Inventor: FITCH MARK A
IPC: G02B6/255
Filed: 2000-11-27
Abstract: A method is provided for fusion-splicing with a laser beam (10) at least two optical components (14a, 14b) to a different optical component (16), the different optical component (e.g., an optical element (16) such as a lens) having a surface that has a comparatively larger cross-sectional area than a surface of the other optical components (e.g., at least two optical fibers (14a, 14b)). The method comprises: a) aligning the optical components (14a, 14b, 16) along an axis; b) turning on a directional laser heat source to form the laser beam (10); c) directing the laser beam (10) to be collinear with those optical components (14a, 14b) having a smaller cross-sectional area; d) ensuring that the laser beam (10) strikes the surface of the optical component (16) having the larger cross-sectional area at normal or near normal incidence so that absorption of the laser beam (10) is much more efficient on the surface; e) adjusting the power level of the laser beam (10) to reach a temperature equal to or higher than the softening temperature of the surface of the optical component (16) having the larger cross-sectional area to form a softening region thereon, thereby achieving the fusion-splicing; and f) turning off the laser.

Title: Systems and methods for detecting imperfect connections in optical systems
Inventor: STUMMER ALAN D
IPC: H04B10/08
Filed: 2001-01-12
Abstract: A system prevents damage to at least one component of a laser apparatus that  includes a laser that emits a light signal of increasing power during power up and at least one connector that receives the light signal from the laser and  reflects at least a portion of the light signal when an imperfect connection  exists. The system includes a detector and a monitoring circuit. The detecto r detect the reflected light signal from the connector. The monitoring circuit  receives the reflected light signal, determines an amount of power in the reflected light signal, calculates a ratio of the power of the light signal emitted by the laser to the power in the reflected light signal, compares th e ratio to a predetermined threshold to determine whether the imperfect connection exists, and shuts down the laser when the imperfect connection exists.

Inventor: CUNDALL JOHN
IPC: G06F21/12
Filed: 2000-02-16
Abstract: According to the present invention there is provided a method for downloading software from a mobile network operator to a mobile phone user. The downloaded software can be new network services or user specified applications software or user specified information. The method requires the downloaded software to written as Java classes capable of running on a Java Virtual Machine. All the Java classes can be continuously broadcast at a relatively modest data rate. In an enhanced mode a list of services available for downloading is broadcast over the network more frequently then the actual services themselves. The user then selects which service he wants and only that one is downloaded. Payment can be on a subscription or pay-per-use basis. The method could also be adapted to work with one of the new digital broadcasting platforms such as DAB or DVB as a means for delivering the Java classes. This would significantly increase the volume of data which could be downloaded thus increasing the number of new services or information which could be accessed.

Abstract: Control section determines necessary acceleration of a transporting section in accordance with an actual transporting speed, and also determines a correction coefficient corresponding to the number of rotations of an engine from among correction coefficients having a characteristic of becoming closer to a value of one as the number of rotations of the engine increases. The control section multiplies the necessary acceleration by the correction coefficient to thereby provide corrected necessary acceleration, and controls rotation of a transporting drive motor in accordance with the corrected necessary acceleration. When the amount of electric power to be generated by a power generator driven by the engine has increased, the control section controls the opening of a throttle valve.

Title: Multi-level stacking/nesting tray
Inventor: STAHL EDWARD L
IPC: B65D21/04
Filed: 2001-05-09
Abstract: A novel container (20) for transport or storage of products such as bread, buns, or other goods. In one embodiment, there is provided a nestable container with a base (24) and sidewalls (28, 32) that can be stacked in two positions for different products and can be nested when empty for compact storage. The container has levered positions for lifting out of each stacking position and into a corresponding sliding position. The sliding positions can be used to offset the container or containers from the stack and reduce the strain on the operator when lifting for destacking. Alternatively, the container can slide in the opposite direction for stacking in either position.  Thus the operator can set the container down, offset from the stack, in the sliding position and slide into stacking position. Back strain can be reduced during stacking and destacking as the operator does not have to extend or lean over the stack to pick up or set down the containers.

Title: Rotating arc fault-current interrupter
Inventor: ZEITLER MARTIN JR
IPC: H01H1/58
Filed: 2002-10-17
Abstract: A rotating arc fault-current interrupter, also known as an arc spinner interrupter, is provided that establishes an easily visible open gap via a movable blade member having a first portion for engaging a stationary main contact and a second portion formed by an arcing electrode for engaging an auxiliary contact associated with an arc spinner assembly. The geometry, orientation and placement of the auxiliary contact is such that during opening of the movable blade member, the arcing electrode remains engaged with the auxiliary contact after the blade member and the stationary main contact are separated from each other whereby current is transferred through the auxiliary contact into the arc spinner assembly, i.e. the current is commutated into the arc spinner assembly. Thus, the current in the arc spinner creates a magnetic field to cause the arcing current to rotate rapidly so as to extinguish the arc as the arcing electrode separates from the auxiliary contact and moves to the opened position whereby a visible open gap is established that is easily visible without any obstructions from a range of viewing angles or orientations.
