Abstract: Abnormality detection means 21 performs an abnormality determination when a power supply line 2 has the voltage lower than a reference power supply voltage VDD. If any abnormality is detected, the detection result is forwarded to sensor output compensation means 22, indicating a voltage decrease from the reference power supply voltage VDD. Based on the voltage decrease, the sensor output compensation means 22 accordingly compensates a voltage signal Vout coming from an acceleration sensor 1. Fall determination means 23 plots, on a time axis, the voltage output Vout of the acceleration sensor 1 after compensation made by the sensor output compensation means 22, and based on any change observed for the voltage output Vout on the time axis, makes a fall determination. In such a structure, a method and system for correct fall detection can be provided, without causing cost increase, through acceleration detection made properly despite any decrease observed for the power supply voltage of an acceleration sensor.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device capable of detecting a normal acceleration, without increasing the cost, even if an electric power source voltage for an acceleration sensor becomes low, and which is capable of accurately detecting falling-off conditions. SOLUTION: An abnormality detecting means 21 determines abnormality, when a voltage value in a power source line 2 becomes lower than a power source voltage VDD serving as a reference, and outputs a lowering quantity of the power source voltage, when the power source voltage VDD is used as the reference as information, to a sensor output correcting means 22, when an abnormality is detected. The sensor output correcting means 22 corrects a voltage signal Vout output from the acceleration sensor 1, in response to the lowering quantity of the power source voltage. A falling-off determining means 23 plots on the time axis the voltage output Vout of the acceleration sensor 1 corrected by the sensor output correcting means 22, and conducts determination of falling-off, based on the change in the voltage output Vout on the time axis.

Abstract: PURPOSE: To properly judge the detection of a battery capacity corresponding to the recording time or the reproducing time and to contrive elongation of a battery lasting time and also miniaturization and weight reduction of the equipment concerned. CONSTITUTION: A voltage of the battery 33 is fetched into a system controller 11, where judgement is performed as to whether a battery capacity is enough or not. At the time of judging the battery capacity, detecting width of the battery voltage is changed for the recording time and the reproducing time. Consequently, judgement as shortage of the capacity is prevented from happening for a battery which still has remained capacity at the recording time, due to an effect of a temporary drop of the battery voltage at the time of starting intermittent recording.

Abstract: PURPOSE: To reduce the power consumption and to contrive miniaturization and light weight of an optical disk player such as a minidisk player, etc. CONSTITUTION: Management information is recorded in a U-TOC area by moving an optical pickup 4 into the U-TOC area at the time of finishing or stopping recording. At this time, a switch circuit 41 is turned off, so as to cut off the supply of a power source to a circuit part concerning a sound signal processing, such as a conversion part 14, an encoder/decoder part 10, a RAM 12 and amplifiers 17, 22 and 23, etc. Thus, the power consumption at the time of writing the management information is reduced, and the overall power consumption is reduced, and then the miniaturization and weight reduction can be contrived.

Abstract: PURPOSE: To easily perform the mixing recording of high quality and long hours by mixing input sound signals from a plurality of lines and performing data compression and then recording. CONSTITUTION: An analog mixer 3 mixes an analog sound signal Ain supplied from input terminals 1, 2 and outputs it. An A/D converter 4 converts the output from the mixer 3 into a digital data. A sound compression encoder 5 performs encoding processing for compressing a data quantity. The sound data compressed by the encoder 5 is once written in a RAM 7 by a memory controller 6. The controller 6 reads out the sound data from the RAM 7 and supplies it to an EFM/CIRC encoder 8. The encoder 8 supplies the compressed sound data to a recording head 9 as a recording data. The recording head 9 records the sound data in a magneto-optical disk.
