  • Publication number: 20240145927
    Abstract: A device having a dual-inverted L antenna (DILA) and an LC tank circuit configured to improve specific absorption rate (SAR) hotspots. The SAR hotspots are split between a first aperture defined between the DILA and a daughter printed circuit board (PCB), and the second aperture defined between the daughter PCB and a battery casing. A main PCB is coupled to battery by a flexible circuit board (FCB). The DILA is configured to radiate RF energy at a first frequency, and the LC tank circuit is configured to radiate RF energy at a second frequency to improve bandwidth.

  • Patent number: 10379911
    Abstract: The systems described herein are configured to reduce the number of resource policies created and stored on a cluster for provisioning and/or managing virtual computing instances (VCIs) utilization of one or more resources. An open-ended VCI policy including at least one open-ended rule having an undefined value and a resource is selected. A set of valid values compatible with a selected resource corresponding to each open-ended rule is presented to the user. The user selects a valid value for each open-ended rule from the set of valid values via a user interface (UI). The selected valid values are assigned to each open-ended rule to create a complete VCI open-ended policy. The complete VCI open-ended policy is applied to provision one or more VCIs. The same open-ended VCI policy may be applied to provision different VCIs by assigning a different set of user selected valid values.

  • Patent number: 9872094
    Abstract: This application relates to an audio assembly that includes both a speaker assembly and a microphone. By mounting both the microphone and the speaker assembly to a unitary audio bracket, space savings can be achieved over a configuration that relies on separate brackets for each component. In some embodiments, an acoustic mesh can be embedded within the audio bracket and extending across an audio channel defined by the audio bracket. The microphone can be aligned with an opening in the audio bracket by an alignment clip that is coupled with the microphone. The alignment clip helps to achieve alignment of a sensor opening of the microphone with a channel defined by the audio bracket.

  • Patent number: 4065393
    Abstract: A conical centrifuge with continuous action, comprising a cylindrical housing, ending with a cone and a connection in its bottom end for the removal of the solid phase. Inside this cone there is fixed coaxially a cylinder, ending with a cone and a connection for the removal of the liquid phase, and over said cylinder there is disposed a conical rotor attached to a shaft, supported in a bearing box and connected by means of a belt drive to an electric motor, which is fastened to the cover of the housing. Concentrically with the bearing box there is provided a vertical pipe, in which there ends a connection, and this vertical pipe is connected to the bearing box by means of vertical blades, which are inclined with respect to the radius and to their outer ends there are fastened helical-shaped blades.
