摘要:
The invention provides a distance measuring apparatus for measuring distance to a target, having: a light emitter for emitting a measuring light; a light receiving system for receiving a reflected light reflected from the target and outputting a sensing signal; a comparator having a reference signal input terminal for receiving a reference signal, a sensing signal input terminal for receiving the sensing signal, and a comparison result signal output terminal for outputting a comparison result signal according to comparison results between the reference signal and the sensing signal; and a process and control module for providing the reference signal to the reference signal input terminal of the comparator and adjusting the reference signal according to the comparison signal.
摘要:
A programmable memory device includes a plurality of one-time programmable (OTP) memory units, a search unit, a writing unit, and a reading unit. Each OTP memory unit is assigned an address. The search unit searches for the first writable OTP memory unit from the plurality of OTP memory units in a writing operation, or searches for the last programmed OTP memory unit from the plurality of OTP memory units in a reading operation. The writing unit writes data to be written and the bit length of the data to the first writable OTP memory unit. The reading unit sequentially reads data from the last programmed OTP memory unit.

摘要:
A method of using nanoparticles to fabricate an emitting layer of an optical communication light source on a substrate is proposed, in which a host capable of reacting with unstable ions on the surface of a rare earth ions nanomaterial is used as a carrier of nanoparticles to make the rare earth ions nanomaterial release rare earth ions, thereby forming an emitting layer that can be excited by an external current or light source to emit light.
