Abstract: Systems and methods described herein relate to the real-time verification of data purges. A first subprocess of a data purging process is executed to purge a plurality of data items. A system accesses purge result data providing an indication of a result of the first subprocess. The system determines, based on the purge result data, that the first subprocess was not executed in accordance with a purge policy associated with the data purging process. In response to determining that the first subprocess was not executed in accordance with the purge policy, the system adjusts a state of the data purging process. A second subprocess of the data purging process is then executed according to the adjusted state.

Abstract: Systems and methods described herein relate to the efficient handling of data purge requests in the context of a distributed storage system. A plurality of data purge requests is stored in a first data structure. The data purge requests may be grouped into batches that are processed at least partially in parallel. A first data purge request from the plurality of data purge requests is successfully processed, and is moved from the first data structure to a second data structure. Processing of a second data purge request from the plurality of data purge requests is unsuccessful. The second data purge request is retained in the first data structure. Purge status data is generated based on the first data purge request being in the second data structure and the second data purge request being in the first data structure. The purge status data may be presented at a user device.

Abstract: The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus comprises a core housing for accommodating the earphone core; a circuit housing for accommodating a control circuit that drives the earphone core to vibrate to generate a sound, wherein the sound includes at least two resonance peaks; an ear hook for connecting the core housing and the circuit housing; a key arranged at a keyhole on the circuit housing, wherein the key moves relative to the keyhole to generate a control signal for the control circuit; and an elastic pad arranged between the key and the keyhole, wherein the elastic pad hinders a movement of the key towards the keyhole. In the present disclosure, by providing an elastic pad between the key and the keyhole, the waterproof effect of the loudspeaker apparatus may be improved, and the space occupied by the key may be reduced.

Abstract: A system for evaluating cognitive ability of a subject includes a display unit, an input unit, and a way-finding test module including a database and a test processor. The database stores two-dimensional map data and a three-dimensional model of a virtual environment. The three-dimensional model is comprised of surface elements representing features visible in the virtual environment. The test processor is operable to control the display unit to generate a map image corresponding to the two-dimensional map data during an initial stage of a way-finding test. The input unit is operable by the subject during a subsequent stage of the way-finding test to provide control signals to the test processor. The test processor is responsive to the control signals to select the surface elements corresponding to the features in the virtual environment that become visible, and to control the display unit to generate three-dimensional animation.

Abstract: A portal/non-portal image registration system for registering portal and non-portal images includes a user interface, an image preprocessing unit, a contour detecting unit, and an image registration unit. The user interface is operable for selecting points on portal and non-portal images. The image preprocessing unit is operable, with reference to the selected points, so as to adjust orientations and scales of the portal and non-portal images to obtain preprocessed portal and non-portal images. The contour detecting unit is operable so as to reconstruct contours of the preprocessed portal and non-portal images to obtain reconstructed portal and non-portal contours. The image registration unit includes a registering module operable so as to conduct image registration based upon feature information of the reconstructed portal and non-portal contours using Generalized Hough Transform.

Abstract: An electrode driving system for welding device has two mirror image carriages are located side by side to one another and mounted to a main frame. Each carriage has an elongated slider rod therein movable in a reciprocating manner relative to the carriage. The front portion of the slider rod has narrow sections formed by depressions located on its opposite upper and lower edges. A plurality of pairs of jaw elements are pivotally mounted in the carriages. The jaw elements are in contact engagement with the upper and lower edges of the slider rod and they are in a closed position to clamp on or release the clamp on the welding electrode while the carriages are alternately moving back and forth in the reciprocating manner for driving said electrode continuously forward toward a workpiece.

Abstract: Two slidable carriages of identical construction are slidably mounted in a welding device side by side and move alternately 180 degrees out of phase with each other in a linear reciprocating movement. Pivotal gripping plates are mounted on the slidable carriages which alternately clamp on selected gaps between flux coating sections of the welding electrode to advance it continuously towards the work piece. Crank shafts are incorporated in the welding device to produce the linear reciprocating movement of the two slidable carriages, and cam wheels and pivotal bars are provided to locate alternately one group of gripping plates in the closed position to carry the welding electrode forward while the other group of gripping plates are in the opened position to facilitate the welding electrode to advance.
