  • Patent number: 9827311
    Abstract: The present invention relates more specifically to a cosmetic treatment method intended in particular to improve the appearance of the skin and/or hair comprising the simultaneous and/or sequential administration: a) of at least one cytochrome C oxidase substrate and/or of at least one agent which increases the expression of the said substrate; and b) of at least one light radiation exhibiting at least one predominant wavelength which activates cytochrome C oxidase. In particular, the said light radiation exhibits at least one predominant wavelength which activates cytochrome C oxidase ranging from 550 to 1000 nm, in particular from 550 to 800 nm, preferably from 620 to 700 nm and more preferably still from 640 to 680 nm and is preferably used at a dose ranging from 0.01 to 200 J/cm2, preferably from 0.1 to 30 J/cm2, more preferably from 1 to 30 J/cm2, indeed even from 5 to 30 J/cm2.

  • Patent number: 9768962
    Abstract: The subject disclosure is directed towards credential verification for accessing a service provider. A user may prove to the service provider the validity of the credential by communicating a non-revocation component that is based upon a prime-order cryptographic group without a bilinear pairing. In order to authenticate the user, a verification mechanism within an identity management system applies private cryptographic data, including a verifier-designated private key to the non-revocation component, which proves that the user's identity and therefore, the credential is not revoked. The presentation proof includes a hash value that is computed using the credential's commitment and the prime-order cryptographic group. By verifying that the hash value was computed using that commitment, the verification mechanism validates the credential and permits access to the service provider.

  • Patent number: 9750675
    Abstract: The present invention relates to the use of a source of green light for activating L-amino acid oxidase in the presence of at least one substrate of this enzyme in order to stimulate the energy metabolism of the cells of the skin, to stimulate their replacement and thus to improve the appearance of the skin and hair, in particular to prevent and/or treat cutaneous signs of ageing of the skin and hair.

  • Patent number: 9722776
    Abstract: The subject disclosure is directed towards a technology by which data is securely distributed using a homomorphic signature scheme and homomorphic network coding signature schemes. A homomorphic signature scheme for signing the data is based upon binary pairing with standard prime order groups. Sets of data are signed based upon dividing a larger block of data into smaller blocks, and separately signing each smaller block. The smaller blocks may be distributed to nodes of a network topology that are configured for network coding. In one alternative, the homomorphic signature scheme protects against changes to the block identifier. Proof data may be provided independent of a random oracle, may be provided by providing parameters for verification in a Groth-Sahai proof system, or may be provided by providing parameters for verification independent of a Groth-Sahai proof system.

  • Publication number: 20160328849
    Abstract: An automated method for detecting circulating tumor cells in a microscopic image of a blood sample includes receiving, by a computer, a plurality of low-resolution images, each low resolution image providing a representation of the blood sample with one of a plurality of stains applied. The computer determines a threshold value for each of the plurality of stains based on the low resolution images and identifies a list of potential cells based on the threshold values. A gating process is performed on the list of potential circulating tumor cells to identify one or more likely or highly likely circulating tumor cells. The computer presents the subset of the low-resolution images in a verification interface comprising one or more components allowing a user to confirm that a respective low-resolution image included in the subset of the low-resolution images includes one or more circulating tumor cells.

  • Publication number: 20160241547
    Abstract: The subject disclosure is directed towards processing requests for accessing a service provider. After examining at least one security token, a public key and a portion of attribute information are identified. An authentication component is accessed and applied to the public key. A unique user identifier is employed in generating the public key. The authentication component is generated using information from at least one revoked security token or at least one valid security token. The authentication component is configured to prove validity of the at least one security token.

  • Patent number: 8839381
    Abstract: The claimed subject matter provides a method for revoking delegatable anonymous credentials. The method includes receiving a request to revoke an anonymous credential. The anonymous credential may be representative of an ability to prove non-membership in an accumulator for a first entity. The method also includes revoking the anonymous credential from the first entity in response to the request to revoke the anonymous credential. Additionally, the method includes revoking the anonymous credential from a second entity in response to the request to revoke the anonymous credential. The first entity delegates the anonymous credential to the second entity.

  • Publication number: 20130233394
    Abstract: Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight and whether the container weight is below a pre-established threshold, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.

  • Patent number: 8325924
    Abstract: In an example, one or more cryptographic keys may be associated with a group. Any member of the group may use the key to encrypt and decrypt information, thereby allowing members of the group to share encrypted information. Domain controllers (DCs) maintain copies of the group's keys. The DCs may synchronize with each other, so that each DC may have a copy of the group's keys. Keys may have expiration dates, and any client connected to a DC may generate a new key when a key is nearing expiration. The various clients may create new keys at differing amounts of time before expiration on various DCs. DCs that store keys early thus may have time to propagate the newly-created keys through synchronization before other DCs are requested to store keys created by other clients. In this way, the creation of an excessive number of new keys may be avoided.
