  • Patent number: 10353388
    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: The disclosure relates to a system having an electric machine with a superconductive component cooled using a cryogenic liquid, and in particular to the full utilization of the refrigeration power available from vaporization of the cryogenic coolant. The system also has a fuel cell, in which an operating medium may be reacted to provide electrical energy. The coolant is fed in liquid form to the superconductive component to cool the component, utilizing the vaporization enthalpy of the coolant. The coolant is then fed in gaseous form to a further component of the machine to cool the component, utilizing the heating enthalpy of the coolant. The now heated coolant is fed to the fuel cell, which uses the coolant supplied to the fuel cell as an operating medium and reacts it.

  • Publication number: 20190041852
    Abstract: An example system includes a delivery vehicle, a sensor connected to the delivery vehicle, and a control system that determines a delivery destination for an object. The control system receives sensor data representing a physical environment of at least a portion of the delivery destination and determines a drop-off spot for the object within the delivery destination by way of an artificial neural network (ANN). The ANN is trained to determine the drop-off spot based on previously-designated drop-off spots within corresponding delivery destinations and includes an input node that receives the sensor data, hidden nodes connected to the input node, and an output node connected to the hidden nodes that provides data indicative of a location of the drop-off spot. The control system additionally causes the delivery vehicle to move to and place the object at the drop-off spot.

  • Publication number: 20190044470
    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.

  • Patent number: 10164476
    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.

  • Publication number: 20180323338
    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.
