Methods and systems are provided for a proactive approach for computer forensic investigations. The invention allows organizations anticipating the need for forensic analysis to prepare in advance. Forensic signatures are created including a digital fingerprint and other information associated with a file. In one aspect, informational signatures are created, which may assist in determining what information is included in a file. In another aspect, the digital fingerprint may represent contents of the file and is resistant to minor modification of the file. In another aspect, fingerprints can be compared in parallel on different computers.

A beam profile measurement detector is a tool to efficiently verify dose distributions created with active methods of a clinical proton beam delivery. A Multi-Pad Ionization Chamber (MPIC) has 128 ionization chambers arranged in one plane and measure lateral profiles in fields up to 38 cm in diameter. The MPIC pads have a 5 mm pitch for fields up to 20 cm in diameter and a 7 mm pitch for larger fields, providing an accuracy of field size determination of about 0.5 mm. The Multi-Layer Ionization Chamber (MLIC) detector contains 122 small-volume ionization chambers stacked at a 1.82 mm step (water-equivalent) for depth-dose profile measurements. The MLIC detector can measure profiles up to 20 cm in depth, and determine the 80% distal dose fall-off with about 0.1 mm precision. Both detectors can be connected to the same set of electronics modules, which form the detectors' data acquisition system. The detectors operate in proton fields produced with active methods of beam delivery such as uniform scanning and energy stacking. The MPIC and MLIC detectors can be used for dosimetric characterization of clinical proton fields.

The invention relates to an ultrasonic-control electric rice cooker, belonging to the technical field of household electric appliances. In order to overcome the defect that the working mode of the electric rice cooker in the prior art must depend on measuring the change of the temperature of an inner pot in a mechanical contact way and monitoring the change of vocal prints of the inner pot to obtain temperature change as a control basis, the ultrasonic-control electric rice cooker takes the following measures that an ultrasonic generator and an ultrasonic receiver are installed on the electric rice cooker, and the ultrasonic receiver is connected with a vocal print recognition circuit. Physical information such as the internal temperature and the water condition of the inner pot of the electric rice cooker is obtained by actively transmitting ultrasonic waves towards the inner pot of the electric rice cooker and by adopting an active method of analyzing ultrasonic vocal print electric signals received by the ultrasonic receiver. The benefits of taking the measures are that the ultrasonic waves at the most sensitive frequency band can be selected according to the characteristics of the inner pot of the electric rice cooker, more, clearer, more accurate and more reliable physical information such as the internal temperature and the water change of the inner pot of the electric rice cooker can be obtained, and a reliable basis is provided for a control circuit.
