A system for wireless generation of at least one standard ECG lead comprises a plurality of electrodes for application to a subject at separate points thereof and a remote receiver station for generating at least one standard ECG lead from signals detected by a first group of said plurality of electrodes. The golf club adjustment tool includes a body having a first clamping portion and a second clamping portion. At least one sliding retainer removably couples the cutting blade to the blade mount and is slidably movable between a locked position and a released position. An elastomeric device is sealingly configured within the activation opening about the activation arm to secure the valve plug in position and bias it distally. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory. This automatic analyzer, therefore, allows information about the reagent ID to be read or written at an arbitrary timing even if the mounting density of reagent containers of the automatic analyzer is increased, thereby improving the function and performance of the apparatus.
