An intrusion detection system and methods thereof are provided. In exemplary embodiments, the system may comprise an upper scanner adapted to create a first detection layer; a lower scanner adapted to create a second detection layer, the second detection layer overlapping the first detection layer; signal lighting for producing a visual signal; at least one server adapted analyze data received from the upper scanner and the lower scanner to determine if an object is in the path of the vehicle; and wherein the at least one server is adapted to activate the signal lighting when it is determined by the server that an object is in the path of the vehicle.

Intrusion detection system and methods thereof

One embodiment includes hardware-based cybersecurity devices that create a physical barrier ('hardware security barrier') between a computer's (or other device's) processor and a public or private network. Hardware security barriers typically use immutable hardware in accomplishing cybersecurity activities including generating and distributing cryptographically secure numbers, encryption, decryption, source authentication, and packet integrity verification. This hardware security barrier protects against remote threats and guarantees that all exported and received data are strongly encrypted. A hardware security barrier can be included in any computing or networking device that contains a network interface. One embodiment of a hardware security barrier is implemented as part of a network interface, such as, but not limited to being part of a network interface controller, or as a standalone unit between a communications interface of a host system and a connection to a network.

Secure network communications using hardware security barriers

A Delay-tolerant Asynchronous Interface (DANI) is typically used to make the clock domains for reusable silicon intellectual property (IP) cores completely independent of each other. In fact, a DANI-wrapped IP core usually appears to its environment as if it were clockless. This property is necessary to address the variability in data transmission-time between source and destination. This variability is a result of increased lack of predictability in today's leading-edge manufacturing processes. A DANI wrapper can be applied to the IP core that is the source of data to be transmitted or it can be applied to the IP core that is the destination of that data. The transmission time over the route between source and destination may vary more than a single clock period.

A system for verifying the authenticity of data contained in a magnetic medium using the remanent noise characteristics of the magnetic medium. In one embodiment, the invention includes a sensing unit configured to generate a signal indicative of the sensed magnetic field and an amplifier. The amplifier is in communication with the sensing unit, is configured to amplify signals having amplitudes less than a threshold by at least a first factor and configured to amplify signals having amplitudes greater than the threshold by at most a second factor. The first factor is greater than the second factor. The invention also includes an analog-to-digital converter (ADC) in communication with the amplifier and configured to digitize the analog signal, a filter in communication with the ADC configured to attenuate the portion of the digitized signal indicative of the stored data, a data extraction unit in communication with the ADC and the filter, which is configured to measure bit duration and peak location and an authentication extraction unit in communication with the filter and the data extraction unit, which is configured to extract a set of scaled samples representative of the remanent noise characteristic.

Method and apparatus for authenticating a magnetic fingerprint signal using compressive amplification

Disclosed are, inter alia, instantaneously restartable clocks and their use. For example, instantaneously restartable clocks can be used to receive data from another independently clocked subsystem in a manner that removes the possibility of metastability errors. A restartable clocking signal generator, relying on oscillating signals typically generated by a continuous oscillating source, is used to generate a restartable clocking signal which can be asynchronously restarted in response to one or more control signals. In one implementation, an apparatus includes multiple independently clocked subsystems and a clockless sequencing network, with the clockless sequencing network being used to initiate the start of a restartable clock in order to reliably receive and process data between the independently clocked subsystems.

A system for verifying the authenticity of data contained in a magnetic medium using the remanent noise characteristics of the magnetic medium. One embodiment of the invention includes an over-sampled modulator and at least one channel in communication with an output of the over-sampled modulator. The at least one channel is configured to filter the output of the over-sampled modulator and the at least one channel is configured to vary the bandwidth of the filter applied to the output of the over-sampled modulator in response to variations in the bandwidth of the signal generated by the sensing unit.

A method and apparatus is disclosed for determining the remanent noise in a magnetic medium by, for example, DC saturation of a region thereof and measurement of the remaining DC magnetization. A conventional magnetic recording transducer may be used to determine the remanent noise. Upon determination, the remanent noise may then be digitized and recorded on the same magnetic medium to thereby 'fingerprint' the magnetic medium. This 'fingerprint' may then be later used to verify and authenticate the magnetic medium as being an original. The magnetic medium may be of a type adapted to record information magnetically or, even more broadly, any magnetic surface or substance that can be sensed through its magnetic field. In such manner, any magnetic medium, or any object having an associated magnetic medium, may be 'fingerprinted' including credit cards, computer program diskettes, magneto-optic discs, videotapes, cassette tapes, bank checks, stock certificates, etc.
