Abstract: A barrier operator monitoring system includes a barrier operator system and a cloud processing platform. The barrier operator system includes a movable barrier, sensors configured to measure data regarding the barrier operator system, and a barrier operator. The barrier operator is configured to move the movable barrier, detect a loss of a data connection between the barrier operator and the cloud processing platform, collect measured data from the sensors, perform wavelet transformation on the measured data, store coefficients of the wavelet transformation, and transmit, upon restoration of the data connection, the coefficients. The cloud processing platform is configured to receive the coefficients, reconstruct a representation of the measured data, compare the representation of the measured data to model data, detect an anomaly in the barrier operator system based on the comparison, and transmit a notification from the cloud processing platform to a user device.

Abstract: A therapy light comprises a housing and a circuit board mounted within the housing and having light emitting diodes mounted thereon. Airflow apertures in the circuit board are disposed adjacent the light emitting diodes such that the front face and the back face of the circuit board are in airflow communication one with the other. The ratio of the cumulative cross-sectional area of the airflow apertures to the cumulative cross-sectional area of the light emitting diodes is greater than about 3:2. In use, a fan causes air to flow into an intake ventilation opening, from the intake ventilation opening to the circuit board, through the airflow apertures in the circuit board, and out of an exhaust ventilation opening, to thereby cool the light emitting diodes.

Abstract: A work light comprises an elongate circuit board having a length extending between a connection end and a free end and a width extending between a left side and a right side. A light emitting diode is mounted on the elongate circuit board. An elongate protective cover has a length extending between a mounting end and a free end, and generally surrounds at least most of said elongate circuit board. The protective cover may comprise a suctioning tube having a fluid ingress and a fluid egress. The suctioning tube is connectable at the mounting end to a source of suction.

Abstract: A method of producing an image on a display screen comprises the steps of generating at least one wavelength of light in a selected wavelength band of red light in the wavelength range from about 620 nm to about 655 nm and/or yellow-green light in the wavelength range from about 530 nm to about 580 nm, and directing the generated light to a target object containing an accumulation of a fluorescable biomarker, such that the generated light reaches the fluorescable biomarker and excites the fluorescable biomarker to thereby cause it to emit fluoresced light within a characteristic wavelength band. The fluoresced light from the fluorescable biomarker is captured. A digital data file representative of the captured fluoresced light is created. A representative image is formed on a display screen from the digital data file. An apparatus for generating an image on a display screen using the above method is also disclosed.

Abstract: A liquid-containing heat filter for use with a high-intensity light, said liquid-containing heat filter comprising a substantially hollow reservoir for receiving heat-filtering liquid therein, the reservoir comprising a first optically transparent member, a second optically transparent member, and a peripheral frame for receiving and retaining said first optically transparent member and said second optically transparent member, heat-filtering liquid disposed in said substantially hollow reservoir, and a first resiliently deformable member interposed in trapped relation between the first optically transparent member and a first portion of said peripheral frame, wherein, in use, when the heat-filtering liquid in the reservoir raises in temperature due to the heating effect of the high-intensity light, the first resiliently deformable member is compressed to thereby allow the outward movement of the first optically transparent member due to expansion of the heat-filtering liquid.

Abstract: An apparatus for precluding plant trunks from freezing comprises an electrically powered heating means, for placement adjacent a plant trunk, to thereby warm the plant trunk. An insulating means is provided for surrounding the electrically powered heating means and the plant trunk, to thereby retain heat generated by the electrically powered heating means around the plant trunk.
