Yadunandana N Rao, Chet A Lampert: Method for correcting imbalance errors in a direct conversion receiver. Motorola Solutions, Barbara R Doutre, December 17, 2013: US08611479

A communication system comprises a direct conversion receiver for correcting imbalance errors. The direct conversion receiver receives a radio frequency (RF) signal and converts the RF signal to baseband signals. The direct conversion receiver further translates the baseband signals to digital signa ...

Charles B Swope, Chet A Lampert: Device for use with a portable inertial navigation system ("PINS") and method for transitioning between location technologies. Motorola, September 25, 2003: US20030182053-A1

A perimeter threshold of an area is defined. The location of a device (102) is tracked using a first location technology (108) when the device (102) precedes the perimeter threshold. The location of the device (102) is tracked using a second location technology (100) when the device (102) exceeds th ...

Charles B Swope, Chet A Lampert: Method for reducing position uncertainty of a portable inertial navigation device. Motorola, January 1, 2004: US20040002828-A1

A first set of coordinates (100) of a device and an estimated positional error (“EPE”) radius (102) is measured. An EPE circle (104) is derived, in which the device is approximately located, from the first set of coordinates (100) and the EPE radius (102). When it is determined that the EPE radius ( ...
