Abstract: An optical device, preferably a security device for a security document, including: a transparent or translucent substrate having a first side and a second side; a first depiction layer located on the first side of the substrate defining a first depiction; and a first masking layer, comprising a first optically variable ink, and a second masking layer, comprising an optically variable ink, located at least partially overlapping the first depiction layer, wherein the first depiction is at least substantially opaque and has a low contrast with respect to the appearance of the first and second masking layers when viewed in reflection, such that the first depiction is identifiable and substantially more visible when viewed in transmission than when viewed in reflection, and method for the manufacture thereof.

Abstract: An automated small particle distribution system is provided for transferring small particles from source tubes to destination tubes. The system includes a loading deck that is structured and operable to store and provide a plurality of source tube trays and a plurality of destination tube trays. Each source tube tray includes a plurality of source tubes stored therein, and each destination tube tray includes a plurality of destination tubes stored therein. The system additionally includes a work deck is structured and operable to receive selected source tube trays and selected destination tube trays from the loading deck, aspirate various specified amounts of small objects stored in selected source tubes, and deposit the aspirated small objects into selected destination tubes without cross-contamination of small objects.

Abstract: Computer-implemented methods and systems include proxying a request for a web page from a web server; generating a request for content from one of a plurality of downstream applications corresponding to the request; transmitting the request to the one of the plurality of downstream applications; receiving a response from the one of the plurality of downstream applications, the response including the content; decorating the content to generate a decorated web page; and transmitting the decorated web page to the web server.

Abstract: Hydroponic apparatus and methods for the high-throughput screening plants are disclosed. In one aspect, a method for the high-throughput screening of plants is disclosed.

Abstract: An architectural stack includes a multivariate testing system between the web server and the HTTP proxy cache. The multivariate testing system receives a user request to access a web page from the web server, applies a rule to the user request to assign the user to a test group, each test group associated with a different page version for testing, and delivers a web page or web site version to the user based on the user's assigned test group. The user's interactions with the delivered web page and subsequent behavior are then tracked or recorded and aggregated with all of the other users and other test groups. The aggregated data can then be analyzed to determine a test result.
