  • Publication number: 20090173139
    Abstract: A method of detecting impact damage of a structure having a first surface exposed to potential impacts from an object comprises providing a sensor having a body portion that has a surface provided with an elongated channel. The sensor is fixed to a second surface of the structure such that a conduit is formed by the channel and the surface. The surface is on an opposite side of the structure to the first surface. A pressure differential is established between the conduit and a reference pressure adjacent the conduit. Monitoring is conducted for detecting any change in the differential pressure that may be indicative of a fracture or crack propagating in the second surface.

  • Publication number: 20090125671
    Abstract: An apparatus, system, and method are disclosed for storage space recovery after reaching a read count limit. A read module reads data in a storage division of solid-state storage. A read counter module then increments a read counter corresponding to the storage division. A read counter limit module determines if the read count exceeds a maximum read threshold, and if so, a storage division selection module selects the corresponding storage division for recovery. A data recovery module reads valid data packets from the selected storage division, stores the valid data packets in another storage division of the solid-state storage, and updates a logical index with a new physical address of the valid data.

  • Patent number: 7533351
    Abstract: A set of replacement system window controls is provided that are instantiated as the result of the receipt of create control messages into the system message queue, instead of the built-in system window controls. The replacement window controls result in replacement control instances being created with modified properties based on user preferences. The replacement system window control instances may also include an overlay function. In response to a set focus message, a replacement control instance may create an overlay control that is displayed over the replacement control. The overlay control itself can have modified properties and may be enlarged or relocated. When the overlay control receives a release focus message, the overlay control passes its state back to the replacement control and is destroyed.

  • Publication number: 20090113994
    Abstract: A method for detecting separation in a structure that comprises at least two portions or layers affixed together comprises forming a cavity into the structure that passes through an interface formed between the two portions and plumbing the cavity to a monitoring system. A pressure differential is established between the cavity and a reference pressure to which the structure is exposed. A monitoring system monitors for a change in the pressure state of the cavity. Changes in the pressure state are indicative of a separation between the portions or layers.

  • Patent number: 7515994
    Abstract: An accurate blending module for adjusting the pH of solutions containing therapeutic proteins includes a recirculation loop that receives the therapeutic protein solution via a feed pump and an acid solution via an adjusting pump. The recirculation loop includes a recirculation pump and a pH sensor that detects the pH of the solution in the recirculation loop. A controller communicates with the pH sensor and the adjusting pump. The adjusting pump adds acid to the recirculation loop based on the pH readings taken by the pH sensor. The recirculation pump recirculates the therapeutic protein solution and acid in the recirculation loop so that it is mixed. As a result, the pH of the therapeutic protein solution is precisely controlled and adjusted in a non-destructive fashion.

  • Publication number: 20080183953
    Abstract: An apparatus, system, and method are disclosed for storage space recovery in solid-state storage. A sequential storage module sequentially writes data packets in a storage division. The storage division includes a portion of a solid-state storage. The data packets are derived from an object. The data packets are sequentially stored by order of processing. A storage division selection module selects a storage division for recovery. A data recovery module reads valid data packets from the storage division selected for recovery, queues the valid data packets with other data packets to be written sequentially, and updates an index with a new physical address of the valid data. The index includes a mapping of physical addresses of data packets to object identifiers. A storage division recovery module marks the storage division selected for recovery as available for sequentially writing data packets in response to completing copying valid data from the storage division.
