摘要： A circuit and method are disclosed for protecting an integrated circuit (IC) against transient overvoltages. The circuit comprises a balun transformer and a normally-off transistor. The balun input terminals are connected to an unbalanced circuit, while the balun output terminals are connected to a balanced circuit. The transistor is connected between the balun output terminals and has a gate connected to ground or to some other reference voltage. When an overvoltage transient signal reaches the balun input terminals, the balun transformer converts the transient to a balanced transient signal on the two branches of the balanced circuit. During overvoltage conditions, one balun output terminal will have a voltage which swings low enough that the protection transistor turns on, effectively shorting the overvoltage spike and protecting any upstream (or downstream) IC components from damage. When the transient is over, the transistor returns to the “off” state.
摘要翻译：公开了用于保护集成电路（IC）免于瞬时过电压的电路和方法。该电路包括平衡不平衡变压器和常闭晶体管。平衡 - 不平衡转换器输入端子连接到不平衡电路，而平衡 - 不平衡变换器输出端子连接到平衡电路。晶体管连接在平衡 - 不平衡转换器输出端子之间，并具有连接到地或与其它参考电压相连的栅极。当过压瞬态信号到达平衡 - 不平衡变压器输入端子时，平衡 - 不平衡转换器将瞬变转换为平衡电路两个分支上的平衡瞬态信号。在过电压条件下，一个平衡 - 不平衡转换器的输出端子的电压将摆动得足够低，以保护晶体管导通，有效地短路过电压尖峰并保护任何上游（或下游）IC组件免受损坏。当瞬变结束时，晶体管返回到“关闭”状态。

摘要： The invention includes a method, and a component made according to the method having at least one thread pattern formed thereon from a stamping method. The invention includes a tubular member comprising a body having a wall formed from a wrapped sheet of stock to define an interior wall and an exterior wall, a seam in the wall defining a first and second end of the wrapped sheet of stock, and a thread pattern stamped on one of the interior and exterior wall. The method comprises the steps of forming a blank from sheet of stock having first and second opposing surfaces and at least a first and second edge. A thread pattern is formed onto at least one of the first and second opposing surfaces extending between the first and second edge while in a substantially sheet-like form. Following the formation of the thread pattern, the method includes bending the sheet stock into a tubular member such that the thread pattern on one of the first and second surfaces is substantially aligned about a circumference.

摘要： A distortion cancellation amplifier is described having a main amplifier and an error amplifier. The main amplifier, in response to an input signal, generates an output signal having an amplified signal component and a distortion signal component. The error amplifier is sized and biased to generate, in response to the same input signal, a distortion signal component that has substantially the same magnitude as the distortion signal component of the main amplifier. The distortion signal component from the error amplifier is subtracted from the output signal of the main amplifier.

摘要： A pet barrier that is placed in a motor vehicle to divide a portion of the interior of the vehicle from the remainder of the interior of the vehicle. The barrier can be removed when not used but can be quickly set up when needed. The barrier includes a telescoping support pole that has screens attached thereto. When the support pole is placed in the vehicle, such as by frictionally engaging the ends of the pole against the interior sides of the vehicle, the screens will divide the compartment so a pet can be confined behind the screens.

摘要： The invention features an exhalation assist device for adjusting the airway resistance in an exhalation circuit of a medical ventilator. The device includes a set of pressure, airflow and airway sensors, a controlling processor, a user interface, and a ventilatory unit in communication with a medical ventilator. Data relating to pressure within the ventilatory unit and data relating to exhalation airflow, exhalation circuit pressure and exhalation circuit resistance are provided to the controlling processor by the sensors. The controlling processor compares measured and calculated values for airway pressure, airflow, airway resistance and applied negative pressure with desired values that have been entered by a clinician. Based on these calculations, the controlling processor transmits a signal that will change the applied negative pressure applied to the exhalation circuit by the ventilatory unit. The amount of negative pressure applied during the breathing cycle is varied by the controlling processor so that the amount of exhalation assist increases proportionately with the amount of exhalation flow and so that the amount of pressure within the patient airway remains constant at a level greater that zero and less than PEEP.

摘要： Container package for transporting a plurality of silicon wafers for shipment as well as preventing contamination thereof. The wafer container package includes a wafer cassette having two sides, a configured end, and an H bar end including an upper and lower ramp support with the bar being reinforced by a partially cylindrical rod; a package bottom including four sides, an edge surrounding the sides, hook latches, four internal side dividing members and a flat bottom; and a package top including four sides, a lip to encompass the edge, configured independent opposing flexible grooved members, and recessed top surface for stacking where the cassette is positioned by internal side dividers in the package tops and bottoms for secure placement. The three components provide that the cassette mates between the package tops and bottoms, the wafers mate in the cassette and with the top opposing members, the package tops and bottoms mate between the trough, and the hook ends secure the package tops and bottoms together and also secure the cassette and wafers therein. The sides of the package are smooth, providing for a flush perimeter for taping. The recessed top surface provides for stacking of like packages. The smooth, rounded contour design of the package provides a package design for shrink wrapping. The package limits and prohibits wafer movement and eliminates wafer breakage.
