  • Patent number: 10334961
    Abstract: A portable device for controlling an external electrical adjustable apparatus is provided. The portable device has a case, a signal transmitter connected to the electrical adjustable apparatus, a tilt sensor sensing a tilted angle and a controlling operation, a memory storing a threshold angle and a processor. The processor generates a controlling signal according to the controlling operation, and transmitting the controlling signal to an electrical adjustable apparatus for making the electrical adjustable apparatus raise/lower. The processor further determines that the electrical adjustable apparatus has collision when receiving a controlling signal used to control the electrical adjustable apparatus and the tilted angle is not less than the threshold angle, and sends a stopping signal to the electrical adjustable apparatus via the signal transmitter for making the electrical adjustable apparatus stop raising/lowering when determining that the electrical adjustable apparatus has collision.

  • Patent number: 5460794
    Abstract: A method of manufacturing a powdery AlN comprising steps of: a) providing an airtight vessel, b) preparing a powdery Al and a solid-state nitride, c) wrapping up the powdery Al and the solid-state nitride with an igniting agent, d) putting the wrapped Al and nitride into the vessel, e) evacuating the airtight vessel and filling therein with an N gas, and f) igniting the igniting agent. Since the powdery Al and solid-state nitride are completely wrapped up with an igniting agent, the reaction can be more rapidly and fully completed under a relatively low pressure. In addition, the present method can be used to obtain an AlN having a high purity.
