Tele-operators' judgments of their ability to drive through apertures
HRI '09: Proceedings of the 4th ACM/IEEE international conference on Human robot interactionPages 249–250https://doi.org/10.1145/1514095.1514160It has been suggested that operators should base decisions to enter apertures on their ability to control the robot, rather than its static dimensions. Doing so, however, assumes that operators know whether they can drive a robot through the aperture. ...

Cutting Metastability Using Aperture Transformation
IEEE Transactions on Computers (ITCO), Volume 53, Issue 9Pages 1200–1204https://doi.org/10.1109/TC.2004.59Aperture transformation reduces metastability by trading unsafe edge arrival times with control signal metastability. We improve this further by providing 1) a new runt-free Schmitt trigger-based hardening technique using a controlled clock signal and 2)...

Coherent array imaging with sparse arrays
For coherent, phased-array imaging systems, sparse arrays are often used in which the aperture is not completely filled by the array. Often, the data that are not collected by the array are set to zero and an image is obtained through a straight-forward ...

Real-time focus range sensor
Structures of dynamic scenes can only be recovered using a real-time range sensor. Depth-from-defocus offers a direct solution to fast and dense range estimation. It is computationally efficient as it circumvents the correspondence problem faced by ...

Numerical analysis of coax step discontinuities
The paper presents a method of moments (MOM) numerical analysis of coaxial waveguide outer-conductor step discontinuities. An aperture is associated with each planar step discontinuity, and higher-order mode contributions from discontinuities are ...

Active Stereo: Integrating Disparity, Vergence, Focus, Aperture and Calibration for Surface Estimation
IEEE Transactions on Pattern Analysis and Machine Intelligence (ITPM), Volume 15, Issue 10Pages 1007–1029https://doi.org/10.1109/34.254059An approach to integrating stereo disparity, camera vergence, and lens focus to exploit their complementary strengths and weaknesses through active control of camera focus and orientations is presented. In addition, the aperture and zoom settings of the ...

Statistical Analysis of Inherent Ambiguities in Recovering 3-D Motion from a Noisy Flow Field
IEEE Transactions on Pattern Analysis and Machine Intelligence (ITPM), Volume 14, Issue 10Pages 995–1013https://doi.org/10.1109/34.159903The inherent ambiguities in recovering 3-D motion information from a single optical flow field are studied using a statistical model. The ambiguities are quantified using the Cramer-Rao lower bound. As a special case, the performance bound for the ...

Automated printed circuit routing with a stepping aperture
Communications of the ACM (CACM), Volume 12, Issue 5Pages 262–265https://doi.org/10.1145/362946.362973A computer program for routing interconnections on a two-sided printed circuit board with a regular pattern of lines, pins (terminals), and vias (feed-through holes) is described.
In this program, each interconnection is given a planned routing—typically,...
