Abstract: A self-contained speed indicator (10) that can be placed next to a weldment (11) and configured for a desired speed, which then provides a target speed indicator (10) to help a welder (14) practice maintaining that desired speed.

Abstract: A system for assessing electrical wiring skills that includes an electrical assessment circuit for transmitting a unique power signal through each of the hot, neutral and ground wires in an electrical circuit, whereby correctness of wired connections can be detected and wiring defects can be reported with an identification of the specific wire or wires that are incorrectly connected.

Abstract: A system (10) and method for determining welding speed employing a series of optical sensors (28) positioned along a weld joint (12) that collects light source location data during an actual weld.

Abstract: A doll for educating caregivers about Shaken Baby Syndrome comprises a head portion, a body, and may comprise transparent skin. The head portion may have a simulated brain disposed therein. The head portion is floppably connected to the body. The doll may further comprise a first chamber and a second chamber containing simulated blood, the simulated blood being visible in the first chamber after acceleration experienced during a shaking episode, but otherwise being concealed from view in the second chamber. A plurality of acceleration sensors may be disposed within the doll to detect acceleration experienced during a shaking episode, and the plurality of acceleration sensors may trigger warnings to the caregiver when portions of the doll experience acceleration sufficient to endanger an infant.

Abstract: In one aspect the pregnancy simulation outfit comprises (i) a vest, (ii) a pair of protuberances configured and arranged on an upper portion of a frontal area of the vest for depicting the enlarged breasts of a pregnant woman when the vest is worn, (iii) a weighted element, and (iv) a pouch in a lower portion of the frontal area of the vest accessible from the outside surface of the vest for accommodating insertion and removal of the weighted element into and out from the pouch while the vest is worn without doffing the vest.

Abstract: An infant simulator comprising a mannequin having a temperature sensor effective for sensing the environmental temperatures to which the mannequin is exposed, and a means effective for recording the sensed temperature.

Abstract: An infant simulator capable of emulating the care requirements of an infant and recording the quality ot care and responsiveness of a person caring for the infant simulator and/or signaling the person caring for the infant simulator when care is required. The infant simulator is capable of sensing the unacceptable environmental conditions of exposure to direct sunlight and exposure to temperature extremes and to which the infant simulator is subjected. The infant simulator is also programmed with the ancillary features of multiple behavior modes based upon the historic level of care experienced by the infant, and/or the health of the infant, and perceptibly different demand and distress signals for each type of environmental event.

Abstract: An addiction simulator for use in an educational program, operable for (i) periodically requesting simulated addictive behavior, (ii) receiving a satisfaction signal from an assigned individual in response to a generated request, representing consumption of an amount of addictant in limited supply, and (iii) refusing acceptance of a satisfaction signal when the supply of addictant has been exhausted. The duration of the interval between requests can based upon a physiological characteristic of the assigned individual.

Abstract: A portable refusal skills training educational tool including an interactive electronic system within an enclosure, and method practicing refusal skills employing the educational tool. The interactive electronic system includes (i) a means within the enclosure for periodically generating a perceptible proposal to participate in addictive behavior, (ii) a speech recognition system effective for receiving and identifying a verbal refusal statement spoken in response to a generated proposal, and (iii) a reporting mechanism. The reporting mechanism includes at least one of (A) a means for reiterating perceptible proposals to participate in addictive behavior until the verbal refusal statement is received and identified in response to a proposal, (B) a means for generating a perceptible positive-reinforcement signal when the verbal refusal statement is received and identified in response to a proposal, and (C) a means for recording data useful in evaluating responses to proposals.

Abstract: An infant simulator with a neck linkage connecting the head to the torso which includes at least (a) a longitudinally extending central shaft fixedly attached to the torso proximate the lower end of the central shaft, (b) a socket fixedly attached to the head, (c) a ball fixedly attached to the central shaft and pivotally captured within the socket for permitting pivoting of the socket relative to the central shaft as between a longitudinally aligned central rest position and a longitudinally angled position, and (d) preferably a spring coaxially positioned around the central shaft and captured between the socket and the upper end of the central shaft, whereby the spring biases the socket into the longitudinally aligned central rest position.

Abstract: An infant simulator (5) is capable of emulating the care requirements of an infant, recording the quality of care, responsiveness of a person caring for the infant simulator (5), and/or signaling the person caring for the infant simulator (5) when care is required. The infant simulator (5) is capable of sensing the unacceptable environmental conditions of abusive impact, abusive compression, improper positioning, exposure to loud noises, over-stimulation, exposure to smoke, exposure to direct sunlight, exposure to temperature extremes to which the infant simulator (5) is subjected, and periodically demanding that the student change the diaper, feed, burp the infant, rest the infant, and rock the infant.

Abstract: An infant simulator capable of emulating the care requirements of an infant and recording the quality of care and responsiveness of a person caring for the infant simulator and/or signaling the person caring for the infant simulator when care is required. The infant simulator is capable of (i) sensing the environmental conditions of position, temperature and comparison to which the infant simulator is subjected, and (ii) periodically demanding that the care-provider change the diaper, rock the infant, feeding the infant, or burp the infant simulator. The infant simulator is also programmed with the ancillary features of providing positive feedback when the proper interaction is provided in a timely fashion, an escalating demand signal when the proper interaction is not provided in a timely fashion, an identification system requiring the assigned care-provider to be present in order to satisfy a demand event, an unsatisfiable fussy period, and multiple behavior modes (i.e.
