摘要:
Method and apparatus for limiting optical radiation to an optical sensor are disclosed for protecting the sensor against damage from high intensity optical radiation. A fixed electric field is established between a pair of spaced electrodes by connection of the electrodes to a DC voltage source. Small solid particles oscillate back and forth in the electric field between the electrodes. Incident optical radiation is focused at a focal plane at the oscillating solid particles, and energy transmitted through the oscillating particles is focused at the optical sensor. The transmittance of the particle-containing space is substantially constant for incident optical radiation intensity up to a threshold level below which the sensor is undamaged by the radiation. Above the threshold, oscillating particles are heated to a high temperature for vaporization, ionization and thermal expansion thereof for increased scatter and absorption thereby limiting optical radiation to the sensor to an intensity below which damage to the sensor occurs.
摘要:
A system and method for detecting vibration information by receiving electromagnetic radiation reflected or emitted from a target object at a photodetector array to provide real-time imaging of the target object. The detected radiation may be visible light, infrared or ultraviolet radiation, and/or of other desired frequency ranges. The detected radiation is AC-coupled to isolate components relating to oscillations of the target object from components relating to ambient radiation, e.g. background sunlight, and is digitized, stored, and subjected to processing such as a Fourier transform to generate outputs representative of frequencies of oscillation, which can be used for analysis of the target object.
摘要:
There is disclosed herein a technique for detecting and/or identifying a particular object from which electromagnetic radiation is emitted or reflected at an intensity which fluctuates in accordance with a frequency pattern unique to that object. In accordance with the technique, the fluctuating electromagnetic radiation is detected by suitable equipment which can operate across an optical bandwidth extending from the ultraviolet (200 nm) to the infrared (14 micrometers) spectrum. The detected electromagnetic radiation is converted to an electrical signal having the same unique frequency pattern as the electromagnetic radiation itself. This electrical signal, its frequency pattern serving as an identifying signature of the object in question, is used to detect, track, and/or identify the object.

A sharps dispensing and disposal system configured for mounting within an interior of an enclosure is disclosed. The sharps dispensing and disposal system includes a dispensing chamber and a disposal chamber that are each configured to be substantially enclosed within the interior of the enclosure. The dispensing chamber and the disposal chamber are defined by separate containers that are each formed from a leak resistant material.

A cherry sizing process and apparatus in which cherries are sized in stages, with each stage including substantially parallel rollers and with each stage having a gap different than the other stages. Preferably, the larger size cherries are removed before the final sizing stage. In addition, the larger cherries are preferably removed as an overs product, i.e., as the cherries which do not pass through the gap between rollers at the stage at which the larger cherries are removed. The different gap settings can be set based upon recommended ranges which have been determined based upon the recognition that a particular gap will have a predictable removal efficiency for each of various cherry sizes. In addition, the gap can be selected utilizing a simulator which determines the result of each sizing stage based upon statistical information concerning the size distribution of cherries to be sized and the removal efficiencies of each stage for each cherry size. Based upon the results predicted by the simulator, the gap or other sizing conditions (such as the speed of the roller) can be refined.

An improved apparatus and method for making a fast thermal response mold is disclosed. The apparatus has a plurality of rows with each row having a plurality of cavities. Each cavity in each particular row is interconnected by bores to allow a thermal medium to pass therebetween in a serpentine manner. Each cavity has a sleeve fixed therein and adapted to fit a mold. The sleeve eliminates the need for O-ring sealing means utilized in prior fast thermal response molds.

An electronic sectionalizer for a branch line of a high voltage power distribution system has a resettable actuator for unlatching a trunnion member and release of a sectionalizer tube toward a disabled or drop-out orientation. The actuator includes an elongated, spring-loaded plunger normally held by a latch in loaded position, and a solenoid or the like is provided to shift the latch and enable movement of the plunger toward a released position for simultaneous swinging movement of the trunnion member. In certain forms of the invention, the plunger is directly engageable with a wall of the trunnion member, while in other embodiments of the invention mechanical advantage is provided by use of an elongated lever which is disposed in the path of the plunger and which bears against the trunnion member for initiating rotational movement of the latter.
摘要:
A pivot mechanism for drop-out of an electronic sectionalizer tube from an upper contact of mounting structure is arranged so that substantially the entire force released by an actuator fired by a sectionalizer logic circuit immediately causes the tube to drop away and disengage the upper contact. The actuator is mounted on a lower portion of the tube and has a pin that strikes a trunnion pivotally interconnecting a lower contact of the mounting structure and a lower portion of the tube, and the pin of the actuator strikes the trunnion at a location between the pivotal connections of the trunnion so that immediate, downwardly directed motion of the sectionalizer tube away from the upper contact is assured. The pivot mechanism reliably ensures successful drop-out of the tube regardless of adverse environmental conditions and with minimal reliance upon a spring or the effects of gravity.
摘要:
A method of making a mold frame is disclosed. A plurality of rows of cavities are formed in a mold plate. The cavities of each row are interconnected by a bore. The row bores are interconnected by cross bores. The cross bores are selectively sealed off so that a cooling medium going through the mold frame follows a serpentine path.
