Abstract: The subject of the invention is a universal bed insert, built by air mattress, combined with airtight valves and method for producing thereof. The insert, produced with the application of said method makes it possible, that the sponge, the airtight covering of the sponge, and the air within the insert result in a higher level of convenience when using the insert. The insert according to the invention is built by an air mattress filled with sponge of open cell structure, as well as valves built into the air mattress. The characteristic of the insert is, that in the air mattress (2) sponge (3) of open cell structure, low body-density and low compressive stress is used, where the value of the body-density is preferably 10-23 kg/m3 and the value of compressive stress is preferably 1.0-2.5 kPa. the material of the sponge (3) used is polyurethane, or silicone or rubber foam.

Abstract: A method and apparatus for medium access control in a receiver is shown, involving frequency hopping through each of a plurality of channel frequencies for the receiver, monitoring a baseband section of the receiver using a data quality detector (DQD) circuit configured to assert a DQD signal when valid data is sensed at the output of a demodulator of the receiver, waiting a first preset period of time after changing the channel frequency for each frequency hop and monitoring whether the DQD signal is asserted, resuming frequency hopping if the DQD signal is not asserted within the first preset period of time, and maintaining a current channel frequency in order to receive a data packet if the DQD is asserted.
