Abstract: A battery operated, wireless mobile data server with an application processing environment and a relational database management system and removable solid-state memory for the distribution and recording of content accessible from clients consisting of multiple mobile devices such as smartphones, tablet computers, notebook computers and other mobile computing devices. The mobile data server can perform processing of application code and perform queries on relational databases and wirelessly provide access to large data sets independently to multiple mobile devices or in coordination to multiple mobile devices, irrespective of the mobile devices' operating systems within a defined geographic range without the use of a cellular infrastructure.

Abstract: A method of fabricating a cartridge for an optical data storage disc includes attaching a plastic shell and a sheet metal cover plate. The shell includes lateral walls and a floor that together define a disc cavity and a plurality of assembly posts. The sheet metal cover plate includes a plurality of holes. To attach the cover plate to the shell, the assembly posts are inserted into the holes, and the ends of the assembly posts are heated to form mushroom caps which hold the cover plate against the shell. The optical disc is housed in the disc cavity, with the data side of the disc facing the cover plate. A sheet metal shutter is wrapped around an edge of the cartridge and over the shell and cover plate.

Abstract: A cartridge for an optical data storage disc includes a monolithic shell and a sheet metal cover plate. The shell includes lateral walls and a floor that together define a cavity that holds an optical data storage disc. The cover plate is attached to the shell, with the cover plate abutting the top surfaces of the lateral walls of the shell. The optical disc is housed in the disc cavity, with the data side of the disc facing the cover plate. A sheet metal shutter is wrapped around an edge of the cartridge and is slideable between an open position, wherein a portion of the optical disc is exposed through a shutter window in the cover plate and a closed position wherein the shutter overlies the shutter window. The cartridge is very strong and is easy to fabricate. The use of sheet metal next to the data side of the optical disc allows the data on the disc to be read or recorded with a very short wavelength laser.

Abstract: A battery-operated, hand-held disc drive for an optical data storage disc contains a radio transceiver. Data read from the disc, for example a game or movie, are delivered to the transceiver and transmitted, preferably using a WiFi protocol, to a host device, such as a smartphone, PDA, ultra-light tablet or notebook computer, or digital TV. Preferably, the compression factor of the data on the disc and the transfer rate of the data from the disc drive to the host device are set such that that disc drive has a low duty cycle, thereby conserving battery power while providing the user with an extended usage period. To provide a high-quality experience, the data on the disc are compressed using a highly efficient data compression algorithm such as MPEG-4.

Abstract: A microminiature optical disc drive is mounted in a cell phone or other handheld portable device to provide a large data source for playing games, movies and other digital content on the device. The optical disc drive is manufactured to an extremely small form factor by, among other things, employing a blue laser beam and a high numerical aperture lens in the optics assembly.

Abstract: A protective enclosure for a cartridge for holding a data storage medium (such as an optical disk) includes a mating cover and base connected to one another with a live hinge having an axis of rotation. The cover contains a lip which surrounds all or part of an enclosure space within the enclosure. The lip mates with a recess in the base to keep dust and debris out of the protective enclosure. Clasps which extend from the cover and base, respectively, mate with each other to maintain the enclosure closed. A number of protrusions extend into the enclosure space and make contact with a data storage cartridge, thereby holding the cartridge in a defined position within the enclosure.
