  • Patent number: 10921303
    Abstract: Apparatus, methods, and systems for transducing measurements from a medium of interest. One non-limiting example is in planta monitoring of plants. In one aspect, a micro- or nano-scale probe body includes one or more microprobes (e.g. microneedles or waveguides) to access desired plant tissue, and one or more microsensors on the probe body. A microcircuit on or in the probe body transduces relevant measurements from the microsensor(s). An output interface allows storage, communication, or transfer of the transduced measurement for further use. Non-limiting examples are processing into estimations of chemical concentrations or the like for biochemical sensing. As such, if used as in planta sensors, they can be minimally invasive and cost effective for both single use and use in sets for plural plants with one central station.

  • Patent number: 10838581
    Abstract: Electronic equipment is controlled with a touching-type signal input device. An inputted navigator-calling request that specifies a user request to navigate among a set of previously-opened application views of different applications is received. A request mode of the inputted navigator-calling request is compared with a predefined request mode associated with navigation among the set of previously-opened application views of the different applications. It is determined whether the request mode of the inputted navigator-calling request matches with the predefined request mode. An open-views navigator is displayed in response to determining there is a match. The open-views navigator has a set of open-views tabs distributed on at least part of a closed structure that each allow selective navigation to a previously-opened application view of one of the different applications.

  • Patent number: 10823630
    Abstract: We present a microelectromechanical system (MEMS) graphene-based pressure sensor realized by transferring a large area, few-layered graphene on a suspended silicon nitride thin membrane perforated by a periodic array of micro-through-holes. Each through-hole is covered by a circular drum-like graphene layer, namely a graphene “microdrum”. The uniqueness of the sensor design is the fact that introducing the through-hole arrays into the supporting nitride membrane allows generating an increased strain in the graphene membrane over the through-hole array by local deformations of the holes under an applied differential pressure. Further reasons contributing to the increased strain in the devised sensitive membrane include larger deflection of the membrane than that of its imperforated counterpart membrane, and direct bulging of the graphene microdrum under an applied pressure. Electromechanical measurements show a gauge factor of 4.4 for the graphene membrane and a sensitivity of 2.
