Abstract
Systems and methods are disclosed for removing a power supply from a host unit running a computer program, without losing data or causing a cold boot. The present invention employs a retaining assembly for the power supply that delays removal of the power supply until shutting down of the computer program of the host unit. The system may further comprise a logic unit that estimates the period from initiating a power off for the unit, up to an actual shut down of the computer program.
Claims17
A battery cell for use in a battery release mechanism, comprising:
- a first latch mechanism that employs a side latch feature that extends from the exterior of the battery cell, such that when the side latch feature is deflected the side latch feature engages a projection of the battery cell to prevent the battery cell from further removal;
- a second latch mechanism that employs a strip having a wider width at one end and secured via a pin set over a trough, wherein the trough is formed on a surface of the battery cell, the strip is curved to form the projection of the battery cell and the pin set secures the strip;
- wherein upon exerting a downward force, part of the strip moves in to the trough, lowering the projection and disengaging the projection from contacting the side latch feature and releasing the battery cell.
A battery cell contained within a housing for use in a battery release mechanism, comprising:
- a first catch and latch mechanism that employs a pair of buttons extending from the exterior of the battery housing, the buttons includes a flex spring sheet mechanism attached to the interior of the battery housing, the spring sheet deflects when the buttons are displaced such that the buttons engage a projection of the battery cell, wherein upon inward squeezing of the buttons, the first latch and catch mechanism is released allowing the battery to slide out of the host device to a predetermined length;
- a second catch and latch mechanism that employs a notch mounted on a strip, wherein the notch engages with an edge of the host device to create a reactive force that acts in a direction opposite to a sliding direction of the battery cell, by pressing a disc shaped area on the strip, the strip moves downward and lowers the notch from its engaged position allowing sliding out of the battery cell from the housing;
- wherein upon exerting a downward force, part of the strip moves in to the trough, lowering the projection and disengaging the projection from contacting the side latch feature and releasing the battery cell.
A battery cell contained within a battery compartment for use in a battery release mechanism, comprising:
- a latch assembly that includes a latching member and a latch cavity formed on a side wall of the battery compartment, wherein the latching member moves between an extended position and a retracted position;
- a lid hinged to the battery compartment which permits access to the battery compartment;
- wherein in the extended position, the latching member moves parallel to the lid and through a retaining member and locks into the cavity such that the lid is locked, denying access to the battery compartment, and wherein in the retracted position, the latching member moves out of the cavity and retaining member, allowing the battery compartment to be opened and the battery cell removed.
