Systems, methods and apparatus are described for a HERF weapon that may emit high-energy radio waves at a target based on locational information and a frequency associated with the target. The HERF weapon may receive the frequency and locational information from a sensing system. The HERF weapon may emit a high energy pulse toward the target and on the frequency associated with the target to disable or destroy the target without affecting nearby devices. The HERF weapon may allow the user to avoid detection by using a frequency that corresponds to the target's operating frequency.

Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to reduction and/or identification of one or more health risks in a facility. For example, by sensing a bodily characteristic of an individual in a facility, e.g., by sensing at least one environmental characteristic. For example, by sensing surface cleanliness. For example, by tracking personnel in the facility. For example, by suggesting routes in an enclosure based at least in part in personnel concentration in the facility. Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to monitoring occupancy of a facility.

A system for providing integrated detection and deterrence against an unmanned vehicle including but not limited to aerial technology unmanned systems using a detection element, a tracking element, an identification element and an interdiction or deterrent element. Elements contain sensors that observe real time quantifiable data regarding the object of interest to create an assessment of risk or threat to a protected area of interest. This assessment may be based e.g., on data mining of internal and external data sources. The deterrent element selects from a variable menu of possible deterrent actions. Though designed for autonomous action, a Human in the Loop may override the automated system solutions.

Systems and methods are described for a cyber-physical vehicle management system generated by an Integrated Secure Device Manager (ISDM) Authority configured to manage licensing and approval of Cyber-Physical Vehicle (CPV)s, a public/private key pair and a unique ID for the Authority, create a self-signed Authority token signed by the private key, send the Authority token to a plurality of ISDM Node device configured to verify Module device authenticity and in communication with the Authority, store, by each Node, the Authority token, and mark, by each Node, the Authority token as trusted.

An apparatus, system, and method for determining the presence of a mobile device located in a predetermined detection zone within a vehicle are disclosed. A detection module receives a communication signal, determines that the communication signal was transmitted by a mobile device located within a predetermined detection zone within a vehicle, and a control module transmits a control signal to the mobile device located within the predetermined detection zone. The system further includes a monitoring logic to monitor a functional system of the vehicle activating the transmission of the control signal by the control module when the monitored functional system is activated and the detection module determines that the communication signal was transmitted by the mobile device located within the predetermined detection zone.

A portable Electromagnetic Countermeasure (ECM) device is disclosed for military and civilian population protection from electromagnetic communications and attack, including cell phones, radios, radio-triggered explosive devices, and other personal and portable devices comprising transmitters and receivers. The portable ECM device is usable by a person such as a soldier or policeman to protect themselves and other people around them from spy, guerrilla, military and terrorist threats. The portable (ECM) device comprises a first antenna and a second antenna, both to communicate radio signals with a software defined radio (SDR), and a control pack having a microprocessor operable by remote network connection, or by a mode selector on board the device, to control the SDR according to a mode selected, to receive, produce, and classify radio signals.

Disclosed is a radio frequency communication and jamming device configured for physically secured friendly radio frequency communication and for jamming hostile radio frequency communication, the radio frequency communication and jamming device including: an antenna arrangement having a transmission section for transmitting outgoing signals and a receiving section for receiving incoming signals; a receiver device configured for extracting an incoming information signal from the incoming signals received via the receiving section of the antenna arrangement in a receiving frequency band; a jamming generator configured for generating at least one jamming signal for jamming at least one jamming frequency band, wherein the jamming signal is transmitted as one of the outgoing signals via the transmission section, wherein the at least one jamming frequency band includes the receiving frequency band; and a self-interference cancellation device configured for cancelling portions of the at least one jamming signal in the incoming signals received via the receiving section at least in the receiving frequency band.

A system for disrupting Radio Frequency communication of a plurality of unmanned aircraft. The system comprises: a directional antenna; a transmitter; a drive system connected to the directional antenna and configured to move the directional antenna; and a control system. The control system causes the transmitter to generate a signal waveform configured to disrupt Radio Frequency communication of an unmanned aircraft for emission by the directional antenna, and causes the drive system to move the directional antenna such that each of the plurality of unmanned aircraft is irradiated intermittently by the emitted radiation. Each of the plurality of unmanned aircraft is irradiated for a first period of time and not irradiated for a second period of time, the second period of time is less than or equal to 5 seconds.

A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows). In some cases, the computational resources of the window control system are utilized by other building systems and devices.
