Gyroscopic Public Transit Concept Hovers Above Traffic at Varying Heights

26 Aug

[ By SA Rogers in Conceptual & Futuristic & Technology. ]

In this strange vision of a city in the not-so-distant future, disc-shaped public transit, emergency vehicles and cargo vehicles rise up above traffic on vertical supports to zoom through the streets unimpeded, lowering to the ground at designated stops. Created by designer Dahir Insaat, ‘Gyroscopic Transport’ looks like an alternate take on China’s traffic-straddling bus (which turned out to be a giant traffic-snarling scam, by the way.) Could this new proposal be any better?

In a video announcing the concept, Insaat explains how the technology works and lays the groundwork for gyroscopic vehicles with the potential to be more successful than their predecessors. Taking inspiration from recent developments in the area of electric motor control, Insaat developed a gyro car that “meets all current safety requirements.” Noting that it’s financially and often physically impossible to significantly expand roads in existing cities, the designer suggests that we take to our “unused road medians” as a solution.

The Gyro car could fit into existing roadway infrastructure while remaining independent from the flow of regular motor vehicle traffic below. It can elevate high enough on its supports to safely pass over most vehicles, running along a special fortified strip between lanes. The car itself has a lightweight body and can either be designed with mass transit interiors to fit large groups of passengers, or as luxurious lounges. In the video, the designer also explains how the concept could extend to emergency responders like firefighters.

Of course, the concept hasn’t avoided criticism and questions as to its feasibility. What happens when a vehicle hits its support pillars at high speed, for example? These kinds of technical details don’t seem fully fleshed out yet, but it’s an interesting idea, and watching the pods navigate traffic circles is kind of mesmerizing.

Canon releases new firmware for EOS 5D IV to correct varying flash color

30 Nov

Canon has introduced an update for its EOS 5D Mark IV DSLR that corrects a color issue when using flash, and improves the camera’s performance when the company’s new tele-converters are in use.

Firmware version 1.0.3 fixes an issue that created different color temperatures in flash output according to the metering mode in use at the time, and makes communication between camera and lens more reliable with the EF1.4x III and EF2x III tele-converters. The company says an additional fix corrects the way the level gauge is displayed when the camera is held in portrait orientation with the grip below the lens.

For more information visit the Canon website.

Manufacturer’s release notes

Changes in the Firmware

Firmware Version 1.0.3 incorporates the following fixes and improvements:

1. Corrects a phenomenon in which the color of images varies depending on the metering mode selected during flash shooting.

2. Improves the reliability of communication when using the EF1.4X III or EF2X III extender.

3. Corrects the level display when the camera is held in the vertical orientation with the hand grip pointing downward.

4. Improves the reliability of communication via USB cable when using the Lens Data Registration function with EOS Utility 3.

Firmware Version 1.0.3 is for cameras with firmware Version 1.0.2 or earlier. If your camera’s firmware is already Version 1.0.3, it is not necessary to update the firmware.
When updating the firmware of your camera, please review the instructions thoroughly before you update the firmware.
