Title: Method for evaluating the power output of a drilling motor under downhole conditions
Inventor: PAFITIS DEMOSTHENIS
IPC: E21B44/00
Filed: 1998-05-04
Abstract: A procedure is described for determining the power output of a downhole drilling motor, when the motor is inside the wellbore. The technique uses stand-pipe pressure and fluid flow rate as the main inputs. The power output of the motor is calculated by carrying out two low flow stall tests at flow rates lower than the drilling flow rate. These tests result in "off bottom" and stall pressures at the two flow rates. Another off bottom pressure is taken at the actual flow rate that will be used during drilling operations. From the use of the off bottom and stall pressure measurements, a determination is made of the differential pressure across the motor and the stall pressure at the actual drilling fluid flow rate. A full power curve and a predicted operating stand-pipe pressure for optimal power generation are provided based on an experimentally verified assumption regarding the change in rotation rate of the motor versus the differential pressure across the motor power section.

Title: Dual-mode radio receiver for receiving narrowband and wideband signals
Inventor: DENT PAUL W
IPC: H04B7/185
Filed: 1996-03-01
Abstract: A radio receiver for a radio operable in a radio communication system utilizing either a wideband standard such as GSM or a narrowband standard such as IS-54. The radio receiver has a wideband mode for demodulating wideband signals and a narrowband mode for demodulating narrowband signals. The radio receiver uses a wideband filter apparatus having a wide filter bandwidth adapted to the wideband signals for filtering both the wideband and narrowbans signals. When in the narrowband mode, a digitizer digitizes the filtered signals containing the narrowband signal and produces digital signals having amplitude and phase signals corresponding to the filtered signals. A digital signal processor is used to frequency-shift the digital signals so as to shift the narrowband signals to the center frequency of the wideband filter apparatus. The frequency-shifted narrowband signals are then filtered to select the centered narrowband signals and the narrowband signals are then demodulated. The digital signal processor is adapted to frequency-shift a plurality of different narrowband signals at different radio channel frequencies and to demodulate the different narrowband signals to provide for diversity combinaison.
