Title: System for extracting bodily fluid and monitoring an analyte therein
Inventor: RACCHINI JOEL
IPC: A61B5/1473
Filed: 2004-06-07
Abstract: A system for extracting a bodily fluid sample (e.g., an interstitial fluid [ISF] sample) and monitoring an analyte therein includes a disposable cartridge and a local controller module. The disposable cartridge includes a sampling module adapted to extract a bodily fluid sample and an analysis module adapted to measure an analyte (e.g., glucose) in the bodily fluid sample. The local controller module is in electronic communication with the disposable cartridge and is adapted to receive and store measurement data from the analysis module. An ISF extraction device includes a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting an ISF sample therefrom. The device also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The device is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner whereby an ISF glucose lag of the ISF sample extracted by the penetration member is mitigated. A method for extracting ISF includes providing an ISF fluid extraction device with a penetration member and a pressure ring(s). Next, a user's skin layer is contacted by the pressure ring(s) and penetrated by the penetration member. An ISF sample is then extracted from the user's skin layer while pressure is being applied in an oscillating manner by the pressure ring(s). The oscillating pressure mitigates an ISF glucose lag of the extracted ISF sample.

Title: Catalyst for purifying exhaust gases and process for producing the same
Inventor: MIYAKE YOSHIHARU
IPC: B01J21/06
Filed: 2004-02-09
Abstract: With respect to an oxide powder having a characteristic that a suspension suspending the oxide powder in pure water exhibits a pH value of 7 or less, a noble metal is loaded on the oxide powder by using a noble metal salt solution exhibiting a pH value lower than the pH value of the suspension in order to inhibit the granular growth of loaded noble metal particles at high temperatures. It is believed that the affinity enlarges between noble metal particles, generated by the decomposition of the noble metal salt, and the oxide powder because no coarse noble metal particles are generated by neutralizing the noble metal salt so that the binding force enlarges between the oxide powder and the noble metal salt.

Title: Direct digital frequency synthesizer for cellular wireless communication systems based on fast frequency-hopped spread spectrum technology
Inventor: REPIN ALEXANDER
IPC: H03L7/00
Filed: 2004-02-18
Abstract: Direct digital frequency synthesizer (DDFS) are used for generating an oscillator signal (s (t)) with an approximately sinusoidal waveshape and can advantageously be applied to wireless RF transceivers in a cellular communication system based on a fast frequencyhopped spread spectrum (FHSS) technology. The invention particularly refers to a method for reducing spurious harmonics, voltage and/or current glitches in the frequency synthe sizer's noise power density spectrum (Phiee (kf)) caused by phase truncation, amplitude and time quantization errors introducing fitter into the waveform of the output signal (s (t)). Thereby, discrete P-bit phase difference values (DeltaPhis(nT)) serving as frequency control words (FCWs) are repeatedly accumulated to generate P'-bit samples of a digital sawtooth signal (Phis(nT)) with a predefined time period (N.T), which are then submitted to a phase-to sine-amplitude conversion of the obtained discrete phase input values (Phis(nT)) into a set of discrete sine amplitude sample values (s(nT)). After that, these sine amplitude sample values (s(nT)) are converted into an approximation of a quantized analog sine wave (a1' (t)). According to one embodiment of the underlying invention, spurious harmonics (DSCs) are spread over the entire signal spectrum by adding a P"-bit number word representation of a random number (e( nT)) to the obtained sine amplitude sample values (s(t)). Thus, the periodical structure of glitches, phase truncation and quantization errors (e(nT)) of the approximated sine wave (s (t)) is destroyed and its spurious discrete noise power density spectrum (Phi ee (kf)) caused by said error signal (e (nT)) is transformed into a broadband continuous noise power density spectrum (Phiee (f)). Finally, the additive noise is compensated by subtracting a digital-to-analog converted representation of said random number (r(nT)) from the quantized analog sine wave approximation (a 1'(t)) at the analog output port of the direct digital frequency synthesizing unit (DDFS).
