  • Patent number: 11888935
    Abstract: A cloud-based data protection service is disclosed. In an embodiment, the data protection service may support backup of data sets from one or more sites associated with one or more organizations. In an embodiment, deduplication of backup data across multiple sites of an organization and/or multiple sites associated with different organizations may be supported. In an embodiment, backup data may be post-processed in the cloud to insert fingerprints corresponding to data blocks that did not change since a previous backup was performed, to scan the backup for security threats such as viruses, other malware, personally identifiable information, etc. In an embodiment, restore may be supported from the cloud, where restore blocks may be larger than backup data blocks. In another embodiment, restore may be based on blocks that have changed since the most recent backup (or a user-selected backup).

  • Patent number: 8661634
    Abstract: A method of manufacturing a flexible piezoelectric device including laminating a first metal layer on a silicon oxide layer on a silicon substrate. The method further includes laminating a device on the first metal layer and annealing the first metal layer to oxidize the first metal into a first metal oxide. The method further includes etching the first metal oxide to separate the device from the silicon oxide layer and transferring the separated device to a flexible substrate using a transfer layer. The metal oxide layer laminated on the silicon substrate is etched to separate the device from the substrate. As a result, physical damage of the silicon substrate is prevented and a cost of using expensive single-crystal silicon substrate is reduced.

  • Publication number: 20110000060
    Abstract: Provided are a method for manufacturing a flexible device, a flexible device, a flexible piezoelectric device and a flexible capacitor manufactured by the same, and a method for manufacturing a flexible sensor. A method for manufacturing a flexible device includes: laminating a first metal layer on a silicon oxide layer on a silicon substrate; laminating a device on the first metal layer; annealing the first metal layer to oxidize the first metal into a first metal oxide; etching the first metal oxide so as to separate the device from the silicon oxide layer; and transferring the separated device to a flexible substrate using a transfer layer. According to the disclosed method for manufacturing a flexible device, differently from the prior art where the silicon substrate itself is etched, the metal oxide layer laminated on the silicon substrate is etched to separate the device from the substrate.
