Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: A method for expanding and curing formable elastomeric material 2, which is placed in the cavity 14 of a previously molded tire 10, is disclosed. The tire 10 when filled with foamable rubber material 2 is mounted on a curing rim 20 and contacted with heat to simultaneously foam and cure the elastomeric material 2 within the tire cavity 14. The curing rim 20 has a finished or a coated surface 30 that permits the cured foam filled tire 10 to be removed after curing by slipping the cured tire 10 off the coated surface 30 of the curing rim 20.

Abstract: A system for noise canceling using a single return conductor. The system employs a first unit, a full duplex communications path coupled to the first unit, and a second unit coupled to the first unit via the full duplex communications path. The full duplex communications path employs at least three conductors: a forward signal carrying conductor; a reverse signal carrying conductor; and a single return conductor. In order to perform noise canceling, the first unit may employ, for example, a first adder coupled to the reverse signal carrying conductor, and a first canceling impedance coupled between the single return conductor and a first unit ground. Similarly, the second unit 12 may employ a second adder coupled to the forward signal carrying conductor, and a second canceling impedance coupled between the single return conductor and a second unit ground.

Abstract: In a first-in-first out memory, at least one data item is stored, and a write counter is incremented in response to the storing of each data item as it is stored into the memory. A full condition counter is also incremented in response to the writing of each data item. The at least one data item is also read from the memory, and a read counter is incremented in response to the reading of each data item from the memory. An empty condition counter is also incremented in response to the reading of each data item from the memory. In order to assure that the empty and full flag signals are not generated simultaneously, the full flag signal is generated in response to a count within the full condition counter that leads a count within the empty condition counter by a first prescribed difference. The empty flag signal is generated in response to the count within the full condition counter lagging the count within the empty condition counter by a second prescribed difference.

Abstract: A subscriber unit for wireless communication with a base station in a wireless subscriber communication system includes a FIR chip, a DIF (digital intermediate frequency) chip, a single processor chip and a radio. The processor chip transcodes a digital voice input signal to provide digital input symbols; demodulates an output signal received from the base station to provide digital output symbols; and synthesizes a digital voice output signal from the digital output symbols. The FIR chip FIR filters the digital input symbols and generates timing signals for timing the transcoding and synthesizing operations in the processor chip. The DIF chip digitally synthesizes a digital intermediate frequency signal by direct digital synthesis (DDS) and modulates the digital intermediate frequency signal with the filtered input symbols to provide a modulated intermediate frequency input signal. The radio further processes the modulated input signal for transmission to the base station.
