  • Patent number: 10477469
    Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2 V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.

  • Publication number: 20190212165
    Abstract: A method of identifying information during navigation is provided. Fork data is extracted from navigation data, the fork data corresponding to a road having a fork. A first node and at least two exit roads are extracted from the fork data, the at least two exit roads being roads in different directions. The fork data are identified as corresponding to a target fork in response to all of the at least two exit roads converging at the first node. A second node adjacent to the first node is queried in response to at least two exit roads not completely converging at the first node. The fork data are identified as corresponding to the target fork based on a distance between the first node and the second node meeting a preset condition.

  • Patent number: 9468155
    Abstract: A planting wall container structure includes a container main body and a planting panel. When the stem of a plant is inserted through any one of hole sealing portions of the planting panel to pass a through hole, a central aperture will be enlarged and clip pieces will be deformed to retain the stem of the plant. Plants can be inserted through the hole sealing portions to enter a soil accommodation room of the container main body. The soil accommodation room is filled with planting soil and poured with water for planting the plants on a front wall board. The water poured into the soil accommodation room is first stored in an upper water storage trough, and then the excess water flows to a lower storage trough guided by a liquid pass space to form multi-stage water storage before the water is drained through a drain hole.

    Abstract: A magnetic tunnel junction (MTJ) structure is provided over a device wherein the MTJ comprises a tunnel barrier layer between a free layer and a pinned layer; and a top and bottom electrode inside the MTJ structure. A hard mask layer is formed on the top electrode. The hard mask layer, top electrode, free layer, tunnel barrier layer, and pinned layer are patterned to define the magnetic tunnel junction (MTJ) structures. A first dielectric layer is deposited over the MTJ structures and planarized to expose the top electrode. Thereafter, the top electrode and free layer are patterned. A second dielectric layer is deposited over the MTJ structures and planarized to expose the top electrode. A third dielectric layer is deposited over the MTJ structures and a metal line contact is formed through the third dielectric layer to the top electrode to complete fabrication of the magnetic device.
