Patent number: 10240968Abstract: A differential measurement circuit (1) is implemented in a balance with electromagnetic force compensation. The circuit receives input from two photo currents (I1, I2) generated by photodiodes (D1, D2) and generates an output signal proportional to their difference. A switch (SW) controls the flow of current through a node (K?) to which the two photo currents are directed, by flipping between two states (zt1, zt2) within two phases (t1, t2) of a time period T. The switch is controlled so a reference current (IRef) from a voltage or current source (URef) is superimposed alternatingly within the time phases on one of the two photo currents which continuously flow into the node. The node lies at the input of an integrator (INT) whose integrator signal (sINT) can be compared in a comparator (CMP) to a cyclically recurring ramp signal (sRAMP) which conforms to the time period.Type: GrantFiled: February 16, 2017Date of Patent: March 26, 2019Assignee: Mettler-Toledo GmbHInventors: David Koller, Cyrill Bucher, Christoph Trautweiler

Patent number: 7569780Abstract: A force-measuring device (100) with at least one housing (20) has an interior space and at least one force-measuring cell (110) installed therein. At least one parameter characterizing an existing high-frequency electromagnetic field is determined by a sensor (50) arranged in the interior space or a sensor arranged outside of the housing, the sensor being adapted for detecting high-frequency electromagnetic fields. After an electromagnetic field is detected and compared to a threshold value, a response action of the force-measuring device is triggered if the detected parameter value exceeds the threshold value.Type: GrantFiled: October 30, 2007Date of Patent: August 4, 2009Assignee: Mettler-Toledo AGInventors: Hans-Peter Von Arb, Jean-Christophe Emery, Daniel Reber, Cyrill Bucher, Stefan Buehler, Hansruedi Kuenzi

Method of correcting the output signal of an analog amplifier, amplifier module and measuring device
Patent number: 7525375Abstract: A method is disclosed for correcting transfer errors of an analog amplifier that occur following a jump in the amplifier input signal caused by switching. A measuring device includes at least one sensor as well as a signal-processing unit connected to the sensor and analog amplifier. The signal-processing unit includes at least one modulator and/or a multiplexer, an analog amplifier and at least one processing stage following the analog amplifier in the circuit chain. The processing stage, dependent on the point in time when the switching jump occurs, is separated from the latter during a predetermined timeout phase duration by means of a switch that is arranged between the analog amplifier and the processing stage and is controlled by a timeout controller, and/or dependent on the point in time when the switching jump occurs, said processing stage is blocked by a timeout controller during a predetermined timeout phase duration.Type: GrantFiled: December 15, 2006Date of Patent: April 28, 2009Assignee: Mettler-Toledo AGInventors: Cyrill Bucher, Daniel Reber, Philip R.
