Beyond this, it concerns a process for operating a motor vehicle near range radar with an all around view, comprising a number of individual radars (2, 2′) and a control unit (3, 3′) for controlling the individual radars (2, 2′), which process includes the following steps: operating the individual radars (2, 2′in a sensing mode as long as no contact vehicle (1, 1′) enters the range of the motor vehicle near range radar; and switching at least one individual radar (1, 1′) into a communication mode as soon as a contact vehicle (1, 1′) enters the range of the motor vehicle near range radar.
摘要:
A method and an arrangement for evaluating the combustion operations in an internal combustion engine with a model is suggested. The model takes a time-dependent transfer between pressure and structure-borne noise as a basis for the relevant low frequency oscillations and only individual components of the reconstructable pressure signal are used for the determination of combustion-relevant parameters and conditions. Independence of engine speed is achieved with the realization of the time dependency with an angular-dependent transfer function.

A fill system for use in a packaging machine is disclosed for filling a container with a primary and a secondary product. The fill system includes a primary pump system for pumping a predetermined amount of the primary product received at an inlet thereof. A primary fill pipe having an outlet overlying a container processing path along which the containers are filled and sealed by the packaging machine is connected to receive the predetermined amount of primary product from the outlet of the primary pump system. The fill system further includes a secondary pump system for pumping a predetermined amount of the secondary product received at an inlet thereof to an outlet thereof. A secondary fill pipe is connected to receive the predetermined amount of secondary product from the outlet of the secondary pump means. A valve mechanism is disposed, for example, concentrically within the secondary fill pipe and includes a sealing member positioned at the outlet of the secondary fill pipe. The valve mechanism is driven by a linear multi-stage actuator to provide multiple selected valve opening widths.

An electrically powered vehicle including an electric motor connected to drive a wheel of the vehicle. The electric motor receives a supply of electric current from a power source; a power electronics device and superordinated controller regulate the current supply based upon signals received from a driver or operator of the vehicle. A sensor for sensing data indicative of an accident or impending accident is connected to the superordinated controller in which the sensed data is compared to predetermined limit values to determine if an accident situation exists. Upon determining that an accident situation exists, the superordinated controller activates a circuit breaker to disconnect the electric power supply and thereby interrupt the supply of electric current to the electric motor.
摘要:
A fill system for use in a packaging machine is disclosed for filling a container with a primary and a secondary product. The fill system includes a primary pump system for pumping a predetermined amount of the primary product received at an inlet thereof to an outlet thereof. A primary fill pipe having an outlet overlying a container processing path along which the containers are filled and sealed by the packaging machine is connected to receive the predetermined amount of primary product from the outlet of the primary pump system. The container processing path lies generally perpendicular to the primary fill pipe. A nozzle is connected at the outlet of the fill pipe. The fill system further includes a secondary pump system for pumping a predetermined amount of the secondary product received at an inlet thereof to an outlet thereof. A secondary fill pipe is connected to receive the predetermined amount of secondary product from the outlet of the secondary pump means. The secondary fill pipe is concentrically disposed in the primary fill pipe and has an outlet that likewise overlies the container processing path. A valve mechanism is disposed, for example, concentrically within the secondary fill pipe and includes a sealing member positioned at the outlet of the secondary fill pipe. The sealing member is operable to control the flow of the secondary product from the secondary fill pipe. Operation of the fill system may be user controlled by a user interface and control system.

The drive arrangement for a motor vehicle includes an internal combustion engine (1) with at least one controlling element (29), an electric generator arrangement (3) driven by the internal combustion engine (1), at least one electric motor (11) which is powered by the generator arrangement (3) and drives the motor vehicle, and an electronic control unit (19) which, depending on the setting of an accelerator pedal (23), controls at least an actuating drive (27) and the electrical output generated by the generator arrangement (3) and/or the electrical output received by the electric motor (11). The arrangement contains a device for detecting an actual value of the speed of the internal combustion engine (1) and component for detecting an actual value of the electrical output generated by the generator arrangement (3). The control unit (19) has a speed regulating device (33) that maintains the actual speed at a given reference speed and an output regulating component (37) which maintains the actual electrical output at a given reference output. A data storage (31) in which performance data for combinations of data for the reference output with data for the reference speed and/or data for the adjustment of at least the actuating drive (27) are stored. In the event of dragging or motoring operation of the generator arrangement (3) and internal combustion engine (1), the control unit (19) detects the torque curve depending on the current of the generator arrangement (3) depending on the instantaneous angular position of the crankshaft and diagnoses operating errors and/or the state of the engine depending on the torque curve.

A drive and braking arrangement for a motor vehicle has at least one electric motor which drives the motor vehicle in dependence on the setting of an accelerator pedal. A forward drive or reverse drive selector (15) adjusts the driving direction of rotation of the electric motor, and a sensor is provided for detecting the driving speed of the motor vehicle. In order to control the braking force of a friction brake arrangement acting on at least one wheel of the motor vehicle, an actuating drive is provided which is set to a braking position by an electronic control unit when the accelerator pedal remains in a driving position for longer than a predetermined period of time and at the same time the detected driving speed is zero and/or when the sensor associated with the control unit detects an actual movement of the motor vehicle in the direction opposite to the driving direction selected at the selector.

The invention relates to a component (4) of a biosensor, comprising at least one first device (6) for receiving a sample liquid, wherein the device (6) is connected via a distributor channel (7) to further receiving devices (8 to 11), into each of which a feed channel (71, 72, 73, 74) branching off from the distributor channel (7) opens, and the feed channels (71, 72, 73, 74) are arranged in succession in flow direction (S) of the sample liquid passed on through the distributor channel (7). In accordance with the invention, it is envisaged that, in the distributor channel (7), in each case between two immediately successive feed channels (71, 72; 72, 73; 73, 74) in flow direction (S), at least one region (K) for at least temporary slowing or stoppage of the capillary flow of the sample liquid has been inserted. It is thus possible to control the capillary flow of the sample liquid such that always only one receiving device (8, 9, 10, 11) is filled with the volume flow of sample liquid available before the next is filled, and effectively simultaneous filling of the receiving devices (8, 9, 10, 11) is prevented. This leads to rapid and complete filling of the respective receiving device (8, 9, 10, 11). Additionally presented is a process with which the regions (K) can be inserted into the distributor channel (7) in a simple manner.
