| 20110147005 | METHOD OF RUNNING A DOWN HOLE ROTARY PUMP - A method of running a down hole rotary pump using a top drive, sucker rod or any drive shaft from surface. A first step involves providing a gear box having an input end and an output end. The gear box is being capable of receiving an input of a first speed at the input end and producing an output of a second speed which is one of either faster or slower than of the first speed at the output end. A second step involves positioning the gear box down hole with the input end coupled to a remote lower end of a sucker rod and the output end coupled to a rotary activated pump. A third step involves applying a driving force to the sucker rod to rotate the sucker rod at the first speed, with the rotational force being transmitted to the rotary activated pump through the gear box which rotates the rotary activated pump at the second speed. | 06-23-2011 |

| 20100253768 | APPARATUS AND METHOD FOR GENERATING AND DISPLAYING A STEREOSCOPIC IMAGE ON A MOBILE COMPUTING DEVICE - An apparatus and method for generating and displaying a stereoscopic image on a mobile computing device. The apparatus includes an autostereoscopic overlay which is secured over at least a portion of the screen of the mobile computing device, such as by using a case. Computer-readable instructions are executed on the mobile computing device to align two captured images, if necessary, and interlace them into an interlaced image for subsequent display to the screen of the mobile computing device. When the displayed image is viewed by the user of the mobile computing device through the autostereoscopic overlay, the image appears as a stereoscopic (or three-dimensional) image. | 10-07-2010 |

| 20090058431 | ETCH RESISTANT GAS SENSOR - A gas sensor for sensing noxious chemical gases utilizes metal nitrides, metal oxynitrides, metal carbides or metal oxycarbides as the sensing material, which changes its conductivity when exposed to the analyte gas. The change in conductivity is measured for the sensor output. | 03-05-2009 |
| 20090090170 | ETCH RESISTANT GAS SENSOR - A gas sensor for sensing chemical gases utilizes a metal oxynitride as the sensing material, which changes its conductivity when exposed to the analyte gas. The change in conductivity is measured for the sensor output. The metal may be either tungsten or molybdenum. | 04-09-2009 |
| 20100089122 | GAS SENSOR - A sensor system issues measurement commands at a predetermined regular rate. If a measurement indicates that a gas of interest is present, then the sensor system is signaled to wake-up thereby pulsing a heater for the sensor element that improves the accuracy of measurements. Measurements of humidity, temperature and gas concentration are made. If the gas of interest is detected then the data is used to indicate a compensated gas measurement. The gas level is classified as to its hazard and an adaptive detection algorithm is used to set an activity mode. If the gas of interest is not detected, the adaptive detection algorithm is used to set a sleep mode that saves power. Measurement rates are kept constant while heater power is controlled to reduce power consumption. Measurement rates are changed to increase concentration sensitivity. | 04-15-2010 |

| 20120026986 | Downlink frequency selective scheduling based on channel quality feedback - A method for downlink frequency selective scheduling in LTE MAC based on channel quality feedback is disclosed. Existing methods for resource allocation have no means for efficient utilization of the resources and allocation of the available downlink bandwidth to the UE with low computation overhead. These methods do not ensure that the UEs that possess channel quality feedbacks are allocated their best sub-bands for transmission in time and compute efficient manner. The proposed method employs CQI based feedback from the UEs for allocation of the downlink bandwidth. The method defines a threshold value for the CQI and UEs that have sub-bands with CQI lesser than the defined threshold value will not be allocated resources in the corresponding sub-band. | 02-02-2012 |
