The evacuation system also includes a filter having a second read/write device for transmitting information to the first read/write device. A microcontroller, which is in functional communication with the first read/write device and the operational component, interprets the information received by said first read/write device and controls the operational component based on said interpreted information.
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS The present application is a continuation of U.S. patent application Ser. No. 11/398,285, filed Apr. 4, 2006, now U.S. Pat. No. 7,761,188 B2, which claims the benefit of U.S. Provisional Application No. 60/668,126, filed Apr. 4, 2005, both of which are hereby incorporated by reference.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic drawing of components of an embodiment of an evacuation system connected to the microcontroller;
DESCRIPTION OF THE PREFERRED EMBODIMENTS Initially, it should be appreciated that like drawing numbers on different drawing view identify identical structural elements. It also should be appreciated that figure proportions and angles are not always to scale. Further, it should be understood that the evacuation system is not limited to the disclosed embodiments. Various modifications and equivalent arrangements may be included within the spirit and scope of the appended claims.
Referring to the drawings, FIG. 1 is a partial schematic drawing of an evacuation system 10 for evacuating suspended particulates from a fluid stream. It should be understood that the fluid stream may be comprised of liquids, gases, and/or solids. Further, the suspended particles may be visible or microscopic particles; organic or inorganic matter. In one embodiment, the suspended particles in a fluid stream are in the form of smoke. Evacuation system 10 includes at least one fluid intake, at least one exhaust outlet and an evacuation motor unit (not shown). As shown, a microcontroller 11 is in functional communication with components of evacuation system 10 such as input signal latches 13, output signal latches 14, an alternate circuit (A/C) synchronization system 15, a motor drive 16 and a remote switch interface 17. Microcontroller 11 is also in functional communication with a display screen 18. In addition, microcontroller 11 is functionally connected to a two-way read/write circuit 20. In the embodiment shown in FIG. 1, read/write circuit 20 includes an antenna 21 which may be present if read/write circuit 20 is a radio frequency identification tag (�RFID�) reader/writer. The read/write circuit 20 may be based on the ISO 15693 standard for communicating with tags at 13.56 MHz. Further, the interface between microcontroller 11 and read/write circuit 20 may include a 3-wire serial interface having a bi-directional clock controlled by microcontroller 11 during command/data write operations and by read/write circuit 20 during data read operations. In one embodiment, evacuation system 10 includes a control panel (not shown). The control panel and display screen 18 may combined into one integral component. In anther embodiment, evacuation system 10 is in functional communication with a filter 22 which includes a second two-way read/write circuit such as RFID tag 23.
Microcontroller 11 contains at least one program configured to control the functionally connected components as well as, when necessary, determining changes in functional or operational parameters of the functionally connected components. As used herein the phrases �functionally connected� shall mean that components, for example, microcontroller 11 and read/write circuit 20, are connected in such a way that signals, data, controls and other applicable modes of information are transmitted therebetween using either suitable direct wired connections or a form of wireless or radio transmission and reception. In one embodiment, in which read/write circuit 20 is an RFID tag reader/writer, an antenna is used to functionally communicate with an RFID tag on another component. Microcontroller 11 may include an external electrically erasable programmable read-only memory (EEPROM) to hold the required programs. An internal EEPROM may be used as it requires fewer I/O pins and makes available more memory. In an alternate embodiment, microcontroller 11 may be in functional communication with a data port, such as a USB connection, to allow changes or replacement of a program.
