  • Patent number: 11245375
    Abstract: Systems are disclosed including a television (TV) set having included audio system. The TV set permits control over various functions, at least including audio volume, via a remote control. When the viewer activates the remote volume control, a graphic appears indicating the state of the volume control and, optionally the mute status. The graphic can be presented on the TV screen. In alternate embodiments, the graphic may be presented on a display of the remote, or even some other location, e.g., a different remote control. If a mute button is provided on the remote control, when the viewer activates the mute button, a graphic appears indicating the state of muting and, optionally, the volume control status. The TV set also offers control over various aspects of the audio system, including settings which go beyond volume up/down, generally through some sort of menu system.

  • Patent number: 10408859
    Abstract: A test fixture automatically placing an electronic device for testing includes a carrying module for holding the electronic device, a cover board module for supporting the carrying module, and a test module. The cover board module has an inductor for sensing the placement on the carrying module of the electronic device. The test module includes a driving member, a test plug connected to the driving member, a detector electronically connected to test plug, and an adapter movably positioned on the carrying module. The adapter includes a patch plug and a socket. When the inductor signals that the electronic device is on the carrying module, the test plug is driven into the socket of the adapter, and the patch plug of the adapter is further driven into the electronic device, to begin the testing procedure. A testing device having the test fixture is also provided.

  • Patent number: 9114378
    Abstract: A method of making iron and cobalt pre-catalysts and catalysts in activated, finished form suitable for use in Fischer-Tropsch synthesis. The pre-catalysts are prepared by mixing an iron or cobalt salt, a base, and a metal oxide textural promoter or support. The reaction is carried out in a solvent deficient environment. The resulting product is then calcined at temperatures of about 300-500° C. to produce a metal oxide. The catalysts are prepared by reducing the metal oxide in the presence of hydrogen at temperatures of about 300-500° C. and carbiding the reduced metal in the case of iron.

  • Patent number: 9079164
    Abstract: Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface.
