Angular sensing for optimizing speaker listening experience
Audio speaker angular determination is made using sensor fusion technology involving an accelerometer, gyroscope, and magnetometer (compass). All speakers in an audio system use their magnetometers to determine their orientation relative to magnetic north.

The group owner determines the angle of orientation of all speakers relative to its own orientation. Changes in angular orientation are sensed by the gyroscopes. For example, during calibration, the user can be told to rotate a certain speaker in the system, and the gyroscope measures the change and reports to the group owner. An indication is presented as to whether the new angle is good, or more is required. The gyroscope in combination with the accelerometer senses changes of angular orientation to aim height speakers downward towards the listening position or bottom speakers upward. |

Innovations in flexible reference picture management are described.

Substrate transporter and substrate transport method
In a substrate transporter, a carry-in-and-out mechanism transports a substrate placed in a horizontal posture. A notch aligner rotates a substrate in a circumferential direction to change a circumferential position of a notch. The carry-in-and-out mechanism includes four supporters that oppose a lower surface of the peripheral portion of the substrate. In the substrate transporter, a controller controls the notch aligner on the basis of warpage-and-notch-position information and input information that is input about the warped state of the substrate, to determine the circumferential position of the notch of the substrate. Thus, the lower surface of the substrate placed on the transport mechanism comes into contact with the four supporters of the transport mechanism. As a result, it is possible to prevent or suppress the occurrence of rattling or misalignment of the substrate during transport by the transport mechanism, and enables stable transport of the substrate. |
