Abstract: Systems and method may implement a publish/subscribe messaging framework for distributing messages among a plurality of mobile computing devices. A particular “publish/subscribe channel” may be implemented in the context of an auction for one or more items, e.g., collectibles such as trading cards, toys, and/or figurines. The implementation of the publish/subscribe messaging framework may allow for real-time communications of developments in the auction(s) which, in combination with a real-time video stream from a host to a plurality of guests in the channel, amounts to an improved user experience at host devices and guest devices.

Abstract: A convertible wagon/scooter is in the form of a body and step assembly mounted on a set of front wheels and a set of rear wheels. The front wheels are connected to a pivotal mount so that the assembly is steerable. A detachable steering mechanism may be secured directly to the set of front wheels when the assembly is to be used as a wagon. Alternatively the detachable steering mechanism may be mounted to the assembly near the rear thereof and connected to the front set of wheels by a link mechanism when the assembly is to be used as a scooter.

Abstract: A wrist exercise device includes a hollow shaft which houses a pair of compression springs. Tension disks are provided at the remote ends of the springs. The disks are moved toward and away from each other by turning a tension knob at one end of the device to increase or decrease the resistance from a pair of friction pads on each side of a handle at each end of the device. A resistance indicator is provided at one end of the device.

Abstract: A wrist exercise device includes a hollow shaft having a turning disk rotatably mounted at one end thereof. Resistance is provided to oppose the rotation of the turning disk. A turning knob is secured at the opposite end of the shaft for setting the amount of the resistance. Detachable weights are mounted on the device so that the device also functions as a dumbbell.
