Abstract: A signal or lighting system synchronizes the flashing of multiple signal or lighting assemblies. When one of the assemblies is triggered, it broadcasts a temporally staggered sequence of signals, each signal instructing the receiving assemblies to initiate flashing of their beacons a given countdown time after that particular signal is transmitted. The countdown times of the various signals all count down to the same flashing start time so that the originating and receiving beacons all being flashing at the same time. The temporal diversity of the signals enhances the ability to overcome potential interference as at least one of the signals in the sequence is likely to be received by the destination assemblies.

Abstract: A method for issuing tickets in a communication system comprising a plurality of nodes that are capable of establishing a communication connection between two or more clients, the method comprising a first client transmitting to a ticket-issuing service a request for a ticket authorizing the first client to establish a communication connection with a second client, the ticket-issuing service determining if the first client is authorized to establish the requested communication connection and if the first client is determined to be authorized to establish the requested communication connection, the ticket-issuing service transmitting to the first client one or more tickets designating the second client which authorizes the first client to establish the requested connection with the second client by means of one or more of the plurality of nodes.

Abstract: A solar lighting system includes a record of a plurality of lighting profiles. The particular profile that governs the operation of the lights of the system at any given time is selected by each lighting element according to its determination of the time of year or season. The invention allows the more efficient use of solar energy collected at various time of the year.

Abstract: The present disclosure relates to an diesel exhaust treatment device including a main body having a central longitudinal axis that extends between first and second ends of the main body. A catalyzed substrate is positioned within an interior of the main body. A side inlet is positioned at a side of the main body for directing exhaust gas into the interior of the main body. A flow distribution element is positioned within the interior of the main body at a location between the side inlet and an upstream face of the substrate. The flow distribution element extends across a direction of exhaust flow through the main body and is mounted at a side of the main body that is opposite the side inlet.

Abstract: A network of lighting elements controlled by a control system, in which the control system receives and analyzes operating conditions from the lighting elements in the network, from which it can determine whether any lighting elements are operating at unacceptable levels. The analysis is carried out by averaging the values received from the lighting elements to determine a baseline value and determining whether any deviate from the baseline value by more than a pre-determined amount. Alternatively, the analysis may be done by finding the distribution of the values and mode value, and determining whether any individual values are outside an acceptable distribution.

Abstract: A communication system comprising a plurality of nodes that are capable of establishing a communication connection between two or more clients, the plurality of nodes being arranged in a hierarchy in which a node comprised in one level of the hierarchy is more likely to be reachable by a client trying to establish a communication connection with another client than a node comprised in a lower level of the hierarchy, the communication system being arranged such that, when a client determines that a node is unreachable for establishing a communication connection between it and another client, that communication connection is instead established by a node comprised in a higher level of the hierarchy than the unreachable node.

Abstract: Particle populations and assays are provided which have varying amounts of magnetic material and varying particle concentrations among different subsets of particles. In particular, the particle populations and assays include at least two particle sets with distinct sums of particles which are inversely related to the magnetic material concentration comprising each of the particles within the two particle sets, respectively. A method for processing an assay having such particle sets includes routing the assay in proximity to an imaging plane within a static imaging optical analysis system and generating a magnetic field in proximity to the imaging plane. The magnetic field is sufficient to attract and immobilize a ratio of particles from the at least two discrete particle sets that is different from the ratio of particles comprising the at least two discrete particle sets in the assay as the assay is introduced into the static imaging optical analysis system.

Abstract: Described herein is an analyte detection device and method related to a portable instrument suitable for point-of-care analyses. In some embodiments, a portable instrument may include a disposable cartridge, an optical detector, a sample collection device and/or sample reservoir, reagent delivery systems, fluid delivery systems, one or more channels, and/or waste reservoirs. Use of a portable instrument may reduce the hazard to an operator by reducing an operator's contact with a sample for analysis. The device is capable of obtaining diagnostic information using cellular- and/or particle-based analyses and may be used in conjunction with membrane- and/or particle-based analysis cartridges. Analytes, including proteins and cells and/or microbes may be detected using the membrane and/or particle based analysis system.

Abstract: The disclosure discloses a method for extending the length of time over which a cordless telephone system can operate without an external source of power. The method involves detecting a power supply outage, determining that a telephone call is not currently being handled, placing the portable unit into a mode of reduced power consumption, and placing the base unit into a mode of reduced power consumption. After a period of time, the base unit resumes functionality, determines whether a call is being initiated, and handles any such calls. If the system is not active, the base unit re-enters its mode of reduced power consumption, and the cycle is repeated.

Abstract: In a passive identification apparatus for identifying a predetermined individual member of a television viewing audience in a monitored viewing area, a video image of a monitored viewing area is captured. A template matching score is provided for an object in the video image. A Eigenface recognition score is provided for an object in the video image. These scores may be provided by comparing objects in the video image to reference files. The template matching score and the Eigenface recognition score are fused to form a composite identification record from which a viewer may be identified. Body shape matching, viewer tracking, viewer sensing, and/or historical data may be used to assist in viewer identification. The reference files may be updated as recognition scores decline.
