Amidst Galaxy Note 7 Recall, USPTO Publishes Samsung Patent Application for HMD with a Heat Radiator

As reported by various news outlets today, Samsung announced an unprecedented recall of the Galaxy Note 7 just weeks after launching the smartphone due to the phone’s battery, with some scattered reports that “the cell can explode while charging.”

In a bit of irony, yesterday, the USPTO published Samsung’s patent application for a HMD having “a heat radiator” for removing heat from the space between the display and the optical assembly while a smartphone is actively engaged.  The device in the application appears to be a version of the Gear VR, with which the Galaxy Note 7 was designed to operate.

As seen in FIG. 6 (below) of Samsung’s application, the HMD includes a heat radiator 400 on a side surface of the frame 202.  The heat radiator 400 includes a fan 410 with a blade, or a piezo cooler, and also includes a fan duct 420 and a fan cover member 430.  The fan 410 and the fan duct 420 is installed in the frame 202 in a mounting opening unit 260.

As shown in FIG. 7 (below), the heat radiator 400  dissipates the heat from the smartphone 300 by bringing external air into the frame 202.  Heat is transferred to the air introduced into the frame 202 through the heat radiator 400, and then the air is discharged through an outlet on the bottom surface of the frame 202, thus making it more comfortable for the user of the device 200.

Samsung’s application also discusses using a heat diffusion member that can be installed to more efficiently transfer heat from the smartphone to the air in the frame 202. The heat diffusion member may be a graphite sheet, a heat transfer member containing carbon such as graphene, a metal member such as a copper sheet, or a heat transfer member such as a heat pipe or heat sink.  The application makes no mention of fire suppression technology.

According to public records, Samsung’s patent application claims priority to a Korean patent application that was originally filed in February 2015.

Apple Receives Patent for Head-Mounted Display for Use with Smartphones

Apple has been in the news a lot lately  — from the $14.5 billion EU tax fine to the anticipated announcement of the iPhone 7 just a few days away.

However, Apple has been conspicuously silent about its plans with regard to virtual and augmented reality. Although Apple has not made any formal announcements (apart from recent statements by Tim Cook, Apple’s CEO, regarding VR and AR), it’s patent filings may provide a hint about the direction they are going.

On Tuesday, the USPTO issued a new patent to Apple (USP No. 9,429,579), entitled “Head-Mounted Display Apparatus for Retaining a Portable Electronic Device with Display.” This marks the seventh U.S. patent that Apple has received relating to HMDs. (Samsung has fourteen U.S. patents relating to HMDs, with five of them being design patents.) Although recently issued, the ‘579 patent is a member in a family of patents, whose parent was filed in September 2008.  In other words, Apple has been toying with the idea of an HMD for at least the last eight years.

Claim 1 of the ‘579  patent recites:

A head-mounted device that is worn on a user’s head and configured to integrate with a cellular telephone that is removable, the head-mounted device comprising:

a frame that is configured to physically receive and carry the cellular telephone, wherein the frame places a display screen of the cellular telephone in front of the user’s eyes; and

an optical subassembly configured to receive at least one image frame from the display screen of the cellular telephone, wherein the optical subassembly is interposed between the display screen and the user’s eyes.

As described in the specification, the optical subassembly (shown below at 604) may include “lenses, light guides, light sources, mirrors, diffusers, and the like.” Specifically, optical sub assemblies may include “aspherical and diffractive optical arrangements.”  In addition, the optical subassembly may also include “one or more optical modules that may be operative to adjust or modify the displayed media based on any suitable criteria.” For example, the “optical modules” may offset left and right images so that the user is given the illusion of viewing media in three dimensions.

As we’ve said before, a company’s patent filings are certainly no guarantee that a commercial product will ever be released.  However, based on recent rumors surrounding Apple’s acquisitions, hirings and iPhone 7 technology, it is a good bet that Apple has something in the works.
