20120091163 | GRAVITY-FED DISPENSER - Systems and methods related to dispensing food (e.g., fruit) or other items in a “first-in, first-out” manner are discussed. The system can include a base having one or more cavities therein and a plurality of chutes configured to align within a subset of the cavities. Each of the chutes can include an inlet that can provide access to an open interior for storage of items, and the plurality of chutes can dispense the plurality of items in a “first-in first out” manner. An ice chest capable of cooling the plurality of chutes can be included, as can a drip tray or other mechanism for separating the fruit from its juices to prolong its useful lifespan. | 04-19-2012 |

20140312811 | POSITION SENSORLESS OPEN LOOP CONTROL FOR MOTOR DRIVES WITH OUTPUT FILTER AND TRANSFORMER - A power converter, control apparatus and methods are presented for driving a permanent magnet motor or other load through a sine wave filter and a transformer, in which inverter output current is controlled using a current-frequency relationship to convert a desired frequency or speed value to a current setpoint, and the inverter output current is regulated to the current setpoint using a control algorithm with a bandwidth below the resonant frequency of the sine wave filter. | 10-23-2014 |
20140320056 | METHODS AND APPARATUS FOR ACTIVE FRONT END FILTER CAPACITOR DEGRADATION DETECTION - Apparatus and methods are provided for detecting degradation of delta-connected filter capacitors in an active front end (AFE) power converter, in which delta circuit capacitor leg currents are calculated based on measured branch circuit currents, and filter capacitor impedance values are computed based on the calculated leg currents as well as measured line-to-line voltages and corresponding phase angles for comparison with one or more thresholds to selectively detect degradation of the filter capacitors. Further apparatus and methods are provided for detecting degradation of Y-connected filter capacitors by computation of fundamental frequency RMS impedance values as ratios of RMS capacitor voltages and RMS circuit branch currents, and comparison of the calculated RMS impedance values with one or more thresholds. | 10-30-2014 |
20140368143 | METHOD AND APPARATUS FOR OVERVOLTAGE PROTECTION AND REVERSE MOTOR SPEED CONTROL FOR MOTOR DRIVE POWER LOSS EVENTS - Apparatus and methods are presented for mitigating overvoltages and limiting reverse motor speeds for motor drive power loss events, in which a first power dissipation circuit is enabled at the motor drive output to limit reverse rotation of a driven motor load when motor drive power is lost, and a second power dissipation circuit in a DC bus circuit is used to mitigate over voltages following restoration of motor drive power. | 12-18-2014 |
