摘要： An electronic circuit for converting higher-frequency output signals from a sensor into lower-frequency input signals for a discrete input wireless transmitter. The circuit includes a differential amplifier, a digital comparator, a digital frequency divider, and a transistor switch. The differential amplifier amplifies the sensor signals as a function of a frequency of the sensor signals. The digital comparator generates a square wave signal by comparing the amplified sensor signals to a fixed reference voltage. The digital frequency divider generates a lower-frequency signal by dividing the square wave signal. The transistor switch generates the lower-frequency input signals for the discrete input wireless transmitter by switching as a function of the lower-frequency signal from the digital frequency divider.

摘要： A pump for exchange of fluid between an apparatus reservoir and a reserve reservoir. The pump may have an elongated tubular body with a central bore with a reservoir end portion, an inlet end portion and an intermediate barrel portion. A piston assembly with a driving piston with a stem member with nonmagnetic properties attached and the stem member has a tubular extension member attached with all in longitudinal axis alignment slidably positioned in the central bore to position the driving piston adjacent to an electromagnetic coil assembly that is positioned around the intermediate barrel portion and to position the tubular extension member for a reservoir end to extend outwardly at the reservoir end portion opening. An output tubular member with a pressure relief valve is attached to an output port in a side wall of the reservoir end portion positioned for release of fluid through an output port.

摘要： Two pump oil level system and method for exchange of a fluid between an apparatus reservoir and a reserve reservoir. A first pump is connected to an apparatus reservoir to withdraw fluid to maintain a fluid level and to deliver fluid to a reserve reservoir. A second pump returns oil to the apparatus reservoir from the reserve reservoir. The first pump transfers fluid at a volume relatively larger than the second pump. The first and second pump flow conduits may have sensors installed to identify the fluid being pumped, such as air or oil, and a data processing device in communication with the sensors may evaluate fluid to determine system operation, and to estimate pump operating conditions and fluid viscosity in order to enhance pump flow by operation of heaters, and to verify correct maintenance of oil levels and that the reserve reservoir has oil. Data is suitable for transmitting.

摘要： A wireless field device for use in an industrial process includes input/output terminals configured to couple to a process interface element. A discrete input/output channel is configured to receive a discrete input from the process interface element through the input/output terminals when configured as a discrete input channel. The discrete input/output channel is further configured to provide a discrete output to the process interface element through the input/output terminals when the discrete input/output channel is configured as discrete output channel. Wireless communication circuitry is configured to transmit and receive information. A controller communicates information through the wireless communication circuitry and operates in accordance with configuration information to configure the input/output channel as an input channel when the input/output terminals are connected to a discrete process variable sensor, and further configure the discrete input/output channel as a discrete output channel when the input/output terminals are coupled to a discrete control element.

摘要： A towing pintle assembly 10 comprises a main body portion 18 attached by a flange 14 to the vehicle body. A hook 24 is pivotally coupled at its mid region to the main body by a pivot 22. To the upper end of the hook 24 is pivotally connected a locking lever 32. The locking lever may be swung between a locking position in which locking surfaces 34 thereon abut an abutment 36 to prevent opening of the hook and a free position in which the hook may open. The locking lever 32 may be moved to the free position either manually, or remotely by fluid-operated pistons 44. A frangible sheer pin 46 holds the locking lever in the locking position.

摘要： The invention provides novel methods and compositions for modulating gene function in plants. In particular, the invention provides methods and compositions that allow, for the first time, virus-induced gene silencing in rice. The invention is significant in that prior techniques were not available for rice and because of the major importance of rice to agriculture. The invention therefore provides techniques for the analysis of gene function in rice, as well as in other monocotyledonous species and dicotyledonous plant species.

摘要： A light pipe or illumination distributor of a backlit liquid crystal display panel in a hinge or tilt-up display for a laptop computer is coated with a highly reflective coating to control and eliminate the escape of light except through the front or exit face of the illumination distributor which is juxtaposed with the back side of a liquid crystal display panel. The highly reflective coating is further coated with a highly abrasion and shock resistant coating, such as an epoxy paint, to serve as the exterior of the computer display, thereby eliminating the need for a cover for the back of the display.
