The timing of the reception window is based on a total timing misalignment between the UE (22) and the candidate node. In some embodiments, the duration of the reception window is based on an uncertainty in the timing misalignment estimate. Reception of user data is precluded during the uplink measurement signal reception window (on the allocated subband, if the full uplink carrier is not used). The UE transmits the uplink measurement signal in an uplink measurement signal transmission window. In some embodiments, the duration of the transmission window is sufficient to encompass the uplink measurement signal reception windows of all candidate nodes. |

Distributed techniques for detecting atypical or malicious wireless communications activity
Distributed techniques for detecting atypical or malicious wireless communications activity are disclosed. A server can iteratively generate sets of filters based at least in part upon observation data received from one or more Protects. The filters can be used by the Protect(s) to distinguish between sniffed wireless messages that are to be discarded and those that are to be reported to the server. The server can provide the generated sets of filters to the Protect(s) to cause the Protect(s) to process additional sniffed wireless messages utilizing the one or more sets of filters. Updated filters can cause fewer subsequent sniffed wireless messages to be reported than would have been reported by use of previous filters. Limited activity reporting by the Protect(s) enables a reduced communication load compared to full activity reporting without degrading the ability of the server to detect the atypical or malicious wireless communications activity. |

In order to get the best of both high and low common mode ranges, an adaptive body biasing method using a pair of replica devices is implemented. Each replica device corresponds to a NMOS (or PMOS) device that constitutes the input pair used in a logic circuit or other type of integrated circuits. This configuration helps to increase the threshold voltage of the device, utilizing body effect, at high input common mode voltage, as desired for NMOS, and at low input common mode voltage, as desired for PMOS. At the same time, this configuration scales the threshold back to normal at low input common mode voltages, thereby countering the negative impact of body effect. In short, the body bias applied to the NMOS (or PMOS) device helps in adapting the threshold voltage to the operating condition. |

Transmission path identification based on propagation channel diversity
Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques utilizing time diversity (e.g., different multipath arrivals at the same antenna) to achieve coherency from the same transmission node. For example, instead of initiating outgoing transmissions (e.g., power signals) at the same time, various embodiments can initiate the outgoing signals from the various antennas in a staggered timing that is a reversal of the arrival times of an incoming signal. As a result of staggering the start of the outgoing signals, the signals will arrive at the destination at approximately the same time even though they have traveled different paths having different propagation delays. |

Transformers with multi-turn primary windings for dynamic power flow control
Active impedance-injection module enabled for distributed power flow control of high-voltage (HV) transmission lines is disclosed. The module uses transformers with multi-turn primary windings, series-connected to high-voltage power lines, to dynamically control power flow on those power lines. The insertion of the transformer multi-turn primary is by cutting the line and splicing the two ends of the winding to the ends of the cut high-voltage transmission line. The secondary winding of the transformer is connected to a control circuit and a converter/inverter circuit that is able to generate inductive and capacitive impedance based on the status of the transmission line. The module operates by extracting power from the HV transmission line with the module floating at the HV transmission-line potential. High-voltage insulators are typically used to suspend the module from transmission towers, or intermediate support structures. It may also be directly suspended from the HV transmission line. |

Power management integrated circuit for driving inductive loads
A power management integrated circuit includes pairs of high-side and low-side drivers, sensing circuitry, and a processor. The high-side and low-side drivers are used in combination with external discrete NFETs to drive multiple windings of a motor. The N-channel LDMOS transistor of each high-side driver has an associated isolation structure and a tracking and clamping circuit. If the voltage on a terminal of the integrated circuit pulses negative during a switching of current flow to the motor, then the isolation structure and tracking and clamping circuit clamps the voltage on the isolation structure and blocks current flow from the substrate to the drain. An associated ESD protection circuit allows the voltage on the terminal to pulse negative. As a result, a large surge of current that would otherwise flow through the high-side driver is blocked, and is conducted outside the integrated circuit through a body diode of an external NFET. |
