A secure communication system includes a wearable secure communication device which may receive and transmit information via a network. A wearable secure communication device may include a noise generator. The wearable secure communication device further includes a power input connection. Additionally, the wearable secure communication device may include a communication processor. The secure communication system and the wearable secure communication device may provide access to a secure information exchange system.

An impact sensor has a hollow container with a spring extending therethrough. A liquid is present in the cavity. The spring biases opposing valve balls to a closed position, preventing dye that is located exterior of the cavity from entering the cavity. When a force applied to the sensor exceeds a first predetermined value, the spring is compressed or displaced, allowing at least one of the valve balls to move from the closed position to an open position, thereby allowing the dye at the moving valve ball to pass into the cavity, mixing with the liquid and providing a visual indication of the exceeded force upon the sensor.

The invention relates to a protective helmet, and in particular, to a protective motorcycle helmet, comprising an antenna (1) for radio transmission, an outer shell (2) for distributing impact forces, an inner layer (3), which is accommodated by the outer shell (2), for damping impact forces, and a socket (4), which is firmly connected to the outer shell (2), for contacting a digital device (5) for wireless communication, wherein the socket (4), when contacting the digital device (5), electrically connects the latter to the antenna (1) for wireless communication. The protective helmet is characterized in that at least a partial layer of the outer shell (2) is disposed between the antenna (1) and the inner layer (3).

A signaling device is intended to be worn by a driver or rider of a land vehicle or intended to be mounted on such a vehicle, the vehicle preferably being a two-wheeled vehicle. The signaling device includes an accelerometer, an assembly of electrochemical batteries, a first light source, a wireless communicator intended to emit a warning signal, and a control unit. The control unit is intended to activate: the light source when the accelerometer measures a deceleration greater than or equal to a first predetermined deceleration threshold; and the communicator when the accelerometer measures a deceleration greater than or equal to a second predetermined deceleration threshold.

The disclosure provides conspicuity devices and methods. A first embodiment includes a glove with at least one elongate lighting device adapted and configured to admit light having an advantageous spectral energy distribution. Additional articles of clothing are provided herein for enhanced conspicuity, such as for emergency workers and athletes.

A communication helmet includes a helmet, a fixing belt, and a speaker module. The helmet has a head cavity for protecting a human head. Such helmet may be any known or new types of helmets for protecting soldiers, riders, policemen, working men in architecture building or in another engineering facilities, or for any other purposes and uses. The fixing belt has two belt ends connecting to two sides of the helmet. The fixing belt and the helmet together form a head container for fitting the human head.

A helmet with video acquisition device and display, comprising a helmet shell on which at least one video acquisition device is fixed, and a display arranged at one end of a front piece of the helmet; further comprising elements to allow the movement of the display laterally with respect to the active position in which the display is arranged completely in front of the eyes of a user.

The hard hat with integrated electronic systems is a hard hat comprising a shell, headband, sweatband, suspension harness, and size adjustment ratchet and knob. The hard hat also comprises electronics, which allow the user to listen to radio broadcasts, determine the time, receive and initiate mobile phone calls, issues voice commands to a paired device, or combinations thereof. A pair of audio transducers mounted adjacent to the ears allows the user to hear radio broadcasts and mobile phone audio. A microphone mounted on the control panel allows the user to talk during a mobile phone call or speak voice commands. A microprocessor within the hard hat controller manages devices and routes signals. A control display and operator controls accessible on the exterior side of the hard hat allows the user to change settings and pair the hard hat with a smart phone.

A conductive assembly (10) includes a conductive fabric core (12) which includes at least one electrically conductive element woven with the fabric core, optionally first and second impermeable layers (14, 16) enveloping the fabric core (12), first and second spacer layers (18, 20) overlying or within the impermeable layers (14, 16) and first and second conductive shield or screen layers (22, 24) overlying the spacer layers. The shield layers are electrically coupled together in the preferred embodiment for electromagnetic shielding. The spacer layers (18, 20) provide a stable and uniform spacing between the shield or screen conductors (22, 24) and the conductive fabric core (12).
