Abstract: A method for preventing hijacking of a web page is provided. A HyperText Markup Language (HTML) source file is received from a web server in response to a HyperText Transfer Protocol (HTTP) access request, the HTML source file being embedded with a script tag corresponding to script code for preventing HTTP hijacking. The script code for preventing HTTP hijacking is pulled from an antihijacking server according to the script tag. It is detected, based on the script code for preventing HTTP hijacking, whether a document object model (DOM) node used for HTTP hijacking exists in a DOM tree. The DOM node used for HTTP hijacking is hidden from a web page of a browser in response to detecting that the DOM node used for HTTP hijacking.

Abstract: A multi-layer piezoelectric microactuator assembly has at least one poled and active piezoelectric layer and one poled but inactive piezoelectric layer. The poled but inactive layer acts as a constraining layer in resisting expansion or contract of the first piezoelectric layer thereby reducing or eliminating bending of the assembly as installed in an environment, thereby increasing the effective stroke length of the assembly. Poling only a single layer would induce stresses into the device; hence, polling both piezoelectric layers even though only one layer will be active in use reduces stresses in the device and therefore increases reliability.
