Abstract: A utility vehicle trailer having a vehicle electrical distribution system. The vehicle electrical distribution system includes a control unit having a first voltage transformer device. The electrical energy for operating at least one consumer connected to the control unit in a first operating state of the control unit is provided via an energy supply connection, via which the vehicle electrical distribution system is connected, at least in the first operating state, to an electrical energy source of an electronic braking system of the utility vehicle trailer. Electrical energy for operating the at least consumer in a second operating state of the control unit is provided by an electrical energy store of the utility vehicle trailer. The first voltage transformer device is configured to decouple a first ground potential connected to the energy supply connection from a second ground potential connected to the electrical energy store of the utility vehicle trailer.

Abstract: The present invention relates to a process for obtaining a system for the controlled delivery of a biologically active substance allowing to obtain an effective delivery in terms of percentage of said biologically active substance that is absorbed by the organism. More particularly, the present invention relates to a process consisting in obtaining a controlled delivery system in which the biologically active substance is enclosed in a structure having a substantially parallelepiped shape with the desired shape and size, which can internally adapt to the biologically active substance to be carried and externally to the interaction with target cells (for example, enterocytes), thus optimizing the delivery modes of said biologically active substance.

Abstract: A sensor array made up of 2n piezoelectric oscillators (preferably paired quartz oscillators) is provided in which n equals the number of axes of interest and each one of the pairs of oscillators has a principle axis directed oppositely from the other of its pair. A controller which preferably includes a microprocessor, makes use of the dynamic relationships of the sensors in the array to adaptively assess the magnitude of weighting factors needed to correct the output signal from each oscillator for environmental and systematic effects to provide optimum frequency and phase output for computing position, velocity, and acceleration. Preferably, a seventh reference oscillator is provided in the center of the array which is canted relative to each of the three orthogonal axes by 45°. This adaptive sensor array is capable of determining position within one meter along any of the x, y, and z axes without the need for any external (e.g., GPS) signal.

Abstract: A method and apparatus for obtaining an accurate measure of the frequency of an applied signal by generating a pair of independent frequency signals wherein one of the independent frequency signals has a frequency value which is indicative of the operating temperature of the counter. The counter has two modes of operation: a calibration mode and a measurement mode. In the calibration mode, an accurate signal having a preselected frequency value is applied to the counter. The frequency of this signal is measured with reference to the other of the pair of independent frequency signals and this measured value is then algebraically combined with a prestored value that is equivalent to the preselected frequency of the applied signals. The combined value represents the necessary normalized correction factor for any measured frequency when the counter is at the corresponding temperature.

Abstract: A method and apparatus utilizing a quartz crystal resonator with an orientation substantially equal to (yxwl) 21.93.degree./33.93.degree. vibrating simultaneously in two thickness modes to provide a stable frequency signal source. By combining a quartz crystal resonator of the above type with either digital or analog compensation, the frequency-temperature deviation of one of the crystal mode frequencies is used as an internal thermometer and the second crystal mode frequency as a reference frequency signal. The frequency signal for the thermometer function is utilized by the compensation network to stabilize the frequency of the reference signal. Additionally, the analog or digital compensation is accomplished by means of either a curve-fitting routine or an interpolation look-up table routine.

By combining a quartz crystal resonator of the above type with either digital or analog compensation, the frequency-temperature deviation of one of the crystal mode frequencies is used as an internal thermometer and the second crystal mode frequency as a reference frequency signal. The frequency signal for the thermometer function is utilized by the compensation network to correct the measurements made with, or to stabilize, the frequency of the reference frequency signal. Additionally, the analog or digital compensation is accomplished by means of either a curve-fitting routine or an interpolation look-up table routine.
