Abstract: This disclosure relates in general to a networked light switch. More specifically, the disclosure relates to a light switch that, in response to detecting a local input or motion, transmits a communication that causes another light switch to change a state of a light. This disclosure further relates to techniques for detecting an abnormal current draw state of an electrical device such as a lighting device are described; systems including in-wall network devices having a user-facing restore button for restoring some or all of the customizable settings to a factory default state; and techniques for controlling device operations in accordance with scenes or modes.

Abstract: Techniques can relate to a multi-purpose a detector surface on a network device. A stimulus variable can be identified at a detector device based on an environmental stimulus detected by a sensor. The detector device can include the sensor. The detector device can transmit an initial communication to a device. The first communication can include the stimulus variable. A new communication that includes data corresponding to another device can be received at the detector device. The detector device can determine, based on the stimulus detected by the sensor and is further based on the new communication, that a visual stimulus is to be presented. The visual stimulus can be presented.

Abstract: The present disclosure relates to an interface device to control an appliance through a network. The interface device can be device-agnostic and can be incorporated into any suitable appliance. Upon initialization, the interface device can determine the capabilities of the attached appliance and send out update information that can be received by a controller. The controller can send commands designated to control the appliance, which are received by the interface device and translated into appropriate commands that are transmitted to the appliance. The interface device can turn the appliance into a network device, such as a home automation network device.

Abstract: Techniques can relate to generating inferences based on network devices' measuring of environmental data points and generating notifications or controlling devices based on the inferences. One or more environmental data points can be accessed. Each environmental data point in the one or more environmental data points can include one measured by a detector device and that characterizes a corresponding environmental stimulus. At least one of the environmental data points can be indicative of a light intensity or power usage measured by a first device. An inference can be generated based on the one or more environmental data points. A notification or device control can be identified based on the inference. A communication can be generated and transmitted to a second device. Receipt of the communication can cause the second device to present the notification or to be controlled in accordance with the device control.

Abstract: Catalyst composition for the dimerisation of acrylonitrile comprising an organo-phosphorus compound of formula ##STR1## bonded to a matrix of an inorganic oxide having surface --OH groups, especially of silica or alumina. Groups R and Y are hydrocarbyl. The catalyst compositions are prepared by heating the matrix with an appropriate phosphorus compound having group(s) X which react with --OH groups with the elimination of HX. The invention also relates to a process for the dimerisation of acrylonitrile. Main products are 1,4-dicyanobutene-1 and 2-methylene glutaronitrile.
