  • Publication number: 20210052179
    Abstract: The present disclosure provides a method for determining R peaks of an electrocardiogram (ECG/EKG). First, an ECG/EKG complex is provided, and then, a maximum peak of the ECG/EKG complex is obtained. Following that, a half of a largest voltage of the maximum peak is defined as a threshold voltage. Later, an R peak number estimating process is performed to obtain an estimated number of all R peaks of the ECG/EKG complex and a plurality of peaks of the ECG/EKG complex with voltages greater than the threshold voltage and followed by determining whether a number of the peaks is equal to the estimated number of the all R peaks. When the number of the peaks is equal to the estimated number of the all R peaks, the peaks serve as the all R peaks.

  • Patent number: 10504605
    Abstract: A method for testing firmware of an SSD includes: controlling a main memory to emulate volatile and non-volatile memories of the SSD, fetching a testing sequence and a testing criterion, fetching read/write operations from binary codes generated by compiling the firmware, determining whether the read/write operations are associated with a marker, executing the read/write operations when a result of determination is affirmative, otherwise discarding a read/write of data, monitoring whether processes of executing of the read/write operations meet the testing criterion, and generating a result of a test of the firmware when it is monitored that the testing criterion is met.

  • Patent number: 7192156
    Abstract: The present invention is a waterproof indicator light, which solves the problem that the length of the space needed for the battery is too long, caused by the battery needing to be in serial connection for the conventional waterproof indicator light. The invention includes a step-up apparatus in the illuminating module to reduce the number of batteries needed, or to change to a button mercury battery that has a lower voltage and is smaller. Then, the step-up apparatus is used to increase the voltage. By so doing, it largely reduces the space needed for the battery set, increases the length of the refracting surface for the illuminating module, and increases the illuminating effect as well.

  • Patent number: 6776502
    Abstract: A newly constructed fishing lamp is disclosed. It is capable of reducing the production cost and simplifying fabrication process by fabricating several essential parts integrally in one piece so as to save use of extra separated components. Several O-rings are employed to hermetically seal the lamp housing to assure the perfect watertight feature. A durable, colorful, and power saving LED-flash is selected as the light source to emit diffused light-imitating as that of planktons to tempt fish group approaching with the consumption of very small amount of power. A specially designed 360° turnable bearing including a suspension ring to hang the fishing lamp thereby capable of preventing lamps from overturning in the water stream incurring kinking of fishing rope or curling of fishing line that leads to a broken rope or line.
