  • High Power IR LED Driver Using the PIC16C781/782
    Early infrared (IR) remote control systems employed a simple on-off modulation of an IR LED to transmit the control data between the remote control and the appliance. Unfortunately, while this method was simple to implement, it suffered from both interference and range problems. A warm object
  • IR Remote Control Transmitter
    . The infrared spectrum provides less ambient noise than other spectrums of light, like visible PHILIPS RC5 PROTOCOL light, and this makes infrared ideal for inexpensive reliable communication. The RC5 protocol is a common IR transmission proto- To create an IR control link, one needs a transmitter
  • Infrared On-orbit RCC Inspection with the EVA IR Camera: Development of Flight Hardware from a COTS System
    and the flight crews, the team accelerated its schedule and delivered a certified EVA IR Camera system in time to support STS-114 in July 2005 as a contingency. The development of the camera system, led by LaRC, was based on the Commercial-Off-the-Shelf (COTS) FLIR S65 handheld infrared cameras.
  • Infrared Illumination for Time-of-Flight Applications
    ; this might create the perception that TOF systems are rather expensive. This document focuses on Infrared (IR) illumination for TOF systems using Vertical Cavity Surface Emitting LASERs (VCSELs) and Light Emitting Diodes (LEDs) and shows that LEDs are a feasible and affordable option as IR
  • Using IR Surveys in DUNAFERR Steelworks Complex Diagnostic System
    an information and diagnostic system. This paper covers the inception of the IR survey program in the early 1990s, including how the infrared routes were established and the decisions on which equipment would be included in the routes. The IR program generally aimed at the following fields
  • Influence of Gaseous Species on Thermal Infrared Imaging
    measurements are possible. In contrast, the detection of gases themselves with thermal imaging technology is a rather new application which has recently led to the development of GasFind IR cameras.
  • Applying Infrared Imaging Techniques to Marine Surveying ... Combining IR with Audio Gauging
    area, and condition of their surface (e.g. free of calcareous scale). A sacrificial anode that has been accidentally painted with antifouling bottom paint is no longer effective. Such were the events that led up to this inspection. When the anodes are no longer effective, the cathode (in this case
  • Using Infrared Technology for Sensing and Remote Control Application (.pdf)
    Infrared (IR) technology addresses a broad variety of wireless applications, especially in the areas of sensing and remote control. Today's newest products such as cell phones, digital cameras, and DVD players as well as remote controls for every market segment rely on IR sensing and Control
