  • Publication number: 20140213917
    Abstract: A biofeedback device and the light sensor used thereby are described herein that can be mounted on or integrated with eyewear such as swimming goggles. The biofeedback device may include a heart rate measurement apparatus comprising a reflected green light sensor, and first, second, and third green light emission elements. The biofeedback device may include a housing having a first portion and a second portion, which each of the first and second portions having a first side and a second side. At least a portion of the heart rate measurement apparatus may be disposed within the housing first portion and may be exposed through an opening in the second side of the housing first portion. The biofeedback device may also include an opening that allows the device to be removably engageable with at least a portion of the swimming goggles.

  • Patent number: 5926290
    Abstract: The invention relates to a document-tray driven apparatus for a photo drive for reading information off a transparent sheet or a reflective sheet. The invention mainly comprises a paper feeding device, a driving device, a lower illumination device, an upper illumination device and a photoelectric converting device. The exposure of the original sheet depends on the motion of the paper feeding device. As the paper feeding device is moving, the scanning process takes place simultaneously. This design allows all other optical members to fix on the housing. Thus, it makes the light path easier to control and the quality of the image scanned will be improved thereby. Moreover, since the driving device is installed at a single side of the housing, the space inside the housing can be utilized more efficiently.
