    摘要: A programmable logic device (PLD) data transfer cable includes a parallel interface, a programming interface, and a logic control circuit. The parallel interface is used for connecting to PLDs. The logic control circuit includes a first group of transmission channels, a second group of transmission channels, a first group of switches, and a second group of switches. The first and second group of switches control the working status of the first and second group of transmission channels respectively. The electrical connections between pins of the parallel interface and the programming interface when first group of transmission channels are activated are different with those when second group of transmission channels are activated.

    摘要: Error correction coding across multiple channels is provided in multi-channel transmission systems. Specifically, redundancy is provided by selecting a portion of original data from each of a plurality of original channels, performing at least one encoding operation using the portions of original data to produce at least one portion of redundancy data, including the portion of redundancy data in at least one redundancy channel, and transmitting the redundancy channel along with the original channels. Error correction is achieved by receiving at least one redundancy channel and a plurality of original channels, selecting a portion of redundancy data from the redundancy channel, selecting a portion of original data from each of the original channels, and performing at least one decoding operation using the portion of redundancy data and the portions of original data to correct at least one error in the portions of original data.

    摘要: A method for testing using an automated test equipment (ATE) is disclosed. The method comprises capturing a radio frequency (RF) signal using a digital port on automated test equipment, wherein the RF signal is transmitted from a device under test (DUT) to be tested by the automated test equipment. It also comprises sampling the RF signal at a high sampling rate using a digital channel associated with the digital port. Further, it comprises generating a discrete signal using results from the sampling. Finally, it comprises determining a frequency and amplitude of the RF signal using the discrete signal.

    摘要: A switch-mode power supply for selectively providing power from a main power source and a standby power source to an electronic device is provided. The switch-mode power supply includes a signal input, a first transistor, a second transistor, a driving circuit, and a switching circuit. The signal input is used for receiving a control signal. The driving circuit and switching circuit connect the signal input to the gate of the second transistor in series. When the driving circuit detects the first transistor is switched off, the gate of the second transistor is immediately pulled up to open the second transistor, and when the driving circuit detects the first transistor is switched on, the gate of the second transistor is immediately pulled down to close the second transistor.

    摘要: A linear motor and/or compressor (10; 100; 300; 500; 600) comprises a housing (20; 120; 311; 511) fitted with a number of electromagnets (40, 40′; 140, 140′; 315, 315′, 316; 515a-515c, 635a-635d), a shuttle (50; 150; 350; 550; 650) with a central guide (30, 30′; 130; 356, 356′; 520; 655) for keeping it coaxial with the electromagnets and a suspension mechanism for the shuttle including mechanical spring, gas spring and magnetic spring arrangements. The electromagnets form a number of axially exposed magnetic gaps to interact with axially exposed magnetic gaps formed on the shuttle to cause it reciprocate by push-and-pull forces. A phase difference can be produced between the electromagnets to improve shuttle suspension. The central guide can be made hollow to circulate a coolant to cool the compressor from inside. A multi-stage compression arrangement is formed between the shuttle and the electromagnets so that the compressor can work in a double-acting manner to compress the process fluid progressively for a high pressure output. A further suspension (640,640′) can be sued for the stator (630) so as to ensure the machine's vibration-free operation.
