| 20100139306 | AIR CYCLE HEAT PUMP TECHNIQUES AND SYSTEM - In one aspect, there is provided a heat pump system which comprises an enclosure and an electrostatic compressor. The enclosure is substantially filled with a first fluid and includes a plurality of compressor vanes, a heat exchanger, and a control module. The plurality of compressor vanes are responsive to electrical stimulus and are substantially separated from each other so that the first fluid extends to and at least partially occupies a space between adjoining pairs of the compressor vanes. The heat exchanger is thermally coupled to the first fluid in the space between the compressor vanes and to a second fluid substantially outside the enclosure. The control module is responsive to input information and includes an electrical circuit that provides the electrical stimulus to the compressor vanes. The compressor vanes respond to the electrical stimulus by compressing and releasing the first fluid between the adjoining pairs of compressor vanes. | 06-10-2010 |

| 20110156178 | Micro-Electro-Mechanical System Having Movable Element Integrated into Leadframe-Based Package - A MEMS may integrate movable MEMS parts, such as mechanical elements, flexible membranes, and sensors, with the low-cost device package, leaving the electronics and signal-processing parts in the integrated circuitry of the semiconductor chip. The package may be a leadframe-based plastic molded body having an opening through the thickness of the body. The movable part may be anchored in the body and extend at least partially across the opening. The chip may be flip-assembled to the leads to span across the foil, and may be separated from the foil by a gap. The leadframe may be a prefabricated piece part, or may be fabricated in a process flow with metal deposition on a sacrificial carrier and patterning of the metal layer. The resulting leadframe may be flat or may have an offset structure useful for stacked package-on-package devices. | 06-30-2011 |

| 20100045569 | Display Systems and Methods for Mobile Devices - Display systems and methods for mobile devices and mobile devices are disclosed. In one embodiment, a display system for a mobile device is provided. The mobile device is handheld and includes a primary display screen. The display system includes an auxiliary screen and a connecting device coupled to the auxiliary screen and attachable to the mobile device. An image from the mobile device is producible on the auxiliary screen. The display system is removable from the mobile device. | 02-25-2010 |
| 20100164716 | SYSTEM AND METHOD FOR MONITORING DISPENSING OF MEDICATION - A system is capable of monitoring dispensing of medication from a medication container having a volume. The system comprises a measuring portion and a processor portion. The measuring portion is operable to measure a parameter at a first time and to measure the parameter at a second time. The processor portion is in communication with the measuring portion. The processor portion is operable to determine a change in volume of medication within the medication container based on the measured parameter at the first time and the measured parameter at the second time. | 07-01-2010 |
