Abstract: A mobile device case having a case body having a cavity configured to receive a mobile device, a plurality of sound channels nested within the case body and a cavity wall associated with the case body, wherein the cavity wall is configured to form a sound chamber within the cavity, wherein the sound chamber is in sound communication with a speaker of the mobile device and the plurality of sound channels, thus allowing sound emitted from the speaker of the mobile device to be guided to the plurality of sound channels. An advantage of the mobile device case is that the plurality of sound channels nested within the case may redirect sound from speakers on the device to allow sound to escape out of the front and back of the mobile device case, thus redirecting sound to a device user and preventing the mobile device case from muffling the sound.

Abstract: A method may include performing, at multiple data partitions, a point-in-time recovery to a specified time by applying transactions that have committed at each data partition up to the specified time. Open transactions that have not been committed at each data partition at the specified time may be identified. A corresponding transaction coordinator may be queried for an outcome of the open transactions. Open transactions that affect a single data partition may be aborted. The point-in-time recovery may be performed at the transaction coordinator partitions by determining the outcome of the open transactions. The transaction coordinator partitions may abort any transaction that remains open subsequent to the point-in-time recovery. If the specified time may be greater than a safety threshold, data up to an earlier point-in-time than specified may be recovered depending on whether there are missing portions of transaction logs at the data partitions or the transaction coordinator partitions.

Abstract: A system includes a data management server and a data store. The data store uses an external file system to store data block of a client virtual machine. The client virtual machine uses an internal file system. The data management server comprises a proxy agent and a staging virtual machine. In response to receiving a request to retrieve a file indexed by the client virtual machine, the proxy agent imports data of the internal file system to a staging virtual machine. The proxy agent determines an internal file address that corresponds to the requested file. The staging virtual machine translates the internal file address to an external file address of the external file system. The staging virtual machine retrieves the file stored in the data store based on the external file address. The staging virtual machine provides the retrieved file to the target device.

Abstract: A Drone Detection System (DDS) listens passively to the Radio Frequency (RF) spectrum for a monitored area. If a drone-like signal is detected, the system alerts for the existence of a drone in the monitored area. This detection system may consist of multiple interconnected software and/or hardware-modules. Each module is responsible for extracting a certain physical feature (i.e., physical layer features) of the received signal (e.g. duty-cycle, bandwidth, power, center frequency, envelope in the time and frequency domains, type of modulation, frame size, etc.). The modular design of the system makes it easier to expand by adding more modules that can measure more physical features of the received signal. If the detector detects a signal with certain physical features, it may alert the existence of this signal along with its physical features and name of the most similar known signal from the library.
