Abstract: A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses onto an inner surface of a face sheet of an acoustic inner barrel. The acoustic inner barrel includes an acoustic core comprising an array of hexagonal cells attached to an outer surface of the face sheet that is opposite the inner surface. The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations in the face sheet via emitting laser pulses at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz.

Abstract: A method and system of managing memory, the method including receiving a request for storage space in the memory system; obtaining a timestamp for a new Logical Unit Number (LUN); allocating a range of logical blocks to the new LUN in accordance with its requested size, the range of logical blocks including a starting logical block and a number of blocks; assigning the timestamp to the new LUN as the LUN creation timestamp; and saving the LUN creation timestamp with other metadata identifying the new LUN and the allocated logical blocks. Methods and system for deleting LUNs and using a deletion timestamp are disclosed as is a process to format a LUN.

Abstract: A seat suspension includes a seat support, a base, and a suspension assembly positioned between the seat support and the base. The suspension assembly includes a compressible cushion for containing a gas; and a chamber. The chamber includes a cylindrical hollow member, a front cap at one end of the cylindrical hollow member, an end cap at another end of the cylindrical hollow member, and a piston positioned within the cylindrical hollow member between the front cap and the end cap. The front cap includes an orifice. The orifice provides fluid communication between the cushion and the chamber. When a compressive force causes movement of the seat support portion towards the base, thereby compressing the cushion, the gas from the cushion flows through the orifice into the chamber and directly forces movement of the piston away from the front cap.

Abstract: A seat suspension for boats and other vehicles having a seat support, a base and a suspension assembly positioned between the seat support and the base and permits relative movement between the seat support and the base. The suspension assembly has a first fluid container, a second fluid container, and an orifice member positioned between the first and second fluid containers. The orifice member includes a first orifice in fluid communication with the first and second fluid containers. A piston is positioned within the second fluid container and movable by fluid flowing through the first orifice.

Abstract: A redundancy manager preferably in an I/O adapter has been disclosed to manage commands to peripheral devices in a computer system. These peripheral devices have multiple ports and may have a different bus associated with each port. The buses, referred to as independent pathways, moreover, need not have the same protocol. The redundancy manager determines the number of independent pathways connected to the peripheral device, presents only one logical device to the operating system and any device driver and any other command or device processing logic in the command path before the redundancy manager. For each incoming command, the redundancy manager determines which pathways are properly functioning and selects the best pathway for the command based on load balancing considerations and any ordering semantics that must be preserved in the incoming command and any outstanding commands and associated data that have not yet executed.
