Abstract: A method for data transfer for various applications between a on board unit (OBU), which comprises a processor, memory means and at least one interface to an external entitiy. A sequence of commands is exchanged over the interface and processed by the OBU in order to perform the respective task according to the application of the OBU and/or the external entity. The system for data transfer comprises a macro interpreter in the OBU to receive and interpret the macros from one of its interfaces.

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.

Abstract: Log processing apparatus comprises a cutting machine that defines a substantially vertical cutting plane, feed mechanism that feeds a log through the cutting machine in substantially lengthwise horizontal motion parallel to the cutting plane, a measuring station spaced horizontally and vertically from the cutting machine, and transfer mechanism by which a log is carried in horizontal translatory motion from the measuring station to the feed mechanism. At the measuring station, or before the log reaches that station, it is established in an optimum rotational orientation which is thereafter maintained through transfer of support of the log to a set of jaws on the feed mechanism. At the measuring station a relationship is ascertained between a calculated plane that extends lengthwise in the log and a reference plane defined at the measuring station that has a fixed relationship to the cutting plane.
