A control circuit includes a memory interface and a power interface. The control circuit is configured to: read out identifiers and voltage values from a memory via the memory interface, the memory storing the identifiers and the voltage values associated with the identifiers, the identifiers identifying actuators for jetting liquid, the voltage values corresponding to values of voltages to be supplied to the actuators; based on the voltage values, associate each of the identifiers with one of power circuits; detect whether failure occurs in any of the power circuits via the power interface communicated with the power circuits each changeable in output voltage; and based on detection of the failure occurring in any power circuits, associate specified identifiers with a non-failure power circuit in which the failure does not occur, the specified identifiers associated with a failure power circuit in which the failure is detected.

Control circuit, ink-jet head system, and control method

In response to receiving process-request information from an external device after starting operation by second power, a communication controller is configured to perform: a first supplying process of controlling a second power supply to supply the second power to a first communication node; a first data communication process of performing data communication with the first communication node after starting the first supplying process, wherein the first data communication process includes receiving process-related information from the first communication node; a determining process of, after finishing the first data communication process, determining whether data communication with a second communication node is necessary, based on the process-request information and on the process-related information; and a second supplying process of controlling the second power supply to supply the second power to the second communication node, in response to determining in the determining process that data communication with the second communication node is necessary.

Communication apparatus configured to perform non-contact communication with external device

A communication controller controls non-contact communication with an external device via an antenna while at least one of first and second power is supplied. A first circuit electrically connects a first power supply to a communication node. A second circuit electrically connects a second power supply to the communication node. The first circuit includes a first electrical component configured to prevent second power from being supplied to a particular target electrically connected to the first power supply while the second power is supplied to the communication node. The communication controller communicates with the communication node in a certain data communication method while the second power is supplied to the communication node. In response to reception of electric power from the external device via the antenna, the second power supply supplies the second power to the communication controller, and supplies the second power to the communication node through the second circuit.

An image processing apparatus including a wireless communication unit, an image processing unit, and a controller configured to establish a wireless connection to perform wireless signal communication between the wireless communication unit and an external device, acquire a reception intensity of a wireless signal received from the external device via the wireless communication unit, determine whether the reception intensity is more than a threshold value, when determining that the reception intensity is more than the threshold value, control the image processing unit to execute an image processing instruction received from the external device via the wireless communication unit, and when determining that the reception intensity is not more than the threshold value, transmit an instruction to display a warning on the external device, to the external device via the wireless communication unit, without controlling the image processing unit to execute the image processing instruction.
