摘要:
A system (10) is disclosed for use in detecting and analyzing cell and tissue microstructure as part of the diagnosis of a variety of pathological conditions, including cataracts, as well as aging, disease and certain traumatic events. The system includes a data input system (12), which may produce data regarding the microstructure to be evaluated either invasively or noninvasively. An electron microscope (20) may be employed to collect data regarding the microstructure of any tissue to be evaluated for the existence of a pathological condition. The system (12) also includes a computer (14) programmed to analyze the output of the data collection system by using signal processing techniques that are applicable to the data output characterizing the nonrandom microstructure. These techniques include fractal analysis, oscillatory analysis, and a modified Fourier/fractal analysis. The outcome of the signal processing is then compared to empirical data to effect a diagnosis.

An anti-energy diversion system for mounting underneath the cover of a standard electric utility meter in order to sense common meter tampering events and indicate the occurrence of such events. A non-battery energy storage circuit extracts energy from the AC power line available in the meter to power the system even during power outages. A flashbulb associated with a heat sensitive indelible indicator is coupled to the energy storage circuit when any one of several tamper event sensor switches are closed. When a tamper event is sensed, a brilliant flash of light is discharged and the appearance of the indelible indicator is transformed.

A postage meter printing apparatus for applying postage indicia to a mailpiece having a cyclically operating drum for feeding the mailpiece through the postage meter. The periphery of the drum has an aperture therein. Structure is provided for maintaining the mailpiece against the drum as the mailpiece is fed by the drum and for cycling the drum at a low rotational speed during a part of the cycle when a low-speed printing process is taking place and high rotational speeds during a higher speed printing process and of the remainder of the cycle thereby providing means for obtaining maximum overall cycle speeds while accommodating the low-speed requirements of the slower printing process. A matrix print head for the low-speed process is located internal to the drum having a printing position and a non-printing position, the print head is automatically placed adjacent the mailpiece through the aperture in the drum to its printing position when the aperture is between the print head and mailpiece. Structure is also provided to activate the print head when it is in its printing position.

A postage meter printing apparatus for applying postage indicia to a mailpiece having a cyclically operating drum for feeding the mailpiece through the postage meter. The periphery of the drum has an aperture therein. Structure is provided to maintain the mailpiece against the drum as the mailpiece is fed by the drum and to cycle the drum. A matrix print head located internal to the drum has a printing position and non-printing position. The print head is automatically placed adjacent the mailpiece through the aperture in the drum to its printing position, when the aperture is between the print head and the mailpiece. The print head is a matrix print head of impact or other type and includes a cooperating ribbon either inked or other to print on the mailpiece. The inked ribbon is contained in a replaceable cartridge. Structure is provided to activate the print head when it is in its printing position. The circumference of the drum may be fitted with a letterpress printing plate to allow simultaneous matrix printing of variable data and conventional rotary letterpress printing of repetitive data.
摘要:
A value selection system for a postage meter includes a plurality of print wheels rotatably mounted within a print drum. The print drum is coupled to be driven to rotate such that selected print elements on each of the print wheels are moved to imprint a postage value on a mail piece or other postage imprint receiving surface. The print wheels are selectively positioned by a print wheel value selection mechanism which is operable to set the print wheels during any time within a printing cycle except when the actual imprint is being impressed. The mechanism is operable to move the print wheels when the print drum is at rest and when the print drum is in motion. The position of the print wheels and the print drum may be monitored to account for the printing of postage by the meter.
