Abstract: A circuit design incorporates charge compensation devices within a Track-and-Hold (T/H) circuit to control channel charge generated by a tracking switch. Calibrating a T/H circuit requires selecting charge compensation devices from an array of similar devices to function within the T/H circuit to absorb charge ejected from the tracking switch. The charge compensation devices can also be pseudorandomly selected to operate within the T/H circuit. Charge compensation devices are used to enhance the performance of bottom-plate sampling systems as well as bootstrapped T/H circuits.

Abstract: Location of an emitter using leaky cables. A two-channel receiver determines the location of an emitter by measuring the phase and/or amplitude difference between emitter signals received by leaky cables. In one embodiment, two leaky cables having different propagation velocities are used. In a second embodiment also suitable for use with fiber optic cables, two cables having the same propagation velocity are used, but have different lengths, the extra length being taken up by serpentine patterns or loops. A single cable in a loop may also be used. The leak points on the cables may be passive, or may be controlled RF switches.

Abstract: A wireless coverage mapping technique is arranged to display the signaling location for each measured signal as well as the measured signal strength. In one embodiment, the resulting map contains a colored circle at the point where the signal measurement is taken and a line connecting the circle to the signaling location in communication with the location of the measurement at the time the measurement is taken. If desired, the color of the line can reflect the connectively metric while the style of the line can convey other information about the measurement or the measurement type. Also, if desired, the direction of movement of a mobile detector (for example, a cellular phone) can be displayed. The map can be used, for example, to determine neighbor lists such that by observation the administrator can match the neighbor list for a particular connection against the transmitter actually selected for that transmission.

Abstract: A switching pre-regulator for a bulk capacitor filter followed by a series pass regulator has a switching element controller that relies upon a large desirable leakage inductance in a main secondary winding of a power transformer acting as a swinging choke input to the bulk capacitive filter. This desirable leakage inductance limits inrush current and supplies some filtering. However, the effective value of the swinging choke is a function of load conditions, and introduces a varying phase shift that would potentially disturb the zero crossing detection used in properly activating the switching element.

Abstract: A method of evaluating for the presence of a target polynucleotide in a sample, using an addressable array of multiple polynucleotide probes linked to a substrate. The sample is exposed to the array and a set of polynucleotide target probes, such that target polynucleotide which may be present will bind to a predetermined feature of the array through multiple target probes of the set by forming at respective target regions on a target molecule, simultaneous hybrids with anti-target regions of the multiple target probes. A binding pattern on the array is observed and the presence of the target polynucleotide evaluated based on the observed binding pattern. Kits using such arrays, and methods for selecting target probes are further provided.
