Abstract: A submunition delivery device including a master electronics module; a submunition module operatively connected to the master electronics module and including a plurality of submunition banks separated by bulkheads. Each of the submunition banks includes a plurality of submunitions; a base plug module operatively connected to the submunition module; and a distributed fuze module operatively connected to the master electronics module to limit a detrimental effect of the plurality of submunitions upon a collision by arming the plurality of submunitions before a dispense action.

Abstract: An injection molding apparatus and a method of injection molding are disclosed. The injection molding apparatus includes a mold sub-platen assembly having a first sub-platen that is attachable to a stationary side portion of a mold base which is mountable to a stationary platen of an injection molding machine. The mold sub-platen assembly also includes a second sub-platen that is attachable to a moving side portion of the mold base that is mountable to a moving platen of the injection molding machine. The method includes attaching a set of guide pins to a mold sub-platen at locations that correspond to guide openings in a mold and installing the mold on the mold sub-platen such that the guide pins extend through guide openings in the first half of the mold and into guide openings in a second half of the mold.

Abstract: A ratcheting micromotor includes a ratchet bar defining ratchet teeth along an edge thereof, and first and second ends in opposition to one another. The first end is adapted to be coupled to an object to be moved. A spring is coupled on one end thereof to the second end of the ratchet bar and adapted to be fixed at another end thereof to a base. A bi-directional actuator configured for linear movement in one of a first direction and a second direction, and when energized has a common yoke coupled to a central portion thereof for movement in correspondence therewith. The common yoke includes teeth formed along an edge and positioned such that its teeth engage a portion of the ratchet teeth. A control system energizes the bi-directional actuator to move, alternately, in the first direction and the second direction.

Abstract: An apparatus used in a fuze device, which includes a MEMS micro-rotor. The micro-rotor of the apparatus may move an explosive material, for example, a fuze material, from an out-of-line position to an in-line position. The micro-rotor includes an integral cavity in which the material may be safely loaded and held in the out-of-line position. At an appropriate time, the fuze device of a fully assembled ordnance may be armed. When the apparatus is activated, the micro-rotor carefully moves the explosive material to the in-line position, where the ordnance is armed.

Abstract: A system for protecting a diaphragm of a microelectromechanical systems (MEMS) device includes a housing coupled to the MEMS device such that its sensing diaphragm is surrounded thereby. A perforated barrier in the housing is adjacent to the sensing diaphragm. A protection diaphragm in the housing has its first side exposed to an external environment of interest, and has its second side facing the perforated barrier and spaced apart therefrom. A fluid is disposed contiguously between the second side of the protection diaphragm and the sensing diaphragm.

Abstract: Systems and methods for a self-regulating power supply for MEMS thermal actuators to achieve maximum actuator displacement while preventing over powering. The present invention includes a power supply configured to regulate electrical input power to a MEMS thermal actuator in order to provide the maximum possible electrical input power. Accordingly, the present invention provides a maximum actuator displacement while preventing device failure from over powering. The present invention utilizes resistivity versus temperature properties for silicon or the like to provide a self-regulating power supply that can be utilized to power a variety of MEMS components without requiring custom actuator control circuits for each type of component.

Abstract: A MEMS type optical switch includes a substrate, the substrate including at least one groove formed therein; first and second optical fibers disposed in the at least one groove, the at least one groove including a widened portion for movement of at least one of the first and second optical fibers; a thermal actuator disposed adjacent one of the first and second optical fibers, the thermal actuator comprising at least one v-beam, a pair of anchors connected to ends of the v-beam, and a yoke disposed in a central portion of the v-beam.

Abstract: A method of sealing an optical fiber in a microchip includes providing a device microchip, a top microchip and an optical fiber; forming a groove in at least one of the device microchip and the top microchip; coating metal on the optical fiber; depositing metal on the groove and top surfaces of the device microchip and the top microchip; depositing solder on the top surface of at least one of the device microchip and the top microchip; placing the optical fiber in the groove; placing the top microchip on the device microchip; and reflowing the solder to form a hermetic seal.
