In a method for monitoring an electromagnetically actuable brake, which has an energizable coil that interacts with a tractive electromagnet situated so as to be linearly movable, and a vehicle having an electromagnetically actuable brake, the current flowing through the coil is acquired, the acquired current value in particular being conveyed to an evaluation unit, the voltage applied at the coil is intermittently increased, and a relative position of the tractive electromagnet with respect to the coil is determined from the thereby induced current characteristic, in particular the characteristic of the current rise, it is particularly determined from the ascertained position whether the brake is in the applied state or in the released state, the tractive electromagnet in particular is arranged as a permanent magnet or has a permanent magnet.

The disclosure relates to a medical imaging supply transport cart having enhanced safety features and a process implementing the same. The medical imaging supply transport cart includes a support surface configured to support medical imaging supplies, the support surface further configured to support a support mechanism, and the support mechanism further configured to support the medical imaging supplies. The support mechanism further configured to rigidly hold the medical imaging supplies with a first holding mechanism, the medical imaging supplies configured to store at least one dose of a nuclear medicine, a plurality of wheels arranged below the support surface, at least one door configured to enclose the medical imaging supplies, and a handle configured to be grasped by a user to guide the medical imaging supply transport cart.

An Urban Intermodal Freight System is capable of transporting large volumes and tonnage of freight by containerized or other means on a mass transit rail system. It captures excess capacity in the existing mass transit rail infrastructure to move packages, parcels, and freight by using miniaturized intermodal cargo containers that are designed to integrate seamlessly with the existing transit infrastructure, while displacing delivery trucks from increasingly crowded city streets. By enabling inbound trucks to transfer their cargo to the Urban Intermodal Freight System at a city's outskirts, freight is delivered without trucks entering congested downtown areas, greatly alleviating traffic congestion, delays, greenhouse gas emissions and other negative environmental impacts. The Linear Loading Dock and Conveyor System may have other useful applications, for example to access a facility, building or vehicle, or in other circumstances where off street truck parking or loading docks are not available.

Provided are mechanical braking systems for wheeled trolleys, trolleys including a mechanical braking system and methods for controlling movement thereof.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

A caster wheel brake system for a mobile support system such as a cart or other wheeled structure is operable to selectively secure caster wheels against rolling rotation. The system includes a caster wheel assembly and a braking mechanism mounted nearby. A pair of brake actuation inputs, such as handles or levers, can be secured to the cart and independently operated to rotate a rotator link, which in turn rotates a brake-actuating link. Rotation of the brake-actuating link deactivates the braking mechanism to allow rolling rotation of the caster wheels. Optionally, the operation of one of the handles to deactivate the braking mechanism has no effect on the other handle.

A system for monitoring and controlling shopping cart usage comprises a wheel assembly that attaches to a shopping cart. In some embodiments the wheel assembly includes a wheel, a brake that can be activated to inhibit rotation of the wheel, a controller that controls the brake, a VLF receiver, and an RF transceiver. The RF transceiver may, for example, operate in a 2.4 GHz frequency band. In some implementations, the RF transceiver may be used to detect entry of the shopping cart into a checkout area of the store, and the VLF receiver may be used to detect that the shopping cart is exiting the store. The controller may activate the brake if the shopping cart attempts to exit the store without first passing through a checkout area.
