Abstract: 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.

Abstract: 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.

Abstract: In an example, an apparatus includes an electric current monitor circuit and a feedback sub-circuit. The electric current monitor circuit includes a comparator having an inverting input to measure a first voltage on a first side of a first resistor, a separate non-inverting input to measure a second voltage on a second side of the first resistor, and an output. The feedback sub-circuit feeds an input voltage back to the inverting input. The feedback sub-circuit includes a second resistor coupled to the inverting input and a Zener diode coupled between the output and the second resistor.

Abstract: Apparatuses, methods, systems, and arrangements facilitate the upkeep of an electronic device. In certain described implementations, one or more analyses and/or determinations may be completed with regard to one or more replaceable issues. If the replaceable issue(s) are determined to be deficient (including potentially deficient), then the electronic device may produce one or more upkeep-related items to facilitate an operator's upkeep thereof. Exemplary replaceable issues may be related to consumable item(s), maintenance items(s), ability items(s), etc. Exemplary upkeep-related items may include order-related items, reports, etc. Exemplary order-related items may include order forms, discount coupons and codes, network address and information combinations, etc.

Abstract: A system and methods combine images from various devices in a printing system and display an overall system image on the control panel of a printing device. Events in a printing system are associated with particular event codes. For example, an error event such as a paper jam in a printing device or other device coupled to the printing device is associated with a particular error code. When an event occurs, a printing device receives an associated event code. Based on the event code, the printing device merges images from one or more external devices with an image of itself. The merged image makes up an overall printing system image that is displayed on a control panel of the printing device. The system image provides information to a user about the nature and location of the event.
