An image forming apparatus is provided. The image forming apparatus includes a communicator configured to receive printing data, an image former configured to print the received printing data, and at least one processor configured to, in response to receiving a request for connection setting information from the user terminal apparatus, control the communicator to transmit the connection setting information to the user terminal apparatus.

Provided is a management system that, recovers the image forming apparatus to being online by remote control from the management server. The image forming apparatus management system includes a message-receiving apparatus for receiving control instructions from the management server via a communication path (mobile telephone network) that is separate from a network. The management server detects an image forming apparatus of which the connection with a server-communication unit becomes offline as an offline apparatus. Then, the management server transmits a control instruction to the message-receiving apparatus via the communication path for causing the offline apparatus to recover the connection with the server-communication unit to online. The management-target image forming apparatuses are connected to the message-receiving apparatus, and based on control instruction received by the message-receiving apparatus, communicate with the server-communication unit via the network and recovers the connection to online.

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 that receive 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, wherein 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.

An electronic device includes a power unit that accommodates a battery; a communication unit that wirelessly communicates with an external device; and a printer unit that prints print data obtained by the communication unit on a recording paper, wherein an outer appearance of the electronic device is a cylindrical shape.

The present invention provides a technique that enables an image communication apparatus capable of performing voice communication and T.30 in-band FAX communication over the IP network to positively detect a CNG signal and achieve switching to FAX reception in the answerphone connection mode and the FAX/TEL-switching mode. The communication apparatus includes a MODEM that controls facsimile communication and a SLIC that controls a telephone. A selector includes switches for connecting the IP network and the MODEM, and switches for connecting the IP network and the SLIC. A CPU controls the switches of the selector such that signals from the IP network are supplied to both of the MODEM and the SLIC.

A system and method for network device oversight includes a processor on a network client configured to generate a network probe via a network interface. Network configuration data corresponding to a configuration of a plurality of network devices is stored in a memory. The processor receives response data from an associated network device responsive to the probe and the processor updates the network configuration, device configuration, device status or user data in accordance with the response data.

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 processing apparatus includes a processing unit, an instruction unit, a detection unit, and a suspension unit. The processing unit performs a process that is predetermined. The instruction unit gives an instruction to start the process to the processing unit. The detection unit detects a sound in the vicinity of the processing apparatus. The suspension unit suspends the process in a case where the detection unit detects a predetermined sound while the processing unit is performing the process.
