Accurate simulation of sport to quantify and train performance constructs by employing sensing electronics for determining, in essentially real time, the player's three dimensional positional changes in three or more degrees of freedom (three dimensions); and computer controlled sport specific cuing that evokes or prompts sport specific responses from the player that are measured to provide meaningful indicia of performance. The sport specific cuing is characterized as a virtual opponent that is responsive to, and interactive with, the player in real time. The virtual opponent continually delivers and/or responds to stimuli to create realistic movement challenges for the player.

A numerical procedure for simulating the behavior of incompressible, viscous fluid in a casting/molding process. The method is based on classical fluid dynamic equations and uses control volume-finite element and numerical techniques to solve the momentum and energy equations to obtain solution for the variable parameters. The method incorporates five additional modules which simulate fluid flow in the shot sleeve, heat transfer between the die and the heat transfer fluid, die cooling by lubricant, formation of mend line. These additional simulation modules produce realistic boundary conditions, and replace many of the assumptions that would have to be made, to solve the governing equations. These added improvements ensure a faster convergence of the numerical solution and a more realistic simulation of the die casting process.

A device to deliver various combinations of scents in rapid succession to a user's nose in conjunction with video graphic images and or sounds. The device consists of an air compressor which forces air through a bank of valves. The valves can be mechanically, electrically or pneumatically actuated. The valves can be of an on/off or proportional flow type. Each valve delivers compressed air to a fragrance holder. The air carries away the scent molecules which have entered the gas phase. This air is then mixed with air from all other fragrance holders, whose inlet valves were open, in the packed column. The final mixture is delivered to the user via nasal tubing and is emitted right below the wearer's nose. Other devices such as a mask covering the nose or a stand, which the user positions their face next to, can be used to deliver the scent to the user. The scent is then drawn away into a scent scrubber. The invention can coordinate the delivery of scents so that they complement video or audiovisual images being displayed. This is done by utilizing a microprocessor or computer controller which receives the electronic output from the music video producing device.

The present invention provides an emulation system having a control system that allows the testing of a satellite control system with all of its hardware in place, i.e. fully integrated. The emulation methodology is applicable to the case of either a rigid spacecraft or a flexible spacecraft, provided that the spacecraft's sensors and actuators are stowed to the rigid part of spacecraft in the case of a flexible spacecraft. Practically, the latter condition is not restrictive, as the actuators and sensors are usually placed rigidly in the satellite bus, while the satellite solar panels constitute the flexible elements. The control system is used to tune the mass properties and dynamic behaviour of a rigid ground-spacecraft in a 1-G environment to those of a flight-spacecraft in 0-G. A six-axis force/moment sensor is placed at an interface of the ground-spacecraft and a manipulator. Signals received from the force/moment sensor, and in some cases signals relating to the position and velocity of manipulator joints, are received into the control system.

A proportional force input apparatus for an electronic device includes a mechanism operable by a user of the electronic device, such as a stylus inserted into a spring-loaded socket of the device. The mechanism provides a tactile feedback to the user proportional to a force applied by the user. A variable strength sensor detects the force applied by the user to the mechanism and converts this to an electrical signal proportional to the force applied by the user. A processor operates to input the electric signal from the variable strength sensor and provide force information to an application running on the electronic device. Optionally, a second sensor can detect rotation of the stylus. As a result, a stylus can be used to provide vector information to an application such as a game.
