Approche hybride de classification supervisée à base de treillis de Galois : application à la reconnaissance de visages

A motorized infant rocking device is disclosed which will rock an infant resting in an infant seat or crib in a soothing manner for a predetermined period of time. In a first embodiment, the apparatus includes a track mounted to a stationary base and a glide mechanism mounted to a support beam which slidably engages the track. A rotary motor is mounted to the support beam and includes an eccentric which operatively engages a drive surface mounted to the stationary base, to impart oscillating linear motion to the support beam. An infant holding device such as an infant seat or crib is mounted to the support beam and undergoes linear oscillatory motion with respect to the base in response to the operation of the motor. In a second embodiment, rollers are mounted to a stationary base and glide rails rollably engage the rollers. A rotary motor is mounted to the base and has an eccentric which is operatively connected to the glide rails, to impart oscillating linear motion to the glide rails along the rollers. An infant holding device such as an infant seat or crib is mounted to the glide rails and undergoes linear oscillating motion with respect to the base in response to the operation of the motor. The resulting smooth oscillatory motion has a soothing effect on an infant seated in the holding device.
