Abstract: A foam maker has a bucket and a lid. The bucket has an outlet port provided in one of its walls, and a delivery tube connected to the outlet port. The lid includes a lid base and a lid top. The lid base has a frame and a compartment that receives a fan, a motor coupled to the fan, and a fluid inlet port through which foam solution and water can be introduced. The lid top has a water/foam inlet opening that is aligned with the fluid inlet port, and an air inlet port that is positioned adjacent the fan. An air tube is disposed inside the bucket, and has a first end connected to the lid base and communicating with the fan, and an opposite second end having an open distal end that is immersed inside foam solution. The air tube further includes an air chamber positioned adjacent the open distal end.

Abstract: A sea scooter has a main housing, a left arm pivotably attached to the left side of the main housing, a right arm pivotably attached to the right side of the main housing, a left barrel secured to the left arm, and a right barrel secured to the right arm. Each barrel has a fan and a motor for propelling the sea scooter through water. The left and right arms are locked by the first and second locking assemblies into a folded configuration against the left and right sides of the main housing when the sea scooter is not in use, and the left and right arms are pivoted away from the left and right sides of the main housing in a use configuration when the sea scooter is in use in the water. The motor is sand-proof and water-proof.

Abstract: Disclosed are a projection module, a structured light three-dimensional imaging device, and an electronic apparatus. The projection module includes a laser emitter and a reflective grating. The laser emitter includes a light emitting surface from which laser light is emitted. The reflective grating includes a reflecting surface arranged obliquely relative to the light emitting surface and opposite to the light emitting surface. The reflective face is provided with a grating microstructure thereon. The projection module can adjust a reflection angle of the laser light when expanding beams to generate a laser pattern.

Abstract: The localization of a vehicle is determined using less expensive and computationally robust equipment compared to conventional methods. Localization is determined by estimating the position of a vehicle relative to a map of the environment, and the process thereof includes using a map of the surrounding environment of the vehicle, a model of the motion of the frame of reference of the vehicle (e.g., ego-motion), sensor data from the surrounding environment, and a process to match sensory data to the map. Localization also includes a process to estimate the position based on the sensor data, the motion of the frame of reference of the vehicle, and/or the map. Such methods and systems enable the use of less expensive components while achieving useful results for a variety of applications, such as autonomous vehicles.
