  • Using a digital certificate with multiple cryptosystems
    Patent number: 9660978
    Abstract: In a general aspect, a digital certificate can be used with multiple cryptography systems (“cryptosystems”). In some cases, the digital certificate includes a public key field, which contains a first public key of an entity. The first public key of the entity is associated with a first cryptosystem. The digital certificate includes a signature value field, which contains a first digital signature of a certificate authority. The first digital signature is associated with the first cryptosystem. The digital certificate includes an extension. The extension contains a second public key of the entity, a second digital signature of the certificate authority or both. The second public key is associated with a second cryptosystem, and the second digital signature is associated with the second cryptosystem.

  • Protective Painting Shield for Circular Fixture Junctions
    Publication number: 20170066007
    Abstract: A protective collar for temporarily protecting an item from paint on a surface that is being painted. The protective collar is formed as a band having a convex surface and a concave surface. The band has a uniform thickness between the convex surface and the concave surface in the primary areas that are not tapered. The band embodies a spring bias that biases the band into a circular configuration. The first end and the second end of the band are tapered. Additionally, the band is tapered along its length adjacent a first long edge. This causes the first long edge to be thinner than the opposite second long edge. The tapered regions minimize the footprint of the spring collar on a surface.

  • WEIGHT LIFTING BENCH
    Publication number: 20170028246
    Abstract: A hydraulic cylinder assembly for operating a weight lifting bench and other equipment. The hydraulic cylinder assembly comprises a hydraulic cylinder containing a hydraulic fluid, an accumulator containing a pressurized compressible fluid, and a flow control valve assembly interposed in a flow path therebetween. The flow control valve includes an axially reciprocating piston defining a flow control orifice and an axially movable plunger received in the orifice. Movement of the plunger operates to engage and open a ball check valve which in turn opens the flow path allowing hydraulic fluid to flow from the hydraulic cylinder to the accumulator. The working end may be stepped and positionable between first and second axial positions relative to the orifice to define first and second flow areas via movement of the plunger. Reciprocating movement of the piston opens and closes the flow path.

  • ADJUSTABLE ANGLE WEIGHT LIFTING BENCH
    Publication number: 20170001064
    Abstract: An adjustable weight lifting bench includes a frame, a seat pad, and a back pad. The back pad is pivotably coupled to the frame about a first pivot axis and angularly adjustable between a plurality of user-selectable incline and decline positions. A hydraulic mechanism supports the back pad in the incline and decline positions. A movable operating lever operably coupled to the hydraulic mechanism operates to change the mechanism between an activated condition in which the back pad is movable and a deactivated condition in which the back pad locks into a selected one of the positions. When the mechanism is in activated condition, applying pressure against the back pad the lowers the back pad and removing the pressure raises the back pad. In one embodiment, the mechanism automatically raises the back pad when the pressure is removed and the mechanism is in the deactivated condition.

  • Method and apparatus for providing enhanced streaming content delivery with multi-archive support using secure download manager and content-indifferent decoding
    Patent number: 9516083
    Abstract: A system, apparatuses and methods are provided to download and process data and other content streamed over a wide area network using one or more dynamically fetched, material specific, data handlers (e.g., download assistants). A download assistant fetches a data stream from a remote location and processes the streamed data iteratively using buffers and multi-threaded processes through the decoder (e.g., codec), allowing source material-specific processing of the data as it is streamed from one or more download sources as well as content-indifferent and platform-indifferent decoding. To minimize versioning issues, payload construction for secure delivery is simplified to packing and encrypting a directory tree containing any number of files or other digital media into an archive and, when needed, dividing a payload into multiple files or archives with a descriptor that lists the archives.

  • System and method for remote reset of password and encryption key
    Patent number: 9425957
    Abstract: Data is secured on a device in communication with a remote location using a password and content protection key. The device stores data encrypted using a content protection key, which itself may be stored in encrypted form using the password and a key encryption key. The remote location receives a public key from the device. The remote location uses the public key and a stored private key to generate a further public key. The further public key is sent to the device. The device uses the further public key to generate a key encryption key, which is then used to decrypt the encrypted content protection key. A new content encryption key may then be created.
