A monolithic memory array including an NPN emitter follower and low threshold amorphous material storage device at each cell without additional cell isolation. An N-type substrate forms a common collector, a plurality of spaced rows of P-type regions form the bases and a plurality of N-type regions form emitters. The amorphous devices are formed over the space between the P-type regions and are longitudinally aligned with a respective emitter and base contact area.
A surgical light apparatus includes a support arm assembly configured to couple a lighthead to a support surface such as a ceiling, a wall, or a stand. The arm assembly includes an upper arm, a lower arm pivotably coupled to the upper arm and a yolk coupled to the lower arm. The lighthead is pivotable with respect to the yolk which includes a task light. The task light coupled to the yolk assembly provides an auxiliary light source for the room when the surgical light is not in use.
