Abstract: A post regulation control circuit aims to monitor ancillary output power generated from a power supply. The power supply includes at least one primary output circuit to provide a primary output power. A post regulation circuit obtains the primary output power and regulate to an ancillary output power. The monitor circuit sets an abnormal level and obtains a detection power from the post regulation circuit to compare with the abnormal level. Determining whether to output a driving pulse wave according to the detection power is over the abnormal level or not, or stop outputting the driving pulse wave.

Abstract: Disclosed is a sales system for lots of items that includes business rule definition logic. The sales system also includes offering creation logic that is operative to dynamically create different offerings for items in the lots. The offering creation logic optimizes return based on one or more of the business rules by using different offering parameter values for the different offerings.

Abstract: A switching power supply apparatus including an AC-to-DC conversion circuit, a hysteretic relay and a relay control circuit is provided. The AC-to-DC conversion circuit includes a current limit resistor, and the current limit resistor is configured to suppress an inrush current generated during the AC-to-DC conversion circuit converts an AC input voltage into a DC output voltage. The hysteretic relay is coupled with the current limit resistor in parallel. The relay control circuit is coupled to the AC-to-DC conversion circuit and the hysteretic relay, and configured to control the hysteretic relay to turn on in response to one of an over drive pulse signal and a holding modulation signal when the DC output voltage reaches to a predetermined value, so as to bypass the current limit resistor, wherein an enabling time of the over drive pulse signal is different from that of the holding modulation signal.

Abstract: A bicycle generator mounting structure comprises: a base, an adjusting member, a connecting member, and a flexible member. The adjusting member is disposed on and adjustable in position with respect to the base mounted on a bicycle frame. The connecting member is disposed on the adjusting member. The generator is connected to the connecting member via the flexible member which is capable of returning to its original shape after deformation, hence, the flexible member can absorb the noise caused when the bicycle is running and keep the generator in optimal contact with the wheel.

Abstract: A method of producing riboflavin by culturing riboflavin-producing microbes in a culture medium using a plant oil or an animal oil as a carbon source, forming and accumulating riboflavin therein and collecting riboflavin therefrom, wherein a carrier of a clay mineral having oil-adsorbing property, a chemically treated product thereof or a calcium compound is made present in the culture medium. The riboflavin is produced maintaining a high yield and at an increased production rate at a low cost without requiring cumbersome operations for concentrating and recovering the riboflavin. It is further allowed to recover the riboflavin by effectively utilizing the waste plant oil or the waste animal oil that is to be disposed of.
