  • Patent number: 11980568
    Abstract: A medical appliance for the treatment of one or more sleep disorders such as obstructive sleep apnea in a patient, the appliance comprising: a biasing member for inserting behind and exerting a force upon the patient's soft palate or tongue, wherein the biasing member is inserted in a reduced or minimized form and then expanded or firms once in place to exert the force. The appliance may be nasally inserted or be placed through the mouth. In a particular configuration, both the soft palate and tongue are biased to prevent obstruction of the flow of air in the nasopharyngeal airway.

  • Publication number: 20210375670
    Abstract: An apparatus comprises a structure including an upper insulating material overlying a lower insulating material, a conductive element underlying the lower insulating material, and a conductive material comprising a metal line and a contact. The conductive material extends from an upper surface of the upper insulating material to an upper surface of the conductive element. The structure also comprises a liner material adjacent the metal line. A width of an uppermost surface of the conductive material of the metal line external to the contact is relatively less than a width of an uppermost surface of the conductive material of the contact. Related methods, memory devices, and electronic systems are disclosed.

  • Patent number: 9415628
    Abstract: Application of carbon fiber reinforced polymer structures to metal vehicle wheels is effective in reducing the mass of the wheel while retaining suitable stiffness in the wheel structure. For maximum effect the reinforced polymer structure and the metal wheel must operate cooperatively. Because of the wide range of operating temperatures experienced by wheels and the large difference in coefficient of thermal expansion between metals and carbon fiber reinforced composites attachment of the polymer structure to the wheel by adhesive alone is problematical. However a wheel with an effective and durable reinforcement may be fabricated by confining, through mechanical interference, the reinforced polymer in a cavity in or on the spoke and by preheating the wheel before curing the polymer.

  • Patent number: 4117473
    Abstract: A horizontally oriented curve is produced on a raster type cathode ray tube display by storing curve data words in a memory and placing a series of dots on the cathode ray tube screen with each dot being at a height dictated by the value of the respective data word and at a horizontal position dependent on the order in which the respective data word is received. A dot counter provides an output signal for writing the curve data words into the address locations of the memory in the order in which the curve data words are received. A horizontal raster position counter provides a read address signal to the memory for each possible dot position in a horizontal scan. A comparator circuit compares each curve data word read out of the memory with a signal representative of the vertical position of the current horizontal scan and produces a video enable signal to produce a dot on the cathode ray tube screen when the compared signals are equal.
