Abstract: An example method may include receiving, from a client computing device, an indication of a target drop-off spot for an object within a first virtual model of a first region of a delivery destination. A second virtual model of a second region of the delivery destination may be determined based on sensor data received from one or more sensors on a delivery vehicle. A mapping may be determined between physical features represented in the first virtual model and physical features represented in the second virtual model to determine an overlapping region between the first and second virtual models. A position of the target drop-off spot within the second virtual model may be determined based on the overlapping region. Based on the position of the target drop-off spot within the second virtual model, the delivery vehicle may be navigated to the target drop-off spot to drop off the object.

Abstract: An example apparatus includes a first disk that is rotatable and has a plurality of electro-permanent magnets disposed in a radial array on a surface of the first disk; and a second disk rotatably mounted adjacent to the first disk such that a gap separates the second disk from the first disk, where the second disk has a plurality of ferromagnetic elements disposed in respective radial array on a respective surface of the second disk. Applying an electric pulse to at least one electro-permanent magnet of the plurality of electro-permanent magnets changes a magnetic state of the electro-permanent magnet, thereby (i) generating an external magnetic field that traverses the gap between the first disk and the second disk and interacts with a corresponding ferromagnetic element of the plurality of ferromagnetic elements, and (ii) causing the second disk to rotate as the first disk rotates.

Abstract: Disclosed herein is a method of determining a location of a wireless power receiver. The method involves determining a first coupling coefficient between a transmitter and a receiver coupled via a wireless resonant coupling link, where the receiver is disposed at a first location. Further, the method involves receiving, by the transmitter, kinematic data generated by a sensor coupled to the receiver. Yet further, the method involves determining, based on the kinematic data and the first coupling coefficient, the first location.

Abstract: The present technology provides power generation using thermoradiative cell (TRC) structures, which generate electricity by radiating heat from a hotter area/body to a cooler area/body. The TRC structures may be used in conjunction with photovoltaic (PV) cells on a common platform as a power generation system. In some scenarios, the platform may be a high altitude platform (HAP). Here, the TRC structures may be arranged or aligned to radiate heat towards space or otherwise in a direction generally away from the Earth's surface. The electricity generated by the TRC structures is provided to a power supply, for instance to recharge batteries of the power supply. The TRC structures may be intersubband TRC structures. In some configurations, the TRC structures are co-located on the same side of a panel as the PV cells. In other configurations, the TRC structures are remote from the PV cells.

Abstract: A method for fabricating a semiconductor device includes generating a wafer by generating an N-type semiconductor layer and an active region on the N-type semiconductor layer. The N-type semiconductor layer is located on a first side of the active layer. One or more oxidizing layers are generated along with a P-type semiconductor layer generated on a second, opposite side of the active layer. The wafer is etched to expose a surface of each oxidizing layer. Oxidation of a first region of each oxidizing layer is allowed, where a second region of each oxidizing layer remains non-oxidized.

Abstract: Disclosed herein are systems and methods for providing wireless power. The method includes determining a route in an area for a charger vehicle, where the charger vehicle includes a primary wireless power transceiver. The method further includes determining a schedule according to which the charger vehicle travels along the route. The method also includes determining a number of repeater vehicles to deploy in the area to extend a range of the primary transceiver of the charger vehicle. Further, the method includes deploying the determined number of repeater vehicles into the area. Furthermore, the method includes coupling each of the repeater vehicles to the charger vehicle via a respective first wireless resonant coupling link.

Abstract: Described herein are methods and systems for facilitating a wireless power handover. In particular, a controller may cause a first transmitter to provide electrical power to a receiver. The controller may then determine that a handover condition is met and may responsively facilitate a handover to a second transmitter. During this handover, the controller may engage in a phase-determination process to determine first and second phases at which the first and second transmitters should respectively provide electrical power to the receiver. Once determined, the controller may then cause the first and second transmitters to respectively provide electrical power to the receiver at the first and second phases and at substantially the same time. Subsequently, the controller may cause the first transmitter to no longer provide electrical power to the receiver and the second transmitter to continue to provide electrical power to the receiver, thereby completing the handover.

Abstract: A method of fabricating a light emitting diode (LED) includes forming an active region structured to emit ultraviolet (UV) light and disposed between a first n-type semiconductor region and a first p-type semiconductor region. The method also includes forming a tunnel junction, where the first p-type semiconductor region is disposed between the active region and the tunnel junction, and where the tunnel junction is electrically coupled to inject charge carriers into the active region through the first p-type semiconductor region. A second n-type semiconductor region is also formed, where the tunnel junction is disposed between the second n-type semiconductor region and the first p-type semiconductor region.

Abstract: A light emitting diode (LED) to emit ultraviolet (UV) light includes a first n-type semiconductor region and a first p-type semiconductor region. The LED also includes an active region disposed between the first n-type semiconductor region and the first p-type semiconductor region, and in response to a bias applied across the light emitting diode, the active region emits UV light. A tunnel junction is disposed in the LED so the first p-type semiconductor region is disposed between the active region and the tunnel junction. The tunnel junction is electrically coupled to inject charge carriers into the active region through the first p-type semiconductor region. A second n-type semiconductor region is also disposed in the LED so the tunnel junction is disposed between the second n-type semiconductor region and the first p-type semiconductor region.
