    摘要： A process of manufacturing a high electron mobility transistor (1; 1')/ comprising: providing an epitaxial substrate comprising a semi-insulating substrate (2), a buffer layer (3) and a barrier layer (4) sequentially stacked; forming a first and second current conducting electrodes (6, 7) formed on, and in ohmic contact with, the barrier layer (4); and forming a control gate (13) on, and in Schottky contact with, the barrier layer (4), between the first and second current conducting electrodes (6, 7). The control gate (13) is formed on the barrier layer (4) by initially forming a lower portion (11) of the control gate (13), then performing a thermal stabilization and annealing treatment to remove the damage to the crystal lattice of the surface of the semiconductor introduced by the preceding process steps and stabilize the metal-semiconductor interface of the Schottky junction, and finally forming an upper portion (12) of the control gate (13) on, and in electric contact with, the lower portion (11) of the control gate (13).

    摘要： An avionics switched full-duplex Ethernet communication Arinc 664p7 network (100) includes at least two independent elementary networks (N1, N2). Each elementary network includes one or more end systems (ESI) suitable to act as source end systems for data frames transmitted over the network, and one or more end systems (ES4) suitable to act as destination end systems for such data frames. Each elementary network further includes a switching function block (SW1, SW2) connected between the source (ESI) and destination (ES4) end systems. The Ethernet network is has one of the source (ESI), destination (ES4) end systems and the switching function block (SW1, SW2) includes timers (204) suitable to generate a common piece of timing information to be sent to the other devices of the elementary network in-order to enable the transmission of the data frames over the elementary network by one of the source end systems (ESI).

    摘要： A system comprising: • a SIP Proxy Server, and • one or more DMR Gateways to interface the SIP Proxy Server with one or more DMR Networks matching Private/professional Mobile Radio (PMR) features; wherein each DMR Gateway is univocally assigned with a SIP ID and is designed to: interpret messages from the SIP Proxy Server to manage DMR signalling/data/voice features toward DMR Terminals, and initiate DMR features on account of DMR Terminals operating under it and make requests for DMR signalling/data/voice features toward destinations belonging to another Network; wherein each DMR Gateway is further designed to: transcode an over-the-air, manufacturer-specific DMR Terminal registration into a SIP REGISTER message to result in the SIP Proxy server perceiving and managing the DMR Terminal as a SIP User Agent; and wherein the SIP Proxy Server is designed to: manage DMR signalling features, including voice call set-up, and DMR data features using the SIP MESSAGE method, and/or manage DMR signalling/data/voice group features.
