摘要:
A biometric verification system for controlling access is provided that does not rely on a non-biometric discriminator, such as a PIN or magnetic card, to convert a one-to-many verification task to a one-to-one verification task. The system enrolls authorized users by obtaining digitized fingerprint templates from them and storing them in a database. Video cameras and fingerprint sensors are provided for use in authenticating persons seeking access. Software compares a digital representation of a captured human facial image with stored facial images in a database of facial images, generating a match confidence therefrom and rank-ordering the database from highest to lowest match confidence. The software then compares captured human fingerprints with stored fingerprint templates associated with the rank-ordered database to verify the identity of the person and provide an output signal indicative of recognition.

An articulated and animated toy capable of recognizing human users and interacting therewith includes a computer-based device storing encoded first human fingerprint data, a fingerprint sensor for acquirin data representative of a second human fingerprint, and software for fingerprint verification. The apparatus can further include software for recognizing speech, generating speech and controlling animation of the articulated toy. In addition, the toy is capable of learning and storing information pertaining to each of said human users such as name, age, sex, favorite color, etc., and to interact with each of said human users on an individual basis, providing entertainment tailored specifically to each of said human users.
摘要:
An automated access control apparatus and method. Identification data is compared with stored data to determine if a person should be granted access to an area. If granted access, the person is prompted to indicate a number of guests desiring access. As the person and the guests pass through entrance, the persons are counted and proper personnel is notified if an unauthorized number of persons enters the area. Unauthorized entries are recorded as image data that can be played in real time or at a later time for review. Guest entry is logged for billing purposes.

摘要:
An automated screening tool for the exclusion of deep venous thrombosis generally comprises a sensor array for gathering thermal data from the lower limbs of a patient suspected of DVT; a processor for automated analysis of the gathered data; and a display device for reporting the exclusion or non-exclusion of DVT. In the preferred embodiment of the present invention, a microprocessor based system is utilized to control the gathering of thermal data and, thereafter, the reporting of the gathered data to the processor. According to the preferred method for use of the present invention, the gathered thermal data is utilized, alone or in combination with other indicators, as a factor for exclusion of DVT based upon an implemented algorithm. According to the preferred embodiment of the present invention, a neural network or genetic algorithm is implemented within the processor in order to make an entirely objective determination relative the presence of DVT. This feature makes the present invention particularly adapted to multiple risk factor analysis, wherein factors such as calf circumference; positive Homan sign; colorimetry reading of the limbs; recent surgery or trauma; history of DVT, phlebitic syndrome or venous insufficiency; or presently uncannulated veins may be considered along with thermographic data.

An articulated and animated toy capable of recognizing human users and interacting therewith which includes a computer-based device having stored thereon encoded first human fingerprint data, a fingerprint sensor for acquiring data representative of a second human fingerprint, and software resident within said computer-based device for fingerprint verification, which includes minutiae analysis, neural networks, or another equivalent algorithm for comparing said first human fingerprint data with said second human fingerprint data and producing an output signal therefrom for use in identifying said human users. The apparatus can further include software for recognizing speech, generating speech and controlling animation of the articulated toy. In addition, said computer-based device is capable of learning and storing information pertaining to each of said human users such as name, age, sex, favorite color, etc., and to interact with each of said human users on an individual basis, providing entertainment tailored specifically to each of said human users. In addition, the apparatus can control access to the Internet via integrated web browser software and thus provide protection, especially for young children, from inappropriate web site content.
摘要:
A system and method for analyzing tissue healing may include capturing an image including a tissue site. A clinician may be enabled to define multiple regions of the image of the tissue site, where at least two of the regions of the image define tissue types at different stages of tissue healing. An area may be calculated of each of the at least two regions of the image defining tissue type at different stages of tissue healing. The calculated areas may be displayed to a clinician. In one embodiment, an image color adjustment may be determined by adjusting the image of the reference color marker to the predetermined color. The image of the tissue site may be normalized by applying the image color adjustment to generate a normalized image.

A laparoscopy simulator includes two rods and an orientation sensor that determines the orientation of the rods. An optical sensor is used to determine measurements of each rod based on the rotation of the rod around a central axis of the rod and a sliding of the rod along the central axis. An accelerometer is used to determine additional measurements of each rod based on a rotation of the rod around two additional rotation axes of the simulator. The measurements are used to determine the overall orientation of the rods.
