Definitions

  • This invention relates to the operation of a computing device in a low power mode, and in particular to a method of operating a computing device in one or more low power modes which also protects the core functionality of the computing device.
  • the term 'computing device' includes, without limitation, Desktop and Laptop computers, Personal Digital Assistants (PDAs), Mobile Telephones, Smartphones, Digital Cameras and Digital Music Players. It also includes converged devices incorporating the functionality of one or more of the classes of device already mentioned, together with many other industrial and domestic electronic appliances.
  • Certain categories of computing devices are highly mobile; this means that they are designed to be used at any time in any place, even while on the move. Such devices invariably use batteries for power. This includes all mobile telephones and digital cameras, many mobile digital music players such as the Apple iPod, and many games machines such as the Nintendo Gameboy. It is usually possible to also operate such devices on mains power (via battery chargers or auxiliary low voltage power supplies) without consuming power from and therefore -" r draining the internal power battery source. However, such uses are generally considered to be atypical for such devices because their inherent portability and the ability to provide portable computing power is a major attraction for this type of device.
  • UPS Uninterruptible Power Supplies
  • Mobile phones normally restrict themselves to displaying a low power warning with an audible beep or other alarm. Some devices which normally emit audio adopt the reverse strategy and cease emitting audio when displaying low power warning.
  • UPS uninterruptible power supply
  • computing devices can, under circumstances of imminent battery failure, force an orderly shut down and power off of the device.
  • the perception behind this invention is that a computing device which is able to discriminate between functionality that has been or can be categorised as either essential or non-essential can also prolong battery life by progressively restricting access to the non-essential functionality of the computing device in dependence upon its available battery power.
  • mobile telephony handsets are now often used to provide some or all of the following examples of functionality (in no particular order or priority):
  • SMS short message services
  • GPS Global Positioning System
  • the present invention in its simplest form involves marking the making and receiving of telephone calls as essential functionality, with all other applications available on the device being marked as non-essential functionality. The user of the handset is then prevented from using any nonessential functionality whenever the power remaining in the battery on the device has reduced to less than a preset threshold.
  • Non-essential applications that are running at the time the threshold is reached are then closed down, ideally after a prompt giving the user a short period of grace equivalent to something like a small extra percentage of battery level to exit in a controlled fashion; and after the threshold has been passed, no nonessential applications are permitted to start or re-start, or to continue to run.
  • the essential functionality of the device is protected to the greatest extent possible and the time that the device is to remain operational on a single battery charge, in respect of this essential functionality, is maximised. It is preferable that most users are able to decide for themselves what is essential functionality, so a user can add (as examples) SMS or email to the list of applications that are permitted to run when this critical power level has been reached.
  • the list of applications can be selectively password protected; this would, for example, enable a parent providing a mobile phone to their child (so that an essential communication channel is available between the parent and child) can ensure that the battery does not become unnecessarily drained by the child using the handset for purposes considered as non essential to the parent, such as playing computer games. It is also possible that some manufacturers of devices may decide to preset such a scheme during production, as a default factory setting.
  • the scheme it is preferable for the scheme to allow for some hysteresis banding about the sensed battery levels to prevent unnecessary 'hunting' about any of the battery level thresholds. This is to ensure that if any battery level threshold is reached, whereby certain functions are enabled, those functions are not almost immediately or prematurely disabled again because the battery level drops back below the particular threshold because of the particular functionality that has just been enabled.
  • Such power-saving schemes may be linked to other information available to the phone; for example, it might be deemed appropriate to switch to a scheme wherein the ability to use the backlight as a torch becomes essential functionality during the hours of darkness, but if the battery power is closer to a critical level then the use as a torch is restricted to a pulsed light mode to further reduce power consumption.
  • this innovation can be further extended to power-consuming aspects of the user interface.
  • battery life may be selectively conserved by switching to a special low-power Ul which disables animations, uses simpler icons, reduced backlight level and the time for which the backlight is active, and disables all audio prompts (with the exception of those relating to essential applications such as ring tones).
  • the visible difference in the low power mode user interface has the additional advantage that it is made very clear to the user that the phone has reached a low power condition and needs recharging.
  • More refinements can include restricting access to power-hungry peripherals; so, for example, at a certain power level access to a hard disk is inhibited, but access to solid-state memory is allowed.
  • a preferred implementation of such a scheme should ensure that:
  • the computing device incorporates an Operating System (OS) which is responsible for launching and managing applications that run on the device;
  • OS Operating System
  • the OS is responsible for maintaining, managing and providing the necessary interfaces to the hardware on the device and one of these interfaces includes a means of retrieving the current battery level;
  • a key advantage of this invention is that it maximises the protection of the core functionality and purpose of a multi-function computing device, whatever that is selected to be. This can be important; for example, implementing this invention on a mobile telephone would help to ensure that calls to the emergency services are not made prematurely impossible because of over-enthusiastic use of non-essential functions, such as the playing of addictive games.
  • the invention also saves power by discouraging non-core uses for a multifunction computing device. Any measure that promotes power saving provides environmental benefits in general.

Abstract

L'invention concerne un dispositif informatique alimenté à partir d'une source de batterie interne, doté de la capacité de faire la différence entre une fonctionnalité qui a été ou peut être classée comme essentielle et une fonctionnalité qui a été ou peut être classée comme non essentielle. Le dispositif est de ce fait en mesure de prolonger sa capacité à exécuter sa fonctionnalité principale en limitant progressivement l'accès à une fonctionnalité non essentielle du dispositif informatique lorsque sa puissance de batterie diminue.
