Abstract: A virtual reality head-mounted display is disclosed which comprises an inflatable lining module disposed within a frame of a monitor main body coupled with a positioning band. The inflatable lining module is composed of a foam body, an inflatable cushion, an air passage, an air pump, an air pressure sensor, a contact sensor and a control module. When the contact sensor detects an external pressure, it sends an enabling signal to the control module to drive the air pump to operate, and an air is introduced to the inflatable cushion through the air passage to inflate the inflatable cushion, so that the form of the foam body is correspondingly adjusted. When the air pressure sensor detects the pressure inside the inflatable cushion higher than a specified threshold interval, it sends a disabling signal to the control module, and the air pump is accordingly controlled to stop operating.

Abstract: A gas transportation device includes a gas outlet cover, plural flow-guiding pedestals and plural gas pumps. The gas outlet cover includes a gas outlet nozzle and a gas outlet cavity. The gas outlet nozzle and the gas outlet cavity are in communication with each other. Each flow-guiding pedestal includes a main plate, a protruding frame and a chamber frame. The main plate includes a recess and a communicating aperture in communication with the recess. The gas pumps are disposed inside the chamber frames of the flow-guiding pedestals, respectively. The gas outlet cover covers the flow-guiding pedestals and is connected to the protruding frames, whereby plural convergence chambers are defined and are in communication with the gas outlet cavity. Consequently, the gas is transported through the recesses, the communicating apertures, the convergence chambers and the gas outlet cavity sequentially, and finally is discharged out from the gas outlet nozzle.

Abstract: An actuating and sensing apparatus includes a circuit board, a housing, an actuating device and a sensor. The housing is disposed on the circuit board and includes an entrance opening, an exit opening and a compartment. The compartment is in communication with an external environment of the housing through the entrance opening and the exit opening. The actuating device is disposed within the compartment and closing the exit opening. The sensor is disposed within the compartment and corresponding to the entrance opening. When the actuating device is enabled, a gas within the compartment is guided to the external environment outside the housing, and a pressure gradient is generated in the compartment so as to introduce a gas from the external environment outside the housing into the compartment through the entrance opening to make the gas detected by the sensor.

Abstract: An air-cooling heat dissipation device includes a guiding carrier and a gas pump. The guiding carrier includes a pump-receiving recess, a first guiding chamber, a second guiding chamber, a communication structure and at least one discharge groove. The first guiding chamber is concavely formed in the pump-receiving recess, and is in communication with the first guiding chamber. The communication structure is communicating between the first guiding chamber and the second guiding chamber, while the electronic component is disposed within the second guiding chamber. The gas pump is disposed within the pump-receiving recess. When the gas pump is enabled, an ambient gas is driven to sequentially flow through the first guiding chamber, the communication structure and the second guiding chamber to remove the heat from the electronic component. Since the discharge groove is communicating between the second guiding chamber and exterior surroundings, the heated gas is outputted from the discharge groove.
