Abstract: A solid particle flow distribution controller includes an extension skirt configured to be mounted to a discharge skirt at a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The extension skirt includes a plurality of circumferential segments. Each segment is movably mounted to the discharge skirt for movement in an upstream and downstream direction with respect to the discharge skirt. The segments of the extension skirt are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the discharge skirt as needed to improve solid particle distribution among the downstream pipes.

Abstract: A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.

Abstract: Certificate remoting and recovery may be provided. A computer may identify required security certificates and determine whether at least one required security certificate is not available. If the certificate is not available, the computer may identify a peer server and request the missing certificate from the peer server. The computer may also be operative to receive certificate management instructions from other computers.

Abstract: A method, non-transitory computer readable medium, and apparatus that generates preorder information identifying a plurality of consumer items to be prepared at designated begin times, based at least in part on historical purchase information. At each of the designated begin times a ticket is generated identifying a consumer item, wherein the consumer item has an associated duration such that the consumer item will be ready at a finished time. Each ticket is provided to a client computing device, wherein the tickets further include at least a remaining amount of time until the identified consumer item reaches the finished time. A request is received from the client computing device to claim one of the consumer items identified by one of the provided tickets. Each of the claimed consumer items is associated with a claimed status. The historical purchase information is updated based on the request.

Abstract: A guide bushing for a tensioning rod in a vertical pulverizer includes a bushing body having a substantially cylindrical interior bushing surface configured and adapted to moveably engage a tensioning rod of a vertical pulverizer. The bushing body is divided circumferentially about the bushing surface into a plurality of sections joined together. The sections are configured and adapted to separate from one another for installation and removal of the bushing body about a tensioning rod of a vertical pulverizer.

Abstract: This invention is related to the fields of organic chemistry and nanotechnology. In particular, it relates to materials and methods for the preparation of organic synthons and bridged macrocyclic module components. The bridge macrocyclic module compounds may be used to prepare macrocyclic module compositions such as nanofilms, which may be useful for filtration.

Abstract: Single-use character combinations are a secure mechanism for user authentication. Such “one-time passwords” (OTPs) can be generated by a mobile device to which the user otherwise maintains easy access. A key exchange, such as in accordance with the Diffie-Hellman algorithm, can provide both the mobile device and a server with a shared secret from which the OTPs can be generated. The shared secret can be derived from parameters posted on the server and updated periodically, and the mobile device can obtain such parameters from the server before generating an OTP. Such parameters can also specify the type of OTP mechanism to be utilized. A second site can, independently, establish an OTP mechanism with the mobile device. For efficiency, the first server can provide an identity token which provides the mobile device's public key in a trusted manner, enabling more efficient generation of the shared secret with the second server.

Abstract: A liquid injection and ratio control system is provided for blending an additive into a main flow line at a controlled ratio. The system automatically detects variances in temperature, pressure, and additive concentration and provides compensation thereto. The system also provides for automatic flow detection, calibration responsive to a level gauge, automated data collection, and wireless bi-directional communication.

Abstract: An apparatus is presented in which a sample can be accurately repositioned in a spectroscopic and/or imaging apparatus upon multiple insertions, and where the apparatus can be worn by living subjects for extended periods of time. The apparatus additionally reduces the temperature increase and stabilizes the temperature of the sample upon irradiation with an optical source of excitation. Additionally, the apparatus stabilizes the pressure and critical optical properties of the sample and its interface with the apparatus. Alternatively or additionally, the apparatus can be used to alter and/or substantially reduce fluorescence from targeted fluorophores in the sample.

Abstract: The principles of the present invention relate to systems, methods, and computer program products for more efficiently and securely authenticating computing systems. In some embodiments, a limited use credential is used to provision more permanent credentials. A client receives a limited-use (e.g., a single-use) credential and submits the limited-use credential over a secure link to a server. The server provisions an additional credential (for subsequent authentication) and sends the additional credential to the client over the secure link. In other embodiments, computing systems automatically negotiate authentication methods using an extensible protocol. A mutually deployed authentication method is selected and secure authentication is facilitated with a tunnel key that is used encrypt (and subsequently decrypt) authentication content transferred between a client and a server. The tunnel key is derived from a shared secret (e.g., a session key) and nonces.
