    Abstract: An automatic clamping analog-to-digital converter (A/D converter) is provided, which includes an A/D converter, a switch, a comparator, a bidirectional counter, and a digital-to-analog converter (D/A converter). Wherein, the A/D converter receives an analog signal from a node, and then converts the analog signal into a digital signal according to a DC offset level. The switch is coupled between the node and a fixed voltage level, and is turned on or off according to a clamping signal. The comparator outputs a compare signal according to a comparison result between the digital signal and an offset value. The bidirectional counter outputs a count, and increases or decreases the count according to the compare signal. The D/A converter converts the count into the DC offset level and provides the DC offset level to the A/D converter.

    Abstract: An fMRI scan is performed using a multi-element head coil and multi-channel receiver to acquire time course image data. One imaging gradient is eliminated from the pulse sequence used to acquire the time course image data enabling images to be acquired at a very high frame rate. The multi-channel NMR data is combined and reconstructed into a series of image frames using an imaging inversion operator.

    Abstract: A Quality-of-Service-enabled access point (QAP) broadcasts an initial number of time slots and an upper limit to a Quality-of-Service-enabled station (QSTA). The QSTA generates a random number between 0 and 1. The QSTA selects a time slot from the initial number of time slots for data transmission contention and issues a TXOP reservation request to the QAP in the time slot if the random number is lower than the upper limit. The QAP generates a reservation result. The QAP broadcasts the reservation result to the QSTA if more than one QSTA issued reservation requests in the same time slot. The QSTA selects a new time slot for data transmission contention and issues a new TXOP reservation request to the QAP in the new time slot if the previous reservation is not successful according to the reservation result.
