Abstract: In implementations described herein, A/V recording and communication doorbell devices (“A/V doorbells”) and signaling devices may be powered from a common AC waveform. In some implementations, an A/V doorbell and its corresponding signaling device may be arranged in a circuit loop where a portion of an AC waveform is used to power the A/V doorbell and the other portions of the AC waveform is used to power the signaling device. For example, a positive phase of the AC waveform may be used to power one of the A/V doorbell or signaling device and a negative phase of the AC waveform may be used to power the other of the A/V doorbell or signaling device. In some cases, an energy harvester device may be used to slow charge a battery or supercapacitor from the circuit loop to power the A/V doorbell and/or signaling device.

Abstract: A vocoder system incorporates situational awareness data into unused bits in the trailing bytes of the vocoder frames by dividing the situational awareness data according to the number of known blank bits in each vocoder frame and incorporating the data, in order, such that the receiving system can extract and reconstruct the situational awareness data. Synchronization signals of predefined bit streams are incorporated to allow the receiving system to more accurately identify situational awareness bits in the trailing byte.

Abstract: A communications node of a multi-node communications network is disclosed. In embodiments, the communications node includes a communications interface and controller. The controller transitions the clustering status of the communications node to a clusterhead node status. The clusterhead node identifies a cluster of neighboring nodes with which it is in communication by transmitting hello messages identifying the clusterhead node and its status but omitting a one-hop neighbor list. The clusterhead node refines link discovery to the nodes of the multi-node communications network by flooding the network (e.g., via its cluster of neighboring nodes) with routing status messages, which network nodes not part of the dominating set of clusterhead nodes are restricted from sending.

Abstract: A Lawn mower Diverter/Bee Guard or accessory warning device for diverting and saving honeybees and other endangered insects. The device components include a plate for removably securing the warning device to the mower deck; a manner for removably connecting and securing the plate to the deck; a warning emitter; and a way for securing a warning emitter to the plate. Alternative mechanical designs and light, sound, electro-magnetic force, and spray devices are shown as other embodiments. The warning device alerts the pollinating bees of the oncoming mower so the bees can survive by flying away and averting their demise by the mower. Alternative devices for warning are sound, light, smoke, spray, and Electro Magnetic force/pulse generators placed with the mowers.

In various implementations, the supercapacitor control circuitry may control the amount of current supplied from the one or more supercapacitors to one or more functional components of the A/V doorbells.

Abstract: A large scale hierarchical and heterogeneous network, and specifically mobile ad-hoc networks (MANETs), derive content elements from a plurality of informational data points via spectrum fusion at each hierarchical level. Content elements may be derived via fusion of information data from peer nodes and from content elements from lower hierarchical levels. Content elements are propagated up for further abstraction at higher hierarchical levels. Each content element is tagged with a node location and external reference direction. The node location and external reference direction facilitate fusion are each hierarchical level where the deriving node is receiving content elements from a plurality of different nodes.

Abstract: An audio/video (A/V) recording and communication doorbell device includes an input port, a switch, a first power supply, a second power supply, a button, a first controller, and a second controller. The switch is electrically coupled across the input port. The first power supply receives power from the input port and powers a first power supply rail, and the second power supply powers a second power supply rail. The button, when pressed, activates a signaling device. The first controller is at least partially powered from the first power supply rail and closes the switch in response to the button being pressed. The second controller is at least partially powered from the second power supply rail.

Abstract: An apparatus for measuring movement characteristics of a first hair switch includes a movement rig, a camera, and a computer. The first hair switch is mountable on the movement rig. The movement rig is operable to apply a forced oscillation to the first hair switch. The camera is for capturing images of the first hair switch during movement of the first hair switch during and after application of the forced oscillation. The computer is communicably connected to the camera. The computer includes a processor for processing the images and extracting quantitative measurements of the first hair switch from the images. A filter is applied to the images to remove any stray hairs detected before subsequent analysis of the images is carried out.

Abstract: This disclosure describes techniques for using alternating current (AC) power waveforms to communicate between devices in a doorbell circuit. A signaling device that emits sound may be positioned in the doorbell circuit between an AC power source and a doorbell device (such as an A/V device including a doorbell). A signaling device may be coupled in parallel to a signaling-control device that includes electronic circuitry that provides a selective bypass to allow for larger amounts of current drawn by the A/V device to bypass the signaling device without causing the signaling device to emit the sound. The A/V device and the signaling-control device may use AC power waveforms to communicate data and/or data between each other. For example, the A/V device and the signaling-control device may control respective signal relays to selectively open and close the doorbell circuit in order to communicate with each other using the AC current waveform.

The system propagates spectrum sensing information upward, and propagates rule sets, policies and configuration parameters downward in order to create autonomous DSA decisions.

Abstract: In implementations described herein, power is supplied to functional components of audio/video (A/V) recording and communication doorbell devices (“A/V doorbells”) during activation of signaling devices that are coupled to the A/V doorbells without the use of a backup power supply.

The first parallel circuitry and the second parallel circuitry are configured to supply sufficient power to the functional components of the A/V doorbell during activation of the signaling device. In particular implementations, the first parallel circuitry and the second parallel circuitry include shunting circuitry to control the flow of current through the first and second parallel circuitry and supply sufficient power to both the signaling device and the A/V doorbell.
