Abstract: A marker system includes an enclosure with a controller therewithin. Emitters are electrically interfaced to the controller and include visible wavelength emitters and infrared wavelength emitters. The controller is configured to selectively initiate a flow of electric current though the visible wavelength emitters or through the infrared wavelength emitters causing the visible wavelength emitters or the infrared wavelength emitters to emit light and the light passes through the enclosure. There is at least one infrared detector, each of which is electrically interfaced to the controller and each of which is configured to detect infrared light that enters the enclosure. When the controller receives an electrical signal from any of the at least one infrared detector indicating reception of infrared light, the controller emits a signal to warn of the reception of infrared light (e.g., an audible signal, a vibration, a wireless signal, a wired signal).

Abstract: A method of synchronizing flashing between a plurality of marker system components mounted on a helmet includes receiving a signal from at least one global positioning satellite receiver, the signal comprising a time value. When the time value indicates illumination is needed, initiating illumination of at least one light emitting device of each the marker system components, thereby, synchronizing of the initiating of illumination to the time value for all marker system components.

Abstract: A safety switch includes an actuator that has a first possible actuator position and a second possible actuator position and a blocker that has a first possible blocker position and a second possible blocker position. The first possible blocker position overlaps with the second possible actuator position. The safety switch includes a device for generating an electrical signal representative of a current position of the actuator. When the actuator is in the first possible actuator position and the blocker is in the first possible blocker position, the blocker prevents movement of the actuator from the first possible actuator position to the second possible actuator position without first moving the blocker from the first possible blocker position to the second possible blocker position.

Abstract: A helmet-mounted marker system includes one or more coordinates of one or more danger zones in digital format and a mechanism for periodically determining a location of the helmet-mounted marker system. From the location, another mechanism determines if the location of the helmet-mounted marker system is within any of the one or more danger zones. If the location of the helmet-mounted marker system is within any of the one or more danger zones, there is a mechanism to notify a wearer of the helmet-mounted marker system.

Abstract: A marker system includes at least one emitter. The emitter(s) emit light responsive to a flow of electrical current there through. The marker system includes a device for acquiring an incoming signal and a circuit for processing the incoming signal. The circuit for processing the incoming signal monitors the device for acquiring the incoming signal to determine if the incoming signal includes any of a plurality of incoming Identification Friend or Foe (IFF) and/or munitions-targeting signals. The circuit emits one of a plurality of responses by sending electrical current selectively through the emitter(s) and/or other feedback devices based upon which of the plurality of incoming Identification Friend or Foe (IFF) and/or munitions-targeting signals is detected by the means for processing.

Abstract: A drop zone marker includes a parachute, a first light module connected to the parachute by a first length of cord and a second light module connected to the first light module by a second length of the cord. A ballast is connected to the second light module by a third length of the cord is provided for pulling downwardly the drop zone marker. The parachute is configured to include an integral packing/deployment bag within which all components of the drop zone marker are contained up until deployment.

Abstract: A marker system has a first section of an enclosure and a second section of the enclosure with a pivot rotatably connecting the first section to the second section. In such, the first section is adjustable from being in line with the second section to forming an arc with the second section, thereby conforming to multiple surface curvatures. There are several emitters within the enclosure and there is electronics (discrete electronics and/or a processor) for controlling the emitters responsive to user controls. For example, in a first mode, the emitters emit a light that is visible to the human eye through the enclosure and in a second mode; the emitters emit a light that is invisible to the human eye through the enclosure.
