20090103748 | Sound Generating Apparatus - An object is to enhance workability in attachment in a sound generating apparatus that generates sound by vibrating a vibration plate with a vibrator while ensuring acoustic performance as good as that achieved by fastening with fine screw threads. Workability in attaching operation is improved while ensuring acoustic performance as good as that provided by fastening with fine screw threads, by providing first fixing means that brings engagement portions | 04-23-2009 |
20110255730 | SPEAKER DEVICE - A speaker device having a speaker section firmly fixed to a stand section so the orientation of the speaker section relative to the stand section can be easily adjusted. The speaker device includes a speaker section, a stand section, and a fastening section for fastening the speaker section and the stand section to each other. The speaker section includes an engaging groove section, and a curved, contact receiving section which allows the angle of the speaker section relative to the stand section to be adjusted. The fastening section includes an engaging section engaging with the engaging groove section, and a screw thread section connected to the engaging section and engaging with a screw thread hole formed in the stand section. The fixation of the speaker section to the stand section can be adjusted by rotating the screw thread section to engage the screw thread section with the hole. | 10-20-2011 |
20110261991 | SPEAKER DEVICE - A speaker device, wherein vibration of a magnetic circuit section is suppressed with a magnetic influence on the magnetic circuit section suppressed. A speaker device having a vibration section and generating an audio sound by vibration of the vibration section is provided with a magnetic section for forming a magnetic field for vibrating the vibration section and also with a weight section fixed to the magnetic circuit section and suppressing vibration of the magnetic circuit section subjected to reaction force caused by vibration of the vibration section. The weight section is fixed to the magnetic circuit section through a joint section for joining the magnetic circuit section and the weight section to each other, and this forms between the magnetic circuit section and the weight section a predetermined space for magnetically separating the magnetic circuit section and the weight section from each other. | 10-27-2011 |

20100033366 | RADAR APPARATUS AND CONTROL METHOD OF THE SAME - A radar apparatus is provided. An antenna is configured to transmit a frequency-modulated transmission wave toward an object and receive a reception wave from the object. A mixer is configured to mix the transmission wave with the reception wave to generate a beat signal having a first beat interval and a second beat interval. A detecting section is configured to detect a plurality of first peak signals contained in the first beat interval of the beat signal and a plurality of second peak signals contained in the second beat interval. A grouping section is configured to group the second peak signals. A searching section is configured to search a part of the first peak signals corresponding to the grouped second peak signals. A separating section is configured to separate the part of the first peak signals from the other part of the first peak signals. | 02-11-2010 |
20110074622 | SIGNAL PROCESSING APPARATUS, RADAR APPARATUS, OBJECT DETECTION SYSTEM, SIGNAL PROCESSING METHOD, AND COMPUTER-READABLE MEDIUM - A signal processing apparatus performs an object detection process of detecting object data with respect to peak signals which indicate a difference in frequency between a transmitted signal of which the frequency is changed in a predetermined period and a received signal which is obtained by receiving a reflected wave that corresponds to a transmitted wave which is based on the transmitted signal and is reflected from an object, by deriving the peak signals in a first period where the frequency of the transmitted signal ascends and in a second period where the frequency of the transmitted signal descends and by pairing the peak signals in the first period and the second period. A continuity determination section determines a continuity between the object data and past object data detected prior to the object data. A moving objection data detection section detects newly detected moving object data that has no continuity with the past object data among the object data as a result of continuity determination by the continuity determination section. A position relationship detection section detects a position relationship between the moving object data and other object data. A data determination section re-pairs the moving object data if one object data among the other object data has a predetermined position relationship with the moving object data. | 03-31-2011 |
20110205102 | RADAR DEVICE, OBJECT DETECTION SYSTEM, AND OBJECT DETECTION METHOD - A vehicle mounted radar device operable to scan a transmission wave to detect a detection point representing a position of an object disposed around the vehicle on the basis of a reflected wave of the transmission wave from the object. The radar device includes a reading unit, a continuity determination unit, a setting unit, anti an object determination unit that are configured to prevent the radar device from erroneously determining different pieces of object information as a single object. | 08-25-2011 |

20130249731 | RADAR APPARATUS AND TARGET DETECTING METHOD - A radar apparatus includes a retrieval unit, an estimation unit, a calculation unit, and a determination unit. The retrieval unit retrieves a strong reflection object based on a signal strength which a frequency spectrum of a beat signal generated by mixing a transmission signal which is frequency-modulated and emitted and a reception signal which is formed in the transmission signal is reflected on a target indicates. The estimation unit estimates an estimation orientation which is an orientation of a target assumed to be present around the strong reflection object, based on a relative distance to the strong reflection object. The calculation unit calculates power which is the signal strength for the estimation orientation by generating an orientation spectrum in the estimation orientation based on a frequency component corresponding to the relative distance. The determination unit determines whether there is the target in the estimation orientation based on the power. | 09-26-2013 |
