Title: System controlling air fuel ratio of lean burn engine with NOx storage catalyst
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1999-03-22
Abstract: An (inferential) catalyst (37) temperature measurement unit (31) is combined with an engine air fuel ratio control unit (31) to vary degree of combustion in lean and rich running, as a function of the measured temperature. PREFERRED FEATURES:- The ratio controller varies rich mixture (TR) combustion interval as a function of the measured catalyst temperature (TCAT) in a state in which a ratio between lean mixture (TL) combustion time (an interval) and rich mixture (TR) combustion time is constant. The higher the catalyst temperature, the more the air fuel ratio control unit raises the rich mixture combustion interval (TR) at each opportunity. Further algorithms are described. The unit assesses NOx catalyst temperature indirectly, from other variables. Further components include a heater (47) for the gas concentration sensor and a controller (31) raising the heater to predetermined temperature. Operation of the catalyst temperature measurement unit, is based on a control magnitude for the heating unit. Catalyst temperature measurement is based on the electrical heating energy required to activate the gas concentration sensor.

Title: I/O buffer for transmission bus of high frequency and low oscillation voltage e.g. GTL-plus bus uses active pull-up components for improving ring-back effect
Inventor: HUANG JINCHENG
IPC: H03K19/003
Filed: 1999-10-19
Abstract: The buffer controls the resistance of variable resistor for pulling up the bus. When the input voltage is high, it can connect the variable resistor and reduce the resistance as hundreds of ohms; when the input voltage is low, it can increase the resistance to infinite and cut the connection. Therefore, the invention can not only effectively reduce the influence from ring back effect, but also greatly reduce the power consumption and avoid the cost of extra resistors on the circuit board.

Filed: 1999-11-26
Abstract: Control systems, such as building management and process control systems suffer from the problem of matching or adapting the semantics for the data exchange of the system being used, in order to avoid errors. The method proposed aims at guaranteeing a correct data exchange of data between the devices, or components, of the respective systems. Data from a first component (server) (10) is communicated to the second component (building manager) (11) and compared with entries in the semantics list or table (18). Depending on the result of the comparison, corresponding data is outputted for the second component (building manager).
