| 20100271003 | Nanotube Resonator Devices - A fully-functional radio receiver fabricated from a single nanotube is being disclosed. Simultaneously, a single nanotube can perform the functions of all major components of a radio: antenna, tunable band-pass filter, amplifier, and demodulator. A DC voltage source, as supplied by a battery, can power the radio. Using carrier waves in the commercially relevant 40-400 MHz range and both frequency and amplitude modulation techniques, successful music and voice reception has been demonstrated. Also disclosed are a radio transmitter and a mass sensor using a nanotube resonator device. | 10-28-2010 |
| 20100308791 | SINGLE ELEMENT THREE TERMINAL PIEZORESISTIVE PRESSURE SENSOR - Embodiments of the invention provide for three-terminal pressure sensors (“3-TPS”), a method of measuring a pressure with a 3-TPS, and a method of manufacturing a 3-TPS. In some embodiments, the 3-TPS includes a semiconducting layer with cavity and a 3-TPS element having at least one piezoresistive layer overlapping at least a portion of the cavity and oriented at an angle selected to provide a desired sensitivity for the 3-TPS. The method of measuring a pressure with a 3-TPS is performed with a 3-TPS that includes an input terminal, first and second output terminals, and a 3-TPS element, the 3-TPS element overlapping at least a portion of a cavity at a predetermined angle. The method comprises providing an input signal to the input terminal of the 3-TPS, determining a difference between two output signals from the respective output terminals of the 3-TPS, and correlating the determined difference to a pressure. | 12-09-2010 |

| 20120286765 | IDENTIFYING HEARING PROSTHESIS ACTUATOR RESONANCE PEAK(S) - An auditory prosthesis comprising an actuator for providing mechanical stimulation to a recipient. The auditory prosthesis comprises a measurement circuit for use in determining the resonance peak(s) of the actuator. In an embodiment, the measurement circuit measures the voltage drop across the actuator and/or current through the actuator during a frequency sweep of the operational frequencies of the actuator. These measured voltages and/or currents are then analyzed for discontinuities that are indicative of a resonance peak of the actuator. In another embodiment, rather than using a frequency sweep to measure voltages and/or currents across the actuator, the measurement circuit instead applies a voltage impulse to the actuator and then measure the voltage and/or current across the actuator for a period of time after application of the impulse. The measured voltages and/or currents are then analyzed to identify resonance peak(s) of the actuator. | 11-15-2012 |
