We describe a sensory augmentation system designed to provide the visually disabled with a sense of color. Our system consists of a glove with short-range optical color sensors mounted on its fingertips, and a torso-worn belt on which tactors (haptic feedback actuators) are mounted. Each fingertip sensor detects the observed objectpsilas color. This information is encoded to the tactor through vibrations...
This paper describes a lighting network proposal, named LightNet, for remote monitoring and controlling of lighting nodes, being lighting lamps and local environment sensors. The network is based on the Controller Area Network (CAN) bus protocol. The LightNet was experimentally implemented using CAN 2.0A with only six network node, but the proposal can be expanded up to 2048 nodes. The LightNet system...
This paper describes a new embedded system based on CAN bus protocol for remote monitoring and controlling of lighting networks, where the network nodes are lighting lamps and environment sensors. The main characteristic of the embedded system is its non-master capability, allowing interesting applications such as: light dimming control of a single lamp, or a group one, through one lighting network...
Measuring the flatness of a cold-rolled steel strip or aluminum foil is a vital aspect of production quality control. Cold lamination control based on the results of this measurement crucially affects production efficiency, but further processes can modify flatness, which can be lost when the strip becomes cold. We describe a low-cost flatness measurement system to monitor this property at several...
A digitally addressable digital dimming electronic ballast based on the CAN Bus protocol has been developed. The ballast is a basic lighting component of a novel lighting system proposed for this work based on this protocol. A digital dimming electronic ballast design, a lighting system structure scheme based on CAN Bus and a software platform to control the ballast by a personal computer are presented.
