Search Patent for Artificial Reality content presented through a mirror
A projector screen is a screen that shows projected images. It may be made from paints, fabric or other materials with granular structure. In certain ways the more granular of the screen, the greater the amount and evenly the screen will scatter light. The Lambertian diffuser is a screen that distributes light evenly. It is a kind of optics. A Lambertian diffuser may be able to evenly distribute light incident on it over a distance of 2.pi. solid angle. This property could be beneficial for projector screens that can be used in home theaters and movie theaters. However, conventionalprojector screens are not necessarily switchable between a transparent state and a reflecting state. These projector screens are utilized in large-scale environments like a home or construction site. They are not typically used in the context of wearable devices.
In greater detail below, the instant disclosure describes switchesable electroactive devices which may be utilized in head-mounted displays (HMDs). One embodiment of a display device comprises an electroactive device situated so that it’s not directly in contact with the eyes of the user when the device is worn. Further the electroactive device can comprise (1) an electroactive element including an electroactive element that comprises apolymer material defining nanovoids as well as (2) electrodes that are electrically connected to the electroactive element and equipped to apply an electrical field to the electroactive element wherein the electroactive element is compressible from an uncompressed stateto one that is compressed by the application of the electric field in such a way as to reduce the size of nanovoids and increase the number of nanovoids that are present in the compressed state. Moreover, an emissive device placed to reflect images onto the surface of the electroactive device in front of the eye of the user. An ultra-short throw projector may be used as an emissive device.
In certain instances the electroactive device might appear substantially opaque in its uncompressed state. The electroactive element could be transparent when compressed. The initial average size of the thenanovoids in the uncompressed electroactive element is approximately the size of the wavelength of light incident. The nanovoids in the electroactive element uncompressed might be as small as one order of the incident light. Additionally, in thecompressed state of the electroactive element, the nanovoids possess a second size average that is significantly smaller than the incident light. The nanovoids of the electroactive element compressed could have an additional average size which is significantly smaller than the wavelength of the incident light.
In certain instances, the display system may also include an eyepiece that is positioned between the eye of the user and the electroactive device. When the eyepiece is in an active state an eyepiece, it can be used to move the focal point of the user’s eye from a fixed plane on the electroactive device. The active state of the eyepiece may be utilized as a virtual reality application. Additionally, the inactive condition of the eyepiece could be used in an AR application or mixed reality application.
In one example eyepieces, there is a proximate eyepiece and the display device could also include a distal eyepiece positioned near an electroactive device, which is in opposition to the eyepiece that is proximate. One instance is that the amount of light scattering incidentally by the electroactive element can be determined at least in part based by one of the following factors: the average size or density of the nanovoids.
In a different embodiment an alternative embodiment, a display device is described. The display system may include an electroactive device that includes an electroactive element and electrodes that are electrically connected to the electroactive element. The display may include a waveguide LCD that is situated between the person wearing the device and the electroactive element. This LCD is able to transmit images to the eyes of the user while the device is in use. The waveguide display can be programmed to function with a light source in some instances. The light source may comprise at least one of the following examples: a micro-light emitting, light emitting, or laser.
The method described is also similar. This may involve applying an electric field to an electrode of an electroactive device to reduce the size of the element. Electroactive devices includes a polymer material that defines nanovoids. The device may be set in a position that is away from user’s eyes. The method can also comprise emitting light from an emissive device positioned such that at least a portion of the image light is incident on the surface of the electroactive device in the direction of the user’s eyes. In certain embodiments, the method may further include reducing the strength of the electrical field applied to the electroactive element in an electroactive device in order to extend the electroactive element from a compressed state to an uncompressed state so that the size of the nanovoids is increased and the quantity of nanovoids is decreased within the electroactive element.
You can combine features from one or more of these embodiments in accordance to the principles set forth herein. The various embodiments, features, and benefits will be thoroughly understood after reading the detailed description in conjunction with the accompanying drawings and claims.

What is a patent?
Patents are granted by the government to safeguard the invention. It gives the inventor the sole rights to develop, use and sell the idea. Society is benefited when new technology is brought to the market. The benefits can be in the direct sense, since it allows individuals to achieve previously unattainable things. Or indirectly through the economic opportunities (business growth and employment) which the invention provides.
Patent protection is demanded by a variety of pharmaceutical companies and university researchers to protect their research and development. Patents can be granted to an abstract or physical product or process, or an approach or composition of materials that are new to the area. Patent protection is granted to an invention that is useful unique, innovative, and not previously known to others in the same field.
Patents are awarded to inventors who have commercially successful inventions. They serve as a motivator for inventors to create. Small companies and inventors can rest assured that they will get an income from the investment they make in technology development through patents. It means that they can make a living by their work.

How to Search for Patents
The first step in getting your patent is to do an internet search for patents. You can do a google patent search or do a USPTO search. Patent-pending is the name used to describe the product that has been covered by the patent application. It is possible to search the public pair to locate the patent application. When the patent office has endorsed the application, you will be able to perform a patent search to locate the patent that was issued and your product will now be patented. Alongside the USPTO search engine, you can use other search engines, such as espacenet as described below. For assistance, consult an attorney for patents. In the US Patents are granted by the US patent and trademark office or by the United States patent and trademark office, which also examines trademark applications.
Are you interested in finding similar patents? These are the steps to follow:
1. Brainstorm terms to describe your invention, based on its purpose or composition.
Write down a short, but precise description of the invention. Don’t use generic terms like “device”, “process” and “system”. Consider synonyms for the terms you initially chose. Next, note important technical terms and keywords.
Use the questions below to help you identify the keywords or concepts.
- What is the purpose of the invention? Is it a utilitarian device or an ornamental design?
- Does the invention consist of a method of creating something or carrying out a function? Is it a product or procedure?
- What is the structure of the invention? What is the physical structure of the invention?
- What’s the point of the invention?
- What are technical terms and phrases that define the nature of an invention? A technical dictionary will help you identify the correct phrases.
2. These terms allow you to search for pertinent Cooperative Patent Classifications at Classification Search Tool. To determine the most suitable classification to your invention, look through the class scheme of the classification (class schedules). If you don’t get any results from the Classification Text Search, you may want to consider replacing the words that describe your invention with synonyms.
3. Review the CPC Classification Definition to determine the relevancy of the CPC classification that you have discovered. The link to the CPC classification definition will be provided when the classification you have selected has a blue box that includes “D” on the left. CPC classification definitions can help identify the specific classification’s scope which is why you can be certain to choose the one that is appropriate. These definitions may also include search tips or other suggestions that could be helpful for further research.
4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. You can search and find the most relevant patent publications focusing first on the abstract and drawings representative of.
5. Utilize this list of most relevant patent publications to look at each one in depth for any similarity to your invention. Be aware of the claims and specification. You may find additional patents by referring to the patent examiner as well as the applicant.
6. You can retrieve published patent applications that match the CPC classification you picked in Step 3. It is possible to use the same strategy of searching as Step 4, narrowing your search results to the most relevant patent application by looking at the abstract and representative drawings that appear on each page. Then, you must carefully review the patent applications published with particular attention paid to the claims as well as additional drawings.
7. Find additional US patent publications by keyword searches in the PatFT and AppFT databases, searching for classification of non-U.S. patents as per below, and searching non-patent publications of inventions with web search engines. Here are a few examples:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
