  • Publication number: 20170094019
    Abstract: A computer-implemented technique enables a creator-user to create an obscured version of a content item. The technique then posts the obscured version to a hosting environment. A monitoring system receives a requestor-user's request to obtain a non-obscured version of the content item. In response, the monitoring system determines whether a number of requestor-users who have made such a valid request exceeds a predetermined threshold value set by the creator-user. If so, the monitoring system provides access to at least part of the non-obscured version of the content item to all requestor-users who have made valid requests.

  • Publication number: 20080031226
    Abstract: A multiplicity of users is connected to a network, as are m servers. The users are organized into n user groups, each including a plurality of users, such that all the users in a group are part of a common database which permits intercommunication between them. That database is duplicated in a subset of p of the servers, and the subset shares the processing load of the corresponding user group. When a user in the respective user group attempts to communicate with another user, one of the servers in the subset p will accommodate the necessary processing initiate set up of the connection. At the same time, each server accommodates users in q different groups. Should one of the servers fail, each of the other servers in each subset p accommodating the failing server's users will accommodate the failed server's share of those users. Thus, the processing load of each user group is handled with a redundancy of p (the number of servers in a subset), ensuring a high level of availability.

  • Patent number: 7275821
    Abstract: A spectacles includes two lenses, a spectacles frame and an adjustment hinge arrangement. The spectacles frame includes two supporting arms and a bridge extending between the two supporting arms. The adjustment hinge arrangement pivotally couples the two lenses with the two supporting arms respectively to pivotally fold the two lenses between an idle position and an usage position, wherein at the idle position, the two lenses are upwardly and pivotally flipped to move away from the bridge, and at the usage position, the two lenses are downwardly and pivotally flipped at a position that the bridge is positioned between the two lenses.

  • Patent number: 7144709
    Abstract: A reagent is suitable for measuring the concentration of an analyte in a hemoglobin-containing biological fluid, such as whole blood. The reagent comprises a flavin-dependent enzyme that has specificity for the analyte, a flavin cofactor if, and only if, a flavin is not bound to the enzyme, a tetrazolium dye precursor, an electron transfer agent, and a nitrite salt. The reagent causes dye formation that is a measure of the analyte concentration. The nitrite salt suppresses interfering dye formation caused non-enzymatically by the hemoglobin. Preferably, the reagent is used in a dry strip for measuring glucose in whole blood.

  • Patent number: 6884592
    Abstract: Test strips for determining the concentration of at least one analyte, e.g., glucose, in a physiological sample and methods for their manufacture and use and are provided. The subject test strips include a transfer element for facilitating the transfer of sample to a reaction area of the test strip. In certain embodiments, the transfer element, typically porous, has a first area and a second area, and in certain embodiments the two areas have different thicknesses. In other embodiments, the transfer element is non-porous and is configured to transfer sample by wicking it between the transfer element and the reaction area of the test strip. In the subject methods, the transport element facilitates transfers of a sample to a reaction area of the test strip. The subject test strips and methods find use in a variety of different applications, particularly in the determination of glucose concentrations.
