Abstract: A surgical access device includes two opposed side members each of which carries a downwardly depending flange. One lateral member adjustably connects a first end of the first side member to a first end of the second side member, with at least one of these first ends being moveable along a length of the first lateral member, thereby permitting adjustment of the space between the first ends. A second lateral member adjustably connects the second end of the first side member to the second end of the second side member, with at least one of these second ends being moveable along a length of the second lateral member, thereby permitting adjustment of the space between the second ends.

Abstract: The invention is an articulated frame for attachment to a trailer hitch for purposes of facilitating alignment and coupling of the trailer hitch to a vehicle hitch.

Abstract: A method for heating a liquid or food. The method includes the steps of (1) obtaining a tool including an interconnected combination of a clip, a handle, and a hook; (2) inserting a vessel capable of holding a liquid within the clip; (3) placing a liquid within the vessel; and (4) heating the liquid.

Abstract: A cushion having a plurality of inflatable and deflatable cells useful for periodically shifting the points of contact between the cushion and a body supported by the cushion in order to reduce or eliminate the development of pressure sores. The cushion includes one or more of (i) at least two encircling cells shaped so as to define a central concavity in the upper surface of each of the encircling cells, (ii) at least one repositionable cell, (iii) at least two cells having contoured upper surfaces which define a longitudinally extending laterally concave channel, and (iv) two groupings of independently inflatable and deflatable cells arranged asymmetrically about a longitudinal axis.

Abstract: A power generating heating unit including a housing, a turbine for generating mechanical energy and heated exhaust gas, an electrical generator for converting the mechanical energy to electrical energy, and a heat exchanger for transferring heat from the heated exhaust gas to a fluid.

Abstract: Protective headguards comprising a front panel, a rear panel, and a means for releasably connecting the lateral ends of the front and rear panels. At least one and preferably both of the front and rear panels comprise layers of at least a shell, a shock absorbing liner and a comfort liner.

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 exercise machine (1) having a cable (16) connected at a first end to a longitudinally reciprocable target pad (13) and sequentially extending around a first pulley (57) located on a lower crossbar (56) of the machine (1), underneath the target pad (13), and then connected to a spring (17) anchored to a support (18). A pair of handles (14, 15) is attached to legs (4, 5) which support the frame (3) of the machine (1). A user (2) is able to kick the target pad (13) and thereby strengthen muscles and develop coordination needed in the martial arts.

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 compression 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.
