In this paper, we describe The Digital Respiration Rate Meter, a device used to measure the rate of respiration. It consists of a transmitter section, receiver section and breathing setup. Transmitter section transmits IR waves which are cut by a displacement transducer in the breathing setup. This IR wave is sensed by the receiver section. The Controller section reads this and generates the count to be displayed. This is displayed on three seven-segment displays for read out.

Sustainability of old buildings is constantly challenged due to its non-compliance with energy saving practices. Old buildings which aim to deploy technologies to improve thermal comfort face some infrastructure constraints. The sustainability of such buildings is dependent on occupant's thermal comfort, low carbon emissions and reduced energy consumption. Such buildings face restraints in the way in which wired and wireless technologies could be used to implement sensing and control actions. Constraints include infrastructure limitations and space usage restrictions. This paper discusses retrofit solutions for old buildings for minimizing energy consumption and maximizing the occupant's comfort. The implementation of the retrofitted solution in an existing old building with minimal infrastructure change is elaborated. This includes implementation of thermal comfort based algorithm for zonal damper control, indoor air quality based window control and light sensor based blinds control. The sensing and control action is based on indigenous circuits communicating through ZigBee wireless protocol in Wireless SensorNetwork (WSN) of motes. A WingZ gateway runs the thermal comfort algorithm and acts as command centre for the WSN. The research aims to demonstrate the possibility of extending sustainability of existing old buildings by using energy conscious building automation solutions where large scale infrastructure change is not possible.

In this paper, an implementation of Dynamic Reconfigurable Touch Screen Keyboard (DRTSK) using a touch-screen panel and display are integrated in a development board is presented. An ARM920T based development kit (FriendlyARM) is programmed and implemented as a touch screen reconfigurable keyboard device. The FriendlyARM is interfaced with PC. The communication is through standard interfaces. The reconfigurable touch screen keyboard implemented on the hardware, tested under different operating systems and the functionality is validated.
