Abstract: A device for measuring a flange in a creased sheet of metal is provided, along with a method of use thereof. The device includes a block including at least two slots and a body extending from the block in a first direction. The device also includes at least two retractable teeth. Each tooth is mounted in a respective one of the at least two slots. Each tooth is biased toward the first direction and retractable in a second direction opposite the first direction. A foot is mounted to an end of the body and includes a groove configured to receive an edge of the sheet of metal. A free edge of the flange is received in the groove and a creased edge is retained by the teeth. The flange may be measured by inserting a depth gauge through the block to a surface of the sheet of metal.

Abstract: A method of upgrading a medical device having a controller that controls operation of the medical device according to an operating routine executed by the controller. Upgrading the medical device includes communicating an external device, such as a conventional computer, with the controller. An external access key is provided to the external device and compared to an internal access key provided by the medical device. Upgrading of the medical device is enabled if the two access keys match. Upgrading includes modifying or rewriting the operating routine stored in the medical device. A medical device manufacturer, supplier, or seller controls the distribution of the external access keys, thereby providing the ability to track the medical devices being upgraded and the upgrade provided to that device.
