Abstract: Methods and devices may be used to remotely hushing alarms by receiving an indication of an alarm event occurring at a remote device and presenting a visual indicator of the alarm event including a hush option to alter an audible and/or visual alarm notification of the remote device. A user selection of the hush option is received. In response to receiving the user selection of the hush option, communicating, from the electronic device to the remote device via a point-to-point low power wireless connection between the electronic device and the remote device, a hush request requests that the remote device alter its audible and/or visual alarm notification and causes an adjustment of the visual indicator to reflect a status of the hush request.

Abstract: Systems and methods for activating select devices are described herein. More particularly, this specification relates to using structure specific service IDs (SSSIDs) when two devices that are part of a common ecosystem are deciding whether to establish a connection according to a Bluetooth protocol. The SSSID can be a unique identifier that can be included in packets that are transmitted in accordance with the standards defining the Bluetooth Low Energy (BLE) protocol. The SSSIDs can be generated and provided to select devices such that only the select devices that are in possession of the SSSID are able to communicate with each other. This advantageously eliminates spurious activation of unintended recipient devices by enabling them to ignore the packet if the SSSID is not recognized, thereby enabling the unintended recipient device to remain in a low power sleepy state.

Abstract: A computing system receives blackbody radiation data from a thermal radiation sensor that is located in a room with a heat source and is directed at the heat source. An operating state of the heat source is determined using the blackbody radiation data. Occupancy data is received for a dwelling that includes the room with the heat source; using this data, an occupancy of the dwelling is determined, including an occupancy for the room. It is determined, using the operating state of the heat source and the occupancy of the dwelling, including the occupancy of the room, whether a heat-source alert condition that includes a first threshold time is met. If so, a heat-source alert is provided. A request of a first type is then received to cancel the heat-source alert. In response, the heat-source alert is canceled and the heat-source alert condition is modified.

Abstract: Systems and methods for reducing connection latency are described herein. More particularly, this specification relates to shortening connection latency between devices operating according to a Bluetooth protocol. Connection latency can be reduced by using the receipt of a wireless packet as a trigger for selectively accelerating a transmission rate of advertising packets. By selectively accelerating the transmission rate advertising packets, a connection interval between two devices can be shortened.

In an embodiment, a method includes reading, by a processor, tile data of a database in a specific order, wherein the tile data comprises one or more reference data points and/or one or more empty spaces. The method also includes compressing, by the processor, the tile data based on the specific order using encoding. And the method further includes generating relative positions for each individual reference data point with respect to each other in the compressed tile data without specific location identification information for each reference data point.

Abstract: An embedded system and an interruption handling method are provided. A plurality of interruption requests are received, and corresponding service routines are triggered with priority control. In the embedded system, a memory device comprises a plurality of service routines stored at different entry addresses, each related to an interruption request. A processor receives an enable signal to initialize one of the service routines through a branch instruction. A control unit buffers the interruption requests to schedule executions of corresponding service routines. When a specific service routine is to be executed, the control unit provides the branch instruction pointing to entry address of the specific service routine and asserts the enable signal to the processor, such that the processor executes the branch instruction to initialize the specific service routine.

Abstract: An electronic system includes a host; a controller electrically coupled to the host through a single port of a predetermined bus, the single port for providing the host access to N devices; and M peripheral devices electrically coupled to the controller, M being greater than N.By modifying control codes, reserved vendor-specific bits in packets or registers in an IDE task file that are sent between the host and the controller, the host is able to specify a target peripheral device and to determine which peripheral device sent each packet that is received by the host. In this way, the host can access the peripheral devices using the single port. When the peripheral devices include a first peripheral device and a second peripheral device, the controller can directly transfer data stored on the first peripheral to the second peripheral device without requiring the data to be buffered in the host.
