Granted: 2005-05-10
Abstract: The invention provides a mechanism for adjusting the opening between adjacent sieve slats of a combine sieve. A wrist connector is connected to a conventional slat connection member. An electrically activated linear adjuster which includes a linearly moveable shaft is connected to the wrist connector to move the slat connection member fore and aft. The actuator is electrically controlled by way of an adjusting switch. The actuator provides an electrical signal output responsive to the linear position of the shaft, which signal output is directed to a meter which provides a visual indication of the opening between adjacent slats. The combine operator can therefore monitor and control the opening between adjacent slats of the sieve from a remote location, specifically the cab of the combine.

Abstract: Synchronizing a local timing unit to a central timing unit in a first switching system to determine the difference in timing between a connected external link and the local timing unit. This timing difference is then transmitted to the central timing unit which utilizes this information to adjust a frequency synthesizer that outputs the frequency of the external link to a second switching system. The local timing units are synchronized to the central timing unit via multiple timing paths set up through switching units within a switching network of the first switching system. The timing difference transmitted from the local timing unit is transmitted over a plurality of control paths through the switching units. Each switching unit switches one bit of data for each group of data being received on each of the external links connected to the first switching system. Any of the external links connected to the first switching system can be utilized to provide timing information for the second switching system.

Abstract: The procedure for regulating the concentration of sodium in a dialysis fluid at a predetermined level so that the fluid inside the patient tends towards a desired concentration as the patient's blood and dialysis fluid are circulated on either side of a semi-permeable membrane (4) in a dialyser (1) consists of determining the concentration of sodium in the dialysis fluid, the desired concentration, the perfusion flow rate and the concentration in the perfusion fluid and adjusting the dialysis fluid concentration accordingly. The concentration of sodium in the dialysis fluid is determined from a set formula based on the desired concentration, the concentration in the perfusion fluid, the fluid flow rate and the dialyser separating capacity. The separating capacity is determined by circulating at least two dialysis fluids with different conductivities, taking two or more conductivity measurements before and after the dialyser, and calculating the separation capacity from the values obtained, using a second formula.

Granted: 2003-03-25
Abstract: A method, apparatus and article of manufacture for compensating for carrier frequency error is disclosed. An FM signal is received from an antenna and the received FM signal is provided to a receiver. The receiver takes the FM signal at the carrier frequency and outputs a baseband signal. This baseband signal is then processed by a DSP  which provides carrier frequency compensation and decoding to produce a data stream that a microprocessor provides to a host device.  Frequency differences between the FM carrier frequency and the frequency used to demodulate the FM signal can shift the DC bias level of the baseband signal. The DSP compensates for such frequency difference by using a receive compensation value and applying it to each received signal sample. When transmitting, data to be transmitted is provided from the host device to the DSP via a microprocessor. The DSP  provides encoding and carrier frequency compensation of the data to provide a baseband signal to a transmitter that modulates the baseband signal to produce anFM signal at a desired carrier frequency. Frequency differences between the desired FM carrier frequency and the frequency used to modulate the baseband signal can produce errors in receiver systems. The DSP compensates for such a frequency difference by using a transmit compensation value and applying it to each encoded signal sample.

Title: Adaptive re-ordering of data packet filter rules
Inventor: KRISHNAN P
IPC: G06F13/00
Filed: 1999-10-28
Granted: 2003-09-30
Abstract: A packet data filter which stores ordered rules and sequentially applies the rules to received data packets to determine the disposition of the data packet. The packet filter maintains a match count in memory which indicates the number of times each rule matched an incoming data packet. Periodically, at the initiation of a user, or based on operating parameters of the filter, the rules are automatically re-ordered based on the match count. As a result of the re-ordering, rules with higher match counts are moved earlier in the sequential evaluation order and rules with lower match counts are moved later in the sequential evaluation order. As such, rules which are more likely to match incoming data packets are evaluated earlier, thus avoiding the evaluation of later rules. In order to prevent a re-ordering which would change the overall security policy of the packet filter, pairs of rules are compared to determine if they conflict (i.e., the swapping of the two rules would result in a change in the overall security policy).  During reordering, the swapping of conflicting rules is prevented.
