Abstract: A storage switch is disclosed that facilitates mirroring of data. For example, a target is mirrored when an identical (or almost identical) copy of the data is stored in two or more separate physical data stores. Because the various data stores may not be homogenous, they may provide for different burst sizes. To accommodate the different burst sizes, the switch provides different sequence counts for data packets sent to the different data stores that store the mirrored data.

Abstract: A switch including a processor and method for monitoring bandwidth in the storage switch. The switch includes at least one physical port coupling at least one target and at least one initiator via the physical port. The monitoring method may include the steps of determining whether congestion occurs on the physical port and assigning a weight to bandwidth usage between the initiator and the target based on a minimum and maximum bandwidth settings for each target. The switch may further include a step of controlling bandwidth usage by each of said at least two targets based on minimum and maximum bandwidth settings for each of the targets.

Abstract: In a personal media player, a slide and click combination switch enables several operational functions to be integrated into a single interface. The operational functions include user control lock and power state management. The combination switch includes a button that is arranged to laterally slide between two discrete switch positions (locked and unlocked) as well as move axially between unactuated and actuated positions against a spring force that is normally biased towards the unactuated position. When the button in the combination switch is slid to the locked position, the button cannot be actuated, the user controls on the player are disabled, and the power status of the player (i.e., either on or off) is maintained in its current state. When the button is slid to the unlocked position, the user controls on the player are enabled, and the button may be actuated to implement different device power management scenarios.

Abstract: Systems and methods can provide mirrored virtual targets and online synchronization and verification of the targets while avoiding deadlock, inconsistencies between members of the target, and false verification failures. A lock within the storage switch can limit the number of outstanding commands for a physical target to one during synchronization and verification operations. In one embodiment, a lock can be implemented as one or more resource tables maintaining an indication of the number of transfer ready signals available from physical targets. During typical write operations, deadlock can be avoided by determining whether each physical target for the mirrored operation can issue a transfer ready signal prior to issuing a command to the physical target. When a synchronization or verification operation begins, the maximum available number of transfer ready signals for each target can be decremented to one in order to limit the total number of outstanding commands for each target to one.

Abstract: Systems and methods in accordance with various disclosed embodiments can manage a mirrored virtual target to synchronize the members of the virtual target and/or to verify that the members of the virtual target are synchronized. In one embodiment, a mirrored virtual target is synchronized by first provisioning at least one first internal virtual logical unit (IVLU) corresponding to at least one destination target of the mirrored target and a second IVLU corresponding to a source target of the mirrored target. A write command is first issued, via one or more internal virtual logical units, to each of the destination target members of the mirrored target. When each destination target is available to receive data, as evidenced by a returned transfer ready signal, a read command is provided to the source target via the second internal virtual logical unit. In this manner, a data path between the source and destination targets is established prior to reading data from the source target.

Abstract: Systems and methods in accordance with various embodiments can detect and alleviate potential or actual deadlock of a storage switch or storage area network when attempting to write data to a mirrored virtual target. In accordance with one embodiment, a timer is started when a storage switch routes a write command to the physical targets corresponding to a virtual target of the write command. If each physical target does not return a transfer ready resource within a predetermined timeout period, the switch determines that a potential or actual deadlock has occurred. An abort command is sent to each of the physical devices. The abort command can clear the command from the targets and also free any allocated transfer ready resources. After receiving an acceptance response from each physical target, the state of the write command at the switch can be cleared. The write command can then be re-issued to the physical devices.

Abstract: A device has a moving display that alternatively hides two keyboards. As the display is moved to expose one keyboard, the device may take on different functionality than when the other keyboard is exposed. The sliding mechanism has a back plate with two guides, onto which are mounted the two keyboards. A sliding plate engages has at least two legs that engage the guides. Electrical signals are passed from components attached to the sliding plate to components attached to the back plate through signals routed along one of the sliding plate legs. A loop of cable is able to roll beneath the keyboard when the sliding plate is moved from one position to another. A spring may also be used between the sliding plate and back plate to hold the sliding plate at either extreme of its travel.

Abstract: Disclosed are promotional products such as buttons, badges, toys, signs, and displays, and in particular promotional products that display inscriptions vertically, no matter the orientation of the product, more particularly words or phrases spelled the same forwards as backwards, as for example BOB or MOM or WWW. The products each have a rotatable shaft connected to a base member, and a plurality of sheets imprinted with inscriptions and attached by pins onto the base member so that the sheets hang vertically. As the shaft rotates, the base member rotates but the sheets continue to maintain a vertical position.
