The present invention is directed at an electromagnetic weapon event detection device configured to continuously monitor properties of ambient electromagnetic fields harmful to humans. Monitored properties may include real-time electromagnetic field strength, peak electromagnetic field strength in a time period, electromagnetic field exceedance, and cumulative electromagnetic field dose. The device detects powerful microwave and millimeter wave electromagnetic emissions. The device may be integrated into a variety of products, including, but not limited to, a keychain attachment, lanyard attachment, eyeglasses frame, handheld instrument, identification card, writing instrument, or USB dongle. The device may be powered by internal dc power sources, external dc power sources, or energy harvesting.

Device for the detection of harmful electromagnetic fields

An apparatus detects complex time-variant electromagnetic disturbances resulting from a high-altitude nuclear electromagnetic pulse (EMP) or solar storm. The device relies on a circuit () to monitor the input power lines () for sustained conducted electrical disturbances associated with the Ephase of an EMP or solar storm. A separate circuit () monitors the power lines and the ambient environment () for transient electromagnetic pulse disturbances associated with the Eand Ephases of an EMP. A housing () has a pair of AC mains wall plug prongs () extending from a side. When sustained electrical disturbances or transient electromagnetic pulse disturbances are detected, the apparatus provides a visual alarm (), audible alarm (), and discrete indication signal () that can be used to disconnect () or redirect the flow of electrical power.

Apparatus for detection of electrical disturbances resulting from electromagnetic pulse and solar storm

The present invention is directed at an electromagnetic field monitoring device configured to continuously monitor properties of an electromagnetic field. The device may be solely powered by the ambient electromagnetic energy of an electromagnetic field, removing any reliance on external power sources or batteries. Monitored properties may include real-time electromagnetic field strength, peak electromagnetic field strength in a time period, electromagnetic field exceedance, and cumulative electromagnetic field dose. The device detects otherwise concealed sources of electromagnetic fields, such as hidden cameras or microphones. The device may be integrated into a variety of products, including, but not limited to, a keychain attachment, lanyard attachment, eyeglasses frame, handheld instrument, identification card, writing instrument, business card, adhesive sticker, ring, or necklace pendant.

Electromagnetic field monitoring device

An apparatus detects an E3 phase and E1 and E2 phases of an electromagnetic pulse (EMP). A pulse detector detects E1 and E2. A sustained level detector connects to a mains utility power supply line to detect E3. A delay timer holds an indication of a detected E1 or E2 for a predetermined time limit of about 10 minutes. A latch holds an indication that an EMP has occurred when an E3 occurs following an E1 or E2 within the predetermined time limit. An alarm indicates an EMP. A mechanical actuator disconnects the mains utility power supply line from utility power when an EMP is so indicated. The mechanical actuator can be mounted to a panel front face of a circuit breaker box in a configuration to push open a switch surface of a circuit breaker switch lever.

A multi-stage surge protection device protects against complex, time-variant voltage transients, including those resulting from a high-altitude nuclear electromagnetic pulse or a solar coronal mass ejection. The transient voltage suppressor limits the let-through voltage to a clamping level and provides indication to the crowbar circuit when it is no longer able to do so. Once the clamping level is no longer able to be maintained, the crowbar circuit draws enough current to trip an upstream protective device, such as a breaker or fuse. A low-pass filter can be added to significantly lower the let-through voltage of the device for short-duration pulses, and help to spread the energy to more effectively utilize the transient voltage suppressor.

Surge protection device for complex transients

A three-stage surge protection device protects against complex, time-variant voltage transients, including those resulting from a high-altitude nuclear electromagnetic pulse or a solar coronal mass ejection. The device relies on interaction between a snubbing low-pass filter, a transient voltage suppressor, and an electronic crowbar circuit. The low-pass filter significantly lowers the let-through voltage of the device for short-duration pulses, and helps to spread the energy to more effectively utilize the transient voltage suppressor. The transient voltage suppressor limits the let-through voltage to a clamping level and provides indication to the crowbar circuit when it is no longer able to do so. Once the clamping level is no longer able to be maintained, the crowbar circuit draws enough current to trip an upstream protective device, such as a breaker or fuse.

Standoff ultra-compact micro-Raman sensors configured to receive Raman scattering from a substance are disclosed. A laser device may be configured to transmit a laser at a first wavelength. The laser may be expanded to a predetermined size, focused through a lens, and made incident on an unknown substance. A filter may reflect the laser and Rayleigh scattering from the substance, but may permit Raman scattering and laser-induced fluorescence from the substance. One or more lenses and/or filters may receive and pass the Raman scattering and/or laser-induced fluorescence to a light sensor. The received Raman scattering and/or laser-induced fluorescence may be compared to known fingerprints of substances to determine an identity of the substance. The wavelength of the laser, the width of the laser, and other parameters may be varied based on the distance between the standoff ultra-compact micro-Raman sensor and the substance.

An amorphous robot includes a compartmented bladder containing fluid, a valve assembly, and an outer layer encapsulating the bladder and valve assembly. The valve assembly draws fluid from a compartment(s) and discharges the drawn fluid into a designated compartment to displace the designated compartment with respect to the surface. Another embodiment includes elements each having a variable property, an outer layer that encapsulates the elements, and a control unit. The control unit energizes a designated element to change its variable property, thereby moving the designated element. The elements may be electromagnetic spheres with a variable polarity or shape memory polymers with changing shape and/or size. Yet another embodiment includes an elongated flexible tube filled with ferrofluid, a moveable electromagnet, an actuator, and a control unit. The control unit energizes the electromagnet and moves the electromagnet via the actuator to magnetize the ferrofluid and lengthen the flexible tube.
