A stool sample collector is comprised of a sheet of water-soluble material such as heavy-weight polyvinyl alcohol film, six to nine inches by 20 to 26 inches. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. Further, the invention provides methods and systems for using a modifiable resist layer that provides a first set of optical properties before exposure and a second set of optical properties after exposure. This damps the movement of the hydraulic actuator in the region of an end position. Based on the selection, at least one coordinate set corresponding to the selection and associated with at least one data field of interest is generated. The adjust plate is formed of one of an electrically conductive material, a superconductive material and a dielectric material.
