摘要:
A sensing means comprises four uniaxial sensors each capable of detecting a movement component along a respective axis having a respective orientation and arranged such that the angles between any two of said respective orientations of said respective axes are substantially equal, wherein the uniaxial sensors are arranged such that in use the respective axes are at substantially the same angle to the vertical.

The present invention provides an emerging security or authentication feature for objects (e.g., identification documents, product packaging, banknotes, etc.). One method recites: exciting an object with a first non-visible light, the object comprising first indicia provided with a first ink or dye and second indicia provided with a second ink or dye, the second ink or dye comprising an emission decay time that is relatively longer than an emission decay time of the first ink or dye, the first indicia and the second indicia collectively conveying a first machine readable feature when illuminated with the first non-visible light, with the second indicia individually conveying a second machine readable feature after emissions attributable to the first indicia fall to a first level; and machine detecting at least the second machine readable feature after emissions attributable to the first ink or dye fall to the first level and before emissions attributable to the second ink or dye fall to a second level. Other combinations are provided as well.
摘要:
A spinal stabilization system may be formed in a patients. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. The collar may be rotated and/or angulated relative to the bone fastener. Detachable members may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The detachable members may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars.
摘要:
In some embodiments, a system may reduce contaminants in water. A system may include a biofilm in a container. The biofilm may be formed from one or more bacteria coupled to one or more substrates. The bacteria may be selected to maximize the reduction of contaminants in water. The system may include one or more bacteria generators to provide bacteria to the biofilm and/or one or more air sources to provide an air bubble stream to the container and/or the bacteria generator. In some embodiments, bacteria may be preserved in a starvation phase. Bacteria may be incubated until they reach a starvation phase. The bacteria may then be preserved as beads or immobilized on a substrate. The preserved bacteria may be used in a system for the reduction of contaminants in water.

The present invention teaches an easy to make and low cost lemon ice dessert and a method of making by carefully controlling boiling times and temperatures so as to maintain a natural lemon savor in a straightforward combination of sugar, lemon product and water. The mixture of lemon extracted fluids, sugar and water provides an all-natural frozen ice confection of unusual consistency and flavor with easy manufacture.
摘要:
In one embodiment, a method for manufacturing an identification document is provided. The method includes: providing a substrate constructed and arranged to receive printing thereon; printing a first variable indicium on the substrate, where the first variable indicium is not visible to the human eye in ambient light but is visible to the human eye when viewed using a first type of light; and printing a second variable indicium on the substrate, the second variable indicium being visible when viewed using ambient light. Other methods, systems and documents are provided as well.
