Abstract: The invention concerns a pluggable data transfer module and a method that can be used to transfer data from an analytical system to a data processing unit in a galvanically decoupled manner. This invention is particularly suitable for medical fields of application in which recently it has become more and more desirable to process analytical data of a patient.

Abstract: The invention relates to a brake system for a vehicle having at least one brake circuit which includes at least one wheel brake, one inlet valve, one outlet valve, and one return device. The return device has at least one first pump device and one second pump device, having respective inlet valves and outlet valves. The pump devices have a delivery cycle offset from each other. An additional valve is located in every supply line of every pump device for preventing negative pressure produced in an intake phase of one of the pump devices from being applied to an inlet valve of another pump device.

Abstract: A piston pump for brake systems employs a pulsation-smoothing device that functions especially well in the region of the outlet valve. As a result, substantially less noise occurs, and the durability of the piston pump is substantially better. The piston pump is used essentially in traction-controlled motor vehicle brake systems.

Abstract: Computer programs and computer-implemented methods implement techniques for evaluating experimental data from a library of materials. The techniques receive a plurality of images of a library of materials that includes an array of members associated with locations in the library. User input identifying a plurality of regions of interest is received. A series of reduced data values is determined for one or more of the regions of interest as a statistical function of a plurality of pixel values for pixels in the corresponding regions. A figure of merit is calculated from one or more of the series of reduced data values for a library member at the corresponding library location. The regions of interest include a plurality of pixels in the images and correspond to locations in the library.

Abstract: A pressure accumulator has a housing having at least one pressure medium opening, a diaphragm chamber arranged inside the housing and having a side wall which is at least partially deformable, and a pressure medium chamber arranged outside of the diaphragm chamber, the pressure medium chamber at least partially being limited by a partially permeable material which allows an exit of gas from the pressure medium chamber but prevents an exit of a pressure medium from the pressure medium chamber.

Abstract: Computer programs and computer-implemented methods are disclosed for extracting and analyzing combinatorial chemical data from images. The invention receives a stream of data, identifies a plurality of regions of interest and determines a series of values for one or more regions of interest. The library includes a plurality of members. The data stream includes a series of images of the library. Each region of interest corresponds to a location in each of the images and to a location in the library. The series of values for each region includes a value for each of the images. Particular embodiments have the following features. The invention calculates a figure of merit for a library member from each series of values. The stream of data comprises a series of images generated at a frequency of greater than about 1, 6, 12 or 30 frames per second. The series of images is captured from a beginning of a combinatorial experiment to an end of a commercial experiment.

Abstract: The invention relates to a roller bearing, in particular a needle bearing (38). The invention proposes embodying a bearing ring (42) of the needle bearing (38) with a lateral extension (46) with which the needle bearing (38) can be pressed into a bearing seat (48). This has the advantage that a compression of the bearing ring (42) by the bearing seat (48) takes place outside the region of the needles (40) of the needle bearing (38) and consequently, the compression of the bearing seat (48) does not influence a bearing play of the needle bearing (38). The needle bearing (38) is particularly provided for supporting a shaft (24) of a piston pump (16) of a pump unit (10), which shaft supports a cam (26).

Abstract: The invention relates to a piston pump (10) for a hydraulic vehicle brake system that has traction control. The invention proposes embodying the piston pump (10) with a piston ring (24), for instance a PTFE, which ring serves as both a sealing and a guide ring. The invention lessens the effort and expense of assembly as well as the production costs for the piston pump (10). To achieve reliable sealing, the invention proposes embodying the piston ring (24) with an internal cone on its side toward a pump chamber (18), so that during a pumping stroke, the piston ring (24) is subjected to pressure from the pump chamber (18) and is pressed into sealing contact against a pump bore (12).

Abstract: A method of employing a hydraulic unit of a brake system containing brake lines extending between a master cylinder and wheel brakes and valves which are actuatable by exertion of magnetic force and which have removable electrical coils and when unactuated assume their blocking position, including the steps of removing coils from the valves; connecting the hydraulic unit, toward the master cylinder or the wheel brakes, to an air source of adequately high pressure; switching the valves to their open position by the exertion of magnetic force of a permanent magnet; positively displacing the pressure medium contained in the hydraulic unit from the air source by air and caught.

Abstract: A pump assembly having a piston pump, which is driven by an eccentric element. To prevent leakage brake fluid from reaching an eccentric element chamber, a groove surrounds the pump piston in the pump housing and a seal and a porous metal sintered ring is inserted into the groove. A drain which extends obliquely downwardly from the groove drains leakage fluid from the sintered ring.

Abstract: A motor-and-pump unit having an electric motor in combination with a housing of the pump. The pump has at least one displaceable pump piston. To that end, on the side toward the pump housing and originating at one end wall, the electric motor has a bearing neck, which is tubular and into which the pump housing protrudes. This bearing neck fixes an outer ball bearing race of a ball bearing for a shaft of the electric motor. Protruding from the ball bearing is a shaft end that carries an eccentric element for moving the at least one pump piston. The eccentric element is disposed at an axial spacing from an inner ball bearing race that surrounds the shaft in stationary fashion. The eccentric element is brought directly up to the inner ball bearing race, and the inner ball bearing race and the eccentric element are embodied as a one-piece, multifunctional component.

Abstract: A piston pump, which is provided as a return feed pump for a slip-regulated motor vehicle brake system. In order to simplify the manufacture, a sleeve in the form of a tubular piece is clamped between a fastening element which is inserted into the cylinder bore using a self-clinching technique, and the cylinder bore, and is thus sealed and fixed in place. In addition to the simple manufacture of the sleeve out of reasonably priced tubular material, the piston pump has the advantage of a sealing of the sleeve in the cylinder bore without a separate sealing element such as a sealing ring.
