    摘要: An AB monomer, useful for the production of condensation polymers, wherein the AB monomer has the structure: A—X—C—Y—B; wherein A is a carboxylic acid or ester or reactive carbonyl derivative, Y is a bisanhydrohexitol unit derived from isosorbide, isoidide or isomannide; X is selected from the group consisting of aromatic rings, substituted or unsubstituted heterocycles, and saturated or unsaturated aliphatic chains; and B is OH and C is an ester carbonyl link with the carbon attached to X and the oxygen attached to Y, and wherein the AB monomer is at least about 98% pure endo-substituted bisanhydrohexitol derivative or an at least about 98% pure exo-substituted bisanhydrohexitol derivative.

    摘要: A feedback device for measuring balance related information, and for producing a stimulation of the skin that encodes that information in a way that is useful to the wearer of the device. At least one sensor detects balance information and transmits at least one balance information signal to a signal processing subsystem. The signal processing subsystem converts the received balance information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.

    摘要: Disclosed is apparatus for determining cross track error between a stored planted location and the actual physical location of plants. An array of active light sensors is mounted on a vehicle for travel above the plants. The array of active light sensors generate an electrical signal from each sensor corresponding to the reflected light from the sensor. A computer system generates a reflectance curve from the array of sensors to determine the location of a plant below the array of sensors and also generates the cross track error.

    摘要: A seated vehicle comprises a frame, one or more first wheels at a first position relative to the frame, one or more second wheels at a second position relative to the frame, and a wheel-positioning system. The wheel-positioning system includes one or more arms pivotally coupled to the frame, and an adjustment mechanism operatively coupled to a first position of the one or more arms. The one or more first wheels are operatively coupled to a second position of the one or more arms. The adjustment mechanism moves the one or more arms between a first position and a second position so that the one or more first wheels are in a first position relative to the one or more second wheels when the one or more arms are in the first position and are in a second position relative to the one or more second wheels when the one or more arms are in the second position.
