Abstract: Systems and methods of dynamic IoT device regulation and control can aid in shifting a user's emotional state from a first state of mind to a preferred second state of mind, using the user's biomarker response to device settings. Particularly, an IoT device controller may be embedded within a wearable device that is wirelessly connected to a computing device and one or more IoT devices. Initially, each wearable device can be calibrated, wherein a matrix of sensed user biomarker responses can be generated. In some embodiments, the system continuously monitors user biomarkers to detect which physiological state exists. When the user enters into the first physiological/psychological state, the system can adjust each IoT device to align with the second state. When the system detects that the user biomarker response has not shifted, the system can continuously adjust IoT settings based upon a learning algorithm having monitored user biomarkers as input.

Abstract: Topological insulators, such as single-crystal Bi2Se3 nanowires, can be used as the conduction channel in high-performance transistors, a basic circuit building block. Such transistors exhibit current-voltage characteristics superior to semiconductor nanowire transistors, including sharp turn-on, nearly zero cutoff current, very large On/Off current ratio, and well-saturated output current. The metallic electron transport at the surface with good effective mobility can be effectively separated from the conduction of the bulk topological insulator and adjusted by field effect at a small gate voltage. Topological insulators, such as Bi2Se3, also have a magneto-electric effect that causes transistor threshold voltage shifts with external magnetic field. These properties are desirable for numerous microelectronic and nanoelectronic circuitry applications, among other applications.

Abstract: A method for enabling an interoperable vehicle safety network using wireless communication makes use of multiple traffic-monitoring devices that wirelessly communicate with each other. Each traffic-monitoring device records time-dependent inertial (TDI) data to determine a current trajectory. The TDI data includes current location, current velocity, and current orientation information. This information is used to monitor the current trajectory of each traffic-monitoring device and to predict the future position of each traffic-monitoring device. The trajectory of traffic-monitoring devices that are nearby to each other are analyzed to determine if there is a possibility of the devices colliding. If there is a possibility of the traffic-monitoring devices colliding, an alert is generated to prevent the collision. Additionally, the traffic-monitoring device sends out an emergency message if an accident actually occurs.

Abstract: This invention provides a new procedure for attaching molecules to semiconductor surfaces, in particular silicon. The molecules, which include, but are not limited to porphyrins and ferrocenes, have been previously shown to be attractive candidates for molecular-based information storage. The new attachment procedure is simple, can be completed in short times, requires minimal amounts of material, is compatible with diverse molecular functional groups, and in some instances affords unprecedented attachment motifs. These features greatly enhance the integration of the molecular materials into the processing steps that are needed to create hybrid molecular/semiconductor information storage devices.

An oxide layer covers the nanowire. A first conducting gate is disposed on top of the oxide layer adjacent with a non-zero separation to the anode. A second conducting gate is disposed on top of the oxide layer adjacent with a non-zero separation to the cathode and adjacent with a non-zero separation the first conducting gate. A controllable PN junction may be dynamically formed along the nanowire channel by applying opposite gate voltages. Radiation striking the nanowire through the substrate creates a current the anode and cathode.
