  • Publication number: 20200363506
    Abstract: A time-of-flight (ToF) transmitter with self-stabilized optical output phase with minimal overhead is described, where the transmitter may either function as a slave in that the laser pulse phase and width can be controlled by the master ToF receiver, or it can function as a master where the laser control pulse is generated on the same chip or a companion chip. When the ToF transmitter functions as a slave and receives the laser pulse control signal, the techniques of this disclosure can transform the receive path and the pre-driver circuit into part of a delay locked loop (DLL).

  • Publication number: 20200338485
    Abstract: The present invention discloses a method for preparing a simultaneous nitrogen and phosphorus removal lightweight material and the use thereof, and belongs to the technical field of environmental functional materials and sewage treatment. In the present invention, sulfur and an iron-based component are thoroughly melted and dispersed to obtain a molten mixture, where the iron-based component is a mixture of iron sulfides with carbonates of calcium and magnesium; and the above molten mixture is subjected to a foaming treatment to form the simultaneous nitrogen and phosphorus removal lightweight material. The simultaneous nitrogen and phosphorus removal lightweight material of the present invention has characteristics of high porosity, a large specific surface area, a light weight, and a high reaction activity.
