Post patch assembly for mounting devices in a tire interior

A modular electronic assembly for integration with a pneumatic tire includes a mounting patch, a power source, and at least one electronic device supported by a substrate. The mounting patch is preferably adapted for positioning on the inner liner of a pneumatic tire, and the power source is at least partially embedded in the mounting patch. Such embedded positioning of the battery results in an overall structure with a lower center of gravity than previous tire electronics assemblies, thus having increased mechanical stability and survivability in a tire environment. Electronic device(s) supported on the substrate may receive power from the power source, which in some embodiments corresponds to one or more batteries. The substrate supporting the at least one electronic device may be attached to the mounting patch by a variety of fashions. Exemplary attachment configurations may correspond to an adhesive layer, a hook and loop tape combination, or physical interconnection via terminals extending from the power source through the support substrate. Exemplary electronic devices may include such components as condition-responsive devices including transducers, acoustic devices, sensors, etc. for sensing certain environmental conditions such as temperature and/or pressure, tire revolution counters, vehicle speed sensors, sidewall deflection sensors, tire displacement sensors, microprocessors, memory modules, RFID transponders, light assemblies, data transmitters and/or receivers, and power, supply components. Selected of the electronic devices (including one or more antennas associated with any RF devices) may be encapsulated by a non-conductive rubber or elastic material to facilitate effective transmission characteristics. Conductive springs, flexible conductive elastomer or fatigue-resistance metal may be used to interconnect various electronic components (such as an RF device to an antenna).

Large-scale preparation method of transparent super-hydrophobic/super-amphiphobic coating

The invention discloses a large-scale preparation method of a transparent super-hydrophobic / super-amphiphobic coating. The method comprises the steps of ultrasonically dispersing nano particles into an alcohol-water mixed system and carrying out hydrolysis and condensation reaction on the nano particles and fluoride-free or fluorine-containing organosilane under the acid or alkali catalysis action to prepare a transparent suspension liquid of a fluoride-free or fluorine-containing organosilane polymer-nano particle compound; and applying the transparent suspension liquid of the compound on the surface of a substrate material through spraying or dip-coating to obtain the transparent super-hydrophobic / super-amphiphobic coating with good performance. Preparation of the transparent super-hydrophobic / super-amphiphobic coating of 10-100m<2> can be completed within an hour; large-scale preparation of the large-area transparent super-hydrophobic / super-amphiphobic coating is achieved for the first time; the preparation method is low in cost and simple in process; and the prepared coating has excellent super-hydrophobic or super-amphiphobic property, relatively good mechanical stability, chemical stability and environment stability, and has a wide application prospect.

Adjustable tripod mechanism to support devices or transducers for scientific measurement

The present invention relates to an adjustable tripod mechanism to support devices/transducers for scientific measurements such as weather station, radio transceiver, acoustic modem, and the like. More particularly, this invention relates to a novel, fully mechanical, and hand-operated tripod stand that incorporates (1) capability for rigidly mounting devices such as instruments, transducers, and so forth on a desired plane at a desired height for measurement of a multiplicity of parameters (e.g., meteorological parameters such as wind speed and direction, solar radiation, air temperature, barometric pressure, humidity, and the like); (2) rotation of any attached/mounted-device/transducer in the azimuthal direction at any angular intervals to facilitate orienting a mounted device in a given direction without the need for rotation of the legs of the tripod; (3) capability for partitioning of the tripod into a multiplicity of desirable smaller segments, thereby enabling its trouble-free transportation to remote areas; (4) trouble-free coupling of a plurality of separate members to achieve the desired height for the tripod stand to suit a given installation environment; (5) improvement in the efficiency of assembly, de-assembly, and packing of the tripod system by rendering its members compact and dismountable; (6) achieving elegance in appearance and ease in mounting; (7) improvement in mechanical stability as a result of an adjustably wider base area; and (8) facility for locking the tripod mechanism to the floor to prevent its translational/angular movement under drag force induced by the prevailing wind.
