Abstract: A non-systematic convolutional decoder of a convolutionally encoded multi-level data stream includes a shift register and two or more paths of exclusive-OR (XOR) gates, arranged to reconstruct an original input information stream, each path having a quantiser arranged to quantise the signal to two levels, and a set of XOR gates arranged to match an encoding path in an associated convolutional encoder, and a selector arranged to feed an output from each path to a single input of the shift register. If the paths have differing values at their output, the selector may choose the value from the path based upon a function of the multi-level signals associated with each path, such as the path with the largest absolute signal level. The decoder provides a simple means for decoding signals while allowing the signal to also or instead be decoded using e.g. a Viterbi decoder if higher performance is required.

Abstract: A system for compensating for phase noise, with particular application in lidar, includes a compensation interferometer that receives a signal from a source, and splits it into a first and second path, with a path length difference ?? between them. Typically the path length is significantly less than that of the return distance to a target. The output of the compensation interferometer, which consists of phase noise generated in time ?? is vectorially summed during a time similar to a signal flight time to a target, and the result used to reduce phase noise present on measurements of a target. It further includes means for selecting ?? such that competing noise elements are reduced or optimised.

Abstract: A radio receiver includes a downconverter for downconverting dual sideband signals such as Binary Offset Carrier (BOC) signals from multiple sources to produce an upper and a lower sideband signal, and chip-matched filters for filtering each of the sideband signals. The output of each filter is provided to a series of separate channels, one for each source, where there are at least Early, Prompt and Late gates. Each gate has a nearest-neighbour sampler and a multiplier for multiplying with an appropriate part of a spreading code, a mixer for removing Doppler or other frequency offsets and an integrator. The invention provides a means for demodulating signals such as BOC modulated satellite navigation signals in an efficient manner by using a single downconverter for the received signals of interest from the multiple sources.

Abstract: Participant-provided qualitative or comment-style responses to inquiries may be processed to generate processed responses, which may then be evaluated by participants for ranking. The processed responses may reflect groups of similar qualitative responses to, among other things, simplify and reduce the amount of data that needs to be reviewed by the participants for ranking. On the other hand, the processed responses may have a one-to-one correspondence with the qualitative responses, and the grouping of similar responses may occur after the participant ranking. Grouping after participant ranking may have the benefit of, among other things, simplifying the grouping, as only highest ranked responses may need to be grouped.

Abstract: A method for the reception of a frequency hopped direct sequence spread spectrum signal includes acquiring the signal by splitting the received signal into a plurality of processing sub-channels, each corresponding to one or more hop frequencies; and within each sub-channel: i) subtracting any sub-carrier frequency from the received signal; ii) filtering the signal from (i) using a chip-matched filter; iii) selecting a sub-set of samples from the filtered signal; iv) correlating the sampled signal from step (iii) with a known reference signal to produce at least one correlator output. The output(s) from each sub-channel are provided to an input of a corresponding one or more common discrete time Fourier transforms (DTFT), and an output therefrom having a peak above a predetermined threshold is selected for further processing in the receiver. The method is a less expensive way of tracking the signal and can demodulate appropriately modulated signals.

The method comprises monitoring the predefined frequency band at a first location to identify an emission of an interfering signal from a passing vehicle. If an interfering signal is detected, the method further comprises capturing a first image of the passing vehicle to enable an identity of the passing vehicle to be determined.

Abstract: Systems and methods for defining a composite view and using the definition of the composite view to obtain, aggregate, analyze, and present data from a variety of data sources to a user. These systems and methods may allow for the definition of a visual framework to aggregate and display related data. This visual framework, or composite view, may in turn be composed of a master view and a set of subviews, each of which may display data collected from a particular data source according to a particular format. By interacting with the master view data from a variety of data sources can be displayed.

Abstract: The sharing of objects may be executed by performing various share type administrations. Objects may be shared directly to a site or may be made available indirectly for reuse by a site. The objects shared and made available for reuse may be added to the site to which they are shared and made available for reuse. References to the objects shared and made available for reuse are stored in repositories in response to, and in accordance with, the share type administration performed. The storage of the references to objects is based on privileges associated with at least one of a repository, a site and a user. Objects made available for reuse by, and shared to, a site may be made unavailable for reuse by, and unshared to, the site through the execution of a share type administration.

Abstract: A method for coordinating medical treatments and in-care patient tracking system is set forth wherein a patient peripheral enables determination of patient location data, patient identification data, and treatment data, by sensed spatiotemporal relationships of the patient peripheral within a designated area. Proximity of the patient peripheral with a practitioner peripheral enables automated association of treatment data to a patient record alongside practitioner identification data. Treatment data generated, such as collected samples and other data, effects automatic assignment of the patient identity to relevant data and materials. Inventory is trackable, and doses administered are reportable automatically to the patient record.

Abstract: A practitioner network and appointment management system is presented that coordinates between end users and practitioners to enable networked appointment scheduling and management. The system includes an end user side and a practitioner side. End user side enables control of a scalable interactive map whereon practitioner data points are displayable by medical discipline. Practitioner first order data (including time to availability) is visually cued. Selection of a practitioner data point enables end user entry to a practitioner queue, which updates practitioner first order data across the network. Patient data is automatically transferrable to the practitioner queue by secure protocol. Practitioner side enables access of practitioner queue and selection of patients occupying designated slots therein to view associated patient data. Patient locations are displayable to practitioner for in-person visits. Practitioners can transfer patients into other practitioner queues.

Abstract: A practitioner network and patient coordinated healthcare system devised to enable secure and private handling of a patient history as a single Electronic Coordinated Care Portfolio (“ECCP”) accessible through a patient portal via network. Multiple caregivers are able to access partitions in a patient portal comprising a plurality of COMMs for access, upload, and, for some users, download of relevant healthcare information. Access and privileges at each of the plurality of COMMs is controllable by assignment of vertical access tiers to users. Caregivers are thus enabled a holistic understanding of care provision across all caregivers for a particular patient, while patient privacy is protected. The ECCP is encodable as a unique file format to which specific security protocols are enabled and sharing of confidential data is protectable, accessible between authorized users only.
