The invention comprises methods of settling wagers in a game with a PlayerDealer pool which entail reserving some of the funds in the PlayerDealer pool to pay bonuses and additional wagers and in some cases retiring more funds from the PlayerDealer pool than the amount won or lost. The bed sheet may act as a barrier between a sleeping person and the mattress, existing bedding, or both to deter vectors, pests, or both from passing from the mattress or bedding to a sleeping person. The misalignment estimate may include an inversion of at least one measurement from an alignment sensor. The outputs of the NCDL are observed by an observability circuit that captures the outputs of the NCDL.
