Abstract: Bluetooth Low Energy nodes are serially-connected with a cable that includes power lines and can include communication wires. The nodes do not have individual batteries. Instead, a single common power source is connected to the wires to provide power for all the nodes. The nodes can also be connected in series with the communication wires (which can be the same as the power wires) along a length of the cable. A headend interface can also be connected at one point of the cable to provide a communication interface with the nodes. The nodes can transmit and/or receive beacons to be used for locationing of mobile devices.

Abstract: Apparatus and method for communicating high-speed signals between a primary printed circuit board and one or more secondary printed circuit boards. The high-speed signals are communicated between the primary printed circuit boards and the secondary printed circuit boards through multi-layer flexible conductors.

Abstract: A baseband signal is spectrally efficiently transmitted on a broadband transmission medium by inserting gaps in packets of digital data transmitted in a modulated first radio frequency carrier. The transmitted packets of data are received by demodulating the modulated first radio frequency carrier, and the gap is monitored for the presence of digital data thus indicating a collision of simultaneously transmitted packets of digital data. A seed of arbitrary digital bits are used in scrambling each packet of digital data and is transmitted with the packet of data for use in descrambling the data. In retransmitting the packet of data the seed is included. The originally transmitting node receives the retransmitted packet and compares the retransmitted seed with the originally transmitted seed for detecting an error in retransmission.

Abstract: Apparatus for combining broadband RF signals and baseband signals in a baseband distribution cable includes a bridge for coupling the distribution cable to an RF broadband trunk and to a baseband repeater. The trunk is connected through bidirectional amplifier, an impedance transformer, and a signal splitter for applying the amplified and impedance transformed broadband signal to a plurality of baseband segments. The RF signal from the splitter is passed through a 35 MHz high pass filter to the baseband segment. Baseband signals from a repeater are passed through a 25 MHz low pass filter to the baseband segment. The two filters prevent interference between the baseband and broadband signals.
