Abstract: A signal processing module includes an input module electronically coupled to a sensing probe of a nerve integrity monitoring system. The probe senses electrical signals from a patient during operation of an electrosurgical unit. The input module receives an input signal from the probe. An EMG detection module is coupled to the input module and is adapted to detect conditions in the input signal. The conditions are classified as a function of a level of electromyographic activity. An output module, coupled to the EMG detection module, provides an indication of electromyographic activity in the input signal based on the detected conditions.

Abstract: A data capturing module combined with a portable data terminal of the hand-held type to record handwritten data. Using a digitized pad, the module can provide for direct input of handwritten data into the system, or a peripheral digital scanner can be employed to provide for data entry. Depending upon the particular application, the module therefore provides for data entry of handwritten text or graphics using the data terminal and other components of a portable data system to enter, display, print or otherwise communicate the handwritten data.

Abstract: An intraoperative neural monitoring system includes a power source and a simulator powered by the power source to deliver a cycle of electrical stimulation to a patient as a first group of positive or negative phase pulses automatically followed by a second group of pulses of opposite phase or polarity to the pulses of the first group. An activation performed to initiate delivery of the first group of pulses is effective to deliver the entire cycle of stimulation. A method of intraoperative neural monitoring involves activating a simulator to deliver a biphasic cycle of electrical stimulation to a patient during an operative procedure, delivering the entire cycle of electrical stimulation to the patient in response to the activating step and detecting EMG activity in the patient.

Abstract: A versatile data handling apparatus providing multiple alternatives for inputting data is disclosed. The apparatus includes an array of depressible keys, a screen-based input system that is located distinctly from the depressible keys, an optical information sensing component and a visual display to present visual information to a user. The data input activities are coordinated by a computerized data handling system communicatively coupled with the various components.

Abstract: An economically manufactured, highly sensitive, noise and interference resistant, AC powered, two, four or eight channel intraoperative neuroelectrophysiological monitor includes a mainframe having a touch panel display and a low noise interface cable providing connection via a patient interface box for one or more stimulator probes and one or more EMG signal sensing electrodes.

Abstract: A hand-held bipolar electrical stimulus probe includes first and second insulated conductors having unequal diameters and a stable side-by-side orientation. The conductors are provided with visually perceptible indicia such as color coding for identification. The conductors are carried within a flexible jacket and the terminal portions thereof are deformable. The conductors are each insulated substantially up to their tips to prevent current shunting. The probe may include a momentary contact switch permitting selective monopolar or bipolar operation.

Abstract: In a system including volatile memory, a battery backed memory may be available for preserving data in the event of a power failure. Low power condition is reliably sensed sufficiently in advance of supply voltage falling below a minimum operating voltage range so as to give an adequate time interval, e.g. 2.5 milliseconds for the saving of application operating system status. By using a voltage regulator signal which switches in a particularly sensitive manner toward a saturation or zero state well outside its normal control range to trigger a low power signal, such low power signal may provide a time interval of, e.g. from three to six milliseconds of advance warning of impending supply voltage failure.

Abstract: In an exemplary embodiment, a battery conditioning system monitors battery conditioning and includes a memory for storing data based thereon; for example, data may be stored representative of available battery capacity as measured during a deep discharge cycle. With a microprocessor monitoring battery operation of a portable unit, a measure of remaining battery capacity can be calculated and displayed. Where the microprocessor is permanently secured to the battery so as to receive operating power therefrom during storage and handling, the performance of a given battery in actual use can be accurately judged since the battery system can itself maintain a count of accumulated hours of use and other relevant parameters. Where an embodiment includes a main battery and a backup battery, the voltage of each may be individually measured, and each may be conditioned. Battery capacity of each may be measured.
