An LED module includes a latching component, a frame holding an LED thereon, a heat spreader located in the latching component and a heat transfer member having a heat-dissipating unit remote from the LED and a heat pipe thermally connecting with the heat spreader, the LED and the heat-dissipating unit. In the systems and method, burst electrical or mechanical stimulation to one or more swallow-related nerves andor muscles can be timed for delivery between the expiratory phase of the respiration cycle, following detection of an apneic event in the subject. One of the frequency-divided clocks is selected, according to the transfer rate detection results, and used as the operating clock for an interface unit 110, the process controller 130, a buffer unit 140, and a transfer controller 150. The network further includes at least one time server, which generates a global time clock to which local time clocks of all storage peers of the pseudo peer-to-peer network are synchronized such that a global address table updated by the configuration server is activated by all storage peers at the same scheduled time to be consistent throughout the pseudo peer-to-peer network at all times. The magnetic parts comprise an epoxy resin in which iron-based amorphous particles FINEMET\xae serving as magnetic particles are dispersed, and the magnetic parts are integrated with the planar coils by being bonded to the planar coils in an electrically insulated state by means of the epoxy resin. The locking plate is mounted for pivoting and sliding movement, and is provided with a holding claw for engagement within a second recess at the distal end thereof.
