Implementations of Data Bus Inversion (DBI) techniques within a memory system are disclosed. In one embodiment, a set of random access memory (RAM) integrated circuits (ICs) is separated from a logic system by a bus.

In such a system, data is DBI encoded and at least one DBI bit issued when writing to the modified RAM ICs. The RAM ICs in turn store the DBI bit(s) with the encoded data. When the encoded data is read from the modified RAM ICs, it is transmitted across the bus in its encoded state along with the DBI bit(s). The logic integrated circuit then decodes the data using the DBI bit(s) to return it to its original state. |

Systems and methods for calibrating presence and gesture detection thermal sensors in a mobile electronic communications device entail sensing an ambient temperature and designating the sensed ambient temperature as room temperature, and determining that a user appendage has touched, or is close to but not touching, the thermal sensor. If the user appendage has touched a lens of the thermal sensor, a sensed temperature just prior to that event is used as hand temperature. If the user appendage is close to but not touching the lens of the thermal sensor, the temperature during that event is used as hand temperature. A difference between the hand temperature and the room temperature is then determined and the presence and gesture detection functions for the device are calibrated based on the determined difference. |

Ground plane adjustment in a virtual reality environment
An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor. |

Black phosphorus gas sensor
The inventors experimentally demonstrated NO2 gas sensing performance of multilayer black phosphorous (BP) field effect transistors. The BP sensors were sensitive to NO2 concentration down to 5 ppb making them comparable in sensitivity to the best 2D material based sensors.

The systematic increase in conductance with increasing NO2 concentrations suggests NO2 molecules withdraw electrons and dope BP flakes with holes.

Assembly method for a shape memory alloy actuator arrangement
An SMA actuator arrangement is assembled using a strut element shaped to comprise a sacrificial strut body and crimp tabs held apart by the sacrificial strut body. A SMA wire is laid across the crimp tabs which are folded and pressed to form crimps holding the SMA wire. The crimps are then attached to static and moving parts, after which the sacrificial strut body is removed. The method allows the crimping to be performed without hindrance from the static and moving parts, the sacrificial strut body holding the relative locations of the crimps prior to attachment. |

Downdraft and updraft tornado wind chimney
A downdraft-tornado-wind-chimney and a updraft-tornado-wind-chimney create the compressed-and-high-velocity-air for a rotating-turbine. A photovoltaic-powered-blower and a high-temperature-solar-collectors create the compressed-and-high-velocity-air. A downdraft-tornado-wind-chimney inject the compressed-and-high-velocity-air into a photovoltaic-powered-blower, a high-temperature-solar-collectors and a rotating-turbine. A updraft-tornado-wind-chimney extract the compressed-and-high-velocity-air from a photovoltaic-powered-blower, a high-temperature-solar-collectors and a rotating-turbine. The combination of the updraft-tornado-wind-chimney, a downdraft-tornado-wind-chimney, a photovoltaic-powered-blower, and a high-temperature-solar-collectors drive a rotating-turbine. |

Mechanical system for extracting energy from marine waves
A mechanical structure used for extracting energy from oscillating marine waves is submitted. The apparatus comprises a plurality of buoyant tanks connected by a plurality of horizontal outriggers through a hinge assembly to a vertical frame located between the buoyant tanks. Marine waves create a pitching motion in the tanks forcing the outriggers to ascend and descend causing the vertical frame to rotate perpendicularly along the horizontal axis of the hinge. The power extraction system is comprised of a plurality of hydraulic cylinders connected to the vertical frame and outriggers. The pitching motion of the buoyant tanks and outriggers produce a vertical rotation along the horizontal axis of the hinge in the vertical frame, which forces contraction and expansion of the hydraulic cylinder assembly, thus extracting power from the relative motion between the members. |
