摘要： A process for forming a hermetic glass-to-metal seal between a conductive pin and an outer body, wherein a corrosion-resistant noble metal (e.g., gold) coating is applied to the conductive pin before the hermetic seal is formed. The process generally includes providing a noble metal-coated conductive pin, placing glass having a softening point less than about 650.degree. C. into a cavity of the outer body, inserting the coated conductive pin into a bore in the glass preform, heating the assembly to a temperature in excess of the softening point of the glass but less than about 700.degree. C., and cooling the assembly. The coefficients of thermal expansion of the components of the assembly are preferably selected such that the resulting assembly is a hermetic compression seal.

摘要： A matrix keyboard system for producing key codes in response to the actuation of key switches. The keyboard system includes ghost key condition detection. In the keyboard system, a group of parallel drive lines and a group of orthogonal parallel sense lines form a matrix, with a key switch being associated with each of the intersection points on the matrix. The drive lines are sequentially activated, and the actuation of a key switch along an activated drive line results in the coupling of a drive signal to the associated sense line. A ghost key condition arises when three of the four corners of a notional rectangle in the matrix contain an actuated key switch. The ghost key condition detector senses the presence of drive signals not only on the sense lines but also on the drive lines, with a ghost key condition being identified if a drive signal is sensed on two or more sense lines and two or more drive lines simultaneously.
