Abstract: A part of a tube, through which a fluid passes, is cooled by means of an electronic cooling element and a flow rate of the fluid is measured on the basis of a temperature of a surface of the tube cooled. Not only can the flow rate of the liquid flowing through the tube be determined in a noncontacting manner and a very small flow rate of the liquid be determined, but also the tube is cooled so that no bubbles are generated, and thus the measurement of the liquid, which is apt to generate gases, such as low boiling point liquid, is possible. In addition, the measurement is not influenced by the gases dissolved in the liquid and merely the temperature difference resulting from the flow of the fluid, that is, the rise of the temperature of the fluid, is detected to prevent the measurement from being influenced by the installing posture of the flow meter, so that a highly accurate measurement is possible. Consequently, stable and sure controlling flow rate of liquid is possible.

Abstract: Disclosed is an apparatus and method for determining a read level voltage to apply to a block of memory cells in a non-volatile memory circuit. A prediction value is compared to a prediction indicator to determine whether a new read level voltage to be applied to read the memory cells should be estimated. If a new read level should be estimated the new read level is calculated as a function of an initial read level and a dwell time and a number of program/erase cycles. A controller provides one or more programming commands representative of the new read level voltage to the memory circuit to read the cells.

Abstract: The disclosed subject matter includes a memory system with a flash memory and a flash memory controller. The flash memory controller is configured to divide the flash memory into virtual segments, each segment including blocks of flash memory cells. The controller is also configured to receive a write request to a location designated by a memory identifier and to map the memory identifier to a segment. When the segment matches an open segment and an open block can store the data, the controller is configured to retrieve the open segment and the open block from a collection tracking open blocks and to write the data to the open block. When the segment is different from the open segment, the controller is configured to close the open block, to write the data to a block in the segment, and to update the collection with the block in the segment.
