Biopsy driver assembly having a control circuit for conserving battery power
First Claim
1. A method for conserving battery power in a biopsy apparatus having a battery, a motion detector, a timer 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 comprising:
- 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.

7. A method for conserving battery power in a medical apparatus comprising:
-
supplying a biopsy apparatus having a biopsy driver assembly configured to mount a biopsy probe assembly, the biopsy driver assembly comprising a biopsy driver housing, a motion detector, a timer circuit, a probe presence circuit, and a battery dwell circuit;
an electrical assembly coupled to the biopsy driver housing, the electrical assembly including at least one electrical drive configured for drivably engaging the biopsy probe assembly;
a battery coupled to the biopsy driver housing;
the biopsy driver assembly having an operative mode wherein electrical power is supplied to the electrical assembly when a physical movement of the biopsy driver assembly is detected by the motion detector;
the biopsy driver assembly having a battery dwell mode wherein electrical power is supplied to the motion detector to the exclusion of the timer circuit and the electrical assembly after a predetermined time following the last detected physical movement of the biopsy driver assembly;de-activating the motion detector when the probe presence circuit determines that the biopsy probe assembly is not mounted to the biopsy driver assembly such that neither the operative mode nor the battery dwell mode is operational; and bypassing the probe presence circuit based on a user input to activate the motion detector and to cause the battery dwell circuit to enter the operative mode in an absence of the biopsy probe assembly being mounted to the biopsy driver assembly. - View Dependent Claims (8, 9, 10, 16)

11. A method for conserving battery power in a biopsy apparatus:
-
the biopsy apparatus comprising a battery, a motion detector, a timer circuit, a probe presence 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 biopsy driver assembly further comprising an operative mode wherein electrical power is supplied to the electrical assembly when the physical movement of the biopsy driver assembly is detected by the motion detector, and the biopsy driver assembly further comprising a battery dwell mode wherein electrical power is supplied to the motion detector to the exclusion of the timer circuit and the electrical assembly after a predetermined time following the last detected physical movement of the biopsy driver assembly; and the method comprising; de-activating the motion detector when the probe presence circuit determines that the biopsy probe assembly is not mounted to the biopsy driver assembly such that neither the operative mode nor the battery dwell mode is operational; and bypassing the probe presence circuit based on a user input to activate the motion detector and to enter the operative mode in an absence of the biopsy probe assembly being mounted to the biopsy driver assembly. - View Dependent Claims (12, 13, 14, 15)
