Abstract: System and method provide wireless distributed lighting control systems implementing a secure peer-to-peer, self-organizing and self-healing mesh network of actuators and system inputs. The system and method can be designed specifically for indoor and outdoor lighting where actuators include in-fixture, on-fixture and circuit control modules with ON/OFF and full range dimming capabilities, and system inputs include occupancy/vacancy sensors, daylight sensors and switches. A unique messaging protocol facilitates wireless and wired communication between actuators and system inputs, and provides web-based commissioning and monitoring of the lighting control system using a wireless access point accessible from a local network or Internet which can provide an intuitive and easy to use Graphical User Interface (GUI).

Abstract: Error correction in a disk drive is performed by identifying all errors in multiple sectors of a single track during a single read operation. As the data from the track is moved to a buffer, the disk drive records the location of the errors without stopping the read operation. Following the read operation, error recovery is performed on all errors identified in the track. If further error recovery is needed on the track, a subsequent read operation may then be performed.

Abstract: An information storage device (10) includes a cartridge (14) removably inserted into a cradle (13) that has a drive module (18) releasably coupled to an interface module (17). The interface module can be operatively coupled by a cable (12) to a remote system. Communications through the cable conform to an industry-standard protocol. The storage device can receive power from either the cable or an external power source (31). The interface module can detect a change in the source of its operating power during normal system operation, and ensure that this is reported through the cable.

Abstract: An information storage device (10) includes a cartridge (14) removably inserted into a cradle (13) that has a drive module (18) releasably coupled to an interface module (17). A drive electronics circuit (71) in the drive module is coupled to a hard disk drive mechanism (56) in the cartridge, and is coupled through a bus switch (131) and a bus (122) to a bridge circuit (111) in the interface module. An auxiliary circuit (76) in the drive module is coupled to the bus, is controlled by the bridge circuit, operates the bus switch, and handles considerations relating to removability of the cartridge. The interface module is one of several interchangable interface modules which each have a different bridge circuit to interface the bus to a respective different communication protocol.

Abstract: A data storage cartridge (14) can be removably inserted into a drive (13), so that respective connectors (52, 67) move into engagement. Two pawls (81, 82) are biased by a spring (119), and releasably lock the cartridge in its inserted position. In order to remove the cartridge from the drive, a motorized eject mechanism (221) can be actuated and effects movement of an eject member (171), which in turn disengages the pawls from the cartridge, moves the cartridge sufficiently to disengage the connectors, and positions the pawls for insertion of the next cartridge. If the motorized mechanism is not operable, a manual release can be effected by manually inserting a member (291) through an opening (261) provided in the drive housing, and using this member to manually move the eject member.

Abstract: An information storage device (10) includes a drive module (14) releasably coupled to an interface module (13), where an information storage cartridge (11) can be removably inserted into the drive module in an approximately vertical direction. The drive module has a light source and magnifying lens which highlight indica located on the cartridge. Guide structure ensures that the cartridge can be inserted only with a single proper orientation. The drive module includes a display (236) which provides operational status information, and which is visible through an opening (411) provided in the interface module. The interface module has at least two ports (307, 308) conforming to a selected communication protocol, to permit the information storage device to be daisy chained with other compatible devices. A button (301) for initiating cartridge removal is actuated in an approximately vertical direction.
