1. An ultrasound system comprising:
- a generator for generating a driving signal to power an ultrasound transducer assembly;
at least one sensor adapted to sense operating conditions of said generator;
a processor communicating with said sensor;
non-volatile memory coupled to said processor; and
said processor programmed to receive a signal from said sensor during operation of said generator and to store said signal in said memory for access after operation of said generator when said signal indicates a system error, fault or failure;
whereby a history of said faults, errors or failures is available after said generator is powered down.

Abstract
An ultrasound system for providing megasonics and ultrasonics to a liquid at different frequencies and/or sweeping frequencies with associated generators, transducers, operations between resonance and anti-resonance, non-resistive output with phase shift, multiple/sweep/single frequency modes, individually controlled sections, gate drive power control, variable inductive compensation for temperature changes, parallel inductor matching, stacked ceramics and non-volatile memory storage of fault, error and failure history.

8. An ultrasound system comprising:
-
an electronic bridge circuit that provides an operational ultrasound frequency or operational bandwidth of frequencies and has a first output terminal and a second output terminal configured to provide an output voltage and an output current; a phase shift network having a first input terminal, a second input terminal, a first output terminal and a second output terminal; said first output terminal of said electronic bridge circuit coupled to said first input terminal of said phase shift network and said second output terminal of said electronic bridge circuit coupled to said second input terminal of said phase shift network; an ultrasound transducer having a first input terminal and a second input terminal, said first output terminal of said phase shift network coupled to said first input terminal of said ultrasound transducer and said second output terminal of said phase shift network coupled to said second input terminal of said ultrasound transducer; at least one sensor adapted to sense operating conditions of said ultrasound system; a processor communicating with said sensor; non-volatile memory coupled to said processor; said electronic bridge circuit, said phase shift network and said ultrasound transducer configured such that said output voltage leads said output current by an angle that is greater than 0 degrees and less than about 90 degrees for said operational ultrasound frequency or bandwidth of frequencies; and said processor programmed to receive a signal from said sensor during operation of said ultrasound system and to store said signal in said memory for access after operation of said ultrasound system when said signal indicates a system error, fault or failure; whereby a history of said faults, errors or failures is available after said ultrasound system is powered down. - View Dependent Claims (9, 10, 11, 12, 13, 14)
