Metadata-based data loss prevention (DLP) for cloud resources
The technology disclosed proposes a metadata-based solution to prevent malicious data egress resulting from resource-level transactions. In advance of the data egress requests, the technology disclosed crawls an organization's accounts on different cloud storage services and makes a resource list of different cloud-based resources configured under the organization's accounts. The resource list is then stored in a metadata store. When an inline proxy receives a resource-level transaction that is requesting to move a cloud-based resource outside the organization's account, the proxy looks up the metadata store and determines whether the resource-level transaction is attempting to manipulate any of the cloud-based resources listed in the resource list. If so, then the proxy blocks the resource-level transaction. |

Angle detection apparatus, rotation amount specification unit, and rotary driving unit
Provided is an angle detection apparatus making it possible to reduce the labor of manufacturing while also suppressing bulkiness.The angle detection apparatus includes a first rotating body (120), a second rotating body (122), a first transmission mechanism (111) that causes the second rotating body (122) to rotate by reducing a speed of a rotation of the first rotating body (120), a first angle detector (Ds) that detects a rotational angle of the first rotating body (120), another second angle detector (Dm) that detects a rotational angle of the second rotating body (122), and a processor (40) that specifies a number of revolutions (Rs) of the first rotating body (120). The processor (40) specifies the number of revolutions (Rs) while dynamically varying a specification condition for specifying the number of revolutions (Rs) according to a numerical value decided according to the detected rotational angle of the first rotating body (120) and a reduction ratio (G1) of the first transmission mechanism (111), and the detected rotational angle of the second rotating body (122). |

Portable apparatus for generating electricity
A portable apparatus for generating electricity is provided comprising an electrical energy-generating device for generating electrical energy in response to input mechanical action. The apparatus comprises a drive mechanism having an elongate flexible member provided as a closed endless loop. A portion of the elongate flexible member is exposed so as to enable a user to grasp and pull said portion downward by a distance of at least 30 cm. The drive mechanism supplies the said mechanical action to the electricity-generating device, wherein said mechanical action is provided by user applying a downward force to the elongate flexible member so as to cause the elongate flexible member to move with respect to the mounting element. A re-chargeable battery is further provided for storing the electrical energy generated by the electrical energy-generating device. A mounting element enables the apparatus to be supported at a suspended position relative to the ground during use. |
