| 20080231361 | MOLECULAR TRANSISTOR CIRCUITS COMPATIBLE WITH CARBON NANOTUBE SENSORS AND TRANSDUCERS - Small-signal and other circuit design techniques realized by carbon nanotube field-effect transistors (CNFETs) to create analog electronics for analog signal handling, analog signal processing, and conversions between analog signals and digital signals. As the CNFETs exist and operate at nanoscale, they can be readily collocated or integrated into carbon nanotube sensing and transducing systems. Such collocation and integration is at, or adequately near, nanoscale. | 09-25-2008 |
| 20080290941 | NANOELECTRONIC DIFFERENTIAL AMPLIFIERS AND RELATED CIRCUITS HAVING CARBON NANOTUBES, GRAPHENE NANORIBBONS, OR OTHER RELATED MATERIALS - Small-signal and other circuit design techniques realized by carbon nanotube field-effect transistors (CNFETs) to create analog electronics for analog signal handling, analog signal processing, and conversions between analog signals and digital signals. As the CNFETs exist and operate at nanoscale, they can be readily collocated or integrated into carbon nanotube sensing and transducing systems. The resulting collocation and integration may be at, or adequately near, nanoscale. One embodiment implements an analog differential amplifier having transistors which include carbon nanotubes, electrical contacts, and insulating material. The differential amplifier may be used in isolation or as an element of an operational amplifier. Negative feedback may be used to implement a wide range of analog signal processing functions, and to provide conversions among analog and digital signals. In some cases, an entire analog differential amplifier is implemented with a single carbon nanotube. | 11-27-2008 |
| 20080315967 | VARIABLE PULSE-WIDTH MODULATION WITH ZERO D.C. AVERAGE IN EACH PERIOD - Pulse-width modulation (PWM) finds wide use in many applications including motor control, communication systems, music synthesizers, power supplies, class-D and digital amplifiers, among others. The Fourier series expansion of each period of a pulse waveform includes an additive term that is a function of the pulse width in that period. As the pulse width is varied, this additive term varies, which can be problematic in many applications. In an embodiment, a single-pulse per period pulse width modulated waveform comprising a zero d.c. term in each period regardless of pulse width is generated. In various realizations these waveforms may be generated by electronic circuitry without the use of capacitive coupling or may be generated by algorithms. Further aspects include “through-zero” pulse width modulation and zero-centered asymmetric triangle waveforms and use in instrumentation for measurement of a phase angle of an exogenous system or phenomena. | 12-25-2008 |
| 20090052794 | COMPUTING ARBITRARY FRACTIONAL POWERS OF A TRANSFORM OPERATOR FROM SELECTED PRECOMPUTED FRACTIONAL POWERS OF THE OPERATOR - A computer-implemented system and method for correcting misfocus in original particle beam image data by using a fractional Fourier transform operation or an approximation of it. In one embodiment, the particle beam image data is produced by an electron microscope. The approximation of a fractional Fourier transform operation may comprise a portion of a Taylor series expansion, a Hermite function expansion, a perturbation approximation, a singular integral approximation, or an infinitesimal generator. The described embodiments provide for the reconstruction of phase information associated with the original image data, and for the reconstructed phase information to also utilize an approximation of a fractional Fourier transform operation. The focus correction can be selected and controlled by user interaction or an automatic feedback control system that may include optimization. | 02-26-2009 |
