Abstract: In general, the invention provides a computer architecture designed for enhanced data security. In embodiments, the architecture comprises two sub-systems, each with their own processing units and memories, and a defined set of interfaces that interconnect the two sub-systems and the external world. One sub-system is designed to provide a familiar environment for running computer applications. The other sub-system is designed to provide a secure bridge between the first sub-system and users via input and output devices.

Abstract: A method for verification of a video signal employs measurements of luminosity of video display monitors. A current consumption of the video display monitors is measured at a sampling rate. The measured current display consumption is used as a measure of the total luminosity of the display screen at the time of measurement. A special software module within a digital recording unit is used to calculate an aggregate luminosity of every recorded video frame. A central verification system generates subtle yet measurable changes in illumination of the surveyed scenes. The central verification system detects and analyses the correlated changes in display monitor's current consumption to verify that the assigned monitor is actually displaying its assigned scene. The software module produces an event notification along with a timestamp of the event whenever the frame luminosity changes between adjacent frames.

Abstract: The invention is in the field of monitoring and controlling of rechargeable battery arrays as used in telecommunications power plants and vehicles equipped with all-electrical or hybrid-electrical power train. The invention presents a method of embedding a microcontroller into each individual cell in the array, which executes measurements of cell voltage, temperature and optionally instantaneous current. These measurements are aimed to reflect the cell state-of-charge and its overall maintenance state, i.e. health or life expectancy. The measured data is thence transmitted over the same wires that conduct the electrical energy to and from the battery cells using a Rogowsky type coil (a.k.a. current transformer) to superimpose a high-frequency alternating-current modulated signal over any direct current flowing through the power wires.

Abstract: A method and system includes a solar panel. A power bus is coupled to the solar panel. The power bus supports transmission of AC communication signals. A slave node, coupled to the power bus, transmits information regarding solar panel performance. A master node, remotely coupled to the slave node over the power bus, receives the information regarding solar panel performance from the slave node.

Abstract: The present invention relates to process I/O controllers for semiconductor manufacturing to which a tool host can delegate data collection, monitoring and control tasks. In particular, it relates to process I/O controllers that can perform more than one of data collection, monitoring, control and response to commands from a tool host with statistically repeatable performance and precision. Embodiments described use prioritized real time operating systems to control of semiconductor manufacturing tools and data collection from tool associated with the sensors. Statistically repeatable responsiveness to selected commands and to sensor inputs during selected recipe steps effectively reduces jitter.
