Abstract: Various implementations of an extinguishable, solid propellant divert system for a flight vehicle are disclosed. Also disclosed are methods for using the divert system to control the flight of a flight vehicle. In one implementation, a divert system includes a hot gas generator pneumatically linked to one or more divert thrusters and an extinguishment valve. The extinguishment valve can be opened to rapidly depressurize the hot gas generator and extinguish the solid propellant burning inside. In another implementation, a method of controlling the trajectory of the flight vehicle includes repeatedly igniting and extinguishing the solid propellant in a hot gas generator and using the hot gas to provide divert thrust for the flight vehicle.

Abstract: A method and system for managing occupancy of a workplace location in time is provided. The method comprising receiving a reservation request comprising an expected location identifier of the expected location and a time slot indication of the time slot; generating and transmitting a refusal of the reservation request to the client device if a location counter is equal to a full capacity of the location; displaying a calendar user interface with expected location badges of the expected locations for the plurality of users for each day using personal thumbnails, the personal thumbnails being located in the calendar user interface based on the reservation request received from each client device; generating and displaying a spatial-relationship visual indicator which maps a selection of the personal thumbnails related to users having all selected one specific location from the received expected locations.

Abstract: An attitude control system for a guided missile includes a gas generator, an accumulator coupled to the gas generator, and a valve positioned between the gas generator and the accumulator. The gas generator contains propellant that burns to provide hot gas to pressurize the accumulator. The valve is opened to recharge the accumulator with hot gas and closed when it is full. A vent valve can be included to extinguish the propellant in the gas generator. The accumulator can be coupled to thrusters that use the stored hot gas to adjust the attitude of the guided missile.

Abstract: A level gauge for determining the level of a liquid in a vessel includes lenticular lens assembly allowing a plurality of level indicator flags enclosed therein to be viewed from a wide angle. The indicator flags have an elongated body manufactured from a sheet of material, and form a central pocket for retaining a magnet, and pins on either end for mounting within a frame. A mounting frame positions the lens assembly whereby an open channel is formed between the lens assembly and a back plate. The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags.

Abstract: Embodiments of the subject invention relate to a method and apparatus for signal processing that reduces the average power used in a small size, frequency modulated continuous-wave (FMCW) radar. Such a small size, frequency modulated continuous-wave (FMCW) radar is referred to herein as a micro radar. Specific embodiments of the invention can be used to detect and/or track personnel, vehicle, and/or other targets.

Abstract: An adjustable handle for a power tool is disclosed. The adjustable handle may be rotated about the longitudinal axis of the handle to a position desired by the user and locked into the desired position by a locking member. The adjustable handle may be positioned into one of a plurality of predetermined handle positions.

Abstract: Embodiments pertain to methods of improving the performance of a frequency modulation continuous wave (FMCW) radar system and improving the value of the information provided the FMCW system. In an embodiment, the IF level is monitored while sweeping the frequency of the system through at least a portion of the frequency range of the system and the frequency is set to produce the minimum IF level. Embodiments expedite the adaptation of the comb filter to the signal when the system is turned on. In an embodiment, a method of quickly determining the largest peaks in the RDM is implemented. Embodiments relate to a method for processing a radar signal that classifies two or more targets. An embodiment classifies a human target or other target(s) using amplitude values in time-consecutive range-Doppler maps. An embodiment processes a radar signal for improving the performance of FMCW detection, tracking, and classification algorithms.
