Abstract: A uniplanar dual strip antenna that has a two dimensional structure. The antenna is comprised of a first and a second metallic strip, each printed or etched on a thin planar substrate. The first and second strips are separated by a predetermined gap and are used as conductors of a two-wire transmission line. A coplanar waveguide is coupled to the uniplanar dual strip antenna. The coplanar waveguide is constructed by printing or etching metal on the substrate. The positive terminal of the waveguide is electrically connected to the first strip. The negative terminal of the waveguide is electrically connected to both the first and second strips. The uniplanar dual strip antenna according to the present invention provides an increase in bandwidth over typical quarter wavelength or half wavelength patch antennas. Experimental results have shown that the uniplanar dual strip antenna has a bandwidth of approximately 8-20% that is extremely desirable for PCS and cellular phones.

Abstract: In a remote unit receiver capable of demodulating a plurality of signal instances corresponding to a singe remote unit transmitted signal, a first instance of a signal is demodulated to produce a first set of energy values corresponding to a set of possible data values of the signal. A second instance of the signal is demodulated to produce a second set of energy values corresponding to the set of possible data values. The first and the second sets of energy values are then combined to determine a combined set of energy values. A first estimate of a most likely transmitted data value is determined based upon the combined set of energy values An energy level of the first instance is determined based upon the energy value within the first set of energy values corresponding to the first estimate of the most likely transmitted data value.

Abstract: The present invention is a novel and improved AGC circuit which is generically configurable to accommodate a variety of AGC amplifier configurations to enhance IP3 performance and reduce required amplifier current, while providing a received power estimate which remains valid regardless of how the gain or attenuation is distributed among the various amplifiers. A generic control circuit maintains this power estimate in a single overall gain amplification value by distributing gain to at least two amplifier stages in response to that value. By programming or hard coding a few key parameters, a generic control circuit can control a wide variety of amplifier configurations. Among the configurations supported are switched LNA, switched variable gain LNA, variable gain, and a decoupled IF and UHF variable gain LNA configuration. The invention is extendable to include multi-stage amplifier configurations.

Abstract: A damped double flywheel comprises two coaxial inertia masses which are mounted for relative rotation, both against the action of a first series of springs and against the action of a viscous damping means. A damper wheel connects the viscous damping means with the first series of springs, and the latter couple the damper wheel with a first damping control means carried by the first mass. A second series of circumferentially acting springs, of greater stiffness than the first series of springs, couples the damper wheel to a second damping control means which is carried in rotation on the second mass.

The first annular component is mounted to define a dead clearance in which there is no operation of the resilient spring and an abutment defines the range of annular displacement of the dead clearance.

Abstract: A leno or cross weaving texture is produced with a stationary warp thread and a cross warp thread which is alternately shifted from one side to the other of the stationary warp thread. The method of producing the leno weave includes the steps of providing a line segment of the stationary warp thread which connects first and second planes provided on the respective sides of the stationary warp thread, inclining the line segment of the stationary warp thread so as to cross a weaving plane alternately from an upper side of the first plane to an under side of the second plane, and from an under side of the first plane to an upper side of the second plane, and moving the cross warp thread in a perpendicular direction relative to the weaving plane and above the inclined line segment so that the cross warp thread is caused, during its movement, to slide along the inclined line segment towards the first plane or the second, thus producing the leno weave.
