  • Publication number: 20240127627
    Abstract: Disclosed herein is an apparatus and method for detecting an emotional change through facial expression analysis. The apparatus for detecting an emotional change through facial expression analysis includes a memory having at least one program recorded thereon, and a processor configured to execute the program, wherein the program includes a camera image acquisition unit configured to acquire a moving image including at least one person, a preprocessing unit configured to extract a face image of a user from the moving image and preprocess the extracted face image, a facial expression analysis unit configured to extract a facial expression vector from the face image of the user and cumulatively store the facial expression vector, and an emotional change analysis unit configured to detect a temporal location of a sudden emotional change by analyzing an emotion signal extracted based on cumulatively stored facial expression vector values.

  • Patent number: 9511805
    Abstract: An endless track for providing traction to a vehicle, such as a construction vehicle, an agricultural vehicle or other work vehicle. The endless track has: an inner side for facing a plurality of wheels of the vehicle; a ground-engaging outer side for engaging the ground; a first lateral edge; and a second lateral edge. The endless track comprises an elastomeric body and a plurality of cores at least partially embedded in the elastomeric body. Each core extends transversally to a longitudinal direction of the endless track to provide transverse rigidity to the endless track. The endless track comprises an impact absorber in a lateral edge part of the endless track, the lateral edge part being located between the cores and a given one of the first lateral edge and the second lateral edge. The impact absorber facilitates an elastic deformation of the lateral edge part when the lateral edge part impacts an obstacle on the ground.

  • Patent number: 5825851
    Abstract: An automatic transferring apparatus for an exchange and a method therefor which automatically transfers an office line incoming call to an extension line includes: a unit connected to a switching circuit for converting received serial vocal data into parallel data; a memory for directly storing without further conversion the parallel-converted vocal data as a vocal guide message; a unit connected to the switching circuit for converting a DTMF signal into digital data; a unit for converting the parallel vocal data output from the memory into serial vocal data, and outputting it to the switching circuit; a unit for directly time slots assignment of the serial/parallel converting unit and parallel/serial converting unit; a unit connected to an exchange controller for receiving a command for automatic transfer; and an automatic transfer controller for controlling the memory in a recording mode to thereby store the parallel-converted vocal data as a vocal guide message, the controller outputting the vocal guide me
