Abstract: Implementations are provided for increasing realism of robot simulation by injecting noise into various aspects of the robot simulation. In various implementations, a three-dimensional (3D) environment may be simulated and may include a simulated robot controlled by an external robot controller. Joint command(s) issued by the robot controller and/or simulated sensor data passed to the robot controller may be intercepted. Noise may be injected into the joint command(s) to generate noisy commands. Additionally or alternatively, noise may be injected into the simulated sensor data to generate noisy sensor data. Joint(s) of the simulated robot may be operated in the simulated 3D environment based on the one or more noisy commands. Additionally or alternatively, the noisy sensor data may be provided to the robot controller to cause the robot controller to generate joint commands to control the simulated robot in the simulated 3D environment.

Abstract: A heater and a vaporization device using the same are provided. The heater comprises an end for insertion into a cartridge, a body having a sidewall and at least one opening on the sidewall, and a chamber inside the body. The end has an outlet. The chamber and the opening provide an airflow path for an aerosol to be vented outside the heater through the outlet. The aerosol is generated from the vaporizable material when the body is heated.

Abstract: An electronic vaporization device with activation protection is provided. The electronic vaporization device includes a heater for heating a vaporizable material and a compartment housing the vaporizable material, said compartment being thermally connected to the heater. The electronic vaporization device further includes a power source providing electric power to the heater, said electric power being converted to thermal power. The electronic vaporization device further includes two or more contact points disposed on the outside surface of the electronic vaporization device. The electric power is provided when the two or more contact points are physically connected to an object having a resistance within a predetermined range.

Abstract: Utilization of past dynamics sample(s), that reflect past contact physics information, in training and/or utilizing a neural network model. The neural network model represents a learned value function (e.g., a Q-value function) and that, when trained, can be used in selecting a sequence of robotic actions to implement in robotic manipulation (e.g., pushing) of an object by a robot. In various implementations, a past dynamics sample for an episode of robotic manipulation can include at least two past images from the episode, as well as one or more past force sensor readings that temporally correspond to the past images from the episode.

Abstract: Disclosed are an electronic cigarette and a vaporizer thereof which are suitable for adjusting air inflow with a single hand. The electronic cigarette vaporizer includes a vaporizer base and a liquid reservoir connected to the vaporizer. An atomizing cavity is formed by an internal cavity obtained by the connection of the liquid reservoir and the vaporizer base. An air inlet passage communicated with the atomizing cavity is arranged at the liquid reservoir. An adjusting knob at the entrance of the air inlet passage for adjusting air inflow is also arranged at the liquid reservoir. An air inlet is arranged at the adjusting knob. By rotating the adjusting knob, the air inflow can be adjusted by relative position changes of the air inlet and the entrance of the air inlet passage.
