  • Publication number: 20240140819
    Abstract: The invention provides a process for preparing molybdenum and tungsten oxyhalide compounds which are useful in the deposition of molybdenum and tungsten containing films on various surfaces of microelectronic devices. In the process of the invention, a molybdenum or tungsten trioxide is heated in either a solid state medium or in a melt-phase reaction comprising a eutectic blend comprising alkaline and/or alkaline earth metal salts. The molybdenum or tungsten oxyhalides thus formed may be isolated as a vapor and crystallized to provide highly pure precursor compounds such as MoO2Cl2.

  • Publication number: 20230074053
    Abstract: A marine sonar display device comprises a display, a memory element, and a processing element. The processing element is configured to transmit a transmit electronic signal to a frequency steered sonar element that transmits an array of sonar beams into a body of water in a first direction towards the front of the marine vessel forming a first sonar wedge and a second array of sonar beams into a body of water in a second direction directly below the marine vessel forming a second sonar wedge, receive a receive electronic signal from the frequency steered sonar element, generate an array of sonar image slices, identify a gap in an underwater area between the first sonar wedge and the second sonar wedge, and control the display to visually present the array of sonar image slices in near real time and a sonar image slice in the gap.

  • Patent number: 11536820
    Abstract: A transducer system comprises a first frequency steered transducer array element and a second frequency steered transducer array element that is spaced apart from the first frequency steered transducer array element. The system additionally includes a processing element in communication with the first and second frequency steered transducer array elements. The processing element is configured to receive a first receive electronic signal from the first frequency steered sonar array element, receive a second receive electronic signal from the second frequency steered array sonar element, compare a difference in amplitude between the first receive electronic signal and the second receive electronic signal to determine a cross-track position of an underwater target, and control a display to present an indication of the cross-track position of the underwater target.

  • Patent number: 11351436
    Abstract: A golf launch monitor is configured to determine a flight characteristic of a golf ball. The golf launch monitor includes two low-speed cameras, a trigger device, and a processor. The trigger device is configured to detect a golf swing. The processor is configured to instruct, upon the trigger device detecting said golf swing, the first camera to capture the first ball image; instruct the second camera to capture the second ball image after a time interval, wherein the time interval is less than the first frame rate and the second frame rate; and determine, based at least in part on the first ball image and the second ball image, the flight characteristic of the golf ball.

  • Patent number: 6797967
    Abstract: A method is presented for compensating for the effects of charge neutralization in calculating the ‘true’ ion dose, i.e., the dose assuming no changes of charge state of ions during an implantation process. An ion beam is generated under normal operating conditions, e.g., stable vacuum exists, and no target is being implanted. At least one additional detector would be positioned in the target chamber, and a dose measurement conducted simultaneously with a measurement of the beam current with the Faraday, which is located outside of the charge neutralization region, to establish a reference ratio. A wafer is then placed at the target location, and simultaneous measurements made with the additional detector and Faraday, as before, to determine the ratio between the beam current and the detector during wafer implantation. Any drift from the reference ratio indicates the dose error due to charge neutralization from wafer outgassing during implantation.
