  • Publication number: 20180013748
    Abstract: A method and system for deterring attacks at potential breach points between servers and an account and login server for creating and subsequent verification of accounts. Various cryptographic primitives are used to manipulate passwords to generate verifiers. The verifiers are used with external hardware security modules (HSMs) to eliminate HSMs and intermediate steps between the HSM and login servers as potential breach points.

  • Publication number: 20170354438
    Abstract: Example embodiments of the systems and methods of callus removal disclosed herein comprise a callus catching function to catch the calluses removed by the blade. A clamp on the back side of the blade comprises a hollowed out section into which the blade deposits the removed calluses. The hollowed area may be formed, for example, by a clamp for holding the blade in a handle. In an example embodiment, the clamp may also comprise a pumice sponge for further use in pedicure processes. The clamp may be removable to allow for removal of the collected calluses into a collection bin.

  • Publication number: 20170286714
    Abstract: An online computer system including a database uses an encrypted table that allows for write protection its contents. Middleware logic operating on the system acts as an interface for access to the database, so that any business logic on the system accesses the database through simple procedural calls to the middleware rather than directly to the database itself. The middleware logic abstracts logic that helps implement write protection with the encrypted table. Data to be encrypted that has been traditionally written to other tables is migrated to the encrypted table, where the data encrypted using an authenticated encryption with additional data (AEAD) algorithm. To implement AEAD, the original table, column, and primary key indicating where the data would have otherwise been stored are together used as additional authenticated data (AAD). This tuple of information is also stored in the encrypted table.

  • Publication number: 20170112512
    Abstract: A medical device, configured to perform an endovascular therapy, e.g., thrombectomy, can comprise an elongate manipulation member having a first connection member proximate a distal end of the elongate manipulation member, and an intervention member having a second connection member proximate a proximal end of the intervention member.

  • Patent number: 9480336
    Abstract: The present disclosure describes a seat. The seat may include a stationary support frame at least partially defining a cavity. The seat may also include a backrest cushion, a headrest, and a motion mechanism. The motion mechanism has a headrest assembly allowing movement of the headrest between a retracted position and an extended position. When the headrest is in the retracted position, the headrest is hidden from view within the cavity of the support frame. When the headrest is in the extended position, the headrest is visible above the backrest cushion.

  • Publication number: 20070258085
    Abstract: A substrate illumination and inspection system provides for illuminating and inspecting a substrate particularly the substrate edge. The system uses a light diffuser with a plurality of lights disposed at its exterior or interior for providing uniform diffuse illumination of a substrate. An optic and imaging system exterior of the light diffuser are used to inspect the plurality of surfaces of the substrate including specular surfaces. The optic is held at an angle from a surface normal to avoid reflective artifacts from the specular surface of the substrate. The optic can be rotated radially relative to a center point of the substrate edge to allow for focused inspection of all surfaces of the substrate edge. The plurality of lights can modulate color and intensity of light to enhance inspection of the substrate for defects.

  • Publication number: 20070046510
    Abstract: A method for determining a minimization factor for improving linearity of an analog-to-digital converter including a plurality of components includes the steps of: (a) Evaluating integral non-linearity response of the apparatus to identify significant departures of the response greater than a predetermined amplitude and to relate each respective significant departure with a respective identified component. (b) Determining magnitude of each significant departure. (c) Identifying a trimming factor related with each component. (d) Determining a residual gap magnitude for each significant departure. The residual gap magnitude comprises the magnitude of the respective significant departure less the trimming factor related with the identified component. (e) Determining the minimization factor as a sum of the residual gap magnitudes for a selected plurality of the identified components.

  • Publication number: 20060225349
    Abstract: Relates to a process and apparatus that improves the hydrogen production efficiency for small scale hydrogen production. According to one aspect, the process provides heat exchangers that are thermally integrated with the reaction steps such that heat generated by exothermic reactions, combustion and water gas shift, are arranged closely to the endothermic reaction, steam reformation, and heat sinks, cool natural gas, water and air, to minimize heat loss and maximize heat recovery. Effectively, this thermally integrated process eliminates excess piping throughout, reducing initial capital cost.
