Abstract: A caregiver assistance system helps caregivers manage the care of patients and the beds that support the patients. The system monitors tasks associated with the patients, such as caregiver rounding tasks, bed sore assessments, and/or fall risk assessments, and forwards completed tasks to an EMR server. The system includes one or more mobile electronic devices that are used to display data about beds and/or the patients assigned to them, and/or to receive data about the beds and/or the patients assigned to them. The system automatically associates data received from the mobile electronic device with a particular patient and/or a particular bed without requiring the user to manually identify the patient or the bed. The data may relate to images of skin conditions of the patient, service requests for the beds, and/or other data. The system may automatically forward service requests to a separate service server that communicates with service personnel.

Abstract: A radiance source includes a housing having an interior wall, wherein at least a spherical portion of the interior wall of the housing is spherical, an interior volume, and an exit port. A light source is disposed within the interior volume of the housing. A calibration structure blocks and reflects a light ray that would otherwise travel directly from the light source to the exit port without reflecting from the interior wall. The calibration structure has a calibration body having a curved back surface facing the light source and a curved front surface facing the exit port. There is an optically diffuse, lambertian reflecting surface on at least the spherical portion of the interior wall of the housing, the back surface of the calibration body, and the front surface of the calibration body.
