Title: Optical amplifier with active-fiber loop mirror
Inventor: ATIEH AHMAD K
IPC: H01S3/083
Filed: 2000-03-24
Abstract: In optical amplifiers of the kind in which a so-called loop mirror is formed by connecting the ends of a loop of active optical fiber to a 3 dB coupler, improved signal-to-noise ratios are obtained by coupling pump energy into the loop without passing through the 3 dB coupler. The input signal and amplified output signal may be conveyed to and from the coupler by way of isolators connected to input and output ports of the amplifier. Alternatively, they may be conveyed by way of a circulator. Automatic gain control may be provided by means of a fiber grating, or other such wavelength-selective device, which reflects part of the amplified signal having a selected wavelength back into the loop, to provide lasing. The amount of energy so reflected may be controlled by an attenuator.

Abstract: Embodiments of the invention provide data structures or objects for use by application behavior analysis tools. The data structures or objects are used to store data pertaining to behavior of an executed application, events, and input and output collected during execution of an application. Consequently, data collected by one application analysis tool may be stored in the data structures. These populated data structures may then be used by other application analysis tools without having to re-execute the application and re-collect the data. Such embodiments reduce the required number of executions of a particular scenario being analyzed. Additionally, data collected and stored in the common data structures during a single execution may be analyzed in various ways by suitable analysis tools available. This may enable defects which are not identifiable using a particular analysis tool from a first vendor to be identified using a different analysis tool from a second vendor without the need to re-run or re-execute the scenario.

Abstract: The invention relates to a yarn feeder (1) which comprises a yarn feeding wheel which is preferably made of a ceramic material or coated with an equivalent substance. Owing to the materials used and/or its shape the yarn feeding wheel presents improved continuous service properties. Said shape and/or material are highly wear-resistant. This is achieved by ceramic surfaces and/or the combination of a conical, continuous yarn inlet surface (24) with strip-shaped support surfaces (25) contiguous thereto in the yarn storage area (26), and a continuous, i.e. uninterrupted, surface in the yarn  outlet area. The surfaces are configured such that on its way from the inlet  area to the outlet area the yarn moves across the corresponding surfaces (24 , 25, 36) along its entire axial path. The strip-shaped bearing or support surface for the yarn (2) in the yarn storage area is obtained by shaping the  yarn feeding wheel (17) accordingly in said yarn storage area. Openings or slits or such like in the yarn feeding wheel are not required but can be provided for.
Patent CA-2345893-A1 (CA)
Title: Spin weld assembly
Inventor: GOSS DAVID C
IPC: B29C65/08
Filed: 2001-05-01
Abstract: The present invention provides novel structures for spin weld assemblies and a method for forming same. The spin weld assemblies are formed by attaching a fastener to a plastic insert which is then attached to a plastic workpiece. The fastener can take the form of many different structures, preferably a stud or a nut. The fastener is formed with a drive for driving the fastener into a bore of the plastic insert having first and second ends. Self-tapping threads on the fastener engage the fastener with the plastic insert when the fastener is driven into the bore of the insert. The insert, having the fastener threadedly engaged thereto, is then rotated and generally axially displaced into an opening of the plastic workpiece, thereby spin welding the insert to the workpiece. The first end of the insert provides proper alignment for the insert to be spin welded into the opening as the diameter of the first end is smaller than that of the opening. The second end of the insert provides the intimate engaging contact between the insert and a wall that defines the opening when the insert is spin welded into the opening as the diameter of the second end is larger than the diameter of the opening.
