Real-time detection of moving objects involves memorisation of features in the template image and their comparison with those in the test image. At high sampling rates, such techniques face the problems of high algorithmic complexity and component delays. We present a new resistive switching based threshold logic cell which encodes the pixels of a template image. The cell comprises a voltage divider circuit that programs the resistances of the memristors arranged in a single node threshold logic network and the output is encoded as a binary value using a CMOS inverter gate. When a test image is applied to the templateprogrammed cell, a mismatch in the respective pixels is seen as a change in the output voltage of the cell. The proposed cell when compared with CMOS equivalent implementation shows improved performance in area, leakage power, power dissipation and delay.

We report a resistance based threshold logic family useful for mimicking brain like large variable logic functions in VLSI. A universal Boolean logic cell based on an analog resistive divider and threshold logic circuit is presented. The resistive divider is implemented using memristors and provides output voltage as a summation of weighted product of input voltages. The output of resistive divider is converted into a binary value by a threshold operation implemented by CMOS inverter and/or Opamp. An universal cell structure is presented to decrease the overall implementation complexity and number of components. When the number of input variables become very high, the proposed cell offers advantages of smaller area and design simplicity in comparison with CMOS based logic circuits.Comment: Memristors, Brain inspired logic circuits.

Loss of any organ of a body is a traumatising event as it creates functional, esthetics and psychological disharmony in an individual's life. An ocular defect can be a congenital anomaly or an acquired defect. Rehabilitation of such defect with customized well fitting prosthesis that restores the shape of associated anatomical structures and volume of the socket, not only require an artistic skill but also technical knowledge as every case is unique on its own. The main objective of this article is to describe innovative yet simple technique using NAES ruler for iris selection and fixation of gaze yielding results with utmost patient satisfaction and acceptance.
