An intelligent door lock system is coupled to a door at a dwelling. A first sensor is at the dwelling. The first sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. The lock device is coupled to the first sensor and the lock device includes a bolt. An engine, an energy source and a memory are coupled together. A magnetic sensor provides a reading or measurement used to determine a door open or closed status.

Door lock system with contact sensor

A security system is coupled to a door lock system at a dwelling. A lock device is provided with a lock and a drive shaft. An intelligent door lock system includes: a door status device configured to couple to the drive shaft of the lock device, the door status device determining lock or unlock status of a the lock device, an engine that provides power to lock and unlock the lock and coupled to the door status device, the engine coupled to at least one wireless communication device at the dwelling configured to with a mobile device of a dwelling occupant for communication with the intelligent door lock system to lock or unlock the door, a circuit coupled to the engine, and an energy source coupled to the circuit and providing power to lock or unlock the door, wherein an occupant/owner, or end-user of the dwelling communicates with a server to grant third party access to the dwelling. A security system is configured to be coupled to the intelligent door lock system. The security system includes a video apparatus that captures video is coupled to a motion detection device to take a video of an image of the person or an outline of the person. The video apparatus is configured to provide communication with a communication device of the third party. In response to a communication with the video apparatus and the communication device of the third party, the third party is granted controlled access to the dwelling.

Security system coupled to a door lock system

A security system is coupled to a door lock system. A sensor is at a dwelling. The sensor is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at a door. An engine, an energy source and a memory are coupled together. The engine is coupled to the sensor. The memory provides information relating to open or closed status of a door to a dwelling occupant or a third party designated by the dwelling occupant. At least one motion detection device is provided to detect a person at or near a door or window at the dwelling. A security system includes a video apparatus that captures video and coupled to the motion detection device to take a video of an image of the person or an outline of the person, wherein the video is configured to begin before motion detection begins.

An audio encoder configured to encode an audio signal to generate a bitstream having E-AC-3 format, including by determining a first control parameter indicative of an allocation of available mantissa bits for quantized audio content of the signal. The encoder is configured to perform transcoding simulation to determine a second control parameter in a manner based at least in part on statistical analysis of results of E-AC-3 bit allocation processing of audio data assuming a first target data rate, and of AC-3 bit allocation processing of the data assuming a second target data rate, and to include the second control parameter in the bitstream for use by a converter to convert the bitstream into a second bitstream having AC-3 format at the second target data rate. Other aspects are converters configured to perform transcoding on a bitstream using such a second control parameter, and methods performed by any embodiment of the inventive encoder or converter.
