Abstract: An example of an apparatus to provision a decentralized network is provided. The apparatus includes a memory storage unit to store a status identifier to indicating whether the apparatus is in a non-provisioned state or a provisioned state. The apparatus further includes a beacon transmitter to transmit an outgoing beacon signal and a beacon receiver to receive an incoming beacon signal from an external device. The apparatus includes an infrared communicator to send and receive signals with the external. In addition, the apparatus in the non-provisioned state includes an election engine to determine a priority relative to the external device upon receiving the incoming beacon signal. The apparatus also includes a provisioning engine to change the status identifier from the non-provisioned state to the provisioned state and to send a provisioning key to the external device to join a network upon confirmation the external device is within the secure space.

Abstract: A controller based apparatus mounted on the ceiling of a room to control the lighting level of a space includes an image sensor/detector for capturing spatial data, ambient light data, and images and an optical element which allows sufficient light to pass through such that the image sensor can collect sufficient data to provide the controller in order to extract motion events, occupancy data, and/or ambient light readings while maintaining the privacy of individuals by reducing the optical resolution of the image sensor such that fine features, such as facial features or other identifiable features of people or objects, cannot be recorded or stored.

Abstract: An example of an apparatus is provided. The apparatus includes a light source to emit light. The apparatus further includes a light source controller to control the light source. The light source controller is to change an intensity of the light emitted by the light source. In addition, the apparatus includes a low resolution sensor to measure light data from a reflection of the light off a wall. Also, the apparatus includes a memory storage unit to store the light data and corresponding control data. The apparatus includes an image processing engine to locate and to classify the wall based on the light data and the control data.
