    摘要： A complete voice record and playback system capable of being powered by a single 1.8 VDC battery is operated in either stand-alone or CPU modes. In the stand-alone mode, two-button operation controls record, play, and memory erase functions. In CPU mode, commands may be provided through a serial interface which directly control record, playback, specialized memory management functions, and power amplifier gain settings. Through a serial interface, the system may be set up to directly write to external memory, using an analog signal generated by a microphone or other analog input device, or may instead be set up so that digital data provided by an external CPU and converted to analog using the on-chip D/A converter may be output by the speaker in real-time.

    摘要： A control program for controlling voice data processing by a computer causes the computer to selectively display a list display screen for displaying a list of file information concerning voice data of each file, and an operating screen, excluding the list of file information, for displaying an operating portion for performing voice data playback processing. The control program causes the computer to play back voice data of a file subsequent to a currently played-back file according to an order in the list displayed on the first screen, if a predetermined operation is executed on the second screen while the second screen is displayed.

    摘要： An analog memory unit that can be implemented, at least in part, on an application specific integrated circuit (ASIC) (12), utilizes at least the ASIC arithmetic logic unit (ALU) (24) to enhance performance and to generate and store an accurate measure of power line thermal status. The memory unit includes an analog-to-digital (A/D) converter (20) for converting an input analog signal from a parallel R-C circuit (14) to a digital signal and a scaler (22) for scaling the digital signal from the A/D converter to within a range acceptable for further processing. The ALU (24) receives input signals from the scaler and from a digital thermal memory (26). The input signal supplied to the ALU from the digital thermal memory is a four bit (digital) value proportional to the measured actual thermal status of the subject power line. The output of the ALU is connected to the input of latches (28) which latch, or store, the digital signal produced by the ALU. The ALU output signal is representative of the difference between charge on the R-C circuit and the most recently measured actual thermal status of the power line. The latches are connected to a digital-to-analog converter (30) which has its output connected to the input of the A/D converter (20) and to the R-C circuit (14).
