摘要： Provided herein is a system and method for determining the status of one or more wireless communication links in a network such as a personal area network. One or more nodes within the PAN substantially continuously monitor a plurality of quality of service (QoS) communication indicators and generate a first application link quality indicator (ALQI) based on a first subset of the plurality of QoS communication indicators according to a first time period. The node can then modify the first ALQI with a second subset of the plurality of QoS communication indicators only when a first predetermined threshold number of occurrences of the second subset of the plurality of QoS communication indicators has occurred without regard to the first time period to form a first modified ALQI. The node can then report the modified ALQI to a coordinator node that can then act upon the modified ALQI to possibly correct one or more communication link problems to which the reported ALQI pertains to.

摘要： A method that detects obstacles on a roller shade's travel that create excess torque by sensing the current draw from a motor and method by which the motor can calibrate itself to detect excess torque. During the roller shade's travel, it will record the instantaneous torque being generated at various points. For example, it will store the greatest value in the shade motor's non-volatile memory as the normal operating torque.

摘要： A building management system is disclosed that is automatically configured using a wireless mesh network data and sensor data to create a virtual floor plan. The building management system comprising a control processor, a plurality of lighting devices, and a plurality of control devices comprising lighting control devices, each directly controlling one or more of the lighting devices. The control devices intercommunicate with each other over a wireless network, and each control device comprises a light sensor detecting light intensity. The control processor creates the mesh graph of relative positioning of the control devices to each other using received wireless signal strengths of the control devices relative to each other. The control processor determines relative positioning of the lighting devices to the control devices using the mesh graph and received light intensity readings obtained by the light sensors of the control devices when each lighting device was turned on and off. The virtual floor plan comprises the relative positioning of the control devices to each other, the relative positioning of the control devices to the lighting devices, and room-by-room groupings of the plurality of control devices and the lighting devices.

摘要： When switching sources, resolutions or refresh rates in a video distribution network, switching times are reduced by maintaining video lock and security authentication between a video switcher and a video sink. The scaler maintains video lock and security authentication by continuing to generate video timing data during switching events. The scaler also facilitates an aesthetically pleasing transition by generating image content data prior to and after the switching event.

摘要： A multi-channel Class D audio amplifier is provided to substantially reduce channel-to-channel crosstalk by employing in each channel a local triangle ramp generator controlled by a single global digital timing signal. The noise critical timing/integrating capacitor for the triangle ramp generator resides locally in each channel and adjacent to the PWM comparator of that channel and referenced to the local ground of that channel. The amplifier can also include a duty cycle limitation circuit to limit output power availability depending on the impedance of any attached loads (speakers).

摘要： Presented is a method for controlling a roller shade having a roller tube windingly receiving a flexible shade material. The method includes providing a motor that rotates the roller tube to move the flexible shade material between a first position and a second position. The method further includes capturing, with an optical sensor, an image frame at a plurality of linear positions along the flexible shade material as the flexible shade material moves from the first position to the second position. The method further includes controlling the reversible motor to move the flexible shade material from the first position to the second position in response to position information obtained from the captured image frames using a variable linear velocity profile so that the flexible shade material moves from the first position to the second position at a variable linear velocity.
