Equalizer training is validated by techniques to detect false training. The validation techniques involve checking the unique time domain energy shaping of a plurality of taps of a trained equalizer of a modem for good training. The energy measure for each equalizer tap of the plurality of taps is approximated by summing the magnitude of a real component and a magnitude of an imaginary component of an equalizer coefficient corresponding to the equalizer tap. A tap with a highest approximate energy (i. e. , the main tap) is then determined. Next, the main tap energy is compared to a main tap threshold and a predetermined guarding threshold. The plurality of taps are arranged in a time index ordered sequence. In determining the main tap threshold, a first energy sum of a beginning set of taps in the sequence is compared with a second energy sum of a last set of taps in the sequence. The lesser tap energy sum between the first energy sum and the second energy sum is the main tap threshold.

A system for providing vision contains an aberrometer, a wavefront sensor, and a transfer optical system. The aberrometer is configured to measure a received wavefront. The aberrometer includes a wavefront sensor and a transfer optical system for transferring an input wavefront so as to the provide the received wavefront at or near the wavefront sensor. The system also includes a processor in communication with the aberrometer, a readable memory, and instructions located within the memory. The readable memory contains one or more system error parameters and instructions available to the processor. The instructions are for determining at least one aberration of the received wavefront and calculating the input wavefront based on the received wavefront and the one or more system error parameters.

A single control roman tub faucet () comprises a handle, a lever coupled to the handle, and a cartridge valve () coupled to the lever. The valve () is configured to provide a maximum flow rate of at least 7.8 GPM. The cartridge valve () has a valve base () and a lower disk (). The valve base () includes an upper surface () and a lower surface () and a water passage extending between the upper and lower surfaces. The outlet end of the passage has a larger cross-sectional area than the inlet end. The lower disk () includes an inlet sized to match the outlet end of the passage. The cross section of the passage is generally arcuate and is defined by parallel side walls () and non-parallel end walls ().
