Abstract: A nozzle receiver is to be arranged in a powder container used in an image forming apparatus. The nozzle receiver includes a nozzle receiving opening, in which a conveying nozzle for conveying powder supplied from the powder container is inserted in the image forming apparatus; an opening/closing member to open and to close the nozzle receiving opening; and a supporter to support the opening/closing member. The opening/closing member includes a sealing portion to seal the nozzle insertion opening. The supporter includes an end surface portion perpendicular to a moving direction of the opening/closing member. The projection area of the end surface portion in the moving direction of the opening/closing member is smaller than a projection area of the sealing portion in the moving direction of the opening/closing member.

Abstract: According to an embodiment, when a nozzle insertion member is detached from a powder container, an engaging portion and an engaged portion are disengaged from each other by resiliently displacing the engaging portion in a direction in which the engaging portion is disengaged from the engaged portion. Therefore, it is possible to reduce a stress applied to the powder container and the nozzle insertion member at the time of attachment and detachment of the nozzle insertion member. Consequently, it becomes possible to easily detach the nozzle insertion member from the powder container.

Abstract: In certain implementations, a presentation of a virtual counterpart of an action figure may be provided based on action figure state information obtained via wireless communication with the action figure. As an example, an action figure may be detected within a short wireless communication range of a computer system. A wireless connection between the computer system and the action figure may be established based on the detection. Action figure state information identifying a position of a moveable part of the action figure relative to another part of the action figure may be received at the computer system from the action figure via the wireless connection. The relative position may be related to a pose exhibited by the action figure. A virtual counterpart of the action figure may be presented based on the relative position such that the virtual counterpart exhibits the same pose as the action figure.

Abstract: In certain implementations, a software development kit to enable configuration of virtual counterparts of action figures or action figure accessories may be provided. As an example, the software development kit may enable a developer to associate a state or behavior of an action figure type with a virtual state or behavior of a corresponding virtual counterpart type in a virtual environment such that, when an action figure (of that type) exhibits the state or behavior, a corresponding virtual counterpart is caused to exhibit the virtual state or behavior in the virtual environment. The software development kit may, for example, enable the same state or behavior to be associated with different action figure types and/or different virtual states or behaviors such that, even when action figures of different action figure types exhibit the same state or behavior, their corresponding virtual counterparts may be caused to exhibit different virtual states or behaviors.

Abstract: In certain implementations, state information of an action figure may be provided via wireless communication. As an example, a device may be detected within a short wireless communication range of an action figure. A wireless connection between the action figure and the device may be established based on the detection. Sensor information may be obtained via one or more sensors of the action figure. Action figure state information identifying a position of a moveable part of the action figure relative to another part of the action figure may be generated based on the sensor information. The relative position may be related to a pose exhibited by the action figure. The state information may be provided to the device via the wireless connection. A virtual counterpart of the action figure may be presented based on the relative position such that the virtual counterpart exhibits the same pose as the action figure.

Abstract: In certain implementations, secured communication with an action figure or action figure accessory may be provided. As an example, a device may be detected within a short wireless communication range of the action figure or action figure accessory. A wireless connection may be established between the action figure or action figure accessory and the device based on the detection. A first key may be obtained. First encrypted information may be received from the device via the wireless connection, and processed based on the first key to determine a second key. An identifier associated with the action figure or action figure accessory may be obtained. Second encrypted information may be generated based on the second key and the identifier, and provided to the device via the wireless connection. The second encrypted information may be used to obtain a virtual counterpart of the action figure or action figure accessory.
