  • Patent number: 5640460
    Abstract: An amplitude adjust circuit (10) provides a scaled representation (36) of an analog audio signal (28) with substantially zero DC offset relative to a reference voltage. A voltage reference generator (12) produces a voltage reference (20) that inputs to an operational amplifier (14). The offsetting circuit (16) offsets an analog audio signal (28) by a DC component substantially equal to the voltage reference (20) and provides the result as an input to the operational amplifier (14). The operational amplifier (14) produces an output with a DC component substantially equal to the voltage reference (20). The impedance network (18) operably couples to the operational amplifier (14) output and to the voltage reference (20) so that both sides of the impedance network (18) are held at the voltage reference (20) level.

  • Patent number: 5638454
    Abstract: A system for reducing periodic noise, which includes a plurality of harmonically related noise signals, comprises an actuator for producing a canceling acoustic signal, a sensor for detecting a residual noise signal, a synchronizing signal generator and processing circuitry. The processing circuitry comprises a plurality of tunable harmonically related band pass filters, a tuning signal generator and a summer which sums the outputs of the filters. The tuning signal generator receives the synchronizing signal from the synchronizing signal generator and outputs the tuning signals to the band pass filters. As the frequency of the synchronizing signal changes, the tuning signal generator causes the tunable filters to track harmonics of the noise to be canceled. After summing by the summer and suitable amplification, the outputs from the filters are used to drive the actuator so as to reduce the residual noise detected by the sensor.

  • Patent number: 5574797
    Abstract: In the state of the art, it is known to connect diaphragms (11) of cone loudspeakers to the loudspeaker frame (10) by means of so-called beads (13). Such beads (13) are predominantly made of plastic or rubber, and are connected to the diaphragm (11) or the loudspeaker frame (10) by means of suitable adhesives. This type of connection limits the free selection of the above named components, because not all elastic bead materials can be connected to the diaphragm (11) with the required mechanical stability. The selection of materials is further restricted when the loudspeaker is subjected to ambient temperatures above C., because the adhesive connections lose their strength under such conditions. The invention has therefore the task of presenting a high-strength suspension mount for the diaphragms of cone loudspeakers. This task is fulfilled in that the bead (13) is made of an injection-moldable and high-temperature resistant elastomer material (e.g.

  • Patent number: 5534887
    Abstract: A display apparatus and method that provides a windowing interface that gives the user the capability to identify and locate the particular window associated with a bell tone emitted by an application program. When a particular application emits a bell tone, the system displays a locator icon on the display. The text associated with the locator icon contains the window title, which tells the user which window caused the tone to be emitted. To go directly to the window that issued the bell, the user positions the pointing device over the locator icon and activates it to bring the icon into focus. At this time the icon vanishes and the window that emitted the bell tone is prominently displayed so the user can attend to it. If the user does not activate the locator icon and no other bell tones are emitted from the same window, then the locator icon will be removed from the display after a time period, which may be set by the user.

  • Patent number: 5532716
    Abstract: A memory storing image data at a m1.times.n1 (horizontal to vertical) dot resolution is read out at a horizontal scanning rate corresponding to a first clock signal at a frequency f.sub.1. Data read out from the memory is latched in a first storage device in response to the first clock signal. An output from the first storage device is latched in a second storage device in response to a second clock signal at a frequency f.sub.2. The rate f.sub.2 is selected to be less than f.sub.1 and to correspond to the desired display rate of the display device having a pixel resolution of m2.times.n2. f.sub.1 and f.sub.2 are related such that f.sub.1 /f.sub.2 =(m1/m2). The difference in frequencies causes some of the X address from the memory to be dropped and not stored in the second storage device thereby resulting in the desired data conversion in the X direction. The Y address is incremented by an amount equal to n1/n2 to affect the resolution conversion in the Y direction.
