Title: Chemoprotectants from crucifer seeds and sprouts
Inventor: MATUSHESKI NATHAN
IPC: A23L19/00
Filed: 2006-08-01
Abstract: The present invention is directed to chemoprotectant precursor compositions provided from crucifer seeds and sprouts and methods for their preparation. Treatment of aqueous extracts from crucifer seeds or sprouts with adsorbents substantially increases the ratio of certain highly chemoprotectant precursor compounds (alkyl glucosinolates such as glucoraphanin, a.k.a. sulforaphane glucosinolate) to undesirable compounds such as indole glucosinolates (for example 4-hydroxyglucobrassicin). The method provides an extract which has a ratio of glucoraphanin to 4-hydroxyglucobrassicin of about 70 or greater. The resulting extract has improved color and odor and may be dried or used directly as an additive in a variety of foodstuffs.

Title: Digital predistortion system and method for high efficiency transmitters
Inventor: COVA ARMANDO
IPC: H04L1/00
Filed: 2005-02-23
Abstract: A system for digitally linearizing the nonlinear behaviour of RF high efficiency amplifiers employing baseband predistortion techniques is disclosed. The system provides additive or multiplicative predistortion of the digital quadrature (I/Q) input signal in order to minimize distortion at the output of the amplifier (100, 200). The predistorter (108, 202) uses a discrete-time polynomial kernel to model the inverse transfer characteristic of the amplifier (100, 200), providing separate and simultaneous compensation for nonlinear static distortion, linear dynamic distortion and nonlinear dynamic effects including reactive electrical memory effects. Compensation for higher order reactive and thermal memory effects is embedded in the nonlinear dynamic compensation operation of the predistorter in an IIR filter bank (334). A predistortion controller (420, 520) periodically monitors the output of the amplifier (100, 200) and compares it to the quadrature input signal to compute estimates of the residual output distortion of the amplifier. Output distortion estimates are used to adaptively compute the values of the parameters of the predistorter (108, 202) in response to changes in the amplifier's operating conditions (temperature drifts, changes in modulation input bandwidth, variations in drive level, aging, etc). The predistortion parameter values computed by the predistortion controller are stored in non-volatile memory and used in the polynomial digital predistorter. The digital predistortion system of the invention may provide broadband linearization of highly nonlinear and highly efficient RF amplification circuits including, but not limited to, dynamic load modulation amplifiers.
