摘要： A modulator can be configured to sense a change in current flow in a circuit and to generate an oversampled, noise-shaped signal. A first decimation filter is coupled to the modulator and is configured to generate instantaneous current data at a first data rate. The instantaneous current data can be input into a multiplier circuit. The output of the multiplier circuit (the instantaneous current data squared) can be input to a second decimation filter. The second decimation filter can be configured to generate a sum of the squared current data at a second data rate. The sum of the squared current data can be used by an application (e.g., battery power management) to compute power measurements or for other purposes.

摘要： A battery management and protection system can include various features to improve safety-critical and other functions. Among the features that can be included in some implementations are automatic loading of safety or other parameters during start-up of the system; a centralized timekeeper and an event system that can trigger actions in the system independently of a central processing unit; use of the same modules for both automatically-controlled safety-related measurements and firmware-controlled measurements; enhanced diagnostic features, and a sleepwalking feature that allows certain modules in the system to continue to perform various functions even when the module or the system is in a low-power sleep mode.

摘要： In one embodiment, a stylus includes a controller, a delay line, a coefficient line and a computer-readable non-transitory storage medium. The controller is operable to receive a synchronization signal that is transmitted from a computing device and received by the stylus. The delay line is operable to store a first consecutive edges of the synchronization signal. The coefficient line includes a pre-determined coefficient vector. The computer-readable non-transitory storage medium embodies logic that is configured when executed to: determine a first correlation between the first consecutive edges of the synchronization signal and the pre-determined coefficient vector of the coefficient line; remove oldest signal period of edges of the first consecutive edges from the delay line; store next signal period of new consecutive edges of the synchronization signal to the delay line, the new consecutive edges composing a second consecutive edges of the synchronization signal; determine a second correlation between the second consecutive edges of the synchronization signal and the pre-determined coefficient vector; and synchronize one or more timings for communication between the stylus and the computing device based at least in part on the first and second correlations.
