Title: Pulse referenced control method for enhanced power amplification of a pulse modulated signal
Inventor: NIELSEN KARSTEN
IPC: H03F3/217
Filed: 1998-04-01
Granted: 2001-03-01
Abstract: To correct for any source of non-linearity and noise introduced in the power amplification of a pulse modulated signal, a correction unit is applied in-between the pulse modulator and the switching power amplification stage. The correction unit is controlled to have a compensating effect, by introducing continuous delays on the individual pulse edges on the basis of error information provided by an error processing block. One preferred embodiment of the invention comprises: a Correction Unit with means to control the delays of the individual pulse edges as a function of a control input signal Ve; a state feedback block A with compensation; a reference shaping block R to modify the pulsed reference vr for optimized error estimation; a difference block to generate an error signal and a compensator C to shape this error. The invention makes it possible to implement practical digital to analog power conversion, with efficient compensation of any non-linearity and noise introduced in the switching power stage and filter, such that great efficiency, high performance and low system complexity is combined. Applications are direct digital to audio power conversion and improved general DC-DC or DC-AC power conversion systems controlled from the digital domain.

Title: Linear predictive echo canceller integrated with relp vocoder
Inventor: WANG DAVID TZAT KIN
IPC: H04B3/23
Filed: 1987-09-01
Granted: 1989-08-24
Abstract: A linear predictive echo canceller is integrated with a RELP vocoder in a two-way communications network, in which a received digitized speech signal synthesized by the RELP vocoder from a residual signal received with linear prediction coefficients is echoed onto a transmit channel and combined with a transmitted digitized speech input signal that is to be analyzed by a RELP vocoder for transmission. The echo canceller cancels the echoed signal from the transmit channel by generating a foreground transmit signal by subtracting a foreground estimate of the echoed signal from the combined signal; and providing the foreground transmit signal on the transmit channel for ananlysis by the RELP vocoder. In order to generate the foreground transmit signal, the echo canceller filters the received digitized speech signal with adaptation coefficients to generate the foreground estimate of the echoed signal; prewhitens the foreground transmit signal by using the received linear prediction coefficients; and generates the adaptation coefficients by cross correlating the received residual signal with the prewhitened foreground transmit signal and adding the product of said cross correlation to the adaptation coefficients used for generating the foreground estimate of the echoed signal.

Title: Brake pad support plate with bent lug - produces warning sound when pad thickness is at minimum
IPC: F16D65/092
Filed: 1969-03-29
Abstract: A rectangular brake pad (11) for a disc brake is mounted on a support plate. One edge of the plate is forked to produce three lugs (9, 14, 15). The centre lug (9) is bent so that its edge (12) is embedded in the pad (11). The outer two lugs (14, 15) are tapered so that they produce an inclined face identical to the bent centre lug (9). When the brake pad is worn so much that edge (12) of the bent lug is in contact with the brake disc, the brake piston (2) rocks the pad assembly about edge (12). This produces a noise which indicates the required brake pad replacement.

Title: Printed cct. joint - reinforced joint of pin placed through conductor strip for additional mechanical and electrical strength
IPC: H05K3/34
Filed: 1971-11-05
Abstract: A soldered joint for making a connection to a timed conducting strip of a printed circuit, esp. one for high voltages or heavy currents, by applying a concentric ring of solder repellent varnish around the wire or pin before soldering, so that the molten solder is prevented from spreading and caused to assume a roughly hemispherical form around the wire, so increasing the mechanical strength of the joint. Around the varnish ring the tinned metal of the conducting strip is raised and tinned. The result of the annular raised strip so formed is to prevent the spreading of any hair crack which in the absence of the annular ring could affect the strength of the joint or its electrical continuity, with a possibility of arc formation.

Abstract: 1479005 Electronic musical instruments; teaching devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 24 June 1974 [23 June 1973] 28001/74 Headings G5J and G5X A musical signal system comprises a tone generator 26 actuated by a signal Sm from a memory device 24 such that any electrical audio frequency input signal S100 sensed by a sensor 22 as falling within predetermined frequency bands, each containing a note of a musical scale, is output as a more accurate representation of that note. The signal S100 may be derived from a human voice or musical instrument. The input bands may be abutting, separated or overlapping (e.g. Figs. 2, 12 and 13, respectively, not shown) and the outputs may be scale notes in the same input frequency bands or shifted therefrom by a predetermined multiple (Figs. 2 and 14 respectively, not shown) or may be a frequency lying in an output band which is narrower than the input band (Figs. 17, 19, not shown). When the input frequency bands overlap, two output frequencies may result and when the input bands are separated by a gap, no tone may be output if an input frequency is in the gap. The output may be controlled to provide vibrato or portamento as sensed at the input (Figs. 21, 22 respectively, not shown) or may be changed from one musical scale to another based on a different standard concept pitch (Fig. 20, not shown). The tone generator 26 may be suitably controlled separate oscillators (e.g. Figs. 3 and 5, not shown) or may be a controlled frequency divider coupled to a single oscillator (Figs. 9 and 10, not shown). The system may be used for teaching pitch accuracy.
