    摘要: A vertical color filter sensor group formed on a substrate (preferably a semiconductor substrate) and including at least two vertically stacked, photosensitive sensors, and an array of such sensor groups. In some embodiments, a carrier-collection element of at least one sensor of the group has substantially larger area, projected in a plane perpendicular to a normal axis defined by a top surface of a top sensor of the group, than does each minimum-sized carrier-collection element of the group. In some embodiments, the array includes at least two sensor groups that share at least one carrier-collection element. Optionally, the sensor group includes at least one filter positioned relative to the sensors such that radiation that has propagated through or reflected from the filter will propagate into at least one sensor of the group.

    摘要: A bone-conduction transducer in the form of a band encircling around a head carries piezoelectric elements that excite the head with signals that correspond to speech and/or audio. The head vibrates according to its modes of vibration, primarily of the skull. Direct connection to bones of the skull, such as by implant or extreme pressure, is not needed. Thus, comfort is enhanced, and so is effectiveness. The incoming signal is segmented into frequency bands, one for each of the modes of vibration of the head of interest. For each frequency band, the signal is processed to pass signals to the piezoelectric elements in a particular way to excite the relevant mode of vibration. Thus, sound is sensed by the user through vibration of the head. A head band carrying transducer elements may also be used to sense spoken sound, as a microphone. The piezoelectric transducer elements generate electromagnetic signals in response to the vibration of the head (which vibration is characterized by its modes) excited by speaking. The electromagnetic signals are processed to identify the modes being excited, and the intensity of the excitations. This mode signal is analyzed according to a model to determine a speech signal that has generated the head vibrations. That speech signal is generated as an electromagnetic signal, and may be sent as an output signal.

    摘要: The present invention relates to a system for recycling a halocarbon composition which generally removes a halocarbon composition from a first source to purify the halocarbon composition and injects the halocarbon composition to a second source. The present invention is particularly useful for recovering and recharging of a commonly used halocarbon composition, Halon 1301. The invention comprises a first line having a first and second end where the first end of the first line is connected to the first source. The first source has the halocarbon composition contained therein. A vapor recovery unit connects to the second end of the first line for permitting the halocarbon composition to be transported from the first source to the vapor recovery unit for compression. A second line connects the vapor recovery unit to a recovery bottle. The recovery bottle is cooled by a cooling system integrally connected thereto for separating the nitrogen from the halocarbon composition. Once the halocarbon gas has been purified, a return line which connects the recovery bottle to permit the purified halocarbon composition to return to a second source for later usage.

    摘要: A flammability tester for samples in the milligram range. A tube with a lower pyrolyzing region, or pyrolyzer, contains a sample that is heated to thermally degrade in the absence of oxygen, or pyrolyzed, to produce fuel gases. An inert gas carries the fuel gases to an upper combustion region, or combustor, where oxygen is measured into the gas flow containing the inert gas and fuel gases. Combustion of the fuel gases occurs at a temperature where the reaction time for almost all of the fuel gases is at or below 10 seconds. Under these conditions, the combustor volume need for complete combustion is small, permitting the fuel gases to be oxidized as they are liberated and travel from the pyrolyzer into the combustor in what is essentially sequential flow. Complete combustion in such a small volume produces a large decrease in the oxygen content of the gases emerging from the combustor, allowing the use of a simple inexpensive oxygen analyzer to measure the oxygen content of the gases emerging from the combustor. Oxygen depletion can be used to determine flammability parameters of the sample. The tester can be fitted with a thermometer to measure the combustion temperature of the pyrolyzed sample. The tester may also be configured to use a carbon dioxide analyzer to measure additional flammability parameters. The tester may also be combined with a separate thermogravimetric analyzer to yield further flammability parameters where the mass loss rate of the pyrolyzing sample is needed.

    摘要: A transducer senses sounds produced by a talker or other source and measures acceleration of air. Enhancement of acceleration is accompanied by reduction of the portion of the sound energy that escapes from the regions around the transducer. The result is a high sensitivity transducer, with increased privacy for use in communication systems, especially cell phones and in a multi-person environment. A pressure sensor array with a weighted output is sensitive to sound from a source talker only, and not to acoustic background noise, and not to a local loudspeaker. The weighted signal is a source sum pressure signal. The array produces a signal (using a different weighting) that corresponds to an estimate of a derivative of pressure. The derivative signal is proportional to the volume velocity fluctuations produced by the source. This signal is enhanced, rather than reduced. A local loudspeaker is driven to make the source sum pressure signal as small as desired. The loudspeaker is driven to produce volume velocity fluctuations approximately equal and opposite to those produced by the source. No compression of air arises due to the talker, and no sound is radiated into the far field. All happens because the system is driven to reduce the source pressure sum signal to below a desired threshold. It is not necessary to directly measure the volume velocity fluctuations of the talker source.
