According to some embodiments, a system comprises a generator of a truly random signal is connected to an input and feedback device for the purpose of providing a user with real time feedback on the random signal. The user observes a representation of the signal in the process of an external physical event for the purpose of finding a correlation between the random output and what happens during the physical event. In some examples, the system is preferably designed such the system is shielded from all classically known forces such as gravity, physical pressure, motion, electromagnetic fields, humidity, etc. and/or, such classical forces are factored out of the process as much as possible. The system is thus designed to be selectively response to signals from living creatures, in particular, humans.

Patient simulator systems for teaching patient care are provided. In some instances, the patient simulator systems include a patient body comprising one or more simulated body portions. Generally, the patient simulator systems of the present disclosure provide physiological modeling. In one embodiment, the patient simulator includes a maternal simulator comprising a maternal circulatory model, a maternal cardiac ischemia model, and a maternal respiratory model and a fetal simulator comprising a fetal circulatory model, a fetal cardiac ischemia model, and a fetal central nervous system model. A controller in communication with the maternal and fetal simulators coordinates parameters of the maternal circulatory model, the maternal cardiac ischemia model, the maternal respiratory model, the fetal circulatory model, the fetal cardiac ischemia model, and the fetal central nervous system model to simulate physiological characteristics of a natural mother and fetus. Methods of utilizing the patient simulator systems are also provided.

The present invention relates to an apparatus, system, and method for teaching mathematics. Specifically, the present invention relates to a system and method for helping students solve advance multiplication problems and teaching students how to perform the same. Even more specifically, a student may use the present invention to cover up confusing numbers and isolating a single digit for multiplication. The present invention provides students with a space for providing the solution to the single digit multiplication. Further, the present invention allows a student to shift to a different single digit for multiplication without becoming confused with the previously solved multiplications.

A method, system and computer program product are disclosed for performing a virtual experiment using one or more mobile communications devices. In the virtual experiment, one or more users tangibly manipulate one or more mobile devices to simulate an experiment. Each of the mobile devices includes sensors, and these sensors sense a set of parameters of the mobile devices and generate parameter signals. In an embodiment, the method includes processing the parameter signals according to a set of rules to generate processed signals; and using the processed signals to generate a display on one or more of the mobile devices to show features of the simulated experiment. In embodiments of the invention, the method further comprises authoring content for the experiment including declaratively creating the content for the experiment and an associated effect of the content on the experiment to create an experiment manifest.

A three-dimensional rib for a crash test dummy includes at least two layers of a band material and a layer of damping material sandwiched in between the at least two layers of the band material.

An adjustable mounting bracket for mounting a skull of an animal onto a wall or other flat surface. The mounting bracket is adjustable so that the angle at which the skull is held can be changed, so that the mounted skull of the animal can be rotated from side to side, and so that the stinger to which the skull is secured to the mounting bracket can be lifted off of the base of the mounting bracket without removing the base from the wall to which it is secured. The base can be made in a variety of shapes and designs to add to the esthetics of the mount. Adjustment of the mounting bracket does not require any tools. The stinger is removable which facilitates marketing, packaging and distribution requirements in addition to making it easier to attach a skull to it.

A system of construction that uses a discrete repertoire of elastic modular units that interconnect forming assemblies of diverse curved geometries applicable at any scale. Each modular unit is formed with linear elements with less than infinite elastic modulus. The modular units connect to one another under tension creating structural networks that have stored elastic potential energy. The linear elements may be formed of carbon based composite materials and their future permutations, including smart materials. The modular assemblies created using this system have application in terrestrial, space and aquatic environments and as an educational tool.
