摘要： Tamper-evident electric paper is made of two sheets of electric paper bonded together, the bottom sheet of which includes a pattern. Any attempt to erase a writing on the top sheet of electric paper results in the pattern on the bottom sheet of electric paper being erased. Therefore any tampering by erasure of a writing on the tamper-evident electric paper is revealed by the absence of a portion of the pattern on the bottom sheet of electric paper. Single sheet tamper-evident electric paper has a complex pattern, such as an encryption, printed on a single sheet of electric paper. Any attempt to erase a writing on the electric paper also erases a portion of the encryption, thereby providing evidence of tampering.

摘要： A method of making a substrate in which sets of optically anisotropic spheroidal balls are disposed, as for use in an electrical twisting ball display. First and second sets of spheroidal balls, are deposited on a receiving surface composed of an elastomer substrate material in an adhesive state, the spheroidal balls thus deposited adhering to the receiving surface. Balls of the first and second sets are physically distinguishable from one another. Balls of the first set can be deposited in a first arrangement, and balls of the second set, in a second arrangement. Each ball of each set has an optical anisotropy and an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the ball electrically responsive such that when the ball is rotatably disposed in an electric field while the electrical dipole moment of the ball is provided, the ball tends to rotate to an orientation in which the electrical dipole moment aligns with the field. With the balls thus deposited, additional, liquid elastomer material is poured over the balls adhering to the receiving surface, thereby covering the balls and forming an uncured substrate material in which the balls are disposed. This uncured substrate material is cured to form a substrate in which balls of the first and second sets are disposed. A plasticizer fluid can be applied to the substrate thus formed, thereby expanding the substrate so as to render the balls disposed in the substrate rotatable within the substrate.

摘要： There is described an optical-effect-producing medium comprising a carrier medium (1) containing or comprising pigment particles (10) having at least one optically responsive pigment or dye (100) that responds to incident electromagnetic radiation of at least a selected excitation wavelength or wavelength band (λEX) by producing an optical response in the visible or near-visible spectrum. A refractive index (n1) of the carrier medium (1) and a refractive index (n2; n3) of the pigment particles (10) are selected to maximise the amount of incident electromagnetic radiation reaching the said at least one optically responsive pigment or dye (100). Also described is the use of such optical-effect-producing medium to produce an optically responsive feature, especially for security, authentication and/or identification purposes, as well as objects comprising such an optically responsive feature.

摘要： A rotating element for use in an electric paper system in which the rotating element may be either substantially cylindrical or substantially spherical in shape and comprises at least three portions. Each portion has an associated optical modulation characteristic and the optical modulation characteristics of at least one portion are different from the optical modulation characteristics of at least one other portion. One of the portions is capable of being permanently magnetized. The rotating element also has an anisotropy for providing an electrical dipole moment. The electrical dipole moment renders the element electrically responsive such that when the rotating element is rotatably disposed in an electric field while the electrical dipole moment of the rotating element is provided, the rotating element tends to rotate to an orientation in which the electrical dipole moment aligns with the field.

摘要： A method of making rotating element sheet material utilizing magnetic latching is disclosed. First a plurality of rotating elements, each element having a magnetized segment, are mixed with an elastomer and a plurality of magnetic particles to attract the magnetic particles to the magnetized segments. Then a magnetic field is applied to orient the elements in a common direction. When the rotating elements have all been oriented in a common direction, they are held in that orientation for a long enough period of time to allow the magnetic particles to migrate in the elastomer to the regions of the elastomer in the vicinity of the magnetized segments of the elements. The elastomer is then cured to form an elastomer substrate with trapped rotating elements and magnetic particles. The elastomer substrate is then immersed into a bath of dielectric plasticizer which is absorbed more readily by elastomer than by the rotating elements. The elastomer substrate swells to create plasticizer-filled voids around the rotating elements. The magnetic particles remain incorporated within the elastomer to form magnetic material pads which are associated with an element.
摘要翻译：公开了一种利用磁性锁定来制造旋转元件片材的方法。首先，将具有磁化段的每个元件的多个旋转元件与弹性体和多个磁性颗粒混合以将磁性颗粒吸引到磁化段。然后施加磁场以使元件沿共同的方向定向。当旋转元件全部沿共同的方向定向时，它们被保持在该取向上足够长的时间段，以使磁性颗粒在弹性体中迁移到弹性体的磁化段附近的区域元素。然后将弹性体固化以形成具有捕获的旋转元件和磁性颗粒的弹性体基材。然后将弹性体基材浸入电介质增塑剂的浴中，其比由旋转元件更容易被弹性体吸收。弹性体基体膨胀以在旋转元件周围产生增塑剂填充的空隙。磁性颗粒保持结合在弹性体内以形成与元件相关联的磁性材料垫。
