Abstract: A device includes circuitry configured to determine characteristics of jammer signals associated with a first wireless protocol of another device. An amount of interference between the jammer signals and a first received signal at the device associated with a second wireless protocol is determined, and the jammer signals are filtered from the second received signal when the amount of interference between the jammer signals and the first received signal is greater than a first predetermined threshold.

Abstract: A digitally controlled circuit is arranged to provide the combined functions of level shifting, multiplexing, and delay control functions. The circuit is compact, and uses lower power and lower overall noise susceptibility over other solutions. A programmable bias current is arranged to adjust the delay through the circuit. The bias current can be provided by a digitally controlled current source, a binary weighted current DAC, or other digitally controlled means. The multiplexing functions are provided by an input stage circuit that is current limited by the programmable bias current. An output stage is arranged to convert signals from the input stage to a desired voltage level.

Abstract: A work machine system is provided. The system comprises an engine including an air intake system and an exhaust system. The engine is configured to operate efficiently at a defined intake manifold temperature. A cooling system includes a cooling unit mounted at the frontal area of the work machine. The cooling unit houses a cooling component for engine intake air that is undersized relative to a cooling component designed for engine intake air to be delivered to an intake manifold at the defined intake manifold temperature. A control system is configured to operate the engine and the cooling system so that intake air is delivered to the intake manifold at a temperature higher than the defined intake manifold temperature.

Abstract: A system is disclosed for optically coupling together first and second fiber optic cables, having different or similar core diameters, to enable light to be transmitted from the first fiber optic cable to the second fiber optic cable with a minimum of light loss. In a preferred embodiment of the invention, the system comprises a housing, first and second connectors, and first and second biconvex lenses. The first connector terminates the first fiber optic cable and also connects to a first housing portion of the housing to enable a first fiber end of the first fiber optic cable to protrude into the first housing portion. The second connector terminates the second fiber optic cable and also connects to a second housing portion of the housing to enable a second fiber end of the second fiber optic cable to protrude into the second housing portion.
