20090312846 | Apparatus for Detemining and/or Monitoring a Process Variable - An apparatus for determining and/or monitoring at least one process variable of a medium. The apparatus includes: at least one sensor unit for registering the process variable, wherein the sensor unit produces measurement signals; at least one electronics unit for controlling the sensor unit, wherein the electronics unit has at least one microprocessor; and at least one memory unit, which is associated with the sensor unit, and in which control data are storable. The control data specifically relate to the sensor unit and can be read out by the electronics unit. The microprocessor of the electronics unit is embodied in such a manner, that the microprocessor executes in an inactive state only basic functionalities, and that the microprocessor in an active state controls the sensor unit. The microprocessor transfers from the inactive state into the active state transfers by loading control data from the memory unit. | 12-17-2009 |
20100083750 | APPARATUS FOR ASCERTAINING AND/OR MONITORING A PROCESS VARIABLE OF A MEDIUM - An apparatus for ascertaining and/or monitoring of a process variable of a medium. The apparatus includes: A mechanically oscillatable unit; an exciting/receiving unit, which excites the mechanically oscillatable unit to execute mechanical oscillations and which receives the mechanical oscillations; and an electronics unit, which supplies the exciting/receiving unit with an electrical, output signal, and which receives from the exciting/receiving unit an electrical, input signal.

20100161251 | METHOD FOR DETERMINING AND/OR MONITORING A PROCESS VARIABLE OF A MEDIUM, AND CORRESPONDING APPARATUS - Method for determining and/or monitoring a process variable of a medium, wherein a mechanically oscillatable unit is supplied with an exciter signal wherein a received signal coming from the mechanically oscillatable unit is received, and wherein the exciter signal is produced in such a manner, that a phase difference between the exciter signal and the received signal equals a predeterminable phase value. A criterion for judging the determining of the phase difference between the exciter signal and the received signal, or a signal dependent on the exciter signal or on the received signal, is established; in the case, in which the criterion for judging the determining of the phase difference is fulfilled, tuning of the phase difference is closed-loop controlled; and, in the alternative case, tuning of the phase difference is open-loop controlled. An apparatus associated with the method is also disclosed. | 06-24-2010 |
20120324301 | METHOD FOR CHECKING THE FUNCTIONAL ABILITY OF A MEMORY ELEMENT - A method for checking the functional ability of a memory element having a stack memory, wherein the stack memory occupies a defined region within the memory element. A stack memory pointer is defined, which displays, in the form of an address, a stack memory position, from which data are currently being removed or to which data are currently being written. In the memory element, a section of defined length arranged outside a memory region to be checked is delimited and used as an auxiliary memory; the current address of the stack memory pointer is stored before the start of a test program for checking the memory element and the stack memory pointer is then assigned an address associated with the auxiliary memory, so that during the test program the auxiliary memory is used as working memory; and after terminating the test program the stack memory pointer is reassigned the address of that position, which it displayed before the start of the test program. | 12-20-2012 |
20130139585 | Device for Determining and/or Monitoring at least one Predetermined Fill Level - A device for determining a predetermined fill level of a liquid in a container, with a sensor unit, comprising a unit capable of oscillating mechanically, a transmitter unit, and a receiver unit, which is electrically and mechanically coupled to the transmitter unit, and which transduces the oscillation of the unit capable of oscillating into an electrical receiving signal. An electronic unit, comprising a regulating unit, which regulates a phase difference that exists between the electrical transmission signal and electrical receiving signal to a determined value at which the unit capable of oscillating conducts oscillations at a resonant frequency, and which forms an oscillation circuit with the transmitter unit, receiving unit and the unit capable of oscillating. The electronic unit comprises a compensation path with a compensation unit, which for compensating additional signal components in the receiving signal, which results from the mechanical and/or electrical coupling between transmitter unit and receiver unit, at least intermittently produces a compensation signal from the transmission signal and supplies this compensation signal to the receiving signal. The compensation unit produces the compensation signal in a way such that the compensation signal is opposite to the additional signal components in the receiving signal. | 06-06-2013 |
