    摘要: A memory cell contains a memory transistor and a transfer transistor. A gate electrode of the transfer transistor and a control gate electrode of the memory transistor are connected to a word line. The memory transistor has a floating gate electrode that is isolated from a channel region of the memory transistor by a first dielectric layer and is connected to a first source/drain region of the transfer transistor. The control gate electrode is isolated from the floating gate electrode by a second dielectric layer. A first source/drain region of the memory transistor is connected to a bit line. The memory and transfer transistors are preferably of different conductivity types. During the writing of information, the transfer transistor is in the on-state and the memory transistor is in the off-state. During the reading-out of information, the transfer transistor is in the off-state and the memory transistor is in the on-state.

    摘要: In a method for operating a heatable exhaust-gas sensor, which supplies at least one measuring signal and in which a sensor heater is operated using a pulse-width modulated operating voltage, the detection of the at least one measuring signal has priority over the supply of the pulse-width modulated operating voltage for sensor heater, and at least during a predefined time window in which the measuring signal is detected, the supply of the pulse-width modulated operating voltage for the sensor heater is suppressed using a blocking signal.

    摘要: A light barrier detects an object which interrupts a beam of light of the light barrier. A light transmitter transmits a light beam in the direction of a reflector and a light receiver receives a reflected portion of the light beam. The improved light barrier has a reflector which is made as a cylindrical reflector column having a plurality of retroreflecting elements aligned toward the outer surface. The diameter of the reflector column is considerably smaller than the extent of the light beam perpendicular to the cylinder axis so that an optically effective detection beam of light is formed between the sensor and the reflector column whose cross-section at the sensor is determined by the light transmitter and, in direct proximity to the reflector column. The cross-section is determined by the areal overlap of the light beam with the reflector column.

    摘要: The invention relates to a light barrier for the detection of an object (2) which interrupts a beam of light (5) of the light barrier, having a sensor (4) with at least one light transmitter (4-1) for the transmission of a light beam (5) in the direction of a reflector (10); at least one light receiver (4-2) for the reception of a reflected portion of the light beam; and an evaluation unit (4-3) for the evaluation of the reflected light beam detected by the light receiver (4-2), To provide an improved light barrier which delivers an exact position determination of the object in the conveying device with a small installation and adjustment effort, it is proposed that the reflector (10) is made as a cylindrical reflector column (10) which has a plurality of retroreflecting elements (17) aligned toward the outer surface, with the diameter of the reflector column (10) being considerably smaller than the extent of the light beam (5) perpendicular to the cylinder axis so that an optically effective detection beam of light (20) is formed between the sensor (4) and the reflector column (10) whose cross-section at the sensor (4) is determined by the light transmitter (4-1) and, in direct proximity to the reflector column (10), by the areal overlap of the light beam (5) with the reflector column (10).
