Abstract: ABSTRACT    This invention relates to a method for the detec-tion of an analyte which generates hydrogen peroxide in the presence of a suitable oxidase in saliva which comprises contacting the saliva with a reagent system comprising an oxidase selective for the analyte, for example glucose, lactic acid, galactose or ethanol, to be detected, a peroxidatively active material and a redox indicator said indicator being selected from those indicators which have an oxidation potential, for example less than 0.54, which is sufficiently low to resist reduction by reducing agents present in the saliva.
Patent CA-2084925-A1 (CA)
Inventor: DITTMER TIMOTHY W
IPC: H03F1/52
Filed: 1992-12-09
Abstract: An AC power amplifier is disclosed for amplifying an AC input signal while limiting the current drawn by the amplifier. The amplifier includes at least one transistor having an input circuit for receiving an AC input signal as well as a DC bias voltage and an output circuit connected to the DC voltage source for drawing current therefrom during conductive periods of the transistor. The transistor exhibits the characteristic of being non-conductive when the AC input signal together with the DC bias voltage are less positive than a DC threshold voltage level and is conductive when the AC input signal and the DC bias voltage are together more positive than the DC threshold voltage level whereupon DC current is drawn by the output circuit from the DC voltage source. The DC current is sensed and a sense signal is provided having a magnitude in accordance therewith. The sense signal is compared with a reference current level and a control signal is provided having a value which varies as a function of the comparison. The control signal is decreased in magnitude when the sense current exceeds the reference current level . The DC bias voltage is then decreased to thereby decrease the conductivity of the transistor and thereby limit the magnitude of the DC current to that of the reference current level.

Inventor: POWELL WILLIAM E
IPC: H03L7/23
Filed: 1994-06-08
Abstract: Digital signal processing techniques are used to synthesize a range of output frequencies locked to a non-pullable reference oscillator, and the synthesized output frequency is used in a slave low bandwidth phase-looked loop; by increasing digital resolution in a phase accumulation register, any desired resolution of output frequencies can be generated. The range of output frequencies is synthesized in such a way as to generate only high-frequency fitter, which can be easily filtered by follow-on, low-cost, relatively high bandwidth phase-locked loops which are typically needed for frequency multiplication in a given system. The magnitude of residual fitter is easily controlled by proper choice of the non-pullable oscillator reference frequency, the output frequency range to be synthesized and various other digital factors, such as divider ratios. Improved noise performance is achieved while still maintaining a wide pulling range of the composite phase-locked loop.
