    摘要： A forced cooling circulation system for drilling mud, which includes a refrigeration unit (1), a secondary refrigerant tank (4), a coaxial convection heat exchanger (12) for mud and a mud pond (17), is disclosed. The refrigeration unit (1) is in connection with the secondary refrigerant tank (4) and the coaxial convection heat exchanger (12) for mud via a pump (2), and the coaxial convection heat exchanger (12) for mud is in connection with the mud pond (17) via a pump (15) and pipelines. Heat exchange tubes of the coaxial convection heat exchanger (12) for mud are disposed as a double-layer structure or a multi-layer structure, and the inner heat exchange tubes (23) are mounted inside of the outer heat exchange tubes (25). The secondary refrigerant or the mud is circulated in the annular space between the inner heat exchange tubes (23) and the outer heat exchange tubes (25), and the mud or the secondary refrigerant is circulated in the inner tubes (23). The flow of the circulated mud is opposite to that of the circulated secondary refrigerant, and insulation material (24) is painted on the external wall of the outer tubes (25).

    摘要： A device for suppressing ambient sounds from speech received by a microphone array is provided. One embodiment of the device comprises a microphone array, a processor, an analog-to-digital converter, and memory comprising instructions stored therein that are executable by the processor. The instructions stored in the memory are configured to receive a plurality of digital sound signals, each digital sound signal based on an analog sound signal originating at the microphone array, receive a multi-channel speaker signal, generate a monophonic approximation signal of the multi-channel speaker signal, apply a linear acoustic echo canceller to suppress a first ambient sound portion of each digital sound signal, generate a combined directionally-adaptive sound signal from a combination of each digital sound signal by a combination of time-invariant and adaptive beamforming techniques, and apply one or more nonlinear noise suppression techniques to suppress a second ambient sound portion of the combined directionally-adaptive sound signal.

    摘要： Methods for fabricating a photovoltaic device on complexly shaped fabricated objects, such as car bodies are disclosed. Preferably the photovoltaic device includes absorber layers comprising Copper, Indium, Gallium, Selenide (CIGS) or Copper, Zinc, Tin, Sulfide (CZTS). The method includes the following steps: a colloidal suspension of metal surface-charged nanoparticles is formed; electrophoretic deposition is used to deposit the nanopartieles in a metal thin film onto a complexly shaped surface of the substrate; the metal thin film is heated in the presence of a chalcogen source to convert the metal thin film into a metal chalcogenide thin film layer; a buffer layer is formed on the metal chalcogenide thin film layer using a chemical bath deposition; an intrinsic zinc oxide insulating layer is formed adjacent to a side of the buffer layer, opposite the metal chalcogenide thin film layer, by chemical vapor deposition; and finally, a transparent conducting oxide is formed adjacent to a side of the intrinsic zinc oxide, opposite the buffer layer, by chemical vapor deposition.

    摘要： An extension to the Universal Serial Bus (USB) protocol that utilizes reserved bits in the OHCI Endpoint Descriptors to signal which root hub port(s) should transmit the data. Typically, all ports transmit (broadcast) data. The present invention encodes transmission information that can be used by the hardware to effectively control which port(s) need to be tri-stated. However, by setting, the “on” bits for all the ports, the present invention retains standard USB functionality. Also provided is a method to increase the bandwidth of low speed devices connected to the USB bus by increasing the data payload for such devices.
