Abstract: Fluidic devices and methods associated with mixing of fluids in fluidic devices are provided. In some embodiments, a method may involve the mixing of two or more fluids in a channel segment of a fluidic device. The fluids may be in the form of, for example, at least first, second and third fluid plugs, composed of first, second, and third fluids, respectively. The second fluid may be immiscible with the first and third fluids. In certain embodiments, the fluid plugs may be flowed in series in the channel segment, e.g., in linear order, causing the first and third fluids to mix without the use of active components such as mixers. The mixing of fluids in a channel segment as described herein may allow for improved performance and simplification in the design and operations of fluidic devices that rely on mixing of fluids.

Abstract: The disclosure is directed to storing data in different tiers of a database based on the access pattern of the data. Immutable data, e.g., data that does not change or changes less often than a specified threshold, is stored in a first storage tier of the database, and mutable data, e.g., data that changes more often than immutable data, is stored in a second storage tier of the database. The second storage tier of the database is more performant than the first storage tier, e.g., the second storage tier has a higher write endurance and a lower write latency than the first storage tier. All writes to the database are performed at the second storage tier and reads on both storage tiers. The storage tiers are synchronized, e.g., the set of data is copied from the second to the first storage tier based on a trigger, e.g., a specified schedule.

Abstract: Storing data in a cache is disclosed. It is determined that a data record is not stored in a cache. A random value is generated using a threshold value. It is determined whether to store the data record in the cache based at least in part on the generated random value.

Abstract: A solid state lighting apparatus can include a variable color input signal configured to indicate a target color of light output from the apparatus. A string current Pulse Width Modulation (PWM) controller circuit can be coupled to the variable color input signal, where the string current PWM controller circuit can be configured to generate a plurality of PWM signals having respective variable duty cycles to enable/disable respective particular string currents for respective variable times as the variable color input signal changes.

Abstract: Solid state fixtures and packages are disclosed that include an optical element, such as an encapsulant, having an integrated indicator which indicates one or more characteristics of the package to a user, such as package orientation, polarity, chip-type, etc. The host optical element can be substantially symmetrical but for the indicator. Indicators can be additive, such as a bump, or subtractive, such as a hole. The indicator can be visible to the human eye, and/or can be machine detectable, such as by pick-and-place technology. Indicators can be formed by many processes including molding and laser ablation/imprinting, which is particularly suited for use with a hard host material.

Abstract: Techniques for content services are provided. Documents are managed from their native storage locations. Access to portions of the documents is provided via separate addressable references. Principals access and annotate the portions of the documents remotely. Identity and policy restrictions are enforced against access from the native storage locations.

Abstract: The present invention teaches a purchase enabling database consisting of customer records which each contain 1) sufficient commercial information about a customer to enable an electronic purchase and 2) a face key of electronic facial recognition identity data allowing electronic comparison to a submitted facial identity code candidate. If the facial recognition of the candidate face indicates a match, the individual is able to make a commercial transaction without further exchange of financial information, thus allowing the user/customer to make a purchase. A system embodiment allows a subscribing vendor to embed facekey enablement in their own vending website/software/hardware.

Abstract: A method and device for purchase transactions to be consummated within a media player teaches that a media player may offer a virtual shopping cart and the ability to accept financial information such as credit card information in order to complete an entire sale within the confines of an advertisement for a product. In embodiments the player may have a virtual shopping cart module and a financial transaction module and may be offered as a service to sellers by a third party intermediary advertiser which plays the advertisements, handles purchases through the player and then places the order with the seller and confirms the purchase with the buyer.

Abstract: A voice checkout system and method for electronic commerce uses a webpage module to activate a customer's microphone. A recording of a verbal identity code candidate is submitted by a portal to a biometric voiceprint engine which identifies the correct words and vocal patterns of the customer and returns to the seller the information that the transaction is verified. The system includes security features to verify that recording is not used, that the words of the voiceprint are not being spoken by a different party and so on.

Abstract: The present invention relates to isolated Chaperonin 10 polypeptides possessing immunomodulatory activity, but lacking, or substantially lacking, protein folding activity.

Abstract: A system and method facilitating online purchases within social network environments comprises posting or re-posting a string of characters affiliated with a product on a social network newsfeed, page, or as a status update. The system includes a search engine monitoring posts for the string of characters indicating intention to purchase and a payment processing component. The purchase is completed without further entry of information by the user if the user's financial data is previously available. The system may include a customer validator, payment information validator, electronic receipt generator, error detection components, and may communicate with an external merchant account. The method allows an internet merchant or marketer to offer a product for sale by posting a string of characters that can be purchased by users of a common social networking platform by posting or re-posting the string of characters.

Abstract: A method of operating a data transport system on a computing device is disclosed. The method comprises: writing outgoing data in a first memory space on a memory module of a computing device; detecting the outgoing data on the first memory space by a data channel component coupled to the memory module, wherein the first memory space is designated for external data transmission; and generating a transmission signal encoding the outgoing data, via the data channel component, for transmission from the memory module through an inter-device interconnect to an external memory module.

Abstract: A system and method are provided for encouraging online shoppers to share online purchase transactions. Included are online advertisements or offers at the point of checkout. These offers indicate an incentive for sharing information about the online purchase on one or more social network platforms of the online shopper. The system may also include a pre-made or subsequently created video component featuring the product or a statement or opinion about the product. When the online shopper indicates a willingness to share in order to receive the incentive the video component featuring the product or a link thereto is displayed on the online shopper's social network platform as a posting in a newsfeed, on a profile page, or as a status update for the social network connections of the online shopper to see. The social network connections can then purchase, share, redeem and offer incentives as well.

Abstract: The specification generally discloses systems and methods for mixing and delivering fluids in microfluidic systems. The fluids can contain, in some embodiments reagents that can participate in one or more chemical or biological reactions. Some embodiments relate to systems and methods employing one or more vent valves to controllably flow and/or mix portions of fluid within the microfluidic system. Advantageously, fluid control such as a sequence of fluid flow and/or a change in flow rate, can be achieved by opening and closing one or more vent valves and by applying a single source of fluid flow (e.g., a vacuum) operated at a substantially constant pressure. This can simplify the operation and use of the device by an intended user.
