Tesla's Crazy Laser Windshield Wipers Are Published by the US Patent Office

Tesla’s idea for a crazy windshield wiper that would use a laser beam to clear debris out of sight of the driver has been officially published by the United States Patent Office. Tesla filed for the patent in May 2019, and it was eventually granted in late 2021. Now, the US Patent Office has published the patent, making it publicly viewable.

Tesla has long been interested in some very crazy and revolutionary ideas for the automobile. Over the years, Tesla has seen many different designs and ideas for windshield wipers, using anything from a single-wiper system for the next-gen roadster, which uses an electromagnetic system to rid the windshield of moisture. Will use linear actuator, without wipers. When it unveiled Cybertruck in November 2019. Recent sightings of Tesla’s Cybertruck have indicated that the vehicle will have wipers, but Tesla is still revising the design.

With all the crazy ideas Tesla has thrown about for Vipers in the past, the automaker’s patent for “pulsed laser cleaning of debris accumulated on glass articles in vehicles and photovoltaic assemblies” is one of the most interesting. Originally filed in May 2019, Tesla had the idea recently published by the US Patent Office, meaning that if the office doesn’t eventually grant a patent, the public can still learn from the work and perhaps develop another system. what can be provided.

Tesla describes the patent in a now-published filing:

A cleaning system for a vehicle includes a beam optics assembly that emits a laser beam to irradiate an area on a glass article of the vehicle, debris detection circuitry that detects debris accumulated in the area. Detects, and controls the circuitry. The control circuitry calibrates a set of parameters associated with the laser beam emitted from the beam optics assembly based on the detection of field-deposited debris on the glass article, controls the exposure level of the laser beam on the accumulated debris. Is. The set of parameters associated with the laser beam, controlling the exposure level by pulsing the laser beam at a calibrated rate that limits the penetration of the laser beam to a depth that is less than the thickness of the glass article and Removes debris that accumulates in the area on the glass article using a laser beam.”

It’s not necessarily confirmed or known what Tesla’s plans might be for laser windshield wipers, but images within the patent appear to show the Model S body. Tesla may be ready to test this type of device on some of its vehicles, but the automaker has never detailed specific plans for the idea.

Tesla’s flowchart describing the process for the patent is relatively simple, and also shows the use of cleaning up debris from solar panels. In five steps, the patent describes the use of the laser cleaning assembly:

  1. Locate debris deposited on an area on an article of glass installed in the vehicle
  2. Calibrate a set of parameters associated with the laser beam emitted from the beam optics assembly, based on the detection of debris deposited on an area on the glass article
  3. Control the exposure level of the laser beam on the debris deposited on the glass article based on the calibration of a set of parameters associated with the laser beam
  4. Radiation fields associated with debris detected on articles of glass by laser beams
  5. Remove debris accumulated on the area by laser beam

It doesn’t seem to be driven by the vehicle itself. Tesla describes the capability of a manual system where the driver can control the laser via a touchscreen, joystick, or any other means to communicate with the various operating components of the cleaning mechanism.

While it sounds like a strange and potentially satirical idea, using a laser to clean windshields wouldn’t be too far out of the realm of Tesla’s ideas. After all, CEO Elon Musk has said in the past that the Roadster will fly thanks to SpaceX cold gas thrusters, Tesla has filed a patent for the Cybertruck to have solar cells on its ton for extra electric vehicle range, and plenty of others. crazy idea. However, the new laser patent, if eventually used by Tesla, would only reduce the already minimal maintenance cost, as the annual maintenance cost on EVs is extremely low.

Tesla Model Y welcomed by Kansas PD, expected to give cost savings – Elon Musk - Elon Musk

In a recent press release, the Leawood Police Department in Kansas announced that it had acquired a Tesla Model Y Long Range for its fleet. The vehicle would be used as one of the Leawood PD’s patrol cars. The Model Y has already been painted in the Leawood PD’s black and white colors. The department noted that they started looking into the idea of an all-electric patrol car last year after seeing dismal reviews of available hybrid patrol cars. Captain Kirt Yoder, the agency’s project manager, noted that Tesla Kansas had been quite helpful. “I ended up contacting about ten agencies from New York to California. Tesla-Kansas City was great. They were eager to help and answer all our questions,” he said. Apart from being a green vehicle, the Model Y is also expected to give the Leawood Police Department substantial cost savings. Over a year ago, a cost comparison already showed that the department’s Ford Explorer patrol SUV would cost about $4,500 per year to run. That was a time w...

Tesla Autopilot workers confirm mass layoff in San Mateo office – Elon Musk - Elon Musk

Image
Tesla’s mass layoffs reached the Autopilot team in San Mateo. Autopilot workers have started posting the news on LinkedIn.  People familiar with the matter told  Bloomberg  that Tesla laid off about 200 Autopilot workers from its San Mateo office. San Mateo had around 350 employees before the recent layoffs. Tesla transferred some of the San Mateo staff to a nearby facility in previous weeks.  The Autopilot team in San Mateo worked on customer vehicle data, specifically data labeling, for Tesla’s autonomous driver assistance features. According to a source, most of the employees Tesla laid off were hourly workers from the Autopilot Team. Most of the San Mateo office staff were data annotation specialists who held hourly positions.  One data annotation specialist, Caesar Rosas, shared that he received the news of Tesla’s layoffs recently. He stated that almost everyone working at Tesla’s San Mateo branch was laid off, adding that he didn’t get to s...

Sen. Joe Manchin blasts EV tax credit expansion, calls for hydrogen development

West Virginia Democrat Joe Manchin blasted a potential expansion of the electric vehicle (EV) tax credit on Thursday, while also calling for the development of the hydrogen sector to decarbonize the transportation industry. Manchin, who called a Biden administration proposal to broaden the EV tax credit program “ludicrous,” said the waiting period for EVs right now is already so long that there is no point to offering more money to incentivize consumers to buy a battery-powered car. “There is a waiting list for EVs right now, with the fuel prices, but they still want us to throw a $5,000, or $7,000 or $12,000 credit for us to buy electric vehicles,” said during a Thursday Senate budget hearing. Manchin added that production volumes of EVs are far away from fulfilling current demand levels, so it would be ridiculous to offer additional funding to the programs. It is evident that EVs are becoming more popular, and with automakers in nearly all situations relating to EVs still workin...
