Abstract: A multi-frequency ultrasonic liquid level gauging system 30 includes a storage apparatus 34 for storing a volume of liquid 32 and a plurality of ultrasonic transducers 36a-d. Each transducer introduces a distinct ultrasonic signal into the storage apparatus 34 and receives a reflected signal back. A circuit 40 drives and receives signals from the ultrasonic transducers. a processor calculates the liquid level at each of the locations of ultrasonic transducers 36a-d based on the reflected signal received from each transducer. the transducers 36a-d are connected in parallel, thereby allowing the circuit 40 to communicate to the transducers through a single conductive path. A method of measuring a liquid level in the storage apparatus 34 includes emitting a single drive signal to the plurality of ultrasonic signal sources 36a-d, wherein each source is operable to transmit ultrasonic signals having unique frequencies. The ultrasonic signals are transmitted through the liquid 32 and each is reflected at the liquid surface 44. The reflected signals also have unique frequencies and are communicated to a processor. The reflected signals are distinguished and the depth of the liquid level at various storage apparatus locations is calculated from each of the distinguished reflected signals. The depth of the liquid 32 is a function of the propagation time of each signal through the liquid.

Abstract: A high Q bandpass filter (102) is tuned by applying a
transient (204) to the filter to cause it to ring. The ringing
of the filter produces an output damped oscillatory waveform
(206) whose zero crossings (208) are converted to a pulse train
(210) and counted in a digital counter (112) to a predetermined
number n. The output (214) of the counter is compared to an
accurate timing signal (216) which has a time duration equal to
the time of n pulses when the filter is accurately tuned. The
output of the comparator (118) is applied to an integrator (122)
to generate a control signal V c  to tune the filter. The high
frequency tuning problem is thus converted to a low frequency,
time domain problem which is readily implemented.

reproduction circuit (1) includes: a waveform equalization block (10) for
waveform-equalizing a regenerative signal, a binarization block (20) for
binarizing the waveform-equalized regenerative signal, a synchronous clock
reproduction block (30) for generating a synchronous clock from the binarized
signal, and a waveform equalization control block (40) for controlling a transfer
function of the waveform equalization block (10) according to a jitter
component between the synchronous clock and the binarized signal. The

signal between the binarized signal and the synchronous signal so as to obtain
an optimal value of the transfer function of the waveform equalization block
(10) by using a microcomputer, for example. The transfer function is
controlled so as to reduce the jitter component of the synchronous clock.

Abstract: Methods for treating vascular conditions associated with localized imbalance in vascular tone, which are hypothesized to be largely due to elevated endothelin (ET) are provided. The methods involve administration of nitric oxide (NO), agents which are able to provide NO, such as NO donors, agents which activate guanyl cyclase, such as YC-1, or agents which prolong the actions of endogenous NO or cyclic guanosine monophosphate (cGMP; a 2nd messenger molecule), such as phosphodiesterase (PDE) inhibitors. According to the invention, such agents are administered in minimal doses or microdoses by any route known in the art, so as to provide dosages which are about one half to about one twentieth (½ to 1/20) of those known to induce vasodilation in "normal" circulations. The low doses of these agents effectively alleviate vascular conditions associated with a reduction in NO production or an attenuation of NO effect, by restoring balance in vascular tone while exerting almost no systemic effect in normal vasculature.
