Abstract: A passive optical methane detection and monitoring system for fixed-position installation is disclosed. The system disclosed can be a compact scannable field of view Near Infrared (NIR) filter photometer to detect and quantify methane concentration. A randomized fiber optic bundle is disclosed that can be used to direct the randomized total optical power from a collection lens to two or more isolated optical channels. Band pass filters isolate a desired wavelength range for transmission measurements for the two or more channels. Also disclosed is a dynamic detection mode that works as a flag to detect a plume of methane moving within the field of view. In other embodiments, a second methane detection device can be added at a second perimeter position to provide a three dimensional concentration grid.

The device includes a determination module (20) for determining a button-held-time parameter associated with the operation of a command button; and a transmitting module (18) that is configured to transmit the button-held-time parameter in association with the command signal.

Abstract: An integrated controller for an operator unit for powering an overhead garage roller door or roller shutter is described. The operator unit comprises a motor, an output drive assembly, a timing assembly unit, and a clutch assembly for providing selective engagement between motor powered operation and manual operation (provided by a chain rotating a chain wheel). The motor is arranged to drive a shaft which, in turn, provides drive to the roller door or shutter assembly (not shown), which includes an axle around which the roller door or shutter is wound. The integrated controller comprises an inverter for receiving a single phase power supply and supplying three phase power to drive the motor; and a drive controller in operable association with the inverter for providing active management of the operation of the motor.

Abstract: The present invention relates to an apparatus and method for driving a moveable closure, such as a garage door. In an initialisation process in a setup mode for the door operator for driving a moveable closure between open and closed positions, the apparatus allows selection of opening and/or closing speeds for the closure from a plurality of predefined stored driving speeds. This selection, or the range of stored driving speeds available for selection, is made in accordance with the type of closure to be driven, and this may be established automatically by detecting certain characteristics of movement of the closure as part of the initialisation process.

Abstract: Drive assembly for a door, gate or barrier, having a rail or track, a trolley for connection to the door, gate or barrier, mountable to run along the rail or track, and a longitudinal drive having a chain or belt connectable in a closed loop arrangement around or within the rail or track. The trolley is provided with an engagement mechanism for selective engagement between the trolley and the longitudinal drive mechanism, whereby the engagement mechanism includes an engagement member arranged for selective movement in a direction substantially transverse to the longitudinal direction of the longitudinal drive and in a direction less than 45° from the plane of the loop of the longitudinal drive. The engagement member includes or cooperates with a cam part arranged for selective rotation about the engagement member, and a camming cooperation occurs between the cam part and the trolley body for converting rotation of the cam part about the engagement member into the required movement of the engagement member.

Abstract: A control system for controlling individual mirrors in a MEMS-based optical switching fabric is presented. The control system includes a position sensitive detector positioned to receive a control beam reflected from individual mirrors of a first mirror array. In some embodiments, the control beam can be time-multiplexed with a calibration beam. The position of the control beam corrected in response to the position of the calibration beam can be compared with a position calculated on the port assignment of the individual mirrors in order to provide feedback to a feed-back based control system for the individual mirrors.
