摘要:
An alarm system can provide security, fire, protection, or other alarm services for a premises, such as for a building or other property. When the alarm system detects an alarm condition, such as an intrusion or a fire, a two-way voice channel can be opened between the premises and a remote entity. Via the two-way voice channel, an operator at a central monitoring station can verbally communicate with someone at the premises, for example. A person associated with the alarm system may own a mobile communication device, such as a smartphone or other handheld cellular device. If the mobile communication device located is at the premises, the two-way voice channel can be established between the remote entity and the mobile communication device. Location of the mobile communication device can be determined based on GPS, service provider tracking, or user entry, for example.

A system and method of wirelessly communicating in a backplane mesh network is disclosed. A data message received from a first network device is handled at a first antenna system located in a first network device cabinet via a first network interface. The data message is wirelessly transmitted from a first millimeter wave antenna coupled to the first antenna system over a high speed backplane network to a second network device in a second device cabinet using emitted millimeter wave electromagnetic radiation. The data message is wirelessly received at a second millimeter wave antenna over the high speed backplane network using emitted millimeter wave electromagnetic radiation, wherein the received data message is handled by a second antenna system coupled to the second millimeter wave antenna. The received data message is sent, via a second network interface, from the second antenna system to the second network device.
摘要:
Delivery of alarm system event data and audio. In certain aspects, a method for delivery of alarm system event data is described, including communicating alarm event data from an alarm system to a private telecommunications switch. In turn, the alarm event data may be communicated to a message processing gateway. The message processing gateway evaluates service parameters of the alarm system and, in certain cases, instructs the private telecommunications switch to contact a central alarm monitoring station if certain service parameters are met. In additional aspects, private telecommunications switch opens a voice channel between the private telecommunications switch and the central alarm monitoring station and communicates the alarm event data. Additionally, in response to a determination that a voice channel between the private telecommunications switch and the central alarm monitoring station remains open, the private telecommunications switch may also bridge the voice channel to the alarm system.

Delivery of alarm system event data and audio over hybrid networks is described. In one embodiment, delivering alarm system event data includes detecting an alarm event and communicating alarm event data to a message processing gateway, evaluating service parameters of the alarm system and conditions of the alarm event data, forwarding the alarm event data and a voice channel code to a telecommunications switch, and opening a voice channel between the telecommunications switch and a central alarm monitoring station. In other aspects, delivering alarm system event data and connecting a voice channel further includes determining whether the voice channel remains open, forwarding a routing code to the alarm system, opening a voice channel between the alarm system and the telecommunications switch, and bridging the voice channel between the telecommunications switch and the central alarm monitoring station and the voice channel between the alarm system and the telecommunications switch.
摘要:
An interface for interactive control of alarm systems using an intermediate gateway. A request for access to an account for interactive alarm system control is received from a remote device by an intermediate gateway. The request for access from the remote device is authenticated by the intermediate gateway based on an authentication parameter. After authenticating, the intermediate gateway identifies an alarm system and attributes of the alarm system associated with the request for access. Here, for example, the intermediate gateway identifies the operating characteristics for remote access to the alarm system. Further, the interactive gateway may receive a prompt from the remote device. Based on the prompt, the intermediate gateway may communicate with the alarm system according to its identified attributes and in response to the prompt, to query or update at least one setting of the alarm system.

摘要:
A pitch control system for a wind turbine is disclosed. The pitch control system may generally include a motor having an armature and a winding and a grid power source configured to supply electrical power to the motor. The pitch control system may also include a plurality of switching components configured to control a first current through the armature independent of a second current through the winding. In addition, the pitch control system may include an auxiliary switching component electrically coupled between the grid power source and at least a portion of the switching components. The auxiliary switching component may be configured to be opened when a grid voltage of the grid power source exceeds a first voltage threshold.

A plurality of users may interact with a content distribution system in order to share digital media content. The system may receive, store, and/or publish a delivery specification that includes requirements relating to digital content that a first user wishes to receive. The delivery specification for the digital content may include one or more requirements of the digital content to be received. A second user who wishes to provide the digital content may access the delivery specification. The system provides for flexible validation of the media content from the second user. For example, validation may occur at device of the first user, at a device of the second user, and/or at a device of the content distribution system. Upon validation of the media content from the second user, the system may facilitate transfer of the media content from the second user to the first user.

The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.
