Abstract: A security system including a main control unit, a plurality of sensors and a user interface device. The main control unit communicates with a remote central monitoring station when a sensor detects an alarm event. Once the communication signal from the main control unit is successfully transmitted to the central station, a siren is sounded. Thus, the delay time to trigger the siren is dynamic based on the time it takes for successful transmission of an alarm notification to the central station. This dynamic delay accounts for transmission interruptions between the security system and the central station and allows the location of the main unit and/or the siren from being detected prior to successful alarm transmission to the central station.

The main control unit communicates with a remote central monitoring station, when a sensor detects an alarm event. Once the communication signal from the main control unit is successfully transmitted to the central station, a siren is sounded. Thus, the delay time to trigger the siren is dynamic based on the time it takes for successful transmission of an alarm notification to the central station. This dynamic delay accounts for transmission interruptions between the security system, and the central station and allows the location of the main unit and/or the siren from being detected prior to successful, alarm transmission, to the central station.

Abstract: The invention provides compositions and methods for use in delivering a substance of interest to a targeted cell. The substance of interest is associated with a targeting fragment of a toxin molecule or a lectin that specifically binds to a cell surface receptor, such as the B subunit of an A/B type toxin molecule. The substance of interest may be a photosensitizing agent, in which case the cell (e.g. a cancer cell) may be killed by exposure to light after delivery of the agent. Alternatively, the substance of interest may be a visualizing agent that enhances visualization of the targeted cell.

Abstract: An optical scanning holography system which requires only a two dimensional scan to record three dimensional information from a fluorescent specimen wherein the optical scanning holography is based on scanning the specimen with a Fresnel zone pattern and detecting and decoding the fluorescent light reflected from the specimen. The flourescent light reflected from the specimen contains three dimensional information about the specimen so that once the fluorescent light is detected and decoded a three dimensional image of the specimen can be obtained and displayed using only the two dimensional scan.
