The method includes binding living cells to magnetic particles, adding them to a sensor array, uniformly distributing over the sensor array, magnetically fixing the magnetic particles having the bound cells over the sensor array, and adding substances to maintain and/or improve the cell vitality to the sensory array, and/or adding substances to worsen the cell vitality to the sensor array. The assembly includes a sensor array composed of sensors, which are designed to be in direct fluidic contact with a fluid, and a device for generating a magnetic field over the sensor array. A layer that comprises magnetic particles and living cells is formed on the sensor array.

In a method or a device for forming an electric control signal for an injection impulse of a position-controlled fuel injector, particularly of a common-rail or pump-nozzle injection system, the course of the electric control signal can be selected freely in regard to the pulse edges (injection rate changes Q), the holding period (&#x394;t) and the injection rate (Q). This offers the advantage that the combustion process can be better optimized with respect to low emissions, low consumption and for meeting tightened legal regulations.

A method for injecting a fluid, in particular a fuel, performs the following steps: A nozzle () which can be actuated by a piezo element () is provided. A current pulse () is supplied to the piezo element (). The capacity () of the piezo element () is recorded at the time when the current pulse () is supplied. An actual characteristic curve of the injection is recorded based on the capacity (). The current pulse () is regulated in order to optimize the injection based on the actual characteristic curve of the injection.

A valve has a piezo actuator, a valve element, a valve body and a valve seat. At a predeterminable point in time, the valve element is controlled by a discharging process of the piezo actuator from a position in which it rests against the valve seat to a predetermined position located at a distance from the valve seat. The discharging process is divided into a first discharging period during which a predetermined first amount of electrical energy is discharged from the piezo actuator, a subsequent holding time period during which the piezo actuator is not controlled, and a subsequent second discharging period during which a predetermined second amount of electrical energy is discharged. The holding time duration and/or the first discharging period are/is adapted according to the course of a value that is not characteristic of the oscillation behavior of the piezo actuator during the holding time period.

An optical module has a circuit carrier, a housed semiconductor element placed on the circuit carrier, and a lens unit for projecting electromagnetic radiation onto the semiconductor element. The lens unit, which is constructed separate from the cased semiconductor element, preferably comprises a lens assembly formed of, for example, three lenses and of a diaphragm. The three lenses, optionally together with the diaphragm, are aligned in a well-defined manner due to their geometric design so that no additional optical adjustment is necessary. According to the invention, a support is formed, at least in sections, on the case of the semiconductor element, and the lens unit is placed thereon thus being supported. The concept is that by forming a support directly on the case of a cased semiconductor element even with classically cased semiconductor chips, it is possible to construct a camera module with which every mechanical focus setting can be eliminated. The novel system is particularly suited for use in the interior or exterior of a motor vehicle.

To optimize the results of rounding and therefore to optimize the high pressure resistance of the component, it is firstly proposed that prior to the machining step of hydro-erosive rounding, the edge () and the surfaces () of the high pressure-resistant component () which adjoin the edge () are each placed under compressive stresses in the region of their surface by means of a grinding and/or honing process. Also with regard to the method, and with regard to an apparatus for the hydro-erosive rounding, it is proposed that a closure element () is inserted into the continuing first bore (), downstream of the second bore (), which branches off from the first bore, as seen in the main direction of flow (S) of the liquid () mixed with abrasives (), in order to divert the liquid () mixed with abrasives () from the first bore () into the second bore ().

A method for controlling a piezoelectric actuator which displaces a control element of an injection valve includes the step of charging the actuator until a start voltage is reached. Subsequently, the actuator is discharged until a partial lifting voltage, which is maintained during a holding time, is reached. In the final step, the actuator is discharged until an off-load voltage is reached and a parameter which is dependent on the partial lifting voltage is used as a control variable. A desired value for the control variable is determined and the actuator is controlled in such a manner that the desired value of the control variable is maintained.

An optical module includes a lens arrangement which is used to project electromagnetic radiation to a semiconductor element and a light source disposed in the surrounding area of the radiation inlet area of the lens arrangement. The lens arrangement and the light source are provided with a covering which is permeable to electromagnetic radiation. The covering is provided with a radiation barrier that blocks the radiation which is emitted by the light source and prevents a direct injection of radiation which is emitted by the light source into the lens arrangement.

An optical module has a circuit carrier, a housed semiconductor element disposed on the circuit carrier, and a lens unit for projecting electromagnetic radiation onto the semiconductor element. The lens unit preferably includes a lens assembly with, say, three lenses and a diaphragm. The lenses, optionally together with the diaphragm, are aligned in a well-defined manner due to their geometric design so that no additional optical adjustment is necessary. The lenses are held in a type of lens holder that is an integral component of the housing of the semiconductor element.

A valve has a piezoelectric actuator with a valve element, a valve body and a valve seat. In order to control the valve, the valve element is moved into the valve seat from a position remote from the valve seat by means of a charging process at a prescribable first time. A first value is determined being characteristic of the electrical power supplied to the piezoelectric actuator when the valve element meets the valve seat. A second value is determined being characteristic of the electrical power supplied to the piezoelectric actuator when the charging process of the piezoelectric actuator is concluded. An actual difference value between the second value and the first value is determined. A difference between a setpoint difference value and the actual difference value is supplied to a controller. An actuating signal for charging the piezoelectric actuator is determined as a function of the actuating variable.

An optical module has a lens holder into which a lens array with three lenses and a diaphragm, for example, is inserted. The lenses and the diaphragm are oriented by way of the geometrical shape thereof such that no further optical adjustment is required. The circuit carrier and the lens unit are adjusted via at least one permanently flexible or springy element which is disposed between the lens holder and the circuit carrier and presses the component-equipped area of the circuit carrier away from the lens holder and against at least one stop element that is in positive contact with the lens unit. In the novel optical module or optical system it is no longer necessary to take into account the thickness tolerance of the circuit carrier and possible adhesives in the tolerance chain of optical modules. The module and the system are particularly suitable interior or exterior zone applications in motor vehicles.

A pressure sensor of a pressure-sensor module is connected to a wet space in a vehicle door by a through-passage channel of a sealing cushion and a connecting branch, which is guided with sealing action through a partition. A housing of the sensor module is located in a dry space. An interior of the housing and the dry space are sealed in relation to the interior of the connecting branch, with the result that a water-tightness of the housing, in which a printed circuit board and electronic components are accommodated, does not have to meet high requirements.
