Abstract: A method of managing a network for delivering content to a client device, where content segments are delivered over multicast to a proxy. The received segments are stored at the proxy, before delivery of those segments is made from the proxy to the client device over unicast. Whilst the proxy receives further segments over multicast, it probes the network by making unicast requests for data (dummy data or additional content segments), and receiving those segments over unicast from the content server. The multicast rate reception rate and the unicast (probe) rate are measured and a maximum network throughput is calculated as the sum of these two rates. Subsequent segments are then delivered from the proxy to the client device at the calculated maximum network throughput rate, or at some rate dependent thereon.

Abstract: An image capture device may capture multiple audio content during capture of visual content. A viewing window for the visual content and rotational position of the image capture device during capture of the visual content may be used to generate modified audio content from the multiple audio content. The modified audio content may provide sound for playback of a punchout of the visual content using the viewing window.

Abstract: A folding bicycle trailer that converts between a bicycle trailer mode, a stroller mode, and a folded mode. The trailer has a frame having a first and second side frame assemblies, and a floor assembly. Each side frame assembly has a front wheel and a rear wheel. The front wheels are removed from the frame in the bicycle trailer mode, and are connected to the frame in the stroller and folded modes. A connection arm removably connects to a bicycle in bicycle trailer mode. The connection arm is removable in the stroller and folded modes, but can be connected to the trailer in a second position in those modes. The trailer has a removable push bar for stroller mode. The first and second side frame assemblies remain vertical but move closer to one another in the folded mode.

Abstract: A renal therapy system is disclosed. In an example, the renal therapy system includes a home renal therapy machine that stores, to a log file, dates of when renal therapies were performed and a type of each renal therapy that was performed. The system also includes a server that receives the log file from the home renal therapy machine. The server compares the dates and types of performed renal therapies stored in the log file to a device program that specifies dates for performing renal therapies and the types of renal therapies to be performed. The server displays a flag in a user interface of a clinician computer when there is a deviation from the comparison.

Abstract: Systems and methods to extend a life of a component of a cylinder deactivation system are provided. A method includes generating, by a controller, an initial life factor for the component; initiating, by the controller, a CDA mode for an engine; determining, by the controller, an actual life factor for the component, the actual life factor determined by comparing a number of switching events of a cylinder in the CDA mode to a number of cycles of the cylinder in the CDA mode; comparing, by the controller, the actual life factor to the initial life factor; and modifying, by the controller based on the comparison, operation of the engine in the CDA mode to adjust the actual life factor.

Abstract: A lighting fixture arranged and configured to emit visible (e.g., white) light and ultraviolet light. In one embodiment, the lighting fixture includes one or more visible light emitting compartments and one or more ultraviolet light emitting compartments for housing the visible light emitting components and the ultraviolet light emitting compartments, respectively. A shield is positioned between the visible light emitting compartment(s) and the ultraviolet light emitting compartment(s). The shield being configured to enable the visible light to pass therethrough while prohibiting the ultraviolet light from passing therethrough. Thus arranged, the visible light is allowed to enter the ultraviolet light emitting compartment(s) and mix with the ultraviolet light, while the ultraviolet light is prevented from entering the visible light emitting compartment(s) where it may degrade the components and materials of the visible light emitting compartment(s) contained within.

Abstract: Described is a method of delivering content over a network using an approach referred to as “Multicast Assisted Unicast Delivery” (MAUD), as a multicast network is used to assist, rather than substituting for, an otherwise unicast path. Content is requested by client devices from a content server over unicast. The responses containing the requested content are separated into two components: a first component containing elements that are specific to individual client devices (for example session specific data), and a second component that is common to all client devices (typically this is the video content being requested). The first component can be delivered over unicast and the second component over multicast. Identifiers are introduced into each of the first and second components to aid recombination of the components to form the original responses. The separation and recombination are handled by suitably configured proxy servers.

Abstract: Systems of presenting environmental data include a frequency emitting device, a frequency receiving device, wherein the frequency receiving device is tuned to receive a reflected signal from the frequency emitting device, a processor, and a sound emitting device adapted to play a sound transmission. The processor is programmed to compile data from the reflected signal and convert the data from the reflected signal into a sound transmission.

Abstract: Described is a method of delivery of content to a client device. In particular, the method can be applied to hybrid unicast/multicast delivery networks, where content is provided by a content server to a root proxy, and that root proxy delivers the content to edge proxies over multicast. However, requests for that content in the form of HTTP GET requests from a client device are received by an edge proxy, which subsequently sends an HTTP HEAD request for header information associated with that content directly to the content server. The content server responds over unicast with a suitable response to the HTTP HEAD request, which is received by the edge proxy. The edge proxy takes the response together with the payload from the content segment received over multicast, to generate a client specific content segment for delivery to the client device over unicast.

Abstract: A method of managing a network for delivering content to a client device, where content segments are delivered to a proxy in a multicast group, before delivery from the proxy to the client device over unicast. The proxy intermittently leaves the multicast group to probe the network by making unicast request for content segments, receiving those segments over unicast from the content server and forwarding those segments onto the client device. This allows the client device to determine the maximum throughput between the content server and the client device via the proxy, and thus the client device can use its adaptive bit rate algorithms to determine if the network can support a switch to a higher bit rate stream, and request a higher bit rate stream accordingly. The higher bit rate stream can be serviced by the proxy joining or establishing a suitable multicast group.

Abstract: Described is a method of managing a network for delivering content in a hybrid unicast/multicast network, where content is requested by clients over unicast, but all or some of the content is delivered in part over multicast. A client requests content (in the form of segments) and receive the responses (segments) over unicast via a first proxy. The first proxy measures the time between requests and associated requested segment sizes. These measurements are used to effectively determine a unicast request rate given by the segment size divided by the time between requests. Subsequent requested segments can then be delivered over multicast over a portion of the route to the client using a multicast rate that is set as a function of (for example, 110% of) the unicast request rate. In general, the multicast path will be from a second proxy to the first proxy.

Abstract: Described is a method of managing a network for delivering content in a hybrid unicast/multicast network, where content is requested by clients over unicast, but all or some of the content is delivered in part over multicast. Typically, a client requests content (in the form of segments) via a first proxy. The segments are delivered to the first proxy over multicast from a second proxy, before onward transmission to the requesting client over unicast. The segments are also cached at the first proxy, and can be transmitted over unicast to other clients requesting those segments. However, problems can arise if cached segments are transmitted to clients too quickly. In one solution, the first proxy measures the multicast rate of delivery of segments from the second proxy over multicast, and limits the transmission rate of those segments over unicast to requesting clients to no greater than the measured multicast delivery rate.

Abstract: Presented are methods for converting a multicast media stream to unicast segments, for delivery over generic IP networks such the Internet. The unicast segments can be converted back again to a multicast stream that is identical to the original multicast stream closer to the consuming client device. Information required to regenerate a multicast stream from the generated unicast segments that is identical to the original multicast stream is also encoded into the file name of the generated unicast segments. Additionally, RTP header information from the multicast stream that is not required when the unicast segments are generated are stored in files linked to the generated unicast segments, enabling the multicast stream that is regenerated to be identical to the original multicast stream even at the RTP level.
