New inductive-technology position sensors

Novotechnik's TF1 Series touchless linear position sensors overcome issues with legacy magnetostrictive technology. They are unaffected by strong magnetic fields and metal flakes or filings present in a user's environment. The TF1 Series consists of an inductively coupled position marker attached to a moving rod/piece of the user's application that requires a position measurement and the sensor with operational and programming status LEDs. While operating, LEDs indicate whether the sensor is operating and the marker within measuring range or out of range, as well as indicating results of internal diagnostics for valid output from the sensor. Can also measure speed and temperature.

How electronic flow sensors help spread road salt

Salt spreading trucks use a pre-wetting system when ice needs to be removed from roads and the temperatures are too low for direct salt spreading to work. The system sprays salt water onto the road salt as it is being spread to "jump start" the melting process. But how do you monitor the amount of pre-wet salt used?

How to convert from hydraulic to electric high-force linear actuators

Machine designers are converting existing linear motion systems from hydraulic to electric due to the technology's many benefits, but the process involves considering the actual force output of the cylinder, the duty cycle, and the motion profile. Specialists at Tolomatic tackle these points. Includes a very informative video.

20-in. automotive touchscreens enabled by new controllers

With cars like the Tesla Model S featuring 17-in. touchscreens, the trend in automotive displays is to go bigger and bigger. But unlike handheld mobile devices, screens in automobiles need to meet stringent head impact and vibration tests, so they have thicker cover lenses that potentially affect the touch interface performance. As screens get larger, they are also more likely to interfere with other frequencies and car access systems. These factors pose a major challenge in the design of modern automotive capacitive touch systems, but a new family of single-chip maXTouch touchscreen controllers from Microchip Technology was designed to address these issues.

Hyundai Motor Group develops smartphone-based digital key

Hyundai Motor Group recently announced the development of a "Digital Key" that allows users to unlock and start their Hyundai vehicle via their smartphone. Replacing a traditional physical key, the new Digital Key can be downloaded via an app and used by up to four authorized people.

The Digital Key can be downloaded via a cellphone application, and Near Field Communication (NFC) technology detects the presence of an authorized Digital Key-enabled cellphone in close proximity to the vehicle door.

The NFC antenna for entry identification is located in the handles of the driver and front passenger doors, while one for starting the engine is located within the wireless charging pad inside the car.

After unlocking the vehicle, the user can start the engine by placing the smartphone on the wireless charging pad in the center console and pressing an engine Start/Stop button on the dashboard.

The user's preferred vehicle settings are stored in the vehicle. When the key is recognized, those settings are adjusted automatically, including the position of mirrors, seats, and the steering wheel, as well as controls for the audio, video, and navigation (AVN) systems and head-up display.

Hyundai's Digital Key can be used to control selected vehicle systems remotely via a smartphone. Using Bluetooth Low Energy (BLE) communication, users can lock and unlock the vehicle, activate the alarm, and start the engine. In addition, once the vehicles with autonomous parking features are commercialized, such features are also expected to be remotely controlled.

The level of access to different vehicle functions can be tailored to each user, for a defined period. The vehicle owner can preset the duration of vehicle use or limit the use to only certain features when renting the vehicle. For instance, it can even be used to enable a courier to open the trunk to deliver a parcel.

Hyundai is betting that once car sharing becomes more widespread, the Digital Key will be further programmed to support hassle-free vehicle rental where the owner and the driver won't have to meet but can transfer the Digital Key via the cell phone application.

As well as making it much easier for a Hyundai vehicle to be included in a car-sharing program, the Digital Key will be further enhanced in the future to allow for features such as an alarm to be triggered when the vehicle exceeds a defined speed or travels outside a designated area.

For cases such as using a valet service or visiting a repair shop, where handing over a digital key is not feasible, conventional smart key and card-type key are also provided.

Hyundai Motor Group aims to gradually implement the technology in its new production vehicles, starting later this year.

NFC is a form of Radio Frequency Identification (RFID) that boasts a high level of security. The NFC wireless data communication takes place only when the device and the reader are placed several centimeters apart.

"The Digital Key will benefit a very wide range of future Hyundai customers, as well as enabling innovative new schemes for vehicle sharing," said Ho Yoo, Group Leader of Hyundai Motor Group's Electronics Development Group. "We are studying other ways to harness this type of connected-car technology to greatly enhance the driving and ownership experience."

No one has commented on how the car will be started if the phone battery is dead and the driver is not carrying a physical key.
