摘要:
An electrotherapy system for stimulating sensory nerves within skin tissue includes a electrode carrier, a pulse generator, an array of skin-penetrating electrodes and surface skin electrodes, a pulse conditioning circuit, and a power source. The system administers biphasic pulsed current at the surface skin electrodes and monophasic pulsed current at each skin-penetrating electrode. The skin-penetrating surfaces and skin contact surfaces of the electrotherapy system may be sterilized or may be replaceable for outpatient reusability.

摘要:
A multi-functional portable electro-medical device provides interferential current stimulation to promote bone growth. Two electrical signals are applied to a target area, each electrical signal being formed by a set of two electrode pads. A beat frequency is created at the location the signals intersect with each other. The beat frequency is the difference between the frequencies of the two signals and has an amplitude that is additive and greater than either signal alone. The depth of the interferential signal is increased by increasing the carrier frequency of the signals. The direction of the interferential signal shifts toward the signal having the lower amplitude. The electrical stimulation is used in combination with biologics to further increase bone growth.

摘要:
A stimulator and a method for electrical stimulation of bone to promote osteogenesis is disclosed in which surface electrodes positioned around an incision site transmit an interferential current that has a base medium frequency alternating current between 1K-20 KHz. A digital signal processor generates a sine-wave-like waveform from a pulse generator which after further processing is used to generate two circuits for use in producing the interferential current. The effective area of stimulation is controlled by placement of electrodes and electrode orientation. Amplitude modulation of electrical circuits created at the electrode placements also augments the effective area of stimulation.

An orbital mission planning indicator device provides a visual indication of the relationship between the plane of orbit of an artificial earth satellite and the angle of incidence of solar energy thereon, for all seasons of the year and for arbitrary times and places of launch of such satellite. It also provides indications of the relationship of deep space points of interest to the same orbital plane for adaptability of pointable sensors such as telescopes, antennas and solar arrays to orbital missions calling for use of such equipments.

An apparatus and method for improving mobility and/or the quality of synovial fluid of an affected articular joint are disclosed, wherein the joint is associated with at least a first muscle group and at least a second muscle group each having an antagonistic relationship for effecting mobility of the joint through a range of motion when recruited by natural neural impulses. The apparatus and method include an electro-medical device configured to apply motor-level electrical stimulation in a multiphasic pattern via at least a first channel and at least a second channel, the multiphasic pattern being programmed into the electro-medical device and corresponding to the sequence of an electromyographic output for the joint; at least two first electrodes connected to the at least first channel of said electro-medical device, the at least two first electrodes being positioned proximate to the at least first muscle group; at least two second electrodes connected to the at least second channel of said electro-medical device, the at least two second electrodes being positioned proximate to the at least second muscle group; and an applicator configured to be worn on the articular segment such that the at least two first electrodes and the at least two second electrodes are disposed between the applicator and the articular segment, the applicator being further configured to reduce compressive forces on at least one compartment of the affected joint.
