Patent number: 7169600Abstract: The invention concerns an arrangement for determining the concentration of glucose in a tissue fluid. In the microdialysis technology used for this purpose, perfusate-containing glucose is transported in intermittent delivery pulses through a microdialysis probe inserted into the tissue fluid and dialysate obtained in this process is passed to a measuring cell to record the glucose content. In order to achieve an exact determination of glucose even with a reduced dialysis period, it is proposed that the starting content of glucose in the perfusate is adapted to the glucose content of the tissue fluid by means of a control device in accordance with a command variable derived from the measurement signals of the measuring cell. When the control deviation is negligible the momentary starting content of glucose in the perfusate can be determined as a measure for the glucose content of the tissue fluid.Type: GrantFiled: February 19, 2004Date of Patent: January 30, 2007Assignee: Roche Diagnostics GmbHInventors: Udo Hoss, Hans-Joerg Pfleiderer, Ralf Gessler, Hans-Ulrich Zieten, Rolf Fussgaenger

Patent number: 5170375Abstract: A static memory is constructed in a plurality of hierarchy levels. Beneficial realization possibilities are set forth with respect to the surface utilization for the drive and read-out circuits in the second hierarchy level which are especially critical. Memory cells that supply a strong cell signal are advantageously utilized so that a low expense is needed in the read circuit. By displacing periphery circuits into higher hierarchy levels, a short access time and a reduced surface requirement arise.Type: GrantFiled: September 18, 1991Date of Patent: December 8, 1992Assignee: Siemens AktiengesellschaftInventors: Hans-Juergen Mattausch, Bernhard Hoppe, Gerd Neuendorf, Doris Schmitt-Landsiedel, Hans-Joerg Pfleiderer, Maria Wurm

Patent number: 5040146Abstract: Memory cells are disclosed that avoid the utilization of analog circuits in the memory peripheral circuits when they are utilized in static memory modules and that intended to enhance the disturbed reliability when confronted by technology modifications and parameter fluctuations. Write-in thereby occurs from a write data line via a write selection transistor and read-out occurs via a read selection transistor onto a read data line. A second inverter formed of two field effect transistors serves as a feedback element in order to statically maintain the cell information. Due to an implemented asymmetry in the dimensioning between the first and second inverters, the memory cell is significantly less susceptible to information loss upon read-out when compared to a heretofore known memory cell. A precharging of the read data line is not required with these memory cells.Type: GrantFiled: March 9, 1990Date of Patent: August 13, 1991Assignee: Siemens AktiengesellschaftInventors: Hans-Juergen Mattausch, Bernhard Hoppe, Gerd Neuendorf, Doris Schmitt-Landsiedel, Hans-Joerg Pfleiderer, Maria Wurm

Patent number: 4959621Abstract: A differential amplifier having externally controllable power consumption. The differential amplifier has an external circuit stage for signal-dependent setting of the power consumption. The circuit stage is composed of two field effect transistors connected parallel to one another that are arranged in series with a resistor of the output side via which the current source of the differential amplifier is set. The field effect transistors are driven by a level-converting circuit proceeding from the amplifier input, this level-converting circuit being equipped with a control circuit. The control circuit defines the operating points of the field effect transistors with and without applied input signal and thus controls the signal-dependent boosting of the amplifier current.Type: GrantFiled: June 16, 1989Date of Patent: September 25, 1990Assignee: Siemens AktiengesellschaftInventors: Bedrich Hosticka, Roland Klinke, Hans-Joerg Pfleiderer

Patent number: 4956613Abstract: A differential amplifier having externally controllable power consumption. Differential amplifiers have a "static-bias" stage for setting the quiescent currents that flow in parallel circuit branches. Two field effect transistors that are connected parallel to one another are in series with an output resistor of this stage, these field effect transistors being driven via a level-converting circuit given the appearance of an input signal to be amplified, such that a voltage boost occurs at the output resistor. This voltage boost leads to a current boost in the differential amplifier. Good driver properties, a distortion-free signal transmission and a low dissipated power are provided by this external control of the two field effect transistors that results from the amplifier inputs.Type: GrantFiled: June 16, 1989Date of Patent: September 11, 1990Assignee: Siemens AktiengesellschaftInventors: Bedrich Hosticka, Roland Klinke, Hans-Joerg Pfleiderer

