Abstract: Systems and methods are described for transmitting data over physical channels to provide a high bandwidth, low latency interface between a transmitting device and a receiving device operating at high speed with low power utilization. Communication is performed using group signaling over sets of four wires using a vector signaling code, where each wire of a set carries a low-swing signal that may take on one of four signal values. Topologies and designs of wire sets are disclosed with preferred characteristics for group signaling communications.

Abstract: A communications system receiver is described providing automatic timing adjustment of receive data sampling. A concurrently received clock signal is used as both a reference for generation of internal receiver timing signals, and as an exemplar for adjustment of those timing signals to optimize received data sample timing.

Abstract: Vector signaling codes providing guaranteed numbers of transitions per unit transmission interval are described, along with methods and systems for their generation and use. The described architecture may include multiple communications sub-systems, each having its own communications wire group or sub-channel, clock-embedded signaling code, pre- and post-processing stages to guarantee the desired code transition density, and global encoding and decoding stages to first distribute data elements among the sub-systems, and then to reconstitute the received data from its received sub-system elements.

Abstract: Systems and methods are described for transmitting data over physical channels to provide a high bandwidth, low latency interface between integrated circuit chips with low power utilization. Communication is performed using group signaling over multiple wires using a vector signaling code, where each wire carries a low-swing signal that may take on more than two signal values.

Abstract: Systems and methods are described for transmitting data over physical channels to provide a high speed, low latency interface such as between a memory controller and memory devices with significantly reduced or eliminated Simultaneous Switching Output noise. Controller-side and memory-side embodiments of such channel interfaces are disclosed which do not require additional pin count or data transfer cycles, have low power utilization, and introduce minimal additional latency. In some embodiments of the invention, three or more voltage levels are used for signaling.

Abstract: Vector signaling code communications systems rely on group transmission of code symbols using multiple signaling channels that must be actively monitored and adjusted to minimize differential signal characteristics. Information obtained during receive detection may be analyzed to identify channel operational characteristics during normal operation and perform non-disruptive channel adjustments. Initialization or start-up adjustment may also be performed using intentionally transmitted patterns.

Abstract: Drug delivery devices are described that include sensors and processing circuitry that can detect operating events, such as flow rates and drug delivery, in various types of inhalers, such as dry powder inhalers, metered dose inhalers, nasal inhalers and nebulisers. The information determined by the processing circuitry can be used to provide feedback to the user or can be stored or transmitted for subsequent analysis. This information can be used to improve clinical trials by providing information about the way in which the inhalers under test are being used.

Abstract: In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal transitions and reuse it on some subsequent upward signal transitions. To facilitate this energy-conserving behavior, communication is performed using group signaling over sets of wires using a vector signaling code, with the design and use of the vector signaling code insuring that energy availability is balanced with energy demand.
