Title: Cytological specimen analysis system with prescreening and generation of viewing path information
Inventor: OLSSON LARS J
IPC: G01N15/14
Filed: 1997-10-24
Abstract: A cytological specimen analyzer includes an image capture apparatus, a mapper and a screening station. The mapper receives digital images of regions of a slide containing a cytological specimen and determines if each of the regions contains cytological material. The mapper analyzes the image of each region, pixel by pixel, and if the region contains cytological material then the coordinates of the region are stored along with a focal position for the region and a value indicative of the amount of cytological material in the region. Upon analysis of each region on the slide, the mapper determines the most efficient path to be traveled between regions containing cytological material to minimize the viewing time of an operator at the screening station. Upon request by the screening station, the sequence of the aforesaid coordinates, which is indicative of the most efficient path, are transmitted to the screening station.

Title: Passive optical telecommunication system employing multiple wavelength source and plural power splitting stages
Inventor: STARK JASON BLAIN
IPC: H04B10/272
Filed: 1998-01-19
Abstract: A unique time slot is assigned to each of a plurality of wavelengths emitted by a single, centralized wavelength division multiplexed optical source to provide a "bit interleaved" WDM signal. In accordance with an illustrative embodiment of the present invention, the thus-developed bit-interleaved WDM signal is replicated in cascaded stages of amplification and power splitting before data is encoded for respective frequency dependent receivers as, for example, a plurality of passive optical networks. Because the output of the optical source need not be encoded with data for the respective receivers until after many stages of splitting and amplification, a small number of time division multiplexing (TDM) modulators synchronized to the source may be used to deliver data to potentially tens of thousands of subscribers.

Patent CA-2234949-A1 (CA)
Inventor: SCHNETZKA HAROLD R
IPC: H02P1/42
Filed: 1998-04-16
Abstract: A motor starter circuit for minimizing the amount of current drawn by the motor from a power source during starting of the motor through current transformation achieved by selectively controlling actuation of a plurality of high speed switches. The circuit is for use with a alternating current power source that provides positive and negative voltage alternations, and an alternating current motor. The motor starter circuit comprises a first bidirectional switch through which line current from the power source is provided to the motor, and a pair of switch-diode combinations electrically configured to carry the current in the motor when the bidirectional switch, which is controlled to cycle between an open and a closed position, is in an open position. Actuation of the pair of switch-diode combinations is controlled based on the polarity of the motor current alternation. The resulting current transformation minimizes the current drawn by the motor during starting, and enables equalized input volt-amp product and output volt-amp product. The starting current drawn is reduced from the available line current in proportion to the duty cycle of the bidirectional switch.
