Abstract: There is disclosed a keypad apparatus and a method for determining the status of a keypad apparatus. In one embodiment, the keypad apparatus includes a keypad having a plurality of keys and a keypad matrix associated with the keypad and having a switch. The keypad apparatus also includes a cover moveable between an open and a closed position. The keypad apparatus still further includes a means for engaging that cooperates with and allows the switch to provide a status indicating a position of the cover.

Abstract: A method for the preparation of a two-phase magnetic material that includes as the major phase a crystalline alloy of one or more rare earth metals, boron and iron, substantially all of the crystallites of which have a size of less than 35 nanometers, and as the minor phase .alpha.-Fe, involves the steps of (i) melt spinning an alloy consisting of up to 12 atomic percent of one or more rare earth metals, 3 to 7 atomic percent of boron and the balance iron or a mixture of iron and cobalt; (ii) quenching the melt spun alloy form step (i) under conditions such that a mixture of crystalline and amorphous material is produced, (iii) subjecting the material from step (ii) to an annealing treatment under conditions such that controlled crystal growth occurs to provide the crystalline alloy phase, substantially all of which has a particle size of less than 35 nanometers, the resulting materials having a remanence in excess of the theoretical value of 0.8 Tesla.
