Abstract: A primary game controller for use by a mobility impaired person by interfacing with a peripheral controller that allows the user to input precise movements needed for certain game functions. The peripheral controller may be operated by a part of a user's body in which the user has sufficient motor control, while the primary game controller may provide control inputs that require lesser motor control to operate. A control unit on the game controller may transmit control signals from the game controller and the peripheral controller, or may exclusively use the peripheral controller as the input for certain game functions. The game controller may be sized to be able to rest on a user's lap and to provide bigger control inputs.

Abstract: A receiver is provided with a digital signal processing circuit to process a receive signal. In addition, the receiver includes an interference detector to detect an interference scenario affecting reception of the signal by the receiver. Depending on the interference scenario detected by the interference detector, the digital signal processing circuit is adapted.

Abstract: A filter arrangement comprises a switching element coupled to a filter input, wherein the switching element is controllable by a reference clock signal. The filter arrangement further comprises an input storage element, an output storage element, and a first and a second auxiliary storage element. The first and the second auxiliary storage element can each be connected in parallel to the input storage element or to the output storage element depending on a switching signal. The output storage element is coupled to a filter output. The filter arrangement can be used as a loop filter in an analog-to-digital converter, wherein the output signal of the filter arrangement is quantized to provide an output word. Respective feedback signals can be generated from the output word and be provided to the storage elements.

Abstract: A shaped zeolite-containing body, e.g., zeolite-containing monoliths, having high compressive strength is prepared from a particular class of siloxane-based binders in combination with zeolite, plasticizing agent, and methylcellulose. It has been discovered that when using the particular class of siloxane binder with the aforementioned components, the body formed therefrom can be processed and calcined at temperatures below 300° C., thereby reducing costs typically seen with other processes for preparing shaped materials containing zeolite. The shaped bodies of this invention have been shown to have compressive strengths of at least 20 N/mm2 or more.

Abstract: The disclosure is directed to a large composting system as well as to a new composting method for the automatic production of compost. A mobile layer rearranging unit includes a conveyor system which is changeable with respect to length can be remote-controlled so that the influx of rotting matter is optimized according to throughput and rotting time and the rot loss is compensated for by repeatedly restoring the complete rot height. The required space requirement is less than before. Any mechanical intervention has a loosening effect, particularly in that the working device comprises upwardly working digging and conveyor wheels. All important parameters for the compost ripening can be monitored via free programming as well as by control by the system maintenance personnel.
