Abstract: One or more features of a friction ridge signature of a subject may be identified based on information representing a three-dimensional topography of friction ridges of the subject. Information representing the three-dimensional topography of the friction ridges of the subject may be received. One or more level-three features of the friction ridge signature of the subject may be identified based on the information representing the three-dimensional topography of the friction ridges of the subject. The one or more level-three features may include one or more topographical ridge peaks, topographical ridge notches, topographical ridge passes, pores, and/or other information.

Abstract: A total internal reflection based imaging system may include a light transmitting member having an imaging surface. A pressure sensitive membrane may be arranged on the imaging surface. The pressure sensitive membrane may include a top surface, a bottom surface, and an elastic deformable film forming at least a portion of the top surface. The imaging system may include a textured surface disposed between the pressure sensitive membrane and the imaging surface. An application of pressure on the top surface may deform the deformable film to reduce a distance between the deformable film and the imaging surface. A light source may be configured to emit a light towards the imaging surface such that reduced total internal reflection of the light occurs where the bottom surface of the pressure sensitive membrane contacts the imaging surface. A sensor may be configured to capture the light reflected from the imaging surface.

Abstract: A representation of variations in elevation of friction ridges in a friction ridge pattern of a subject may be generated. A sequence of images captured over a time period may be obtained. Individual images in the sequence of images may indicate areas of engagement between an imaging surface and the friction ridge pattern of the subject when the individual images are captured. Temporal information may be obtained for the individual images. The temporal information for the individual images may be used to aggregate the individual images in the sequence of images into an aggregated representation of the friction ridge pattern. The aggregation may be accomplished such that the aggregated representation depicts the areas of engagement of the friction ridge pattern with the imaging surface at different elevations of the friction ridge pattern.

Abstract: A monitoring system in a medical facility provides an identification device to a patient and a data acquisition device to a health-care worker. The identification device wirelessly emits a first signal that identifies the patient and the data acquisition device emits a second signal. A determination is made in response to the first signal and the second signal, whether the health-care worker is absent from being near the patient. For example, absence of the health-care worker is determined when a data reader receives only the first signal. This system detects when a patient requiring continuous observation is not in the presence of a health-care worker. In that case, an alarm message is sent to supervisory personnel.

Abstract: A medical patient is issued an identification device that emits a first wireless signal providing a patient identification. A plurality of data collectors are placed at different locations in a medical facility to receive the first wireless signal when the patient is nearby. A separate patient event record is generated whenever one of the data collectors receives the first wireless signal and each such record contains the patient identification, time of receipt, and identification of the receiving data collector. The plurality of patient event records are analyzed to derive a report about activity of the patient within the medical facility. For example the report may indicate bathroom activity of the patient or how far and often the patient walked around the medical facility. The reports are useful to monitor and evaluate the patient's medical condition, recovery and security.

Abstract: A user enters data about a resource into a computer using a method wherein the user selects a data field in which the data is to be entered. In response to that selection, the computer reviews previously stored records related to the resource to find instances of data contained in the data field. Those instances then are displayed to the user, who selects of one of the instances as a value to be entered into the data field. Thus the user is provided with a list of previous values that are contained in the selected data field for the resource, which list facilitates locating and entering information in new records for this resource.

Abstract: The amount of time actually worked by an employee and the amounts of time that the employee is scheduled to work in the future are analyzed to project whether the employee will be entitled to overtime compensation. That analysis is based on rules which define when overtime compensation accrues. When overtime is projected to occur, a message indicating that projection is automatically sent to supervisory personnel, who can respond by accepting the projected amount of overtime or by changing the employee's work schedule to avoid the overtime occurring.
