Abstract: An electronic unit comprises a microcontroller with a control input, a control output, and a signal input; and an interface circuit with a connection terminal, a control output, a control input, and a signal output. Both the microcontroller and the interface circuit each have a first operating mode and a second operating mode. The microcontroller is designed to cause the interface circuit to operate in its first operating mode. The interface circuit is designed to convert an input signal into a derivation signal representing a derivation of the input signal over time and to generate a control signal from the derivation signal. The microcontroller is designed to cause the interface circuit to operate in its second operating mode and to receive and convert a digital input signal and to output an output signal to the microcontroller.

Abstract: Systems and methods are provided which includes a client receiving a global positioning system (GPS) signal, communicating the GPS signal to a universal client program, encoding the GPS signal by the universal client program, transmitting the encoded data to a server, receiving value added data an application program that has a synchronized state with the universal client program from server computer, and enabling viewing of the value added data on the client.

Abstract: Systems and methods are provided through which an application is executed on a server, and operated from a client operably coupled to the server. State information of the application is maintained through parallel objects on both the client and the server, thereby minimizing the communications requirements between the client and the server in the operation of the application. More specifically, the communications requirements and updates of attributes of the application is minimized.
