Abstract: A method includes operating, by a device, a microphone incorporated in the device in a half-duplex mode; receiving, by the device, a message to initiate a session with another device, the message including a parameter; parsing, by the device, the message to identify a mode of operation of the microphone based on the parameter; and adjusting, by the device, the microphone to operate in a full-duplex mode based on identification of the mode of operation.

Abstract: A device including a speaker and a housing, in which the speaker is configured to generate sound and includes a diaphragm and the housing encloses the speaker and includes a plurality of openings within one portion of the housing. The speaker is positioned within the housing to define a front chamber between the diaphragm and the one portion, and the plurality of openings are sized to collectively generate, with the front chamber, an increased output of the device within a frequency range of an output of the speaker corresponding to an alarm tone. Also provided are methods for assembling a device including a speaker and a housing.

Abstract: An illuminated indicator for a doorbell can be arranged to receive light along an optical axis (e.g., that is perpendicular to a front face of the doorbell housing) and emit the light from an output portion that defines a closed loop (e.g., that extends around the optical axis) and in a direction that is parallel to the optical axis. The illuminated indicator can include a light pipe that receives light along the optical axis and reflects the light to follow a radially outward and divergent path, e.g., that is perpendicular to the optical axis. The radially outward and divergent light can be reflected to follow a path that is parallel to the optical axis for emission at an output portion of the light pipe. The light pipe can be configured to transmit a doorbell switch activation force to other parts of the doorbell to cause actuation of the switch.

Abstract: One disclosed method involves receiving a first request to establish a first connection between a computing device and a camera, wherein the first connection is configured to allow streaming of video data from the camera to the computing device and the camera is configured to support connections with multiple remote devices at one time. A determination is made that a second connection is already established between an endpoint device and the camera, wherein the second connection is configured to allow streaming of video data from the camera to the endpoint device. Based at least in part on the first request and the second connection already being established, the second connection is terminated and the first connection is established, thus providing the computing device with access to one or more functionalities of the camera free of interference by the endpoint device.

Abstract: In one example, a device includes an image sensor and a light source positioned relative to the image sensor so that light from the light source is reflected away from the image sensor by first objects that are within a field of view of the image sensor, the first objects being positioned less than a selected distance from the image sensor. In an example, the device further includes at least one processor and a data storage device storing instructions that when executed by the at least one processor cause the device to acquire, with the image sensor, at least one image of a scene based on reflections of the light from the light source, the at least one image depicting a second object but not the first objects, the second object being positioned further from the image sensor than the selected distance.

Abstract: A doorbell including a housing and mount that can be engaged such that the housing is pivotable or otherwise movable relative to the mount for engagement with the mount and/or for activation of a doorbell switch. A latch can secure the housing to the mount so the housing is secured to the mount. A switch located in a space defined by the housing and mount can be actuated based on movement of the housing relative to the mount.

Abstract: Motion detectors can include a housing defining a first cavity and an aperture extending through the housing. A circuit board can be disposed in the first cavity. An infrared sensor and a light sensor can be mounted on the circuit board. A lens can extend across the aperture. A wall can extend between the lens and the circuit board such that the wall, the lens, and the circuit board define a second cavity at least partially within the first cavity and the second cavity contains the infrared sensor and the light sensor.

Abstract: A location monitoring system, such as an alarm system employed at a house or other location, can include a wireless, battery-operated camera. The camera can have a low power mode in which all components other than a low power communications module are deactivated. The camera can be activated by a signal received by the low power communications module, and the camera can establish a direct communications link with, and send video image data to, a remote server. Where the camera/server direct communications link is inoperable, a link to a local controller is established, and at least a portion of the video image data sent to the controller, which can send a portion of the video image data via an alternate network.

Abstract: A method is provided. The method includes causing, by a controller of a device, at least one processor of the device distinct from the controller to power on in response to receipt of a signal from a sensor of the device configured to detect motion within a field of view; analyzing, by the at least one processor, one or more images from an image sensor of the device to identify an image of a person; sending, by the at least one processor, a trigger to a base station in response to identification of the image of the person; and booting, by the at least one processor, a multitasking operating system of the device after sending the trigger to the base station.

Abstract: A smoke detector includes detector mount that can define a cavity into which air can flow to a detector component of a detector body engaged with the detector mount. The detector mount can include a base, e.g., that defines a cavity into which air can flow and/or into which a portion of the detector body can extend, and an intermediate component that can removably engage with both the base and the detector body so the base is engaged with the detector body via the intermediate component. The intermediate component can include fins or other features to direct air flow in the cavity to one or more portions of the detector body.

Abstract: In one example, a method of motion detection includes producing a first image based on a plurality of previous images, the first image including pixels having intensity values that approximate a difference in intensity values between a pair of pixels within the previous images, and the pair of pixels being one pixel from each of first and second previous images and present at the same locations within their respective images, generating a second image by applying a threshold to the first image, the second image including one or more pixels with intensity values above the threshold, the threshold being derived from intensity values of pixels within the first image and a number of pixels in the first image with a respective intensity value, and determining a region of the second image indicating motion based on a location of the one or more pixels in the second image.

Abstract: In accordance with one disclosed method, a computing system may cause a first computing device to display a first notification of a first event detected at a monitored location, and may cause a second computing device to display a second notification of a second event detected at the monitored location. The computing system may additionally cause the second computing device to cease display of the second notification in response to a change of status of the first event.

Abstract: Systems and methods for controlling a speaker. In one example, a method includes determining, based on a request to operate a speaker, a type of sound to be produced by the speaker, the request being indicative of whether operation of the speaker is for a communication session or to produce a system sound, and adjusting one or more parameters of the speaker to output (i) speech, based on the request indicating that operation of the speaker is to be for the communication session, or (ii) the system sound, based on the request indicating that the operation of the speaker is to produce the system sound. An example of the method further includes initiating operation of the speaker using the one or more parameters to produce the type of sound.
