Abstract: The present invention relates to a linkage structure of a key switch. A second key and a fourth key share one bridge and are connected by a first connecting rod. When the second key or the fourth key is pressed down, the first connecting rod is pushed, so that a first bridge metal dome deforms and is connected to a common contact piece for conduction. A third key and a fifth key share one bridge and are connected by a second connecting. When the third key or the fifth key is pressed down, the second connecting rod is pushed, so that a second bridge metal dome deforms and is connected to the common contact piece for conduction. An input terminal is connected in series to a fuse, and the second key and the fourth key are connected in series to a diode so as to output a rectification half-wave.

Abstract: The present invention provides a motor encoder with a programmable and tactile feedback and an operation method thereof. The encoder includes: a rotary knob; a motor for providing virtual stopping, virtual termination and virtual elastic loading when the knob is turned, and generating a tactile feedback and resistance in different events; a position sensor for providing position information when the knob is started and in a movement process; a controller with a motor driver, wherein the controller is electrically connected with the motor and the position sensor respectively and used for obtaining a position feedback from the position sensor and driving the motor to form closed-loop torque feedback control; and an input interface electrically connected with the controller and used for inputting instruction information to the controller.

Abstract: The present invention provides for compositions and methods for the early detection of prodromal Parkinson's Disease as well as for early medical intervention, especially among individual who may not have been diagnosed but are at an elevated risk of later developing Parkinson's Disease and related conditions.
