  • Patent number: 11495369
    Abstract: An electrical conductor has a first layer, wherein the first layer is electrically conducting, and has micro protrusions, macro protrusions, wherein the micro protrusions are arranged on the macro protrusions, a first set of depressions, wherein the first set of depressions comprises at least two longitudinal depressions; the macro protrusions and the at least two longitudinal depressions are arranged in an alternating pattern, at least one coating layer, wherein the at least one coating layer comprises an electrically conducting polymer, touches the first layer, at least partially covers the first layer; wherein at least 50% of the macro protrusions have a width, measured along a first direction in the range of 2.0 mm to 40.0 mm and at least 50% of the micro protrusions have a width, measured along the first direction, in the range of 0.001 mm to 1.000 mm.

  • Patent number: 6694123
    Abstract: A talking book and a method of authoring a talking book is presented where the talking book includes a synthesizer, an audio system, a memory, a display, and switches for selecting pages and/or chapters of the talking book. The talking book is authored by a script that lists speech files, the sampling rate, and the chapter and page boundaries. Configuration tables and segment tables are generated from the script and these tables are assembled with a playback program to combined binary data stored in the talking book.

  • Patent number: 6629279
    Abstract: A method of testing the performance of real time DSP algorithms after customer code has been added and includes the steps of embedding a signature equation in the DSP code that calculates to a given signature value at the output of the DSP when running a test mode program through the DSP.

  • Patent number: 6038536
    Abstract: A method is provided for compressing relatively time invariant binary data, such as speech data in a telephone answering device, using statistical analysis of changes in the data. An original record organized into multiple frames of multiple bits each is used to construct an XORed record of the same number of frames and bits. The XORed record has a base frame with the same bit value pattern as a corresponding base frame of the original record, and remaining frames with bit values given by the outputs of an exclusive-OR operation applied to the bit values of corresponding and prior frames of the original record. The bit positions of the XORed record frame set are analyzed and reordered, according to their bit value change activity and used to construct an output record. The output record may have a base frame with the same bit value pattern as the corresponding reordered XORed record base frame.
