Patent number: 11850076Abstract: Apparatuses and methods are provided for automatically determining which type of resuscitation treatment is most appropriate for a patient. Methods are provided that include the following. One or more time domain signal measurements are transformed into frequency domain data representative of a frequency content of the one or more time domain signal measurements. The frequency domain data is processed to identify peaks. For each of the peaks, for each of multiple points in time, multiple parameters of the peak are determined. Based on the multiple parameters of the peaks for each of the multiple points in time, a trajectory is determined. The determined trajectory is analyzed in determining a recommended type of resuscitation treatment. An output indication is provided of the recommended type of resuscitation treatment.Type: GrantFiled: October 28, 2020Date of Patent: December 26, 2023Assignee: ZOLL Medical CorporationInventors: Gary A Freeman, James E Brewer

Patent number: 10148706Abstract: An ingress call filter system enables real-time or near real-time efficiencies of an inter-carrier switch. The ingress call filter determines if a received call to a called party is likely to fail. If the call is likely to fail, the ingress call filter returns an indication that the call should be filtered or rejected. If the call in not likely to fail, the ingress call filter returns an indication that a call router should attempt to establish the call. Such techniques mitigate penalties assessed to the inter-carrier network for incomplete or failed calls in real time or near real time.Type: GrantFiled: January 9, 2015Date of Patent: December 4, 2018Assignee: PEERLESS NETWORK, INC.Inventors: James E. Brewer, Jeffrey S. Wall

Patent number: 9736197Abstract: A method of extending calls includes receiving a request to establish a call session with a called party, and establishing the call session between the calling party and the called party. The method further includes monitoring the length of the established call session, and receiving a message requesting a termination of the call session. Still further, the method includes, in response to receiving the message requesting the termination of the call session, maintaining the established call session for an additional time period, wherein the additional time period plus the monitored length of the established call session is equal to or greater than a threshold of time.Type: GrantFiled: February 27, 2015Date of Patent: August 15, 2017Assignee: PEERLESS NETWORKS, INC.Inventors: James E.

Patent number: 9729586Abstract: To maximize efficiencies and to reduce termination costs of inter-carrier exchanges, an auto-dialer detection system enables an inter-carrier network switch to detect, in real-time or in near real-time, calls that are originated by auto-dialers. A call router of the switch may receive an incoming call attempt that includes a particular Automatic Number Identification (ANI). The auto-dialer detection system allows for a real-time or near-real time determination, based on the ANI and contents of a cache during a sliding window of time coincident with the reception of the origination, whether or not the call should be routed through the switch. Further, the auto-dialer detection system provides a real-time or a near real-time update to the cache contents to enable further real-time or near-real time detection and blocking of auto-dialed calls. Overrides to the cache (e.g., to always allow and/or to always block calls that include certain ANIs) may be provided.Type: GrantFiled: November 17, 2014Date of Patent: August 8, 2017Assignee: PEERLESS NETWORKS, INC.Inventors: James E. Brewer, Jeffrey S. Wall

Patent number: 9706351Abstract: Techniques for originating an emergency call over a data network include determining whether or not a location services are currently available. Call control may be released to the native dialer when the location services are currently unavailable. Otherwise, the call may be processed by the application dialer, and may be routed from the mobile device towards a Public Safety Answering Point (PSAP) by using a private packet backbone network exchange. The application dialer may be configured to utilize a packet header format that indicates a geographic location of the mobile device when communicating with an emergency call router interconnected with the private packet backbone network exchange.Type: GrantFiled: April 29, 2016Date of Patent: July 11, 2017Assignee: PEERLESS NETWORK, INC.Inventor: James E.

Patent number: 9705939Abstract: A vendor evaluator system enables real-time or near real-time efficiencies of an inter-carrier switch. At a nominal periodic rate (e.g., every fifteen minutes or less), the vendor evaluator system updates a performance map of vendor exchanges to which calls may be routed from the switch. Specifically, in real-time or in near real-time, an updated performance score is generated for each vendor exchange and/or for each NPA-NXX code that is connected to the switch based on a weighted average of post dial delay, average call hold time, and attempt-seizure ratio. The score is compared against performance thresholds to determine whether or not the respective exchange and/or code should be included in a pool of acceptably-performing, candidate vendor exchanges from which a particular exchange is selected to service a call. Such techniques prevent poorly performing vendors from servicing calls routed by the inter-carrier network switch in real time or near real-time.Type: GrantFiled: November 13, 2014Date of Patent: July 11, 2017Assignee: PEERLESS NETWORK, INC.Inventors: James E.
