Method for detection and recognition of fog presence within an aircraft compartment using video images
Detecting video phenomena, such as fire in an aircraft cargo bay, includes receiving a plurality of video images from a plurality of sources, compensating the images to provide enhanced images, extracting features from the enhanced images, and combining the features from the plurality of sources to detect the video phenomena. Extracting features may include determining an energy indicator for each of a subset of the plurality of frames. Detecting video phenomena may also include comparing energy indicators for each of the subset of the plurality of frames to a reference frame. The reference frame corresponds to a video frame taken when no fire is present, video frame immediately preceding each of the subset of the plurality of frames, or a video frame immediately preceding a frame that is immediately preceding each of the subset of the plurality of frames. Image-based and non-image based techniques are described herein in connection with fire detection and / or verification and other applications.

Fluid monitoring device
InactiveUS7327273B2Limited effectTimely attentionControlling traffic signalsMedical devicesCatheterEngineering
This invention relates to a device to monitor the administration of a fluid through a conduit, such as intravenous fluid, and detect the completion of fluid delivery by monitoring the fluid level inside a chamber. The device will monitor, through an optical fluid sensor comprising a radiation source, two sensors, a logic means, and an indicating means, the bottom half of any “user supplied” drip chamber that is normally full during the administration of fluids. When the fluid level in the chamber drops below a predetermined level, the indicating means will initiate an electromechanical device that releases a pinching device to occlude the conduit. The pinching device is a rotary pincher that derives its force from a torsion spring and is held in the open position by the electromechanical device.

Flame sensor with dynamic sensitivity adjustment
InactiveUS6013919AIncreased ultraviolet sensitivityEliminate needInternal-combustion engine testingContinuous combustion chamberSignal conditioning circuitsUltraviolet lights
The present invention provides a flame sensor having dynamic sensitivity adjustment, wherein the sensitivity of the flame detector can be adjusted by varying the gain of a signal conditioning circuit associated with the flame detector. The flame detector includes a photodiode, such as, for example, a silicon carbide (SiC) photodiode, that, when exposed to electromagnetic radiation having a wavelength in the range of from about 190-400 nanometers, and preferably within the ultraviolet range. The photodiode generates a photocurrent proportional to the ultraviolet light intensity to which it is exposed. The output of the photodiode is processed and amplified by signal conditioning circuitry to produce a signal indicative of the presence of a flame. Moreover, a cutoff wavelength for silicon carbide photodiodes is preferably in the range of about 400 nanometers, which renders the photodiode "blind" to potentially interfering blackbody radiation from the walls of the turbine.

Alarm having illumination feature
An improved alarm system that has an added illumination feature allowing locations to be both scanned for intruders, and illuminated upon intrusion detection. This illumination feature imparts a number of advantages over current alarm systems. Notably, lighting the area where an intrusion is detected can aid in identifying the intruder and possibly even intimidating him / her into leaving, especially during night time or other conditions of low ambient light. Also, the illumination feature can be configured so as to be activated independent of the alarm itself. In this manner, light can be provided during emergencies or any other time that users require additional light.
