Computer-implemented system and methods for secure package delivery

In some embodiments, a secure package delivery system and methods may include a remotely-controllable electronic door lock device accessible by in a system server, a delivery information device in communication with the system server, and a client device in communication with the system server. The delivery information device may provide delivery status information of a package to the system server. The remotely-controllable electronic lock device may enable or prevent access to a door at the location to which the package is to be delivered. The system server may, in response to receiving a notification that the package en route for delivery is proximate the delivery location and receiving a secure package delivery indicator associated the package recipient's account that indicates whether the package recipient has provided consent for a package delivery in a structure at the delivery location locked with an electronic lock without further instruction by the package recipient at a time of delivery. If the received secure package delivery indicator indicates the package recipient's consent for a package delivery in the structure without further instruction by the package recipient at a time of delivery, transmitting an access request signal for causing a lock control system associated with an electronic lock at an access door of the structure at the delivery location to cause the lock control system to unlock the lock. The system server may also be configured to communicate delivery completion information to the client device.

InactiveUS20100142418A1Decrease in communication efficiencyDifferent selectionWireless communicationDuplex signal operationComputer hardwareCommunications system
The object of the present invention is to provide a data communication system in which a communication scheme is switched without a decrease in communication efficiency.
In a data communication system including first and second devices that are capable of performing full-duplex communication and half-duplex communication via a set of channels connecting the first and second devices, the first device transmits, via the set of channels, to the second device a first communication flag indicating whether half-duplex communication is to be specified in accordance with a communication processing capability of the first device, the second device transmits, via the set of channels, to the first device a second communication flag indicating whether half-duplex communication is to be specified in accordance with a communication processing capability of the second device, and the first and second devices select either a full-duplex communication scheme or a half-duplex communication scheme depending on the first and second communication flags in compliance with a procedure predetermined between the devices and perform data communication in the selected communication scheme, the selected communication scheme conforming to the communication processing capability of each device.

Display apparatus

A display apparatus that displays an image on a retina of a user, the display apparatus comprising: an image output unit (100) which includes a light source (101, 110), a wavefront shape change unit (102, 109), and a scan unit (103, 108) and is configured to output display light for displaying the image; and a deflection unit (104, 107) configured to deflect, toward an eye of the user, the display light outputted by the image output unit (100). The deflection unit (104, 107) has a deflection characteristic of suppressing image distortion caused by a change in relative position of the deflection unit (104, 107) with respect to a pupil of the user.
