  • Patent number: 9860680
    Abstract: A Bluetooth controller associated with a host device can be configured to automatically configure and setup a Bluetooth LE HID without the use of hidden menus or other setup options involving multiple steps (or other input devices). The Bluetooth controller executes background scan operations to detect at least one Bluetooth LE HID to connect to the host device. Each Bluetooth packet received at the Bluetooth controller is analyzed to determine whether the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID. In response to determining that the received Bluetooth packet is a predefined Bluetooth LE HID packet type transmitted by the Bluetooth LE HID, the received Bluetooth packet is provided to a Bluetooth LE HID module of the Bluetooth controller. Otherwise, the received Bluetooth packet is provided to a Bluetooth HCI module of the Bluetooth controller.

  • Patent number: 8173211
    Abstract: A method of production of carbon nanoparticles comprises the steps of: providing on substrate particles a transition metal compound which is decomposable to yield the transition metal under conditions permitting carbon nanoparticle formation, contacting a gaseous carbon source with the substrate particles, before, during or after said contacting step, decomposing the transition metal compound to yield the transition metal on the substrate particles, forming carbon nanoparticles by decomposition of the carbon source catalysed by the transition metal, and collecting the carbon nanoparticles formed.

  • Publication number: 20070218283
    Abstract: A method of producing carbon-encapsulated metal nanoparticles, for example carbon-encapsulated magnetic metal nanoparticles, including providing a carbon-containing metal salt or organometallic compound in a reactor, for example a vessel having a restricted opening and decomposing the carbon-containing metal salt or organometallic compound, for example by heating, whilst maintaining carbon within the reactor to form carbon-encapsulated metal nanoparticles.

  • Publication number: 20050063891
    Abstract: A method of producing carbon nanoparticles comprises the steps of: passing a gaseous carbon source through a heated reactor; and adding catalyst supported on substrate particles or thermally decomposable catalyst precursor supported on substrate particles to the heated reactor to form a fluidised bed; such that carbon nanoparticles are formed in the heated reactor.
