A nut leadscrew type automatic door opening and closing mechanism, an automobile automatic door, and an automobile. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a gearbox, a nut gear, and a leadscrew. The driving device is fixedly connected to a door, the gearbox is hinged to the door, and the nut gear is disposed in the gearbox. One end of the leadscrew is hinged to a vehicle body, and the other end extends in an axial direction. The nut gear is sleeved on the leadscrew, and the driving device is configured to drive the nut gear to rotate, so that the nut gear is reciprocally linearly movable along the leadscrew to push the door to open or close relative to the vehicle body.

A nut leadscrew type automatic door opening and closing mechanism for moving a door of a motor vehicle relative to a vehicle body. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a leadscrew, a nut pushing block and a pushing rod. The driving device is fixedly connected to a door, the leadscrew is rotatably mounted on the door, the nut pushing block is sleeved on the leadscrew, a first end of the pushing rod is hinged to the nut pushing block, and a second end of the pushing rod is hinged to the vehicle body. The driving device is capable of driving the leadscrew to rotate, so as to allow the nut pushing block and the pushing rod to be reciprocally linearly movable along the leadscrew to allow the pushing rod to drive the door to open or close relative to the vehicle body.

A vehicle control device includes image capturing units, control equipment that extracts at least one living body from image information captured by the image capturing units and performs processing, and a door operating system capable of unlocking the doors of a vehicle and executing an opening operation for the doors. When a user of the vehicle is included among a plurality of the extracted living bodies and it is estimated that a predetermined type of living body is in contact with the user, the control equipment causes the doors to be operated in a first mode. When the user is included among the plurality of the extracted living bodies and it is estimated that the predetermined type of living body is not in contact with the user, the control equipment causes the doors to be operated in a second mode that differs from the first mode.

In a conventional fine particle detection device that vaporizes fine particles attached to the object of examination by heating, processing capability decreases as the processing time elapses due to the influence of deposition of fine particles other than the object of examination, dirt/dust, a residue of the fine particles as the object of examination, or residual matter. A fine particle detection device according to the present invention includes: a vaporization device that vaporizes the fine particles trapped by a trap device by vaporization or decomposition; a first flow passageway in which a mixture of a component vaporized by the vaporization device and another component flows; a second flow passageway branching from the first flow passageway in a direction of inertial force acting on the other component; a third flow passageway branching from the first flow passageway in a direction different from the direction of the inertial force; and an analysis device that analyzes a component introduced into the third flow passageway.

A method for operating a vehicle includes: ascertaining a danger measure of a possible stop position for a safe parking of the vehicle; comparing the ascertained danger measure to a predetermined danger measure threshold value; and guiding the vehicle to the possible stop position in order to safely park the vehicle in the possible stop position only if the ascertained danger measure is less than or equal to the predetermined danger measure threshold value.

A gray code driving device for an electric roller shutter contains: a base, a transmission assembly, and a torque detection unit. The base includes an accommodating space for accommodating the transmission assembly and the torque detection unit and includes a rotary cover connected with the transmission assembly. The transmission assembly includes an electric motor for supplying power source, and the base further includes a digital module for controlling the electric motor. The torque detection unit is in connection with the transmission assembly and is driven by the transmission unit to encode gray codes, wherein the torque detection unit is electrically connected with the digital module to transmit the gray codes.

Aspects of the disclosure relate to deploying safety mechanisms in an autonomous vehicle. As an example, the situational information identifying a potential impact target corresponding to an object with which the autonomous vehicle is predicted to have a collision within a predetermined period of time may be received. This situational information may also include an estimated time when the second computing device will receive an update for the potential impact target from the first computing device. The estimated time may be used to determine when to deploy a set of active safety mechanisms for the potential impact target. Each active safety mechanism may be configured to reduce a likelihood of damage to an object external to the autonomous vehicle caused by a collision. A signal is then sent to activate the set of active safety mechanisms prior to an impact with the object corresponding to the identified potential impact target.

A shaft-mounted overhead door operator is disclosed having a motor, a torque transfer component such as a gear train, and a clutch that is axially movable to engage or disengage the clutch. While the door operator has power, the clutch is engaged to ensure door operator can raise, lower, and stop the overhead door as directed from a remote control. The clutch can be released in the event of a loss of power or by direction from the remote control in which case the clutch releases the shaft of the overhead door. The shaft-mounted overhead door is small, having a width no greater than three times the diameter of the shaft to which it is mounted.

Proposed is a safety apparatus using blocking members, such as rope, for allowing or blocking passage of passengers and pedestrians. The safety apparatus of the present disclosure is configured to reduce a vertical distance of the blocking members when the vertically arranged blocking members are raised to allow passage and increase the vertical distance of the blocking members when the blocking members are lowered to block the passage and reduce a vertical length of the apparatus.
