摘要:
A laser system and interferometer are disclosed comprising a laser source for generating a laser beam, and first and second adjustable elements wherein the first and second adjustable elements have limited rotational motion so rotation of the first adjustable element causes deviation of a laser beam in one plane and rotation of the second adjustable element causes deviation in a second plane, and a laser beam from the laser source is oblique to a required beam direction whereby rotation of the adjustable elements deviates the laser beam enabling alignment of the laser beam to the required beam direction. The adjustable elements may be rotatable through 90°. The first and second planes may be perpendicular to the required beam direction and to each other. At least one mirror may be provided which can be angularly offset to the required beam direction.

A laser interferometer is disclosed comprising a housing capable of being substantially repeatably mounted to a wall of an environmental chamber, the housing including a laser source, a reflector attached to an object located within the environmental chamber, and a light passage provided through the wall of the environmental chamber enabling passage of a laser beam from the laser source to the reflector. At least one beam steerer may be provided for adjusting direction of passage of a laser beam through the light passage. Also disclosed is a column laser interferometer.

A system is provided for mechanically keying a number of cable connectors using a binary coding system to assure within a given set of cables that only one, unique matching set is defined. Binary keying is provided using 2×n holes aligned on each face of opposing key mounting surfaces, the holes aligned such that when a post is secured in a hole on one of such mounting surfaces, it will be received by a matching hole in the opposing mounting surface, provided said opposing mounting surface has been complimentarily keyed. The holes are arranged as bit pairs whereby each hole of the bit pair is assigned as the “0” and “1” position, the bit designated as either “0” or “1” depending into which of the paired holes a keying post is placed. By this system up to 2n uniquely keyed combinations can be provided.

摘要:
Methods for the analysis of receptor-ligand pairs are herein described. The methods can provide information about the binding affinity of a ligand to a receptor or can provide information about the binding kinetics of a ligand to a receptor. In some instances, the methods provide a very general system for evaluating and/or optimizing receptor-ligand interactions, which can be applied to a variety of types of receptor-ligand interactions, for example protein-small molecule interactions.

A ventilated padded material suitable for providing air circulation in padded lingerie is disclosed. Padded lingerie, for example, bras, typically are made from man-made materials that prevent perspiration from evaporating and then accumulates in the breast cup area. The retained perspiration causes discomfort to the wearer, as the surrounding breast area remains moist and damp. The ventilation channels or perforations in the padding material, in accordance with the principles of the present invention, enable air circulation to occur through the padding material. Increased air circulation through the padding material allows for perspiration evaporation and less accumulated perspiration.
摘要:
A foldable model made out of a number of wire materials through deformation, assembling and welding to form a main body portion and several accessory portions, characterized in that the joining of the accessory portions with the main body portion are carried out by means of hinges and pivotal fastening latches so that those portions needing to be folded can be folded into or towards said main body portion to reduce the overall packing dimension of said model. The foldable animal model according to the present invention after being folded occupies a volume much smaller than that of a prior art animal model of corresponding dimension after being dismantled and the folding process before packing and the unfolding process after transportation are very simple and easy. Therefore, the foldable model of the present invention is not only convenient for transportation but also the relevant cost thereof have evidently been reduced, so that the selling prices of various models can thus be reduced.
