Abstract: A method of injecting a substance into an eye is disclosed. A connection between a disposable tip segment and a limited reuse assembly is recognized. A temperature control device is activated to alter the temperature of a substance contained in a dispensing chamber. Dosage information is read. In response to the dosage information, a mechanical linkage interface is advanced to advance a plunger to expel the substance from the dispensing chamber. The mechanical linkage interface is retracted without substantially retracting the plunger to prevent reflux of the substance. Reuse of the disposable tip segment is prevented. The removal of the disposable tip segment from the limited reuse assembly is recognized.

Abstract: An injection device assembly includes a dispensing chamber housing and a plunger. The dispensing chamber housing is coupled to a needle. The dispensing chamber housing has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. A dosage of a substance is cast into the dispensing chamber housing or cast onto a plunger that is inserted into the dispensing chamber housing.

Abstract: A disposable injection device has a dispensing chamber housing and a plunger. The dispensing chamber housing has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for receiving a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The plunger has a plunger interface. The plunger interface mates with a mating surface on a mechanical linkage interface such that force is transferred from the mechanical linkage interface to the plunger along a first direction towards the plunger when the plunger interface is in contact with the mating surface of the mechanical linkage interface, and force is not substantially transferred from the mechanical linkage interface to the plunger along a second direction away from the plunger.

Abstract: A method of delivering a substance into an eye includes recognizing a connection between a tip segment and a limited reuse assembly; receiving dosage information from the tip segment; activating a temperature control device to alter a temperature of a substance to be delivered into an eye; receiving temperature information from a thermal sensor; using the temperature information to control the temperature control device; receiving an input indicating that the substance is to be delivered; and based on the dosage information, controlling an actuator to move a plunger to deliver the substance.

Abstract: An injection device has a dispensing chamber housing, a plunger, and a temperature control device. The dispensing chamber housing has a first part and a second part. The first part is thermally coupled to a needle. The second part is thermally coupled to the first part. The second part has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with an inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The temperature control device at least partially surrounds the dispensing chamber housing and is capable of altering a temperature of the substance in the dispensing chamber. The second part has a greater thermal coefficient than the first part.

Abstract: A limited reuse assembly for an ophthalmic medical device has an actuator with a shaft, a power source for providing power to the actuator, a controller for controlling the actuator, a mechanical linkage interface, and a housing. The mechanical linkage interface is coupled to the actuator shaft and has a mating surface on one end. The housing at least partially encloses the power source, the controller, and the actuator. The limited reuse assembly is attachable to and removable from a disposable injection device.

Abstract: A method and apparatus for upper limb rehabilitation training of coordinated arm/forearm, forearm/forearm and grasping movements of a motor impaired patient comprises a nonrobotic, passive support, an arm/forearm sensor, a gripping device, a grip sensor capable of measuring an impaired grasping force of a grasping of the patient, a computer to process measurements of coordinated and simultaneous impaired arm/forearm, forearm/forearm and grasping movements to control a graphical representation of the arm/forearm and grasping movements in interaction with a virtual environment, and to provide a visual feedback signal to the patient of simulated normal activities of daily living performed with enhanced motor ability relative to the actual impaired motor ability. A visual feedback signal of the simulated activities of daily living is provided to motivate the patient to perform the upper limb rehabilitation movement training despite limited motor ability.

Abstract: This invention provides esters of propofol (2,6,-diisoprophenol). The propofol esters are soluble in water and metabolize rapidly to propofol in the body. The propofol esters are useful as pro-drugs for the same indications as propofol. This invention also provides methods of treating neurodegenerative diseases by administering as effective amount of propofol.

Abstract: A composition of matter which comprises a metallic complex of the formulaM.sup.Z+ L.sub.n IwhereinM is a metal ion of nutritional or therapeutic value;L.sub.n is one or more oligopeptides wherein at least one oligopeptide comprises at least one amino acid selected from the group consisting of nonprotein amino acids and synthetic amino acids;n=1-3,Z=1-6. The metal ion of the metallic complex is selected from the group consisting of chromium, zinc, manganese, magnesium, calcium, copper, iron, vanadium, cobalt, molybdenum, germanium, selenium, and indium. The invention further provides food or drink compositions or dietary supplements which comprise the metallic complex of the invention.

Abstract: A portable lane line protection device, or "line-saver", is positioned on the edge of a swimming pool and bypasses the sharp edge of the pool by creating a smooth surface over the pool's edge. A lane line is placed over the smooth surface of the line-saver, thereby preventing the lane line from contacting the relatively sharp edge of the pool, as the lane line is extended into and out of the pool from a storage point or location (usually on a reel) well above the surface of the pool deck to the water level of the pool (which is usually a foot or so below the surface of the pool deck). The line-saver has a U-shaped channel centrally located therein through which the lane line slides or glides as it transitions between the water level and its storage level or vice-versa. Such channel includes smooth edges that are sufficiently high to prevent the lane line from slipping or pulling out of the channel. The line-saver is made from a light weight material, e.g.
