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.

Security-enhanced computer systems and methods

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 then 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. A central digital signal processor with a similar current transformer connected to the power lines detects, demodulates and decodes the measurements data for the use of overall battery array control and maintenance.

Accumulator battery monitoring over power circuit

A system for verification of video clips, including a media player connected via a network to a media server, the media player receives a compressed video clip from the media server; a display monitor powered connected to a video player for receiving a decompressed video clip; a current sensor coupled the display monitor for measuring current consumption of the display monitor while the video clip is played; a DSP module for receiving current consumption measurement and generating a fingerprint of the clip; network storage storing log files; local storage coupled to the media player and storing known fingerprints reflecting current consumption corresponding to video clips. The DSP module sends the fingerprint to the media server; the media server stores the fingerprint in a log file on the network storage for verification of subsequent reproduction of the clip on the display monitor.

Method and system for verification of video signal validity

Systems and methods for controlling access to peripherals of a computer system by software applications

A network of surveillance digital video cameras is provided. Each camera records video data and provides the video recordings to other networked cameras as well as to a central video storage. The instantly created plurality of copies of surveillance video recordings adds a great degree of difficulty for attempts to eliminate all of the individual camera's recordings during a security breach. Each networked camera is equipped with its own integrated storage device capable of holding several hours of recorded video footage. The networked cameras can exchange copies video data and store it locally on integrated storages.

Tamper-resistant video surveillance network

An apparatus and method includes a solar panel. A power bus is coupled to the solar panel, and supports transmission of AC communication signals. The power bus includes a high current power wire. A current transformer is coupled to the power bus adjacent the solar panel. A capacitor, coupled to the power bus, is connected in parallel with the solar panel, and connected between the solar panel and the current transformer.

Method and system for current-mode power line communications

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.

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.
