Abstract: This invention relates to gravity reactive braking systems. According to the invention there is provided a brake system to control speed in a forward direction for descending inclined surfaces and a brake system for controlling rollback when ascending an inclined surface. The speed pacer braking assembly includes a downhill activator for selectively engaging a disc brake system when a predetermined inclined is reach. The anti-rollback assembly comprises a pair of graded brake cam structures operatively disposed adjacent wheels wherein the natural pull of gravity and the configuration of the cams operate to allow passage of wheels in both directions when on flat surfaces and in only a single direction when on an incline. When on an incline, gravity operates to dispose cams relative to the wheels such that rotation of wheels in one direction is hindered by a thickening of cam body caused by rotation of cam about its axis.

Abstract: This invention relates to a device for simulating life-like conditions during eye surgery. The device includes a prosthetic head which includes an eye socket coupled to a fluid line adapted to create negative pressure or a vacuum in the eye socket. An eye for practicing surgical techniques can be placed in the socket and negative pressure used to hold the eye in the socket in a manner which feels analogous to the way an eye feels to a surgeon operating on a live human.

Abstract: As disclosed herein, the present invention provides methods and systems for detecting, measuring, or monitoring the presence of absence of at least one emotion in a subject from a speech sample obtained from the subject. In particular, the methods and systems of the present invention comprise extracting at least one feature from the speech sample, assigning the speech sample a score using a weighted frequency band scoring scheme, and comparing the score with a general reference model or a control. As disclosed, the methods, systems and computer programs of the present invention provide detection error rates of about 4.7% or less, preferably about 3.0% or less, more preferably about 2.0% or less, most preferably about 1.0% or less and thereby reduced the detection error rate by about 60.0% or more, preferably about 70.0% or more, more preferably about 80.0% or more, even more preferably about 90% or more, and most preferably 95.0% or more than the detection error rates of prior art methods.

Abstract: We describe a bacterial delivery system for the delivery of DNA and antigens into cells. We constructed an attenuated bacterial vector which enters mammalian cells and ruptures delivering functional plasmid DNA and antigens into the cell cytoplasm. This Shigella vector was designed to deliver DNA to colonic surfaces, thus opening the possibility of oral and other mucosal DNA immunization and gene therapy strategies. The attenuated Shigella is also useful as a vaccine for reducing disease symptoms caused by Shigella.
