Abstract: A computer-implemented semantic analysis system for ranking search results has instructions including the steps: receive a query about a first document authored by a person; read in data identifying the first document; read in a second document about the person authored after the first document; identify indicator terms in the second document related to whether or not there is a significant discrepancy between the second document and the first document; read in weighting factors for the identified indicator terms; determine an aggregate weighting factor that decreases with an increasing number of indicator terms found; and calculate a score of how much of a discrepancy there is between the second document and the first document using the weighting factors. When multiple first documents are returned for multiple persons, present the links in order from high score to low score.

Abstract: This invention teaches a multi-sensor quality inference system for additive manufacturing. This invention still further teaches a quality system that is capable of discerning and addressing three quality issues: i) process anomalies, or extreme unpredictable events uncorrelated to process inputs; ii) process variations, or difference between desired process parameters and actual operating conditions; and iii) material structure and properties, or the quality of the resultant material created by the Additive Manufacturing process. This invention further teaches experimental observations of the Additive Manufacturing process made only in a Lagrangian frame of reference. This invention even further teaches the use of the gathered sensor data to evaluate and control additive manufacturing operations in real time.

Abstract: An HVAC system utilizes one or more modular heat pump units installed within an outer wall or corner of a building, and one or more active registers. A central hub, which can be integrated into a modular HVAC unit, receives input from thermostats and sensors in the building and adjusts operation of the modular HVAC units and active registers to distribute conditioned air throughout the building. The system provides convenience and comfort of a traditional split HVAC system with significantly reduced installation and maintenance costs. The modular HVAC unit includes an interchangeable cartridge that contains the active components of a heat pump. Cartridges of different capacities can be installed as required, and are easily swapped out for maintenance, servicing, and replacement. A user can control the system using traditional-style thermostats and with a smart phone, tablet or computer. A cloud server provides backup services and remote access to the system.

Abstract: A sequential mold lifter for a molded part forming device comprises at least first, second and third lifter segments that slidably engage one another. The first and third lifter sections are positioned on opposite sides of the second section and slide upwardly and inwardly on inclined lifter surfaces on the second lifter section. Separate actuators extend all of the lifter sections to a first extended position and then extend the first and third actuators upwardly and inwardly beyond the second actuator to a second extended position. The relative movement of the lifter sections dislodges the molded product from the mold and then dislodges the product from the lifter. The inclination of the actuators can vary with the positions of the lifter sections. Movable slides support the actuators but permit variation in the inclination of the actuators.

Abstract: A power switch for use with a personal locator beacon (PLB), or an emergency position indicating radio beacon (EPIRB), that prevents accidental activation of the beacon to prevent false alarm transmission of emergency signals. The personal locator beacon includes electronic circuitry housed in a portable hand-held housing that includes a fail safe power switch which has a lever arm that is selectively movable between first and second offset recessed cavities formed in the housing. The lever arm is rotatable about a shaft between an "off" position wherein the lever arm is received within the first cavity, and an "on" position wherein said lever arm is received within the second cavity. An edge portion formed by the offset cavities stops the lever arm from rotating from the first position to the second position unless the lever arm is manually moved laterally along the shaft to clear the edge portion.

Abstract: A hand-held water activated strobe light which may be used in rescue or emergency operations in peacetime or in a combat zone. The light includes a watertight housing with a high intensity bulb which flashes white light. Interchangeable blue and infrared filters attached to a flash guard body can be used with the bulb for filtering various wave lengths of light spectrum in combat situations and for both 360 degree or line-of-sight transmission. The strobe light is water activated and includes a sensor that deactivates the light during daylight hours. A memory latch circuit maintains activation of the light once the water activated switch comes in contact with water. A power saving circuit permits the use of alkaline batteries in place of mercury batteries, which also provides for environmental protection.

Abstract: A survival radio for use for transmitting and receiving information for search and rescue having an improved structural housing assembly for increased reliability to prevent moisture and water intrusion, while permitting use of the device in any ambient air pressure. The housing assembly includes a tongue and sealed groove connections joined by deforming the tongue in a pliable state, housing assembly apertures covered by a deformable flexible sealable plastic panel to permit manual actuation of internal switches and an air vent that has a porous plug permitting air pressure equalization between the inside and outside of the housing assembly, while preventing water intrusion.

Abstract: An improved search and rescue transponder having an improved housing assembly that permits the device to be turned on or off by rotating one segment of the housing relative to the other for ease of use even with heavy or bulky gloves. In addition, the housing assembly exterior surface includes a plurality of longitudinal ridges for ease in gripping. The housing assembly includes an upper housing and lower housing joined by a retaining ring and O-ring seal, eliminating the need for fasteners for manufacturing efficiency. The lower housing includes quick disconnect that attaches to a mounting disk affixed to a ship or life raft. The mounting disk includes a plurality of resilient fingers which act in conjunction with cam surfaces on the flange of the lower housing, which when rotated together allow for a quick disconnect.
