Abstract: A speaker box, or enclosure, and kit with five panels connected by flexible couplings is shipped in a stack of four of the five panels, plus two side panels. The flexible couplings may be provided by a single sheet of fabric coupled to the five panels. When the kit is assembled into a speaker box, the five coupled panels circumferentially engage the two side panels, which are shaped as isosceles trapezoids. One side of the assembled speaker box includes two coupled panels, of the five coupled panels, joined with a flat rabbet joint. The assembled speaker box is held together with bundle ties, adhesive, or preferably, both. Openings for a speaker and a connector cup are provided. The kit includes adhesive, instructions, bundle ties with bundle tie locks, a connector cup, and hardware.
Abstract: A method, apparatus and system for communicating in a wireless mesh network may entail receiving a multi-receiver single body broadcast (MRSSB) medium access control (MAC) frame at a mesh node. The MAC frame may include a multiple receiver address field, a previously addressed neighbor field and a message sequence number field, which may be used by the receiving node to know whether it has already received this frame and if not, generate a forwarding frame to forward the data of the received frame but addressed to neighboring nodes except for those which are likely to have previously received the message already. Various embodiments and implementations are also disclosed.
Abstract: A method for establishing communications between a master unit and a plurality of node units. Of the plurality of node units, K node units are assumed to have established communications with a master unit. A first (K+1) node unit of the plurality of node units, desires to establish communications with the master unit. The method includes transmitting from the master unit, a base-station spread spectrum signal having a common signaling chip code, transmitting from the first node unit a second spread spectrum signal with a first identification code using the common-signaling chip code, transmitting from the master unit a third spread spectrum signal with a master unit identification code, using the common-signaling chip code. The method further includes generating at the first node unit using the master unit identification signal, a master unit chip code for transmitting spread spectrum signals to the master unit.
Abstract: A portable cleaning system including a casing for storing a cleaning agent in one compartment and a towel in a second compartment. The compartments may be slidably connected to have an open position and a closed position.
