20100005879 | Apparatus for Capacitive Determining and/or Monitoring of Fill Level of a Medium - An apparatus for capacitive determining and/or monitoring of fill level of a medium in a container. The apparatus includes: A probe unit; a control unit, which supplies the probe unit with a drive signal; and an evaluating unit, which receives a response signal from the probe unit and which determines from the response signal a statement concerning fill level. Stored in the evaluating unit are at least a first and a second formula or a first and a second evaluating algorithm; and, in case accretion lies below a predetermined limit value, the evaluating unit determines the statement concerning fill level via a first formula and, in case accretion lies above the predetermined limit value, the evaluating unit determines the statement concerning fill level via a second formula. | 01-14-2010 |
20090109607 | Housing for an Electronic Device and Sealing Ring for a Housing - A housing comprises a first housing part, having a first bearing surface for a first contact surface of a sealing ring, and a second housing part, which can be screwed together with the first housing part and has a second bearing surface for a second contact surface of the sealing ring. The first contact surface of the sealing ring is produced from a first material having a first coefficient of friction in relation to the material of the first bearing surface, the second contact surface of the sealing ring is produced from a second material that has a second coefficient of fiction in relation to the material of the second bearing surface, and the first coefficient of friction is smaller than the second coefficient of friction. | 04-30-2009 |
