Abstract: Systems and methods for generating object references with selectable scopes are provided. The systems and methods perform operations including calling, by a first entity, a reference generator function using one or more arguments associated with a database object that the first entity is authorized to access according to a first set of access privileges, the one or more arguments comprising a scope definition that defines persistence of a reference. The operations include obtaining, from the reference generator function, a reference to the database object, the reference persisting according to the scope definition. The operations include passing the reference to a second entity to enable the second entity to perform one or more database operations on the database object according to a second set of access privileges derived from the first set of access privileges.

Abstract: A stator of a resolver includes a body having a pole, a connector interface disposed in a portion of the body and including a terminal having a wire termination at a termination end, and a wire disposed around the pole and extending to the termination end of the terminal. The terminal has a bent section at the termination end that is bent to a bending angle greater than 0° and less than or equal to 90° with respect to a main section of the terminal. The wire is electrically and mechanically connected with the terminal at the wire termination. The bent section of the terminal forms a slackened portion of the wire adjacent to the wire termination.

Abstract: A resolver includes a stator having a stator body formed of a first plastic material and a cover covering a side of the stator. The cover has a cover body formed of a second plastic material. The first plastic material of the stator body is attached to the second plastic material of the cover body by a plastic weld.

Abstract: A multichannel stethographic device includes a plurality of individual stethoscopes that may be embedded in a foam pad or surface mounted on a thin flexible substrate. Additional stethoscopes for the heart and thorax may also be utilized. The system may include a signal conditioning circuit, wireless DAQ module, and software (algorithms). The systems may be configured to identify and diagnose various disease conditions such as pneumonia, chronic obstructive pulmonary disease (COPD), asthma, congestive heart failure (CHF), interstitial pulmonary fibrosis (IPF), and vocal cord dysfunction (VCD).
