TRACKING SLOW VARYING FREQUENCY IN A NOISY ENVIRONMENT AND APPLICATIONS IN HEALTHCARE

Heart rate monitors are plagued by noisy sensor data, which makes it difficult for the monitors to output a consistently accurate heart rate reading.

The system intends to reinforce national security by installing safeguard on-board computer system on every commercial airplane, maximize customer confidence and satisfaction by providing scalable security/service management, communicate with FAA, FBI, or CIA systems by using new telecommunication technology, and Interact with Apollo, Saber and other airline legacy systems by providing individualized interfaces. The system also helps flight attendants to have better passenger services, and helps mechanics to have better aircraft maintenance.

Passive embedded interaction coding

A system and method for encoding a document image and finding a location based on that image are described. A document page is encoded into codes associated with various locations of the document page. The codes are assembled into a code book. Captured images may then be similarly encoded and searched against the codes in the codebook. One or more codes and associated locations may be returned, thereby providing one or more possible locations for the captured images.

Method and device for detecting rule optimization configuration

Use of an input black and white bitmap to generate emboldened anti-aliasing bitmap

A computer-implemented simulated emboldening mechanism for emboldening an input Black and White bitmap to generate an emboldened Anti-Aliasing bitmap. The simulated emboldening adjusts the intensity of the pixel in the direction of emboldening taking into account contextual information regarding surrounding pixels. Since the emboldening is not limited to a Black and White output bitmap, and since the emboldening takes such contextual information into account, legibility and readability of the resulting emboldened character is enhanced.

System and method for detecting a list in ink input

A system and method for detection of a list in ink input is provided. A detector is provided that may detect a list such as a bulleted or numbered list of items in ink input. A group of lines may first be selected as a candidate list. Indentation level clustering and bullet detection may then be performed to determine the structure of the list. Bullet detection may be performed by detecting bullet partners, which are pairs of lines at the same indentation level that may begin with bullet candidates with similar features. The features of the bullet candidates in a pair of lines may be used to determine the likelihood of whether the pair of lines may be bullet partners. Finally, the structure of the list may be determined, including the relationship among the list items.
