摘要： Several push-pull linear hybrid class H amplifiers are disclosed. A split power rail provides a positive supply rail and a negative supply rail in response to a power supply control voltage. A push-pull amplifier stage is powered by the positive and negative supply rails. The amplifier stage receives an input signal and provides a corresponding amplified output signal. A power supply control circuit provides the power supply control voltage in response to the smaller of the positive and negative supply rails, and the input signal.

摘要： A liquid sample to be analyzed is fed to a micro pump. The pump directs the solution, as a stream of uniformly sized and spaced droplets, into a laminarly flowing stream of hot carrier gas. The carrier gas evaporates the solvents (e.g. water) in the droplets to form a stream of dried particles. The particles are vaporized by a plasma, laser or other heat source. The vapour can be ionized and the ions analyzed by a mass spectrometer, or the vapour can be analyzed by optical spectroscopy. The method reduces oxide and other interference effects, increases sample utilization, and reduces waste, signal noise, and memory effects, increasing instrument productivity. Multiple nozzles can be used to change samples or to shoot calibrating droplets, further increasing productivity. Signal detection can be synchronized with droplet firing, or the signal, which is intrinsically modulated at the drop frequency, can be band pass filtered and synchronously detected, to increase the signal to noise ratio. The dried particles can also be directed into a vacuum chamber and deposited in a desired pattern on a surface in the vacuum, thus delivering controlled microdosages of material onto the surface.

摘要： In a mass spectrometer system, ions travel through an orifice in an inlet plate into a first vacuum chamber containing AC-only rods, and then through an orifice into a second vacuum chamber containing a standard quadrupole. The second vacuum chamber is held at low pressure, e.g. 0.02 millitorr or less, but the product of the pressure in the first chamber times the length of the AC-only rods is held above 2.25.times.10.sup.-2 torr cm, preferably between 6.times.10.sup.-2 and 15.times.10.sup.-2 torr cm, and the DC voltage between the inlet plate and the AC-only rods is kept low, e.g. between 1 and 30 volts, preferably between 1 and 10 volts. This produces a large enhancement in ion signal, with less focussing aberration and better sensitivity at high masses, and also allows the use of smaller, cheaper pumps so the system can be more easily transportable.

摘要： This invention relates to acoustic drivers with stationary and moving coils. Time varying signals are applied to the moving and stationary coils to control the movement of a diaphragm, which produces audible sound. The time varying signals correspond to an input audio signal such that the sound corresponds to the input audio signal. Some of the described embodiments include multiple moving coils, multiple stationary coils or both. Some embodiments include feedback for adjusting one or more of the signals based on a characteristic of the acoustic driver. Various compensation and other features of the invention are also described in relation to various embodiments.
