A parking brake and anti-theft apparatus as described herein may include a brake assembly, a linear actuator and a plurality of locking pins. The brake assembly may include a rotor plate. The rotor plate may include a plurality of openings in and/or through the rotor plate. The plurality of locking pins may be extendable by the linear actuator. The pins may be aligned perpendicular to a face of the rotor plate such that, as at least one of the pins is disposed over one of the plurality of openings and the actuator extends the plurality of locking pins, the pin disposed over the one of the plurality of openings passes into the one of the plurality of openings. In various embodiments, the plurality of pins may comprise a length equal to or greater than a length between two adjacent openings of the plurality of openings.

A secure locking hub system for locking a wheel hub of a trailer to a fixed axle of the trailer is provided. The system has a locking ring that may be moved between a locked and unlocked configuration. When locked, the hub is in a rotationally fixed position relative to the axle on which the hub is mounted. With the hub locked to a fixed axle, the trailer cannot be moved when locked. The system additionally has a security lock that secures the locking ring in place in order to prevent any unauthorized individual from unlocking the hub and stealing the trailer.

An anti-theft device configured to be installed around at least a portion of the perimeter of the vehicle wherein the present invention inhibits access to the area underneath the vehicle. The anti-theft device includes a first rail member and a second rail member that are identically constructed and deployed on opposing sides of the vehicle. The first rail member and second rail member include upper longitudinal support members and lower longitudinal support members. A plurality of vertical support members are intermediate the upper and lower longitudinal support members having a void therebetween of sufficient size to inhibit a human from traversing therethrough. The present invention can further be deployed with front and rear rail members built similarly to the first and second rail members. Tire platforms are hingedly secured to the first and second rail members and are configured to have tires of a vehicle superposed thereto.

Disclosed are an article use control method, device and system and an article. The article use control method includes: providing an article in an available state, the article having a unique article identifier; when detecting an event that the article is used by a user, starting up a timer to count down to wait for an article use authentication result based on the article identifier and a user identifier of the user who uses the article, the user identifier uniquely identifying the user; and when the article use authentication result is not acquired or the authentication is failed before the countdown ends, changing the article from the available state to a disabled state. According to the present invention, a user can use an article before performing an authentication operation. Moreover, during the use of the article by the user, article use authentication is completed in a user-unperceivable manner. The user experience is improved.

A tamper resistant device for an appliance for preventing unauthorized access to and manipulation of the controls for a water heater or the like. The tamper resistant device for an appliance includes a support assembly adapted to secure about a back of a control unit of an appliance and a cover member removably securable to the support assembly and adapted to cover the control unit of the appliance.

An anti-theft device of an operational vehicle, in which an operation of cancelling an anti-theft mode is simply and easily performed, is provided. The anti-theft device includes: a travel regulation unit (70) which maintains, when the anti-theft mode is set, the operational vehicle (1) in a state where the operational vehicle (1) cannot travel; and a wireless operation terminal (80) which wirelessly operates an operational device (20). When the wireless operation terminal (80) communicates with a controller (70), the wireless operation terminal (80) performs identification authentication, and when the identification authentication between the wireless operation terminal (80) and the controller (70) is successfully performed, the travel regulation unit (70) cancels the anti-theft mode. Since the wireless operation terminal (80) is only made to communicate with the controller (70), and thus the anti-theft mode is cancelled, the operation of cancelling the anti-theft mode is simply and easily performed.

A multi-diameter clamp for clamping on tires of different sizes is provided. The multi-diameter clamp comprises at least one clamping unit, at least one actuator, and at least one sensing unit. The at least one clamping unit further includes at least one movable member and a fixed member. Wherein the at least one movable member moves within a tire housing space having a starting position and a clamping position. The tire housing space locates between the movable member and the fixed member for clamping on a tire. The at least one actuator connects to the at least one movable member, and enables the at least one moveable member to move between the starting position and the clamping position. The at least a sensing unit obtains a diameter size of the tire, and based on the diameter size, actuates the at least one actuator corresponding to the diameter size.
