Abstract: Methods and apparatus for implementing standing wave oscillators (SWOS) using coplanar striplines (CPS). One example is given by a quarter-wavelength (?/4) coplanar stripline standing wave oscillator (SWO), while another implementation utilizes a closed-loop coplanar stripline configuration. In various aspects, SWOs are configured to optimize sinusoidal performance at high frequencies with low power dissipation by incorporating various features that dramatically increase the quality factor Q of the oscillator. In particular, in one aspect, an amplitude-dependent tailored distributed amplification scheme is employed as a mode control technique using multiple amplifiers having different gains along the length of the coplanar stripline. In another aspect, a coplanar stripline configured such that its resistance per unit length R and conductance per unit length G are discreet or continuous functions of position along the coplanar stripline is employed to reduce SWO losses.

Abstract: A safety circuit for a rechargeable cell is employed as a simple, low cost, fuel gauging circuit. The safety circuit includes an undervoltage circuit having a reference voltage. The input of the safety circuit is selectively coupled between the voltage of a rechargeable cell and a scaled down voltage of the rechargeable cell. The scaled down voltage corresponds to a predetermined capacity threshold. A user or electronic device actuates a switch that couples the scaled down voltage to the safety circuit. The safety circuit compares this scaled down voltage to the reference voltage of it's under voltage circuit. If the scaled down voltage is above the reference voltage, the safety circuit causes a transistor coupled serially with the cell to be on, or in a conductive state, so as to allow current to flow through a capacity indicator like a LED. If the scaled down voltage is below the reference voltage the safety circuit causes the transistor to enter a high impedance state, thereby turning the indicator off.

Abstract: A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.

Abstract: A method to manage nodes in a ZigBee network. In a ZigBee network including a plurality of nodes, a multicast group is generated including at least two nodes among the plurality of the nodes. A multicast group coordinator (GC) which manages the multicast group is set among the nodes forming the multicast group. The multicast group includes the GC, a multicast group member (GM) requesting to join the multicast group, and/or a multicast router (MR) which links GMs to each other or links the GC and the GC. Accordingly, since the GC manages the multicast group, the load is decreased and the packet data transmission rate is enhanced.
