Abstract: An electrocardiogram (ECG) processor is disclosed. The ECG processor includes ECG sampling circuitry configured in a first mode to acquire a continuous ECG sample set from an ECG signal by digitally sampling the ECG signal at a Nyquist rate for a first predetermined number of heartbeats and in a second mode to acquire a non-continuous ECG sample set from the ECG signal for a second predetermined number of heartbeats by digitally sampling active regions of the ECG signal that contain a PQRST complex and not from silent regions between adjacent PQRST complexes. The ECG processor also includes processing circuitry configured to determine from the continuous ECG sample set relative locations of the active regions and provide the relative locations of the active regions to the ECG sampling circuitry for sampling the ECG signal in the second mode.

Abstract: Structures for a waveguide crossing and methods of fabricating a structure for a waveguide crossing. A waveguide crossing includes a central section and an arm positioned between a waveguide core and the central section. The arm and the waveguide core are aligned along a longitudinal axis. The arm is coupled to the waveguide core at a first interface, and the arm is coupled to a portion of the central section at a second interface. The arm has a first width at the first interface, a second width at the second interface, and a third width between the first interface and the second interface. The third width is greater than either the first width or the second width.

Abstract: A glucose sensor includes an insulating metal oxide layer and at least one pair of metallic electrodes arranged on the insulating metal oxide layer and separated by a gap containing the metal oxide layer. In operation, a probe including a voltage supply and current sensor can provide a voltage difference across the first and second metallic electrodes while a sample is present across the gap between the electrodes. A measured current between the first and second metallic electrodes when the voltage difference is provided can be correlated to a glucose level of the sample.

Abstract: Sono-chemical reactors and methods of using the same are provided. The sono-chemical reactors may include a plurality of sections that are sequentially connected along a longitudinal direction of the sono-chemical reactor. The plurality of sections may include a sono-reactor section that includes a reactant inlet through which reactants are supplied into the sono-reactor section and a static mixer section that is configured to receive a first reactant/product mixture from the sono-reactor section and is configured mix the first reactant/product mixture therein for reaction between unreacted reactants. An inner space of the sono-reactor section may taper along the longitudinal direction of the chemical reactor away from the reactant inlet. The plurality of sections may also include a product separation section that is configured to receive a second reactant/product mixture from the static mixer section and is configured to separate a product from the second reactant/product mixture.

Abstract: The present invention discloses imaging antenna and array by designing the system in the Ultra-high frequency (UHF) band 300 MHz-3 GHz with resolution comparable to high-frequency microwave imagers (i.e., super-resolution). To obtain high resolution at relatively low system cost and complexity, a novel modulated antenna array element design is disclosed. The antenna is basically small loop loaded with spiral resonator. The selection of the SR as a resonator provides for adequate miniaturization rate at the lower end of the microwave frequency range. A non-modulated version of this antenna has been conceived and yielded a resolution comparable to the 24 GHz antennas while operating at 426 MHz. The disclosed antenna element operating at 426 MHz produced images with very comparable attributes to the one obtained at 24 GHz. In fact, it has been established that proposed antenna element yield a resolution of around 5 mm (much less that the wavelength divided by 100), and hence it provides super-resolution as long as the diffraction limit is concerned. The present invention further discloses an imaging probe unit comprising a imaging sensor loaded with a PIN diode, an L-matching circuit and an LC resonant detuning circuit. The present invention further discloses a one-dimensional array, comprising a plurality of imaging probe units which are placed side by side in very close proximity of each other.
