Abstract
A new class of thin client called a trans client for operation with a smart cellular telephone as its server does not contain its own user interface (UI) and operating system (OS) and has no capability to run user programs as a standalone apparatus. Its purpose and capability is to display remote content and to provide user input interface. It is built with the slowest processing and lowest power consumption possible with the lowest cost and has security features to assure integrity of operations.
Claims12
A client apparatus for providing an enhanced user interface for a cellular telephone operative as a server comprising:
- a low-power embedded microprocessor operative under control of a relatively slow system clock;
- USB Host-type ports;
- embedded operating system as a single nonextendable image;
- nonexpandible random access memory;
- nonexpandible persistent memory;
- an internal hardware-based video display engine;
- and
- firmware incorporating data processing protocols to limit usage of said CPU, such that said apparatus is dependent upon the cellular telephone for functionality.
A client apparatus for providing an enhanced user interface for a portable normally client device operative as a server, the client apparatus comprising:
- a video interface element operative to receive video commands from the normally client device and displaying a corresponding output;
- a user interface input operative to receive interrupt events, including keyboard and mouse commands and an output for conveying the interrupt events to the normally client device;
- and
- an output interface for supplying displays to a display element.
