Abstract: A system and method for determining a false alarm includes receiving a provisional alarm signal from a safety alarm system, the provisional alarm signal indicating an alarm type. At least one sensor senses at least one present condition of a type corresponding to the alarm type indicated by the provisional alarm signal. A normal alarm signal is transmitted based on the at least one present condition sensed by the sensor.

Abstract: An audio/video (A/V) hub that coordinates playback of audio content is described. In particular, the A/V hub may calculate current time offsets between clocks in electronic devices and a clock in the A/V hub based on differences between receive times when frames are received from electronic devices and expected transmit times of the frames. For example, the expected transmit times may be based on coordination of clocks in the electronic devices and a clock in the A/V hub at a previous time and a predefined transmit schedule of the frames. Then, the A/V hub may transmit, to the electronic devices, one or more frames that include audio content and playback timing information, which may specify playback times when the electronic devices are to playback the audio content based on the current time offsets.

Abstract: An electronic device that coordinates a playback operation is described. In particular, an interface circuit in the electronic device may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may determine a remaining time offset between the clock and the second clock. Next, the interface circuit may modify a future time when the electronic device is to perform the playback operation based on the remaining time offset to determine a corrected future time, and the electronic device may perform the playback operation at the corrected future time.

Abstract: An audio/video (A/V) hub that determines an environment of a portable electronic device is described. In particular, the A/V hub may identify the environment based on performance information about communication between the portable electronic device and receiver devices (which was received from the receiver devices), and a history of behavior of an individual associated with the portable electronic device and the A/V hub. Alternatively, the A/V hub may identify the environment based on performance information about communication between the portable electronic device and the A/V hub and the portable electronic device and another A/V hub (which was received from the portable electronic device and/or the other A/V hub), and a history of behavior of an individual associated with the portable electronic device and the A/V hub. Based on the determination, the A/V hub provides an instruction to power on an A/V display device in the environment.

The leveling pad comprises a metal base having a socket configured to receive a portion of the device and a liner coupled to the metal base and being configured to cold flow into a profile of a floor surface when a weight of the device is applied to the leveling pad. The liner may be of a polymer, such as vinyl. The liner is further configured to plastically deform into the profile of the floor surface. The plastic deformation is designed to increase a magnitude of a shear force or a tensile force required to separate the liner from a portion of the floor surface into which it is configured to plastically deform.

Abstract: An electronic device that reduces relative drift is described. In particular, an interface circuit in the electronic device may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may store the adjustments to the clock circuit. Furthermore, when a wireless reset occurs, the interface circuit may adapt the clock circuit based on the stored adjustments to reduce the relative drift while the interface circuit restores frequency lock with the second clock based on additional packets with additional transmit times that are received from the second electronic device.

Abstract: An audio/video (A/V) hub may measure the sound, corresponding to audio content, output by electronic devices. Then, the A/V hub may compare the measured sound to a desired acoustic characteristic at a first location in the environment based on the first location, a second location of the A/V hub, and an acoustic transfer function of the environment in at least a band of frequencies. For example, the comparison may involve calculating the acoustic transfer function at the first location based on the acoustic transfer function at other locations in the environment and correcting the measured sound based on the calculated the acoustic transfer function at the first location. Moreover, the A/V hub may determine equalized audio content based on the comparison and the audio content.

Abstract: A portable electronic device with a touch-sensitive display (such as a cellular telephone) provides a wireless remote control for an entertainment device (such as a consumer-electronic device). Based on device-state information that specifies a current state of the entertainment device (which is received from an audio/video (A/V) hub that communicates with the entertainment device) and one or more related states of the entertainment device, the portable electronic device may generate a user interface that includes one or more virtual command icons. Note that the one or more related states are related to the current state in a state diagram by corresponding operations that transition the entertainment device from the current state to the one or more related states. Then, the portable electronic displays the user interface on the touch-sensitive display. In this way, the portable electronic device dynamically adapts the user interface.

Abstract: A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly.

Abstract: A transport system comprising linear motor modules utilized both straight and curved track modules, with movers displaced on the track modules by control of power applied to coils of the modules. Curved track modules have modified spline geometries to provide desired acceleration and jerk characteristics. The modified spline geometries may be defined by more than one generators, such as an equation generator and a spline fit between the equation-generated segment and one or more constrained points or locations. The curved track modules may be divided into 180 degree modules, or may be reduced to 90 degree, 45 degree or other fractional arcs to provide for modular assembly, mirror-image geometries and motion profiles, and the like. The system may be adapted to provide improved motion characteristics based on modification of a conventional spline geometry.

Abstract: In order to maintain performance during wireless communication, a transmitting electronic device may concurrently and independently communicate redundant information to a receiving electronic device. In particular, information associated with a data stream may be communicated to the receiving electronic device using one or more channels by two radios using one or more wireless local area network communication protocols. The packets transmitted by the radios may preferentially include the same information. Moreover, the transmitting electronic device may attempt to maintain the redundant communication if a performance metric associated with the one or more channels degrades. For example, the transmitting electronic device may transfer communication to a different channel or may compress the information in the packets in the one or more channels if the throughput drops below a threshold value.

Abstract: The patent describes the embodiment of system and methods of a modular IOT enabled router with user controllable and pluggable modules. The architecture of the router and plugins allow users to install packet level and application level modules at real-time without affecting the latency and router performance. The installed modules are executed in parallel in their own executing unit and in the predefined or user-specified order. The leveled architecture allows fine-grain control of the routing and forwarding internals like QOS, deep packet inspection, encryption, traffic flow control, and traffic filtering via packet level modules. At the same time, it allows running service like a proxy, firewall, web acceleration, ad-blocking via application level modules. The full control provides an easy interface for a developer to write plugins for new protocols, SDN, IOT, and user applications and run them in separate controlled execution engine without affecting the core router engine that is running security.

Abstract: A collaborative robot employs low ratio drives for three or more axes of movement, such as three primary axes. An arm assembly may be mounted to a support for movement along a vertical linear axis, and the arm assembly may include first and second arm links that are each rotatable about vertical axes, e.g., such that the arm links move in a horizontal plane. Low ratio drives may be used for movement along the vertical linear axis and the rotary axes for the first and second arm links. Feedforward and feedback control may be employed to control the movement of the arm assembly and arm links, and feedback torque components may be limited to 25% or less of the maximum drive torque.
