Abstract: A method of providing accurate position, navigation, and timing information comprising the steps of providing at least four transceiver devices, providing an auxiliary GPS device, and providing a receiver GPS device. Each transceiver devices receives a plurality of GPS signals from a plurality of GPS satellites, and calculates a transceiver position and transceiver velocity vector. The transceiver position, transceiver velocity vector, and GPS signal are repackaged at each transceiver into a first spread signal structure, which is transmitted from each transceiver as a first GPS-like signal. The GPS-like signal is received at an auxiliary GPS device, which generates a simulated GPS signal. This simulated GPS signal is then output and received by a simulated GPS device.

Abstract: A device for detecting frequency modulated continuous wave radar includes an antenna connected to a bandpass filter. The antenna is configured to receive frequency modulated continuous wave (FMCW) pulses within a predetermined frequency range. A frequency mixer is connected to the bandpass filter and a synthesizer and is configured to mix a signal from the synthesizer with an output of the bandpass filter to produce basebanded data. A high-pass filter is configured to isolate short pulses pertaining to the basebanded data, and a low-pass filter is configured to isolate long pulses pertaining to the basebanded data. A microprocessor is configured to set thresholds for comparison with the outputs of the high-pass filter and the low-pass filter.

Abstract: Methods and systems for collecting cells on a filter disposed in a specimen fluid containing suspended cells of a biological specimen. A short vacuum pulse is applied across a filter to sip specimen fluid. A percentage or portion of the filter surface area covered by cells is determined is representative of or correlates to the density of cells in the specimen fluid. A maximum vacuum amplitude and/or duration are determined utilizing the determined filter coverage. A longer, continuous vacuum or slurp is applied across the filter to collect cells on the filter while limiting the amplitude and/or duration of the slurp based at least in part upon the determined maximum vacuum amplitude and/or duration.

Abstract: Method and system for imaging and analyzing a biological specimen on a specimen carrier, such as a slide. One or more imagers acquire images of a biological specimen on a slide and generate electronic image data. One or more analysis computers, such as a cluster of analysis computers, are connected to the imagers through a network and process the electronic image data. The number of analysis computers can be different than the number of imagers, and analysis computers can be located remotely from the imagers. The results of processing by the analysis computers are stored to a database, which is accessible by one or more review stations.

Abstract: First and second images of respective portions of a cytological specimen are acquired at different brightness levels.

Abstract: System for simultaneously imaging multiple biological specimens on a single, translatable stage of an imaging system. The stage supports multiple specimen carriers, such as slides, which carry biological specimens. When the stage is at a first location, a first image acquisition component takes an image of a first portion of a first specimen, and a second image acquisition component takes an image of a first portion of second specimen. The stage is moved from the first location to a second location, thereby moving the slides and specimens carried thereby in the same direction and by the same amount. At the second location, the first acquisition component takes an image of a second portion of the first specimen, and the second acquisition component acquires an image of a second portion of a second specimen. Lenses of acquisition components are independently adjustable for independent focusing by acquisition components.
