Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: A sensing device transmits wireless signals when an error between at least one sampled parameter value and at least one predicted parameter value is too great, such that the sensing device transmits wireless signals to a load control device using a variable transmission rate that is dependent upon the amount of change in a value of the parameter. The sensing device uses the one or more estimators to determine the predicted parameter value, and may transmit the estimators to the load control device if the error is too great. The load control device uses the estimators to determine at least one estimated parameter value and controls the electrical load in response to the estimated parameter value. The sensing device may comprise, for example, a daylight sensor for measuring a total light intensity in the space around the sensor or a temperature sensor for measuring a temperature around the sensor.

The opaque structure may be formed from an opaque material or a transparent material with an opaque coating. The light sensor may be mounted in a support structure that has been optically aligned with the aperture.

Abstract: An apparatus using reconfigurable integrated sensor elements with an efficient energy harvesting capability is described. Each sensor element has sensing and energy harvesting mode. In the sensing mode, the sensor element measures an environmental characteristic by generating electrical charge and outputs a time-encoded signal indicative of the measurement. In the energy harvesting mode, the sensor element itself is used to harvest energy from ambient energy source and makes it available to other sensor elements or circuit components. The sensing element is switched from the sensing mode to the energy harvesting mode when the electrical charge reaches a predetermined threshold. An image sensor device using asynchronous readout for harvesting energy from incident light while generating images is also described.
