The present invention provides a portable electric lift apparatus for trailer bed legs. The electric lift apparatus comprises a housing unit and a control module. The housing unit includes a motor, a battery source which is electrically connected to the motor, a sleeve, and a connection tube attached to the sleeve. The sleeve has teeth located in the circumstances of the sleeve and the connection tube has teeth located in one end of the tube. The teeth on the connection tube are meshed with the teeth of the sleeve. The control module includes multiple control buttons, one of the buttons controlling an upper ward lifting movement of the lift apparatus and another one of the buttons is for controlling a downward movement of the lift apparatus.

An apparatus for use in positioning a trailer includes an autonomous unit connectable with the trailer and having at least one wheel. A sensor unit connected to the autonomous unit determines the position and/or speed of the autonomous unit. A controller receives the at least one signal from the sensor unit and controls the direction and/or speed of movement of the autonomous unit.

Methods, systems, and computer program products for driving anomaly detection based on spatio-temporal landscape-specific driving models are provided herein. A method includes generating, for each of multiple users, a temporally-related driving skill model pertaining to one or more landscapes, wherein the model is based on temporally-related driving data associated with the users and landscape-related information of trips driven by the users; monitoring the users participating in a ride-sharing trip in a vehicle by analyzing ride-sharing trip data; detecting driving-related anomalies attributed to the monitored users by comparing the ride-sharing trip data and the respective temporally-related driving skill model for each monitored user; updating a schedule for the trip based on the detected anomalies and estimated conditions attributed to remaining portions of the trip by modifying an assignment of selected users to drive the vehicle during the remaining portions of the trip; and outputting the updated schedule to the selected users.

A method for reverse maneuvering a flat-towed dinghy attached to a towing vehicle. A carrier includes a platform, two caster wheels, and a drag mechanism. The drag mechanism is configured to present greater resistance to lateral movement than the two caster wheels. When the front tires of a flat-towed dinghy are loaded onto a pair of carriers, the dinghy is maneuvered in reverse without the dinghy front wheels reverting to the maximum turn that is normally caused by the dinghy front wheel steering caster angle. The dinghy rolls onto the carrier when the flat-towed dinghy is moved in the backward direction. A chock or stop device prevents the front tire from rolling off the platform when the flat-towed dinghy is moving in the backward direction. The dinghy rolls off the carrier when the dinghy is moved in the forward direction.

A cluster transfer robot includes a body, two clamping arms arranged at the bottom of the body, and a first driving mechanism arranged at the bottom of the body. The first driving mechanism includes a driving wheel configured for driving the transfer robot to move. The clamping arm includes a second driving mechanism and a rotating assembly connected to the second driving mechanism, the rotating assembly includes a rotating arm rotatably connected to the body and a supporting wheel arranged on the rotating arm for supporting the transfer robot, the rotating arm is provided with a clamping portion for clamping automobile tire, and two clamping portions of two rotating arms are arranged facing to each other to define a clamping space for the automobile tire when the two clamping portions are close to each other. The cluster transfer robot can greatly reduce the construction cost of intelligent parking lots.

A vehicle lift system and vehicle dolly system are provided. The vehicle lift system includes a vertically extending portion, a stationary base portion extending horizontally from the vertically extending portion, a vertically movable vehicle support portion extending horizontally from the vertically extending portion and configured to support a vehicle dolly; and a lifting member coupled to the vehicle support portion and configured to elevate the vehicle support portion.
