The instant application provides a method for running an organization. Each individual in the organization is assigned to one of a plurality of circles. The circles uses dynamic steering in the performance of periodic governance meetings. The governance meetings are used to: define accountabilities, in which each accountability is an activity performed in service of the organization; define roles; assign to each role at least one of the accountabilities; assign to each individual in the circle at least one of the roles, wherein each individual filling a role is accountable to the organization for every accountability assigned to that role; and using a decision-making process to resolve identified tensions within the circle. Additionally, the circles use dynamic steering in the performance of periodic operational meetings. The operational meetings are used to: exchange information and make decisions requiring integration of multiple roles in the circle; review metrics relevant to the circle; and resolve tactical issues related to the circle.

The present invention comprises a removable cover plate assembly, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The cover plate assembly improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. Moreover, the cover plate assembly of the present invention enables a single set of concave grate assemblies to better harvest a wider variety of crop types.

This invention relates to methods and apparatus for routing light beams in telecommunications devices using holographic techniques, in particular by displaying kinoforms on LCOS (Liquid Crystal on Silicon) devices. Thus we describe optical beam routing apparatus comprising: at least one optical input to receive an input beam; a plurality of optical outputs; a spatial light modulator (SLM) on an optical path between said optical input and said optical outputs; and a driver for said SLM to display a kinoform on said SLM to diffract said input beam into an output beam comprising a plurality of diffraction orders, wherein a routed one of said diffraction orders is directed to at least one selected said optical output; wherein said apparatus is configured to modify a wavefront of said output beam to reduce a coupling of said output beam into said selected optical output; and wherein said kinoform is adapted to compensate for said wavefront modification to compensate for said reduced coupling and thereby to reduce a coupling of other diffracted light from said input beam into others of said optical outputs than said at least one selected optical output.

摘要:
An optical switch uses two ferroelectric liquid crystal spatial light modulators (10, 11) with an interconnect region in between. The switch uses bulk lenses (2, 8) to focus light from an input fibre array (1) to a first spatial light modulator (10), and from the second spatial light modulator (11) to an output array (9). Each spatial light modulator displays a respective hologram selected from a previously calculated set, to cause a desired switching of light from the input fibre array to the output array.

An optical interconnection arrangement comprises a plurality of substantially parallel optical interconnection channels. In each channel, there are an optical source, an optical receiver, a first lens and a second lens. The first lens conveys light from the source to the second lens, and the second lens refocusses the light at the receiver. Each source and the associated first lens are offset one relative to the other by a predetermined distance in a direction transverse to an optical axis of the first lens. The corresponding receiver and the associated second lens are offset one relative to the other by the same distance but in the opposite direction to the offset between the source and first lens. Each offset is equal and opposite to the corresponding offset in an adjacent channel. With such an arrangement, if a leakage portion of a light beam from a first lens in one channel impinges upon the second lens in an adjacent channel, the leakage portion will be refocussed at a position which is spaced from the receiver of such adjacent channel. In one embodiment, in each channel, the first lens and the second lens share a common optical axis and the source and receiver are offset relative to such common optical axis. In an alternative embodiment, the source and the receiver share a common optical axis and the first lens and the second lens are offset relative to such common optical axis. Such optical interconnection arrangements are tolerant of translational or rotational misalignments between the sources and associated first lenses on the one hand and the receivers and associated second lenses on the other hand, which is of particular advantage for free space optical interconnects or couplers.

A method for increasing the strength of a solder joint between a nickel-iron lead frame of an electronic circuit module and a copper pad of a printed circuit board on which the module is mounted includes baking the joint for at least one hour at a temperature in the range 373K to 456K. The baking step is found to significantly increase the strength of the joint.
