This letter describes the development of a humanoid arm with quick-and-wide motion capability for making humans laugh. Laughter is attracting research attention because it enhances health by treating or preventing mental diseases. However, laughter has not been used effectively in healthcare because the mechanism of laughter is complicated and is yet to be fully understood. The development of a robot...
TCP/IP offload engine (TOE) is an essential technology to increase throughput of network connection. In this paper we present a novel approach for TOE implementation in embedded system with very stringent requirements on area and power. Our approach is based on two design optimizations. The first one deals with architectural enhancement for reducing the size of memory buffers in TOE hardware. The...
This paper presents a new architecture and circuit implementation of 1-D median filter. The proposed circuit belongs to the class of non-recursive sorting network architectures that process the input samples sequentially in the word-based manner. In comparison to the related schemes, it maintains sorting of samples from the previous position of the sliding window, positioning only the incoming sample...
This paper introduces a prototype hardware design for detecting user's presence in front of computer-based video camera. The hardware implements basic image processing techniques (filtering, color-based segmentation, thresholding) producing a signal when a human-skin color segment is detected in the image frame. Experiments show that the design allows real-time user monitoring (30 fps) with 82% detection...
This paper introduces a prototype hardware design for camera-based power management of computer display. The design keeps display active only when the computer user is actually present. Otherwise it switches the display off to save energy. The hardware operates in real time (30 fps) and consumes only 150 mW of power; 35 times less than software implementation.
