide, chromium silicide and silver peroxide.

A method of measuring relatively small amounts of hydrocarbon oil contained in water, or other immiscible liquids including mixing a solvent and a conductivity additive with the oil and water or immiscible liquid, hereinafter termed 'water' as it will be the most prevalent use, to form a mixture. The solvent is water rejecting and extracts the oil from the water. A method of producing a chemo-conductivity additive to render the electrically non-conductive oil of the mixture electrically conductive without rendering the solvent conductive or adding to any existing water conductivity. The amount of oil is electronically ascertained by measuring the conductivity of an electrical current passed through the mixture after the oil has been rendered conductive. A novel apparatus is provided to perform the process. The apparatus comprises all the elements for carrying out the process including a separating funnel, measuring beaker, electrode assembly, electronics assembly and both analog and digital displays. In particular, the unique electrode assembly is specially designed to enable conductivity measurement of the electrically conductive-rendered oil.
