Abstract: Systems, methods, and computer-readable storage media providing highly scalable and fault tolerant notification systems are disclosed. Disclosed notification systems may be configured to: receive a plurality of notification requests including message content and recipient information, which may be allocated to at least one notification engine for processing. A notification engine may be configured to: generate a plurality of attempts corresponding to notification requests allocated for processing by the first notification engine and assign each generated attempt to a particular attempt queue. A plurality of connectors may be configured to: select a set of attempts for transmission from the plurality of attempt queues, transmit the set of attempts via at least one communication network. One or more databases may be provided to store status information associated with processing of notification requests by the first notification engine.

Abstract: Systems, methods, and computer-readable storage media for providing a notification system are disclosed. The notification system may be configured to select one or more notification requests from each of a plurality of notification request queues, and generate a plurality of attempts for each of the one or more selected notification requests. The attempts may be assigned to one of a first plurality of attempt queues, and flow control logic may be executed against the first plurality of attempt queues to dynamically select attempts for transmission from among the first plurality of attempt queues. Selected attempts are inserted into one of a second plurality of attempt queues, and a plurality of connectors may be configured to select attempts from the second plurality of attempts queues for transmission via a communication channel.

Abstract: A common tray for HGA comprises a frame, a first inner bar, and a second inner bar parallel to and spaced from the first inner bar. Ends of the first and second inner bars connect to the opposite edges of the frame. A plurality of locating pillars and a plurality pairs of first bumps are uniformly-spaced formed on the first inner bar respectively. The first inner bar has portions between each said pair of first bumps recessed for forming spaces under the HGA. A plurality of second bumps are uniformly-spaced formed on the second inner bar for withstanding an edge of the base plate. The present common tray can replace five kinds of trays traditionally used in the HGA manufacturing process, and thus reduce the load/unload operations as well as the no-value stations and operators, thereby the productive efficiency is improved, and manufacturing cost is reduced.
