A sewer backup alarm and overflow prevention device eliminates raw sewage spills by preventing pressure buildup in sewer drains. One or more sewage level sensors may be coupled to an alarm and/or to an automatic water main shut-off valve. The level sensor may detect excess fluid levels in a sewer lateral line. The sewer backup alarm and overflow prevention device may include a joggle which is a component of a non-mechanical backflow prevention device. The level sensor may detect fluid levels in the lower portion of the joggle and activate the automatic water main shut-off valve and/or the alarm. The sewer backup alarm and overflow prevention device may include at least one two-way, in-line cleanout tube which may extend vertically upwardly from the joggle. The level sensor may be mounted in the vertical cleanout tube. The components may be contained within a seamless polyethylene vault for ease of installation and protection against root intrusion.

Persuasive environmental recovery system

Disclosed is apparatus for scanning a field of view for two-dimensional data and for rapidly processing the data. There is a video device viewing the field of view and producing a two-dimensional matrix of pixel data as an output representing a plurality of pixel positions of the field of view. A digital memory receives and holds the two-dimensional matrix of pixel data output from the video device in a plurality of multiple pixel data words. There is also a digital processor including a register for receiving pixel data and logic for processing data to decode it. Primarily, there is pixelizer logic and associated circuitry connected between the digital memory and the digital processor for removing data associated with a specified pixel position within the field of view from an associated one of the plurality of multiple pixel data words in the digital memory and for placing the data into a pre-established bit position within the register of the digital processor. The time required to repeatedly obtain the necessary pixels for processing is thereby greatly reduced and minimized.

Apparatus is disclosed for automatically determining the volume of an object. The volume system includes a height sensor and a width sensor positioned in generally orthogonal relationship and each constructed to reflect light from a corresponding surface of the object. The height sensor and the width sensor each include a plurality of charge coupled devices for sensing light reflected from the object. The output from the height sensor and the width sensor are provided to a data processor for evaluating the data to determine a plurality of incremental volume of the object as the object is displayed in relation to the height and width sensors. The plurality of incremental volume are then added to determine the volume of the object.

A method and apparatus for locating multiple bar codes in a field. The apparatus includes a microcomputer programmed to detect the existence of bar codes in location cells in the field and then apply a location score to each location cell. Based on the scores assigned to the location cells, a particular location cell is selected and the location cells surrounding the selected cell are analyzed to determine whether they might contain a bar code segment. A location cell that is determined to be sufficiently likely to contain a bar code segment will be appended to the first selected location cell. In this manner, a bar code in the field can be located. The determination of whether the located bar code is a primary or a secondary bar code is made by further analyzing the located bar code. The further analyses may be to determine the located bar code's length, whether it has a predetermined prefix, or whether it has a predetermined pattern of descenders from its constituent line segments. A preferred embodiment of the inventive method and apparatus analyzes the image recorded in the field to locate areas containing Postnet bar codes. The number of bars in each Postnet bar code found in the field is then counted and a determinatinon is made as to whether the number of bars in the Postnet bar code equal a valid number of bars. If the field contains only a bar code containing a valid number of bars, that Postnet bar code is decoded to provide a valid ZIP code. If, however, a Postnet bar code is found in the field that does not contain a valid number of bars, the Postnet bar code is flagged as a forwarding Postnet bar code. The Postnet portion of the Postnet bar code is then decoded to provide a valid forwarding ZIP code.

A sanitary door handle for the inside of a public toilet door which includes a generally circular handle element having means for rotating the handle to a new position with the handle being moved through a sterilizing bath as it rotates. Means are provided for effecting rotation of the handle on each opening of the door.
