Abstract: The method for generating a secret key for encrypted wireless communications is a physical layer technique that exploits channel randomness between two nodes, the channel being characterized by reciprocity between the two nodes. Reference signals exchanged by the two nodes are used to faun a channel estimate, including gain location and phase location. The gain and phase locations are compared to threshold values, and locations exceeding the respective thresholds are stored in vectors. The moving differences between gain and phase locations at adjacent sampling times define secondary random processes. The moving difference values are quantized and converted to bit streams, which are concatenated to generate the secret key. Measures are provided to reduce parity errors, thereby reducing the bit mismatch rate (BMR).

Abstract: An apparatus and method that converts and transmits cell-network communications (mobile calls and messages) to Voice-over-Internet Protocol (VoIP) calls and messages, and vice versa, for those traveling outside their cell network. The system uses a server that authenticates the electronic device and offers other services; and a device software application. The invention converts and transmits cell-network (e.g., GSM) communications to Voice-over-Internet-Protocol (VoIP) calls and messages and vice versa—converting VOIP calls and messages to cell-network communications.

Abstract: The method and apparatus for angle of arrival estimation are used for estimating the angle of arrival of a received signal by a switched beam antenna array and a single receiver. The switched beam antenna array first collects an omnidirectional signal to be used as a reference signal. A main beam thereof is then switched to scan an angular region of interest. The collected signals from the switched beams are cross-correlated with the reference signal. The cross-correlation coefficient is the highest at the true angle of arrival and relatively negligible otherwise. The collected signal from each beam angle is cross-correlated with the omnidirectional reference signal to determine the angle of arrival of the received signal.

Abstract: An inverted Y-tool is positioned in multiphase wellbore fluid flowing through a wellbore. The inverted Y-tool separates at least a portion of gas from the multiphase wellbore fluid and, after separating at least the portion of the gas from the multiphase wellbore fluid, directs the multiphase wellbore fluid to a downhole pump that pumps the wellbore fluid in an uphole direction.

Abstract: Image-based analysis techniques are used for cognitive state vehicle navigation, including an autonomous or a semi-autonomous vehicle. Images including facial data of a vehicle occupant are obtained using an in-vehicle imaging device. The vehicle occupant can be an operator of or a passenger within the vehicle. A first computing device is used to analyze the images to determine occupant cognitive state data. The analysis can occur at various times along a vehicle travel route. The cognitive state data is mapped to location data along the vehicle travel route. Information about the vehicle travel route is updated based on the cognitive state data. The updated information is provided for vehicle control. The updated information is rendered on a second computing device. The updated information includes road ratings for segments of the vehicle travel route. The updated information includes an emotion metric for vehicle travel route segments.

Abstract: The present disclosure relates to a multi-effect desalination apparatus by partially dosing acids into only evaporators corresponding to a relatively high temperature part, while dosing a polymer-based anti-scalant into all the evaporators, to minimize a risk of a scale and corrosion with maximizing a top brine temperature of desalination facility, and a desalination method using the same.

Abstract: The presented system is a cost effective and energy saving mean of transmitting sunlight downward into a narrow alleys and streets, by using a day-lighting guiding acrylic panel that is capable of changing the direction and distribution of the incident light. The core of the proposed daylight guidance system is made up of light transmission panels that have sine wave shaped cross-section so that the panel functions as an optical diffusor perpendicular to the optical axis. The system consists of the panels and a lattice frame, which supports the panel. The proposed system is to be mounted on the building roof facing the sun but, since building sizes and orientations are different the frame is designed to be easily rotated to adopt different solar conditions such that substantially deep light penetration and high luminance level can be achieved.

Abstract: A method to operate an electronically controlled internal combustion engine that recognizes when thermal management mode of operation is being applied to an engine but is not attaining desired exhaust temperature for aftertreatment. When the Engine Control System (ECS) recognizes that the engine in operating in thermal management mode in a futile effort, the ECS aborts thermal management mode and returns to normal operating mode.

Abstract: A semiconductor charge transfer device (CTD) has an input network which includes an added gate region held at constant voltage, the added gate region being located between an input semiconductor charge injection region (input diode) and a signal gate region. In this way the amount of signal charge transferred into the CTD is less sensitive to unavoidable noise in the clock voltages which are applied to electrodes associated with the bulk of the CTD for the purpose of shifting the signal charge therethrough; and the linearity of the ratio of injected charge to signal voltage is also improved.
