摘要： A controller-transmitter transmits acoustic energy through the body to an implanted acoustic receiver-stimulator. The receiver-stimulator converts the acoustic energy into electrical energy and delivers the electrical energy to tissue using an electrode assembly. The receiver-stimulator limits the output voltage delivered to the tissue to a predetermined maximum output voltage. In the presence of interfering acoustic energy sources output voltages are thereby limited prior to being delivered to the tissue.

摘要： The present invention relates to a positively-charged body for a triboelectric generator and a triboelectric generator including the same. More particularly, the present invention relates to a positively-charged body based on a two-dimensional material including silicon oxide, and to a triboelectric generator including such a positively-charged body. Thus, a conventional manner in which the positively-charged body is mainly composed of a metal thin film or polymer is not used, but the positively-charged body is made of the silicon oxide and the two-dimensional material. Thus, charge generation efficiency of the generator via contact between the positively-charged body and a negatively-charged body may be dramatically enhanced.

摘要： An optical element driving mechanism has an optical axis and includes a fixed portion, a movable portion, and a driving assembly. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The driving assembly moves in a first direction to move the movable portion in a second direction, wherein the first direction is different from the second direction.

摘要： An electrical power system for a resource extraction system includes a thermoelectric generator assembly configured to couple to a wall of a fluid containment structure. A portion of the thermoelectric generator assembly is configured to be disposed within an opening in the wall that extends through the wall to a cavity within the fluid containment structure. In addition, the thermoelectric generator assembly includes a thermoelectric generator configured to be in thermal communication with a fluid within the opening and with an environment external to the fluid containment structure. The thermoelectric generator is configured to generate electrical power in response to a temperature differential between the fluid within the opening and the environment.

摘要： Provided is a MEMS condenser microphone, including a base plate, a spacer and a membrane. The membrane is supported above the base plate by the spacer. The base plate, the spacer, and the membrane enclose a vacuum cavity. An end of the membrane close to the vacuum cavity is connected, by means of a connecting rod, to an electrostatic clutch. The electrostatic clutch is connected to a capacitive sensing structure. The microphone has the advantage of allowing microphone performance over a wide range of atmospheric pressures which is likely expected by customers. This is achieved electrostatically in a purely passive way which has an advantage over other designs which require complex electronics and active control. Physically decoupling the membrane and sense structure simplifies the design of the sense structure as only small AC perturbations of the rotor need to be considered with no DC changes in rotor position.
