Abstract: An exercise ball with internal weight with two shell portions, at least one internal plate weight, and at least one strap with engaged with the plate. The shell portions have at least one internal plate relief, and at least one external relief formed on an outer surface of the shell to allow access to an inside of the shells. The plate has at least one alignment aperture for retaining the plate in the internal plate relief of the shell portions, and at least one connection area comprising a slot on the plate to allow the attachment to slide therethrough to retain the plate in the relief of the shell portions. The strap extends outside of the shells through the at least one external relief when the two shells are connected together around the plate.

Abstract: A data access control system is disclosed. The data access control system has a data access control module, comprising computer-executable code stored in non-volatile memory, a processor, a user device, and a peer-to-peer device that stores a user data source. The data access control module, the processor, the user device, and the peer-to-peer device are configured to pair the user device with the peer-to-peer device, use the user device to send an activation command to the peer-to-peer device, store an activation data of the peer-to-peer device on a device ledger, use the user device to send a data command to the peer-to-peer device, and use the peer-to-peer device to send a portion of the user data source to a second device based on the data command. Based on the activation data, the peer-to-peer device rejects commands from all other devices other than the user device.

Abstract: Magnesium aluminate spinels are made by hydrothermally aging an aqueous slurry of a spinel precursor which can be (a) a mixture of boehmite alumina and a magnesium precursor, (b) an aluminum magnesium oxide or hydroxide, and (c) mixtures thereof. At least one of the aged slurries is dried to remove water and produce at least one dried spinel precursor. The dried spinel precursor is then calcined to produce the magnesium aluminate spinel.

Abstract: A medicine ball device having a shell portion with an internal cavity formed therein and an outside surface. A weight is located in the internal cavity. A pair of hand grips extends out of the shell portion at opposite sides thereof. A pair of elongate loop handles extend out of the shell portion from opposite sides of the shell portion, which elongate loop handles pass through the medicine ball device. The loop handles are formed as a strap that engages with the weight to prevent the elongate loop handles from being pulled out of the medicine ball device. A number of attachments accessible from outside of the shell portion are used to attach other devices to the medicine ball device.
