  • Publication number: 20230320810
    Abstract: A living body compressing clip 100 includes a clip body 1 with metallic arm parts 5a and 5b configured to hold a living body tissue. The clip body 1 includes compressing pieces 10 that protrude from distal end parts of the arm parts 5a and 5b in a long-side direction of the arm parts 5a and 5b. The compressing pieces 10 are formed from a flexible resin and hold a fluorescent dye. According to the living body compressing clip 100, the compressing pieces 10 causes a vascular network to collapse while holding the living body tissue by the arm parts 5a and 5b. Therefore, when the arm parts 5a and 5b hold the mucosal tissue of the tubular organ and excitation light is applied thereto, the fluorescence emitted by the compressing pieces 10 can be satisfactorily confirmed from the serosal side.

  • Publication number: 20230314158
    Abstract: A vehicle drive assist apparatus includes: a traveling environment information acquirer that acquires information on an area around a vehicle; an orientation detector that detects a face orientation or a line of sight of a driver; a projector that projects a course image indicating a vehicle's turning direction onto a road surface ahead of the vehicle; and a controller that sets the course image and controls the projector. The controller detects a driver's turn signal operation. Upon detecting the turn signal operation, the controller estimates a vehicle's turn position based on the face orientation or a direction of the line of sight. Upon determining, based on the information, that the turn position is not the intersection, the controller calculates a distance from the vehicle to the turn position based on the information, and set the course image indicating the turn position of the vehicle based on the distance.

  • Patent number: 11750771
    Abstract: An image acquisition unit acquires a video of a scene around a vehicle while the video is being captured. A recording control unit sets a moving image file for recording the video being captured, segmenting the video into predetermined units and records the video being captured in the moving image file until the predetermined unit is met. When an operation reception unit receives a request to play back a just-before portion while the video is being recorded, the recording control unit sets a subsequent moving image file that will be a new recording destination and closes a preceding moving image file that has been a recording destination, and a display control unit plays back the video, starting at a point of time reached by going back from an end of the preceding moving image file by a predetermined period of time.

  • Publication number: 20230227026
    Abstract: A driving assist device includes a driving assist controller. The driving assist controller is configured to perform driving assistance when the vehicle changes a course by crossing the oncoming lane. The driving assist controller sets a predicted travel region based on behavior of the oncoming vehicle when the oncoming vehicle is approaching the vehicle that enters an intersection. When the vehicle enters the predicted travel region in a travel path of the vehicle, the driving assist controller determines whether there is a possibility of contact between the vehicle and the oncoming vehicle based on the predicted travel region and the travel path of the vehicle. The driving assist controller causes the vehicle to stop outside of the predicted travel region when there is a possibility of the contact.

  • Publication number: 20230227029
    Abstract: A vehicle traveling control apparatus includes a sensor and a traveling control processor configured to function as an identification unit and a tentative identification calculation unit. The identification unit identifies whether the target detected by the sensor is a ghost or a real object based on results of the detection for first number of measurement cycles, and if the target is the real object and a possibility that the target and the vehicle come into contact with each other is present, causes a first traveling control to be executed. The tentative identification calculation unit determines whether the target is the ghost or the real object based on results of the detection for second number of measurement cycles, and when the target is the ghost and the possibility is present, causes a second traveling control to be executed. The second number is less than the first number.

  • Publication number: 20230227033
    Abstract: A driver assistance device acquires information about vehicle-driving environment ahead of the vehicle to detect an intersection. Upon determining that the vehicle makes a right- or left-hand turn at the intersection, the driver assistance device sets a projected course of the vehicle and recognizes a moving object ahead in a direction in which the vehicle making a right- or left-hand turn is headed. The driver assistance device calculates a movement vector from positional changes of the moving object to calculate a meeting point of a path of the object and the projected course. When an interval between times at which the vehicle and the moving object reach the meeting point is found to fall within a predetermined range, the driver assistance device determines that there is a possibility of interference between the vehicle and the moving object and then causes the vehicle to halt short of the meeting point.
