Abstract: A biocarrier loaded with up to 60 % by weight of a mixture including a biological control agent. The biocarrier is derived from the residual cell mass remaining after lipids and soluble proteins and sugars have at least in part been removed from crushed or ground oil seeds. The biological control agent is an agrochemical, biopesticide or mixtures thereof. When the product is formulated as a granule, tablet or briquette it has good hardness and does not dust, thereby reducing operator exposure to the biological control agent.

Title: Apparatus for improving vision and resolution of retinal images
Inventor: LIANG JUNZHONG
IPC: G01J9/00
Filed: 1997-12-23
Granted: 2009-11-24
Abstract: An apparatus for improving vision and resolution of retinal images comprises a point source produced on the retina (101) of a living eye (100) by a laser beam (102).  The laser beam reflected from the retina is received at a lenslet array of a Hartmann-Shack wavefront sensor (148) such that each of the lenslets forms an aerial image of the retinal point source on a CCD camera (146) located adjacent to the lenslet array. The output signal from the CCD camera is acquired by a computer (150) which processes the signal and produces a correction signal which may be used to control a compensating optical or wavefront compensation device such as a deformable mirror (118). It may also be used to fabricate a contact lens or intraocular lens, or to guide a surgical procedure to correct the aberrations of the eye. Any of these methods could correct aberrations beyond defocus and astigmatism, allowing improved vision and improved imaging of the inside of the eye.
