A computer-controlled system determines attributes of a frexel, an area of human skin, and applies an electrostatically charged modifying agent (RMA) at the pixel level, to make the skin appear more attractive. The system scans the frexel, identifies unattractive attributes, charges the RMA with an electrostatic charger, and applies the RMA, typically with an inkjet printer. The identified attributes relate to reflectance and may refer to features such as irregular-looking light and dark spots, age-spots, scars, and bruises. Identified attributes may also relate to the surface topology of the skin, for more precisely enhancing surface irregularities. Feature mapping may be used, for example to make cheeks appear pinker and cheekbones more prominent. The charged RMA can be applied in agreement with identified patterns, such as adding red to a red frexel, or in opposition, such as adding green or blue to a red frexel, according to idealized models of attractiveness.

The present invention is a system for and method of adjusting hearing aids (130) by discrete frequency ranges (FIG. 3a); continual tuning and reprogramming of the hearing aid is accomplished in real time via iterations between a patient (with hearing aid in ear, 120) and an audiologist (131). A test tone or other sound is played and the patient gives feedback on the test tone's suitability (such as loudness). The hearing aid (130) is further tuned and reprogrammed accordingly as the sound is replayed and the patient (120) gives additional feedback. These steps continue until the patient (120) considers the hearing optimized, compensating for both the patient's hearing loss and individual preferences in the discrete frequency ranges. The following are twelve commonly tested frequency ranges: 125 Hz, 250 Hz, 750 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 3000 Hz, 4000 Hz, 5000 Hz, 6000 Hz, 8000 Hz, and 10,000 Hz.

A method and apparatus for customizing an intervertebral implant includes the initial step of obtaining a 3D anatomy of a series of vertebrae including an abnormal vertebra in a computer. The 3D anatomy of the series is then repositioned in the computer to eliminate the deformity caused by the abnormal vertebra. It is next determined whether a superior or inferior surface of the abnormal vertebra is an abnormal surface which causes the deformity, whereby an approximate gap between the abnormal surface and a desired normal surface is determined. Using that gap determination, a custom implant is constructed to engage the abnormal surface and fill the determined gap. Thus, when the implant is implanted between the abnormal surface and an adjacent surface of an adjacent vertebrae, the deformity is substantially compensated for. The implant may have articulation between the endplates to allow relative movement therebetween.
