Title: Method and system enabling use of white space radio spectrum using digital broadcast signals
Inventor: SINGH RAJENDRA
IPC: H04W4/20
Filed: 2009-06-11
Abstract: A system (10) and method (50 or 70) of dynamic allocation of spectrum for a communication device where a UHF band is currently unused for licensed television broadcasting involves determining (51) a location of a user device using GPS or other signals (such as television broadcast signals) received at the user device using signal strength or time distance of arrival of those signals. The method can determine (52) which UHF television broadcast channels are available for use by the user device and determine (53) a maximum allowed transmission power for a given channel based on signal strength for the given channel and on adjacent channels before transmitting (54) the maximum allowed transmission power and location by the user device to a remote server for sharing information. The method can receive (55) polygon endpoints from a television broadcast defining the location of usable reception of the television broadcast.

Title: Sand check filter
Inventor: FORD MICHAEL BRENT
IPC: E21B37/08
Filed: 2012-02-23
Abstract: A sand check filter for preventing solids from reentering into a pump. The filter is designed to mount atop a conventional rod pump. The filter allows well fluid, that contains high solids, to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The filter includes a sleeve that has radial flutes that allows the sleeve from hanging up, sticking to or wedging itself to the valve rod. The sleeve is rotated on the valve rod to create a valve effect atop the filter. This prevents the fluid from passing through the inner diameter of the screen and forces solids within the fluid to be redirected to the outer diameter of the filter. This allows the fluid to be filtered before reentering the pump.
