A wideband signal is enhanced or suppressed to the same extent at each frequency without increasing the size of an overall sensor array. To achieve this, there is provided a signal processing apparatus including a direction estimator that obtains a direction of arrival of a signal for signals received from a plurality of sensors and each containing a target signal and noise, a first gain calculator that calculates a first gain using the direction of arrival of the signal, an integrator that obtains an integrated signal by integrating the signals received from the plurality of sensors, and a multiplier that multiplies the first gain by the integrated signal.

The present invention achieves a balanced discharging in a power storage system having a plurality of storage batteries connected in parallel. A power storage system comprises a plurality of storage batteries 100a-100f connected in parallel, a storage battery device 120 at least setting an output voltage value at discharge to each of the plurality of storage batteries 100a-100f. The storage battery device 120 includes a discharge control circuit 121 configured to assign at least one storage battery of the plurality of storage batteries for a master based on at least a battery residual capacity or a battery voltage and set the output voltage value so that the output voltage value differs between the master and the storage battery.

A tape attaching apparatus includes: a chamber having an airtight space formed therein; a rubber sheet that partitions the airtight space into first and second airtight spaces and has an upper sheet on which a wafer is placed; a tape frame that holds a tape above the rubber sheet; and first and second supply/exhaust tubes that switch pressurization and depressurization of the first and second airtight spaces. In pressurizing the second airtight space and expanding the rubber sheet to lift the wafer to be attached to the tape, after bringing the first and second airtight spaces into a vacuum state, the wafer is attached to the tape while an amount of pressurization of the second airtight space is controlled to change an expansion rate of the rubber sheet from a low speed to a high speed stepwisely.

In an order shop system, a shopping mall is constituted of a body capture booth located at a center and a group of shops of different kinds located around the body capture booth. The body capture booth and the group of shops are connected by an Internet having a data center functioning as a server. The body capture booth is configured to measure the shape data of a body of an entering customer and to transmit the shape data of the body of the customer thus measured to the data center. Each of the shops of different kinds is configured to receive an order of a goods or services from the customer whose body shape data was measured in the body capture booth, and to obtain the body shape data of the customer from the data center and to actually supply the ordered goods or services prepared on the basis of the body shape data of the customer.

There is provided a signal processing apparatus that obtains a speech signal with sufficiently reduced wind noise. The signal processing apparatus includes a main microphone that is provided so as to be readily influenced by movement of air outside the signal processing apparatus, a sub microphone that is provided so as to be hardly influenced by movement of air outside the signal processing apparatus, a determiner that determines, based on a strength of a main speech signal output from the main microphone, whether the main speech signal includes a predetermined amount of wind noise, and a selector that receives the main speech signal and a sub speech signal output from the sub microphone, executes, if it is determined that the main speech signal includes the predetermined amount of wind noise, selection processing for outputting the sub speech signal, and executes, if it is determined that the main speech signal includes no predetermined amount of wind noise, selection processing for outputting the main speech signal.
摘要:
In response to changes in an input binary digital signal, a 3rd order cosine pulse waveform, which, when it is changed in the increasing direction, has null0null level in a first period of T/12 (T corresponding to one-half cycle of the binary digital signal), is changed as a waveform of (h/2)(1nullcos (3nullt/T)nullnull/4) in the next period of 4T/12 (null5T/12nulltnullnullT/12) and has an h (constant) level in the remaining period of T/12, and when it is changed in the reducing direction, has the h level in the first period of T/12, is changed as a waveform of (h/2)(1nullcos(3nullt/T)nullnull/4) in the next period of 4T/12 (T/12nulltnull5T/12) and also has null0null level in the remaining period of T/12. By using this pulse wave, a flat part is generated in a time width of T/12 with respect to a judgment point. It is thus possible to improve the immunity to the effects of digital signal jitter, obtain change judgment with a sole single pulse and reduce the circuit scale and the power consumption.
