摘要： Multi-domain liquid crystal cells having twist angles less than 90 degrees, and LCDs containing such liquid crystal cells, are provided. Such liquid crystal cells are stable, particularly at zero and high fields, and provide wide viewing angles. Also provided are methods of using an adjustable particle beam in combination with a mask to generate multi-domains alignments. Such methods are useful for producing liquid crystal cells in general, and for producing the novel multi-domain low twist angle liquid crystal cells of the present invention in particular.

摘要： A radio frequency (RF) multibit tag structure useful for identifying objects of interest is described. An array of thin cantilevers of slightly different lengths produced by differential etching are coated with a soft magnetic material which upon interrogation with an RF magnetic field vibrate at their resonant frequencies in the presence of an appropriate bias or direct current (DC) field. The oscillating magnetic fields generated by the vibrating bars and the stationary DC field can be readily detected by a receiver and processed to determine the code of the tag and thus provide information related to the object.

摘要： A programmable tag for being readable remotely and in a manner which does not require that the tag be held in a particular orientation, includes a first layer of material with electron spin resonance absorption, a second layer of hard magnetic material, and a third layer of soft permeable magnetic material. The second layer and third layer are in close proximity to the first layer. The second layer and the third layer impose a magnetic bias field on the first layer.

摘要： A string of bubble domains having a length equal to that of a column portion to be extracted from a bubble domain lattice array is laterally punched into the input side of the array at the height of the desired column portion. As it enters the array it displaces the adjacent and corresponding portion of the first column, which thus becomes a dislocation dipole. The latter is then propagated through the array by subsequent punching cycles until the corresponding portion of the last column is forced out of the array. At this point the dislocation dipole has passed completely through the array, and the corresponding portions of each column have been displaced one column to the right. The process is then repeated until the desired column portion has been displaced across the array into the last column, and then forced out of the array for reading. By punching the forced out column portions back into the array at the input side the original storage order of the array can be reestablished.
