Did You Know...
...that in the early 1940s GE engineer James Wright was charged with a task of utmost importance to the war effort: develop a cheap substitute for rubber that could be used to produce tires, gas masks and a whole host of military gear. Wright tackled the task diligently -- and wound up inventing Silly Putty.

| Number | Title | Issue Date |
| 7873127 | Weighting a signal received by an antenna array to enhance the signal and suppress interference Sample vectors of a signal received simultaneously by an array of antennas are processed to estimate a weight for each sample vector that maximizes the energy of the individual sample vector that resulted from propagation of the signal from a known source and/or min... | 01/18/2011 |
| 7856050 | Receiver and transmitter calibration to compensate for frequency dependent I/Q imbalance A receiver, which is adapted for demodulating signal carriers at variable frequencies to provide received signals at a plurality of different received frequencies, is calibrated to compensate for a frequency-dependent imbalance in the amplitude and/or the quadrature... | 12/21/2010 |
| 7844017 | Carrier frequency detection for signal acquisition A carrier frequency in a filtered received M-ary phase-shift keyed (MPSK) modulated signal having in-phase and quadrature components is detected by processing the filtered received signal to remove modulation components and thereby generate a test signal at the carr... | 11/30/2010 |
| 7835719 | Detection of signals in a radio network In a radio network that includes at least one base station and at least one remote station, signals are modulated for transmission from the remote stations by embedding known information throughout the signal in a predetermined pattern and a group of sample vectors ... | 11/16/2010 |
| 7643535 | Compatible preparation and detection of preambles of direct sequence spread spectrum (DSSS) and narrow band signals The preambles of narrow band signals and DSSS signals are prepared for compatible detection. The preamble is encoded by encoding a sequence of identical preamble blocks with sequentially corresponding code elements of a preamble encoding sequence. Each of the identi... | 01/05/2010 |
| 7606342 | Tracking the phase of a received signal The tracking of the phase of a received signal having a known preamble is accomplished by the steps of: initializing a phase-locked loop in accordance with estimated phase parameters, which are generated during an estimation interval by processing samples of the kno... | 10/20/2009 |
| 7528396 | Solid state simulator of missile UV signatures Apparatus for simulating ultraviolet (UV) signatures of missiles includes a memory, control electronics, drive electronics and at least one solid-state UV-radiation emitter. Waveform data that is characteristic of the UV-signatures of different types of missiles is ... | 05/05/2009 |
| 7477192 | Direction finding system and method In a direction finding system, pluralities of signals provided by different sets of less than all of a plurality of arrayed antennas are code division multiplexed, downconverted by a single receiver, A/D converted and separated to derive signals that are processed t... | 01/13/2009 |
| 7456521 | Electronically reconfigurable battery An electronically reconfigurable battery includes a number of battery modules selectively interconnected by a number of electronic switches, wherein a selectable number of battery modules may be connected either in a series configuration or in a parallel configurati... | 11/25/2008 |
| 7436370 | Device and method for polarization control for a phased array antenna A method of configuring a phased array antenna having a plurality of radiators, each said radiator elements capable of radiating or receiving signals in one of two orthogonal polarizations determined to achieve a pseudo-random mix of horizontally and vertically pola... | 10/14/2008 |
| 7397871 | Estimation of single-to-noise ratio by processing measured error vector magnitude The signal-to-noise ratio of a demodulated received signal is estimated by measuring the error vector magnitude (EVM) of the demodulated signal; and processing the measured EVM in combination with a correction term to estimate the signal-to-noise ratio of the demodu... | 07/08/2008 |
| 7336732 | Carrier frequency detection for signal acquisition A carrier frequency in a filtered received M-ary phase-shift keyed (MPSK) modulated signal having in-phase and quadrature components is detected by processing the filtered received signal to remove modulation components and thereby generate a test signal at the carr... | 02/26/2008 |
| 7315565 | System for, and method of, providing frequency hopping In many systems now in use for sending digital data from a controlled station (e.g., a transmitting station), generally indicated at 10 in FIG. 1, to a controlling station (e.g., a receiving station) generally indicated at 12, a plurality of hopping frequenci... | 01/01/2008 |
