An electrosurgical system is disclosed. The system includes a radio frequency output stage configured to output at least one radio frequency waveform and a current sensor coupled to the output stage and configured to output a first differentiated signal corresponding to a current of the at least one radio frequency waveform, the current sensor coupled to a first conditioning circuit configured to integrate the first differentiated signal to output a processed current signal indicative of the current. The system further includes a voltage sensor coupled to the output stage and configured to output a second differentiated signal corresponding to a voltage of the at least one radio frequency waveform, the voltage sensor coupled to a second conditioning circuit configured to integrate the second differentiated signal to output a processed voltage signal indicative of the voltage, wherein the first and second conditioning circuits have a substantially similar bandpass and phase response.

System and method for voltage and current sensing

A self-contained data acquisition unit is provided for acquiring seismic data. The unit has a microprocessor and an antenna adapted to receive an electromagnetic signal. A decoder is connected with the microprocessor and adapted to convert received electromagnetic signals to dual-tone multiple-frequency ('DTMF') digits. A geophone interface is provided with a geophone for collecting acoustic data incident on the geophone. A memory is connected with the geophone interface for storing a representation of the collected acoustic data and for storing a representation of a reference electromagnetic signal to be used in synchronizing acoustic data collected by other data acquisition units. A battery power source is connected with the microprocessor.

Seismic-data acquisition methods and apparatus

Wireless communications relative to a vehicle using a wireless communications device, a pocket for holding the wireless communication device and an interface module in communication with the pocket are provided. The pocket can include a processor for translating communications between the wireless communications device and the interface module. The interface module has processing capability and can communicate with different pockets and thereby different wireless communications devices. In at least one embodiment, the interface module manages voice recognition and text-to-speech commands to facilitate hands-free communications in the vehicle. The interface module can function as a communications hub involving a number of vehicle subsystems. In a preferred embodiment, the vehicle subsystems are separately addressable using the interface module and/or other processing hardware/software. However, in communicating over the Internet, a vehicle IP address is utilized.
