Abstract
A method for conserving battery power in a biopsy apparatus having a battery, a motion detector, a timer circuit, a battery dwell circuit, and a biopsy driver assembly configured to mount a biopsy probe assembly, the biopsy driver assembly comprising an electrical assembly including at least one electrical drive configured for drivably engaging the biopsy probe assembly, the method including conserving the battery by turning off electrical power both to the timer circuit and to the electrical assembly after a predetermined time as determined by the timer circuit following a last detected physical movement of the biopsy driver assembly; and turning on electrical power from the battery to the timer circuit and to the electrical assembly when a physical movement of the biopsy driver assembly is detected.
