A multi-sensor edge computing system can have at least a sensor assembly connected to an edge computing device and a downstream host. The sensor assembly may have a first sensor and a second sensor with the respective sensors being different. The edge computing device can be configured to identify a false reading of the first sensor in response to data captured by the second sensor.

A lubricant is applied to swage contact surfaces in a disk drive of the type including a suspension arm connected to an actuator arm by a swaging process. A preferred thin film lubricant may be applied to the contact surfaces by immersion and draining, immersion and raising the part out of the solution, localized spraying, or various deposition processes. Application of the lubricant reduces chipping during de-swaging, particularly with nickel plated metal components. Application of the lubricant has also shown to improve gram load uniformity, reduce adverse distortion to the actuator assembly and reduces torque out retention values. Improved gram load uniformity enhances overall disk drive functioning, reduced distortion preserves intended attitude and flatness of the actions for assembly and reduced torque out retention values improves reworkability of the disk drive.

Method of reducing torque out retention values in de-swaging of actuator of disk drive

A method is provided for assembling an actuator assembly of a disk drive. The method includes providing an actuator arm, providing a suspension arm, fixing a swage plate to the suspension arm, the swage plate including a swage boss extending therefrom, depositing a film lubricant upon at least an outer surface of the swage boss, and attaching the suspension arm to the actuator arm by swaging. A method is also provided for reducing torque out retention values between the actuator arm and the suspension arm when the actuator arm and suspension arm must be separated in a subsequent de-swaging process. This method includes providing an outer surface of the swage boss, and applying a lubricant film coating to the outer surface of the swage boss. A preferred thin film lubricant may be applied by emersion and draining, localized spraying, or various deposition processes. Application of the lubricant has also shown to improve gram load uniformity and to reduce adverse distortion to the actuator assembly which otherwise occurs during swaging.

A method is provided for protecting a head element of a computer disk drive during rework operations by applying thioropolymeric protective coating or film to the head element after the disk drive has been opened. Application of the protective coating is preferably performed utilizing a solvent-mediated deposition process. Further aspects of the invention include the application of the protective coating to the head element prior to storage of the head element or prior to shipping the head element in order to facilitate rework of the head element or other components of the disassembled disk drive.

A material delivery system is disclosed which is particularly useful for filtered environments, such as clean rooms, minienvironments, or the like. In one embodiment, the material delivery system is disposed below a work area in a clean room-like environment to store parts to be used at the work area. In another embodiment, the material delivery system includes a material delivery elevator for transporting parts to a desired elevational level. In yet another embodiment, the material delivery system includes a cover which is detachably interconnected with a body to define an enclosed material storage area. An assembly is provided to lock the cover down onto the body with a gasket therebetween to appropriately seal this interconnection. This same assembly lifts the cover up and away from the body so as to not damage this gasket. Finally, this same assembly also allows the cover to be rolled off of the body without exposing the gasket to any shear-like forces so as to further reduce the potential for damage to the gasket during removal of the cover from the body.

An improved arm for an electronic servo mechanism is described which includes a plurality of glue pockets formed within it for bonding a coil assembly to the arm. A method for bonding the coil assembly to the arm is described in which a predetermined amount of glue is placed into each of the glue pockets.
