| Number | Title | Issue Date |
| 8149169 | Extensible object location system and method using multiple references An ultra wideband (UWB) or short-pulse RF system is disclosed that can be used to precisely locate or track objects (such as personnel, equipment, assets, etc.) in real-time in an arbitrarily large, physically connected or disconnected, multipath and/or noisy enviro... | 04/03/2012 |
| 8063826 | Wireless time reference system and method Instead of normalizing time reference of independent spatially-located clocks using a reference tag transmission from known location, the present invention uses an interarrival time interval between a pulse pair of UWB pulses as a timing metric. Thus, a method of sy... | 11/22/2011 |

Thus, a method of sy... | 02/17/2009 |
| 7412007 | High efficiency ultra wideband generator A method and system to produce a spectrally filtered ultra wideband (UWB) signal preferably utilizing a singly terminated filter having an input section and a current switching device directly coupled to the input section. The switching device is operated in a highl... | 08/12/2008 |
| 7369598 | Ultra-wideband receiver and transmitter A waveform-adaptive ultra-wideband (UWB) transmitter and noise-tracking UWB receiver for use in communications, object detection and radar applications. In one embodiment, the output of an oscillator is gated by a low-level impulse generator either directly or throu... | 05/06/2008 |
| 7209523 | Ultra-wideband receiver and transmitter A waveform-adaptive ultra-wideband (UWB) transmitter and noise-tracking UWB receiver for use in communications, object detection and radar applications. In one embodiment, the output of an oscillator is gated by a low-level impulse generator either directly or throu... | 04/24/2007 |
| 6882315 | Object location system and method An RF object locating system and method that uses or includes a set of N (N>2) receivers (monitoring stations) located at fixed positions in and/or about a region to be monitored, one or more reference transmitters that transmit a timing reference, a location proces... | 04/19/2005 |
| 6812884 | Transceiver system and method utilizing nanosecond pulses A transceiver for short-pulse radar applications is disclosed in which a shift register or the like is used to collect return signal information in a manner to reduce the number of transmit pulses needed and to increase the speed of determining the positions of mult... | 11/02/2004 |
| 6690741 | Ultra wideband data transmission system and method A data-modulated ultra wideband transmitter that modulates the phase, frequency, bandwidth, amplitude and/or attenuation of ultra-wideband (UWB) pulses. The transmitter confines or band-limits UWB signals within spectral limits for use in communication, p... | 02/10/2004 |
| 6586999 | Ultra wideband transmitter with gated push-pull RF amplifier A method and an apparatus that reduce power consumption in an ultra wideband (UWB) transmitter that includes a push-pull RF amplifier and a switch that powers up or powers down the amplifier between UWB pulses. The gated push-pull amplifier amplifies the ... | 07/01/2003 |
