摘要： Multi-state switchability is highly desirable in optoelectronic devices. For liquid crystal (LC) based devices, the stability of any configuration is achieved through a balance between imposed interactions and the LC's orientational elasticity. In most cases, the latter acts to resist deformation. By combining surface topography and chemical patterning, provided here are the effects of saddle-splay orientational elasticity, a property that, despite being intrinsic to all LCs, is routinely suppressed. Utilizing theory and continuum elastic calculations, provided here are example conditions for which, even using generic, achiral LC materials, spontaneously broken surface symmetries develop. Also provided are multi-stable devices in which a weak, but directional, applied field switches between spontaneously-polar surface state domains. The disclosed approach is useful in low-field and fast-switching optoelectronic devices, beyond those attainable by current technologies.

摘要： Disclosed is a brassiere having breast cups configured with inflatable bladders specifically positioned and configured to manipulate the breast tissue of a target breast into a lifted position whilst simultaneously displacing laterally sideways/outward and downward a contra-lateral breast. The brassiere is configured to lift the target breast away from the chest wall and to stabilise the breast so as to increase treatment accuracy and reduce radiation dosage to high risk organs such as the heart and lung. The brassiere according to the subject invention is advantageous to be worn by women for the treatment of either the left or right breast whilst providing modesty during treatment delivery.
