Definitions

  • the present invention relates to input devices for computer systems and, more specifically, to keyboards connectable to multiple devices wirelessly or by wires.
  • Smartphones are normally provided with very small keyboards that are too small for conventional 'full hand' typing. Consequently, users are forced to type with their thumbs or with a single finger, which is very slow.
  • accessory keyboards exist that can connect to smartphones. These accessory keyboards may be wired or wireless. Wireless keyboards are powered by batteries whereas wired keyboards are powered from AC mains.
  • accessory keyboards may be of assistance in obviating the need to type into a smartphone, it is often not convenient or efficient to provide a large separate keyboard for only occasional use with a very small phone.
  • Park et al. (US 5,861 ,822) discloses a battery-powered wireless keyboard that can also act as a wired keyboard to a single host computer. When operating as a wired keyboard, the wireless connection is automatically severed to conserve power. However, the battery- powered wireless keyboard of Park et al cannot connect to more than one device.
  • Park et al. (US 6,211 ,862) discloses a battery-powered wireless keyboard that recharges during wired operation and includes means for identifying the host computer during wireless operation, to ensure that the wireless connection is to the same computer as the wired connection.
  • Amro et al. discloses a battery-powered infrared wireless keyboard that connects wirelessly to multiple computers. Connections are established by aiming the keyboard's infrared emitter at the infrared receiver of the desired computer and pressing a button. If line-of-sight is not maintained, the connection is broken. Alternate embodiments allow for other wireless communications methods, via a single wireless emitter. In all cases, there is a delay when the emitter disconnects from one receiver and then establishes a connection with another receiver.
  • Silvester (US 7,336,602) discloses an apparatus and method for a battery-powered device connected via a wireless Bluetooth interface to switch to a wired interface when the error rate from radio interference exceeds a pre-determined threshold. In both wired and wireless modes, Silvester requires that the device connect to a single host computer.
  • an input device such as a keyboard
  • a host device such as a computer
  • at least one further device such as a smartphone or tablet.
  • the input device preferably is connected to the computer via a wired connection and includes a wireless module for allowing the keyboard to maintain simultaneously connections to both the computer and the further device, so that switching between them is instantaneous. This is made possible by the fact that the wired connection provides constant power to the wireless module, so it never needs to disconnect or enter sleep mode to save power. Also by providing a wireless module, many different models of smartphone, tablet, etc. are supported.
  • Figure 1 is a schematic view of an input device in the form of a keyboard configured to work both with a host device and a further device, according to a preferred embodiment.
  • Figure 2 is a plan view of the keyboard shown in Figure 1 , in isolation from the host device and further device.
  • Figure 3 is a functional diagram of circuitry within the keyboard of Figure 1 for maintaining simultaneously connections to both the host device and further device, according to a first embodiment.
  • Figure 4 is a functional diagram of circuitry within the keyboard of Figure 1 for maintaining simultaneously connections to both the host device and two other devices via two wireless modules, according to a second embodiment.

  • Figure 6 is a functional diagram of circuitry within the keyboard of Figure 1 for maintaining simultaneously connections to both the host device and a single shared wireless module connected to two other devices.
  • a battery allows the keyboard to continue to function wirelessly, in the absence of a host connection or other power source, according to a fourth embodiment.
  • an input device is provided, in the form of a keyboard 10, connected via a cable 15 to a host device 20, such as a laptop computer 20.
  • a host device 20 such as a laptop computer 20.
  • Other input devices are contemplated, such as mice, trackpads, etc.
  • other host devices are contemplated, such as desktop or notebook computers.
  • any conventional wired connection 15 may be used (e.g. USB).
  • the keyboard 10 controls the host device 20 via the wired connection in a conventional manner.
  • the keyboard 10 includes a pad 25 disposed over the cursor keys, for receiving a further device 30, such as a smartphone, tablet or other device.
  • the pad 25 has a slightly concave surface to accommodate various sizes and shapes of device 30.
  • a wired module 33 and a wireless module 35 are provided for controlling operation of host 20 and device 30, respectively, via keyboard 10.
  • a wired module 33 and a wireless module 35 are provided for controlling operation of host 20 and device 30, respectively, via keyboard 10.
  • the modules 33 and 35 are disposed within the keyboard 10, although a person of skill in the art will understand that the modules may be located externally of the keyboard.
  • the cable 15 provides constant power to keyboard 10 and the wired and wireless modules 33 and 35, such that there is no need for a dedicated power supply for the wireless module 35.
  • a switch 40 is disposed at any suitable location, such as above the F11 key of the keyboard 10, for switching operation of the keyboard between the wired host device 20 and the further device 30.
  • the switch 40 is an illuminated button wherein the state of illumination indicates whether the wired or wireless connection is active. When the connection is switched, user input from the keyboard 10 is redirected to the selected connection, allowing a single keyboard to control both devices 20 and 30 independently.
  • the key layout mappings for the wired and wireless connections may be different to resolve these conflicts.
  • the Windows key on an iPhone is equivalent to the Ctrl key on a PC, when performing keyboard shortcuts, such as Copy and Paste.

  • FIG. 5 The embodiment of Figure 5 is similar to that of Figure 4, except that the wireless module 35 is shared between devices 30 and 30'. In this embodiment, a time lag is experienced when switching between wireless devices 30 and 30', although switching between wireless module 35 and wired module 33 is instantaneous.
  • FIG. 6 The embodiment of Figure 6 is similar to the embodiments of Figures 3 and 5, except that a battery 45 is included for powering the wireless module 35 so that it can function on its own, when no wired connection is present.
  • a mouse or trackpad may be similarly switched between multiple devices.

Abstract

L'invention porte sur un dispositif d'entrée, tel qu'un clavier câblé, qui est configuré pour fonctionner à la fois avec un ordinateur et un second dispositif, tel qu'un téléphone intelligent ou une tablette. Le clavier intègre de préférence un module sans fil dans un clavier câblé, permettant ainsi au clavier de maintenir les deux connexions simultanément, de telle sorte qu'une commutation entre elles est instantanée. Ceci est rendu possible par le fait que la connexion câblée fournit de l'énergie constante au module sans fil, ainsi, il n'a jamais besoin de se déconnecter ou d'entrer en mode veille pour économiser de l'énergie. Grâce à une connexion de téléphone sans fil, de nombreux modèles différents de téléphone intelligent ou des tablettes plus grandes sont pris en charge.
