Patent number: 4964040Abstract: The computer hardware executive is a special purpose associative processor hich interfaces to the memory bus of a digital computer to provide high-speed execution of executive functions. These functions include task registration, task synchronization, normal, time-dependent and time-critical event registration and triggering, hierarchical event-to-semaphore translation, and buffer allocation. The programmer invokes an executive function by accessing the address in the hose computer address space dedicated to that function. The data written to or read from that address is the function operated or result, respectively. The hardware executive maintains task and event tables internally within its associative memory. The memory is organized such that the same field bit position of all table entries is accessed in parallel within a microinstruction cycle. Searches are performed by sequencing through the bit positions of interest.Type: GrantFiled: January 3, 1983Date of Patent: October 16, 1990Assignee: United States of America as represented by the Secretary of the NavyInventor: Dwight R.

Patent number: 4721836Abstract: An improved apparatus for annealing an ion-implanted semiconductor sample duces the deleterious side effects otherwise associated with the process. A semiconductor sample, fabricated, for example, from indium phosphide or gallium arsenide, is set upon the fingers of a carrier which is displaced to the interior of an elongate furnace having its internal temperature maintained at the proper annealing temperature. Next, the fingers are rotated and the sample is placed on a number of razor blade-like edges extending up from an internal rack. The carrier is withdrawn and the sample is quickly brought to the annealing temperature for the precise period of time usually no more than 20 seconds. After the exact annealing period, the carrier is reintroduced and the fingers are rotated to lift the sample from the rack and the sample is withdrawn.Type: GrantFiled: May 14, 1986Date of Patent: January 26, 1988Assignee: The United States of America as represented by the Secretary of the NavyInventors: Carl R.

Patent number: 4717256Abstract: In a fiber optic rate sensor employing a Sagnac ring circuit wherein an ocal source launches an optical signal which is divided into two equals signals which are coupled in opposite directions through a multi-turn fiber optic coil to provide two counter-propagating optical signals. The two counter-propagating optical signals are coupled to a photodetector after passing through the multiturn fiber coil. The signals detected at the photodetector have traversed identical optical paths between said source and said photodetector and have undergone a Sagnac phase shift directly related to the rate of rotation of the fiber coil about its axis in inertial space. The two counterpropagating signals are phase modulated by a phase modulator at one end of the fiber optic coil and the output of the photodetector undergoes signal processing in a signal processor to produce a rate output directly related to the rate of rotation of the fiber coil.Type: GrantFiled: July 21, 1986Date of Patent: January 5, 1988Assignee: The United States of America as represented by the Secretary of the NavyInventors: Donald Ensley, Hiroshi Satake

Patent number: 4717862Abstract: A pulsed illuminator projector for reducing the reverberation levels of rected ligh by illuminating a lamp that is pulsed on and off at a specified rate and for a specified time duration. The critical factor is controlling the amount of time the light is on versus amount of time it is off, and the frequency at which the lamp is pulsed on. The pulsed illumination projector device reduces the amount of backscatter from particulate matter such as water, zooplankton, dust, fog and the like which causes a significant amount of light to reflect back toward the source thereby reducing visibility. Backscatter is reduced through the reduction of direct incident light. As the backscatter is reduced, the distance which objects can be detected is increased. Illumination is controlled directly by pulse length and repetition rate. The device is completely portable and can be hand held item as well as mounted on a vehicle and operable in gaseous or liquid atmospheres.Type: GrantFiled: November 19, 1984Date of Patent: January 5, 1988Assignee: The United States Government as represented by the Secretary of the NavyInventor: William B.
