Patent number: 6148814Abstract: A method and system for managing mechanical ventilation of patients with respiratory disorders is described. The main objective of the system is to generate executable instructions for patient care which take into account a large number of parameters of patient condition and ventilation. Data regarding the state of the patient are stored in a database. Patient data are processed according to a set of protocols which contain rules for patient care decisions arranged in a logical sequence to generate detailed, executable instructions for patient care. Instructions are updated when new data are entered into the database. The data can be acquired in an automated fashion, or the clinician can be instructed to collect and enter new data into the clinical database. Likewise, patient care instructions can be carried out automatically or manually, but it is preferred that instructions are carried out manually as a safety check.Type: GrantFiled: February 8, 1996Date of Patent: November 21, 2000Assignee: IHC Health Services, IncInventors: Terry P.

Patent number: 5954598Abstract: The present invention is a device for improving hand-eye coordination in a baseball player to improve swing and targeting of the ball. The invention includes a device for presenting a fixed target to the ballplayer which corresponds to the location of the incoming ball at the time that it should be struck by the bat, as well as a method for training the player with the use of this device. In the preferred embodiment of the invention, the target is held in a fixed position with respect to the upper lead arm of the player, by means of a mechanical linkage. The target position is selected by having the player extend his arms as if swinging to hit a ball and placing the marker at the position of the "sweet-spot" of the bat. The player uses the device to practice positioning his body so that the pitched ball consistently hits the target.Type: GrantFiled: April 28, 1997Date of Patent: September 21, 1999Assignee: Edgewise, L.L.C.Inventor: Joseph W.

Patent number: 5749111Abstract: A cushion that includes a cushioning element. The cushioning element has a number of substantially parallel elongate columns formed in a gelatinous cushioning media. The columns are configured so that when a force is applied to the cushioning element in a direction that is generally parallel to the longitudinal axes of the columns, the cushioning element will yield by a combination of compressability of the cushioning media and bucklability of the walls of the columns. In particular, the walls of columns which are located beneath a protruberance on an object being cushioned tend to buckle, permitting the cushioning element to conform to the shape of the cushioned object while evenly distributing a supporting force across the contact area of the cushioned object and avoiding pressure peaks. The preferred cushioning media is a gelatinous elastomer or gelatinous viscoelastomer. Various configurations of cushioning elements, including sidewall supports, are disclosed.Type: GrantFiled: February 14, 1996Date of Patent: May 12, 1998Assignee: TekSource, LCInventor: Tony M. Pearce

Patent number: 5726896Abstract: An iterative spline interpolation method for a numerically-controlled machine tool device is disclosed. The non-uniform rational B-spline (NURBS) curve inputted to the numerically-controlled machine tool is interpolated with a constant step size providing the ability to maintain a controlled velocity to within a specified tolerance. In addition, the distance left to travel on the curve is obtained by a unique spline node-based approximation method providing accurate acceleration and deceleration control. The rational spline interpolation method provides significant reduction in the amount of data required to produce smoothly machined pieces while providing accurate machining of conic sections not possible by previous spline interpolation methods.Type: GrantFiled: August 29, 1996Date of Patent: March 10, 1998Assignee: University of Utah Research FoundationInventors: Ji Jia, Elaine Cohen, Samuel H.

Patent number: 5695543Abstract: A method and system for recovering metal from steel waste products is disclosed. This method and system works on such hazardous and/or toxic wastes as mill scale, flue dust and slag. This method and system operates by mixing the steel waste produce with a flux composition and then melting the mix in a single phase two electrode electric arc furnace. Once the mixture is melted by the heat from the electrodes, the electro-magnetic field induced in the melted mixture serves to enhance the recovery from the steel waste product of useful steel material. Furthermore, this method and system provide a cost effective solution to the hazardous waste disposal problems impacting steel refineries around the world and does so in a manner that removes the toxicity of the waste while producing a variety of useful products, including high grade steel and neutralized fill.Type: GrantFiled: May 10, 1996Date of Patent: December 9, 1997Assignee: D & S Technologies, Inc.Inventor: Desmond L. Shields

Patent number: 5626657Abstract: A composite mixture of spherical objects and lubricant useful for its cushioning properties is disclosed and claimed. The composite mixture may be composed of microspheres typically less than 2000 microns in diameter with inert atmospheres sealed within their interiors and any of a variety of lubricants facilitating sliding and rolling movement between microspheres. Typically the composite mixture includes lubricant in a quantity sufficient to substantially coat the exterior surface of essentially all of the spherical objects, but in a quantity less than would cause dispersion of the spherical objects in the lubricant sufficient to physically separate the spherical objects from each other and substantially reduce the sliding and rolling contact of the spherical objects with each other. The preferred lubricant is a visco-elastic fluid that has a principle molecule and a cross-linking agent.Type: GrantFiled: August 22, 1996Date of Patent: May 6, 1997Assignees: TekSource, LC, Nike, Inc., Nike International, Ltd.Inventor: Tony M.

Patent number: 5576972Abstract: An intelligent area monitoring system having a field sensor, a neural network computer, and a communications apparatus is disclosed. The system has the capability of detecting and monitoring the location and identity of people, animals, and objects within an indoor or outdoor area for the purpose of intrusion detection, theft deterrence, and accident prevention. The neural network computer accepts the input signals from the field sensor and forms a virtual model of the monitored area from the input. Any changes that occur within the monitored area are communicated to system users. The sensors can be active or passive, analog or binary, and the system is optimally configured with a mix of different sensor types such as vibration, sound, infrared, optical, microwave, and ultrasonic. Each analog sensor provides an analog output which varies in proportion to the size and distance of its target.Type: GrantFiled: March 28, 1995Date of Patent: November 19, 1996Inventor: Dana C.
