Velodyne Labs If you want to know the future of laser radar in advance, the best way is to go to Veledne Labs in Almeida. After that, you will see what is called an innovation team. They have been pushing the laser radar technology to the limit and making the future road safer and more efficient. “We are changing the way lidar technology is applied to autonomous vehicles and continuously improving its perception,†explains Velodyne Labs CTO Anand Gopalan. The operation of Velodyne Labs looks more like a design center or incubator. Its mission is to quickly design sensors that can be mass-produced at the company's San Jose Super Factory. This lab is unique among a large number of R&D institutions because it is more like a conceptual design center, and once it comes up with a conceptual design, it can be transferred to the next project. According to Lei Feng, the first task of Velodyne Labs is to make the laser radar more reliable and cheaper by using its own ASIC technology. In addition, they are responsible for the development of their own sensor kits. In terms of the working environment, Velodyne Labs also has its own characteristics. The pace of work here is very fast, but the engineers can also enjoy full cooperation. The founder and CEO of the company, David Hall, will also come to exchange ideas with you. The hardware environment is even more enviable, and employees can look out over the Auckland skyline and San Francisco Bay while they are working. In addition, there is a food street near Velodyne Labs, which is definitely a good place to go after work. At the same time, it has become a paradise for many people who are tired of the pace of life in San Francisco. Right now, the Velodyne Labs office has a total of 45 employees, and the lab plans to double the number of employees over the next year. Today, there is a shortage of electronics engineers, FPGA designers, firmware engineers, and computer vision experts. “As we did 20 years ago, we are still doing something that makes the world a better place,†Anand added.
A: The material is Nickel Metal Hydride (NiMH) which has many advantages over other battery construction materials.
A: Older generation and batteries with other chemical make-up were subject to a memory effect. This is when a battery must be fully drained before recharge or their capacity is reduced. The New Generation of NIMH batteries do not develop a memory effect and can be recharged at anytime during usage cycle. When uncertain about battery charge level or condition, recharge it.
A: This is a rating of energy storage capacity mAh = [milli-ampere hours". So if you are comparing batteries to a AA with a 2000 mAh rating, it will have twice the capacity of a 1000 mAh rating.
A: Most all applications where there is a high energy consumption and demand, is where NiMH belongs. The most popular applications are digital cameras, flashlights, and toys. If you find yourself constantly buying alkaline batteries for an application, then you should consider using rechargeable NiMH.
A: Lower capacity rechargeable AA batteries of 1700 up to 2000mAh can be recharged up to 1000 times in overnight slow charge mode, while 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode.
The new higher capacity AA 2500 mAh rechargeable batteries have greater power capacity, but they can only be recharged approx 500 times in the overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell available on the market above 2100 mAh will have below 1000 charge cycles.
A: Any situation where the battery is not used within a 30 day period or low energy draw devices, for example smoke alarms, emergency flashlights, clocks, TV remotes, etc.
A: NiMH batteries self discharge about 1% per day so if used in a low energy consummation or stand-by device, the battery will only last about 90 days before requiring recharge.
A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use.
A: In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80% of their discharge cycle. Once alkaline batteries discharge to 50% capacity, it will be delivering a lower voltage than a NiMH battery.
A:
A: Yes, but nothing drastic. About 10 to 15% of the battery mAh capacity will be lost at the 400 to 800 recharge level. This will vary greatly because of battery and charger quality, along with how the consumer treats their batteries.
