| 20100058569 | SYSTEM FOR DISASSEMBLING TRANSMISSION VALVE BODY ASSEMBLY - An improved system and method for disassembling the valve body assembly of a motor vehicle transmission. Air automatically ejects the internal components of a valve body assembly sub-assembly, thereby eliminating the need for an operator to manually “beat” the sub-assembly to remove said internal components. The process of separating the upper and lower sub-assembly, and of pre-washing the sub-assembly, remain the same as in the prior art. As before, the operator manually removes the valve retainers and plugs in each sub-assembly. The operator then loads either sub-assembly onto tooling specifically designed for that sub-assembly (either upper or lower). Once started, the tooling begins an automated, pre-programmed sequence of (1) clamping the sub-assembly, (2) injecting air into specific valve ports to eject internal components causing them to be automatically ejected into parts bins specified for each valve port, and (3) releasing the sub-assembly that no longer contains any internal parts. | 03-11-2010 |

| 20100252176 | METHOD FOR FORMING GATE STRUCTURES - A process for forming gate structures is described. A web comprises a substrate, a plurality of conductive elements disposed on the substrate, and a conductive anodization bus. The web is moved through an anodization station to form a plurality of gate structures comprising a plurality of gate dielectrics adjacent to a plurality of gate electrodes. A process for forming electronic devices further providing a semiconductor, a source electrode, and a drain electrode is described. | 10-07-2010 |
| 20110117750 | NOVEL WET ETCHING AGENT FOR II-VI SEMICONDUCTORS AND METHOD - A novel etching agent for etching II-VI semiconductors is provided. The etching agent includes an aqueous solution of potassium permanganate and phosphoric acid. This etching solution can etch II-VI semiconductors at a rapid rate but tend to be much less reactive with III-V semiconductors. The provided agent can be used in a method for etching II-VI semiconductors. | 05-19-2011 |

| 20090201023 | Pre-Amplifier and Mixer Circuitry for a Locator Antenna - A pre-amplifier circuit for connection to an antenna of a human-portable locator includes a differential amplifier/mixer pair and means for allowing a common-mode “phantom” signal to modulate a transfer function of the differential amplifier/mixer pair. The common-mode phantom signal modulates the transfer function of the differential pre-amplifier “onboard” the antenna without the usual requirement for onboard power supply and signal oscillator. This technique uses the same electronic components to provide both pre-amplification and mixing functions, thereby improving circuit performance-to-cost ratio, reducing mixer power consumption, situating the necessary signal oscillator remotely from the mixer, and greatly improving the available system bandwidth by limiting spectral transmission demands to the mixed signal bandwidth alone. | 08-13-2009 |
| 20100225752 | Method and apparatus for high-speed data transfer employing self-synchronizing quadrature amplitude modulation - A Quadrature Amplitude Modulation (QAM) method and apparatus including a QAM transmit modulator with at least one unbalanced mixer, which creates an asymmetric two-dimensional (2-D) QAM symbol constellation. The asymmetrical symbol constellation provides baseband symbol clock signal leakage sufficient to facilitate quick and simple baseband symbol clock recovery and signal channel compensation at the QAM receiver without significantly degrading the system bit-error rate (BER). While slightly degrading static BER, overall system performance is improved when considering baseband symbol clock recovery and received signal compensation for an imperfect signal channel. This allows QAM to be deployed in systems where QAM is otherwise prohibitively expensive and improves overall system performance for any existing QAM system application without additional bandwidth, cost or complexity. | 09-09-2010 |
