A conveyor device for conveying an object with an identification device. The conveyor device comprises a plurality of rollers, connected drive motors for driving the rollers, a transmitter, a receiver for detecting the distance of the identification device and a control device for controlling the connected drive motors.

Conveyor device and method for conveying an object

An adapter for receiving at least one integrated circuit with a Hall sensor in a housing. The adapter has a cavity for receiving the at least one integrated circuit in the housing, at least one opening connected with the cavity, and a magnetic-field generating apparatus for generating a magnetic field in the cavity. The adapter is used in a system for detecting the strength of a magnetic field.

Adapter for receiving an integrated circuit

A measuring system and drive system with a measuring system, a magnet, a transmitter, and a magnetic field sensor. The magnetic field sensor is arranged between the magnet and the transmitter. The transmitter has a number of segments made of a magnetically conductive material, each segment having a wing shape with a web edge that is radially directed outwards, each web edge being diagonally designed towards the rotational direction, and that each web edge is distanced from the magnetic field sensor by an air gap.

Measuring system and drive system

A monitoring system having a monitoring unit and a circuit element that are integrated in an enclosure for protecting connections between the monitoring unit and the circuit element. The monitoring unit monitors the circuit element via a first electrical quantity, and the monitoring unit has a control unit and a first circuit unit and a second circuit unit. The first current is essentially or precisely equal in amplitude to the first current, and the first current and the second current flow simultaneously in the two line sections. The first current direction is opposite to the second current direction, and the first circuit unit ascertains a first voltage drop at the first line section, and the second circuit unit ascertains a second voltage drop at the second line section. The control unit ascertains the first electrical quantity from the first voltage drop and the second voltage drop.

Monitoring system

A magnetic field measuring device having a semiconductor body with a surface parallel to an x-y plane and having a magnet with a flat main extension surface parallel to the x-y plane, the direction of magnetization changes along the main extension surface due to at least two adjacent magnetic poles, the magnet being rotatable relative to the IC package about an axis of rotation extending in a z direction and the z direction being orthogonal to the x-y plane. An imaginary extension of the axis of rotation passes through the magnet. The semiconductor body has three magnetic field sensors spaced apart from one another on the surface, and each of the magnetic field sensors measures the same component of the magnetic field. All magnetic field sensors are located along the imaginary extension of the axis of rotation within the projection of the main extension surface.

A monitoring device is provided that includes a first line section with a first connection point and a second connection point spaced apart from the first connection point in the direction of the line, and with a control unit and with a first current sensing unit, having a current source. A first switch is inserted into the first connecting line and connects the first current source to the first connection point or disconnects it therefrom. In a first state the first switch is closed and the first current is impressed on the first line section and a first voltage determined by the amplitude of the actual current, and in a second state the first switch is open and a second voltage is determined, and the control unit is configured to ascertain the amplitude of the first actual current from the two voltages.

The invention relates to an apparatus for finding a parked vehicle again. According to the invention, a portable unit is provided with a pressure sensor whose signals can be evaluated by an evaluation and control unit in order to determine the current air pressure, with the evaluation and control unit evaluating the determined air pressure in order to determine altitude, and storing a first air pressure value as a reference value at a predeterminable first time, which reference value represents an instantaneous altitude of a geographic position of the parked vehicle, with the evaluation and control unit estimating a height difference between a current geographic position of the portable unit and the geographic position of the parked vehicle at a second time, and/or continuously from a pressure difference between the determined current air pressure value and the reference value.
