Abstract: A device is shown and described for controlling movable equipment (11) such as roller doors, shutters, rolling, scissors or lowering gratings, lowering windows, sound-absorbing hoods, furnace doors and the like, the tap of a potentiometer (22) being mechanically coupled as actual value transmitter to the drive (19) of the equipment (11) and simulates the respective position of the equipment (11) by means of an electrical value, having an electrical comparison device which compares the electrical value, associated with the respective position of the equipment, from the potentiometer with an electrical prescribed value, and having switching means for switching the electric motor on and off. The comparison device comprises a discontinuous three-point controller (27) which comprises at least three functional blocks, to be specific a first functional block (27A) which determines the control deviation, a second functional block (27C) which converts the control deviation into digital directional signals (A and Z) and a third functional block (27D) having an electronic switch which connects the first functional block (27A) to the second functional block (27C) only as long as a command instruction is present, otherwise the third functional block (27D) forms an internal reference signal for the second functional block (27C), which generates an apparent equivalence of the directional signals. By this means, a simple push-button control is made possible by means of only two push-buttons and, even when the push-buttons are open, the desired value is continuously available to the controller. <IMAGE>

Abstract: An MPEG audio/video decoder has memories, a signal processing unit (SPU) including a multiplier and a butterfly unit, a main CPU, and a memory controller which are time division multiplexed between decoding video and audio data. For audio decoding, the butterfly unit determines combinations of components of a frequency-domain vector to reduce the number of multiplies required to transform to the time domain (matrixing). Matrixing is interwoven with MPEG filtering to increases throughput of the decoder by increasing parallel use of the multiplier, the butterfly unit, and a memory controller. The decoder includes a degrouping circuit which performs two divisions in three clock cycles to degroup a subband code. Three cycles matches the write time of three components so that subband codes are degrouped and written to memory with a minimum delay. Performing two divides in three clock cycles allows the divider to be smaller. In response to an error signal from a source of an MPEG audio data stream, the decoder replaces data with an error code and temporarily enables error handling. The error code is a valid bit combination rarely found in MPEG audio data frames. During audio decoding with error handling enabled, the decoder checks for the error code and replaces the error code with reconstructed data. Typically, some subband data are replaced with zeros so that an error only changes some of the frequency components.

Abstract: A BPM or SRM electric motor (M) is supplied bus current. A PWM inverter (I) uses bus current to commutate the motor by systematically energizing and de-energizing the motor's windings (W) with the current. The resultant bus current waveshape has characteristics that are a function of a commutation angle between a rotor (T) of the machine and its windings. The waveshape includes the effects of bus ripple or transients. A commutation controller (10) samples the waveshape during each commutation interval to obtain commutation angle information. The controller provides control inputs to an inverter (I) to control commutation angle in response to the sample information. Commutation angle control includes calculating a control variable (I curve ) which is a function of commutation angle. This variable is comprised of sampled data values which are additively combined according to a prescribed formula and which provide a high degree of linearity over a wide range of commutation angles. The controller is further responsive to the motor's impulse response (H motor (t)) to reject bus ripple effects on the waveshape samples. By employing the control variable and impulse response, the controller provides appropriate frequency (f out ) and voltage (V out  corrected) inputs to the inverter to achieve an optimum commutation angle relationship between the rotor and windings.
