Title: Formula processor
Inventor: REED DAVID
IPC: G06F12/08
Filed: 1992-07-28
Granted: 2001-03-20
Abstract: A formula processor which computes results for a group of formulas in which at least one formula uses the result of another formula. The formula processor receives the formulas from a host and returns computed results for the formulas to the host for storage in a main memory. Formulas are received as a sequence of tokens, each token describing operands or operations.      The formula processor is pipelined; as one token is interpreted and processed by the formula processor, subsequent tokens are received. The formula processor uses a computation element which is capable of performing only certain operations; before attempting each operation described by a token, the computation element determines whether the operation can be performed by the computation element - if it can be performed, it is; otherwise, the host may perform the operation itself, or rewrite the operation so the formula processor can perform it. After the formula processor computes a result for a formula, it stores this result in a cache memory. Thereafter, the formula processor can retrieve the result stored in the cache memory and use the retrieved result to compute a subsequent formula. The operands to a formula may be values or pointers indicating how to locate values; the formula processor converts pointers into values when required for a computation by requesting resolution from the host microprocessor, or, alternatively, by retrieval from the cache.

Title: Update marker system for navigation of an automatic guided vehicle
Inventor: BLOOMFIELD BRYAN ALEXANDER
IPC: G05D1/02
Filed: 1991-10-07
Granted: 1998-10-20
Abstract: An improved accuracy position and direction updating system for use with an auto matic guided vehicle that navigates by dead reckoning. Permanent magnets providing detectable position indicators are mounted in the floor and may be at widely spaced locations such as fifty feet apart along the route of the vehicle. A row of Hall sensors is transversely mounted on the vehicle. The sensors detect the lateral location of each floor magnet relative t o the vehicle as the vehicle passes over the magnet. Sensors are precalibrated, correcting for errors in sensor null voltage readings due to changes in sensor characteristics due to causes comprising aging and temperature. Data from five sensors that are closest to the magnet are correlated with a stored pattern of magnetic field and their position data are averaged to determine a first estimat e of the lateral or first dimensional position of the vehicle, A running average is calculated from sequentially acquired estimates to improve the results. Such precalibration and averaging provides an improved accuracy of the lateral or first dimensional posi tion measurement between the array of Hall sensors and the magnet. A high frequency measurement of the time at which the signals fr om the row of sensors reaches a peak value, which is the time that the row of sensors arrives at the magnet, provides an imp roved second dimensional position measurement. More than one magnet is read concurrently to provide position and bearing inform ation during one processing cycle.

Abstract: Within a document printing system, a dot generator for determining dot ON/OFF states for a multiple channel matrix print head includes a RAM memory in which is stored print characters received from the print system. The received print characters are stored in ASCII format in predetermined character box memory locations within the RAM memory. The dot generator further includes a ROM memory having (1) a first storage area containing an association table correlating each one of the dot print addresses or locations within the document print zone with one of the character box memory locations within the RAM memory; (2) a second storage area containing an association table correlating each one of the dot print locations with a character box print location row and column number; and (3) a third storage area containing dot state ON/OFF values corresponding to each row of each standard ASCII character. A ROM lookup procedure is utilized to determine the ON/OFF state for each dot location within the print zone. In brief, the dot generator performs the followings steps: (1) The dot generator receives a dot address from the print system and utilizes this address to fetch the character box memory locations (BOX#) for that dot from the first storage area within the ROM. (2) The dot generator fetches the ASCII character from RAM for the BOX# provided by step 1. (3) Simultaneously with step 2, the dot generator fetches the ELEMENT#, a number describing a dot's relative position within a character box, from the second storage area within the ROM, (4) The dot generator then extracts the dot's printing state,i.e. ON or OFF, from the third storage are within the ROM using the ASCII character provided by step 2 and the ELEMENT# from step 3. (5) This process repeats until all channels in the printhead have been determined.

Abstract: A runoff and waste-water interceptor includes a central treatment chamber, a separate inlet basin, and a separate outlet basin. An inlet allows liquid into the inlet basin, and an outlet allows liquid to flow out of the outlet basin. A first conduit communicates with the inlet basin at a level below the inlet and has a second end communicating with the treatment chamber. A second conduit has a first end communicating with the exit chamber at a level below that of the outlet, and a second end communicating with the treatment chamber. The second ends of the two conduits are located at opposed positions within the treatment chamber to avoid short-circuiting of the flow. A by-pass conduit communicates between the two catch basins and is located above the first ends of the respective conduits. Under low flow conditions, all liquid entering the inlet basin flows through the first conduit and into the treatment chamber, while any liquid leaving the treatment chamber flows through the secondconduit and outlet basin, thence out through the outlet. Under high flow conditions, when liquid enters the inlet basin faster than it can exit through the first conduit, the excess liquid accumulates until it rises to the by-pass conduit, whereupon it travels along the by-pass conduit to the outlet basin, from where it exits through the outlet.
