Abstract of the Patent Summary "Staple cartridge tissue thickness sensing system" In various embodiments, a staple cartridge for use in a surgical stapler is disclosed. the staple cartridge comprises a staple body comprising a proximal end and a distal end. a tissue thickness sensing module is positioned adjacent the distal end of the staple body. The tissue thickness detection module comprises a controller and a sensor. a power switch is removably located adjacent the staple body. The controller is configured to detect the power switch and to keep the tissue thickness sensing module in a low power state while the power switch is present. When the power switch is removed, the controller changes the tissue thickness detection module to an active state. 2/2abstract in various embodiments, a staple cartridge for use in a surgical stapler is disclosed. the staple cartridge comprises a staple body comprising a proximal end and a distal end. a tissue thickness sensing module is positioned adjacent to the distal end of the staple body. the tissue thickness sensing module comprises a controller and a sensor. a power key is located removably adjacent to the staple body. the controller is configured to detect the power key and to maintain the tissue thickness sensing module in a low-power state while t
