  • Publication number: 20240241367
    Abstract: An optical scanning device includes a light source and a MEMS optical deflector mounted on the same substrate, at least one optical path generation mirror configured to generate an optical path which causes a light beam emitted from the light source to enter the MEMS optical deflector, and a lens arranged between the light source and the first optical path generation mirror. A shielding plate has an elliptical aperture and is attached to the optical path generation mirror. The light beam from the lens has a peripheral edge on a cross section thereof, which is cut by the elliptical aperture.

  • Patent number: 12032098
    Abstract: An accuracy of detection of a road surface or the like is improved even in a state where a peak power of reflected light is low. A sensor control device is configured to be mounted in a vehicle capable of acquiring a current location and configured to control a LiDAR-having a light source which emits light to a predetermined region and a light receiving element which receives reflected light of the emitted light, and the sensor control device includes an adjustment unit which acquires map information and adjusts a light receiving level of a light receiving signal of the light receiving element. The adjustment unit determines, based on the map information, a region for which the light receiving level with respect to the light receiving signal is to be adjusted.

  • Publication number: 20230222728
    Abstract: The length of a moving body made of a material that hardly reflects laser light is measured with high accuracy. First point cloud information based on three-dimensional point cloud information of a first region A1 of a moving body path RW in which a movement direction is set, second point cloud information based on three-dimensional point cloud information of a second region A2, and third point cloud information based on three-dimensional point cloud information of a third region A3 downstream of the second region A2 are acquired in a time series. A velocity VAM of a moving body AM is calculated based on a temporal change of the first point cloud information A1. A front end position FE of the moving body AM at a first time T1 is calculated based on the second point cloud information A2. A rear end position RE of the moving body AM at a second time T2 is calculated based on the third point cloud information A3.

  • Patent number: 11644324
    Abstract: The present invention identifies a danger spot effectively. In a navigation device 10, a danger spot identification unit 34 identifies a jump-out danger spot on the basis of past information which is acquired by a past information acquisition unit 24 and indicates a situation of a jump-out accident in the past, and surrounding information which is acquired by a surrounding information acquisition unit 32 and indicates a surrounding situation of a vehicle. Here, the past information includes surrounding facility identification information (information related to an identification planimetric feature) used for identifying a jump-out danger spot and information related to a jump-out object. As a result, the danger spot identification unit 34 can identify a danger spot of a jump-out which can occur due to a planimetric feature (a facility) in a jump-out accident. Therefore, the navigation device 10 can identify a jump-out danger spot effectively.

  • Publication number: 20180070175
    Abstract: When musical piece is reproduced and outputted, an attribute information acquisition unit acquires attribute information for the musical piece. An attribute information acquisition unit transmits, to a management device, the attribute information as attribute specification information. In the management device, when the attribute specification information has been received, a derivation unit acquires, from adjustment information in a storage unit, octave band information for setting, musical instrument frequency of appearance for setting, and L/R phase difference information for setting that correspond to the attribute specification information. On this basis, the derivation unit generates sound quality adjustment setting value updating information, speaker setting updating information, and signal processing setting updating information, and transmits, to a sound device, these pieces of information as setting updating information.

  • Publication number: 20170245070
    Abstract: A derivation unit (240) determines, as a specified rhythm component of a musical piece, a rhythm component detected within a predetermined time range including a time of reception of tap timing information TAP and derives a first frequency band the spectrum intensity of which is equal to or greater than a predetermined value. The derivation unit (240) also determines, as an unspecified rhythm component, a rhythm component detected outside the predetermined time range including the time of reception of the tap timing information TAP and derives a second frequency band the spectrum intensity of which is equal to or greater than the predetermined value. Thereafter, a calculation unit (250) calculates a third frequency band, which is included in the first frequency band and which does not include the second frequency band, and then transmits, to a filter unit (260), a passed-frequency designation BPC that designates the third frequency band.

  • Patent number: 8060144
    Abstract: In a wireless communication system (10), when a direct link mode is to be canceled, a station (200) generates a confirmation packet for confirming an unused band of the wireless communication system (10) and transmits the confirmation packet to an access point (100). At the access point (100), a band management part (130) determines the unused band, and a packet generating part (112) generates a response packet indicative of the unused band, which is then transmitted to the station (200). The station (200) determines, based on the unused band indicated by the response packet, whether the direct link mode should be canceled, and transmits a cancellation request packet to the access point (100) if the unused band is sufficient. At the access point (100), the direct link mode is switched to a normal mode for cancellation in response to the cancellation request packet.

  • Publication number: 20110116640
    Abstract: The contents reproducing system includes a plurality of contents reproducing units, and the delay amount calculating unit calculates the delay amount with which each of the contents reproducing units reproduces the contents data. The delay amount is the time to delay the reproduction of the contents data, for example. The contents reproducing unit reproduces the contents data, by each of the contents reproducing units, with the delay based on the delay amount calculated by the delay amount calculating unit. By automatically controlling the delay amount of the contents data in this manner, the contents reproducing system can create a sound space with wrapped feeling and spreading feeling.
