Improved assemblies, systems, and methods provide safeguarding against tissue injury during surgical procedures and/or identify nerve damage occurring prior to surgery and/or verify range of motion or attributes of muscle contraction during reconstructive surgery. A stimulation control device may incorporate a range of low and high intensity stimulation to provide a stimulation and evaluation of both nerves and muscles. A stimulation control device is removably coupled to a surgical device or is imbedded within the medical device to provide a stimulation and treatment medical device. A disposable hand held stimulation system includes an operative element extending from the housing, the housing includes a visual indication to provide feedback or status to the user.

Neurostimulation assemblies, systems, and methods make possible the providing of short-term therapy or diagnostic testing by providing electrical connections between muscles or nerves inside the body and stimulus generators or recording instruments mounted on the surface of the skin or carried outside the body. Neurostimulation assemblies, systems, and methods may include a carrier and a removable electronics pod, the electronics pod including stimulation generation circuitry, a power input bay to hold a disposable power source, and user interface components. The assemblies, systems, and methods are adapted to provide coordinated neurostimulation to multiple regions of the body.

A driver circuit for an electronic switch, the driver circuit having a first input for receiving a first control signal, and a second input for receiving a signal from a current sensor, the driver circuit further including a shut-off circuit for operating the electronic switch to cause an interruption to current flow in the event of a fault condition arising, such as current through the electronic switch exceeding a predetermined threshold, wherein operation of the shut-off circuit can be invoked by a predetermined event at the first input.

Driver circuit

An isolated-ADC and a method for providing isolated analog-to-digital conversion are disclosed. The isolated-ADC includes a microelectromechanical system (MEMS), a comparator, and a digital-to-analog converter (DAC). The MEMS includes a beam element supported from a substrate for movement with respect to an axis, first and second actuators and a sensor. The first and second actuators are capable of exerting respective forces upon the beam element causing the beam element to move in response to analog input and feedback signals, respectively. The sensor detects changes in position of the beam element and produces a position signal indicative thereof. The comparator generates a digital signal based upon a comparison of the position signal with a reference value. Based on the digital signal, the DAC generates the feedback signal, and the isolated-ADC produces a digital output signal.

A capacitance comparison circuit determines the relative value of two capacitors, such as may be sensor elements, by monitoring voltage changes caused by charge redistribution between the capacitors when they are series connected and then connected alternately in a first and second polarity across a voltage. The direction of change of voltage at the junction of the capacitors with respect to the switching of polarity of their connection precisely reveals which capacitor is larger. Disconnecting the voltage monitor during the switching reduces switching induced errors.

Highly sensitive capacitance comparison circuit

A programmable analog I/O circuit for use in an industrial control system has a first mode of operation as an input circuit and a second mode of operation as an output circuit. In the first mode of operation, a device-side I/O terminal is adapted for receiving an analog input status signal from an analog input device. In the second mode of operation, the device-side I/O terminal is adapted for transmitting an analog output control signal to an analog output device. According to another aspect, a programmable I/O circuit that drives an output device in an industrial control system comprises a plurality of configurable gain stages and a plurality of programmable isolating links. The plurality of programmable isolating links are coupled to the plurality of configurable gain stages and are programmable to determine a series or parallel arrangement of the plurality of configurable gain stages. The output control signal produced by the parallel arrangement is a high current, low voltage output signal as compared to the output control signal produced by the series arrangement. According to another aspect, an integrated circuit fabricated on a single semiconductor chip comprises an I/O interface, a control/logic circuit, and a communication interface. The integrated circuit may be advantageously used to provide a highly distributed industrial control system in which control is distributed all the way to the device level.
