A molecular switching device including: a channel unit which constructs an electron channel for allowing electron to flow therethrough; an electrode which is in contact with both ends of the channel unit; and a control unit which is connected with the channel unit through a connection unit to have an oxidation state or an electron density differentiated depending on voltage applied through the electrode, thereby varying an electric conductivity of the channel unit.

An organic memory device and a method of manufacturing the same are disclosed. The organic memory device includes an electron channel layer including an organic layer, in which nano particles of a uniform size are dispersed, interposed between metal electrodes, thus having electrical bistability. The organic memory device uses a change of electrical conductivity which results from a substantial change of the electrical structure of the electron channel layer when a voltage is applied. The organic memory device can be integrated using a simple manufacturing process, and ensures uniformity between devices due to the threshold voltage characteristics, even when highly miniaturized.

A method and system is provided for easily creating virtual graffiti that will be left for a particular device to view. During operation a device will be placed near a first point that is used to define a boundary for the virtual graffiti. The device will locate the first point, and use the point to define the boundary. The device will receive an image that is to be used as virtual graffiti, and will fit the image within or upon the boundary of the virtual graffiti. For example, the device may be consecutively placed near four points that will define a polygon to be used as the boundary for the virtual graffiti. An image will then be received, and the image will be fit within the polygon. Additionally, a device may create virtual graffiti from an image and a boundary.

Methods and systems for pulse generation assembly that includes a plurality of staged valves operably coupled serially in a bottomhole assembly of a wellbore tool. The plurality of staged valves are operated in a substantially synchronized manner, thereby generating a series of pressure pulses. The signal strength of the generated pulse signal is multiplied by the number of staged valves in the series, and the pulse generation assembly of the disclosure is less susceptible to jamming, shock, and erosion. Further, by sequentially stopping at least one stage of the assembly and then synchronously rotating other stages, amplitude modulation is accomplished.

A method and apparatus for messaging within a mobile virtual and augmented reality system is provided herein. During operation a user can create “virtual graffiti” (203) that will be left for a particular device (105, 107, 109) to view as part of an augmented reality scene. The virtual graffiti will be assigned to a particular physical location. The virtual graffiti is then uploaded to a network server, along with the location and individuals who are able to view the graffiti as part of an augmented reality scene. When a device that is allowed to view the graffiti is near the location, the graffiti will be downloaded to the device and displayed as part of an augmented reality scene. Content filtering may take place on the graffiti so that only specific graffiti is displayed on a user's device.

Systems and methods for monitoring and/or operating a rig site system are provided. In accordance with one embodiment, a method for monitoring a rig site system may include obtaining sensor data at a rig site and transmitting pre-processed sensor data pertaining to the sensor data from the rig site over a network link to a monitoring site. The method may also include demodulating the pre-processed sensor data at the monitoring site to produce demodulated data. The method may also include analyzing the demodulated data at the monitoring site. The sensor data may comprise at least one of surface sensor data, MWD sensor data, or LWD sensor data, or any combination thereof.
