Abstract: Technology is disclosed for recovering the consistency of a RAID (Redundant Array of Independent Disks) metadata database when data corruption is detected in the RAID metadata database. The RAID metadata database includes super sectors, stage sectors, and a data region. Valid data within the data region is a contiguous set of sectors extending from a head sector to a tail sector. In response to data corruption in one of the two super sectors, a set of pointers contained in the other super sector is used to identify the head sector and tail sector. In response to data corruption in both super sectors, the head sector and tail sector are located based on the contents of the sectors in the data region. Techniques are also disclosed for recovering consistency when the data corruption occurs in the stage sectors and/or data region.

Abstract: Technology for configuration metadata recovery that detects a reliability failure regarding configuration metadata stored in non-volatile data storage of a data storage system. The configuration metadata indicates how a metadata database is stored in the non-volatile data storage of the data storage system. In response to detection of the reliability failure regarding the configuration metadata, the technology identifies valid generations of the configuration metadata that are currently stored in the non-volatile data storage of the data storage system, and determines a user-selected one of the valid generations of the configuration metadata. The metadata database is accessed based on the user-selected one of the valid generations of the configuration metadata.

Abstract: A portable electronic device comprises a lower housing including a battery compartment. An upper housing is coupled to the lower housing and is slidable relative thereto in a first linear direction between a closed position and an open position. A battery cover is configured to engage the lower housing and move generally in the first linear direction relative to the lower housing from an unlatched position to a latched position in which the battery cover interlocks with the lower housing and encloses the battery compartment. The battery cover may comprise at least one of a post element or a beam element and the lower housing may comprise at least one of the other of the post element or the beam element. The post and beam elements are configured to interlock with one another when the battery cover is in the latched position.

Abstract: The disclosure relates to a housing for an electronic device. The housing comprises: a back housing defining an interior compartment of the device; a receptacle to receive a first locking feature from a cover for the electronic device; and at least one moveable second locking feature in the receptacle to engage the first locking feature to hold the cover to the back housing. In the back housing the second locking feature is selectively moved from a first engaged position with the first locking feature to a second disengaged position with the first locking feature when a predefined force is applied at a specific location at the back housing or the cover.

Abstract: Embodiments are directed to a methods and systems for nucleic acid detection using enzymatic reactions on a microarray. In one embodiment, a probe comprising a probe nucleotide sequence and a substantially homogenous sequence extender portion is provided on the surface of a microarray. The probe nucleotide sequence is hybridized to the complementary target nucleotide sequence. A solution containing enzymes and detection elements is applied to the hybridized probe structure. The enzyme determines the composition of the nucleotide structure of the extender and creates a complementary homogenous sequence extender structure between the target nucleotide sequence and the microarray surface structure. The detection elements in the solution are bound to the extender structure, thus allowing detection using an appropriate detector system.

Abstract: The present invention relates to the use of split fluorescent proteins to determine whether promoters are coordinately active, whereby the transcriptional expression of incomplete portions of a fluorescent protein is controlled by different promoters and coordinate (not necessarily contemporaneous) promoter activity results in the reconstitution of a fluorescent protein. The present invention, in non-limiting embodiments, may be used to selectively label cells and cell structures in vivo and to demonstrate changes in promoter activity (for example, in developmental biology and drug discovery applications).

The cooling member includes a first cooling unit, a second unit and a cryogenic element. The cryogenic element has a cold surface that contacts the first cooling unit, and a hot surface that contacts the second cooling unit. Since the cold surface of the cryogenic element has a temperature much lower than that of the room temperature, the first cooling unit can thus produce cold and dry air to cool down the electronic apparatus. Meanwhile, the second cooling unit is employed to dissipate heat generated from the cryogenic element.
