Abstract: A collection device for debris and animal waste is an apparatus that optimizes airflow to effectively and safely collect debris, preferably pet waste. The apparatus includes a canister, at least one handle assembly, an airflow inlet nozzle, a portable power source, and a fan assembly. The canister houses collected debris and the fan assembly. The at least one handle assembly, the airflow inlet nozzle, and the portable power source are mounted with the canister. The at least one handle assembly allows a user to easily maneuver the canister and the airflow inlet nozzle. The fan assembly suctions debris into a debris chamber of the canister through the airflow inlet nozzle. The portable power source provides the necessary power for the fan assembly to operate. The apparatus further includes an air-permeable collection bag that is housed within the debris chamber to facilitate the removal of collected pet waste within the canister.

Abstract: A canister attachment for leaf blowers/vacuums is an apparatus that attaches to existing yard waste leaf blower/vacuum's to provide a user with a facilitated means to collect solid animal waste or other debris deposited on the ground. The apparatus comprises a suction nozzle assembly, a canister, a suction duct, a support assembly, and a leaf blower/vacuum. The suction nozzle assembly comprises a canister mount and a nozzle. The canister comprises a nozzle mount, a lateral surface, a filter plate, a duct opening, and a first and second chamber. The suction duct comprises a duct canister mount, a channel, and a leaf blower/vacuum mount. The configuration of these components provides the user with a mobile accessory that utilizes the suction from existing conventional leaf blowers/vacuums to siphon animal waste through the nozzle and into the canister. Furthermore, the apparatus provides an exhaust catch to prevent accidental discharge through the leaf blower/vacuum.

Abstract: Methods and devices for determining the position and/or angular orientation of a rotating shaft. Exemplary features include a sensor module and a position determination module. Sensor module may include a plurality of Hall Effect devices (HEDs) arranged at a specified angular separation to produce a signal in response to rotation of the shaft. Position module may be responsive to sensor module to produce a converted signal, determine an error term, and produce a position estimate. Converted signal may be produced by processing the HED signals into sinusoidal reference signals having offset scale and amplitude scale factors. Error term may be determined by processing the converted signals to produce an estimated position signal. Position estimate may be produced by processing the error term. Refined position measurement may be achieved by iterative elimination of regressive differences between position estimates with minimization of absolute magnitude of error term.
