Abstract: A portable, autonomous electronic device consisting of a barcode scanner, an updatable nutrition facts database, user memory to store product records of products eaten, and an integral readout display is disclosed that will allow a user to scan barcodes on food items consumed and keep a cumulative total of calories and other nutrients. Prepared packaged foods may have their barcodes read directly, while foods that are used in cooking or preparing other foods may be referenced by scanning from a printed generic foods barcode list provided with the device. Serving sizes can be adjusted to accurately reflect the intake of given food items. Daily cumulative totals of calories and several other nutrients can be displayed as bar graphs, and the incremental increase that would result from consuring a scanned item can be displayed with reference to what has already been consumed.

Abstract: A method for the non-surgical treatment of soft tissue lesions includes placing a contact point near the lesion and causing the patient to move in a manner that produces a longitudinal sliding motion of soft tissues, e.g., nerves, ligaments, and muscles, beneath the contact point. Treatments are continued at sequential time intervals until the symptoms produced by the lesions are alleviated.

Abstract: A fetal health assessor and outcome predictor and monitoring system includes a system for automatically assessing fetal health and predicting fetal outcomes based on fetal and maternal data. The system includes a case-based reasoning processor for categorizing the fetus into one of a plurality of cases based on biographical data about the fetus and mother.

A computer processor converts the signals to a set of signal features. An assessor and predictor receives the processed signal features and assesses fetal health and predicts fetal outcome based on identified fuzzy relationships between fetal and maternal data and fetal outcomes.

Abstract: The present invention provides an improved method of administering a pharmaceutical composition, such as an anesthetic through the skin of a patient without the use of a sharp or needle. This method includes the step of irradiating the stratum corneum of a region of the skin of the patient using a laser. By a selection of parameters, the laser irradiates the surface of the skin precisely to a selectable depth, without causing clinically relevant damage to healthy proximal tissue. A pharmaceutical composition is then applied to the region of irradiation.

Abstract: An ambulatory recording system for medical and especially diagnostic purposes is described having synchronized communication between two processors. The recorder features two processors which are of differing architectures—the first processor being a real time processor which handles the sampling function, the second processor being a non real time processor which handles the operating system function. The invention further includes a protocol for communication between the two processors which permits the two processors to have synchronized and reliable communication.

Abstract: A fitness for duty (FFD) testing device and method for determining fitness for duty using a testing unit that is held in two hands by a human test subject. Two handles are provided for holding the unit which includes a video screen with an image of a moving shape on a surface. The position of the shape on the screen is determined by the orientation of the hand-held unit. Tilting the unit by the test subject results in the shape moving on the screen. The device computes a score which can be compared to historical results for the test subject, and to results from a larger population base. The FFD device may be programmed to present increasing levels of difficulty as test subject learning occurs, and can receive and provide data to external computing, printing, display, network, or storage devices.

Abstract: A method of monitoring Central Nervous Shunt performance by sampling non-invasive data from a patient with hydrocephalus condition. The sampled data is processed to produce a determination of probable shunt operation. Where the shunt may not operate properly, the processing produces a prediction of possible shunt malfunction. The processing includes a method to assess which of a set of possible malfunctions is the most likely. The processing can also be used to advise the user on how to remedy the problem diagnosed. The shunt performance rating can also be used to monitor shunt performance over time and process the time data to provide for a shunt operation status or observe the compatibility of a particular shunt type to a patient.

Abstract: A signal enhancing and artifact reducing blood pressure cuff for use during the non-invasive measurement of blood pressure. The non-invasive blood pressure cuff has an inflatable bladder and a semi-rigid insert disposed over an outer side of the inflatable bladder for enhancing a blood pressure signal by reducing blood pressure signal attenuation. The semi-rigid insert also acts to reduce the effects of external artifact on the inflatable bladder of the blood pressure cuff. The blood pressure cuff has the insert disposed over the outer side of the inflatable bladder to substantially cover the inflatable bladder when the cuff is wrapped around the limb of the subject. An optional damping device made of an impact absorbing material may be disposed over the outer side of the insert to further reduce the effects of external artifacts. A pocket may be formed over the outer side of the cuff to hold the insert.

Abstract: A flow restrictor is applied to a respiration-channeling device such as a tracheostomy tube, a mouthpiece, or a face mask. The flow restrictor creates a pressure differential which varies with volume flow rate. A pressure reading is taken on either side of the flow restrictor in the respiration-channeling device and from this, a volume flow rate is determined. A data acquisition device is used to derive further pulmonary function parameters from the volume flow rate.
