Abstract: A method synchronizes headset output signals of an extended reality headset having a headset receiver, wherein the extended reality headset is worn by a user when the user is operating a piece of exercise equipment having an exercise transmitter to transmit an exercise output signal. A motion sensing detector detects motion of the user, wherein the motion sensing detector includes a motion transmitter to transmit a motion signal. The method begins with receiving the exercise output signal from the exercise transmitter using the headset receiver. The motion signal is then received from the motion transmitter using the headset receiver. The headset output signals are then synchronized as they are emitted by the extended reality headset to match the exercise output and motion signals such that the user can sense the headset output signals congruently with what the user can feel when exercising on the piece of exercise equipment.

Abstract: A method calibrates an extended reality headset to be worn by a user for use with a piece of exercise equipment having at least one exercise device. The method includes the step of inputting data identifying physical parameters of the at least one exercise device. An operation space is then identified about the at least one exercise device for the user to occupy while using the piece of exercise equipment. A digital control space is then presented with control inputs allowing the user to control the piece of exercise equipment and/or to control the digital rendering of the extended reality environment. A digital rendition of the piece of exercise equipment and the at least one exercise device is rendered in the view of the user wearing the extended reality headset while operating the piece of exercise equipment.

Abstract: The present invention provides for a network connected training projectile that provides user feedback and is used to determine a trainee's proximity to an appropriately sized explosive blast zone. The invention solves the unmet need for close combat indirect fire (mortars and grenade launchers), or hand grenades which can be safely used in live training exercises. The invention further solves that such use is interactive with the training environment providing the ability to calculate the extent personnel participating in a training exercise would be affected by the training grenade in a real-life scenario. The invention further determines mortality of participants who would have been affected by the training grenade.

Abstract: The present invention describes a device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate left cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions.

Abstract: A process for converting sulfur-containing carbonaceous fuel into a combustible product gas is described. The fuel, in the form of fine particles, is mixed with a first aqueous solution containing dissolved alkali metal carbonate at approximately atmospheric pressure to form concentrated slurry. The slurry is pressurized and fed into a gasifier operating at an elevated pressure. An oxygen-containing gas is also fed into the gasifier where it reacts with the fuel to produce hydrogen and carbon monoxide-containing gases and heat the reacting mixture to about 900-1400° C. Oxygen combined with steam may also be used as the oxidizer to produce hydrogen-rich product gas. Alkali metal salts in the slurry are melted and absorb sulfur from the reacting fuel to form a liquid smelt containing alkali metal sulfide.

Abstract: The present invention preferably includes a system and method for allowing a plurality of input stations such as touchscreen input devices, for example, to simultaneously provide input to a central processing unit executing a computerized simulation program such as a game simulation program. The invention allows a plurality of input groups, for example, to be received by the central processing unit. Each received input group preferably causes a graphical effect on a parameter or function provided by the simulation program. Each graphical effect is preferably displayed on a corresponding computer monitor, for example, thereby allowing a first participant to view a first graphical effect and a second participant to view a second graphical effect. The system can allow participants exercising control over the touchscreen input devices to experience a more real “feel” of the game, that is, a feeling as though the participant were participating in the real-life scenario emulated by the simulation program.

Abstract: A drug recognition system for patient simulators is provided for use in training in anesthesiology, operating rooms, and emergency rooms. In a patient simulator mannequin, simulated intravenous drugs are administered by syringe. Each syringe used on a multiple syringe manifold contains a simulated drug fluid and an integrated circuit preprogrammed with a drug type and concentration. A flow sensor provides the amount of simulated drug administered. A computer senses the drug type and concentration from the integrated circuit attached to the syringe, and measures the amount administered from the flow sensor. The drug type, concentration, and amount administered is used by the computer, along with other measured parameters, body and drug models, and trainer input, to cause the simulator mannequin to react in the proper or desired manner. In an alternate embodiment, the system can be used to record the type, concentration, and amount of actual drugs administered to a real patient.

Abstract: A computerized system determines the trajectory of an object based upon video images captured by cameras at two fixed viewpoints. Two video cameras are arranged so that each will contain the anticipated trajectory of an object within its field of view. The video cameras are synchronized and have shutter speeds slow enough to yield an image of the object containing a blur due to the object's motion. An audio or an optical trigger, derived either from the event causing object motion or from the object itself, causes at least two images to be captured in digital frame buffers in a computer. Software in the computer accesses each of the digital frame buffers and subtracts the background image to isolate the blurred object. A two-dimensional projection of the object's trajectory is derived for each frame buffer image. The two dimensional trajectories are combined to determine a three dimensional trajectory.

Final state parameters for the monitored thermohydraulic system are determined by solving the equation set in response to the sensed parameters by a momentum method and pressure search method, using a constant time step in the calculations.
