DETAILED DESCRIPTION
With reference to the figures, a remote control 10 is provided which incorporates an illumination device, such as one or more lamps, LEDs, or the like, which illumination device is operable to change the appearance of the remote control. The appearance of the remote control may be changed by causing the illumination device to change colors in which the remote control, or portions thereof, are illuminated, by causing the illumination device to change the intensity or brightness in which the remote control, or portions thereof, are illuminated, or the like. In particular, the appearance of the remote control device is changed through use of the illumination device to reflect the status of a timing operation and/or the status of an appliance temperature related operation, e.g., an oven heating to a set temperature.
The remote control is constructed so as to have the ability to operate, monitor, and multi-task from anywhere in the home environment. To this end, the remote control includes, as described for example in U.S. Pat. No. 7,143,214, operating circuitry powered directly by a battery and/or indirectly from another electrical source (e.g., by way of the battery recharging contacts which mate with a battery recharging contacts of a base station as shown in FIGS. 5a and 7a). As is conventional, the operating circuitry preferably includes a memory (storing instructions and a library of appliance command codes), a processor 101 (for executing the instructions and controlling components, for measuring time intervals, etc.), a user interface (such as a liquid crystal display with a touch panel overlay, keys, and/or the like), an infrared (and/or RF) transmitter circuit, an infrared (and/or RF) receiver circuit 160, and a speaker or buzzer 102. In addition, the operating circuitry includes the illumination device which, under control of the processor, is functional to illuminate all or part of the remote control to reflect the status of a timing operation (as measured locally by the remote control) and/or the status of an appliance temperature related operation (as reported to the remote control by the appliance via the two-way communication link or as timed by the remote control).
As illustrated in the figures, the base 12 (or other part(s)) of the remote control 10 may be constructed from a translucent or transparent material and thus be illuminated, in whole or in part, by the illumination device. The illumination device may also, or in the alternative, function to illuminate, in whole or in part, the user interface 14 of the remote control 10. Still further, the illumination device may also, or in the alternative, function to illuminate, in whole or in part, the top 16 of the remote control 10 or any other remote control surface.
In certain embodiments, the remote control 10 is a dedicated remote control and is adapted to remotely control operations of a single appliance. For example, FIGS. 1 and 4a illustrate a dedicated remote control having a user interface 14 appropriate for the single device to be controlled, e.g., a remote control dedicated to controlling stove functions such as start, pause, repeat, temperature control, clock, burners, clock timer with countdown/alarm, etc. In certain other embodiment, the remote control can be used to operate multiple appliances, i.e., function as a universal remote control. For example, FIGS. 2a, 2b, and 4b illustrate a universal remote control having a user interface 14 appropriate for each of multiple devices to be controlled such as a dryer, washer, oven, broiler, microwave oven, etc. In either case, the user interface 14 of the remote control may include one or more buttons, a touch screen, dials/knobs/track ball, a display, etc. for receiving user inputting and for presenting status, time display, prompts or alerts, etc. While the remote control 10 may include a speaker for alerts/alarms, more advanced sound capabilities can include a more robust speaker system for sound output such as playing of mp3s or digital music as well as for providing sound input/output to provide 2-way intercom “walkie-talkie” functionality, voice-activation of operations, and/or VOIP for remote communications such as use for servicing of appliances using remote diagnostics.
As also illustrated, for example in FIGS. 5b and 7b, the bottom 12 of the remote control 10 may be weighted and/or shaped to maintain the user interface of the remote control 10 in a viewable position, i.e., disposed in a non-horizontal position or otherwise angled towards the viewer, when the remote control 10 is placed upon a surface. The remote control 10 may also be provided with a means 20 for allowing the remote control 10 to be easily carried, such as a hole, hook, or the like formed in the remote control formed in the remote control body to thereby allow the remote control 10 to be carried by a belt or the like as illustrated in FIG. 6.
As noted, the design of the remote control 10 include the use of light to show status of timing and/or temperature operations. For example, as illustrated in FIG. 3, the illumination device, which may be multiple colored LEDs or a multi-colored LED, can cause part or the entirety of the remote control 10 to change color to indicate how much time is left in a timing operation. To this end, the remote control 10 is provided with an ability to set a time to be measured, for example by means of buttons on the user interface 14, by turning an egg-timer like dial 22, or the like. In this manner, as an example, the remote control 10 can be un-illuminated (e.g., black) when not timing and be caused to glow a green color at the start of a timed operation and conclude with a red color when the timed operation is completed while transitioning through other colors such as yellow. Similarly, by receiving messages from an appliance, the remote control 10 can be un-illuminated (e.g., black) when an appliance is not warming and be caused to glow a green color at the start of an appliance temperature setting operation and conclude with a red color when the appliance temperature setting operation is completed while transitioning through other colors such as yellow.
While the foregoing describes various embodiments of the invention in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. For example, rather than change colors to indicate changing status of time or temperature operations, the illumination device can be used to illuminate the remote control, or parts thereof, with ever increasing or decreasing intensity/brightness to this same end. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the appended claims and any equivalents thereof.
