A lighting system consists of a main body , which has an interior chamber , as well as a lighting apparatus attached to the main body. The lighting assembly includes at the very least one source of light. The light assembly further comprises a fan configured to generate an airflow, and an airflow circuit designed to direct the airflow out of the body that is the primary part of the lighting unit. The light system is also equipped with a tilt detection unit configured to detect the tilt angle in the lighting fixture and to create a control signal that will trigger a speed of airflow generated by the fan to vary based at least on an observed change in the tilt angle of the lighting fixture.

A surgical light is usually placed over a surgical site in operating rooms at hospitals. The surgical light contains at least one light source that are equipped to project a narrow beam of light onto the target area of a surgical procedure.

Furthermore, a supply-air array is situated within a ceiling directly above the surgical light as well as the area of the surgical site that is targeted for. The supply air array is comprised of vents through which air filtered is supplied and directed toward the surgicalsite. Filters are installed inside the vents to remove the air that passes through them. Sidewall vents are used to redirect air that is polluted from the room’s perimeter to an air filtering system that is located upstream of the supply array. Air filtration supplies filtered air to the room via the supply air array, which has unidirectional, downward flow.

Since the surgical light could be positioned just over the surgical zone of the target, the light may block airflow generated by the supply air array and create the appearance of a low-pressure zone beneath the light used for surgery. The cause of air turbulence is the pressure drop. Due to turbulent airflow, various contaminants generated through the surgical process could be circulating within the surgical environment. If there is no unidirectional flow that is filtered, particulate and bacterial contaminants could be carried by surgical staff. Furthermore biological fluids, blood and bone fragments can be pushed upwards toward the surgical lighthead, which is sterilized and cleaned in between operations.

A method and system that allows continuous low-turbulence, low-turbulence airflow when using the light of a surgical procedure is required. The need is for a method and system to reduce the risk of contaminants being dispersed over the area of surgery.

Certain embodiments of this disclosure provide a light system that includes an main body that defines an internal chamber, as well as an assembly for lighting which is attached to the main body, wherein the lighting assembly comprises at least one light unitconfigured to produce light. The light system further includes a fan configured to generate an airflow as well as an airflow circuit that is configured to direct the flow of air from the main body of the lighting assembly. A tilt detection unit is included in the lighting system. It determines the tilt angle and generates a control signal that causes the speed of the fan to vary in accordance with the tilt angle.

The present disclosure describes a method to control the airflow of lighting assembly. It involves determining the tilt angle of the lighting device and controlling the flow of air out of the main body via an airflow circuit. The control signal is created to alter the speed of fan airflow based on any detected tilt angle change.

Certain embodiments provide computer storage media with computer-executable instructions for controlling the flow of air through a lighting system. These instructions, when executed by a CPU will cause the processor to produce a signal that causes the rate of airflow through the fan to alter based on the tilt angle detected by the lighting unit.

What is a patent?

Granted by the government to safeguard an invention, patents grant the inventor with exclusive rights to create, use and sell the invention? Society benefits when a new technology is brought to the market. The benefits can be realized immediately when people can accomplish feats previously unattainable as well as indirectly through the opportunities for economic growth which innovation can bring (business expansion, jobs).

Many drug companies and researchers at universities seek protection under patents to protect their research and development. A patent can cover a physical or abstract product or process or composition or method of making materials new to the field. Patent protection has to be granted to any invention that is valuable, novel, and not already known by others in the same area.

Patents give inventors a chance to be recognized for commercially viable inventions. They act as a motivator for inventors to come up with new ideas. Small businesses and inventors are sure that they will earn a return on their investment in technology development via patents. They can make a living by their work.

Businesses with the ability to:

Make sure you protect your unique products and services.

Increase the value, visibility, and attractiveness of your products on the market

Your business and your products should be distinguished from the rest;

Access technical and business knowledge and information;

Avoid the danger of accidentally using third-party proprietary content, or losing your valuable information, innovative outputs, or another creative output.

