Abstract: Hazard detectors are shown and described. Included are devices, systems, kits, and methods for a hazard detector. A hazard detector may in some embodiments include a housing, a presence detector, a hazard detector and a control system. In some examples, hazard detector systems may include a hazard detector having one or more sensors with the ability to detect a hazard and a system for evaluating the hazard for characteristics prior to signaling an alarm. A hazard detector may include power saving systems for longevity and reliability of the detector.

Abstract: A system and related method, including a first processor core, a second processor core and a control circuitry to receive requests to update existing firmware of the first processor core to a new firmware. The control circuitry loads existing firmware onto the second processor core and migrates data associated with the existing firmware on the first processor core to the second processor core. The control circuitry stops the transaction execution by the first processor core while causing the second processor core to execute transactions in place of the first processor core. The control circuitry restarts the first processor core, replaces the existing firmware on the first processor core with the new firmware, and migrates data of the existing firmware on the second processor core to the first processor core. The control circuitry stops the transaction execution of the second processor core and causes the first processor core to execute transactions.

Abstract: To predict client sensitivity to rate changes for commercial deposit products, a machine learning model is trained using (i) first attributes associated with a corresponding first client during a first rate change, (ii) an indication of whether the first rate change was requested by the corresponding first client or by a corresponding first bank, and (iii) an indication of whether the corresponding first client is sensitive to the first rate change. A second set of attributes is obtained which is associated with a second client having a second commercial deposit product. A machine learning engine applies the second set of attributes and an indication of an initiator of a potential second rate change to the machine learning model to predict client sensitivity to the potential second rate change. Then, a recommendation is provided as to whether to change the second rate based on the predicted client sensitivity.

Abstract: A lock box including a main body, a lid, an electronic locking mechanism, a lid sensor, and a processing circuit. The main body defines a compartment. The main body is structured to be secured within or secured to a substantially permanent structure. The lid is positioned to selectively enclose the compartment. The electronic locking mechanism is positioned to selectively lock the lid to the main body. The lid sensor is configured to detect at least one of an attempt to open the lid or opening of the lid. The processing circuit is configured to generate an alert in response to the lid sensor detecting the at least one of the attempt to open the lid or the opening of the lid.

Abstract: A system includes a remote server and a device having a wireless transceiver, microphone, and processing circuit. The processing circuit is configured to monitor the microphone for a siren signature. The processing circuit is configured to use the wireless transceiver to send information to the remote server in response to a detection of the siren signature. The remote server causes wireless cameras located near the device to capture a current image and to send the captured image to the remote server for further distribution.

Abstract: A method of communicating between a wireless security device and a security server through an access point includes estimating a link latency between a time of transmission of a message from the wireless security device and a time at which a response is received from the security server. A polling mode is enabled in which the access point will hold messages received by the access point that are directed to the wireless security device while the device is in a sleep state, without discarding the messages for a threshold period of time. The wireless security device may be placed in a sleep state and woken after a wake time determined based on the estimated link latency, and receives any messages received by the access point during the sleep state.

Abstract: A method of securing communications between a security device and a security server include receiving, at the security server, a registration request from the security device, the registration request being encrypted using an initial registration key. A device identifier and rotation key unique to the security device are transmitted to the security device. A first session key request is received at the security server from the security device, the request being encrypted using the rotation key. A first session key is transmitted to the security device in response. One or more communications, encrypted using the first session key, is received at the security server from the security device. A second session key request is received at the security server from the security device after the first session key has expired, the request encrypted using the rotation key. A second session key is transmitted to the security device in response.

Abstract: A gutter assembly (1) including a longitudinally extending channel (5) having an opening (10) and downwardly converging side surfaces (15) terminating at a bottom surface (20) to receive and disperse therealong water runoff from a roof (25) of a building (30). At the opening (10) the side surfaces (15) have a longitudinal edge portion (35) remote from the building (30) and a longitudinal edge portion (40) adjacent the building. Fastening means (50) secure the assembly (1) to the building. The side surfaces (15) are angularly offset relative to each other so that in use the center of gravity of the assembly (1) is adjacent the building (30) to thereby urge the assembly (1) towards the building when the assembly (1) is under load.

Abstract: For a push-to-talk arrangement in a dispatch call communication system (100), an originator (10) selects a group of called parties (11-14). A push-to-talk server (50) handles a dispatch call in a conventional manner. If all the called parties (11-14) do not respond, the originator is given an option to leave a message for an unavailable party (116). A multimedia message service server (60) is the storage medium for these messages. Any unavailable called subscribers (11-14) are provided an indication of a waiting message (128).

Abstract: A method of determining PTT availability of members of a contact list in a wireless PTT communication system makes efficient use of resources by updating client devices (118, 122, 126) with new PTT contact list status information only when necessary. The availability of client devices (118, 122, 126) associated with contact lists (528, 530, 532) are determined by a PTT controller (112) according to the content of messages from the client devices (118, 122, 126). New information regarding the availability of a client device associated with a contact list (528, 530, 532) is transmitted to relevant client devices (118, 122, 126) only when a change has occurred in the availability of a member. Likewise, a client device (118, 122, 126) notifies the PTT controller 112 of its availability only when a change occurs.
