Abstract: A system and method are provided for determining eye closure state of the eye of a subject. The system includes a video imaging camera oriented to generate images of an eye of a subject and a video processor for processing the images generated with the video imaging camera. The video processor is configured to detect an eye in the video images and determine whether the images of the eye are noisy. The video processor processes geometrical and statistical shape of the eye in the images if the eye is not noisy, and processes changes in the size of the eye over time if the images are noisy. The processor further determines eye closure state based on a ratio of horizontal to vertical dimensions.

Abstract: A system for measuring the awareness of a subject including an imaging device adapted to acquire data representative of an image of the subject, and an awareness processor connected to the imaging device, wherein the awareness processor is adapted to classify the awareness of the subject according to the position of the subject.

Abstract: A system and method are provided for detecting one or both eyes of the driver of a vehicle. The system includes a video imaging camera oriented to generate images of the driver's face. The system also includes a video processor for processing the images generated with the video imaging camera. Filters are applied to each of potential eye candidates to determine which candidates represent an eye, weighted values are assigned to the filtered eye candidates, and an eye is detected based on the weighting of each eye candidate. According to one aspect, different size patches of potential eye candidates are processed and compared to models.

Abstract: A system and method of injecting audio content into a radio system is provided. The method includes the steps of receiving in a radio receiver a first RF signal from an antenna and processing the signal at a select frequency within a radio frequency band. The method also includes the step of providing audio content from an auxiliary device. The method also includes the step of modulating the audio content from the auxiliary device and replicating the modulated signal to generate a replicated RF signal at the multiple frequencies within the radio frequency band. The method further includes the step of injecting the replicated RF signal into the radio receiver.

Abstract: The present invention is directed to a system and method of navigating audio compact discs utilizing voice commands. The system includes both in-vehicle components and off-vehicle components. In the vehicle are the compact disc player and a processor associated with the player and an optional local database of data relating to compact discs, such as the song titles, track numbers, etc. Off the vehicle is at least one remotely located database of compact disc information which is searched by the processor via a link, such as a wireless network or the Internet. The user would insert a compact disc and describe the desired song, with the processor searching the databases for data relating to the compact disc and a matching description of the song to be played. When a match is found, the song is played and if no match is found, then the system defaults to conventional navigation controls.

Abstract: An improved application processing system (18A, 18B, 18C, 18D, 18E) which utilizes both on-board components and off-board components connected via wireless data transfer devices (62, 64). On-board the vehicle is a user interface, or a microphone (22), which receives data in the form of human speech from the user (20), and components for digitization (56) and feature extraction (58) of the data with the data then being sent to an off-board processing system (66), which may include a speech recognition system (72) and a voice-enabled program application (74). After the data has been processed by the off-board system (66), the data is retransmitted to the on-board system, where the processed data (76) is converted from text to speech (78), reconstructed as speech (79), or displayed. The display or speech is then distributed to the drive or occupants by a radio (80), handheld device, or a display unit (84).

Abstract: An alert system 12 and a method for operating the same including a condition information receiver 28, which receives condition data 14 and generates a condition information signal 30, is provided. The condition alert system 12 also includes a positioning system receiver 27 receiving position data 17 and generating a position signal 29 in response to the position data 17. A system controller 31 is electrically coupled to the condition information receiver 28, the positioning system receiver 27, and an indicator 23. The system controller 31 indicates a condition alert signal via the indicator 23 in response to the condition information signal 30 and the position signal 29.

Abstract: Voice access is provided to information stored in a dynamic database located within an external data source. A communication link is provided between the external data source and a voice capable device, which includes a speech recognition application and a grammar generation application. Text data is then retrieved from the dynamic database located within the external data source. The text data is then organized into new grammars, which are then converted into phonetic transcriptions. The new and existing grammars are then available to the speech recognition application to facilitate speech recognition.
