A light-emitting device (10) using an LED is proposed. This light-emitting device (10) is provided with a packaging substrate (1), a light-emitting element (2) which is mounted on this packaging substrate (1) with its face down, a fluorescent member (3) that is arranged face to face with a light-extracting surface (S) of the light-emitting element (2) without contacting the light-emitting element (2) and an optical member (4) which receives light that has been emitted from the light-emitting element (2) and made incident thereon through the fluorescent member (3), and aligns the incident light toward the outside of the device. Light, emitted from the light-emitting element (2), is made incident on the fluorescent member (3) to excite the fluorescent material so that the fluorescent material re-emits light having a wavelength different from that of the incident light. Those light rays, emitted from the light-emitting element (2), which have not been absorbed by the fluorescent member (3) and have passed through the fluorescent member (3) and those light rays that have been emitted from the fluorescent material are made incident on the optical member (4) and are aligned. Because the fluorescent member (3) is not made in contact with the light-emitting element (2), it does not receive the heat from the light-emitting element (2) through heat conduction, and consequently becomes less susceptible to degradation due to heat. Moreover, with the face-down mounting structure, the fluorescent member (3) and the optical member (4) can be placed closer to the light-emitting element (2) as long as they dose not contact the light-emitting element (2). Consequently, the service life of the fluorescent material or the fluorescent-material-mixed resin that tends to deteriorate can be lengthened, lights can be extracted more efficiently, and light rays can be properly aligned in a predetermined direction.

System and method of determining active / standby statuses of an intermediary device with respect to a logic group based on a user defined switchover policy. A user is allowed to configure a template to determine respective health levels for multiple sets of delivery resources. Each set of resources associated with a function engine residing in a respective intermediary device. The multiple sets of resources, in conjunction with the associated function engines, are equivalently operable to provide the same service function. The template may include user-specified events and respective weight factors. The specified events are monitored and a health score is dynamically derived for each delivery resource based on the template. Based on an updated health score rank with respect to the service function, a switchover may automatically occur from an intermediary device of a lower health score to another device with a higher health score.

A quick insertion fastener has an internally threaded first member ("nut") adapted to be quickly attached and tightened on an externally threaded second member ("bolt"). The nut is formed with a casing with an internal frusto-conical front surface, a plurality of threaded shell segments contained in the casing having external frusto-conical front surfaces which abut the front surface of the casing, a spring member positioned at a rear part of the casing which elastically holds the rear ends of the shell assembly together, and an end retainer provided at the rear part of the casing having a taper for engaging the rear ends of the shell assembly and displacing them radially apart when the shell assembly is displaced axially toward the end retainer by insertion of the bolt. This allows the bolt threads to move without interference past the internal threads of the shell segments. When the insertion force of the bolt is released, the spring member urges the shell segments together so that the internal threads of the shell assembly become engaged with the bolt, and the nut can be tightened on the bolt. The spring member may be a radial spring or O-ring, or in the alternatively may be a wave compression spring, segmented spring, circumferential or axial leaf springs, or a flexure spring formed integrally with the end retainer. The nut may also be configured with an external sleeve member for pulling the shell assembly back relative to the nut casing for quick disengagement from the fastener.

Disclosed are a method, system, program and data structure for implementing a records retention policy by storing selected files for designated lengths of time and then deleting them only when that time has passed. Embodiments of the invention perform this function in an efficient database-free manner. Embodiments of the invention can perform this function by utilizing existing storage directory tree functionality provided by any computer operating system organized under a retention directory coupled with a mechanism for preventing unauthorized deletions of files designated for retention. Expiration of retained files may be managed through directory structure using directory names corresponding to expiration dates determined from identified retention periods for retained files. Files may be further protected from erasure by a kernel mode process which prevents erasure of any files contained in the retention directory.

A data file or data record is operated on in order to transform the data record by user actions. A history record of actions is accumulated. Various operations are performed on selected actions of the history record to modify the sequence of actions of the history record. Preferably the changed history record actions are applied to the data record to produce desired results.

Embodiments described herein provide a more flexible, effective, and computationally efficient means for determining multiple intents within a natural language input. Some methods rely on specifically trained machine learning classifiers to determine multiple intents within a natural language input. These classifiers require a large amount of labelled training data in order to work effectively, and are generally only applicable to determining specific types of intents (e.g., a specifically selected set of potential inputs). In contrast, the embodiments described herein avoid the use of specifically trained classifiers by determining inferred clauses from a semantic graph of the input. This allows the methods described herein to function more efficiently and over a wider variety of potential inputs.
