The document discusses an embedded system project that uses infrared sensors to detect obstacles and avoid collisions. The system includes IR sensors connected to a microcontroller that processes the sensor inputs. When an obstacle is detected, the microcontroller activates a buzzer or moves DC motors to maneuver around the obstacle. The system has potential applications in automobiles to help reduce accidents by detecting obstacles and notifying the driver. However, infrared sensors require a direct line of sight, so ultrasonic sensors could improve obstacle detection capabilities.

This document discusses a research project using MEMS "smart dust motes" for intelligent lighting control. The goals are to use wireless sensor networks to better understand occupancy patterns, validate sensor readings, and optimize lighting for energy savings while considering user preferences. Researchers plan to characterize mote sensors, develop validation and fusion algorithms, and eventually implement a smart lighting system in the BEST Lab to automatically control dimming based on human presence and interactions. This would personalize lighting while reducing electricity costs.

HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
