| 20100119387 | DEVICE FOR SUPPLYING FUEL - Devices for supplying fuel are already known, having a supply unit which has a pump housing connected to an electrical ground and is supported on a pump mount.

| 20100186194 | HOLDING ELEMENT FOR HOLDING AN ASSEMBLY IN A HOLDER, AND FASTENING ARRANGEMENT - Holding elements are known for holding an assembly in a holder, comprising a holding section for engaging behind the assembly and holding members that are provided on the holding section for holding the assembly in the holder. It is disadvantageous that the holding element is comparatively expensive to produce. For example, it is configured very rigidly in the holding direction, which is achieved with a comparatively high amount of material. This results in high production costs. In addition, in the case of very high mechanical loads the detent connection can detach due to torque acting on the detent hooks. The holding element according to the invention is simplified, thereby lowering the production costs. According to the invention, the holding section has a flat configuration viewed in the holding direction, and the holding members are angled in relation to the holding section and configured as elastically resilient holding arms. | 07-29-2010 |
| 20100200595 | FUEL DELIVERY MODULE - Fuel delivery modules are already known having a tank flange and having an accumulator pot which is connected to the tank flange by means of at least one guide rod and which is mounted so as to be axially movable along the guide rod, where the guide rod is pressed with one end into a receptacle of the tank flange. It is disadvantageous that the receptacle is expanded over the entire longitudinal extent as the guide rod is pressed in. As a result of tolerance fluctuations in production, excessively high pressures can occur in the receptacle here, which pressures can cause cracks in the receptacle. This leads to rejects and therefore to high production costs. In the fuel delivery module according to the invention, damage to the receptacle during assembly is prevented. According to the invention, it is provided that that end of the guide rod which faces toward the tank flange has a bead, which interacts in a retentive manner with the receptacle, and a constriction situated behind the bead in a direction facing away from the tank flange. | 08-12-2010 |
| 20100319793 | SUCTION JET PUMP - Suction jet pumps are already known with a driving line which leads via a jet outlet into a suction chamber, where the suction chamber has a suction opening which interacts with a valve element and through which fluid can be sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank and sucks fuel out of a fuel tank into the storage tank. At low levels in the fuel tank, air may sometimes be sucked up and conducted into the storage tank, as a result of which foaming occurs in the storage tank. However, the large volume of the foam causes fuel to be displaced, which may result in partial emptying of the storage tank. This effect is also referred to as dynamic leakage. A characteristic curve of the suction jet pump that represents the suction power as a function of the driving stream has a comparatively steep gradient. Severe foaming occurs only above a critical suction power of the suction jet pump, referred to below as the foam limit. In the case of the suction jet pump according to the invention, foaming is avoided or at least reduced. According to the invention, it is provided that the driving line has a bypass opening which leads into the suction chamber and is arranged in such a manner that the bypass stream thereof acts on the valve element. | 12-23-2010 |
| 20110000468 | DEVICE FOR FEEDING FUEL - Devices for feeding fuel are already known which have a storage pot which can be filled by a suction jet pump. The storage pot has a pot base with an intake opening which opens into an intake chamber of the suction jet pump and through which the suction jet pump sucks in fuel. The intake chamber is fluidically connected to the storage pot via a mixer duct. A non-return valve is provided in the intake opening in order to prevent fuel from back-flowing. Considerable flow turbulence occurs within the suction jet pump, which flow turbulence can lead, in particular in the case of heated fuel, referred to as hot petrol, to the formation of gas bubbles. The delivery capacity of the suction jet pump is considerably reduced by the gas bubbles, with the result that under certain operating conditions the storage pot is not sufficiently filled and can run empty. In the device according to the invention, the flow turbulence is reduced. The invention provides that an oblique ramp for guiding the flow with little turbulence is provided at the junction with the mixer duct on the pot base of the storage pot inside the intake chamber. | 01-06-2011 |

For example, a system can be used to evaluate a plurality of configurations, and/or to select (and/or allow a user to select) an optimal configuration of the disk group, based, in some cases, on the relative estimated mean times to data loss of the various configurations. This can allow, if desired, the configuration of the disk group to minimize the likelihood of data loss in the disk group. | 04-22-2010 |
| 20100228999 | Trusted Storage Systems and Methods - Systems and methods are disclosed for providing a trusted database system that leverages a small amount of trusted storage to secure a larger amount of untrusted storage. Data are encrypted and validated to prevent unauthorized modification or access. Encryption and hashing are integrated with a low-level data model in which data and meta-data are secured uniformly. Synergies between data validation and log-structured storage are exploited. | 09-09-2010 |

| 20130318129 | SYSTEMS AND METHODS FOR ASYNCHRONOUS SCHEMA CHANGES - This disclosure provides systems and methods for updating database servers with schema changes to avoid concurrency anomalies. The system may receive a snapshot of a table to be updated with a new schema, wherein the snapshot is taken at a given time, and wherein the table includes a number of rows. The system may then read each row from the snapshot and read each row from the table to be updated at a second time. The system may then compare the rows read from the snapshot to the rows read from the table at the second time. Furthermore, the system may determine, based on the comparison, the rows from the snapshot that have not changed between the given time and the second time. The system may then write the rows that have not changed to the table to be updated. | 11-28-2013 |
