    摘要: The present invention relates to a retina implant for the functional electrostimulation of a retina as a function of incident light. The retina implant has a stimulation chip that is designed to be implanted in the area of the retina of an eye. It further includes a radiation receiver that provides energy for the stimulation chip as a function of invisible radiation that occurs. In accordance with one aspect of the present invention, the radiation receiver is designed so as to be implanted in the area of the eye in a fashion spatially separated from the stimulation chip. The stimulation chip also has decoupling means in order to separate invisible scattered radiation from impinging visible light.

    摘要: An active retina implant has a multiplicity of pixel elements that convert incident light into electric stimulation signals for cells of the retina with which stimulation electrodes are to make contact. Each pixel element is provided with at least one image cell that converts incident light into electric signals, there being provided at least one amplifier whose input is connected to the image cell and whose output is connected to at least one stimulation electrode to which it supplies a stimulation signal. Also provided is an energy supply which provides externally coupled external energy as supply voltage for the image cells and the amplifiers. The image cell has a logarithmic characteristic according to which incident light of specific intensity is converted into electric signals of specific amplitude. The stimulation signal is supplied in the form of analog voltage pulses of specific pulse length and pulse spacings, the pulse amplitude being a function of the intensity of the incident light.

    摘要: A process for carrying out functional assays on test cells is described comprising the following steps: a) providing an array of measuring points which are separate from each other and to which in each case capture molecules to which said test cells can bind are immobilized, b) generating a mixture of said test cells and of reference particles which are capable of binding to said capture molecules and which are distinguishable from said test cells, c) contacting the mixture of step b) with the array so that test cells and reference particles can bind to each measuring point, and d) determining the ratio of bound test cells of interest to bound reference particles for at least some of the measuring points. In a further process, at least one measuring point with its assigned capture molecules is distributed between a plurality of measuring areas in the array, which are arranged at various sites in said array. In another process, the array is agitated, after contacting with the test cells and, where appropriate, the reference particles.
