  • Patent number: 11998340
    Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

  • Publication number: 20240163646
    Abstract: In an example, a request is received from a first user equipment (UE). The request corresponds to a request to establish a communication session with a second UE. A location of the first UE is determined based upon the request. An event datastore is analyzed, based upon the location of the first UE, to identify one or more events potentially impacting telecommunication services provided to the first UE. Based upon the one or more events, an announcement is provided for presentation on the first UE.

  • Patent number: 11930133
    Abstract: A device may determine that a failure occurred in an emergency call between a public-safety answering point (PSAP) and a first user device associated with an emergency caller, and may identify, based on determining the failure, one of a first option, a second option, or a third option for redirecting an emergency callback to a contact of the emergency caller. The device may cause, when the first option is identified, the emergency callback to be redirected to a second user device associated with the contact of the emergency caller, and may cause, when the first option is identified, a bearer path to be established between the PSAP and the second user device for the emergency callback.

  • Patent number: 4201485
    Abstract: An apparatus for continuously mixing liquid resin and powdered hardeners in accurate proportions to produce adhesives is described. A mixing screw and tube lock into a mounting from which they may easily be removed for quick cleanout. The preferred screw has mixing threads that are of the buttress type, having rectangular leading and sloped trailing edges in cross section. The screw is divided into transporting and high shear rate mixing sections. In the transporting section, the rectangular thread edges face in the direction of material flow through the tube. The high shear rate section's buttress threads are modified by spiral cuts in the threads, at a greater lead than the buttress threads. This section is installed with the sloped edge facing the direction of material flow.
