摘要:
An optical switch having two spherical or elliptical corner-reflecting surfaces provided in a light-conducting member, a shutter to open and close a light path between the corner-reflecting surfaces, and focusing lenses to focus the incident beam from an emitting optical fiber and to focus the emitting beam from the light-conducting member to a primary receiving optical fiber. Because almost all the beam transmitted through the light-conducting member is focused at one point in an air gap in which the shutter moves, the optical switch can transmit the beam with high efficiency without leakage to the outside, and a small stroke of the shutter is sufficient to completely transmit or stop the beam. In another similar optical switch having a reflecting surface at the tip of the shutter for inclining the beam, as well as having a secondary receiving optical fiber aligned with the path of the inclined beam, the beam is switched to be transmitted to the primary receiving optical fiber or to the secondary receiving optical fiber according to the position of the shutter. Thus, the ON/OFF state of the optical switch can be indicated, or a transfer-type optical switch can be obtained by using the secondary receiving optical fiber as well as the primary receiving optical fiber as switching circuits.

An apparatus for determining an occupant's posture is provided which includes a sensor having at least one pair of linear photosensor arrays each comprising a plurality of photosensor elements, for forming an image of an occupant, a distance measurement processor that derives distance distributions in fields of view monitored by the linear photosensor arrays, from the image of the occupant formed by the sensor, and an occupant discrimination processor that compares patterns of the distance distributions with model patterns of distance distributions preliminarily stored in the processor, so as to determine the presence and posture of the occupant. The linear fields of view are set to extend in a substantially horizontal direction with respect to the occupant, and the occupant discrimination processor first examines at least one of symmetry of the distance distribution pattern in each field of view, concave or convex shape of the pattern, degree of similarity in variations in the distance distribution patterns between adjacent fields of view, and a distribution of distances measured at a particular position of the fields of view, and then determines the posture of the occupant by comparing the patterns of the distance distributions actually measured, with a group of model patterns that is selected in advance depending upon the result of the examination.
摘要:
The present invention detects not only the presence of an occupant, but also his/her posture based on the distance distribution of each portion of the occupant within each of monitor fields of view, which distance distribution is obtained by means of a single-stage or multistage occupant sensor. The result of the detection can be used in controlling inflation of an air bag, so as to avoid an accident that might otherwise occur upon inflation of the air bag, thus assuring increased safety and reliability. Since the acceleration can be calculated by arithmetic processing of the output of the distance sensor, there is no particular need to provide an exclusive acceleration sensor. Further, an optical system including the distance sensor may be designed so that the sensor can also detect an occupant whose part of the body is thrust out of automobile.

An electric motor control apparatus includes a phase correction portion that generates and outputs an amount of phase correction with which to correct a phase of a signal from a position sensor detecting a position of a magnetic pole of an electric motor. The phase correction portion generates and outputs an energization stop signal in a case where a rotation speed of the electric motor is within a predetermined range and stores an amount of phase correction generated therein according to a comparison between a signal from the position sensor or a first phase and an induced voltage of the electric motor to output the amount of phase correction.

The present invention provides a plate member conveying apparatus configured such that an occupied area is small, and a plate member is unlikely to be damaged. A plate member conveying apparatus according to the present invention includes a feed device having a conveying portion and a pressurizing portion. The conveying portion includes a belt configured to contact one of surfaces of a plate member in a vertical state to feed the plate member in a conveying direction. The pressurizing portion applies pressure of a fluid to the other surface of the plate member in the vertical state in a direction perpendicular to the surface of the plate member to press the plate member toward the belt. Then, the plate member in the vertical state is conveyed while being held by sandwiching the plate member between the belt of the conveying portion and the fluid of the pressurizing portion.
