  • Publication number: 20250009959
    Abstract: Electronic patient monitoring and treatment devices can include various loads (such as, pumps or sensors) that may need to be actively managed at startup to prevent a brownout condition and reset from occurring. To prevent the brownout and reset, an initial inrush current to the load can be limited by a soft-start circuit. In some cases, alternatively activating and deactivating a switch can packetize the energy transfer from a power source to the load and reduce the inrush current. Reducing the current can also reduce the required recovery time of the power source.

  • Patent number: 11554776
    Abstract: A system and a method for the determination and forecast of absolute and relative risks for car accidents based on exclusively non-insurance related measuring data and based on automated traffic pattern recognition, wherein data records of accident events are generated and location-dependent probability values for specific accident conditions associated with the risk of car accident are determined. The proposed system provides a grid-based, technically new way of automation of risk-prediction related to motor accidents using environment based factors including socio-economic factors that are impacting motor traffic and are location dependent received from appropriate measuring devices and systems. In this way, predictions of the accident risk for arbitrary areas can be provided. The system is calibrated by comparing features of areas or road segments with the number and type of accidents that have measured or registered there, linking the features and accident data e.g.

  • Patent number: 10850731
    Abstract: Proposed are a measuring apparatus (1) and a measuring method for automated traffic and driving pattern recognition and location-dependent measurement and forecast of absolute and relative risks for car accidents based on exclusively non-insurance related measuring data and based on automated traffic pattern recognition and associated with the traffic and driving pattern providing a high degree of temporal and spatial resolution. The proposed apparatus (1) provides a grid-based (2121, 2122, 2123, 2124), technically new way of automation of automated traffic and driving pattern recognition and risk-prediction related to motor accidents using environment based factors (elevation, road network, traffic data, weather conditions including socio-economic factors) that are impacting motor traffic and are location dependent received from appropriate measuring devices (41, . . . , 45). In this way, predictions of the accident risk for arbitrary areas can be provided.

  • Patent number: 10355979
    Abstract: The invention relates to sending media packets, such as SIP or RTP, via a media forwarding element which includes an anycast interface having an address shared with other media forwarding elements. If network topology changes or a media forwarding element becomes unavailable, then anycast messages may be routed to a different media forwarding element sharing the same anycast address. The new media element can then take over handling of the call from the first one.

  • Patent number: 9641561
    Abstract: A method, system and computer program product are described for managing network communications to a Session Initiation Protocol (SIP) server capable of SIP processing using a SIP stack. A data packet is received from a network device. It is determined, from the data packet, whether the network device is a device recognized by the SIP server. Responsive to this determination, and before SIP processing using the SIP stack, it is determined whether the data packet conforms to a permitted configuration. The permitted configuration includes that data of the data packet indicates an unfragmented User Datagram Protocol (UDP) packet and that data indicative of SIP data in the received data packet matches a parsing rule. If the data packet conforms to the permitted configuration, it is passed to the SIP stack, if not it is discarded.

  • Patent number: 9497108
    Abstract: Measures for enabling media bypass of one or more session border controllers (SBCs) in a telecommunications network which includes a plurality of SBCs. An SBC receives an inbound offer message requesting setup of a media session between an originating endpoint device and a terminating endpoint device. The SBC transmits an outbound offer message to an ensuing SBC, wherein the originating endpoint device address comprised in the inbound offer message is re-written with an SBC address in the outbound offer message. The SBC receives an inbound answer message including a terminating endpoint device address. In response to receipt of the inbound answer message, the SBC transmits an outbound answer message to the originating endpoint device without re-writing the terminating endpoint device address, whereby the SBC and the ensuing SBC are bypassed in the media path for the media session.

  • Patent number: 9037729
    Abstract: There is provided a system, method and computer program product for managing network communications to a Session Initiation Protocol (SIP) server. In the system, a packet limiter receives packets relating to SIP messages from a network and selectively forwards said packets for initial SIP processing. A work scheduler then accesses the result of the initial SIP processing and determines whether to proceed with further SIP processing based on a level of system activity. If a level of system activity is such that the system should proceed with further SIP processing, then further SIP processing may be scheduled. Initial SIP processing may involve one or more of parsing, request handling and response handling. Further SIP processing may involve one or more of initiating a new dialog, processing SIP messages relating to an existing dialog and processing messages that do not require a dialog.
