A dual-use electromagnetic beam system may be used as a remote power delivery system when not needed as an offensive weapon. For example, a system for disabling or destroying uncooperative or enemy assets such as UAVs or ground vehicles may be used during “down time” to provide power to assets that are separated from prime power sources by distance or by logistics.

A fence apparatus for handling a workpiece and resting on a support surface includes a rigid rectanguloid base, a top side of which includes a plurality of parallel guide slots. A bottom side includes at least three height-adjustable feet. A fence assembly includes an adjustable fence bracket and a fence. In some embodiments a top edge of the fence includes one of the guide slots, and the flip stop includes one of the guides for cooperating therewith to allow the flip stop to slide along the top edge of the fence. The flip stop may further include a removable pusher bar extending parallel to the fence for pushing the workpiece close to the tool. Two side L-brackets are each adapted for fixing with sides of the base and for fixing with the support surface. The fence apparatus is fully reversible from left to right.

Certain exemplary embodiments can provide a system, which comprises base and auxiliary multi point power chargers. The base multi point power charger is coupleable to an electrical energy source. The multi point power chargers are constructed to emit a plurality of directional beams. Each of the plurality of directional beams is directable toward a determined direction of an electronic device that is chargeable via the multi point power charger. The electronic device is comprised of the auxiliary multi point power charger.

Certain exemplary embodiments can cause an electronic device to charge or be remotely powered via a device. The device comprises a wireless transceiver. The device is constructed to: identify an electronic device in proximity to the device; automatically add, hand off or remove the electronic device to/across/from the network; and automatically determine a charge or remote power level of the electronic device.

A radio frequency (RF) front end device has a signal traveling from a first antenna to a second antenna in an uplink path and a signal traveling from a third antenna to a fourth antenna in a downlink path. The device is under the control of automatic on/off controller (AOOC) which upon receiving a signal indication from a receive signal detector and amplifier (RSDA) turns on the operations of power amplifier (PA) and simultaneously turns off a low noise amplifier (LNA). This LNA is turned off when the power amplifier is turned on to prevent uplink path and downlink path forming a feedback loop which would result in oscillation, noise and interference.

An example method performed by a wireless-power-transmitting device that includes an antenna array is provided. The method includes radiating electromagnetic waves that form a maximum power level at a first distance away from the antenna array. Moreover, a power level of the radiated electromagnetic waves decreases, relative to the maximum power level, by at least a predefined amount at a predefined radial distance away from the maximum power level. In some embodiments, the method also includes detecting a location of a wireless-power-receiving device, whereby the location of the wireless-power-receiving device is further from the antenna array than a location of the maximum power level.
