Abstract: An unmanned aerial vehicle (UAV) may emit masking sounds during operation of the UAV to mask other sounds generated by the UAV during operation. The UAV may be used to deliver items to a residence or other location associated with a customer. The UAV may emit sounds that mask the conventional sounds generated by the propellers and/or motors to cause the UAV to emit sounds that are pleasing to bystanders or do not annoy the bystanders. The UAV may emit sounds using speakers or other sound generating devices, such as fins, reeds, whistles, or other devices which may cause sound to be emitted from the UAV. Noise canceling algorithms may be used to cancel at least some of the conventional noise generated by operation of the UAV using inverted sounds, while additional sound may be emitted by the UAV, which may not be subject to noise cancelation.

Abstract: Described is an unmanned aerial vehicle (“UAV”) payload receiving apparatus that may be secured to a side of a structure, such as a human residence, and positioned such that a UAV can deliver a payload into the UAV payload receiving apparatus without the UAV having to land or navigate into an area that includes objects that could be harmed by the UAV and/or harm the UAV. The UAV payload receiving apparatus may include a plurality of securing members for securing the UAV payload receiving apparatus to the structure. A top frame is coupled to the securing members, positioned in a substantially horizontal direction when the UAV payload receiving apparatus is secured to a structure, and forms an opening of a size sufficient for a payload to pass through when the payload is released by a UAV positioned above the UAV payload receiving apparatus. The UAV payload receiving apparatus also includes a payload retainer, such as a net or bag, that is coupled to and extends in a downward direction from the top frame.

Abstract: Virtual objects are located for display in a head-mounted display (HMD) to provide an augment reality view to an HMD wearer. An HMD wearer's total field of view (TFOV) is classified into two or more regions. Additionally, a field of view (FOV) for the HMD wearer is determined. The FOV is compared with the two or more regions of the HMD wearer's TFOV. Responsive to this comparison, virtual objects are determined for display based on a location of the FOV relative to the two or more regions of the HMD wearer's TFOV. The virtual objects may then be displayed by the HMD at an appropriate location.

Abstract: Virtual images are located for display in a head-mounted display (HMD) to provide an augment reality view to an HMD wearer. Sensor data may be collected from on-board sensors provided on an HMD. Additionally, other day may be collected from external sources. Based on the collected sensor data and other data, the position and rotation of the HMD wearer's head relative to the HMD wearer's body and surrounding environment may be determined. After resolving the HMD wearer's head position, the HMD wearer's total field of view (TFOV) may be classified into regions. Virtual images may then be located in the classified TFOV regions to locate the virtual images relative to the HMD wearer's body and surrounding environment.

Abstract: Described is a technology by which an entity's (e.g., a user's or group's) usage of a digital entertainment service is used to automatically generate an interactive, personalized three-dimensional visualization representing the entity's career on a digital entertainment service. Usage events are collected as profile information, which is processed to generate the visualization, as well as to automatically theme the user's experience. Filtering and prioritization of data within the profile information is performed based on the predicted degree of interest to the entity and to others; the entity may provide preference data to vary the automatically generated visualization and/or theme.
