Abstract: A brushless direct-current motor is provided includes an inner stator and an outer rotor. The rotor includes a rotor core disposed around the stator, an inner annular member mounted on a rotor shaft, and a plurality of radial blades extending angularly from the rotor core to the inner annular member forming a fan. A first end cap is provided including a radial back plate proximate the fan and a center opening in the radial back plate through which the rotor shaft extends. A second end cap is provided including a main body disposed adjacent the stator opposite the fan. The radial back plate of the first end cap includes at least one sloped surface forming at least one air gap such that the airflow generated by the fan is centrifugally guided within the first end cap by the sloped surface and caused to exit through the air gap.

Abstract: In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

Abstract: Instruments and surgical techniques may be used to correct a bone deformity, such as a bunion in which a metatarsal is misaligned with respect to a medial cuneiform. In some examples, a bone cutting guide is utilized to cut an end of the metatarsal and/or an end of the medial cuneiform to facilitate realignment of the bones. The cutting guide can have a pivotable cut guide surface along which a cutting instrument is translated to provide a precise bone cut. In some applications, after suitably preparing and aligning the bones, the bones are compressed together using a fixation pin. The fixation pin can be driven through one of the bones, into the second bone, and then further driven to compress the bones together.

Abstract: A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A system and method of verifying the identity of a user or registrant. The user or registrant provides identification information and registration information. The identification information may be a visual representation of an identifying item associated with location information. In some embodiments, the identification information may be a visual representation of a government issued identity. An identification module verifies the identification information and compares the verified identification information to the registration information.

Abstract: A pallet that is configured and designed to support a load of material and rest alternatively on a flat surface on a roof so as to straddle the peak or ridge of a roof. The pallets can be loaded with materials such as roofing shingles, delivered to a work site on a truck bed and lifted up and positioned on the peak or ridge of a roof without having to unload the materials from the pallets.

Abstract: A fuel cell temperature-measuring system includes a coolant source that provides coolant at a total coolant flow rate and an initial coolant temperature. A flow field plate defines peripheral flow channels and active area flow channels through which coolant flows. The flow field plate is adapted to be positioned in a fuel cell stack between individual fuel cells. A total coolant flow provided to the common input divides into a bypass flow that flows through the peripheral flow channels and an active area flow that flows through the active area flow channels. The bypass flow combines with the active area flow to emerge from the common output with an output coolant temperature. The fuel cell temperature-measuring system includes a temperature sensor that measures the output coolant temperature from the common output. Finally, a temperature estimator estimates an active area coolant temperature from the output coolant temperature.

Abstract: A fuel cell voltage recovery system includes a fuel cell stack having a fuel cell stack voltage between fuel cell stack terminals which is at a first voltage during normal fuel cell operation. The system also includes a high voltage electrical system operating at a first DC operating voltage that is generally higher than the first voltage of the fuel cell stack. A boost converter in electrical connection with the fuel cell stack and the high voltage electrical system operates in a normal control mode to transfer electrical power from the fuel cell stack to the high voltage electrical system through regulation and control of average stack output current (boost input current) during normal fuel cell operation. The boost converter can also operate in a voltage control mode to lower the fuel cell stack voltage to a second voltage that is lower than the first voltage. A FCS controller controls the operation of the boost converter.
