    摘要： A power tool system component has a microprocessor, a one wire communication terminal connecting the microprocessor to an external device, and a flash memory storing: (a) an application program governing operation of an application mode during which the power tool system component is operated; and (b) a boot loader program governing operation of a boot loader mode during which at least part of the application program can be updated. The microprocessor accesses the flash memory and implements the boot loader program and the application program by setting up and observing a temporal window during which one or more predetermined conditions must be met for the boot loader mode to be entered. The predetermined conditions include successful completion of a calibration process that includes sending a calibration byte to the external device according to a format predetermined to allow the external device to adjust its baud rate for sending and receiving information. Upon successful completion of the conditions within the temporal window, the microprocessor sends a confirmation to the device that the conditions have been satisfied and enters the boot loader mode.

    摘要： A method and system for authenticating a smart battery having a smart battery and an electronic device. Both the device and the smart battery generate encrypted random strings using key material based by A/D noise bits as a seed value. A pseudo random number is generated from the A/D noise that is transmitted to both the electronic device and the smart battery. The pseudo random number is used by both devices as a key index to select one of a plurality of keys stored in separate key libraries. The keys, or key material, is used to execute an encryption algorithm. The two encryption data streams are then compared to authenticate the smart battery.

In an, the battery pack of the cordless system is capable of multiple modes, such as controlling the cordless device and controlling the charger. In an aspect, the battery pack validates the cordless device or charger to which it is mated in an aspect of the invention, the cordless system uses any of a wired interface, radio frequency interface, an optical interface or a magnetic interface to communicate information between the battery pack and the cordless device or charger to which the battery pack is mated. In an aspect, female terminals are used in a terminal block of the battery pack to protect against foreign objects contacting the terminals. In aspect, the terminals in the terminal block of the battery pack are staggered or scattered to reduce the likelihood of a short circuit. In an aspect of the invention, the battery pack has a trap door that closes when the battery pack is not mated to a cordless device or charger to protect the terminal block of the battery pack. In an aspect of the invention, multi-spring, split contact terminals are used in the terminal block of at least one of the cordless system components. In an aspect of the invention, the battery cells are Lithium Ion battery cells.
