Foreign media reported that the U.S. Patent and Trademark Office recently granted Apple another patent for a head-mounted display system, which is different from their recently filed patent applications. Apple's VR helmet patent application began in 2007, many years before Samsung's Gear VR or Google's new Daydream VR helmet. Although over the years, it has been frustrating to see Apple's competitors launching products that Apple has already registered for patents, Apple usually carefully considered these ideas before launching the product.

For example, Apple had studied on modern digital pens for many years before launching Apple Pencil, but once they launched the product, they provided users with higher precision and almost no lags or delays, defeating various stylus on the market. Competitors.
In the recently-licensed patent, the focus is on a touch sensor that extends along the spectacle frame, which the user can use as a slider controller. One of the controls of the touch sensor is the volume of the speaker in the helmet. Apple's patents never talk directly about AR or VR, but instead are three-dimensional views of content.
Apple also describes an auxiliary control member that the user can rotate to adjust the distance between the system and the user's eyes. This control member is a knob.
More interestingly, Apple stated in the patent right of Patent No. 8 that "The system includes: a head-mounted carrier; a display supported by a head-mounted carrier, wherein the display generates a first frame of image for the user's first eye. And generating a second frame image for the user's second eye; and a touch sensor on the head-mounted carrier, the system can receive an optometry prescription from the user, and modify the first frame and the second frame image according to the optometric prescription And the optometry prescription can be selected from the glasses prescription and contact lens prescription.
Previously, we reported on multiple VR/AR technology patents applied for or obtained by Apple. However, Apple has not launched its own VR/AR products. Even during this year's new mobile phone conference, no information was revealed. However, according to Cook, he is still more optimistic about the prospects of AR technology. Perhaps Apple will focus on the AR field.
Peel Mask PCB
Peel able masks are used in order to protect selected solder holes against plugging during mass soldering or to protect carbon elements and gold plated contacts during mass soldering. Peel able masks are screen printed.
Requirements
• The peelable mask must adhere sufficiently well to the PCB so that it does not peel off when handled correctly.
• It must be able to endure a two to three time soldering process without peeling off, but must remain detachable.
•After soldering of the PCB, the peelable mask must be able to be detached – preferably in one piece. In case of metallized holes, no mask
residue must be left in the drill holes or on the surface of the PCB. In the case of non-metallized drill holes, however a certain amount of residue
can remain.
• The peelable mask must be able to resist conventional solvents such as chlorinated and fluorinated hydrocarbons, isopropanol, conventional
fluxes and similar.
• Particular requirements: The roughness U of the edge of the mask can be 0,5 mm from the tip to the base (left figure
below).
