  • Patent number: 7184582
    Abstract: A method, system and computer readable medium for an intelligent search display into which an automated computerized image analysis has been incorporated. Upon viewing an unknown mammographic case, the display shows both the computer classification output as well as images of lesions with known diagnoses (e.g., malignant vs. benign) and similar computer-extracted features. The similarity index used in the search can be chosen by the radiologist to be based on a single feature, multiple features, or on the computer estimate of the likelihood of malignancy. Specifically the system includes the calculation of features of images in a known database, calculation of features of an unknown case, calculation of a similarity index, display of the known cases along the probability distribution curves at which the unknown case exists.

  • Publication number: 20060254867
    Abstract: A wheel supporter with a brake includes a rotary shaft, a base, a pedal, a brake plate and a return spring. The base has a covering member, a shaft support member, and an eccentric support member. The eccentric support member has an upper stage provided with a sidewise round post, and the brake plate has a front projection, two wings provided in a rear portion, and an upper recess formed to mount on the round post. If the pedal is stepped down, the brake plate is pressed down to force the wings contact the wheel to produce frictional resistance against the wheel, and at the same time the front projection of the brake plate fits in one of the gaps formed by every two teeth of a disc gear fixed with a lower end of the rotary shaft to stop the rotary shaft immovable. The brake plate is easily combined with the wheel supporter, and applicable to various types of wheels.

  • Publication number: 20050234570
    Abstract: A method for computer-assisted interpretation of medical images that factor in characteristics of an individual performing the interpretation. The method automatically determines and/or incorporates prevalence-based computer analysis based on an estimated likelihood of a pathological state, e.g., a malignancy. A system implementing the method includes the calculation of features or other characteristics of images in a known database, calculation of features of an unknown case, calculation of the probability (or likelihood) of disease state, calculation of the modified computer output that includes the internal prevalence (or internal decision-making process) of the user (or group of users), and output of the result.

  • Publication number: 20050171879
    Abstract: An interactive counter service system for banks and similar finance organizations mainly includes a touch-screen module, a counter-terminal module, and network communicating equipment. The touch-screen module is mounted at counters of the banks to serve as an interface via which a customer may select one or more desired transactions provided by the bank and input required data via a magnetic strip reader or a card reader of the touch-screen module. The counter-terminal module enables a counter clerk to synchronously receive and process the data input by the customer and provide on-line business consultation to help the customer to complete the selected transaction. The interactive counter service system effectively improves the interactive relation between the customer and the bank and thereby upgrades the service quality of the bank.
