Ambarella International LP (Santa Clara, CA)

The stereo camera and the processor are two components of an apparatus. The stereo camera can include a first device for capturing and a second device in the vertical orientation. The first capture device can be set up to create the first pixel data, while the second capture device can be configured to produce the second pixels. The processor could be programmed to create the images of first and second pixels respectively, and create a vertical dispersion image. It could also create the virtual horizontal image in response to the first and second pixels. Detect objects using the virtual vertical disparity and virtual horizontal disparity images. The processor could be able to identify objects that aren’t visible in the vertical disparity images alone by analysing the virtual horizontal dispersion.

Stereo vision provides useful data for computer vision. It is possible to calculate distances between objects based on previously known information. This includes distance between stereo pair of cameras. Distance information is helpful in determining the spatial relationship between objects, and/or to determine the dimensions of objects.

Stereo cameras can also be placed in various orientations, including horizontal orientation vertical orientation, diagonal orientation. Each orientation has its advantages and disadvantages. Vertical poles are difficult to identify when viewed from a baseline. In a disparity calculation the vertical poles represent a singularity. The horizontal orientation can solve the problem, however using a horizontal baseline eliminates the benefits of the vertical baseline orientation. Multiple stereo camera pairs can be used to achieve different orientations. But, it’s costly.

It would be desirable to implement a virtual horizontal stereo camera.

This invention concerns an apparatus which includes an stereo camera and processor. A stereo camera could comprise a first capture device, and a second capture with a vertical orientation. The first capture device can be set up to generate first pixel data , and the second capture device may be set up to generate second pixels. The processor could be configured to receive both first and second pixel images and then generate a vertical dispersion image in response.

What is a patent?

A patent is issued by the government to safeguard an invention. It grants the inventor the sole right to create, use and market the invention. Society gains when new technologies are brought to the market. These benefits may be realized directly as individuals are able to accomplish previously impossible feats, or indirectly through the opportunities for economic growth that innovation offers (business expansion, jobs).

A lot of pharmaceutical companies and university researchers seek patent protection to protect their research and development. Patents are granted for products, processes, or method for making new materials. In order to be granted protection under a patent the invention must be useful or novel, as well as not readily apparent to anyone else in the same subject.

Patents give inventors a chance to be recognized for commercially viable inventions. They are an incentive to inventors to come up with new ideas. Patents allow inventors and small businesses to know that there’s the possibility that they’ll be paid back on their time, effort and investment in technological development. They could earn a decent income through their work.

Patents are a crucial part of firms and can be used to:

Protect your innovative products and services.

Improve the visibility and the value of your product’s presence on the market

Make your brand stand out from others.

Find business and technical information.

Beware of accidentally using content from third parties or losing valuable data, creative outputs or any other outputs that are creative.

Patents transform inventors’ knowledge into a commercially tradeable asset, which creates new opportunities to create jobs and boost business growth by licensing or joint ventures.

Small businesses that have patent protection are more attractive to investors in the commercialization and development of technology.

Patents can lead to innovative ideas and inventions. The information you create may be protected by patents.

Patents can be used to prevent untrustworthy third-party companies from earning through the work of inventions.

Patent-protected technology revenues that are commercially profitable can be used for financing technological research and development (R&D) that can enhance the likelihood of improved technology in the future.

You can use intellectual property ownership to convince lenders and investors that your product is a viable commercial value. One powerful patent may lead to numerous financing options. Patents as well as other IP assets can be used as collateral or as security to finance debt. Investors can also see the patents you own to boost the value of your business. Forbes and other publications have pointed out that each patent can increase the value of your company by as much as $500,000 to $1 Million.

Startups require a carefully-crafted business plan that builds on the IP to prove that your product/service is unique and superior or ingenuous. Investors will also be impressed if your IP rights are secure or are in the process of becoming secure and they endorse your business plan.

It is essential to keep an invention secret until you submit to protect it with patents. The public divulging an invention could be detrimental to its originality and make it invalid. Pre-filing disclosures, such as for investors, test marketing, or other business partners, is best done following the signing of a confidentiality agreement.

There are many kinds of patents, and understanding them is essential to protecting your invention. Utility patents cover new techniques and machines. Design patents cover ornamental designs. Patents for utility are the most effective because they shield the owner from copycats and other competitors. They are typically granted to enhance or modify existing inventions. Utility patents can also be used to enhance or alter existing inventions. For example, a procedure patent will be able to cover actions or methods of doing one specific thing, whereas chemical compositions will comprise an assortment of components.

How long does a patent last? Utility patents last 20 years from the earliest filing date, but their expiration dates can be extended due to patent office delays such as.

This will allow you to know the extent of your invention as well as prepare you for the filing of your patent application.

How to Search for Patents

The first step to get your patent is to perform a patent search. You can do a google patent search or do a USPTO search. Once the patent application is submitted, the product that is subject to the patent can be described as patent-pending. you will be able to locate the patent application on a public pair. When the patent office is satisfied with your application, you’ll be able to conduct a patent number look to find the patent issued. Your product is now patentable. Alongside the USPTO search engine, you can also utilize other search engines, such as espacenet, which is described below. A patent lawyer or attorney can assist you with the procedure. In the US, patents are issued by the US trademark and patent office, also known as the United States patent and trademark office, which is also responsible for examining trademark applications.

Interested in finding more similar patents? Here are the steps:

1. Think of terms to describe your invention, based on the purpose, composition and use.

Begin by writing down a succinct, precise description of your idea. Do not use generic terms such as “device”, “process”, and “system”. Instead, consider synonyms to the terms you initially chose. Also, keep track of significant technical terms as well as key words.

To help you find terms and keywords, you can use the questions below.

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Is invention a way to come up with something or to perform an action? Are you referring to a product?
  • What is the basis of the invention? What is the physical constitution?
  • What is the purpose of this invention?
  • What are the technical terms and terms used to describe the nature of an invention? A technical dictionary can assist you to identify the correct words.

2. Use these terms to find relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you are unable to locate the appropriate classification to describe your invention, look through the classification’s Schemas of classes (class schedules). Consider substituting the words that you’re using for describing your invention, if you don’t get any results from the Classification Text Search with synonyms similar to the words you used in the first step.

3. Examine 3. Go over the CPC Classification Definition to determine the relevancy of the CPC classification you’ve discovered. The hyperlink to the CPC classification definition will be given if the chosen classification title is a blue square with a “D” to its left. CPC classification definitions can assist you in determining the classification’s scope , so you can select the most appropriate. Furthermore they can provide research tips and other suggestions that could be useful for further research.

4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. You can search and narrow down the most relevant patent publications making a focus on abstract and representative drawings.

5. Use this selection of the most pertinent patent documents to examine each in detail for similarities to your invention. Take note of the specification and claims. Consult the applicant and patent examiner for additional patents.

6. You can find published patent applications that meet the CPC classification that you picked in Step 3. You may also employ the same strategy of searching you utilized in Step 4 to narrow down your results to the most relevant patent applications by looking over the abstracts and representative drawings for each page. Then, you must carefully review the patent applications that have been published with particular attention paid to the claims as well as additional drawings.

7. Find other US patents by keyword searches in the PatFT and AppFT databases, searching for classification of non-U.S. patents per below, and searching non-patent patent disclosures in the literature of inventions using web search engines. For example:

  • 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:
  • 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.
