Title: Structure and method for storing data on optical disks
Inventor: PLEISS CURTIS M
IPC: G11B27/30
Filed: 2001-03-27
Granted: 2002-09-11
Abstract: During manufacturing of optical disks, mastering equipment inserts marks (""high frequency wobble marks"" or ""HFWMs"") into the wobble of the groove on optical disks to store data. The presence of a HFWM at a zero crossing of the wobble indicates an active bit and the absence of the HFWM indicates an inactive bit. The zero crossing is, for example, a negative zero crossing. A matched filter is used to detect the shape of the HFWMs. If a HFWM is detected during a wobble cycle, an active bit is saved in a register or a memory. If a HFWM is not detected during a wobble cycle, an inactive bit is saved in a register or a memory. The active and inactive bits may be coded bits that must be decoded to data bits. The data bits include information such as a synchronization such as a synchronization mark, a sector identification data, and an error detection code.

Title: Method and apparatus for medium access control in powerline communication network systems
Inventor: GARDENER STEVEN HOLMSEN
IPC: H04L29/06
Filed: 2001-08-01
Granted: 2002-12-11
Abstract: An inventive medium access control (MAC) protocol for powerline networking systems is described. The inventive MAC protocol controls access to and use of a physical medium (power lines) in a powerline networking system. The MAC protocol method and apparatus includes a method of providing ""blanking intervals"" in which devices using newer versions of the protocol ""clear out"" earlier version devices. The use of blanking intervals greatly eases backward compatibility of the network when the protocol is upgraded with new versions. The method of using blanking intervals is closely coupled to a technique of using ""beacons."" The beacons are used to propagate blanking interval information throughout the network. The beacons also include a mechanism for informing devices of the expiration of blanking information. The MAC also includes a method of establishing and maintaining ""virtual circuit"" connections between selected devices on the network. The virtual circuits can be established in powerline networking systems not having a central controller. A method of assigning unique Logical Network Identifiers (LNIs) to logical networks in the powerline networking system is also described. The LNIs uniquely identify each of the logical networks in the network. A means for creating, managing and distributing network encryption keys is also described. The encryption keys are used by the devices in the powerline networking system to prevent data from being shared with unauthorized users.
