Abstract: A wireless synchronous time system comprising a primary master event device and secondary slave devices. The primary event device receives a global positioning systems “GPS” time signal, processes the GPS time signal, receives a programmed instruction, and broadcasts or transmits the processed time signal and the programmed instruction to the secondary slave devices. The secondary slave devices receive the processed time signal and the programmed instruction, select an identified programmed instruction, display the time, and execute an event associated with the programmed instruction. The primary event device and the secondary devices further include a power interrupt module for retaining the time and the programmed instruction in case of a power loss.

Abstract: A battery pack includes a case and an adapter contoured to mate with a battery socket of a power-consuming device. The battery socket is formed to receive an intended, standard-sized battery. The battery pack includes positive and negative leads electrically connecting the adapter to the case and two battery slots formed to receive intended, standard-sized batteries in parallel electrical communication with the positive and the negative leads.
