Abstract: Described are techniques for accelerating streaming analytics jobs, which may be used for generating dashboards. The disclosed techniques can reduce overhead, such as in the form of processor usage, network usage, or the like, due to duplicative or overlapping requests for streaming analytics data by implementing a caching process in which analytics data is evaluated to determine if it is likely to be requested multiple times or by multiple users, caching the analytics data, and serving future requests for the same analytics data from the cache instead of requiring separate analytics jobs for each request.

Abstract: Systems and methods for generating digital assets corresponding to physical commodities are provided. Attributes identifying a first physical commodity are used to determine environmental attributes of the first physical commodity. Based on the first physical commodity and the environmental attributes, one or more smart contracts are contacted and activated to generate digital assets. The attributes and an indication of the digital asset are used in conjunction with the smart contract to generate a correlated digital asset, which can be recorded on a digital ledger.

Abstract: An exhaust fan includes a generally square housing, adjustable-height supports, and attachments for a variety of air ducts. The air ducts are each designed to provide a sufficient air seal to effectively enable the exhaust fan to evacuate dust and debris from a wide variety of standard doors or windows, either on the ground floor or an elevated floor.

Abstract: A Multi-I/O SPI for precision converters supports a Dual/Quad/Octal SPI to support the speed requirements for digital transmission and also includes a special mode that can be enabled by hardware and/or software to remove the bit scrambling requirement dictated by the JEDEC standard. The special mode removes the scramble requirement and associates each of the bidirectional data lines to a specific channel. The special mode provides backward compatibility that permits the precision converter to be used with controllers that do not natively support the JEDEC standard. Also, the Multi-I/O SPI includes registers divided into a primary region that is accessed only in default mode at power-up for write and/or read operations, and a secondary region that is accessed by any mode enabled in the control register. By restricting access to the “control” register area to a pre-defined mode in the converter at power-up, the access mode can be controlled.

Abstract: A device for counting particles on a sample surface includes a scanner probe having a first opening for receiving particles from a sample surface and one or more second openings, a particle detector for detecting particles passed there-through, a modulator for modulating air flowing there-through, a pump for producing a first airstream flowing from the first opening and through the particle detector, and for producing a second airstream flowing through the modulator and to the one or more second openings, and control circuitry for controlling the modulator to modulate an amplitude of the second airstream.

Abstract: A particle counting device includes a scanner probe having a first opening for receiving particles from a sample surface and second openings. Pumps produce a first airstream flowing from the first opening and a second airstream flowing to the second openings. A flow device splits the first airstream into third and fourth airstreams. A first particle detector detects particles in the third airstream. The first particle detector is capable of detecting particles within a first range of particle sizes. A second particle detector detects particles in the fourth airstream. The second particle detector is capable of detecting particles within a second range of particle sizes different from the first range of particle sizes. Control circuitry controls the flow device and the pumps to provide a first flow rate of the third airstream and a second flow rate of the fourth airstream that is larger than the first flow rate.

Abstract: The invention concerns a method for cold rolling bright aluminium rolled products and comprises: (a) Providing a first aluminium alloy rolled product (b) Rolling said first product with a rolling mill (1) having at least one work roll ground to a finish (11), with a roughness Ra less than 1 ?m, and using a rolling lubricant (51) from a first container (2) comprising less than 150 mg/L of aluminium debris to obtain a second aluminium rolled product having at least one bright surface, (c) Transferring at least a portion of said rolling lubricant to a second container (3) (d) Filtering the lubricant from said second container (52) by using cross flow filtration (4) through a membrane (41), to obtain a cleaned rolling lubricant (54) comprising less than 10 mg/L and preferably less than 5 mg/L of aluminium debris preferentially having a mean diameter of less than 2 ?m, (e) Returning said cleaned rolling lubricant (54) to the first container.

Abstract: A system and method for managing timely delivery of content is disclosed wherein, to prevent delays caused by pre-delivery processing, such as entitlement or payment processing, the system can initiate delivery of at least a portion of the content. In an aspect, an authorization system can receive a request for content. The authorization system can queue an authorization request and/or an entitlement check for processing in response to the request for content. The authorization system can pre-authorize the request and initiate delivery of at least the portion of content prior to processing the authorization request and/or the entitlement check.

Abstract: Systems and methods for managing data are disclosed. One method can comprise receiving a data request at a first data agent and determining whether the first data agent is configured to satisfy the data request. If the first data agent is configured to satisfy the data request, the data request can be processed via the first data agent. If the data agent is not configured to satisfy the data request, the data request can be transmitted to a second data agent.

Abstract: Methods and apparatus according to the invention are directed towards providing electronic queuing of execution of financial services by a customer of a financial institution prior to the services being performed. Queuing may shift planning of and preparation for execution of the services, away from a time and/or a site of service-execution. Through queuing, the customer may securely produce, access and modify actionable electronic listings of services and of details of service-execution. The customer may securely activate the listings for the performance of service-executions via the institution's associates and/or machines. Queuing may expedite service-execution. The methods and apparatus may also provide for collaboration among customers in producing, accessing, modifying and activating listings.
