  • Low-voltage controller with dimming function and method
    Patent number: 10015867
    Abstract: A low-voltage controller (LVC) is configured to utilize a low-voltage signal to operate a high-voltage load, such as, for example, a lamp. The LVC is configured to receive a low-voltage step signal at a switch input. The LVC has a line input for connection to a source of power at a line voltage and a load output for connection to a first load, and a dimmer for setting an intensity of the first load. Subsequent step signals may alter the intensity of the load. A method for low-voltage control of a load is provided. A method includes the steps of receiving a first switch signal at a switch input of an LVC; setting a lamp to a first intensity; receiving a second switch signal at the switch input; and setting the lamp to a second intensity.

  • Method and Apparatus to Provide Safety Checks for Neural Stimulation
    Publication number: 20180169413
    Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.

  • Transretinal implant and method of manufacture
    Patent number: 9993367
    Abstract: The invention is a retinal implant device to stimulate a retina of an eye thereby producing a specific effect in the eye, such as a vision or drug treatment of a chronic condition. The retinal device is made of a retinal implant that is positioned subretinally and that contains a multitude of stimulation sites that are in contact with the retina. A connection carries a stimulating electrical signal or a drug. The connection passes transretinally through the retina and into a vitreous cavity of the eye, thereby minimizing damage to a nutrient-rich choroid. A lead is attached to a source of drugs or electrical energy, which is located outside the eye. The lead passes through a sclera at a point near a front of the eye to avoid damage to the retina.
