A63B 21/00

US Classification:

482 8, 482 9, 482 51, 482900

Abstract:

A method and apparatus for providing speed controlled eccentric exercise which include an exercise apparatus having an engagement member for engaging a user's body where the engagement member is moveable in opposite directions, means for enabling the engagement member to exert a force in a first direction at a predetermined speed, means for detecting change in the predetermined speed or pressure of the force after a user applies a force to the engagement means in a direction opposite the first force, and means for adjusting the apparatus supplied force and user supplied forces to equal one another or to maintain the predetermined speed.

Gregory Dimitri Volan - Longmont CO, US

Assignee:

Vmedia Research, Inc. - Boulder CO

International Classification:

G11B 17/03

US Classification:

720630

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.

Gregory Dimitri Volan - Longmont CO, US

Assignee:

Vmedia Research, Inc. - Boulder CO

International Classification:

G11B 17/03

US Classification:

720630, 711111

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.

International Classification:

G11B 23/03

US Classification:

720738

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 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.

Assignee:

International Classification:

G11B 23/03

US Classification:

720736

Abstract:

A user-removable optical data storage system is provided. A rotatable first-surface medium is enveloped in a cartridge. The cartridge provides relatively large data capacity such as about 0. 25 Gbytes or more despite a relatively small size such as about 35 mm×35 mm×3 mm. Preferably the cartridge substantially seals the data surfaces of the medium when the cartridge is withdrawn from a drive and at least a portion of one surface is automatically exposed to the objective of an optics arm when said cartridge is inserted in the drive. Tracking involves rotating an optic arm about an axis parallel to the disk rotation axis. Focus can involve pivoting the arm about an axis parallel to the disk surface.
