But, to a certain extend, there is a setback in development due to presence of caster wheels. Hence, this paper proposes a casterless wheelchair and its control on a straight line path. That is, straight line driving of two wheel power assist wheelchair robot was proposed in this paper while keeping stability of wheelchair body itself. Balancing of wheelchair body is proposed to achieve by controlling the inverted pendulum mounted on the wheelchair. Control equations of the system are derived using Lagrange equation of motion. Two separate controllers are designed for two wheels. In addition to these two controllers, there is another controller for pendulum. Body controller is designed combining pendulum controller and wheel controller. Disturbance observer is used to cancel disturbance effects.

The passive antenna design is based on dividing the circuit into bulk feed line, micromachined line to bulk feed line transition and membrane supported micromachined antenna. Each region is modeled using full wave electromagnetic simulation software HFSS. In the active antenna, the two-port membrane supported micromachined antenna is connected in positive feedback path of an MMIC amplifier chip using bulk feed lines. The fabricated micromachined passive antenna element resonated at 34.2 GHz. This antenna exhibited a bandwidth of 1.4 GHz for VSWR<2.0. The measured 3-dB E-plane and H-plane beam widths are 65-70 degrees that agrees fairly well with the simulated results. The initial active antenna oscillated at 35.64 GHz with 47.2 dBm power and showed a clean spectrum.","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876624","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}

Very often even in a printed text, adjacent characters tend to touch or connect. This makes it a problem in performing proper character isolation, hence difficult in segmenting the digit strings in order to recognize its individual characters. We, in our study have developed an algorithm, which provides a solution based on the analysis of the foreground pixel distribution to segment, connected digit string pairs. In the segmentation stage, the junction based splitting technique decides complete segments of the connected digit strings. Use of fuzzy characteristic values at the merging of the complete segments isolates the major segments (merged complete segments) from the minor segments. In this work, it was found that the unwanted connection resides within the minor segments of the connected character skeleton. At the character isolation stage, all major segments are combined with each of minor segments to generate set of different connection sketches. In order to recognize individual characters of the connection string, these sketches are formulated into a new input character image, which then can be used as an input for a character recognition system","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131460059","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 this paper a novel test pattern generator (TPG) is proposed which is more suitable for built in self test (BIST) architecture, used for testing of VLSI circuits. The objective of the BIST is to reduce power consumption during testing of VLSI circuits. In CMOS devices 80% of power consumption is due to switching activity occurred during operation. The proposed TPG is based on read only memory (ROM) which is carefully designed to store the test vectors with minimum area over the conventional ROM. This reduces the number of CMOS transistors significantly when compared to that of LFSR/counter TPG. The proposed TPG is more suitable for deterministic pattern testing and the fault coverage is improved over the LFSR. Low power reordered test patterns also can also be stored in the same order to reduce the test power in circuit under test (CUT). The TPG is designed and implemented for benchmark circuits ISCAS 85 and 89. Experimental results shows that a considerable reduction in number of CMOS devices and test power is achieved over the LFSR-TPG","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"472 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131988811","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}
