Abstract: A surgical training device is provided. The training device includes a model for practicing the passage of needle and suture. The model includes a base with a plurality of openings configured to receive a plurality of suture tabs. The suture tabs are made of elastomeric material. Some suture tabs includes pre-formed tab apertures for the passage of a suture. Other suture tabs include a penetrable area through which a suture needle may penetrate for passing a suture. The suture tabs are movable with respect to the base to orientate them at different angles with respect to the base. The base itself may include portions that are angled with respect to each other. The suture tabs are movable with respect to the base to pull, expose or open the tab apertures and surfaces. Some of the tab apertures are slits that open upon being pulled relative to the base requiring the user to practice holding the tab while passing the needle through the tab.

Abstract: A tactile graphic display comprises an array of pin assemblies that can be individually activated to rise a selective distance above a plane, taking the shape of 3D objects and text in essentially real time. Each pin assembly of the array is operatively coupled to a permanent magnet that is slidable within an electromagnetic coil. When current is applied in a first direction to the coil, the magnet is repelled by the coil, causing it to move upwards and thus causing the pin to project from the array. When current is applied to the coil in the opposite direction, the magnet is attracted to the coil and moves downward, causing the pin assembly to retreat from the array. A latch member is configured to selectively engage and disengage a surface feature on the pin assembly for locking and unlocking a position of the pin assembly relative to the frame.

Abstract: A system is provided enabling do it yourself body stenciling and/or body art. In particular, the system of the invention provides a body tight removable mask that masks an area of the body for body painting. The mask is sized to fit a particular portion of the torso or an appendage of a subject individual, and masks a standard area to enable an unskilled artist to paint a portion of the subject individual. The stencil can mask a logo of a sports team or other form such as a swimsuit form on a wrist or ankle or upper torso, forehead, or a bathing suit area of the subject individual. In its simplest form, the stencil is a mask of the thighs, and the waist, for example, with a preferably elastic mask panel that can preferably be easily removed once the basic painting is complete. Advantageously, the invention enables websites that feature body painting, such as Sports teams, Universities, Sports Illustrated or Fashion TV, to sell stencil product in association with displays of body painted models.

The tissues, organs, and/or organ systems can be modified by enhancing their electrical conductivity, by including simulated contents mimicking what would normally be present in live animals, and by having fake blood perfusing through them.

The device also comprises a first anchor and a second anchor positioned on the first side of the base. The first and second anchors are each connectable to a segment of tissue so that the tissue is suspended therebetween in use of the device. An actuator is associated with one or both of the first anchor and the second anchor. The actuator is actuatable to cause relative movement of the first and second anchors along the plane. A force gauge is configured to measure a force applied to the tissue when the first and second anchors are moved relative one another by the actuator.

Abstract: Flammable untreated firefighter training gear is Structural Firefighting Gear (SFG) manufactured without the use of chemical treatments that create resistance to flammability. Stated differently, the gear is SFG that is flammable in the sense that the resulting clothing is as flammable as the uncoated fabric from which the SFG is manufactured. The majority of a firefighter's day is spent preparing for responses to an incident, rather than actual incident response. In other words, the most significant period of time that a firefighter spends wearing their SFG is not during a dangerous incident response scenario, but rather while taking part in the extensive training and preparation to ensure both mental and physical readiness for incidents. As a result, firefighters are often wearing their SFG when its fire and chemical resistance treatments are unnecessary.

Abstract: Technologies for providing assistance to a surgeon during a surgical procedure are disclosed. An example method includes identifying a medical condition of a patient and recommending surgical procedures for treatment. An optimal surgical procedure is then determined based on correlations between the medical condition of the patient and outcomes of previous surgical procedures for other patients previously suffering from the medical condition. A 3D model of the patient may be created using current images of an affected area of the patient. Successively, a surgeon is trained using a Virtual Reality simulation. During the training, the surgeon may be allowed to provide annotations. Further, the recommended surgical procedures are based on medical data of the patient, including medical images. Surgical paths are retrieved for addressing the surgical need of the patient, and the surgical paths may be overlaid on image segments, for display for the surgeon.
