The present disclosure provides a system and method for managing a vehicle electrical system providing power to auxiliary systems. The system comprises a power control device with the ability to control the power to multiple auxiliary systems. The device has one or more sensor inputs for reading the system voltage and other data. The device can be configured with preset voltage thresholds for turning individual accessories on or off at predetermined voltage levels, or otherwise entering shutdown procedures. The system may also comprise a computer that is running dedicated software for managing the system and reconfiguring the device behavior.

Intelligent vehicle power control system and method

A system for controlling the deglycerolization of red blood cells includes a cell sorter having multiple fluid channels each having a unique cross-sectional area for directing a fluid mixture consisting essentially of a saline solution and a plasma solution having glycerized red blood cell products through one or more of the fluid channels based on the sizes of the red blood cell products. An optical energy source illuminates the fluid mixture in the cell sorter, whereupon an optical detector generates a data signal in response to receiving light signals that propagate through the fluid mixture. A processor generates a control signal in response to receiving the data signal that is used by a servo-controlled device to control the ratio of the saline and plasma solutions in the fluid mixture so that the red blood cell products substantially flow only through one or more of the fluid channels having particular cross-sectional areas.

System for controlling deglycerolization of red blood cells

A colorimetric red blood cell sensor provides an automatic system for deting and preventing the further mixing of red blood cells and plasma. The sensor includes a processor that controls blue and red light sources so that they collectively generate pulsed blue and red light signals that are directed through blood serum held in an optically transparent container. The red and blue signals are 180 degrees out of phase, and hence staggered, with respect to each other. A photodetector system detects the pulsed red and blue light signals and generates output signals representing the intensities of the staggered signals received by the photodetector system. A microprocessor determines the ratio of the intensities of the red and blue light signals detected by the photodetector system. If the ratio exceeds a limit, the microprocessor generates a fluid control signal that prevents further mixing of red blood cells and plasma.

A system for measuring toxicity levels of a solution includes a water proof sample container transparent to visible light which holds an aqueous test solution containing bioluminescent organisms. A light tight chamber has a cavity which holds the sample container and includes a light port. A stress generating system positioned in the sample container generates pressure pulses which stimulate the organisms to generate light emissions. A light detector system mounted to the light tight chamber in a light tight manner detects light emissions generated in the sample container which propagate through the light port and are received by the light detector system. The light detector system generates an electric pulse in response to detecting each detected light emission. A controller enables the stress generating system and the light detector system, and then counts the electric pulses within a predetermined period of time. The system may further include a fiber optic bundle for propagating light from the light port to the photodetector element in the light detector system, and an optical attenuator supervised by the controller to limit the intensity of light irradiating the photodetector within the linear response range of the element, and to prevent ambient light from saturating and damaging the photodetector.

Bioluminescent bioassay system

A thermal neutron detector comprises an enclosure containing a helium-xenon gas mixture, an optical fiber, and an electrode arranged to detect ion particles. The optical fiber detects photons generated by a reaction of the gas mixture with neutrons passing through the enclosure. The reaction also generates ion particles that are detected by the electrode. A coincidence detector generates an output signal corresponding to the correlation of ion detections from the electrode with photon detections from the optical fiber, rejecting signals generated from the electric field that are not correlated with photon detections.

An apparatus for detection of thermal neutrons includes a volume of gas which includes .sup.3 He. A wavelength shifting optical (WSO) fiber is disposed to receive ultra-violet (UV) photons generated by reactions between neutrons and .sup.3 He. UV photons are absorbed within the WSO fiber to produce longer wavelength fluorescence generated photons that propagate within the WSO fiber. A photodetector is disposed to receive fluorescence generated photons from at least one end of the optical fiber and provide an output signal corresponding to neutron detection.

Detection of thermal neutrons through the use of internal wavelength

A bioluminescent detector is disclosed for detecting and measuring in situ bioluminescence generated by marine microorganisms. The detector includes a laminar flow chamber, a turbulent flow chamber in fluid communication with the laminar flow chamber, and a photon detector network positioned with the turbulent flow chamber. The detector is dropped over the side of a ship which may be underway and sinks at constant velocity. As the detector descends, ocean water flows through the laminar flow chamber and then into the turbulent flow chamber where fluid turbulence subjects any bioluminescent organisms present to shear stress, causing them to generate photons that are detected by the photon detector network.

Bioluminescent detector

A solid state digital and analog circuit which is connected between a two-way radio, public address system etc. and the battery in a police car, emergency vehicle, tow truck or fire truck to prevent the same from inadvertently draining all the power from the battery when the vehicle is left unattended for long periods of time. When the ignition is turned off, a timer in the circuit begins counting and after a prescribed amount of time, e.g. between one and twelve hours, a relay disconnects the auxiliary equipment from high current of the battery. When the ignition is turned on the circuit immediately re-connects the auxiliary equipment and the battery.

Apparatus is provided for analyzing the structure of light burst activity ich is generated by a particular light source, such as a group of bioluminescent organisms. The apparatus includes a photon detector for detecting discrete photons of light occurring proximate to the source during each sampling time in a series of sampling times, and further includes a counter coupled to the photon detector for providing successive photon counts, a photon count being the number of discrete photons detected by the photon detector during one of the sampling times. A pulse height analyzing device is coupled to the counter for providing a distribution of the photon counts over the sampling time series.
