A computer triangulates the location of the pen versus time to generate the signature shape, and to generate velocity and acceleration data. The pen also includes a pressure sensitive tip to record pressure applied to the pen tip. The pen also includes a higher frequency burst transmitter useful to generate a time reference, and to transmit the pressure information. The computer packetizes the shape, velocity, acceleration, and pressure data with a time stamp and an IP address or phone number, encrypts the packet and sends it to a host computer for authentication.

Abstract: A resonance suppression circuit is provided to suppress resonance on a power grid of a chip or die. The resonance suppression circuit may include a band-pass filter portion, a comparator portion, an amplification portion and a current dissipation portion. The band-pass filter portion may include an inverter coupled between two signal lines of the power grid. The comparator portion may sense voltage fluctuations at approximately the resonance frequency and trigger the current dissipation portion to turn ON and thereby change the frequency spectrum of the load current on the power grid to suppress the power grid resonance.

Abstract: An AC-to-DC converter for converting an AC voltage to a DC voltage includes a first converter, a second converter, a sense circuit, a controller, and an enabling circuit. The first converter converts an AC voltage to a first DC voltage. The second converter converts the first DC voltage to a second DC voltage. The sense circuit coupled to the first and second converters provides a first sense signal indicative of the first DC voltage and a second sense signal indicative of the AC voltage. The controller coupled to the first and second converters controls the first and second DC voltages. The enabling circuit coupled to the sense circuit generates a control signal to the controller to disable both the first converter and the second converter by comparing the first sense signal to a first threshold voltage and comparing the second sense signal to a second threshold voltage.
