Abstract: The electronic audio connection system of the present invention provides an experience much like sharing a room with several involved parties, even though the parties are physically separated. Speech enhancement and speech emphasis processing functions ensure parties perceive the speech captured in the audio signals, typically the most important portion of the captured audio signals. To capture audio signals, each space is provided a plurality of microphones arranged in that space so that the sum audio signal captured by the microphones enables the creation of a sharable audio space. Each separate physical space transmits its captured audio signals to a central server via a bi-directional data communications medium. The central server processes the summed audio signals and in turn transmits playable audio signals to each separate physical space. Speakers located in each separate physical space aurally transmit the playable audio signals.

Abstract: A method and apparatus for generating a baseband signal from a data pulse to approximate a filter transfer function is disclosed. The method comprises generating the data pulse, generating a plurality of delayed short pulses from the data pulse, and generating an output baseband signal from the of delayed pulses. The apparatus for generating a baseband signal from a data pulse to approximate a filter transfer function, comprises an input node coupled to the data pulse, an output node, a pull-up circuit coupled to said output node which generates positive going excursions of the baseband signal, and a pull-down circuit coupled to said output node which generates negative going excursions of the baseband signal.

Abstract: The invention enables “low attention recording,” i.e., recording that need not appreciably affect interaction of a recorder (i.e., a person in control of a recording unit according to the invention) or others with the environment in which the recording is taking place. The low attention recording enabled by the invention can be particularly advantageously employed in “social recording,” i.e., recording in which multiple participants in an event are recording the event. As described in more detail below, advantageous aspects of the invention can be provided by a small, lightweight, wearable recording unit. In particular, a recording unit according to the invention is particularly adapted to enable use of the recording unit to record an event during which the recorder engages in vigorous physical activity (e.g., an athletic activity, such as hiking, snow skiing or ping pong).

Abstract: A decentralized network that transmit data between devices using UWB signals. A device needing a data transmission participates in a contention phase after the system is idle for a predetermined amount of time. The device then generates a packet that includes a control header having synchronization data and transmits the packet to a receiving device.

Abstract: A method which allows for operating a baseband transmitter and provides reduced interference to a narrowband receiver having a passband around a frequency f. The baseband transmitter generates pulses at a nominal pulse repetition rate having at least one harmonic falling within the passband of the narrowband receiver, and then continuously varies the nominal pulse repetition rate in amounts such that the average time that the harmonic falls within the passband is less than 100%.

Abstract: A broadband transmit/recieve antenna apparatus which operates at high frequencies and provides for two separate wideband tapered notch regions formed on one coplanar substrate. The tapered notch regions function as radiators for the transmission and reception of electromagnetic signals. The simple and compact design for the broadband antenna permits the transmission and reception of high frequency omnidirectional or directional radiation patterns. The broadband antenna interfaces with an an integrated circuit such as an ASIC which provides a series of pulsed signals and is resident on the antenna. The design of the broadband antenna provides for an optional stop notch to separate the transmitting portion of the antenna from the receiving portion of the antenna. Additionally, the antenna provides for impedance matching by locating transmission lines at an appropriate location with respect to the tapered notch radiators.
