Abstract: A fuel system for an engine of a vehicle and a method of operating the fuel system are described. As a non-limiting example, the fuel system is controlled in response to engine operating conditions.
Abstract: A method of tracking a target includes receiving an observed depth image of the target from a source and obtaining a posed model of the target. The model is rasterized into a synthesized depth image, and the pose of the model is adjusted based, at least in part, on differences between the observed depth image and the synthesized depth image.
Abstract: An electrochemical sensor is provided especially for gases. The electrochemical sensor has a mediator compound, which is both dissolved in an electrolyte (9) in a saturated form and is present as an excess solid (10) in the electrolyte (9).

Abstract: A method for manufacturing bone milling cutters, wherein a milling cutter toothing (12) is created at a distal face of a tubular milling cutter shaft (10) of a bone milling cutter at a given outer diameter (D) of the milling cutter shaft (10). The following steps are carried out: determining the tube circumference (U) of the milling cutter shaft (10); ascertaining an average desired tooth height (Hgew) of the milling cutter toothing (12); ascertaining the desired tooth period length (LZ?) of the milling cutter toothing from the desired tooth height (Hgew) at given parameters of a tooth period pattern; dividing the tube circumference (U) by the desired tooth period length (LZ); rounding the results to an even number value (Qz); and dividing the tube circumference (U) by the value (Qz) in order to obtain the tooth period length (LZ).
Abstract: A support device for pneumatic prehensile members, in particular suction cups, for picking up and moving the parts, items and the like. It includes a fixed support body (support body) a tubular rod (12) moving axially in the body, and a return spring (13) between the body and rod. Between the tubular rod (12) and a distal end of the fixed support body (support body) are interposed some guide elements (14) provided to prevent torsion/rotation of the rod during its longitudinal movements in and with respect to the fixed body.
Abstract: A device is provided for adsorbing and desorbing anesthetic has good control of anesthetic dispensing such as in an anesthetic system. An adsorption filter is provided with adsorption beds (13, 14), which can be pivoted between an inspiration line (4) and an expiration line (6). The anesthetic is dispensed in the expiration line (6) on the incoming flow side of the adsorption bed (14) arranged there.

Abstract: A method of operating a vehicle including an engine is provided The engine may include at least one cylinder, a boosting device to boost intake air to the at least one cylinder, a fuel tank, a fuel vapor canister to store fuel vapors vented from the fuel tank, and an emission control device to treat exhaust gas from the engine. The boosting device includes a compressor at least partially driven by an electric motor. The method includes during an engine cold start condition, operating the electric motor of the boost device to boost intake air, directing the boosted intake air through the fuel vapor canister to release a fuel vapor stored in the fuel vapor canister, directing the fuel vapor from the fuel vapor canister to the engine, and performing combustion in the at least one cylinder using the fuel vapor during the engine starting.

Abstract: A process for operating a fuel cell system (2) arranged in a vehicle (1), in which process a foreseeable travel time duration and/or a foreseeable travel time end point are communicated to a control device (4) of the fuel cell system (2) at the beginning of a travel of the vehicle (1) or during the travel. The control device (4) operates the fuel cell system (2) such that a switch-off procedure for switching off the fuel cell system (2) is started so far ahead of the foreseeable end of the travel in time that the switch-off procedure will have been completed extensively simultaneously with the foreseeable end of the travel and the fuel cell system (2) is switched off.
Abstract: A depth-sensitive imager for imaging a scene in three dimensions. The depth-sensitive imager comprises a light source configured to project a polarized illumination onto a surface of the scene, and a detector configured to capture an image of the scene by detecting light from the scene, in which image a polarization state of the light is encoded. The detected light includes a portion of the polarized illumination reflected from the surface. The depth-sensitive imager further comprises an analyzer configured to generate output responsive to a distance between the light source and the surface based on the image.
Abstract: To improve PI performance of a mass flow controller, the mass flow controller changes a proportional coefficient, an integral coefficient, and a derivative coefficient used for PID operation in a stable state based on at least two out of a primary pressure, a time change amount of the primary pressure, and a flow rate set value.
Abstract: Systems, methods, and computer readable storage media are described in which exhaust gas is routed to a hydrocarbon retaining device during starting, and purged to the engine intake manifold. Various alternative approaches are described for controlling operation and diagnosing degradation. Further, various interrelated configurations are described.
