  • Publication number: 20200354623
    Abstract: Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

  • Patent number: 10833912
    Abstract: The present teaching relates to wireless Internet of Things. In one example, a time reversal client is disclosed. The time reversal client comprises a processor, a memory communicatively coupled with the processor, and a set of instructions, when executed by the processor based on the memory, that cause the time reversal client to perform the following steps: communicatively coupling with a time reversal server through a network, obtaining a set of channel state information (CSI), wherein the set of CSI is captured when at least one probing signal is sent from the wireless transmitter to the wireless receiver through a wireless multipath channel associated with a space, and causing the set of CSI to be sent to the time reversal server through the network.

  • Patent number: 7473918
    Abstract: A radiation-shielding container for storing a syringe includes a body assembly and a cap assembly securable to the body assembly such that first and second chamber portions define a chamber for storing the syringe. The body assembly includes a body shield formed of radiation shielding material, a body shell that defines a first cavity having an open end for receiving the body shield and defines a first chamber portion for receiving a portion of the syringe, wherein an inner wall of the body shell separates the first cavity and the first chamber portion, and a body plug secured to the body shell to cover the open end of the first cavity and retain the body shield within the first cavity.

  • Patent number: 5805202
    Abstract: A video surveillance system includes a remotely controllable video camera which generates a video signal, a video switch, a cable for transmitting the video signal from the video camera to the video switch, a control circuit connected to the cable for generating control signals to be transmitted to the video camera via the cable, and a control signal receiver associated with the camera and connected to the cable for receiving the control signals transmitted via the cable. The control signal receiver includes a detection circuit for automatically detecting the length of the cable and generating an adjustment signal indicative of the detected length of the cable. The control signal receiver also includes an adjustable circuit element which is adjusted on the basis of the adjustment signal so as to compensate for the detected length of the cable. The automatic cable compensation in the control signal receiver provides reliable detection of the camera control signals.

  • Patent number: 3963961
    Abstract: The phosphor screen of a cathode ray tube (CRT) has its phosphor coating protected against damage caused by a stationary or low sweep velocity electron beam that strikes its surface, by removal of the video signal that controls the beam whenever there is a simultaneous presence of video signal and absence of a proper horizontal or vertical sweep signal.

  • Patent number: 3961223
    Abstract: A cathode ray tube employing magnetic deflection coils for deflecting the electron beam in the horizontal and vertical directions, is corrected for the astigmatism error created by the non-uniform magnetic deflection field which causes a predictable elliptical distortion of the electron beam, through the use of two sets of correction coils mounted on a common annular magnetic core located on the neck of the CRT, which distorts the electron beam prior to its entry into the magnetic deflection field in a manner that is complementary to the distortion created by the non-uniform magnetic deflection field. The excitation currents for the correction coils are derived from the horizontal (Vx) and vertical (Vy) beam deflection voltage signals, in such a manner that the excitation current for the first correction coil is proportional to Vx.sup.2 - Vy.sup.2, and the excitation for the second correction coil is proportional to 2.sup.. Vx.sup.. Vy.
