| 20080201049 | Vehicle Brake System Having A Pump - Disclosed is a vehicle brake system having a pump and a prechamber, from which the pump can extract a fluid by suction, and having a switching valve, by means of which fluid can optionally be fed to the prechamber. A bypass valve connected in parallel with the switching valve is switched as a function of the pressure difference between the ambient pressure and the prechamber pressure. | 08-21-2008 |
| 20090055067 | METHOD AND DEVICE FOR CARRYING OUT A STATIONARY HOLDING FUNCTION ON A MOTOR VEHICLE - A method for controlling a valve for maintaining brake pressure in a specified region of a brake circuit in a motor vehicle, in which the valve is controlled using a first control method, the specified region of the brake circuit is monitored with respect to the occurrence of a loss of brake pressure, and in response to a detected loss of brake pressure, the valve is controlled using a second control method. | 02-26-2009 |
| 20090289494 | METHOD FOR RELIABLY CLOSING A SOLENOID VALVE - A method is for closing a solenoid valve in which the solenoid valve is charged with a first current value that results in a first closing of the solenoid valve, and the solenoid valve is subsequently charged with a second current value that results in a renewed partial opening of the solenoid valve, and the solenoid valve is subsequently charged with a third current value that results in a second closing of the solenoid valve, the third current value being selected such that the second closing takes place with a higher closing speed of the solenoid valve than does the first closing. | 11-26-2009 |
| 20110001351 | Method and Device for the Reproducible Generation of a Specifiable Final Pressure in a Braking System - To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve. | 01-06-2011 |

| 20080253086 | Thermal cooling of industrial electronic module by conductive structure - An electronic module and chassis/module installation and cooling method are disclosed. The installation comprises a chassis including a metallic heat input region. An electronic module including an electronic component is adapted to be connected to the chassis. An uninterrupted thermal pathway thermally connects the electronic component of the module to the heat input region of the chassis. The thermal pathway comprises a chimney, a heat channel thermally connected to the chimney, and a heat output block thermally connected to the heat channel. A first electrically insulative non-metallic layer thermally couples the chimney to the electronic component. A second electrically insulative non-metallic layer thermally couples the heat output block to the chassis heat input region. | 10-16-2008 |
| 20090008880 | INDUSTRIAL AUTOMATION INPUT OUTPUT MODULE WITH ELASTOMERIC SEALING - An industrial automation input output module is protected against ingress of water, oil, debris, dirt and other contaminants without use of a potting compound. An elastomeric main seal provides a fluid-tight connection between inter-fitted inner and outer housing members that define a housing of the module. The one-piece main seal includes an integral light pipe portion with at least one light pipe that communicates light from an LED or other light source to a visual indicator opening in the housing, and the light pipe portion is also sealed to the housing to prevent ingress of contaminants through the visual indicator opening. Connectors pass through a wall of the housing and connector seals are used to prevent ingress of contaminants between the connectors and the housing. The connectors are also secured against rotation relative to the housing. | 01-08-2009 |
| 20090125156 | ENERGY STORAGE MODULE - An industrial automation controller module includes a main module and an energy storage module (ESM) releasably connected to the main module. The ESM includes a back-up electrical power source such as a battery or a capacitor that is electrically connected to processor circuitry of the main module when the ESM is physically connected to the main module. In case of interruption of operating power to the processor circuitry of the main module, the back-up power source of the ESM supplies back-up power to the main module to allow for completion of an emergency save operation to save data to non-volatile memory in the main module. If the ESM includes a capacitor back-up power source, it is charged by the main module and the capacitor charge is dissipated if the ESM is separated from the main module. In all cases, the ESM can include one or more configuration parameters stored therein that allow the main module to validate (or not) the ESM for the requirements of the main module, with respect to type of back-up power source, product code or model, capacity of back-up power source, and the like. The main module can also initiate periodic testing of the back-up power source of the ESM. | 05-14-2009 |

| 20100314522 | INTEGRATED DIN RAIL ATTACHMENT FEATURE FOR SUPERIOR ATTACHMENT - An electronics module includes a base and a cover connected to the base. The base includes a recess adapted to receive an associated mounting rail. At least one fixed rail constraining tab is located adjacent a first edge of the recess and is adapted to engage a first flange of the associated mounting rail. First and/or second latch arms are located adjacent a second edge of the recess that is opposite the first edge of the recess. The first and second latch arms are connected to a fixed portion of the second edge and project outwardly relative to opposite lateral sides of the fixed portion. Each of the first and second latch arms includes a rail capture tab. The first and second latch arms are selectively movable resiliently to and from latched and unlatched positions, wherein the rail capture tabs of the first and second latch arms project beyond the fixed portion of the second edge and into the recess when the first and second latch arms are located in their respective latched positions, and wherein the rail capture tabs of the first and second latch arms are withdrawn relative to the fixed portion of the second edge when the first and second latch arms are located in their respective unlatched positions. The cover or other portion of the module defines first and second receiving locations that receive and retain portions of the first and second latch arms when the first and second latch arms are located in their respective latched positions. | 12-16-2010 |
| 20110002100 | OVERMOLDED ELECTRONICS ENCLOSURE - An enclosure for electronics includes a body with a metal component and a polymeric component overmolded onto the metal component so as to be connected to the metal component without fasteners.
