Abstract

A portable device comprising a body, at least one wall of the body being of a translucent material and having an outer surface, an inner surface and an outer peripheral edge surface. The outer surface is coated with a first non-translucent material, there being a plurality of outer openings in the first non-translucent material to form a plurality of control indications. The inner surface is coated with a second non-translucent material, there being at least one inner opening in the second non-translucent material for at least one light source. The first non-translucent coating and the second non-translucent coating cause internal reflection within the at least one wall except for the outer openings and the outer peripheral edge through which light from the at least one light source is able to pass.

Claims

1. A portable device comprising:

(a) a body;

(b) at least one wall of the body being of a translucent material and having an outer surface, an inner surface and an outer peripheral edge surface;

(c) the outer surface being coated with a first non-translucent material, there being a plurality of outer openings in the first non-translucent material to form a plurality of control indications;

(d) the inner surface being coated with a second non-translucent material, there being at least one inner opening in the second non-translucent material aligned with at least one light source;

(e) the first non-translucent coating and the second non-translucent coating causing internal reflection within the at least one wall except for the outer openings, and the outer peripheral edge through which light from the at least one light source is able to pass.

2. A portable device as claimed in claim 1, further comprising a power controller for controlling power to the at least one light source, the control being at least one selected from the group consisting of:

(a) increasing power from off to full power when the portable device is activated;

(b) decreasing power from full power to off when the portable device is deactivated; and

(c) cyclically increasing power from off to full power to off in a repeated cycle when the portable device is connected to an external source of power.

3. A portable device as claimed in claim 2, wherein the increase and decrease in power are both steady and over a predetermined time, the predetermined time being selected from the group consisting of:

in the range 0.5 to 5 seconds, in the range 1 to 3 seconds, and 2.5 seconds.

4. A portable device as claimed in claim 2, wherein the cycle of (c) is to simulate a naturally-occurring cyclic pattern in at least one of:

amplitude, and period.

5. A portable device as claimed in claim 4, wherein the cyclic pattern is human and is selected from the group consisting of:

heartbeat, and breathing.

6. A portable device as claimed in claim 2, further comprising an illuminated display screen, the power controller also controlling power for the illumination of the display screen in the same manner as the at least one light source.

7. A portable device as claimed in claim 6, wherein the at least one wall is a top of the body, the display screen being located beneath an opening in the first non-translucent coating.

8. A portable device as claimed in claim 1, wherein the outer peripheral edges have a groove, at least a part of the groove not being coated with the first non-translucent coating.

9. A portable device as claimed in claim 1, wherein each of the plurality control indications are for one of a plurality control zones and are an indication of a function of the control zone;

the plurality of light sources not being aligned with the plurality of control indications.

10. A portable device comprising:

(a) a source of power;

(b) a power controller;

(c) a microprocessor;

(d) a memory;

(e) at least one light source for illuminating at least one of a plurality of control indications and an outer peripheral groove;

(f) the power controller being for controlling power to the at least one light source;

the control being at least one selected from the group consisting of;

(g) increasing power from off to full power when the portable device is activated;

(h) decreasing power from full power to off when the portable device is deactivated; and

(i) cyclically increasing power from off to full power to off in a repeated cycle when the portable device is connected to an external source of power.

11. A portable device as claimed in claim 10, wherein the increase and decrease in power are both steady and over a predetermined time, the predetermined time being selected from the group consisting of:

in the range 0.5 to 5 seconds, in the range 1 to 3 seconds, and 2.5 seconds.

12. A portable device as claimed in claim 10 further comprising:

(a) a body;

(b) at least one wall of the body being of a translucent material and having an outer surface, an inner surface and the outer peripheral groove;

(c) the outer surface being coated with a first non-translucent material, there being a plurality of outer openings in the first non-translucent material to form a plurality of control indications;

(d) the inner surface being coated with a second non-translucent material, there being at least one inner opening in the second non-translucent material aligned with at least one light source;

(e) the first non-translucent coating and the second non-translucent coating causing internal reflection within the at least one wall except for the outer openings and the outer peripheral groove through which light from the at least one light source is able to pass.

13. A portable device as claimed in claim 12, wherein the at least one wall is a top of the body, a display screen being located beneath an opening in first non-translucent coating;

the power controller also controlling power for the illumination of the display screen in the same manner as the at least one light source.

14. A portable device as claimed in claim 10, wherein each of the plurality control indications are for one of a plurality control zones, each of the plurality of control zones being an indication of a function of the control zone;

the plurality of light sources not being aligned with the plurality of control indications.

15. A portable device as claimed in claim 10, wherein the outer peripheral groove has a vertical portion and a horizontal portion, at least one of the vertical portion and the horizontal portion not being coated with the first non-translucent coating.

16. A method for controlling illumination of a portable device, the method comprising using a power controller of the portable device to control power supplied to at least one light source for providing the illumination, the control being at least one selected from the group consisting of:

(a) increasing power from off to full power when the portable device is activated;

(b) decreasing power from full power to off when the portable device is deactivated; and

(c) cyclically increasing power from off to full power to off in a repeated cycle when the portable device is connected to an external source of power.
