Abstract: A modular wearable health monitor having a substantially flexible attachment means connected to a housing comprising a power source and at least one processor through a relatively rigid and narrow spine disposed substantially centrally thereon having a variety of clinical and non-clinical uses that provides more comfortable and durable attachment of biometric sensors to a user by allowing the attachment means to contour to the user's body without the housing also being forced to do so along its entire width.

Abstract: A system and method for using algorithms and acoustic input to control, monitor, annotate, and configure a wearable patch that monitors physiological signals. The method comprises the receiving a transmission at a wearable device wherein the transmission can identify a mode of operation, an annotation to the data in the device, a request for data from the device, a modification of the configuration of parameters, and signals in the device.

Abstract: A data system architecture is described that allows multiple processing and storage resources to be connected to multiple clients so as 1) to distribute the clients' workload efficiently across the available resources; and 2) to enable scaleable expansion, both in terms of the number of clients and in the number of resources. The major features of the architecture are separate, modular, client and resource elements that can be added independently, a high-performance cross-bar data switch interconnecting these various elements, separate serial communication paths for controlling the cross-bar switch settings, separate communication paths for passing control information among the various elements and a resource utilization methodology that enables clients to distribute processing or storage tasks across all available resources, thereby eliminating “hot spots” resulting from uneven utilization of those resources.

Abstract: A procedure is described for determining which source to connect to which destination in a non-blocking crossbar switch through which a plurality of sources may be attempting to gain access to a plurality of destinations. To this end, a metric is dynamically associated with each source and with each destination. Matching of sources to destinations is accomplished by iteratively assigning the destination having the smallest metric of all currently unmatched destinations to the source having the smallest metric of all currently unmatched source.

Abstract: An apparatus and method for determining the QoS of a communication system. In one embodiment a service verification equipment device (SVE) is placed into the communications link between the wide area network and the transmitting customer premise and an SVE is placed into the communications link between the wide area network and the receiving customer premise. The transmitting SVE inserts a test cell into the customer's data stream over communications link which informs the receiving SVE that a test is commencing. After a predetermined number of customer data cells are sent, the transmitting SVE inserts a termination cell into the communications link at the end of the test. The receiving SVE then compiles data related to the QoS of the communications link and that data is analyzed to determine the QoS.

Abstract: An improved local area network ring node of the type described in ANSI/IEEE Standard 802.5, including a receiver having an input connectable to the ring, a phase-locked loop circuit for extracting a clock frequency from the receiver output and including a phase detector for generating a phase error signal, and a data demodulator connected for demodulating at the extracted clock frequency the data in the receiver output. The improvement lies in the provision of a filter for deriving a control signal from the outputs of the data demodulator and the phase detector and an adaptive equalizer for reducing the effect of jitter in signals applied to the receiver input from the network, the equalizer comprising a filter network including a voltage variable impedance so connected as to vary responsively to the control signal.
