Abstract: Methods and systems for processing audio information to identify persons of interest in regard to a public-safety incident. An example method includes receiving human-generated narrative statements as audio and converting the narrative statements into corresponding digital texts. The method further includes determining incriminating scores for each of the narrative statements by identifying, in the digital texts, incident information classified as not being publicly known. The method further includes determining a cumulative score for an individual based on the incriminating scores tagged to the individual, making a determination of whether the individual is a person of interest based on a comparison of the cumulative score with a fixed threshold, and performing at least one automated responsive action based on the determination.

Abstract: A stable dispersant and an application thereof in preparing copolymer polyols, the preparation method for the stable dispersant including the steps of 1) contacting a polyol with a dianhydride compound for reaction so as to prepare an adduct; 2) performing a ring-opening addition reaction on the adduct obtained in step 1) and an epoxy compound to prepare a stable dispersant; the dianhydride compound does not contain a double bond that may copolymerize with an olefinically unsaturated monomer, while the epoxy compound contains a double bond that may copolymerize with an olefinically unsaturated monomer, the polyol is a polyester polyol and/or a polyether polyol, preferably being a polyether polyol. The stable dispersant obtained by means of the described preparation method has a multi-active site anchoring function, and is applied to the synthesis of copolymer polyols to obtain copolymer polyols having relatively uniform particle size.

Abstract: A method and apparatus for aiding a police officer in writing a report by creating a depiction of an incident scene is provided herein. During operation a drone will photograph an incident scene from above. Relevant objects will be identified and a depiction of the incident scene will be created by overlaying the relevant photographed real world objects onto a map retrieved from storage. The depiction of the incident scene will be made available to police officers to increase the officers' efficiency in report writing. More particularly, officers will no longer need to re-create the depiction of the incident scene by hand. Instead, the officer will be able to use the depiction of the incident scene.

Abstract: The present application relates to the technical field of polyaryletherketone, and discloses a preparation method for a coating material containing high-temperature self-crosslinking fluorine-containing polyaryletherketone. A molecular chain of the high-temperature self-crosslinking fluorine-containing polyaryletherketone contains two crosslinking groups of a styrene group and a thioether group, and its structural formula is: Herein, the value range of m is 1-40%, the value range of n is 60-99%, and R is a group that removes a phenolic hydroxyl group from hexafluorobisphenol A. In the high-temperature curing process after film coating, the crosslinking reaction occurs to form a crosslinked polymer coating layer, thereby a coating surface with good moisture and heat resistance, wear resistance, and low friction coefficient is formed.

During operation talkgroups within a communication system will be assigned to particular network slices. Some network slices may have a single talkgroup assigned to them, and other network slices may have multiple talkgroups assigned to them. During operation, communication-system infrastructure will conduct all communications for a group of devices over a particular talkgroup via a particular network slice.

Abstract: A process of detecting signal interference among geographically co-located radios affiliated with different talkgroups, An electronic computing device receives a log of push-to-talk (PTT) operations performed at a first radio and a log of audio quality values measured corresponding to audio communications received at a second radio. The first radio is affiliated with a first talkgroup and operates on a first channel frequency assigned to the first talkgroup. The second radio is affiliated with a second talkgroup and further operates on a second channel frequency assigned to the second talkgroup. The device detects that signal interference at the second radio is potentially caused by the first radio when there is a time correlation between a PTT operation performed at the first radio and a change in audio quality at the second radio and when the second radio was geographically co-located with the first radio during the time correlation.

Abstract: A system, method, and apparatus for implementing workflows across multiple differing systems and devices is provided herein. During operation, a graphical-user interface provides a user with a list of triggers and a list of actions. A user creates a workflow by dragging a trigger and at least one action to an area of a screen (workspace) and then connecting them with a line or arc. If a security ecosystem is unable to execute the created workflow, the necessary components needed to execute the workflow will be provided in a small area on the screen (workspace).

Abstract: A portable radio is provided that performs an impedance measurement to determine a radio frequency (RF) load type connected to an antenna port of the portable radio. The portable radio includes an impedance measurement circuit and a tunable matching circuit operatively coupled thereto through an RF switch A sweep generator injects an LMR frequency sweep to the RF load during non-transmit or non-receive time slots for the impedance measurement. The tunable matching circuit is configured as a radio frequency (RF) bypass during the impedance measurement, thereby enabling the impedance measurement circuit to directly measure the impedance of the RF load coupled to the RF port and identify the RF load as either a land mobile radio (LMR) antenna or equipment (wideband load). When the RF load is determined to be an LMR antenna, then the matching circuitry is tuned for the identified antenna. When the RF load is determined to be wideband equipment, then the matching circuitry remains bypassed.

Abstract: A device, system and method for routing botnet calls to a botnet call-answer queue. A device, such as a call answering point (CAP) and/or a public-safety answering point (PSAP) router device, receives a call and determines an audio signature of the call. The device compares the audio signature of the call with one or more botnet audio signatures stored at a memory. In response to the audio signature of the call matching at least one of the one or more botnet audio signatures, the device: identifies the call as a botnet call that has been placed by a botnet; and cause the call to be routed to a botnet call-answer queue.

Abstract: A system, method, and apparatus for implementing workflows across multiple differing systems and devices is provided herein. During operation, a workflow is automatically generated based upon a high probability of overloading resources with a current workflow. In particular, a workstation (or server) detects a high probability that a resource will be overloaded if a particular trigger is implemented. The workstation (or server) then determines an alternate trigger to reduce the chances that a resource will be overloaded. The alternate trigger and action can then be implemented or suggested as a newly-created workflow.

Abstract: A method and apparatus for writing a report is described herein. During the process an officer will acquire an image of an incident scene. The image may comprise a live image, a video, or a still image (picture). Potential objects of interest will be highlighted within the image for selection by the officer. When an object of interest is selected (e.g., touched on a touch screen), a description of the object of interest will be inserted at a point in a report where a cursor lies. The user will also be allowed to transcribe (via speech to text) their report, and have text representing their speech inserted where the cursor lies.

Abstract: A system, method, and apparatus for implementing workflows across multiple differing systems and devices are provided herein. During operation a workflow is automatically generated upon the detection of new device capabilities. In particular, a workflow server will detect the presence of new device capabilities in a particular area. The new device capabilities will be analyzed, and an appropriate trigger and action will be determined based on the new device capabilities. The appropriate trigger and action will then be implemented as a newly-created workflow.
