Packets passing between the other virtual machines pass through the driver domain, are hooked, and are inspected by inspection agent to determine if they are malicious or not. Malicious packets are blocked. The driver domain may also utilize a PCI driver of the privileged domain for access to the network interface card. Platforms with or without pass-through mode may be used.

Abstract: Anti-pharming techniques in wireless computer networks at pre-IP state are disclosed. A user computer connecting to a wireless computer network may include an anti-pharming module configured to monitor data communications to and from a wireless access point of the wireless computer network. The anti-pharming module may be configured to determine if data communication going in a direction from the wireless access point to the user computer originated from a wireless station rather than a server configured to dynamically provide network addresses to computers connecting to the wireless computer network. The wireless station may be deemed a malicious computer perpetrating a pharming attack when it originated the data communication and is responding to a request to obtain network address previously sent by the user computer.

Abstract: A scan client in a subnet of an intranet may be designated as a root agent to provide subnet information to a scan server in the intranet. The subnet information may include addresses of computers belonging to the subnet. The scan server may use subnet information collected from various root agents to build a map of the intranet. The intranet map may be forwarded from the scan server to the root agents, which in turn provide the intranet map to scan clients in their respective subnets. The root agents may also receive antivirus modules from the scan server for distribution to scan clients. A scan client may look for computers indicated in the intranet map to determine whether or not it is connected to the intranet.

Abstract: To protect a user computer from eavesdroppers, a secure communication connection is created through a computer network. The secure communication connection may be created even when the user computer communicates with a web server computer that does not support secure communication connections. The secure communication connection may be to a protection server computer. Another communication connection may be formed between the protection server computer and the web server computer to allow the user computer to transfer data to the web server computer by way of the protection server computer. The creation of the secure communication connection may be by user request or automatic upon detection of protected address or data.

Abstract: A high-speed tire repair tool includes a locating unit having an outer tube and a locating bar; a buffer element having a head and an inner tube connected to the head and received in the outer tube with the locating bar fixed to the inner tube at a predetermined position; a hollow pipe mounted in the outer tube, the inner tube, and the head; and a hole plugging assembly mounted to the head and connected to the hollow pipe, and having an abrasive element and a plugging strip.

Abstract: The present invention is a speech encoding technique useful in low data rate speech. Spoken input is analyzed to determine its basic phonological linguistic units and syllables. The pitch track for each syllable is compared with each of a predetermined set of pitch patterns. A pitch pattern forming the best match to the actual pitch track is selected for each syllable. Phonological linguistic unit indicia and pitch pattern indicia are transmitted to a speech synthesis apparatus. This synthesis apparatus matches the pitch pattern indicia to syllable groupings of the phonological linguistic unit indicia. During speech synthesis, sounds are produced corresponding to the phonological linguistic unit indicia with their primary pitch controlled by the pitch pattern indicia of the corresponding syllable. This achieves some measure of approximation to the primary pitch of the original spoken input at a low data rate.

Abstract: Speech is analyzed for phonological linguistic units (phonemes or allophones), along with their duration pattern and pitch pattern contour as a group or string of a syllable. The patterns are encoded as the best-match pattern in a set of prestored standard patterns. This data is transmitted to a synthesizer to help in the intonation reconstruction of speech.

Abstract: An electronic apparatus in which the operator inputs both the textual material and a sequence of pitches which upon synthesization simulates singing qualities. The operator inputs a textual material, typically through a keyboard arrangement, and also a sequence of pitches as the tune of the desired song. The text is broken into syllable components which are matched to each note of the tune. The syllables are used to generate control parameters for the synthesizer from their allophonic components. The invention allows the entry of text and a pitch sequence so as to simulate electronically the singing of a tune.

Abstract: A text-to-speech synthesis system receives digital code representative of characters from a local or remote source, and converts those character codes into speech. A set of allophone rules is contained in a memory and each incoming character set is matched with the proper character set to describe the sound of that particular character set. A microcontroller is dedicated to the comparison procedure which provides allophonic code when a match is made. The allophonic code is provided to a speech producing system which has a system microcontroller for controlling the retrieval, from a read-only memory, of digital signals representative of the individual allophone parameters. The addresses at which such allophone parameters are located are directly related to the allophonic code. A dedicated microcontroller concatenates the digital signals representative of the allophone parameters, including code indicating stress and intonation patterns for the allophones.

Abstract: Method and apparatus for converting voice characteristics of synthesized speech from a single applied source of synthesized speech in a manner obtaining modified voice characteristics pertaining to the apparent age and/or sex of the speaker. The apparatus is capable of altering the voice characteristics of synthesized speech to obtain modified voice sounds simulating child-like, teenage, adult, aged and sexual preference characteristics by control of vocal track parameters including pitch period, vocal tract model, and speech data rate. A source of synthesized speech having a predetermined pitch period, a predetermined vocal tract model, and a predetermined speech rate is separated into the respective speech parameters. The values of pitch, the speech data frame length, and the speech data rate are then varied in a preselected manner to modify the voice characteristics of the synthesized speech from the source thereof.

Abstract: An electronic apparatus for translation from a host language to a non-host language in which the individual word is evaluated as to its contextual meaning. The sequence of words, typically a sentence, within the host language, which is communicated to the electronic apparatus is translated, through a recognition device into a series of recognized words. These recognized words are further refined through analysis of their contextual meaning within the sequence (sentence) so as to differentiate between words of similar pronunciation and between homonyms. The present invention permits the direct entry, from voice, to a translator to a foreign language or alternatively to control language for use with an electronic or electromechanical apparatus.

Abstract: A formant tracker for receiving an analog speech signal and generating indicia representative of the formant. A pitch tracker determines the fundamental frequency of the analog speech input. The fundamental frequency is used to control a sinusoidal oscillator in the generation of a sinusoidal signal which when combined with the analog speech input generates a convolution over the chosen formant frequency. The process is repeated for each integer multiple of the fundamental frequency, thereby changing the sinusoidal oscillator. The optimal integer multiple is chosen which generates the formant identification. The optimal integer is also used to generate an appropriate bandwidth. Three formant frequency ranges are used to define human speech. The optimal integers for the other two formant identifications and the appropriate bandwidths are similarly determined. The three optimal integer values are combined with the fundamental frequency to get the three formant values and their associated bandwidths.

Abstract: An electronic, speech producing system receives allophonic codes and produces speech-like sounds corresponding to these codes, through a loud speaker. A micro-controller controls the retrieval, from a read-only memory, of digital signals representative of individual allophone parameters. The addresses at which such allophone parameters are located are directly related to the allophonic code. A dedicated microcontroller concatenates the digital signals representative of the allophone parameters, including code indicating stress and intonation patterns for the allophones. The allophones are divided into a plurality of frames with one digital position indicating whether the frame is the last frame in the allophone, in which event an extra frame is introduced to provide smoothing between allophones when no stop is present and when the present allophone is voiced and the subsequent allophone is voiced, or when the present allophone is unvoiced and the subsequent allophone is unvoiced.
