A waterproof structure includes a housing, an electroacoustic transducer, a packing and an annular member. The electroacoustic transducer has a case formed with tone holes. The packing is interposed between the housing and the electroacoustic transducer and has a thin film part on a part opposed to the tone holes. The annular member is interposed between the thin film part and the case and surrounds the tone holes. A space surrounded by the thin film part, the annular member and the case is formed. The annular member is configured to bias the thin film part of the packing.

An audio signal processing device includes: a frequency-domain conversion unit that generates a plurality of pieces of frequency-domain information from a plurality of audio input signals acquired at different positions; a relative value calculation unit that calculates, for each piece of frequency-domain information, a relative value between a time-frequency component included in one frequency-domain information and a time-frequency component included in another frequency-domain information; a mask generation unit that compares the relative value with an emphasized range set based on a relative value threshold stored in advance to generate a time-frequency mask that decreases a value of the frequency-domain information corresponding to the relative value which is outside the emphasized range; a mask multiplication unit that multiplies the time-frequency mask by the frequency-domain information to generate emphasized frequency-domain information; and a time-domain conversion unit that converts the emphasized frequency-domain information into an audio output signal indicated as being time-domain information.

In a business wireless system, a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group. A transmission unit uses a channel assigned by the base station device to a first group for transmission. An authentication processing unit authenticates a user using the terminal device. A selection unit selects one of a second group that only the terminal devices for which the authentication process is completed can subscribe to, and the first group, when the authentication process is completed. When the second group is selected, the transmission unit the channel assigned by the base station device to the second group for transmission.

During standby (waiting time), a microcomputer of a portable radio device monitors positional information based on the RSSI level (received signal strength) of receiving standby signals and GPS data. Then, when it is detected, based on the positional information based on the RSSI level (received signal strength) and the GPS data, that the radio device has entered an area outside a radio communication enabled area, namely an out-of-service area, the microcomputer carries out a power save processing.
摘要:
An information reception apparatus which allows a user to easily understand, from an electronic program guide, the information announced in a broadcast program, and which contributes to increasing viewer ratings of the broadcast program. The information reception apparatus (broadcast reception apparatus) is provided with: an electronic program information acquisition unit (tuner, control unit) for acquiring electronic program information; an announcement information acquisition unit (control unit, DEMUX unit) for acquiring information announced in the broadcast program from information included in the electronic program information acquired by the electronic program information acquisition unit or from information transmitted together with the electronic program information; and an announcement information output unit (control unit, AV output unit) for outputting the electronic program information and for outputting information indicating the presence or absence of the announcement information, based on the information acquired by the announcement information acquisition unit.

A gimbal device includes a controller for controlling a gimbal mechanism to which an imaging device is fixed. The controller includes an angular velocity signal acquisition unit, a relative angle acquisition unit, and an angular velocity signal synthesizer. The angular velocity signal acquisition unit acquires first to third angular velocity signals. The relative angle acquisition unit acquires first and second relative angles. The angular velocity signal synthesizer generates from the first to third angular velocity signals and the first and second relative angles, first to third rotational shift angular velocity signals which are signals of a first rotational shift angular velocity about an axis parallel to a first correction axis, a second rotational shift angular velocity about an axis parallel to a second correction axis, and a third rotational shift angular velocity about an axis parallel to a third correction axis, respectively.
摘要:
Every frame regarding an input video signal is changed into a sequence of subframes. Subframe data is generated from the input video signal while first and second tables are alternately used. The first and second tables are designed so that a number of subframes assigned a pixel activated state increases each time a drive gradation related to the input video signal increases by 1. According to the first table, a subframe newly assigned the pixel activated state is one following the subframe or subframes which have already been assigned the pixel activated state when the drive gradation increases from an odd number to a next even number. According to the second table, a subframe newly assigned the pixel activated state is one preceding the pixel-activated-state subframe or subframes in that case. A display device is driven in response to the generated subframe data.
摘要:
A plurality of groups each including a plurality of terminal devices are formed, and each of a plurality of base station devices assigns a channel to each group to enable communication from one of the terminal devices included in the group to which the channel is assigned to another terminal device included in the group, and a receiving unit receives information on the number of terminal devices included in the groups registered in each base station device. A display unit displays information indicating the number of terminal devices for each base station device based on the received information.
摘要:
A first-temperature calculation unit calculates, as a first temperature, a maximum temperature within an image region captured by a far-infrared camera. A second-temperature acquisition unit acquires, as a second temperature, a surrounding temperature measured by a temperature sensor. An estimation unit estimates a surrounding environment on the basis of information on the second temperature acquired by the second-temperature acquisition unit and information on the first temperature calculated by the first-temperature calculation unit. A transmission unit transmits information on the surrounding environment estimated by the estimation unit.
