Patent number: 8131457Abstract: A navigation terminal device includes a map information display unit 771, a destination display unit 773, a route line drawing unit 774 for holding retrieved location information or destination information or both of them and drawing a route from a reference point based on the retrieved information or destination information to the destination or the retrieved location information so as to be superimposed on the screen with the map information displayed thereon, and route searching unit 775 for exchanging the display between the reference point and the destination if the reference point disappears from the screen when the destination is displayed, thereby permitting to follow the route from the displayed reference point to the destination or from the destination to the reference point. In this configuration, the operability of a terminal device having a small capacity of screen can be improved and the burden for the user can be relaxed.Type: GrantFiled: December 17, 2007Date of Patent: March 6, 2012Assignees: Pioneer Corporation, Increment P CorporationInventors: Satoshi Kumada, Toshie Shirahama

Patent number: 6519344Abstract: There is provided an audio system which suppresses standing waves. An audio signal source (1) outputs audio signals (SR) and (SL) which are then supplied to reproducing loudspeakers (3) and (4),installed in a room (2), where the reproduced sounds are outputted. Furthermore, the audio signals (SR) and (SL) are added at an adder (9) to obtain signal (S2) which is in turn filtered by a compensating filter and then inverted by means of an inverting circuit (13). This generates a compensation signal (Sc) with a phase opposite to that of the standing wave. The compensation signal (Sc) is supplied to a compensating loudspeaker (5) installed in the room (2), whereby sound for canceling out the standing wave is outputted. The compensating filter has its frequency characteristics set in accordance with the cross-correlation function between a transfer function from the reproducing loudspeakers, (3) and (4), to a listening location and a transfer function from the compensating loudspeaker (5) to the listening location.Type: GrantFiled: September 29, 1999Date of Patent: February 11, 2003Assignee: Pioneer CorporationInventors: Kiyoshi Yajima, Satoshi Kumada

Patent number: 6477255Abstract: A rear speaker and a front speaker are provided in a room. A microphone is disposed at a listening position between the front and rear speakers for picking up a first sound from the front speakers and a second sound from the rear speaker. Time lags of the first sound and the second sound is obtained from the outputs of the microphone, and the time difference between the time lags is obtained. An antiphase audio signal opposite to a reflected composite signal included in the first sound picked up by the microphone is provided by the sound field correcting circuit. The antiphase audio signal with the same amplitude is delayed based on the time difference and emitted from the rear speaker so as to cancel the reflected composite signal.Type: GrantFiled: August 5, 1999Date of Patent: November 5, 2002Assignee: Pioneer Electronic CorporationInventors: Minoru Yoshida, Fumio Matsushita, Satoshi Kumada, Yoshiki Ohta
