Abstract: Machine learning image analysis for quantitative and qualitative analysis of agglutination samples. A method includes receiving an image of an agglutination assay comprising a negative control sample, a positive control sample, and a test sample. The method includes providing the image to a machine learning algorithm trained to classify agglutination of the test sample on a quantitative scale. The machine learning algorithm calibrates the quantitative scale based at least in part on the negative control sample and the positive control sample.

Abstract: Protecting information by partitioning data across multiple storage resources. A method includes receiving an image of a test card and an identity of a patient associated with the test card. The method includes associating the image of the test card with the identity of the patient as a data pair on a first storage resource. The method includes providing the image of the test card to a second storage resource by way of a network, wherein the first storage resource is independent of the second storage resource. The method includes receiving a result for the test card and associating the result for the test card with the identity of the patient based on the data pair stored on the first storage resource.

Abstract: Machine learning analysis for classifying agglutination of fluid samples. A method includes scanning a unique scannable code printed on a test card, wherein the test card comprises a negative control fluid sample, a positive control fluid sample, and a test fluid sample. The method includes capturing an image of the test card and providing the image of the test card to a machine learning algorithm configured to assess agglutination of the test fluid sample based on the image. The method includes receiving from the machine learning algorithm one or more of a qualitative analysis or a quantitative analysis of the agglutination of the test fluid sample.

Abstract: Test cards for agglutination assays, wherein the test cards are configured for computer-implemented image analysis. A test card includes a negative control test region for receiving a negative control fluid sample, a positive control test region for receiving a positive control fluid sample, and a test sample region for receiving a test fluid sample. The test card includes one or more unique scannable codes comprising data for instructing a processor to capture an image of the test card that is suitable for computer-implemented image analysis.

Abstract: The present invention is a method and kits for generating a homogenous population of hematopoietic progenitor cells capable of differentiating into a hematopoietic cell lineage. Whereas the combination of Homeobox-B8 protein and FMS-like tyrosine kinase 3 ligand generate cells with the potential to differentiate into different myeloid and lymphoid cell types, Homeobox-A7 protein and erythropoietin generate cells with the potential to differentiate into erythropoietic or thrombopoietic cell types.

Abstract: A silencer is described for damping the outflow noise of compressed air from compressed air appliances, in particular compressed air appliances of vehicles, with an inlet port, with at least one outlet port and with a pot-like housing which is arranged between these ports and which has a pot casing and a pot bottom, a sound-absorbing material in the form of a cartridge of a filter knit, serving for noise damping, being arranged in the inner space of the pot-like housing, characterized in that a layer of fibrous material is arranged between the cartridge and the pot casing.

Abstract: Electropneumatic control valve for a pneumatic brake system of a vehicle having a relay valve housing in which an axially adjustable control piston is arranged for actuating a valve seat arrangement which switches the compressed-air flow between at least one exterior brake line connection, a supply pressure connection and a bleeder connection. The control piston is axially guided by means of a coaxial guiding arrangement. The guiding arrangement comprises a separate guiding sleeve which is stationarily fastened to the pilot valve housing and which is provided with an upper guiding section which, for the axial guidance, corresponds with a passage bore in the control piston, and which, in addition, has a lower tube section of a smaller outside diameter adjoining the upper guiding section in order to guide the outgoing air flowing through an integrated axial bleeder duct directly to the bleeder connection.

Abstract: Electropneumatic control valve for a pneumatic brake system of a vehicle having a relay valve housing (1) in which an axially adjustable control piston (5) is arranged for actuating a valve seat arrangement (8) which switches the compressed-air flow between at least one exterior brake line connection (11), a supply pressure connection as well as a bleeder connection (13), the control piston (5) being axially guided by means of a coaxial guiding arrangement and being capable of being acted upon by way of at least one electromagnetic pilot valve (6) for the axial adjustment, which pilot valve (6) is accommodated in a pilot valve housing (2) connected with the relay valve housing (1), in which case the guiding arrangement of the control piston (5) according to the invention comprises a separate guiding sleeve (17) which is stationarily fastened to the pilot valve housing (2) and which is provided with an upper guiding section (19) which, for the axial guidance, corresponds with a passage bore (18) in the control

Abstract: A hydraulic emergency control for changing the hydraulic oil pressure in the hydraulic conical pulley axial adjustment mechanism of a continuously variable transmission (10) for varying the clamping force ratio has a pump (20) in an open hydraulic circuit that supplies the respective piston chambers (17, 13) of the secondary and primary axial adjustment mechanisms with hydraulic oil. The primary and secondary oil pressures are regulated by separate oil pressure limiting valves (30, 40). At least one throttle valve (51) is arranged between the pump (20) and the output pipe (92) of the open hydraulic circuit, at a point where the pump volumetric flow can be influenced. The hydraulic emergency control allows a starting transmission ratio to be set in a low range when starting the vehicle, whereas a very small reduction ratio is selected at a high driving speed and at light throttle.

Abstract: A hydraulic emergency control system for a continuous looped gear type continuously variable transmission (10) includes first and second hydraulic beveled conical pulley axial actuators controlling a gear ratio. A pump supplies a first piston chamber (13) of said first axial actuator via a sensor valve (20), wherein the sensor valve (20) is controlled by a flow control valve (73) connected downstream of the pump (80). The pump (80) supplies a second piston chamber (17) of the second axial actuator, with a pressure relief valve (40) limiting fluid pressure in said second piston chamber. Fluid in the second piston chamber (17) is controlled as a function of the fluid pressure in the first piston chamber (13) via a control line (52, 113).
