An example image forming apparatus includes a control panel and a processor. The control panel includes a liquid crystal display, a touch screen, a microcontroller, a multiplexer, a coder-decoder, and a speaker. The processor is to control the speaker. Based on a selection of a diagnosis mode, the microcontroller is to interrupt the control of the output of the speaker by the processor, change a state of the multiplexer, and perform a diagnosis by controlling the speaker to output a sound based on receipt of an input on the touch screen.

Isolated diagnosis of source of error using control panel circuitry

In example implementations, an apparatus is provided. The apparatus includes a plurality of power outputs, a logic controller and a single switch. Each one of the plurality of power outputs is communicatively coupled to a respective current/power sensor. The logic controller is communicatively coupled to the respective current/power sensor of each one of the plurality of power outputs. The single switch is communicatively coupled to the logic controller and the respective current/power sensor of each one of the plurality of power outputs. Power to each one of the plurality of power outputs is controlled by the logic controller via the single switch.

Single switch electronic fuses with multiple power outputs

An example system includes a rectifying component to convert an alternating current (AC) signal into a direct current (DC) signal. The system also includes a filtering component. The filtering component determines that a plurality of AC cycle drops have occurred and will deactivate the AC signal in response to that determination. Furthermore, the system includes an isolating component. The isolating component consumes greater than a threshold level of power in one state and less than a threshold level of power in another state. The isolating component is operating in the state that consumes greater than a threshold level of power when the signal that indicates the AC voltage is at a level in which it may allow the device to operate safely and properly is deactivated.

Isolating electrical components

A device includes a current sensor, a first current monitor, and a second current monitor. The current sensor is to sense a current between an input node and an output node. The first current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a first threshold current for a period exceeding a threshold period. The second current monitor is to disconnect the input node from the output node in response to the sensed current exceeding a second threshold current greater than the first threshold current.

Devices including two current monitors

A power monitor circuit, includes a power delivery path including an input voltage, a first resistor, and a load. The power monitor circuit further includes a comparator to measure a voltage across the first resistor. The comparator includes an inverting input to measure a voltage on a first side of the first resistor, a non-inverting input to measure a voltage on a second side of the first resistor, a threshold input to receive a threshold input voltage level, and an output to generate a trip signal when the voltage across the first resistor meets the threshold input voltage input level. The power monitor circuit further includes a sub-circuit in series with the first resistor, the sub-circuit including a second resistor coupled to a Zener diode, the sub-circuit to feed the input voltage back into the inverting input of the comparator. A third resistor connected between the first resistor and the second resistor, divides down the input voltage, and a fourth resistor is connected between the sub-circuit and the threshold input of the comparator. The fourth resistor is to set a voltage at which the trip signal is generated.

Regulating an output power of a monitored electronic device

A method of determining a data rate of a high speed serially transmitted data stream comprises statistically examining edge timing characteristics of the incoming data stream. Based on the edge characteristics, a signature is identified that is associated with the edge characteristics. Based on the identified signature, a data rate at which the data stream is being transmitted is determined.

Object-oriented data storage. A system and method is disclosed for enhanced data storage. A system for object-oriented data storage may comprise an intelligent object editor capable of accessing data content and a destination storage device coupled to the intelligent object editor. The intelligent object editor can link associated information to data content to create a storage object. The storage object can then be stored to the destination storage device.

A read/write arrangement for a contact probe storage arrangement or the like, has a cantilever disposed with a medium which is movable relative to the cantilever. A device which is associated with one of the cantilever and the medium is configured to be responsive to changes in electrical field between the medium and the cantilever caused by a change in distance between the medium and the cantilever. A heater is disposed on the cantilever for heating the medium and for inducing localized topographical changes which represent bits of data. A circuit electrically interconnects both of the device and the heater.

A system comprises a storage controller for managing transfers of data between a host and storage memory; a data mover coupled to the storage controller handling data transferred between a host and storage memory; and a buffer coupled to the data mover for storing data being transferred. The storage controller modifies operation of the storage system based on status of the data transfer. An associate method comprises transferring data between a host and storage memory via a storage system, and dynamically adjusting operation of the storage system depending on status of the data transfer.

System having a storage controller that modifies operation of a storage system based on the status of a data transfer

Systems and methods of information transfer are disclosed. In one embodiment, the system may comprise a master device and a slave device coupled by a bus in which clock information is embedded in the data stream. Various flow control techniques may be used to compensate for differences in transfer rates supported by the master and slave devices. Two types of synchronization fields may be employed to establish and maintain clock acquisition. The master device may transfer information to the slave device using a sync field of a first type followed by a first data packet, and the slave device may respond to each data packet with a sync field of a second, different type, followed by a status ready field if no additional time is needed before receiving another data packet.
