Abstract: In a position measuring system for measuring the relative position of two objects, a scale having a graduation with a graduation period P is scanned by a scanning unit in order to generate a periodic analog signal having a bandwidth N. In order to generate harmonic-free Fourier coefficients of the fundamental wave of the periodic analog signal, a scanning plate included in the scanning unit includes a first scanning group with first and second scanning fields as well as a second scanning group with first and second scanning fields. The first scanning group is offset with respect to the second scanning group by P/4. The first scanning fields are offset with respect to the second scanning fields by P/2. Each scanning field includes N partial fields which are offset with respect to one another by P/2N in the measuring direction. The widths of the partial fields are varied in the measuring direction according to a sine function. To each scanning field there is allocated a scanning element, and the scanning elements of the second scanning fields are connected in difference of those of the first scanning fields. The scanning elements are connected to an evaluating arrangement for the formation of position measuring values.

Abstract: A digital-to-analog converter (DAC) converts digital input data into an analog output signal with less harmonic distortion over an entire signal-level range. An exponent value detector detects from the digital input data the number of bits by which the digital input data is to be shifted to form a mantissa part thereof. A digital shifter shifts the digital input data in accordance with the output of the exponent value detector, and outputs the mantissa part which is then supplied to a mantissa-part DAC. The mantissa-part DAC comprises an R-2R resistor ladder network and outputs the result of DA conversion of the mantissa part to an exponent-part DAC. The exponent DAC shifts the output of the mantissa-part DAC by an amount determined by the output of the exponent value detector, and outputs the shifted signal as the analog output signal of this DAC. A control circuit is provided between the digital shifter and the mantissa-part DAC, which prevents, in accordance with the output of the exponent value detector, the least significant bits of the mantissa-part DAC from operatively functioning to thereby decrease the number of operable bits thereof when the magnitude of the digital input data is small.

Abstract: High molecular weight polyanhydrides, defined as polyanhydrides having a molecular weight average greater than 20,000 or an intrinsic viscosity of greater than 0.3 dl/g in an organic solvent at room temperature, are formed by melt polycondensation of highly pure isolated prepolymers under optimized reaction conditions, particularly time and temperature with removal of the condensation product. Higher molecular weights are obtained by inclusion of a catalyst with the prepolymers in the melt polymerization. Catalysts used for transterification, ring opening polymerization and related polymerizations may be utilized. The high molecular weight polyanhydrides have improved physico-mechanical properties and are especially well suited for biomedical applications, particularly in controlled release devices for drug deliver.

Abstract: If in the case of a load (R1) powered by a battery (6) the detection means (10) detect a battery voltage below a first threshold value (V1) defined by an adjustable voltage source (20), first time-measurement means (40, 50) measure the time interval during which the load (R1) is powered by the battery (6), at a voltage below this threshold value (V1). If subsequently the load (R1) is switched off and not connected to the mains voltage via a power-supply circuit (1), the battery (6) is discharged by a discharger (30). Second time-measurement means (40, 60) measure the time interval during which the discharger (30) is operative until the detection means (10) detect a battery voltage below a second threshold value (V2), which is defined by a voltage source (25) and at which the battery (6) may be regarded as fully discharged drained. After comparison of the sum of the time intervals measured by the first and the second time-measurement means with the reference value, correction means (70) correct the first threshold value (V1) in such a way that during a next discharge the time measured is better in agreement with the reference value.
