摘要:
A video conference system operates to identity and to determine a location of things in a conference room, and to determine an orientation of video conference participants towards the identified things, and uses an assigned priority of the things that the participants are oriented towards to automatically control a camera to focus on the highest priority thing.

An audio or video conferencing system having an array comprised of two or more microphones and having one or more loudspeakers positioned proximate to the microphones. The conferencing system also has acoustic echo cancellation (AEC) functionality that removes direct and reverberant acoustic echo from microphone signals in two separate acoustic echo cancellation operations. The first AEC operation removes direct acoustic echo prior to a beamforming operation, and the second AEC operation removes reverberant acoustic echo from a microphone signal subsequent to the beamforming operation.

A voice emitting and collecting device that is capable of picking up/outputting a voice emitted from a talker at a high S/N ratio by eliminating the influence of a diffracting voice despite a simple configuration is provided. A signal differencing circuit 191 outputs difference signals MS1 to MS4 between voice collecting beam signals MB11 to MB14 and voice collecting beam signals MB21 to MB24. A level comparator 195 selects the difference signal having a maximum level. A signal selecting circuit 196 selects voice collecting beam signals MB1x, MB2x of the difference signal MS that is selected/pointed by the level comparator 195. A subtracter 199 subtracts the voice collecting beam signal MB2x from the voice collecting beam signal MB1x, and output a resultant signal. Accordingly, main components of the diffracting voice can be removed from the voice collecting beam signal.

Respective orientations (a pitch angle, a roll angle, and a yaw angle) of the input device are detected based on angular velocity data outputted from a gyro sensor unit of an input device. Then, it is determined whether the pitch angle is within a first range or within a second range. When it has been determined that the pitch angle is within the first range, a posture of an object is updated based on the roll angle. When it has been determined that the pitch angle is within the second range, the posture of the object is updated based on the yaw angle. Accordingly, operability can be improved in a game executed in accordance with an orientation of the input device.

A liquid crystal display device including a liquid crystal panel provided with plural gate lines to select a pixel and plural data lines to supply pixel data and a data driver dividing a single frame into plural fields and converting frame data into field data to supply the field data to the data line is provided. When the frame data has a tone change, the data driver performs correction to data of an odd-number field of the frame in a same direction as an increase/decrease direction of the tone change of the frame data, and performs correction to data of an even-number field of the frame in an opposite direction to the increase/decrease direction of the tone change of the frame data.

An audio signal transmission/reception device includes a speaker array having a plurality of linearly arranged speaker units and a microphone apparatus having a microphone array having a plurality of linearly arranged microphone units. Some of the microphone units are aligned with equal spacing corresponding to a prescribed distance therebetween in a high-density alignment section, which is set symmetrical to an alignment origin corresponding to a center point of linear alignment. The remaining microphone units are aligned in a low-density alignment section externally of the high-density alignment section in such a way that the spacing therebetween is progressively widened integer times larger than the prescribed distance. Manufacturing costs can be reduced by reducing the total number of the microphone units, and it is possible to improve sound reception directivity with respect to both high and low frequency bands.

A thrombolytic composition containing tissue type plasminogen activator or a derivative thereof in combination with an anionic polymer or a salt thereof and an amine compound or a salt thereof or in combination with an anionic polymer or a salt thereof, an amine compound and an acid or a salt thereof. The composition is an aqueous solution or a lyophilized preparation which can be stably dissolved on dilution at near neutral pH in both pharmaceutical solutions having high salt concentrations, such as physiological saline, and pharmaceutical solutions having low salt concentrations, such as a 5% glucose solution. Clinically useful products for infusion or injection are prepared to be used at a pH near neutral.