Patents transform inventors’ knowledge into a commercially tradeable asset which opens new opportunities for job creation and business growth through licensing or joint ventures.

Investors who are involved in the development and commercialization of technology will appreciate small companies with patent protection more appealing.

Patenting can lead to innovations and new ideas. This information can promote innovation and may qualify for patent protection.

Patents can be used as a deterrent to untrustworthy third parties profiting from the efforts of an invention.

Revenues from patent-protected technology that are commercially successful could be used to fund research and development (R&D), which will improve the chances of developing better technology in the future.

It is possible to use the intellectual property rights of your company to convince investors and lenders that your product is a viable commercial potential. Sometimes, a single patent could open the door to multiple financing opportunities. Patents as well as other IP assets can be used as collateral or security to finance debt. Investors can also see your patent assets to boost the value of your company. Forbes and other sources have pointed out that each patent can increase anywhere from $500,000 to million dollars to your company’s valuation.

Startups require a carefully-crafted business plan that leverages the IP to show that your product or service is unique, superior, or innovative. Investors will also be impressed if you show that your IP rights are secure or in the process of becoming secure, and that they align with your business strategy.

It is essential to keep an invention secret before applying for patent protection. Public disclosure of an invention before it is filed can often destroy its novelty and render it unpatentable. Thus, prior filing disclosures (e.g., for test-marketing, investors, or other business partners) should only be filed upon signing a confidentiality contract.

There are many types of patents. Understanding them is crucial for protecting your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Patents for utility are the best option and protect the owner against copycats and other competitors. In most cases they are granted for modifications or improvements to existing inventions. Utility patents can also be used to improve or modify existing inventions. For instance, a procedure patent covers acts or methods for performing a specific act, whereas chemical compositions will comprise an assortment of components.

How long will a patent last? Utility patents last 20 years from the initial date of filing, however their expirations may be extended because of delays in the patent office, for example.

Interested in finding more similar patents? These are the steps to follow:

1. Create a list of terms for your invention, based on its purpose composition, use, or purpose.

Write down a short and precise description of the invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Instead, think about synonyms for the terms you chose initially. Also, keep track of significant technical terms, as well as key words.

Use the questions below to help you identify key words or concepts.

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Invention is a method to make something or carry out some function? Or is it a product or process?
  • What is the structure of the invention? What is the physical structure of the invention?
  • What is the purpose of this invention?
  • What are the technical terms and terms that describe the nature of an invention? To assist you in finding the correct terms, consult an online dictionary of technical terms.

2. These terms allow you to look up relevant Cooperative Patent Classifications on the Classification Search Tool. To determine the most suitable classification to your invention, scan the resulting classification’s class Schemes (class schedules). Consider substituting the words you use to describe your invention if you don’t get any results from the Classification Text Search with synonyms like the ones you used in step 1.

3. Examine 3. Check the CPC Classification Definition for confirmation of the CPC classification you found. The hyperlink to a CPC classification definition is given when the classification you have selected has a blue box that includes “D” on the left. CPC classification definitions can aid you in determining the classification’s scope so that you can choose the one that is most appropriate. Additionally, these definitions can include research tips and other suggestions that could be helpful in further investigation.

4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. You can review and select the relevant patent publications making a focus on 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 sure to read the claims and specification. Consult the applicant and patent examiner to obtain additional patents.

6. Search for patent applications that have been published using the CPC classification you chose in Step 3 of the Applications Full-Text and Image Database. You may also employ the same search strategy that you used in step 4 to limit your search results to the most relevant patent applications by reviewing the abstracts as well as the drawings for every page. Then, you must carefully review the patent applications that have been published and pay particular attention to the claims and additional drawings.

7. You can look up additional US patent publications using keywords searching in AppFT or PatFT databases, as well as search for patents classified as that are not issued by the United States in the following table. You can also utilize web search engines to find non-patent documents that describe inventions in the literature. Here are some 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:
  • 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.
