Patent number: 12023491Abstract: A microcurrent treatment device has one or more electrodes or emitters configured for electrical communication with the surface of a subject's skin. A voltage or current supply is adapted to generate an electrical waveform or other energetic waveform for application to the skin surface, via the one or more electrodes or emitters, and a controller is configured to modulate the waveform. The controller can modulate consecutive pulses of the waveform so that the pulse width, period, frequency, amplitude or integrated amplitude of the consecutive pulses varies in a predefined, random, pseudorandom, or other aperiodic manner, or so that the pulses exhibit a degree of statistical randomness, over a predefined period. The period can cover a set of consecutive pulses defining a treatment cycle, or a continuous subset of consecutive pulses defining one or more phases of a treatment cycle.Type: GrantFiled: April 2, 2021Date of Patent: July 2, 2024Assignee: NSE Products, Inc.Inventors: Dale G. Kern, DucToan Thanh Doan

Patent number: 6337884Abstract: The present invention allows for the simultaneous transmission of two digital signals from one integrated circuit to another. The two digital signals are encoded utilizing a voltage divider circuit and are then transmitted by one transmission line to the second integrated circuit chip. The second integrated circuit chip decodes the first digital signal and then utilizes this decoded digital signal to further decode the second digital signal.Type: GrantFiled: June 12, 1998Date of Patent: January 8, 2002Assignee: International Business Machines CorporationInventors: Tai Cao, Satyajit Dutta, Thai Quoc Nguyen, Thanh Doan Trinh, Lloyd Andre Walls

Patent number: 5789937Abstract: A driver circuit including of one or more fingers, or parallel driver circuits, senses for an overshoot or an undershoot condition of the signal transmitted onto a transmission line coupled to the driver circuit and compensates for such an overshoot or an undershoot by temporarily turning off the offending transition portion of the driver circuit, or finger portion. This is accomplished by turning off the transistor applying one of the two supply voltages coupled to the output transmission line. Effectively, the compensation circuitry within the driver circuit more closely matches the output impedance of the driver circuit to the impedance on the driven transmission line.Type: GrantFiled: August 14, 1996Date of Patent: August 4, 1998Assignee: International Business Machines CorporationInventors: Tai Any Cao, Satyajit Dutta, Thai Quoc Nguyen, Pee-Keong Or, Thanh Doan Trinh, Lloyd Andre Walls

Patent number: 5663663Abstract: The present invention facilitates communication of signals from circuitry implemented with a first CMOS technology requiring a first voltage level supply for operation to circuitry implemented with a second CMOS technology requiring a second voltage level supply for operation, wherein the first and second voltage level supplies are not equal. The present invention receives from the circuitry implemented with a first CMOS technology a signal which has a first voltage level that is not acceptable for input into the circuitry implemented with a second CMOS technology. This signal is converted to a second voltage level that is acceptable for input into the circuitry implemented with a second CMOS technology, and then transmitted to the circuitry implemented with a second CMOS technology requiring a second voltage level supply for operation.Type: GrantFiled: April 26, 1996Date of Patent: September 2, 1997Assignee: International Business Machines CorporationInventors: Tai Cao, Satyajit Dutta, Thai Quoc Nguyen, Thanh Doan Trinh, Lloyd Andre Walls
