Abstract: An apparatus for controlling a pressure on at least one tire of a vehicle based on a remaining time of travelling to a destination of the vehicle and/or an expected load of the vehicle on a subsequent trip, includes: a data acquisition module to acquire data, the data being indicative of the remaining time of travelling to the destination and/or the expected load of the vehicle on the subsequent trip. The apparatus further includes a data processing module to determine a time of changing the pressure on the at least one tire based on the acquired data and a control module to issue a control signal to initiate the change of the pressure at the determined time.

Abstract: A pressure regulating device is provided for at least one tire of a commercial vehicle, having a relay valve which performs compressed air loading of a working line which leads to the tire starting from a pressure source in accordance with a pneumatic pilot controller which has an electropneumatic converter for converting an electric actuating signal into a corresponding pneumatic pilot control signal for the relay valve. The converter has an electropneumatic aeration valve and an electropneumatic ventilating valve for pneumatic signal specifying for increasing or reducing the tire pressure. The pneumatic signal specifying takes place according to special regulations.

Abstract: A tire pressure controlling device for a tire of a vehicle wheel filled with compressed air, includes a control valve unit for filling the tire with compressed air and/or venting compressed air therefrom. The control valve unit is supplied from a compressor for generating the tire filling pressure. The compressor for compressing air drawn in from the atmosphere is driven by the mechanical rotary movement of the vehicle wheel, as a transmission disposed therebetween transmits the rotary driving movement of the vehicle wheel to the drive shaft of the compressor unit.

Abstract: In conventional memory arrays in which a bit line is shared by memory cells, a cell current flows over into neighbor cell(s) in a program verify process, and therefore, the threshold of a memory cell to be programmed is erroneously determined to be lower. Therefore, in a program verify process, a control circuit 3 writes a fail value to a neighbor cell buffer 5 when all neighbor cell(s) having an offset of n or less from a memory cell to be programmed are in the erased state, and when otherwise, writes a pass value to the neighbor cell buffer 5. The control circuit 3 verifies input write data and also verifies data stored in the neighbor cell buffer(s). In the latter verify process, a verify voltage higher than an ordinary one is used to compensate for the leakage of cell current.

Abstract: Self-test instructions are loaded from a tester into a configuration array of a memory device, and then a control circuit of the memory device sequentially reads and executes the self-test instructions while the tester is in an idle state. Data patterns are written to a main memory array of the memory device the internal self-test process. The control circuit includes a comparator for detecting defective memory cells by comparing data values read from the main array with the data pattern previously written into the main memory array. A BIN counter identifies the currently-executed self-test instruction, and is read and transmitted to the tester when an error is detected.
