A MEMS vapor bubble generator includes a chamber for holding liquid; and a heater positioned in the chamber, the heater being formed using a sputtering technique. The heater is formed from a superalloy material. The superalloy material of the heater is in direct contact with the liquid, without any intervening protective coating. The superalloy has a crystalline structure with a grain size less than 100 nano-meters. The superalloy is MCrAlX, where M is one or more of Ni, Co, Fe with M contributing at least 50% by weight, Cr contributing between 8% and 35% by weight, Al contributing more than zero but less than 8% by weight, and X contributing less than 25% by weight, with X consisting of zero or more other elements, preferably including but not limited to Mo, Re, Ru, Ti, Ta, V, W, Nb, Zr, B, C, Si, Y, Hf.

A method of enabling entry of data into a computer system via a printed form is provided. The method comprises the steps of: (i) providing the printed form, the form containing human-readable information and machine-readable coded data, the coded data being indicative of an identity of the form and of a plurality of locations on the form; (ii) operatively positioning a sensing device relative to the form; (iii) sensing at least some of the coded data; (iv) generating indicating data using the sensed coded data, the indicating data being indicative of the identity of the form and the position of the sensing device relative to the form; and (v) sending the indicating data to a computer system, thereby enabling the computer system to identify the data for entry. The coded data comprises an ink composition containing an IR-absorbing dye and a singlet oxygen quencher.
