Abstract: A therapeutic pillow is disclosed. The therapeutic pillow provides support to a user's head, neck, back, and spine when lying down on the pillow. The pillow includes a head support, an elongated spine support, a firm support member for supporting the elongated spine support, and a lower member for manipulating the pillow. When lying down on the pillow the force exerted onto the elongated spine support compresses the elongated spine support. This compression causes an end of the elongated spine support that is connected to the head support to bend, which in turn causes the head support to bend at an angle towards the vertical axis of the pillow. Further, when lying on the pillow the lower member protrudes through a user's legs, which enables users to grasp the lower member with their legs and perform therapeutic exercises with the pillow.

Abstract: The present disclosure relates to a detecting system fusing lidar point cloud and image, which includes a laser emitting means (101), a beamsplitter (102), a beam deflecting means (103), a first laser detecting means (104), a coaxial optical receiving means (105), a second laser detecting means (106) and an image detecting means (107). By using the coaxial optical receiving means, a third return light received by the second laser detecting means and a fourth return light received by the image detecting means are both from a first return light which includes a reflected light generated by the second laser beam irradiating a target object and a reflected light generated by a background illuminating light source irradiating the target object. The system may acquire lidar point cloud information and image information synchronously, which facilitates the subsequent fusion of the lidar point cloud information and the image information and reduces the complexity of calculation.

Abstract: A thrust vectoring exhaust nozzle is disclosed. The nozzle includes an inner nozzle for changing a first degree-of-freedom of exhaust gas, an outer nozzle for changing a second degree-of-freedom of exhaust gas, a mounting bracket, a first linear actuator, a second linear actuator, a first double universal joint, and a second double universal joint. The inner nozzle is coupled to the outer nozzle. The inner nozzle is coupled to the mounting bracket. The outer nozzle is coupled to the first and second joint. When the nozzle is mounted, the inner nozzle, the outer nozzle, and the exhaust are coaxially aligned in neutral position. Actuation of the first and second linear actuators drives the first and second double universal joints independently to each other. The independent motion of the first and second double universal joints rotates the inner and outer nozzles simultaneously about the exhaust in a horizontal direction and vertical direction enabling thrust vectoring.
