摘要： The invention relates to a method for providing short-circuit protection for a resistive AC load, wherein the load is connected with an AC power supply through an active controlled switch controlled by a controller. The method for providing short-circuit protection for the resistive AC load comprises the following steps of: turning on the active controlled switch within a first conduction angle range; obtaining the mean current value of the load through a current detection circuit; and determining whether the mean current value of the load is greater than a default value or not, wherein, if so, the active controlled switch is controlled to be turned off, and if not, the active controlled switch is controlled to be turned on. The invention also relates to a device and a switch for providing short-circuit protection for the resistive AC load. The method, the device and the switch for providing short-circuit protection for the resistive AC load, which are provided by the invention, have the advantages that: when the switch is required to be turned on, the switch is turned on first within the first conduction angle range which cannot cause damage to the switch and the circuit and then whether the switch is continued to be turned on or not is determined by determining whether the resistive AC load is subjected to a short circuit or not through the obtained current value; therefore, the switch and the circuit which are connected with the load can be protected while the resistive AC load in a short-circuit condition can be detected.

摘要： An ultrasound device is described. The ultrasound device may include a cavity, a membrane, and a sensing electrode. When an electrical signal is applied to the sensing electrode and a static bias is applied to the membrane, the membrane vibrates within the cavity and produces ultrasonic signals. The cavity, the membrane, and the sensing electrode may be considered a capacitive micromachined ultrasonic transducer (CMUT). The sensing electrode may be shaped as a ring, whereby the central portion of the sensing electrode is removed. Removal of the central portion of the sensing electrode may reduce the parasitic capacitance without substantially affecting the production of ultrasonic signals by the CMUT. This, in turn, can result in an increase in the signal-to-noise ratio (SNR) of the ultrasonic signals. The ultrasound device may further include a bond pad configured for wire bonding, and a trench electrically isolating the bond pad from the membrane.

摘要： A system and method for corrosion problems in magnetic media resulting from moisture penetrating through the carbon layer into the magnetic layer by diffusion or other methods are overcome by processing the carbon overcoat to stop and/or inhibit the moisture penetration. The process involves removing moisture channels from protective overcoats of thin film magnetic media by irradiating the protective overcoat with ultraviolet (UV) radiation in an inert hydrophobic chemical environment. Afterwards, the thin film magnetic media can be removed into ambient atmosphere where it is coated with a lubricant.
