A light filed (LF) display system for displaying holographic performance content (e.g., a live performance) to viewers in a venue. The LF display system in the venue includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a performance volume (e.g., a stage) for displaying the performance content in the venue. The array of LF modules displays the performance content to viewers in viewing volumes. The LF display system can be included in a LF presentation network. The LF presentation network allows holographic performance content to be recorded at one location and displayed (concurrently or non-concurrently) at another location. The LF presentation network includes a network system to manage the digital rights of the holographic performance content.

A fax and print method includes steps of providing a first fax device, a second fax device and a portable communication device, allowing the first fax device to send a fax password and a document to the second fax device and a data message and a text message corresponded to the fax password to the portable communication device, allowing the portable communication device to receive the text message and the data message, allowing the second fax device to receive the fax password and the document, generating a wireless connection between the portable communication device and the second fax device, judging if the text message is matched with the fax password, and printing the document when the result of the judgement is True. Therefore, the risk of being stolen is reduced through a transmission without the internet. The user does not have to remember any password. The user experiences are enhanced.

An image forming system to control an image forming apparatus by using a messenger application, a mobile device, and a method are provided. The image forming system includes a mobile device to activate a chat user interface to interface with an account of the image forming apparatus on the messenger application, and sending user messages to control a printing function of the image forming apparatus, a cloud server to receive the user messages from a messenger server, providing response messages of the account of the image forming apparatus in response to the user messages, and communicating with the mobile device in a conversational manner, thus controlling the printing of the image forming apparatus, and an image forming apparatus whose printing is controlled by the cloud server based on the user messages or providing monitoring information of a current status.

An image connection system including an information gathering unit that gathers information on an image to be captured, an image requesting unit that requests the capture of an image from at least one mobile communication device at a predetermined location for a predetermined fee, an image routing device that routes an image form at least one mobile communication device to the requesting device.

A communication device is configured to relay or capture communication performed between a plurality of information processing apparatuses. The communication device includes circuitry configured to: generate a log indicating a record of the communication performed between the plurality of information processing apparatuses; store the generated log in a memory; infer which one of a normal mode or and energy saving mode an operation state of a transfer destination device is, based on content of communication performed between a transfer destination apparatus and another information processing apparatus in a predetermined latest period; and controls transfer of the log based on a result obtained by inferring by the circuitry, so that the circuitry transfers the log to the transfer destination apparatus in a case where the result indicates the normal mode, and the circuitry postpones a transfer of the log in a case where the result indicates the energy saving mode.

A printing apparatus comprises a plurality of sending units that respectively send signals; a plurality of receiving units provided on a printhead and respectively corresponding to the plurality of sending units, the plurality of receiving units receiving signals via a signal line; and a phase adjustment unit that, based on a phase difference of a plurality of signals respectively received by the plurality of receiving units, controls and outputs a delay of the plurality of signals. Each of the plurality of sending units sends a phase adjustment signal for phase adjustment to be performed by the phase adjustment unit, and a phase adjustment signal sent by a first sending unit includes a signal having a coordinate phase and an opposite phase with respect to a phase adjustment signal sent by a second sending unit.

In a server, a memory stores first correlation information for correlating first group identification information with both first device information assigned to a first communication device and second device information assigned to a second communication device. A first group includes the first communication device and the second communication device. In a case where device information matching the first device information and authentication information matching the first authentication information are received from the first communication device, the processor transmits to the first communication device a second file generated using a first file which is stored correlated with the first authentication information in the memory. In a case where device information matching the second device information and authentication information matching the first authentication information are received from the second communication device, the processor transmits to the second communication device the second file.
