The present technology relates to a display apparatus, a display control method, a portable terminal apparatus, and a program capable of representing various states of an apparatus in a limited region.

A television receiver includes a display unit that displays a predetermined image, a communication unit that performs communication of image data with another image display apparatus, an indicator unit that is disposed at at least a part of surroundings of the display unit and includes an indicator which is turned on with predetermined luminance, and a control unit that turns on the indicator so as to correspond to a transmission operation of the image data in another image display apparatus. The present invention is applicable to, for example, a display apparatus such as a television receiver.

A storage device configured for connection with a host includes; an output unit configured to provide at least one storage device operating state indication to a user, an input unit configured to accept at least one user input, a main memory configured to temporarily store data received from the host, a storage configured to store the data in non-volatile memory space, and a controller configured to execute a backup operation in response to a user input accepted by the input unit, transfer data from the main memory to the storage during the backup operation, and provide a storage device operating state indication through the output unit during execution of the backup operation.

An information handling system may include one or more illuminable icons to present information to a user of the system, such as information regarding a status of the information handling system. An illuminable icon may be lit by a plurality of light sources, and light from the plurality of light sources may be diffused across the illuminable icon by a light guide film. Some illuminable icons may have multiple portions that may be separately illuminated to convey different information to a user. An isolation block may prevent light from light sources configured to illuminate one portion of an illuminable icon from illuminating other portions of the illuminable icon. Thus, light for illuminating icons of an information handling system may be diffused and/or blocked to enhance aesthetic appeal of the icons and to prevent user confusion that may result from bleeding of light from one portion of an illuminable icon to another and/or uneven illumination of an icon.

An electronic device such as a voice-controlled speaker device may have a housing. A speaker and other input-output components and control circuitry may be mounted within the housing. Light-emitting components may emit light that passes through a curved upper top cap portion or other housing structure. The light-emitting components may be interconnected using a flex circuit on a curved substrate or may be mounted on a planar circuit board. A subset of the light-emitting components may be rotated to improve color balance. Optical structures such as light guides, lens, microlenses, and/or a diffuser layer may be disposed over the light-emitting components to promote light mixing, to reduce hotspots, and to improve contrast on the top cap. The diffuser layer may be suspended using a support structure having baffle members to constraint the angular spread of the emitted light. Illuminated or persistently visible glyphs may be displayed in or near the top cap portion.

An information handling system may include at least one processor and a plurality of indicator lights. The at least one processor may be configured to detect a fault condition associated with a particular information handling resource located at a particular physical location, and cause at least some of the plurality of indicator lights to be illuminated in a determined sequence based on the physical location, wherein the determined sequence is configured to cause a dynamic visual illumination that is directed toward the physical location.

A fault content identification device 40 identifies details of a fault of a power supply control system in a short time by including: a detection unit 41 which, while a power supply control processing for turning on or turning off a power supply device 60 that supplies power to a main device 50 is in progress, detects that a value indicated by a power supply sequence signal generated by the main device 50 or the power supply device 60 and having a value that transitions in accordance with a prescribed specification, transitions to a value indicating non-conformance to the prescribed specification; and a generation unit 42 for generating information that indicates details of the power supply control processing performed at a timing when the detection unit 41 detects that the value indicated by the power supply sequence signal transitions to the value indicating non-conformance to the prescribed specification.

An activity-light-based parameter reporting system includes a storage device that is coupled to a storage device activity light. The storage device includes a parameter reporting engine that monitors a parameter associated with the storage device, and determines whether a rate of change of the parameter has exceeded a reporting rate of change. In response to determining that the rate of change of the parameter has exceeded the reporting rate of change, the parameter reporting engine drives the storage device activity light via at least one activity light parameter reporting signal that is configured to report the parameter. A controller monitors the driving of the storage device activity light by the parameter reporting engine, and identifies a parameter value of the parameter via the at least one activity light parameter reporting signal used by the parameter reporting engine to drive the storage device activity light.

Systems, apparatuses and methods may provide for technology that includes a solid state drive (SSD) having an enclosure, a non-volatile memory (NVM) device, a device controller coupled the NVM device, a capacitor, a backup voltage line coupled to the capacitor, and a safety assembly. The safety assembly may include a timer circuit including an input node coupled to the backup voltage line, a reset node, and an output node, an indicator circuit coupled to the output node of the timer circuit, and a temperature comparator circuit coupled to the reset node of the timer circuit, wherein if a temperature of the enclosure exceeds a threshold while a backup voltage is present on the backup voltage line, the temperature comparator circuit causes the timer circuit to trigger light pulses from the indicator circuit.

In one example in accordance with the present disclosure, a computing device is described. The computing device includes a housing and a light source to illuminate through a window in the housing. The computing device also includes a controller. The controller determines a usage level of a processor of the computing device. The controller also adjusts a characteristic of the light source based on a determined usage level of the processor.

Techniques for persistent crash logging. The techniques may include making, by a monitor, a first determination that an event information file exists in a volatile storage device location in a volatile storage device. The first determination may be made after an agent event occurs. The techniques may also include performing, by the monitor, an action on a portion of the event information file to obtain a uniquely identifiable filename portion and writing, by the monitor, an event information file copy to a non-volatile storage location in a non-volatile storage device. The techniques may also include, after writing the event information file copy to the non-volatile storage location is complete, renaming, by the monitor, the event information file copy to a uniquely identifiable filename comprising the uniquely identifiable filename portion.
