An Inside Look At The Automotive Ethernet Protocol
Aug 6, 2018 · Automotive Ethernet provides higher bandwidth data transmissions compared with LIN (19.2 kb/s), CAN FD (15 Mb/s), FlexRay (10 Mb/s), and MOST (25, 50, or 150 Mb/s shared). The LIN protocol really only sees usage for very low-bandwidth applications controlling body electronics such as windows or lights. CAN and/or CAN FD offers a flexible data ...
Basics of understanding signal jamming: What you need to know
Mar 6, 2019 · Many of the sophisticated advances in signal jamming arose from work with radar. So it is useful to start with a review of a few radar fundamentals. The idea of radar, of course, is that a target reflects some of the energy of a transmitted signal. The returned energy is received and processed to detect the target and extract its location and ...
Understanding the Automotive SENT Protocol Explained
Jun 28, 2024 · The Single Edge Nibble Transmission (SENT) protocol defines an approach to data communications in accordance with the Society of Automotive Engineers (SAE) J2716 standard. SENT provides a rugged, low-cost way of transmitting high-resolution data from a sensor to an engine control unit (ECU) or another controller.
Key design considerations for sheet metal enclosures
Sep 5, 2018 · Sheet metal parts are manufactured from a single sheet. You cannot have a 14ga (gauge) base with a 16ga flange with formed parts. This would require welding two components of differing thicknesses together. The 4 x Rule (4 x material thickness). Flange length must be a minimum of 4x material thickness. This is due to the need to maintain three ...
The hot-wire anemometer, Part 1: Principles
Mar 20, 2020 · The hot wire anemometer for measuring fluid speed offers unique advantages but also has some challenging use issues. You are undoubtedly familiar with the classic wind-speed anemometer with three cups rotating as the wind blows, while a tachometer reports the revolutions rate (Figure 1).This is a “tried and true” way to measure large-scale wind speed.

Sep 23, 2021 · Switches: The complete guide. September 23, 2021 By Aimee Kalnoskas. From DIP, rotary DIP, and slide switches to tactile, rocker, push button, and toggle switches, there is a nearly limitless range of mechanical switches differing in size, shape, interfaces, and features. Although a relatively basic component in electronic design, each switch ...
FAQ: Ground rules: earth, chassis, and signal ground
Oct 28, 2016 · A chassis ground is a ground-collection point that connects to the metal enclosure of an electrical device. A chassis ground may be used for shielding and grounding to prevent electrical shock. Mains’ earth ground and the (theoretically) 0V power rails are all tied together and connected to the chassis at that one point.
Practical electromagnet design - Electrical Engineering News and …
Dec 26, 2016 · We then calculate the MMF density (H) by dividing the MMF by the length of the electromagnet core in meters. So if your electromagnet is 0.02m (2cm) long, H would be 10AT/0.02M =500AT per meter. But H will not be used in the practical formula that described below. Instead, the AT and electromagnet length will be used directly, as these are the ...
