The first memory area is protected by hardware means against overwriting. The following method steps are performed. First, there is a system boot with the basic program from the first memory area. In such case, a system variable UPDATE is read. In case this has the value “perform update”, an invocation of a function “perform firmware update” occurs. Then this variable is set to the value “invalid firmware”. Next, a connection is established to a superordinated unit and the new software code is transferred into the device. Following storage of the new software code in the second memory area, a test of the new software code for bit error is performed. In case bit errors have occurred during the transfer, a new system boot is performed. If no bit errors have occurred, the new software code is executed from the second memory area and the system variable UPDATE is written with the value “valid firmware”. Through this method, a safe equipping of microprocessor-controlled devices with new software code via a communication network is possible. | 2009-08-27 |

| 20090217027 | Safe e-mail for everybody - Like wearing seatbelts. Like using condoms.

Furthermore, these applications change over time, rendering prior test scripts unworkable. The economic engine generates cost reports that reliably estimate the resources and time needed to produce new test scripts and test subsequent application versions, while greatly reducing the time, cost, and resource expenditures needed to arrive at subsequent application versions. | 2009-08-27 |
| 20090217101 | PROCESS AND DEVICE FOR MONITORING A MACHINE - A process for monitoring a machine, within the framework of a FMEA process for at least one component of the machine for at least one predetermined fault which can be diagnosed by means of a diagnosis diagram and a diagnosis system with sensors for detecting physical parameters of the machine, a diagnosis priority number being determined which is the product of the following index quantities: severity of the effect of occurrence of the fault with respect to the serviceability of the machine; expected machine-specific consequential costs when a fault occurs, and the possibility of correction of the fault. The diagnosis priority number is used in the evaluation of the diagnosis diagram, the diagnosis system, the current machine state, the necessary maintenance measures and/or the failure risk of the machine. | 2009-08-27 |
| 20090217102 | Fault Diagnosis of Serially-Addressed Memory Chips on a Test Adaptor Board To a Middle Memory-Module Slot on a PC Motherboard - A standard memory module socket is removed from a target DRAM module slot on the component side and the test adaptor board connects to the target DRAM module slot on the reverse (solder) side of a personal computer motherboard, or an extender card may be used. The target DRAM module slot is a middle slot, such as the second or third of four DRAM module slots. The first and fourth DRAM module slots are populated with known good memory modules storing the BIOS at a high address and an operating system image and a test program at a low address. The test program accesses a memory chip in a test socket on a test adaptor board that is connected to the target DRAM module slot to locate defects. The motherboard does not crash since the BIOS, OS image, and test program are not stored in the memory chip under test. | 2009-08-27 |
| 20090217103 | LOGICAL TO PHYSICAL CONNECTIVITY VERIFICATION IN A PREDEFINED NETWORKING ENVIRONMENT - A method, information system, and computer readable storage medium verify predefined connectivity for I/O devices. Current predefined logical connection data and actual physical connection data is gathered. The predefined logical connection data and the actual physical connection data are formatted into a plurality of sortable tables. At least a portion of the predefined logical connection data is formatted into a predefined channels table and at least a portion of the actual physical connection data is formatted into a node information table. The portion of the predefined logical connection data is compared with the portion of the actual physical connection data. The portion of the predefined logical connection data is determined to substantially match/not match the portion of the actual physical connection data. At least one predefined logical connection associated with the predefined logical connection data that fails to substantially match the actual physical connection data is displayed to a user. | 2009-08-27 |
