A face feature analysis which begins by generating multiple face feature candidates, e.g., eyes and nose positions, using an isolated frame face analysis. Then, a nostril tracking window is defined around a nose candidate and tests are applied to the pixels therein based on percentages of skin color area pixels and nostril area pixels to determine whether the nose candidate represents an actual nose. Once actual nostrils are identified, size, separation and contiguity of the actual nostrils is determined by projecting the nostril pixels within the nostril tracking window. A mouth window is defined around the mouth region and mouth detail analysis is then applied to the pixels within the mouth window to identify inner mouth and teeth pixels and therefrom generate an inner mouth contour. The nostril position and inner mouth contour are used to generate a synthetic model head. A direct comparison is made between the inner mouth contour generated and that of a synthetic model head and the synthetic model head is adjusted accordingly. Vector quantization algorithms may be used to develop a codebook of face model parameters to improve processing efficiency. The face feature analysis is suitable regardless of noise, illumination variations, head tilt, scale variations and nostril shape.

In the thin-film magnetic head of the present invention, the distance to a heat-generating layer is shorter from the end part on the side facing, a recording medium in a magnetoresistive device than from the end part on the side facing the recording medium in an electromagnetic transducer. Therefore, even when the thin-film magnetic head tilts so that its electromagnetic transducer side approaches the recording medium when floating up from the recording medium, the amount of thermal expansion caused by the heat from the heat-generating layer is greater in the magnetoresistive device than in the electromagnetic transducer. This reduces the gap between the magnetoresistive device and the recording medium, whereby a high reproducing output can be obtained.

A self-contained head set based sleep or fatigue alarm for a driver of a vehicle contains a set of arms extending from the alarm housing around the driver's head to the area under the driver's lower jaw. Involuntary relaxation of the driver's lower jaw causes rotation of the arms which in turn urges the movable contact against the stationary contact and therefore leads to the completion of the electrical circuit. After a predetermined delay, a buzzer or vibrator is activated to awaken the driver. In another embodiment, two relaxation motions, jaw lowering and head tilting, are used at the same time to trigger the alarm. In a third embodiment, either one of these two relaxation motions is used to trigger the alarm independently thus increasing the sensitivity of the alarm.

Tilt between a head stack and its associated disk stack in a hard disk drive (HDD) is measured by determining the deviation of a target head from its expected position (based on the position of the current head) each time electrical contact is switched from the current head to a target head. A running average tilt value is stored and used to modify the logical seek distance used in a Rotational Position Optimization (RPO) algorithm to better order I/O requests in a queue. Also, the running average tilt value can be used by the servo to pre-position the target head before electrical contact is made with the target head, to improve speed of operation.
