20120227404 | Thermodynamic Machine and Method for the Operation Thereof - The invention relates to a thermodynamic machine having a circulation system in which a working fluid, in particular a low-boiling working fluid, circulates alternately in a gaseous and a liquid phase, a heat exchanger, an expansion machine, a condenser, and a fluid pump. The invention also relates to a method for operating the thermodynamic machine. According to certain embodiments of the invention, in the flow line of the fluid pump, a partial pressure increasing the system pressure is applied to the liquid working fluid by adding a non-condensing auxiliary gas. Compact ORC machines can be implemented, preventing cavitation in the liquid working fluid. | 09-13-2012 |

20120206957 | Identifying and Correcting a Bit Error in a FRAM Storage Unit of a Semiconductor Device - An embodiment of semiconductor device including a control unit and an FRAM storage unit is disclosed. The FRAM storage unit contains FRAM cells. The control unit includes a predetermined test data pattern. The control unit is configured to read the FRAM cells that contain a test data pattern in a margin-mode, compare the read out bit information with the test data pattern to determine whether a bit error is present in the dedicated FRAM cells. When a bit error is present, the control unit is configured to read-out the complete FRAM storage unit in a recovery-mode and refresh all FRAM cells of the FRAM storage unit by writing back the read out bit information to the respective FRAM cells. In the margin-mode, the read operation is performed using a lower read-sensitivity compared to the read operation reading out the complete FRAM storage unit that is performed in the recovery-mode. | 08-16-2012 |
20140050008 | Electronic Device and Method for FRAM Power Supply Management - The invention is an electronic device including a ferroelectric random access memory (FRAM), a first supply voltage domain, a second supply voltage domain and a low drop output voltage regulator (LDO) receive a first supply voltage of the first supply voltage domain and providing a second supply voltage of the second supply voltage domain. The second supply voltage domain supplies the FRAM. The LDO switches between a first state providing and maintaining the second supply voltage of the second supply voltage domain and a second state providing a high impedance output to the second supply voltage domain. The electronic device switches the LDO from the first state to the second state in response to a failure of the first supply voltage domain. | 02-20-2014 |

20130006466 | METHOD FOR EXAMINING A STATE OF AN ELECTRIC CIRCUIT OF A MOTOR VEHICLE - A method for examining a state of an electric circuit of a motor vehicle, in particular a motor vehicle with an electric engine, is described. First, a state for the circuit is requested. Then, it is checked whether the requested state is actually set, by measuring with a measuring device of the motor vehicle a current value for a variable related to the circuit and comparing with a control unit of the motor vehicle the current value with values for the variable specified for the requested state of the circuit. If the control unit determines that the requested state for the circuit is set, this information is displayed. A motor vehicle for carrying out the method is also described. | 01-03-2013 |
