Abstract: In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This results in a poor signal-to-noise ratio owing the small signal and the large noise contribution by the switching transients. The invention proposes to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the switching point is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion in the case of digital audio signals.

Title: Dynamic laminating method and apparatus for ultrasonically bonding juxtaposed webs
IPC: B32B27/00
Filed: 1983-01-17
Granted: 1990-04-18
Abstract: A method and apparatus for bonding together a plurality of juxtaposed webs which are subject to being ultrasonically bonded together to form a laminate as the webs are being driven forward at a relatively high velocity. The regions of the webs to be bonded are subjected to progressively increasing compressive forces while simultaneously being subjected to ultrasonic energy as they traverse an elongate portion of a predetermined path at a predetermined velocity. After the regions are ultrasonically bonded they may be subjected to another compression prior to the bonds becoming fully set upon cooling. The method may be practiced in an apparatus which includes an ultrasonic horn and an anvil which are configured and disposed to define a bonding passageway having an elongate convergent portion; and the apparatus may include a pressure roll biased towards the anvil adjacent the downstream end of the passageway. In a preferred apparatus embodiment: the anvil is a power-rotated cylinder having a relief-type bonding pattern disposed on its circumferential surface, and the face of the ultrasonic hom is so curved in the machine direction that the passageway has a convergent-divergent arcuate shape; the entrance to the passageway is sufficiently high to obviate websplice induced jams; and the convergent portion of the passageway is preferably somewhat longer in the machine direction than the divergent portion.

Title: Ventilator with an electronically commutated d.c. motor
IPC: F04D25/06
Filed: 1983-11-16
Granted: 1987-04-15
Abstract: An electronically commutated, direct-current motor of a fan has, in a two-piece housing, a stator formed on one piece of the housing and a blade-equipped rotor attached to a shaft mounted in the housing. The rotor supports an odd number of diametrically opposed pairs of magnets which consist of permanent magnets with opposite poles. On the stator are mounted two coils positioned diametrically, a Hall element, and a diametrically positioned flux-conduction plate that faces the pole surfaces of the magnets of the rotor and is angularly offset from the coils. The Hall element senses the poles of the magnets passing by and generates an output voltage. In response to the Hall element output voltage, an electronic control circuit in the stator sends an excitation current to the coils for alternately attracting or repelling the magnets. The rotor's rotational direction is determined by the resting position of the magnets, as imposed by the flux-conduction plate associated with the coils. This fan has only a few components, is very flat, and runs very smoothly.

Granted: 1990-09-05
Abstract: A process for the perspective representation of objects on the picture screen of a numerically controlled machine tool is described in which the object is resolved into a series of sections which are represented successively with a given perspective offset. In order to avoid the representation of covered edges of these sections, the contours of the individual section surfaces are checked prior to being represented in order to determine whether or not they overlap a previously represented contour. This checking occurs through a simple coordinate comparison, taking into account the actual perspective shift between sections.
