20090002914 | Variable capacitor tuned using laser micromachining - A variable capacitor device is disclosed in which the capacitive tuning ratio and quality factor are increased to very high levels, and in which the capacitance value of the device is tuned and held to a desired value with a high level of accuracy and precision using a laser micromachining tuning process on suitably designed and fabricated capacitor devices. The tuning of the variable capacitor devices can be performed open-loop or closed-loop, depending on the precision of the eventual capacitor value needed or desired. Furthermore, the tuning to a pre-determined value can be performed before the variable capacitor device is connected to a circuit, or alternatively, the tuning to a desired value can be performed after the variable capacitor device has been connected into a circuit. | 01-01-2009 |
20120301981 | METHOD FOR THE FABRICATION OF ELECTRON FIELD EMISSION DEVICES INCLUDING CARBON NANOTUBE FIELD ELECTRON EMISSON DEVICES - The present invention is directed to a method for the fabrication of electron field emitter devices, including carbon nanotube (CNT) field emission devices. The method of the present invention involves depositing one or more electrically conductive thin-film layers onto a electrically conductive substrate and performing lithography and etching on these thin film layers to pattern them into the desired shapes. The top-most layer may be of a material type that acts as a catalyst for the growth of single- or multiple-walled carbon nanotubes (CNTs). Subsequently, the substrate is etched to form a high-aspect ratio post or pillar structure onto which the previously patterned thin film layers are positioned. Carbon nanotubes may be grown on the catalyst material layer. The present invention also described methods by which the individual field emission devices may be singulated into individual die from a substrate. | 11-29-2012 |

20090311972 | SYNTHESIZER AND MODULATOR FOR A WIRELESS TRANSCEIVER - A transceiver including a transmit modulator and a receiver. The modulator may accept a channel selection input, a first modulation input, a second modulation input, and an amplitude input. During transmit time slots, the modulator may generate a modulated output having a carrier frequency selected by the channel selection input. The carrier frequency may be frequency modulated by the first modulation inputs, phase modulated by the second modulation input, and amplitude modulated by the amplitude input. During receive time slots, the modulator may generate a carrier frequency selected by the channel selection input and offset by the first modulation input. The modulator may alternate between providing modulated transmit signals during transmit time slots and providing a local oscillator for the receiver during receive time slots. | 12-17-2009 |
20120026988 | Wireless Communication Sharing in a Common Communication Medium Based on Voice Traffic Prediction - Performing wireless communication using first and second wireless communication protocols. The first and second wireless communication protocols may operate in a common communication medium. The wireless communication may be performed using the protocols over the common communication medium, e.g., in a time sharing fashion. Properties of voice traffic on current frames of the second wireless communication protocol may be measured. The method may further include predicting whether one or more subsequent frames of the second wireless communication protocol will have voice traffic. If the prediction indicates that the one or more subsequent frames of the second wireless communication protocol will not have voice traffic data may be transmitted using the first wireless communication protocol on the common communication medium during a subsequent second wireless communication protocol time slot. | 02-02-2012 |
