A walking frame assists in movement, but the orientation and positioning for people with restricted visual ability without external help is nearly impossible. They also have trouble with object recognition to avoid collisions and prevent injuries. Therefore there is the need to assist people with restricted moving and seeing abilities, so that they maintain mobility. The application of the Microsoft Kinect sensor is an effective and low cost method to lead people through the environment with detailed depth information offered by an infrared camera. Additionally, with the help of inertial sensors for navigation, an imaging of the surrounding objects and obstacle recognition is possible. In this paper, orientation and positioning of a walking frame by means of an accelerometer and gyroscope is presented and it is demonstrated how these data supports obstacle recognition with the Kinect. The results and benefits for further usage are presented.","PeriodicalId":284922,"journal":{"name":"2015 IEEE 9th International Workshop on Multidimensional (nD) Systems (nDS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114965664","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}

We consider a general class of linear systems governed by partial differential equations with boundary control. This problem is here treated in a quite natural manner through the freeness property, the analogue of differential flatness for linear systems. Any variable is then expressed as infinite order differential operators applied to the basis components, the analogue of the flat output components. The specialisation of the basis components are functions which are both of Gevrey regularity (in order for the infinite order differential operators to be convergent) and pertaining the flexibility of polynomial splines. An illustration is made through an Euler Bernoulli beam example.","PeriodicalId":284922,"journal":{"name":"2015 IEEE 9th International Workshop on Multidimensional (nD) Systems (nDS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114256742","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}

This paper presents a new approach of a grid based map building algorithm which represents an extension of occupancy grids. As well as it its archetype, the algorithm can easily be used for 2d or 3d time-dependent map building procedures. The original occupancy grids were extended so that cells which are marked as occupied get further differentiated regarding the motion characteristic of their particular obstacle. An occupied cell can therefore be differentiated in a cell occupied by a dynamic, quasi static or static obstacle. This differentiation might also come in handy regarding object detection or similar algorithms. The presented algorithm was developed and tested using a SICK LMS511 high resolution laser measurement system.","PeriodicalId":284922,"journal":{"name":"2015 IEEE 9th International Workshop on Multidimensional (nD) Systems (nDS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131797283","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}

The method employs a parabolic dish and focal plane array (FPA) processor together with a network resonant multi-dimensional recursive digital velocity filter. An FPA-fed parabolic dish antenna creates multiple radio frequency (RF) beams. The RF beams can sense simulated moving objects that are illuminated using mm-wave (90 GHz) RF energy. A 3-D IIR digital velocity filter is applied on the simulated radar signals to enhance signatures that are moving at a direction of interest at a given speed while significantly suppressing undesired interfering signals traveling at other velocities and additive Gaussian noise. A dish of diameter 0.5 m and focal length of 30 cm with an FPA with 4096 antenna elements (64×64) arranged in a dense square array is simulated using an electromagnetic field simulator. The resulting electric field intensity profiles are processed to extract the signatures of interest. Simulation results show an average signal to interference improvement of 7 dB with single interference and 6 dB for multiple interference. Proposed method exhibits an average signal to interference and noise ratio (SINR) improvement of 6 dB for input SINR of -15 dB. All results are simulation based. No fabrications have been attempted at this point.","PeriodicalId":284922,"journal":{"name":"2015 IEEE 9th International Workshop on Multidimensional (nD) Systems (nDS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126804413","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}
