Abstract: A system adjusts detection parameters used to process a signal from a PIR sensor to reduce false triggers. A detection module receives a sensor output signal from a PIR sensor and inputs from environmental sensors, including a temperature sensor. The detection module adjusts detection parameters of a bandpass filter and/or a thresholod comparison module based on the inputs from the environmental sensors. The detection module generates a motion presence signal that indicates whether motion has been detected and that compensates for external environmental factors.

Abstract: An intelligent streetlight may include a modem capable of communicating on a mobile communications network. The intelligent streetlight may be communicate with a network operations center (“NOC”) via the mobile communications network. In some aspects, the intelligent streetlight configures the modem to transmit on the mobile network based on multiple types of network provisioning data. For example, the modem may have a network configuration, such as a low-bandwidth mobile data plan, based on stored provisioning data. The modem may reconfigure the modem based on additional provisioning data for an additional network configuration, such as a high-bandwidth mobile data plan. In some cases, the additional provisioning data is requested by the streetlight from the NOC. In some cases, the NOC may provide the additional provisioning data to multiple intelligent streetlights, such that the multiple streetlights are each reconfigured in a short period of time.

Abstract: Aspects are provided for controlling outdoor lighting systems using a photocontrol interface that can be connected to a motion sensor and a luminaire driver or ballast. In some aspects, a dimming control node is electrically and communicatively coupled to a motion sensor via wired connections to a photocontrol interface. The dimming control node is also communicatively coupled to a luminaire ballast or driver. The dimming control node can provide power to the motion sensor. The dimming control node can also receive sensor data from the motion sensor via one of the wired connections. The dimming control node can determine a sensor output state of the motion sensor from the received sensor data, and can select a dim-level configuration corresponding to the determined sensor output state. The dimming control node can cause the luminaire ballast or driver to implement the selected dim-level configuration.

Abstract: Lighting control devices, network systems, and methodologies, including methods for providing closed-loop dimming control of such systems, are described. In some examples, disclosed methods and device configurations may include an intelligent photo control configured to accept target dimmed fixture wattage value commands from a user, and provide closed-loop control at the fixture to achieve that target wattage via real-time adjustment of the 0-10V dimming control signal sent to the LED driver. As such, the need for trial-and-error adjustments of the 0-10V analog control voltage, or derivation of dim voltage to fixture wattage response curves in order to achieve a desired fixture wattage level, may be reduced or eliminated.

Abstract: Upgraded firmware for a microcontroller is created and encrypted to construct a file (116) that can be distributed and installed by technicians in the field. The encryption includes character encryption (210) of the data as well as a second level of block encryption (216). Within the encrypted file (116), information about the firmware and the target microcontroller (104) is included. The distributed firmware file (116) is stored on a portable device, such as a PDA, that can communicate with the target microcontroller (104) to effect a firmware transfer from the PDA (112) to the microcontroller (104). The microcontroller (104) includes a programming routine that receives the encrypted data stream from the PDA and decrypts the data before storing the new firmware image. The programming routine also identifies when updating the firmware has left the firmware in an unusable condition and prevents operation of the microcontroller until the firmware is restored.

Abstract: A heating, ventilation and air conditioning (HVAC) device (104) which includes both heating and cooling operating modes provides an easy-to-use interface (110) for selecting the operating parameters of the device (104). The interface (110) allows the input of a setpoint temperature at which the HVAC device (104) conditions the ambient temperature of a space (102). A mode switch-over algorithm (200) uses the setpoint temperature, the sensed temperature from the conditioned space, and prestored threshold values that depend on the device's operating capacities, to determine when to change the device between heating and cooling modes. Also, within each of the respective modes, a heating (300) or cooling (400) algorithm controls the engaging and disengaging of the heating and cooling elements of the device (104) to maintain the temperature of the conditioned space (102) within a desired comfort zone.

Abstract: A microcontroller (122) uses a two-stage algorithm to sample the state of an AC switch (124) connected directly to an input pin (126). An AC line signal (102) is sampled by a pre-filtering routine that samples the AC line signal (102) to determine when a peak or trough is occurring and generates a trigger signal at or near the occurrence of a peak or trough. By basing the triggering signal on the state of the AC line signal (102), the triggering signal is independent of any shift of the phase angle of the AC line signal (102) and the microcontroller's operating clock (152). A switch sampling routine (204) is initiated at each occurrence of the triggering signal which samples the state of the AC switch (124). Successive sampled values are shifted into a shift register (150) on the microcontroller (122).
