Abstract: A method and apparatus for measuring the rate of flow of an ion-containing fluid in a channel are disclosed herein. The apparatus includes a captive sensor operable to detect changes in capacitance value due to the deflection of the ions in the fluid by a magnetic field, and a processor operable to determine a flow speed of fluid from the detected change in capacitance value and a predetermined value of magnetic field strength. Such apparatus may be implemented using CMOS technology. The apparatus may operate in a magnetic field generated by a permanent magnet and measure the flow reliably.

Abstract: A time manager controls one or more timing functions on a circuit. The time manager includes a data storage and a time calculator. The data storage device stores a first indication of a performance characteristic of a memory cell at a first time. The data storage device also stores a second indication of the performance characteristic of the memory cell at a second time. The time calculator is coupled to the data storage device. The time calculator calculates a time duration between the first time and the second time based on a change in the performance characteristic of the memory cell from the first indication to the second indication.

Abstract: Aspects of the present disclosure relate to phase-change materials. In accordance with an example embodiment, a phase-change material has a crystalline structure that manifests changes that increase as a function of time. For example, such changes may be implemented for monitoring the time that a perishable item has been exposed to an environment having a temperature that is greater than a threshold temperature. Based on the changes, a characterization is provided, indicative of the exposure of the phase-change material to the environment having the temperature that is greater than the threshold temperature.

Abstract: Flow sensors for measuring the flow of an ion-containing fluid may be implemented using mechanical or electrical techniques. Mechanical flow sensors are have moving parts and therefore may be unreliable after some time and are expensive to manufacture. Hall-effect type flow sensors typically require a reversible magnetic field to compensate for electrochemical effects. A flow meter including such a sensor uses an electromagnet. A flow sensor (100) is described using a capacitive sensor (10) and processor (12) to determine the flow rate from a change in capacitance and a magnetic field. Such a flow sensor may be implemented using CMOS technology. The flow sensor may operate in a magnetic field generated by a permanent magnet and measure the flow reliably.
