A patient fluid discharge monitoring method and apparatus includes at least one article configured to be worn by a patient, the article having absorbent material and a RF tag received adjacent the absorbent material. The RF tag is excited with an excitation signal and the response of the RF tag to the excitation signal is detected. The detected response of the RF tag is compared to a predetermined response. The RF tag has a first detected response when the absorbent material has no fluid therein and a second detected response when the absorbent material has fluid therein.

A system for training or aiding an impaired individual to perform a series of tasks at spaced work sites comprises a mobile device for being worn or carried by the individual. The mobile device comprises circuits and devices for detecting the position of the mobile device relative to the spaced work sites. It further comprises a programmed computer having a memory for storing a data structure associating each task with the ordinal number of the task, a task description, the site at which the task is to be performed, a flag or pointer indicative of whether a task has been performed and messages containing cues and/or instructions for each task. The programmed computer also comprises a memory and processor for storing and executing a program which based upon the task flag or pointer and the location of the mobile module for cueing and/or instructing the individual to perform a task at a site.

A system for computer vision comprises a source of digitized video signals and a frame encoder circuit connected to the source of digitized video signals. The frame encoder encodes threshold crossing events at at least two threshold levels and stores encoded data for a two-dimensional area within the frame in a cache memory. The threshold levels are programmable. A computer is in communication with the encoder circuit at least via its data bus and address bus for programming the threshold levels and controlling the encoder and accessing the data in said cache memory. The computer has an associated main memory with a stored task for reading the cache memory and interactively controlling the frame encoder circuit and interpreting the data gathered thereby. Data is encoded by event type and pixel address wherein the event type is indicative of threshold crossed and direction of crossing. The task stored in main memory has an algorithm for continuously changing the threshold levels and analyzing the data in successive frames until the desired threshold levels are achieved.

A system for computer vision is based upon an image sensor that maps an image to memory cells in association with a computer. An object orientation and position patch is attached to an object to be observed comprising a planar substantially coplanar and non-collinear reflective locations positioned upon the patch and a reflector having the reflective properties of the surface of a regular curved surface intersecting the planar surface. The computer has a task stored in main memory for detecting and quantifying a change in orientation and position of the object from the location of the image of the orientation and position patch.

A homing system for directing the user to one of a plurality of objects and/or locations comprises a plurality of remote modules and a mobile module. The remote modules transmit an uncoded nondirectional response signal after receiving a coded request signal. The mobile module at spaced intervals transmits coded nondirectional request signals. The mobile module generates internal representation of the distance between the receiving means and the selected module from the time measured between the transmission of the request signal and the receipt of the response signal.

A patient position monitor having an inclinometer and a microprocessor connected to the output of the inclinometer. The inclinometer is a body axis orientation sensor having a light impermeable capsule including a cylindrical body. The longitudinal axis of the cylindrical body is parallel to the patient's body axis. The cylindrical body includes a first end portion having a circuit board with a radial array of sequentially illuminated LEDs. A light sensor is mounted on a second end portion of the cylindrical body. A light impermeable sphere disposed in the capsule between the array of LEDs and the light sensor is sized to block light emitted from a portion of the LEDs. The detection of light from the unblocked LEDs is indicative of the position of the sphere and of the orientation of the patient's body axis relative to gravity.

Medical device or instrument for diagnosing pressure ulcers using optical reflectance spectroscopy. The device may comprise a tip and a controller. The tip is pressed against the skin of the patient and collects the optical reflectance data. The controller processes the data to determine whether there exists a pressure ulcer and, if there is one, its depth. The tip may also include a pressure sensor for sensing the pressure at which the tip is applied to the patient's skin.
