    Abstract: Embodiments of a flexible electroluminescent (FEE) device are described. An FEE device includes a device stack with a quantum dot (QD) film configured to generate a first light having a first peak wavelength and a flexible substrate configured to support the device stack and emit a first portion of the first light. The FEE device further includes an encapsulation layer disposed on the device stack and an outcoupling layer disposed on the flexible substrate. The encapsulation layer can be configured to provide mechanical and environmental protection to the FEE device from moisture or oxygen. The outcoupling layer can be configured to prevent total internal reflection of a second portion of the first light within the flexible substrate and extract the second portion from the flexible substrate.

  • Patent number: 12059773
    Abstract: Systems and methods include providing a coated abrasive article with a substrate formed from a plurality of hygroscopic fibers, an abrasive layer comprising a make coat, a size coat, a supersize coat, or combinations thereof disposed on a first side of substrate, and an anti-curl layer disposed on a second side of the substrate. The polymer-based anti-curl layer allows the coated abrasive article to achieve a change in curl between ?5 millimeters and 25 millimeters, the change in curl being expressed as the curl of the coated abrasive article in millimeters at 90% relative humidity minus the curl of the coated abrasive article in millimeters at 20% relative humidity. The coated abrasive article exhibits substantially no loss of grinding performance, burst speed, or a combination thereof as compared to coated abrasive articles free of the anti-curl layer.

  • Patent number: 11507482
    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.

  • Publication number: 20220129437
    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.

  • Publication number: 20110003703
    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.

  • Patent number: 7190576
    Abstract: An internally disposed cooling device is provided. The cooling device includes a cooling member and a docket member. 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.

  • Publication number: 20060011329
    Abstract: A heat pipe heat sink with a holeless fin module is disclosed in the present invention. Because of the holeless arrangement the heat pipe heat sink is much more convenient for manufacturing. The heat generated by an electrical component can quickly be transferred into the heat pipe and uniformly distributed to each of the heat dissipating fins. The heat pipe heat sink includes a heat dissipating fin module, a heat conducting member, one or more heat pipes installed on the heat conducting member, and a heat conducting plate which is thermally connected to the heat conducting member and the electrical component. The end surface of the heat conducting member with the heat pipe installed thereon is convenient for application of an adhesive because the end surface and the pipe wall of the heat pipe are exposed outside of the heat dissipating fin module before any combination takes place.
