Abstract: Alignment between closed caption and audio/video content may be improved by determining text associated with a portion of the audio or a portion of the video and comparing the determined text to a portion of closed caption text. Based on the comparison, a delay may be determined and the audio/video content may be buffered based on the determined delay.

Abstract: Methods and apparatus for detecting false alarms are disclosed. An indication may be received that a sensor device has changed state. Data indicative of movement of the sensor device may also be received. Based on the received data indicative of movement of the sensor device, it may be determined whether the movement of the sensor device is abnormal. Based on the changed state of the sensor device and based on determining that the movement of the sensor device is abnormal, an indication of a false alarm may be caused to be output.

Abstract: A system for storing and moving data based on the location of a user or a change in location of a user is described herein. Data associated with a user may be stored at one or more storage devices associated with a location of the user. Some or all of the data associated with the user may be moved to one or more other storage devices if, for example, the user moves to a different location or is expected to move to a different location, so that the user's data may be more efficiently accessed by the user.

Abstract: A device (e.g., a security device, a video doorbell, a security camera, etc.) may receive an input voltage and based on the input voltage may determine the input power available to the device. The device may access various power level requirements associated with one or more functional components associated with the device. The device may then determine one or more functional components to activate or set to an active status on the device based on the input power available to the device, component power level requirements for one or more of the functional components, and other factors such as priority levels and preferences.

Abstract: Systems, apparatuses, and methods are described for using one or more components of a device, such as a camera, to generate complementary heat for the device, such as a camera lens of the device. In one aspect this can be accomplished by activating the one or more components and/or by causing the one or more components to operate in a particular manner expected to generate heat. The generated heat may be instead of or in addition to heat generated by one or more dedicated heaters. The selected components may produce heat as an incidental effect for performing other functions of the device.

Abstract: Premises management systems may comprise one or more pressure sensors and one or more pressure plates. A pressure sensor may be located on a first sash of a window at a premises. A pressure plate may be coupled to the pressure sensor and may be located between the first sash of the window and a second sash of the window. A position of the pressure plate relative to the pressure sensor and/or between the first sash and the second sash may be adjustable.

Abstract: Methods and systems are disclosed configured to perform automated volume leveling on speech content in an audio file containing speech and non-speech segments. A low pass filter and a high pass filter may be applied to the audio data, and normalization may be performed. Speech and non-speech segments may be detected. Gain adjustments may be made to achieve a substantially constant short term loudness. Processing may be applied to enhance speech parameters, such as attack and release. An upward expander may be used to achieve a target loudness level. A limited and/or dynamic range compressor may be utilized to satisfy true peak and/or short term loudness specifications. A file of processed audio data may be generated and transmitted to one or more destinations for broadcast and/or streaming.

Abstract: Systems, devices, and methods are described for reducing degradation of a voice recognition input. An always listening device may always be listening for voice commands via a microphone and may experience interference from unwanted audio such as from the output audio of television speakers. The always listening device may receive data associated with the output audio over a first communications channel. The always listening device may also receive, on a second communications channel, timing information associated with data. The always listening device may adjust admission of the audio received by the microphone to enable it to arrive at approximately the same time as the data received via the first communications channel. The unwanted output audio included in the audio received via the microphone may then be determined and may be removed so that a voice command in the audio received by the microphone may be processed.

Abstract: Data (e.g., images, video, data fields, character strings, logos, etc.) may be analyzed to identify common elements and differentiating elements, and the elements may be respectively transmitted using different streams. For example, if two devices are receiving two video images that are nearly the same, a first data stream comprising the one or more identified common elements may be sent to them both, a second data stream comprising a portion of the one or more identified differentiating elements may be transmitted to the first device, and a third data stream comprising a different portion of the one or more identified differentiating elements may be transmitted to the second device.

Abstract: One or more computing devices may be configured to identify information corresponding to a program change request associated with a multi-program data transmission. The information may comprise at least a link to a desired program within the multi-program data transmission. The one or more computing devices may communicate the link to the desired program to a client device over a specified time period. After the time period, the one or more computing devices may communicate the desired program to the client device using a single program data transmission. The single program data transmission may be derived from the multi-program data transmission.

Abstract: Systems, apparatuses, and methods are described for managing temperature of a rechargeable battery between multiple available states of heating. Different thresholds may be used for turning on, and turning off, one or more heating elements associated with the rechargeable battery, and/or for otherwise changing states of the one or more heating elements.

Abstract: A camera device's exposure to sunlight may be monitored. The sun exposure may be used to predict a solar event associated with the camera device, such as a critical temperature, a brightness level, or an angle of sunlight. Prior to occurrence of the solar event, one or more functions of the camera device may be enabled or disabled. For example, a cooling function of the camera device may be enabled or a characteristic of video streamed by the camera device may be modified. The function may be re-enabled or re-disabled after the solar event.

Abstract: Systems, methods, and apparatuses for power management of doorbell systems are described herein. A doorbell system comprising at least a camera and a chime may cause a connection to be established. The connection may be established between the camera at least one user device. A first indication to cause the chime to output a first audio notification may be received. Based on determining that the connection is established between the camera and the at least one user device, prevention of outputting the first audio notification by the chime may be caused.
