Abstract: A deep fat fryer includes a controller operatively connected to a heating element for controlling the operation thereof to apply heat to a cooking chamber. A temperature sensor is disposed in the cooking chamber for measuring the temperature in the cooking chamber and communicating the same to the controller. The controller selectively operates the heating means to apply heat to the cooking chamber. Utilizing the output of the temperature sensor, the controller automatically determines whether the medium contained in the cooking chamber is water, liquid shortening or solid shortening or whether the cooking chamber is empty. Based on this determination, the controller takes appropriate action including, automatically adjusting its operation to conform to the detected medium.

Title: Process for integrating cordless telephone networks into cellular mobile telephone networks
Inventor: RAMS WOLFGANG
IPC: H04W88/06
Filed: 1997-04-30
Granted: 2008-02-05
Abstract: This invention concerns a process for integrating cordless telephone network s into cellular mobile phone networks by using dual--system terminals which support communication over both a cordless telephone network and a mobile phone network. In the process, the mobile phone network assigns each cordless telephone network usable by a specific subscriber an own LocationArea, to which a subscriber specific call number is allocated. A continuous check is made whether the subscriber is in the LocationArea of the cordless telephone network available to him, and if so, then any call incoming via the mobile phone network is completed optionally or automatically by a mobile phone switching center using the call number assigned to the LocationArea.

Granted: 2003-10-21
Abstract: An ink cartridge serving as a liquid container, comprises a liquid sensor having a piezoelectric element which detects a consumption state of the liquid contained in the container, and a consumption data memory as a memory means. The consumption data memory is a rewritable memory which stores consumption related data which are related to the detection of the consumption state using the liquid sensor. The consumption related data are, for example, consumption state data as a result of the detection. Even when the ink cartridge is removed, the consumption state data can still be utilized. The consumption related data may be a detection characteristic detected depending on the consumption state of the liquid. Based on this detection characteristic, the consumption state is detected utilizing the liquid sensor. The consumption state can be detected irrespective of individual differences of the ink cartridges.
