An artificial retinal system includes an external optical device having an image generator and a background light generator, and a retinal implant chip having a solar cell and a stimulus generator. The stimulus generator is disposed to receive a target image projected by the image generator and a background light provided by the background light generator, and receives the electrical power from the solar cell. The stimulus generator includes an image sensing stimulator operable to convert the target image into electrical stimuli, and a contrast enhancer for reducing effect of the background light on the electrical stimuli.

A surgery assisting instrument for retinal surgery includes a cylinder and a strip connected with each other. The cylinder and the strip are made of a soft and biocompatible material. The cylinder is preferably connected with the strip at a side surface and close to an edge of the strip. The surgery assisting instrument is placed in a fornix around an eye at a position according to a retinal tear. The cylinder is pressed against the eye and the strip is pressed against the eyelid. Thus the retina is forced toward the back wall of the eye.

A protect-control device capable of limiting current for reducing noise resulting from switchover of a motor includes a motor coil set, a driving unit, a sensing unit and a control unit. The motor coil set constitutes a motor. The driving unit is electrically connected to the motor coil and provides a driving level to pass through the motor coil for driving the motor. The sensing unit is electrically connected to the motor coil set, provides a preset reference level, detects the driving level, compares the driving level to the preset reference level and outputs identifying signal. The control signal is electrically connected to the driving unit, the sensing unit and a Hall component, adjusts the driving level based on the identifying signal for driving unit output maintaining a basic duty cycle.

A motherboard with multiple power selectivity. The components formed on the motherboard comprise a 20-pin ATX power male connector and a 4-pin ATX power male connector. The 20-pin ATX power male connector is coupled electrically with devices and a CPU socket on the motherboard through circuits thereon. The 4-pin ATX power male connector, with four pins configured in line, is applied to provide individual +12 volts/ground/ground/+5 volts power. The 4-pin ATX power male connector is coupled electrically with the CPU socket.

A water stop module for use with a spray nozzle printing press dampener includes a shield maintained in a housing having an aperture to allow undisrupted fluid flow therethrough and a guide track for directing the shield to block the aperture. A pair of cogwheels with sprockets in engaging relation with the shield are rotatable to drive the shield along the guide tracks by a regulated amount to enable the area of coverage of fluid emerging from the aperture to be determined.

The present invention provides a device for stimulating optic nerve fibers. The device includes a plurality of columnar electrodes and a power source. The columnar electrodes are disposed respectively in parallel to a length direction of an optic nerve of a human eye and are also disposed around the optic nerve along a circumferential direction thereof. Each of the columnar electrodes has a length. The power source is configured to supply power to the columnar electrodes. A human retina consists of the optic nerve fibers, which are connected to the optic nerve and a macular area of the human eye in a form of layers. The columnar electrodes are configured to stimulate the optic nerve fibers around the optic nerve with electrical stimulation.

A neural sensing method includes the steps of: configuring an array of sensing units on a retina of a user, each of the sensing units detecting a signal and generating a sensed signal; generating a control signal by a control signal generator and transmitting the control signal to at least one electrode installed in a periphery of each of the sensing units; isolating each of the sensed signals by the control signal, thereby suppressing the mutual interference between the sensed signals by the control signal; and generating and outputting a processed signal to at least one neuron via a signal processing module with reference to the control signal and the sensed signals. The control signal has a signal strength lower than the sensing threshold of the at least one neuron.

The present invention provides a deformable tire including a plurality of spokes. A first end of each of the spokes is connected to a core structure, and a second end of each of the spokes is connected to a tire body. A first length is provided between each of the tire bodies and the core structure connected by each of the spokes, and the spokes are elastic. The core structure is configured to fix and support the plurality of spokes, and each of the first lengths is dynamically adjusted by the elasticity of the spokes.
