Abstract: An installer for installing a software program on a computing device can be executed. The installer can perform a set of dependency checks before installing the software program. The set of dependency checks can include the validation of a pre-requisites associated with the proper execution of the software program. The pre-requisites can be a portion of a dependency content. The content can be a checklist. Before the software program is installed on the device and responsive to executing the installer, the installer can update dependency content using a custom dependency checklist. The updating of the dependency content can be performed without updating code of the software program to be installed on the device. The execution of the installer can continue using the updated dependency content for performing the set of dependency checks responsive to automatically updating the dependency content.

Abstract: There is provided an aircraft engine anti-icing (EAI) barrier assembly. The aircraft EAI barrier assembly has a slip joint subassembly having a forward end and an aft end. The forward end is configured for fixed attachment at a forward bulkhead of an engine of an aircraft, and an aft end with a sliding joint. The aircraft EAI barrier assembly has a barrier subassembly attached through an aft bulkhead and has two mount pads configured for joined sealed attachment around the aft end of the slip joint subassembly to form a barrier to an engine inlet of the engine.

Abstract: The present disclosure is directed, at least in part, to a self ligating orthodontic bracket having a rotatable member for securing an archwire within a slot of the bracket. Embodiments of the orthodontic bracket disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot.

Abstract: A coring extender for a coring tool is provided. The coring tool is deployable by a downhole tool into a wellbore. The coring extender includes a housing operatively connectable to the downhole tool, a mandrel, and seals. The housing has fluid chambers therein. The mandrel is positionable in the housing, and includes a locking tube operatively connectable to the housing and a coupling tube operatively connectable to the coring tool. The coupling tube is adjustably positionable relative to the locking tube such that a length of the mandrel is adjustably defined therebetween. The coupling tube has an outer surface slidably positionable along an inner surface of the housing. Seals are positionable between the mandrel and the housing to define a fluid pocket to isolate the fluid therebetween as the coupling tube moves along the housing whereby the fluid permitted to flow about the fluid pocket to balance between the fluid chambers.

Abstract: A power supply system includes an Offline Total Power Management Integrated Circuit (OTPMIC). The OTPMIC controls a Power Factor Correction (PFC) converter, a main AC/DC converter, and a standby AC/DC converter. A PFC Autodetect circuit in the OTPMIC monitors current flow in the PFC converter. If a high power condition is detected, then the PFC Autodetect circuit enables the PFC converter. The high power condition may be a voltage drop across a current sense resistor of a predetermined voltage for a predetermined time, within one half period of the incoming AC supply voltage. If a low power condition is detected, then the PFC Autodetect circuit disables the PFC converter. The PFC Autodetect circuit stores an IMON value that determines the predetermined voltage, and a TMON value that determines the predetermined time. The IMON and TMON values are loaded into the Autodetect circuit across an optocoupler link of the standby converter.
