Abstract: An analog-to-digital converter (ADC) circuit comprising two time-interleaved successive approximation register (SAR) ADCs. Each of the two time-interleaved SAR ADCs comprises a first stage SAR sub-ADC, a residue amplifier, a second stage SAR sub-ADC and a digital error correction logic. The residue amplifier is shared between the time-interleaved paths, has a reduced gain and operates in sub-threshold to achieve power effective design.

Abstract: Neutrophil elastase (NE) is a protease secreted by neutrophils during inflammation. Aberrant expression of NE such as in chronic respiratory inflammatory diseases, results in tissue destruction and decline in lung function. Compositions including an NE-targeting agent that targets the pathologic elements of respiratory inflammation are provided. Non-anticoagulant heparin derivatives or fragments are exemplary NE-targeting agents. The compositions preferably include a carrier, such as chitosan, to facilitate delivery of the active agent. Methods of manufacturing non-anticoagulant heparin are also provided. Methods of administering the disclosed compositions to treat respiratory diseases are also disclosed. In preferred methods, an effective amount of the pharmaceutical composition is administered to subject in need thereof to reduce, inhibit, or alleviate one or more symptoms of chronic respiratory inflammation.

The metal detector has a phase shift circuit to phase shifting a sensor output signal by a known amount and a switch operating in synchronization with an excitation signal of the sensor for sampling the amplitude of the phase shifted output signal.

Abstract: A canopy lighting device comprising a body having a light source and a base that magnetically couples to the body. The body and the base can be located on opposite sides of a fabric sheet to magnetically clamp the lighting device to the fabric sheet. The base may have an energy source, first electrical connection features coupled electrically to the energy source, and first magnetic connection features. The body may have a light source, second magnetic connection features for cooperating with the first magnetic connection features to clamp the body to the bases and second electrical connection features. The second electrical connection features cooperate with the first electrical connection features of the base when the body and the base are clamped together.

Abstract: A sensing device having a sensing surface for placing against a wall for detecting objects behind a wall lining has first and second sensors, each sensor including at least first and second capacitor plates and associated resistors forming RC circuits having time constants dependent on the adjacent wall material. Detection circuits connected to the RC circuits provide first and second voltage signals having amplitudes dependent on capacitance changes. A processor effects a comparison of the first and second voltage signals, and compares them to establish the magnitude of the voltage difference between the voltage signals, indicating a detected object center position when the difference signal is less than a predetermined value.

Abstract: A multiple sensitivity stud sensing device for determining a location of objects behind a wall lining has a housing with a surface for moving over the wall lining. Within the housing are a capacitive sensor with first and second capacitances located adjacent the surface and control circuitry. The control circuitry includes a detecting circuit connected to the sensor for providing a detection signal related to an imbalance between the first and second capacitances, and a processor for receiving the detection signals and providing a display signal. A display is located on the housing for indicating location of an object behind the wall lining. The processor compares a detection signal to stored predetermined threshold values of detection signals associated with different wall lining thicknesses and displays a thickness value to the user.
