Methods for implementing familiar electronic circuits at nanoscale sizes using molecular-junction-nanowire crossbars, and nanoscale electronic circuits produced by the methods. In one embodiment of the present invention, a 3-state inverter is implemented. In a second embodiment of the present invention, two 3-state inverter circuits are combined to produce a transparent latch. The 3-state inverter circuit and transparent-latch circuit can then be used as a basis for constructing additional circuitry, including master / slave flip-flops, a transparent latch with asynchronous preset, a transparent latch with asynchronous clear, and a master / slave flip-flop with asynchronous preset. 3-state inverters can thus be used to compose latches and flip-flops, and latches and flip-flops can be used, along with additional Boolean circuitry, to compose a wide variety of useful, state-maintaining circuits, all implementable within molecular-junction-nanowire crossbars by selectively configuring junctions within the molecular-junction-nanowire crossbars.

A wireless sensor network is installed inside pipelines using sensors and wireless transceivers that are small, low-cost, and rugged. The objective is monitoring the pipeline and recommending maintenance and repair at specific locations in the pipeline. Maintenance includes detection of internal corrosion using sensors that can result in leaks. Furthermore detection of leaks for prevention of catastrophic failures as a result of damage, such as third party mechanical damage. After establishing the wireless sensor network, the network is activated so the sensors can make measurements periodically or continuously using instructions transmitted via a base station. The sensor data from the various sensors are transmitted inside the pipe and extracted to access points in the pipeline to a remote computer that stores the data within the computer. The sensed information can be used for monitoring as well as analysis using a recommendation engine to provide maintenance and repair alerts.

Lighted reading glasses are provided to enable clear reading of normal sized text to occur when the reading material is held at usual distances from the reader in dimly lit or dark locations. The lighted glasses have high intensity lights, such as in the form of LEDs that generate narrow light beam cones and which are oriented via light mounts as by inward canting of the light beam cones to meet and overlap so high brightness light is generated in a conical overlap area of light which is maximized in size in the range of normal reading distances. The light mounts include housings that are very compactly sized via the use of small coin cell batteries for powering the LEDs they hold. The housings are tapered from their maximum width sized to be slightly larger than the diameter of the disc-shaped cell batteries to either end thereof along their length, and have a depth sized to accommodate two of the stacked very thin, e.g., one-eighth of an inch each, coin cell batteries. In this manner, a very small and compact light module is provided that, while especially well-suited for reading glasses due to the preferred inward cant provided by light mounting surfaces of the housing to tailor the location of the overlap lighted area to the reading area, can also be used with other types of head gear, such as caps or other types of hats.

A device to provide control of the trajectory of a lighter than air vehicle, such as a balloon, is provided. A lifting device, such as a wing on end, is suspended on a tether well below the balloon to take advantage of the natural variation in winds at different altitudes. The wing can generate a horizontal lift force that can be directed over a wide range of angles. This force is transmitted to the balloon by the tether. Due to this force, the balloon's path is altered depending on the relative sizes of the balloon and the wing. A relatively small amount of power is needed to control the system, possibly with a rudder. As the energy of the wind provides most of the force, the wind's energy does most of the work. The balloon is able to avoid hazards, to reach desired targets, to select convenient landing zones, and to provide other operational advantages. As a result, fewer flights must be terminated early due to an inability to control the trajectory, and it is easier to obtain permission to launch since a planned flight path can be achieved within a greater range of conditions.

A wiper seal is arranged in a fixed position within the seed disk assembly cavity and seals against the seed disk assembly as a support plate and seed disk of the seed disk assembly rotate over the wiper seal, so that the wiper seal creates a boundary between a vacuum zone and a non-vacuum zone inside of the seed disc assembly cavity.

The illustrative embodiment of the present invention is a unmanned aerial vehicle that includes a sensing system for the detection and limited identification of biological agents. The system is small, light weight, requires little power to operate and uses few consumables. The system incorporates elements that enable it to obtain an air sample, extract particulates from the air sample and retain them on a stationary-phase collection media, exposes the particulates to electromagnetic radiation, and monitor the particulates for fluorescent emissions. To the extent that fluorescent emissions are detected and exceed a predetermined value, an alarm is triggered. In some embodiments, in addition to performing real-time analyses on the extracted particulates, the collection media is removed from the system and the sample is subjected to more detailed analysis via additional equipment. Various sample-collecting regions on the collection media are “time stamped” or “location stamped” so that it can determined when and / or where each sample that is being analyzed “off-line” was obtained.
