Abstract: A hands-free loudspeaker system which is capable of achieving high-quality voice amplification without requiring a human speaker to move to a microphone or a microphone to be moved to a human speaker. A microphone whose input level has continued to be above a threshold value for not shorter than a predetermined time period is detected, based on input signals from dispersedly arranged microphones. An input signal from the microphone is selected and outputted to each loudspeaker at an output level or with a delay time, according to a location of the loudspeaker. A preset lowest threshold level is initially set to the threshold value, and an input level of the microphone higher than the threshold value is newly set to the same, while when the input level is lower than the threshold value, a lower value is set to the same in a step-by-step manner.

Abstract: A tone generating system 100 has a motion detection terminal 11 and a tone producing device. The Motion detection terminal 11 has a motion sensor MS which is attached to the back of a hand, and transmitting unit 11a. The Motion sensor MS detects a torsional motion of the hand to which it is attached. The Transmitting unit 11a transmits motion information on the torsional motion. A Tone producing device 10 receives the motion information, generates control information based on the motion information, and produces a tone on the basis of the control information.

Abstract: On a casing of an electronic keyboard instrument, there are provided front speakers, rear speakers and upper speakers as non-front speakers, a woofer speaker, and a vibrator. Tone generator section generates tone signals of tone colors corresponding to tones of various musical instruments. Assignment section adjusts, on a tone-color-by-tone-color basis, tone volume allocations, of the generated tone signals, to the speakers and vibrator. Further, the thus-adjusted tone signals are mixed for each of speaker reproduction systems and vibrator drive system, and then the resultant mixed tone signals of the speaker reproduction systems and vibrator drive system are supplied to corresponding ones of the speakers and vibrator.

The engine control device includes: a main computer 1 to output a signal on the supposition that the predetermined fuel is used; and a sub computer 2 to calculate and output only an injection signal on the supposition that another fuel is used. The sub computer conducts injection control on another fuel according to the injection signal or ignition signal outputted from the main computer and further according to the output of a sensor. Control, except for injection control, is conducted according to a signal outputted from the main computer.

Abstract: As an electronic tone is generated in response to performing operation, the electronic tone is picked up by microphones corresponding to left and right channels, and picked-up sound signals thus generated by the microphones are then subjected to signal processing, such as reverberation impartment utilizing acoustic conditions of the interior of a room. Picked-up sound signals having undergone such signal processing are audibly reproduced via rear speakers. Then, once an automatic adjustment instruction is given from a user, measuring tones are reproduced stereophonically, and contents of the signal processing of the individual channels are adjusted on the basis of measured results of picked-up sound signals generated by the microphones picking up the reproduced measuring tones.

Abstract: As a vehicle runs, current load q(t) is calculated every given time. The current load q(t) can be calculated by multiplying the amount of air taken into an engine of the vehicle by the engine speed. Added-up load Q(t) can be found by adding up the current load q(t) according to expression of Q(t)=Q(t−1)+((q(t)−Q(t−1))/a). If the added-up load Q(t) exceeds an inhibition determination value Z, idling stop is inhibited, so that overheating of the engine can be prevented appropriately.
