    摘要: A pulsed plasma thruster (PPT) and a method of making the PPT are disclosed. The PPT includes no moving parts and can be made in a small size. The PPT can achieve long operating duration by using vapor as a fuel. Liquid used to form the vapor can be easily stored and can provide an ample supply of vapor. The PPT is also designed to facilitate easy and rapid manufacture. The process for making the PPT uses known techniques for making printed circuit board devices.

    摘要: A pressure sensor for detecting an electric arc in an electrical switchboard, the sensor being in an enclosed case containing a conical opening, the case being placed in the switchboard. A pressure switch in the sensor is attached to the interior of the case and is electrically connected to a circuit board for transmitting a signal when a contact in the pressure switch is closed. When a pressure wave created by the electric arc enters the case through the conical opening it forces a contact on the pressure switch to close thereby completing a circuit with the circuit board which transmits the signal to, for example, a central processor, to turn off the source of electricity thereby quenching the electric arc.

    摘要: An arc flash detection system includes a sensor for determining and responding to the presence of an arc flash condition in electrical equipment by detecting a pressure rise, rate of pressure rise and/or ultraviolet radiation characteristic of an arc flash, and generating a signal in response thereto; and processing means responsive to said signal for operating a protective system to de-energize the electrical equipment within a period of time of sufficiently short duration to prevent a pressure wave from the arc flash from causing unacceptable darn age to equipment or personnel.

    摘要: The present invention is directed to an enhanced sampling device, herein referred to as an ESD, for enhancing the collection efficiency of the SPME method by enhancing the flow of the analytes onto the sampling fiber. The ESD includes a tubular main body, used for a sampling shroud, which directs a flow of analytes to contact the fiber during collection. One end of the main body is open and faces the sample, allowing analytes to flow into the ESD and contact the fiber. A second piece of tubing branches from the other end of the main body and becomes an outlet port, possibly leading to a pump. The ESD permits more rapid transport and absorption of the analytes to the fiber for collection.

    摘要: A method and device are provided for manipulating high-speed flows without moving aerodynamic structures. More particularly, a flow control actuator device is provided that is capable of producing a pulsating synthetic jet with high exhaust velocities for manipulating high-speed flows without moving aerodynamic structures. The high exhaust velocities of the actuator device may reach sonic levels of Mach 1 or greater. In one embodiment, the device may be constructed as an array of devices. In such an embodiment, each individual device is preferably reduced to a very small size. In such an embodiment, each individual device can then be fired in temporal patterns to create high-speed synthetic jets of air extending above the surface of the each device.
