Toshiba releases split smart glasses dynaEdge: runs on Windows 10 Professional PC

Toshiba recently unveiled its "dynaEdge" AR glasses to the corporate market, offering a discreet and practical solution for professionals. While not the most stylish wearable, what makes dynaEdge stand out is its integration with a full Windows 10 Professional PC, making it more than just an augmented reality device—it’s a portable workstation. Priced at $1,899, the dynaEdge combines elements of Google Glass with a compact, battery-powered Windows 10 PC featuring a sixth-generation Intel processor. This design allows users to run full desktop applications, access files, and even manage business workflows on the go. The glasses are designed for one eye, with a display that can be easily pushed aside when not in use. This makes them ideal for industrial or factory settings, where workers can quickly check lists, view images, or follow step-by-step instructions without being distracted. The non-intrusive design also allows it to be mounted on a hard hat, making it suitable for environments where hands-free operation is essential. The system supports video conferencing, features an embedded camera for capturing content, and displays instructions directly in the user's peripheral vision. Built on Windows 10, it includes security features like an optional fingerprint sensor, meeting the demands of enterprise clients. For businesses looking to integrate AR into their workflow, Toshiba sees a clear advantage in using a Windows-based system. Unlike many Android-powered headsets, this approach may simplify IT integration and reduce training costs. Additionally, the Toshiba brand brings a level of trust and reliability that some companies might prefer over newer, less-established startups. The dynaEdge also offers an AR-optimized interface, allowing users to browse PDFs, stream videos, and scan QR codes seamlessly. With features like a 0.26-inch display, 640x360 resolution, and a 5-megapixel camera, it balances functionality with portability. Other specs include built-in audio, motion sensors, and a USB-C connector for charging and data transfer. At just 47 grams, it’s lightweight and easy to wear for extended periods. Overall, the dynaEdge is a solid choice for enterprises seeking a reliable, secure, and powerful AR solution that integrates smoothly with existing IT infrastructure.

Power Amplifiers

A power amplifier (PA) is a critical audio component designed to take weak audio signals from pre-amplifiers, mixers, or source devices and boost them to levels capable of driving speakers, delivering loud, clear, and dynamic sound. As the final stage in an audio chain, power amplifiers are essential in everything from home stereos to massive concert systems, balancing raw power with precision to ensure audio integrity.
 

Class AB Amplifiers

  • Operation: Combines Class A and B, with transistors conducting slightly more than 180° to reduce crossover distortion.
  • Efficiency: Good (60–70%), balancing sound quality and power consumption.
  • Sound Quality: Low distortion (<0.05%), widely used in home theaters and hi-fi systems.
  • Applications: Home audio systems, studio monitors, and mid-range PA systems.

Class D Amplifiers

  • Operation: Uses Pulse Width Modulation (PWM) to switch transistors fully on/off.
  • Efficiency: High (80–95%), generating minimal heat and requiring smaller heatsinks.
  • Sound Quality: Modern designs achieve <0.1% distortion, comparable to Class AB.
  • Advantages: Lightweight, compact, and energy-efficient.
  • Applications: Car audio, portable speakers, subwoofers, and large-scale PA systems. 
 
Applications Across Industries
1. Home Audio
ï‚·Use Cases: Powering bookshelf speakers, floor-standing speakers, or subwoofers in 2.1/5.1 systems.
ï‚·Example: A 2-channel Class AB amp (100W x2) paired with a CD player and stereo speakers for music playback.
2. Professional Audio
ï‚·Live Events:
ï‚·Large-scale concerts use multi-channel Class D amps (e.g., 4x1000W) to drive line array speakers.
ï‚·Features like bridge mode (combining channels for mono subwoofer power) are critical.
ï‚·Installed Systems:
ï‚·Commercial spaces (hotels, schools) use 70V line amps for distributed audio, ensuring consistent volume across zones.
3. Automotive Audio
ï‚·High-Power Setups: Class D amps (e.g., 2000W mono for subwoofers) deliver deep bass from car batteries (12V systems).
ï‚·Space-Saving Design: Compact Class D modules fit under seats or in trunks without excessive heat.
4. Studio Monitoring
ï‚·Precision Amplification: Class AB amps with low THD (<0.01%) ensure accurate sound for mixing and mastering.
Nearfield Monitors: Dedicated amps for small speakers placed close to the listener in recording studios. 
A power amplifier is the backbone of any audio system, translating electrical signals into the sound that entertains, informs, and moves audiences. Whether delivering subtle nuances in a jazz recording or the thunderous bass of a rock concert, its ability to balance power, efficiency, and precision makes it indispensable in the world of audio engineering.
