Abstract: A PWM inverter system having a sine (low-pass) filter (21). The sine filter (21) includes a reactor (25) and a capacitor (26), and is connected to the output of a PWM inverter. The instantaneous current (I c ) flowing through the capacitor (26), and the instantaneous output current (I L ) supplied from the sine filter (21) to a load are detected. An instantaneous voltage command value (V*) is corrected on the basis of the detected current values. This makes it possible to limit oscillating waveforms involved in the output voltage of the PWM inverter (1) without using a damping circuit (27) which was connected in parallel with the capacitor (26) in a conventional sine filter (23). The capacitor (26) of the sine filter (21) may be composed of a plurality of capacitors connected in parallel, and this will serve to further reduce the size of the sine filter. In a parallel operation of a plurality of PWM inverters, a cross current, that is, the difference between an instantaneous output current command value (I L ) and an instantaneous capacitor current command value (I c *) is reduced by correcting the instantaneous voltage command value (V*). This makes it possible to share the current assigned to each PWM inverter with high stability, and to limit a cross current flowing between the PWM inverters, thereby resulting in a stable parallel operation of the PWM inverters.

Abstract: A metabolic demand rate-responsive cardiac stimulation apparatus and method are disclosed which employ multiple physiological rate control parameters, such as respiratory minute volume, patient motion and cardiac stroke volume. The parameters are derived using a single standard pacing lead or transducer (11). The apparatus and method perform each physiological measurement by periodically applying a measuring current between two points within the apparatus. This measuring current has frequency components in a range of from approximately 10 kilohertz to 1000 megahertz. Application of this measuring current allows the apparatus to detect the voltage which arises from the applied current and, from the detected voltage, to measure the patient's spatial impedance. For a particular measurement, the apparatus controls which physiological parameter is sensed by regulating the frequency content of the measuring current. The apparatus analyzes the physiological parameters to determine the best pacing rate in terms of characteristics such as response time and stability.

Abstract: An optical interferometer and an ultrasonic distance measuring subsystem are used to obtain spectra from the surface of a sample. The interferometer uses a broadband electromagnetic radiation source and modulates the radiation at a frequency which is inversely proportional to wavelength. The modulated radiation impinges on the surface of interest where it is absorbed. The absorption of radiation causes the surface of the sample to expand. This change in dimension is then detected by the ultrasonic distance measuring subsystem which employs a single frequency acoustic radiation source to measure the instantaneous distance between the sample surface and the ultrasonic distance measurement subsystem. The detected changes in distance relate to amplitude of absorption at a given wavelength, thereby allowing absorption spectra for surface point to be generated indicating the chemical composition of each point of the surface.

Abstract: Radiation passing through a cone beam collimator is received by a radiation detector (10) such as a gamma camera head, as the gamma camera head is moved in a helical orbit. Data g(n,u,v) collected during the helical orbit is scaled (42) to scaled data G(n,u,v). A first partial derivative ∂G(n,u,v)/∂u is taken (46u) with respect to a horizontal direction and a second partial derivative ∂G(n,u,v)/∂v is taken (46v) with respect to a vertical direction. The partial derivatives are linearly combined (48) by being multiplied by sine and cosine values of an angle α between the horizontal direction u and an arbitrary direction p in the detector plane to form partial derivatives ∂G(n,u,v)/∂p. The coordinate system of the derivatives is converted (60) from the (n,u,v) coordinate system to an (n,α,p) coordinate system. The first derivatives are projected (62), i.e. summed row by row, onto a q axis which is perpendicular to the p arbitrary direction. The one-dimensional projection arrays are rebinned (70) to form first derivative Radon domain data R'(ϑ,ρ). A second derivative R''(ϑ, ρ) is taken (74) of the Radon domain data. The second derivative Radon domain data is backprojected (80) into an image memory (82) and displayed on a video monitor (84).

The intention is also to make retrofitting of a lorry which does not have rear axle steering possible at the lowest possible expense. In order to achieve this object, an actuator (31) which can be adjusted via a control element is required on the axle (1) to be deflected. <IMAGE>
