Apple's Patent Background

Conventionally, a portable electronic device has a housing that encases various electrical components of the portable electronic device. Often, the portable electronic device has one or more indicator lights. For example, the housing can include a small hole through which light can be expelled when an indicator light is to be provided. The indicator lights can be used for various purposes, such as for a status indication or an alert to be provided to a user of the portable electronic device. Examples of common indicator lights include a battery charging indicator light, a power-on indicator light, etc. Unfortunately, however, the holes in the housing for the indicator lights are visible and cosmetically unappealing when the indicator lights are not use.

Apple Invents Method of Camouflaging Apertures in iDevices and Beyond

Techniques and apparatus for providing one or more holes in a housing for an electronic device. The one or more holes in the housing can be used to facilitate visual indicators. A light source can be controlled to provide light into a hole and thus emit light from the hole. When the light source is not providing light to the hole, the hole can be visually disguised (e.g., camouflaged) so it blends with the surrounding portions of the housing. The electronic device can, for example, be a small electronic device, such as a portable or handheld electronic device.

Embodiments of the invention can be implemented in numerous ways, including as a method, system, device, or apparatus. Several embodiments of the invention are discussed below.

As an electronic device, one embodiment can, for example, include at least: a housing having an outer exposed surface with at least one hole extending therethrough, the housing at least partially covering an inner region; a light source provided within the inner region and proximate to the at least one hole; a light transmissive filler provided in the hole; and light reflective material selectively provided in or on the light transmissive filler.

As a method for camouflaging an indicator hole in an outer housing for an electronic device, one embodiment can, for example, include at least: filling at least a portion of the indicator hole with a transparent material to seal the indicator hole; and selectively providing light reflective material in or on the transparent material provided in the indicator hole.

As a consumer electronic device, one embodiment can, for example, include at least: a housing having an outer exposed surface with at least one hole extending therethrough, the housing at least partially covering an inner region; a light source provided within the inner region and proximate to the at least one hole; a controller provided within the inner region and operatively coupled to the light source to control when the light source emits light; a polymer filler provided in the hole; and ink selectively provided in or on the polymer filler.

Apple's patent FIG. 2B noted below is a cross-sectional diagram of a portion of an iPhone (electronic device #200) in an illuminated state in which light produced by the light source #210 is projected through the hole. In patent FIG. 2C an iPhone illustrates a non-illuminated state in which a portion of incoming external ambient light is reflected by the light reflective material #218 to produce reflected ambient light #242. The reflected ambient light can provide a visual impression that the hole or aperture isn't present. In other words, when the light source is inactive, the hole is disguised whereby the user does not visually perceive the existence of the hole.

As a result, the light reflective material allows the hole in the housing member to be disguised or camouflaged while the light indication is not being provided. Apple notes that the light reflective material comprises a plurality of micro dots of ink.

Apple's patent FIG. 3 illustrated below is a housing indication process.

Apple notes that the reflective elements can disguise or camouflage the hole in a device as shown in patent FIG. 7 below. The number, size, shape and spacing of the reflective elements can vary widely with implementation. Through the use of inks in one or more colors and in one or more layers, there is a great deal of flexibility for the visual appearance of the hole to appear any color. Hence, the visual appearance of the hole #704 (when the light indication is inactive) can take on any desired color.

Apple lastly notes that the techniques and apparatus described in their invention may be applied to housings used by any of a variety of electronic devices including but not limited handheld electronic devices, portable electronic devices and substantially stationary electronic devices. Examples of these include any known consumer electronic device that includes a display. By way of example, and not by way of limitation, the electronic device may correspond to media players, mobile phones (e.g., cellular phones, smart phones), PDAs, remote controls, netbooks, notebooks, tablet PCs, gaming controllers, monitors, all in one computers like the iMac and the like.

Apple's patent application which was published today by the US Patent Office was originally filed on June 19, 2013. Apple credits Kroghahl, Ng and Rimple as the inventors.
