A flame retarding polymer electrolyte composition containing maleimides includes a modified maleimide; a lithium salt; and at least one ionic solution in a ratio of at least 2 wt % relative to the total weight of the composition. An optical system is arranged between the optical modulation element and an predetermined plane. An optional second display is a transparent imaging panel that acts selectively as a light valve, as a display platform for special effects or for providing the appearance of linear motion towards or away from the observer. In another embodiment, the enhanced immune response is a protective immune response. When a third client issues a log request with a specific search keyword, a log searcher retrieves relevant policy log records and access log records that match with the specified search keyword. The sensor have a pair of sensor contact pads that are positioned on the shaft for contact with the pair of sensors such that during transmission of microwave from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.
