  • 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
    AN1064 IR Remote Control Transmitter receiver. The IR light then travels through the air and is Author: Tom Perme detected at the receiver by a photo-diode. The photo- John McFadden diode is often contained in a complete module which Microchip Technology Inc. demodulates the modulated signal
  • Using IR Surveys in DUNAFERR Steelworks Complex Diagnostic System
    to acquaint those who are not familiar with this type of operation. Developments in maintenance have led the staff to utilize an increasing quantity of information to develop an effective maintenance service for the company's worldwide operations. To fulfill the requirement, the company established
  • 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.
  • 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
  • Analysis of HVAC System and Building Performance Utilizing IR, Physical Measurements and CFD Modeling
    Reported problems with recently constructed buildings exposed to severe climatic conditions led to a legal case regarding the performance of the heating systems and the buildings. The buildings were examined using visual methods, infrared imaging, blower door, and flow hood measurements
  • Using Infrared Technology for Sensing and Remote Control Application (.pdf)
    devices. ROHM Semiconductor has been driving technology advances that have led to a growing number of IR sensing and communication applications for over 40 years.
  • Medical Device Link .
    frequency (RF), which can cause interference. An IR wireless interface offers the medical equipment designer a versatile and economic wireless transceiver. The IR transceiver consists of an IR light emitting diode (LED); a p-type, intrinsic, n-type (PIN) diode; and an amplifier application specific
