    摘要: The present invention is a high power direct transmitter with frequency-shift keying (FSK) modulation. The transmitter implements a high power, high efficiency power voltage-controlled oscillator (VCO) which allows for production of a modulated RF signal at the final stage (ex.—right at the antenna), thereby eliminating all driving stage power amplification and frequency translation. The transmitter further provides a low SWAP-C alternative to currently available solutions.

    摘要: A fuel cell system is protected by monitoring at least one fuel cell parameter, comparing the parameter to a preset level, and disconnecting or reconnecting a main load in response to the fuel cell parameter. For example, a fuel cell system (300) is provided with a protection circuit (304, 308) that prevents operation of the fuel cells in the negative dP/dI region. System (300) includes a stack of fuel cells (302) connected in series and coupled to a main load (310). A controller (304) provides a control signal (314) based on the individual fuel cell voltage levels falling above or below a preset level. Control signal (314)is used to control a load switch (308)coupled between the stack of fuel cells (302) and the main load (310). The load switch (308) disconnects the main load (310) in order to prevent operation of the fuel cell cells in the negative dP/dI region.

    摘要: Before submitting a sample, including a first material layered upon a substrate, to an ion milling process, whereby a second material is sputtered onto the surface of the first material and the sample is then submitted to an etching process, an irregularity is formed on the surface of the first material. The overall process results in the formation of cones, or micro-tip structures, which may then be layered with a layer of low work function material, such as amorphous diamond. The irregularity in the surface of the first material may be formed by polishing, sandblasting, photolithography, or mechanical means such as scratching.

    摘要: A method for reducing charge accumulation in a field emission display (100) includes the steps of causing a plurality of electron emitters (114) to emit electrons (132) to reduce the potential at an anode (124) of the field emission display (100). Upon the reduction of the potential at the anode (124), the electrons (132) neutralize a positively electrostatically charged surface (129) of a spacer (130). The anode potential is dropped by providing a resistor (127) in series with a voltage source (126) connected to the anode (124). The anode potential is reduced by causing the electron emitters (114) to emit simultaneously to provide a pull-down current (128) at the anode (124). The voltage at the anode (124) is reduced to a value that causes a sufficient flux of electrons (132) to be attracted to the charged surfaces (129) for neutralizing them.
