For example, Luminar claims its lidar has an industry-leading viewing range of 250 meters. The company’s sensors are expected to hit the sweet spot for automakers, costing under $1,000 per unit while offering very strong performance relative to their price. Luminar, on the other hand, is focused on building sensors that can be used in mass-market vehicles. The company posted revenues of over $100 million in 2019, down from about $142 million in 2018, due to lower average selling prices and a larger mix of lower price sensors sold. Based on cumulative shipments and revenue data from the company’s form S-1, its sensors cost an average of $14k per unit. The company’s sensors (such as the 360-degree units that are placed on a vehicle roof) are typically used in prototype self-driving cars and other relatively lower volume applications such as research and development. Velodyne has largely focused on high-performance, high-cost lidar sensors. Luminar’s Tech Hits The Sweetspot For Mass Market Let’s take a look at the two companies’ businesses to understand what’s driving the disparity in their valuation and which could be the better pick. Velodyne - which is actually the more established player in the lidar market - is valued at under $4 billion, or a P/S multiple of about 25x.Luminar’s market cap stands at roughly $10 billion, trading at over 350x projected 2021 revenue,.However, the two stocks are valued rather differently. Lidar - a laser-based technology, which essentially helps computers detect surrounding objects - is poised to grow meaningfully, driven by the broader adoption of self-driving cars, helping both companies. Velodyne Lidar (NASDAQ: VLDR) and Luminar Technologies (NASDAQ: LAZR), two companies that specialize in lidar technology, went public this year.

If you’re looking for an ant proof pet bowl, I’ve got a number of recommendations here, but the WDD Design Co’s 3-in-1 Ant Free Pet Dish looks like one of the better options out there. But this is a really specific kind of situation, and one I’d recommend a different technique for.Ģ. Other than that, in certain cases, if a cat with an approved microchip or RFID tag stands in front of the feeder and another cat stands right next to it, the food thief can eat at the same time as the pet the food is intended for. If this is hard for you to do, this may not be the feeder for you. Is there a downside to these? You should definitely be keeping this one dry. It works well if you have one cat who likes to polish off all the food at once, and another who likes to graze though out the day as well, as that way the grazer can continuously come back to eat without having all the food stolen by the food-polisher. The concept of microchip pet feeders is that pets that stand directly in front of them that have either an approved RFID tag or an approved microchip number will be allowed access to the food, while for others, the plastic cover will remain closed for. If you’re looking for something to help keep your cat’s food safe from the prying hands of raccoons as well as from strays and feral cats and other animals around the area, the SureFlap feeder is an excellent way to go. Automatic Pet Feeder – Sureflap – SureFeed Microchip Pet Feeder Outdoor Cat Feeding Stations Part I: The Bowls & Feeders 1. Still, it’s quite an easy fix with a really inexpensive bowl if you have no other problems to deal with, and if you need food dripping in throughout the day, I’ve come up with a solution for my indoor boys that would work very well for outdoor cats as well.īut I have a lot to cover, so let me just jump in without more discussion here in the intro. Eating too fast isn’t the worst problem a cat can have, although it can lead to vomiting or indigestion. I also mention a few options that may help you out if you have a cat who likes to eat regularly though out the day, but has issues with weight gain if you leave out too much food, as well as for cats who (like mine) eat food way too quickly, scarfing down food faster than lightening if left to their own devices. Part I includes discussion on the bowls and feeders that are excellent at solving mostly pest related problems, from ants to stray cats who may also be after your outdoor cats’ dinner, to those extra-tricky raccoons who heaven knows can be ridiculously hard to work around in terms of how dexterous they are and how clever they can be. To break up this article in a way that made sense, I’ve split the discussion on outdoor feeding stations for cats into two. There’s a lot you can do to tackle problems you might have, and while none are completely weather and pest proof, you may find the perfect combination that deters all of the issues you’ve been having just enough that you can live with any of the remaining problems without being too bothered.Ĭat Catch Interactive Feeder Bowl – Amazon / Chewy Not only is it tricky making sure food bowls stay clean and dry when bad weather hits, it’s also incredibly tricky at times protecting cat food from pests like ants and other insects as well as raccoons, birds, and other larger animals that may get to a cat’s food before he or she can even have a bite. There are a lot of things to consider when it comes to creating ideal feeding stations for outdoor cats.

The telescope has revolutionized our understanding of the universe and has provided us with a window into the mysteries of space. From a simple device that could magnify distant objects a few times, it has evolved into a powerful tool that can reveal the secrets of the cosmos. In conclusion, the telescope has come a long way since its humble beginnings in the early 17th century. In recent years, the discovery of numerous exoplanets has sparked renewed interest in the search for extraterrestrial life. Telescopes have also been used to study the properties of exoplanets, which are planets outside our solar system. The development of digital imaging technology has allowed astronomers to capture images of distant objects with unprecedented clarity and detail. Today, the telescope is used for a wide range of applications, from astronomical research to surveillance and military reconnaissance. The most famous example of a reflecting telescope is the Hubble Space Telescope, which was launched into orbit in 1990. Reflecting telescopes also eliminated the problem of chromatic aberration, which had plagued refracting telescopes. This led to the development of the reflecting telescope, which had a much larger aperture than the refracting telescope and could gather more light. Telescope makers began to use mirrors instead of lenses to focus light. In the 18th and 19th centuries, the telescope underwent another transformation. These improvements allowed astronomers to see even more distant and faint objects in the night sky. They also discovered that adding a second convex lens to the device could increase its magnification even further. Astronomers began to experiment with different lens shapes and sizes, as well as different materials for the lenses. Over the next few decades, the telescope underwent a number of improvements. Galileo’s discoveries provided evidence for the heliocentric model of the solar system, which placed the Sun at the center and the Earth and other planets in orbit around it. These observations challenged the prevailing view of the cosmos, which held that the Earth was at the center of the universe. He quickly discovered that the telescope allowed him to see things that were invisible to the naked eye, such as the moons of Jupiter and the phases of Venus. In 1609, he heard about the device and set about building his own. One of the first astronomers to use a telescope was Galileo Galilei. Nevertheless, they were a vast improvement over the naked eye, and they soon caught the attention of astronomers. They were often only a few inches long, and their magnification was limited to a few times the naked eye. The first telescopes were relatively simple devices, consisting of a convex objective lens and a concave eyepiece. In 1608, they presented their invention to the States General of the Netherlands, who were impressed by its potential and granted them a patent. They were both Dutch spectacle-makers, and it is believed that they used their knowledge of lenses to create a device that could magnify distant objects. The history of the telescope can be traced back to the early 17th century, when two men, Hans Lippershey and Zacharias Janssen, are said to have independently invented the device. In this essay, we will explore the origin and evolution of the telescope, from its earliest beginnings to its modern-day applications. There are different types of telescopes, including refracting telescopes, reflecting telescopes, and catadioptric telescopes, each with its own advantages and disadvantages. In astronomy, telescopes are used to observe and study celestial objects such as stars, planets, galaxies, and nebulae. Telescopes can be used for a variety of purposes, including astronomy, birdwatching, surveillance, and even hunting. Telescopes come in different shapes and sizes, but they all have two basic components: an objective lens or mirror that gathers the light, and an eyepiece or camera that magnifies the image. The main function of a telescope is to make faraway objects appear closer and clearer than they would appear to the naked eye.
