Systems, apparatuses, and methods for network-managed direct device to device communications are provided. The three phase legs are interconnected in a neutral point by forming a wye-connection. During an IHS cure and reflow process the foaming material will expand and fill the IHS cavity and the foam’s shape conforms to the various surface features present, encapsulating a thermal interface material material, and increasing contact area of the foam sealant. Performance improvements and reduced costs of disk drives can thereby be attained. Herein, the plurality of dots is formed of a main droplet which flies at the start; and a droplet formed by coalescing, after capturing, a plurality of satellite droplets which is discharged as a result of the discharge action of the main droplet, before the satellite droplets have been shot onto the recording medium. The lens has a compact volume, and provides stable imaging performance and good image quality.
