Abstract: An electronic motor drive for powering permanent magnet air core synchronous motors having sinusoidal back emf includes a switchmode power converter coupled to a connection of an input power supply. The power converter converts power from the input power supply with a current-mode control output and regulates current to a variable voltage link that supplies the regulated current to a non-modulating commutation inverter that energizes multi-phase air core armature windings of the air core motor. The motor drive employs 6-step position sensorless commutation exciting only two phase legs at a time controlled through measurement of the back emf. The switchmode power converter includes a low pass inductance and capacitance filter ahead of a power supply of the commutation inverter. The regulated current is switched at a regulation frequency high enough to preclude significant switching-induced harmonic ripple currents to the air core armature windings.

Abstract: A rope dispensing apparatus for rapidly dispensing a continuous rope from a compressed rope cartridge. The apparatus includes a canister for storage of the rope cartridge, a resealable lid with an opening for passing the rope from the cartridge out of the canister through the lid, and a replaceable cutting mechanism for cutting the rope when a desired length has been dispensed. Preferably, the rope cartridge is shrink-wrapped to fit within the canister and keep the rope from unraveling while therein.

Abstract: Systems and methods for aggregating and storing different types of data, and generating interactive user interfaces for analyzing the stored data. In some embodiments, entity data is received for a plurality of entities from one or more data sources, and used to determine attribute values for the entities for one or more given time periods. The plurality of entities may be categorized into one or more entity groups, and aggregate attribute values may be generated based upon the entity groups. A first interactive user interface is generated displaying the one or more entity groups in association with the aggregated attribute values associated with the entity group. In response to a received indication of a user selection of an entity group, a second interactive user interface is generated displaying the one or more entities associated with the selected entity group, each entity displayed in association with the attribute values associated with the entity.

Abstract: Systems and methods for detecting objects and weather in space are disclosed. A system for detecting an object in space and space weather includes at least one spacecraft, at least one radiation source, at least one detector, and a controller. The at least one radiation source and the at least one detector are coupled to the at least one spacecraft. The at least one radiation source is configured to transmit a signal. The at least one detector is configured to detect the signal. The signal may be reflected from an object in space. The controller is coupled to the spacecraft and is in communication with the plurality of detectors. The controller is programmed to calculate either a relative position of the object based or a plasma parameter in a region traversed by the signal based on the detected signal.

Abstract: Some embodiments of the invention provide a computer system for processing an audio track. This system includes at least one DSP for processing the audio track. It also includes an application for editing the audio track. To process audio data in a first interval of the audio track, the application first asks and obtains from the DSP an impulse response parameter related to the DSP's processing of audio data. From the received impulse response parameter, the application identifies a second audio-track interval that is before the first interval. To process audio data in the first interval, the application then directs the DSP to process audio data within the first and second intervals.
