Abstract: Described herein is a modular outlet system that provides flexibility in locating switches, outlets, and sensors. A base can be recessed into a surface, such as a wall, floor, or ceiling and can be connected to a power source. The base can accept multiple types of inserts. The inserts can include switches, outlets, sensors, and blank plates. The inserts can lock into place with the base and unlock based on manipulation of a recessed button. Inserts can engage the base with staged gate opening to minimize chances of electrical shock.

Abstract: Techniques for header encoding include encoding a plurality of bits using a forward error correction code, generating an FEC codeword comprising a plurality of encoded bits, and concatenating a first copy of the FEC codeword with a second copy of the FEC codeword, wherein the concatenating comprises cyclically shifting by two bits the second concatenated copy of the FEC codeword relative to the first concatenated copy of the FEC codeword, wherein the encoded bits of the first and second copies of the FEC codewords are modulated on at least one OFDM symbol. techniques for header decoding include receiving a plurality of encoded bits comprising at least two concatenated copies of an FEC codeword, decoding a first copy of the FEC codeword to generate a first plurality of decoded bits, and decoding a second copy of the FEC codeword to generate a second plurality of decoded bits.

Abstract: A non-transitory computer-readable information storage media for use within a wireless OFDM network that causes to be transmitted or received a first packet type and a second packet type. The first packet type has a header field with two parts with each part comprising a different set of header bits. The two parts of the header field are transmitted or received using two OFDM symbols. The second packet type has a header field with four parts with the first and second parts comprising the same first set of header bits and the third and the fourth part comprising the same second set of header bits. The four parts of the header field are transmitted or received using four OFDM symbols. The second packet type provides more reliable transmission or reception than the first packet type.

Abstract: Disclosed is an electrical transformer for improved transformer power capacity and efficiency designed by the application of disclosed design considerations. One embodiment design consideration is a method to configure power transformer windings wherein the minimum distance of the primary windings from the winding axis/core center is greater (the primary windings are more distal) from the winding axis than the minimum distance of the secondary windings, which are wound around the minimum interior core diameter. This design consideration is extended from single bobbin transformer designs to split bobbin designs, with the requisite distal increase of the primary windings (from the core axis) geometrically provided by an enlarged core bobbin center leg (axial) dimension beneath the primary winding window.

Abstract: A wireless OFDM transceiver uses subcarrier characteristics, such as phase and amplitude, to detect the bandwidth of a received packet. By detecting different subcarrier characteristics in the long training symbols of a packet at the receiver, the packet is associated with different bandwidths. The different bandwidths are used in a wireless network where devices can communicate using different frequency bands that overlap one another and where one is wider than the other.
