Abstract: A single hand controller including a front surface and a back surface, with a first and second side surface there between and an upper surface and bottom surface. The upper surface includes a joystick, and the front surface has a proportional plunger and one or more switches. The controller is grasped by placing a user's finger tips on the front surface, with user's index finger operating the proportional plunger and remaining fingers operating the switches. The thenar eminence group of muscles of the user's hand rests against the back surface, whereby the user's thumb is disposed so as to operate the joystick.

Abstract: An intelligent data service unit (DSU) which terminates a digital subscriber loop is provided and includes a digital subscriber loop interface which receives incoming data from a DDS line of the service provider, a framing and signal converter for taking the incoming data and formatting the data for output, an output interface, a processor connected to the framing and signal converter and to each of the interfaces, and a data memory buffer coupled to the processor. All data provided to the DSU from the digital subscriber loop is reformatted by the framing and signal converter and propagated to the output interface as it is received. At the same time, a copy of the data is buffered into the memory, and the processor scans the memory to find and synchronize with an networking protocol frame (e.g., an IP frame) Once synchronized, the processor compares the destination address in the IP frame to the network address of the DSU. If the addresses match, the IP frame is stored for processing (e.g.
