  • Patent number: 11212097
    Abstract: A stream of plaintext is marked per its more sensitive parts. These marked parts are being encrypted via mathematically secure ciphers for which the ciphertext may be much larger than the plaintext. This invention creates a mix of size-preserving encryption for the not so sensitive parts of the plaintext, and size-enlarging encryption for the marked parts, thereby security is served without the inconvenience of a very long ciphertext.

  • Patent number: 11199908
    Abstract: A user interface device includes at least a biopotential sensor and a location sensor. The user interface device is constructed to be worn by a person. A responsive device, such as a computer, receives data based on the outputs from the biopotential sensor and the location sensor, and performs actions based on the received data. Primitive gestures detected in the received data are associated with inputs of an operating system of the responsive device. For a wrist-worn device, a primitive gesture can be based on a pose of the hand or location of a wrist or both. The association of primitive gestures with inputs of the operating system can include associating primitive gestures with mouse inputs, inputs to request launching an application or switching applications, or inputs to perform other operations.

    Abstract: Systems, methods, and media are provided for improved targeting of an individual object among a plurality of objects in a multi-player online video game. The video game may include plurality of objects located at various places at a given frame. At each frame, a position of the objects is identified. If a player object (except for the player object associated with the user) is within a predetermined radius of another player object, a target position of the player object is modified relative to other player objects. Next, the target position of the player object is modified towards its original position within the frame. This process is repeated for each player object until the corresponding player object is no longer within the predetermined radius of another player object or a violation of a constraints prevents the modification from being performed.
