The present home security system needs an LCD screen that is located somewhere inside the home to view the camera video. At some point of time, consider the time when you are watching a very interesting program in the television, may be the last over of a T-20 match or the final minutes of a soccer match, your mind won't allow you to think of anything else than the ongoing match. At this circumstance, when anyone rings your door bell, naturally you won't mind that, whoever the guest may be. At another instance, if you are tired of attending unwelcomed guests n times, chances are there to neglect the guest at the n+1th time more consciously. If the guest at the door is an opportunity, it would be evidently missed. Our innovation to conquer this problem is, the video of the person standing at the door is made appeared at the television screen not by replacing the existing cable signal but as a pop up screen which covers a small portion of the TV screen. So, by noticing the pop up, one can decide which is vital — either the TV program or the guest. This pop up disappears automatically after a certain point of time when the guest leaves","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126898499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kishore","doi":"10.1109/INTERACT.2010.5706173","DOIUrl":"https://doi.org/10.1109/INTERACT.2010.5706173","url":null,"abstract":"In Very Deep-submicron (VDSM) systems, the scaling of ULSI ICs has increased the sensitivity of CMOS technology to cause various noise mechanismssuch as power supply noise, crosstalk noise, leakage noise, etc. In VDSM technology distance between the data bus lines is reduced, so coupling capacitance is dominating factor. Unfortunately, in VDSM systems, the coupling capacitance is of magnitude several times larger than the loading capacitance. The coupling capacitance causes logical malfunction, delay faults, and power consumption on long on-chip data buses. An important effect of the coupling capacitance is Cross talk. Crosstalk is mainly dependent on several factors: drive strength, wire length/spacing, edge rate and propagation duration. The crosstalk noise produces from the coupling capacitance. Such faults may affect data on data bus. To avoid this condition and to guarantee signal integrity on the on-chip communication, a fault tolerant bus can be adopted. This could be achieved by implementing error-correcting codes (ECCs), providing on-line correction and do not require data retransmission. The 4,8,16, and 32-bit data bus is implemented in 180nm, 120nm, and 65nm technologies using Bsim4 model. For reliable transmission of the data ECC techniques is placed on the data bus. We employed a Hamming code and Dual rail as ECC for 4,8,16 and 32-bit fault tolerant data bus. This is implemented in 180nm, 120nm and 65nm technology.

The ground plane, which is captured using a calibrated camera, mounted on a robot platform, has been segmented in a two step process. In the first step which is an offline process, the statistical properties of the ground plane are learned using a robust Gaussian Mixture Model (GMM) based segmentation method. In the online process, the ground plane is segmented using its learned signatures. Planar homography, between the 3D ground plane and the image plane has been used in depth map generation for the segmented images.

However, the lack of haptics feedback in these robotic systems using long teleoperated instruments has negatively affected the surgeon's ability to palpate tissue and diagnose it is healthy or unhealthy. This paper describes the design of a modular, automated laparoscopic grasper with 3D force feedback capability along with Robotic arm. The normal grasping forces, as well as, side ways manipulation forces during grasping and palpation tasks can be measured. Additionally, a modular design allows for easy conversion between surgical modalities. Calibration of the force sensors and initial testing of the prototype has shown its ability to accurately measure tool-tissue interaction forces. A complete Robotic system with tactile feedback consisting of a strain gauge force sensor mounted on Robotic end effector & servo motor based wireless control system has been proposed. A control jig at the master side in a bilateral master slave control setup to simplify the MMI has been proposed and a rotary potentiometer at the master side as a position sensor has been used.

Objects are identified based on their unique color. These visual cues will be removed in the near future so that new vision algorithms are needed to cope with this. In this paper we present a method for detecting and tracking the ball with the help of the color information obtained from the colored object. Our method relies on a two-level approach. On the lower level, to detect the color object controlling the Wireless Mobile robot platform which carries the wireless camera is controlled so as to keep the target at the center of the image plane. On the higher level, the robot operates under the assumption that the camera system achieves perfect tracking. In particular, the relative position of the object is retrieved from the Image coordinates through simple geometry, and used to compute a control law driving the robot to the target. Various possible choices are discussed for the highlevel robot controller.

The problems introduced are perception, basic pose description, transition and sensor models, localization as a special case of perception, representation of environment, path planning (cell decomposition, potential fields, skeletonization, and probabilistic roadmaps), movement of robots, and some real-life examples. The general problem of simulating intelligence has been broken down into a number of specific sub-problems like deduction, reasoning, problem solving, natural Knowledge processing, motion and manipulation, perception and social intelligence, cybernetics and brain simulation. These intelligences together provide better computational robotics named HUMANOID ROBOT. These will prove important in applications like surgical robots, robots for civil use and military robots.

The steganographic method will be used for internet/network security, watermarking and so on. So, the steganography is the process of hiding one medium of communication (Text, Sound, and Image) within another. It can work on JPEG 2000 compressed images & stir Mark images. The new method of steganalysis based on neural network to get the statistics features of images to identify the underlying hidden data. We first extract the features of image embedded information, then input them into neural network to get the output. Experiment result indicates this method is valid in ‘Steganalysis’ The ‘Steganalysis’ is the field of detecting the covert messages. Almost all steganalysis consist of hand-crafted tests or human visual inspection to detect whether a file contains a message hidden by a specific steganography algorithm. The neural network in still images is used to overcome the hurdles by hiding the data indirectly into graphical image using neural network algorithm to get cipher bits, The generated cipher bits are then placed in the least significant bit position of the carrier image. The XOR propagation network model is used which acts as a multilayer perceptron.","PeriodicalId":201931,"journal":{"name":"INTERACT-2010","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132739698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In CDMA system, a large number of users could be served over the same bandwidth by assigning a unique code to each of the users.

In this paper, we have proposed an algorithm to generate an “Orthogonal Minimum Cross-correlation Spreading Code” (OMCCSC), which can provide a large number of distinct spreading codes as compared to the existing orthogonal and near orthogonal spreading codes, namely Walsh code, Orthogonal Gold code and Orthogonal Kasami code. The study of cross-correlation property of the proposed code proves its superiority over other existing codes.
