Systems and methods of friendly jamming for securing wireless communications at the physical layer are presented. Under the assumption of exact knowledge of the eavesdropping channel, a resource-efficient distributed approach is used to improve the secrecy sum-rate of a multi-link network with one or more eavesdroppers while satisfying an information-rate constraint for all links.

In addition, a block fading broadcast channel with a multi-antenna transmitter, sending two or more independent confidential data streams to two or more respective users in the presence of a passive eavesdropper is considered. Lastly, a per-link strategy is considered and an optimization problem is formulated, which aims at jointly optimizing the power allocation and placement of the friendly jamming devices for a given link under secrecy constraints.

An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output.

A second association unit defines, upon determination that the camera objects express the common object, the camera objects as a camera object group, and associates, if one of the camera objects constituting the camera object group is associated with a target radar object that is one of the radar objects, all the camera objects constituting the camera object group with the target radar object.

An invention regarding traffic management “Fast Lane On Warning” (FLOW) is disclosed whereby individual vehicles are informed and told what speed to go in order to pass through a traffic signal while the light is green. A converging, consolidating traffic managing “fast lane on warning” director sequencer works in conjunction with a traffic signal sequencer (commonly known in the art), both of which have the same service cycle period Pi. The (RGY) type phases and readout phases are set for each unique particular intersection. While the traffic sequencer controls repeating RGY cycles, the director sequencer instructs, generates, transmits repeating cycles of changeable readouts on one or more roadside unit (RSU) emplacements positioned up the road from the traffic signal for one or more lanes in one or more directions. These changing speed assignments or readouts, individually perceived by motorists, guide in motorists such that by the time they pass through the intersection, they will do so while the traffic signal is green, regardless of any random pattern of traffic individual motorists may have been in as they approached the emplacements.

In a general aspect, a location of detected motion in a space is determined. In some aspects, motion of an object in a space is detected based on wireless signals communicated through the space by a wireless communication system that includes multiple wireless communication devices. Each wireless signal is transmitted and received by a respective pair of the wireless communication devices. Motion indicator values are computed for the respective wireless communication devices. The motion indicator value for each individual wireless communication device represents a degree of motion detected by the individual wireless communication device based on a subset of the wireless signals transmitted or received by the individual wireless communication device. A location of the detected motion in the space is determined based on the motion indicator values.

An access control system cooperates with a security system. The access control system may be used to control aspects of the security system and the security system may be used to control aspects of a lockset used to lock or unlock an access point (e.g., door). A user can choose to arm or disarm the security system via the access control system and similarly the user may choose to lock or unlock the access point via the security system.

A system and method for detecting the activation of at least one alarm has at least one alarm detection device, at least one alarm, and a cloud storage platform. The alarm detection device can monitor and analyze the tonal and/or vibrational qualities of a sound to determine its origin. If the sound is determined to be a warning alarm (i.e. home security system), the information associated with that detection is forward to a gateway which then forwards an alert to an end user. The alarm detection system and methodology can be used with existing alarm systems (retrofit) with little added cost to the consumer. This creates a simple and affordable monitoring solution use in residential, commercial, and industrial settings.

A bingo-like game system and method utilizing bingo-like game cards depicting a grid formed of a plurality of spaces identifying outcomes associated with a live event such as a football game. A game system comprises a series of unique game cards with each game card depicting a grid formed of a plurality of spaces wherein the spaces identify outcomes associated with a live sporting event. Real time outcomes associated with the live sporting event dictate which matching spaces on the unique game cards are marked automatically or manually. Pre-established patterns of marked spaces determine winners of the game. The system further generates game cards having similar odds of winning based on the arrangement of possible outcomes associated with the live event.
