Abstract: Examples provide an authentication system for authorizing third-party pickup of items. An authentication controller obtains a user-generated token. The user-generated token is associated with an item to be picked up by a third-party user. The authentication controller creates a machine-generated token. The machine-generated token is transmitted to the third-party user. Upon receiving a request to pick up the item from the third-party user, the authentication controller compares tokens provided by the requesting third-party with the user-generated token and the machine-generated token. If the third-party provided tokens are valid, the requesting third-party is authorized to pick up the item and the request is accepted. The item is released to the authorized third-party requester. The item may be released via an item pickup kiosk or a locker system. If the tokens are invalid, the third-party request to pick up the item is rejected. A notification is sent to the user.

Abstract: A control circuit detects a present navigation concern within a physical boundary such as a building and augments the presentation of a piloted vehicle's pilot's field of view to include cautionary imagery regarding the present navigation concern. Examples of navigation concerns include but are not limited to a risk of colliding with another piloted vehicle, human activity in the physical boundary, and a blocked-passageway state of concern. Examples of cautionary imagery include but are not limited to an image of a STOP sign, an image of a traffic light, and an image of a barrier.

Abstract: A system and method for identifying which of several candidate service transformers is powering a specific service point an electrical distribution grid are disclosed. An audio-frequency electrical signal, the detection signal, is injected onto the power line at the service point via a meter socket or electrical outlet. The Transmitter for the detection signal may be a portable device or it may be incorporated into an electrical meter. The audible or mechanical resonance caused in the service transformer by the detection signal is detected and recorded using an accelerometer or directional microphone in a Receiver. A variety of methods for fixing the Receiver at or in proximity to the service transformers are disclosed in order to adapt to variations in the siting and housing of service transformers. A variety of mechanisms and methods for collecting detection events are disclosed.
