Electrical nerve stimulation device
First Claim
1. A nerve stimulation device comprising:
- at least one output channel capable of communicating a generated electrical pulse signal to a user, the at least one output channel being operably coupled to at least one lead wire for delivering the generated electrical pulse signal;
a processor performing open lead monitoring for the at least one output channel to sense changes in the delivery to the user of the generated electrical pulse, and adjusting the electrical pulse signal to a low polling level signal upon detecting an open lead condition; and
non-volatile memory in operable communication with the processor for storing data, wherein the non-volatile memory includes EEPROM memory capable of storing operating parameter data for the device prior to power shut down of the device.

Abstract
The electrical nerve stimulation unit in accordance with the present invention generally includes a housing, an input panel, a display panel, a controller, a first channel output, a second channel output, and a power system. While the device is generally described in terms of use as a TENS unit, it must be noted that other nerve stimulation applications for the device are envisioned as well. The myriad of intelligent and proactive programmable software functions and features of the present invention are executed on the controller'"'"'s microprocessor. For instance, open lead monitoring, soft recovery implementation, compliance monitoring, and enhanced power management are all controlled and monitored through the interfacing of the processor with the various devices and hardware on the unit'"'"'s hardware platform.