Patent number: 4843341Abstract: The differential amplifier has two n-channel or p-channel field effect transistors serving as controllable current sources which supply auxiliary currents upon appearance of an input signal which amplify the quiescent current. The inputs of the differential amplifier are connected to the gate terminals of the n-channel or p-channel field effect transistors via a level-converting circuit for converting the d.c. component of the input signal superimposed on a gate bias voltage to a lower or, respectively, higher output level. As a result of the control of the current sources proceeding from the amplifier input good driver qualities, a distortion-free signal transmission and a lower dissipation power are guaranteed.Type: GrantFiled: December 24, 1987Date of Patent: June 27, 1989Assignee: Siemens AktiengesellschaftInventors: Bedrich J.

Patent number: 4517672Abstract: A function check of a programmable logic array is performed in which input lines, product term lines and ground lines are combined into an AND plane and output lines, product term lines and ground lines are combined into an OR plane. The aim is a simple method of function check which permits any potentially-existing fault to be detected. The check is achieved by generating, with a test data generator, bit patterns and applying the same to the input lines, and, through the use of a shift register, successively sensitizing the product term lines either individually or in groups, i.e. disconnecting the same from ground potential. The bit patterns occurring at the output lines are supplied to a test data evaluator. The area of use is in logic circuitry of data processing technology.Type: GrantFiled: July 23, 1982Date of Patent: May 14, 1985Assignee: Siemens AktiengesellschaftInventors: Hans-Joerg Pfleiderer, Gerhard Grassl

Patent number: 4496980Abstract: A two-dimensional image sensor integrated on a semiconductor substrate has a plurality of sensor elements disposed in rows and columns. The sensors in each row and column are individually selected in succession via parallel outputs of a vertical shift register for readout of the sensor elements. Regulation of the integration time during which charge carriers collect in the sensor elements due to incident light is achieved by selecting the sensor elements in each even-numbered row for readout a further number of times after an initial readout of the charges optically generated therein, and within the time span during which transfer of the charges from the sensor elements of the next odd-numbered rows to the column lines takes place. The further selections eliminate charges formed in the interim in a particular row.Type: GrantFiled: August 19, 1982Date of Patent: January 29, 1985Assignee: Siemens AktiengesellschaftInventors: Hans-Joerg Pfleiderer, Heiner Herbst

Patent number: 4370724Abstract: A circuit for sensor controlled distance measurement is disclosed having two linear image sensors which are positioned to receive corresponding lines of two images derived from an object. The sensor signals are subjected to correlation measurements from which the distance of the object is determined. In the case of circuits of this sort, one endeavors to attain as exact and unfalsified a distance measurement as possible. For this purpose, the sensor signals are digitalized in evaluators, then read via transfer transistors into shift registers which undertake relative position displacements of the sensor signals in a longitudinal direction of the image sensors between individual signal cycles, and are subject to a correlation measurement. The circuit distinguishes itself in that the digital evaluation proceeds completely independently of parameters of the shift register and is thus carried out very precisely. Applications include photographic and electronic cameras.Type: GrantFiled: July 24, 1980Date of Patent: January 25, 1983Assignee: Siemens AktiengesellschaftInventors: Heiner Herbst, Hans-Joerg Pfleiderer, Hans-Peter Grassl

Patent number: 4367534Abstract: A circuit for sensor-controlled telemetry has two linear image sensors each having a number of opto-electronic sensor elements on which are projected sections of corresponding lines of two separately-obtained images from an object whose range is to be determined and has a single-input evaluator post connected to each sensor element through switching transistors, which evaluators are switchable between two logic states dependent upon whether a voltage generated by accumulated charge in a sensor element is above or below a reference potential. The digitalized signals from each evaluator are serially transmitted through respective associated shift registers to a logic circuit which compares the contents of stages of shift registers for each image sensor for determining coincidence of the digital signals.Type: GrantFiled: July 24, 1980Date of Patent: January 4, 1983Assignee: Siemens AktiengesellschaftInventors: Heiner Herbst, Hans-Joerg Pfleiderer, Hans-Peter Grassl
