Abstract: A hybrid vehicle having a hydrogen powered internal combustion engine employing a cylinder deactivation strategy during idle or light load conditions. A continuous stream of air is supplied to the hydrogen internal combustion engine. A control system responsive to engine speed and accelerator pedal position calculates a specific amount of hydrogen to inject into the continuous air stream. The resulting stream is combusted in the engine to provide power to the vehicle. During idling or light load conditions, the hydrogen supply to one or more cylinders may cease while maintaining the flow of air to the cylinders. A rechargeable battery and an electric motor receiving power from the battery are used to supplement the hydrogen powered internal combustion engine.

Abstract: A system for analyzing the behavior of electronic devices includes a first database for storing simulation values and a second database for storing actual waveform values. The system further includes software for aligning the values stored in the first and second databases, so that simulated and actual values can be readily compared. Analysis tools are included for examining similarities and differences between simulated and actual behavior.

Abstract: A system for analyzing the behavior of electronic devices includes a first database for storing simulation values and a second database for storing actual waveform values. The simulation values include test patterns representing inputs to a device model, response data representing outputs from the device model, and expect data representing expected values of the response data in response to the test patterns. The actual waveform values include sampled inputs and outputs of an actual device under test (DUT), of the type presented by the model, and acquired using an electronic test system. When the DUT is exercised with test patterns that correspond to the test patterns stored in the first database, the DUT generates output that can be compared directly with the response data and/or expect data stored in the first database. The system according to the invention further includes software for aligning the data stored in the first and second databases, so that simulated and actual values can be readily compared.
