超声波雷达（USS，Ultrasonic Sensor System）价格低廉（单个数元至十元人民币），检测距离短，是泊车功能的重要传感器，此外车身侧面的超声波雷达（APA）也会作用于行驶横向辅助报警功能。

USS Cod (SS/AGSS/IXSS-224) is a Gato -class submarine, the only vessel of the United States Navy to be named for the cod, an important and very popular food fish of the North Atlantic and North Pacific oceans. She was launched on 21 March 1943, and commissioned on 21 June 1943.

A thin, flat, circular metal part with a centrally located hole. USS washers are similar to SAE washers, but with inner and outer diameters slightly larger. Applications/ Advantages: Washers are intended to be mounted around a bolt or screw, between the fastener's bearing surface and the portion it is connected to.

2024年7月30日 · 超声波雷达Ultra Sonic System，简称USS，也叫倒车雷达，是一种很常见的传感器，它的工作原理是利用超声波发射装置向外发射超声波(是机械波不是电磁波)，至利用接收器接收到发送过来超声波时的时间差来测算距离。

2024年12月23日 · The main difference between U.S.S. and SAE pattern flat washers is their outside diameter (OD). For a given inside diameter (ID), a U.S.S. washer will have a larger OD than an SAE washer. Historical context and applications of each pattern:

Our standard admission prices are $15 for adults, $13 for seniors (62+) and veterans with ID, $9 for youths (grades K-12). Pay at the gate. School field trips to COD are very popular and are encouraged as an educational and entertaining experience for youngsters. Free parking and discounts from the already nominal admission fees are provided.

超声波雷达USS模块的工作原理是通过超声波发送探头向外发送超声波,超声波在向外扩散过程中遇到障碍物就会产生反射波,然后通过接收探头对反射波进行接收,通过发送和接收到超声波的时间差来计算障碍物的距离,如图3 所示。 常用的探头工作频率有40KHz,48KHz 以及58KHz,一般来说频率越高,灵敏度越高,但是水平以及垂直方向的探测角度FOV 就越小,所以一般就采用40KHz 的探头。 超声波雷达不受烟雾影响,探测距离一般在0.1~3米之间,精度可以达到毫米级别。 超声波的速 …

USS washers typically have larger diameters than SAE washers to accommodate larger nuts and screws and to distribute pressure across a wider surface area. They are also thicker, so they withstand heavier loads and span wider gaps when used as spacers.
