Most of web pages of the Web are inaccessible for the blind users. And the main reason is a lack of the semantics at the source code (technical) level of web pages and absence of the navigational components. In this work we propose a new web page representation---multiaxial navigation model---representing web documents in the form convinient for the blind users. Moreover, we present methodology for the navigation on the model proposed, that ensure an efficiency of user mobility. Automatic transformation of a web page into the multiaxial navigation model and navigation means are realized in the Blindzilla prototype. An efficiency of the proposed concepts is proven experimentally regarding contemporary screen readers, such as JAWS, Window-Eyes, and Fire Vox.

The article is devoted steps for the development technical support for crane operator training complex. An important component of technical support is a wireless terminals. Formulated a list of requirements for a wireless terminals: correct operation of the program crane simulator, reliability, compactness, wired and wireless communications to PC, flexible configuration, self-diagnostics, low price. Mobile Remote includes  terminals and host. The host is connected to PC via USB interface, as USB HID device. Terminals transmits the information to a host by Bluetooth. Selected hardware base for the terminals and host (microcontrollers, wireless modules, batteries) and designed printed circuit boards. Investigations of the different batteries and the battery life time of terminals. The description of the design decisions, especially this development.
