A system to detect obstacles includes a power beam transmission circuit, a power beam reception circuit arranged to receive a power beam from the power beam transmission circuit, an emitter module, and a detector module arranged to distinguish between a first characteristic and a second characteristic. The emitter module includes a first emitter arranged to emit a first signal having the first characteristic, the first signal emitted in proximity to the power beam, and a second emitter arranged to emit a second signal having the second characteristic, the second characteristic different from the first characteristic. The detector module includes a first detector arranged to respond to the first signal emitted by the first emitter, the detector module being arranged to determine when an obstacle is in or near a line-of-sight transmission path between the first emitter and the first detector.

Light curtain safety system

Embodiments are directed towards a safety system that can be used with a high-flux power beam, such as in wireless power transmission. The system includes a transmitter that generates and transmits a power beam and a receiver that receives the power beam. A plurality of sensors is configured to independently detect if an object is near, impeding, or about to impede (i.e., impinging) the power beam. Each of the plurality of sensors is configured to detect the object at different distances between the transmitter and the receiver. A controller triggers the transmitter to stop generating the power beam when any one or more of the plurality of sensors detects the object or a combination of the plurality of sensors detects the object. The controller triggers the transmitter to re-generate and transmit the power beam when each of the plurality of sensors fails to detect the object.

Multi-layered safety system

A system to detect obstacles includes a power beam transmission circuit, a power beam reception circuit arranged to receive a power beam from the power beam transmission circuit, an emitter module, and a detector module arranged to distinguish between a first characteristic and a second characteristic. The emitter module includes a first emitter arranged to emit a first signal having the first characteristic, the first signal emitted in proximity to the power beam, and a second emitter arranged to emit a second signal having the second characteristic, the second characteristic different from the first characteristic, the second signal emitted in proximity to the first signal. The detector module includes a first detector arranged to respond to the first signal emitted by the first emitter, wherein the detector module is arranged to determine when an obstacle is in or near a line-of-sight transmission path between the first emitter and the first detector.

A power beaming system includes a power beam reception unit and a power beam transmission unit. The power beam reception unit includes a power conversion array, such as a photovoltaic array, arranged to capture at least a portion of a power beam, and a power supply circuit arranged to convert flux from the captured portion of the power beam to electric power. The power beam transmission unit includes a power beam transmitter circuit to transmit a low-flux search beam during a first time window, and further arranged to transmit a high-flux power beam during a second time window. The power beam transmission unit also includes a location detection circuit arranged to identify a location of the reception unit based on the power beam transmitter circuit transmitting the low-flux search beam during the first time window.

Locating power receivers

A projectile includes a component that is highly reflective and configured to reveal the projectile's trajectory when the projectile is fired from a gun and electromagnetic radiation is directed toward the projectile. With the reflective component, one can more easily limit the visibility of the projectile to areas from where the projectile was fired because the reflective component is passive, not active. As the projectile moves down range, the areas behind the projectile are typically where a shooter and/or spotter for the shooter are located, not where an enemy combatant is located. Thus, the trajectory of the projectile is revealed to the people who can use the information to adjust their fire, and remains hidden from the people who could use the information to locate the shooter.
