3-layer LED headlamps

Three-layered LED headlights include 84 individual controllable LEDs per headlamp that vary light distribution depending on traffic, weather, and road conditions. The integrated adaptive high beam assistant allows more frequent use of the vehicle’s high beams, offering greater safety and comfort. The module includes 84 LEDs arranged in three lines that can be controlled individually, allowing precise control of the light pattern for both high and low beams without the need for mechanical actuators.

Transparent silicone plastics are being used as the primary optics for an LED headlamp, replacing thermoplastics. Silicone is resistant to the high energy radiation of LEDs and, in contrast to glass, can be machined more precisely to meet strict tolerances in the manufacturing process.

Automotive LED driver

The S6BL112A automotive LED driver enables smaller, more cost-effective headlight systems. The driver features synchronous control, enabling high conversion efficiency for stable performance in a lighting system. The device is able to drive LEDs at a 2.1MHz switching frequency, enabling a compact headlight solution that uses small, inexpensive inductors, reducing physical size and bill-of-materials costs.

The LED drivers combine with Traveo microcontrollers (MCUs) and power management ICs (PMICs).

The LED drivers feature 4.5V to 42V input voltage, encompassing extreme operating conditions such as cold-cranking or load dump. The LED driver also facilitates the design of electrical system safeguards by including system safety functions such as under-current detection, over-current and voltage protection, and the ability to mask undesired LED open diagnosis during cold cranking. Synchronous operation eliminates unstable dimming that can occur when the input voltage is low.

The one-channel 2A output Buck LED driver supports analog and PWM dimming functions, enabling precise brightness control. Its switching frequency can be set between 205kHz and 2.1MHz, with high output current accuracy of ±2%. The device enables slew rate control without an external filter, limiting electromagnetic interference (EMI) generation.

Industrial computers

RCO-1000, RCO-3000, and RCO-6000 series fanless PC computers incorporate Intel Bay Trail, Broadwell-U, and Skylake processor support respectively. The cable-less models support extended operating temperature of -25°C to 70°C, 9VDC to 48VDC input with over/under-voltage and reverse polarity protection, 5Grms vibration, and 50G/11ms shock protection.

PCs are built with one-piece extruded aluminum, and each has several form factors to support different I/O and expansion requirements. Custom I/O cards are available to bring additional I/O out without internal cabling. For example, COM port, DisplayPort, Digital I/O, and 4-port Gigabit Ethernet (with or without 802.3at PoE) in RJ-45 or M12 connectors expansion can be added.

All models come with the option of dual SIM card slots to support cellular network connection. Two mini-PCIe slots and multiple SMA antenna cut-out holes let system engineers have configure different radios and network connections.

Exhaust gas recirculation valve

Designed for Hyundai’s 1.6L gasoline director injected (GDI) Kappa engine, exhaust gas recirculation (EGR) valves lower emissions and boost fuel economy by 3%. The valves regulate exhaust gasses throughout a range of rpms and loads, reducing high temperatures in the combustion chamber and enabling a variety of strategies aimed at improving engine efficiency and fuel economy.

Using cooled EGR manages pumping losses to help the engine run more efficiently, improves combustion timing for a leaner burn without knocking, and helps avoid using enriched fuel/air mixtures, which saves fuel. The technology also reduces carbon monoxide (CO) and nitrogen oxide (NOx) emissions as well as particulate matter (PM). The EGR valves deliver accuracy by measuring valve lift directly. The simplified, low-leak design also resists sticking and uses fewer parts in the gear train, resulting in a compact, cost-effective solution with 25% faster response compared with previous models.

Heavy-duty truck engines

The X series of diesel engines expands to three models with 350hp to 605hp. Big bore X15 Performance and X15 Efficiency engines and medium-bore X12 engines are optimized for specific duty cycles and applications. The engines meet Phase 1 greenhouse gas (GHG) and fuel-efficiency standards set to be implemented in 2017.

Performance and fuel efficiency come from optimized compression ratios, air handling systems, and cam profiles.

All three engines use the Single Module aftertreatment system which is 60% smaller and 40% lighter than other diesel cleaning systems. It can extend diesel particulate filter ash-cleaning events to as many as 800,000 miles on the X15 line.
