  • Patent number: 11112981
    Abstract: The invention introduces a method for configuring impedance of memory interfaces, performed by a processing unit, including: setting a first impedance value associated with an on-die termination (ODT) for a receiver of a controller to a first default value; setting a second impedance value associated with a driver variable resistance for a transmitter of a memory device to a second default value; performing tests for test combinations each comprises a third impedance value associated with a driver variable resistance for a transmitter of the controller and a fourth impedance value associated with an ODT for a receiver of the memory device; and storing a test result for each in a predefined location of a static random access memory (SRAM), thereby enabling a calibration host to obtain the test result for each from the SRAM.

  • Publication number: 20120115059
    Abstract: An electricity output managing system for a fuel cell stack is disclosed. It includes a fuel cell stack, many power switches, an electricity adjusting module, multiple thermal sensors, and a controller. This electricity adjusting module is provided to combine the electricity outputs from these power switches into a single final output. The thermal sensors can detect the inner temperature values of the fuel cell units. The controller can receive the inner temperature values via these thermal sensors and calculate an average of all the inner temperature values which is a floating one. When one of the inner temperature values falls outside a normal range or one of the inner temperature value's variation rates exceeding a preset reference value, the controller turns off the power switch of the corresponding fuel cell unit and sends out a warning signal. So, it can effectuate the fuel cell management by monitoring the inner temperatures of these fuel cell units.

  • Patent number: 7105072
    Abstract: A method for processing a film. The method impressing the whole surface or a selected surface of the film to form protuberant structures on the film by using a transfer and an impresser which has grain projections formed thereon, wherein the protuberant structures have a protuberant shape with an opening hole on the tip or without an opening hole on the tip.

  • Patent number: 5853138
    Abstract: A plastic film processing apparatus adapted for processing tiny pores in a plastic film, enabling it to be torn in any direction, the apparatus including two lifting blocks vertically adjusted by a respective adjusting screw, an impression cylinder revolvably mounted between the lifting blocks by bearings, a film transfer cylinder having fine grains raised from the periphery and peripherally disposed in contact with the impression cylinder for processing tiny pores in the plastic film passing through.

  • Patent number: 5244906
    Abstract: Insects, especially sucking insects, such as brown planthoppers, and phytophageous mites, such as two-spotted spider mites, are controlled by applying an oxadiazole or thiadiazole compound substituted on a carbon atom by an aliphatic nitrogen heterocyclic moiety composed of at least one five or six membered ring. The compound 3-(3-amino-1,2,4-oxadiazol-5-yl)-1-azabicyclo[2,2,2]octane is typical.
