    Abstract: In a time division multiplex access asynchronous transfer mode wireless network wherein network interface units (NIUs) are connected to a base transceiver station (BTS) by way of a radio frequency (RF) wireless link comprising time slots which are grouped into frames, there is presently no method or apparatus to allow dynamic bandwidth allocation while maintaining a minimum bandwidth allocation to NIUs. Using a combined Guaranteed Bandwidth Allocation (GBA) scheme with a Dynamic Bandwidth Allocation (DBA) scheme, a configurable number of time slots can be permanently assigned to an NIU using GBA while the NIU can request additional timeslots using DBA. Using a queue occupancy threshold and a queuing delay threshold, the DBA scheme takes into account the GBA time slots which have been allocated, so that time slots are not unnecessarily requested by an NIU. At the BTS level, a time slot manager utilizes a frame look ahead procedure to allocate time slots based on the queue occupancy forwarded from the NIU. Additionally, a configurable parameter is defined which reflects the level of traffic in an NIU, to allow pro rated allocation of time slots.

    Abstract: A combined transmission unit for TMDS signals and LVDS signals. A first (LVDS) transmission unit includes a set of first input terminals to receive first data, and a second (TMDS) transmission unit includes a set of second input terminals to receive second data. A phase locked loop (PLL) generates a first set of output clock signals to the first transmission unit in a first mode and a second set of output clock signals to the second transmission unit in a second mode according to a mode selection signal. The first and second transmission units are able to transmit the first data to the first and second external input units in the first and second modes respectively, according to the mode selection signal and the first and second sets of output clock signals.

    Abstract: A method of determining a clearance between a magnetic transducer and a magnetic recording medium during a track seeking operation, the magnetic recording medium being moveable with respect to the transducer and including at least a test track and a reference track, which method comprises the steps of: at least partially erasing a predetermined area of the recording medium including at least one test track and one reference track; writing a first series of predetermined magnetic transitions along a spiral trace, formed by seeking operation of the transducer, on the at least one test track in the predetermined area; reading the test track and obtaining a pulse width of signals read back from the test track (test track pulse width) at a predetermined amplitude level; writing a further series of predetermined magnetic transitions identical to the first series on a reference track of the recording medium in the predetermined area; reading the reference track and obtaining, a pulse width of signals read back from the reference track (reference track pulse width) at the predetermined amplitude level; and calculating the difference between the test track pulse width and the reference track pulse width, said difference being indicative of the clearance between the magnetic transducer and the magnetic recording medium during track seeking.
