20100184009 | TEACHING AND ASSESSMENT METHODS AND SYSTEMS - The invention relates to methods and systems for teaching and assessing a set of targets to a student, particularly in the field of literacy. One application of the invention is in teaching sound-symbol relationships. The invention using a rapid learning system, whereby each target is associated with a completion score and a student score. A student is prompted to identify a particular target (from a number of options). When the student correctly identifies a target, the student score is incremented until it reaches a completion score. The student score is decremented for incorrect responses. A support mechanism (e.g. a mnemonic) may be provided to the student—as a student shows increased proficiency, the level of support is reduced. This may be done by “morphing” the mnemonic into a standard representation of the target. Associated methods and systems are also disclosed. | 07-22-2010 |

20130260703 | ULTRA-WIDEBAND HIGH POWER AMPLIFIER ARCHITECTURE - Techniques and architecture are disclosed for providing an ultra-wideband, multi-channel solid-state power amplifier architecture. In some embodiments, the architecture includes a power divider which splits an input signal and delivers that split signal to a plurality of downstream channel chipsets. Each channel chipset is configured to amplify a sub-band of the original full-band input signal and to provide the resultant amplified sub-band for downstream use, such as for transmission by an antenna operatively coupled with that channel. In the aggregate, the amplified sub-bands provide coverage of the same ultra-wideband frequency range of the original input signal, in some cases. In some embodiments, the architecture provides high radio frequency (RF) power with good amplifying efficiency and ultra-wide instantaneous frequency bandwidth performance in a small-form-factor package. In some instances, control circuitry is provided to control which chipset die(s) are enabled/disabled, thus providing control over gain and power levels of the output signal(s). | 10-03-2013 |
