`
`SMART DEVICE INCLUDING BOMETRIC
`SENSOR
`
`BACKGROUND
`
`0001 1. Field
`0002 The present disclosure is directed to a smart device
`including a biometric sensor.
`0003 2. Introduction
`0004 Presently, Smart watches and smart glasses provide
`information and an interface for users beyond traditional
`watches and glasses. For example, a Smart watch wirelessly
`pairs with a cellular phone and provides a user interface for
`the cellular phone. A Smart watch includes a display that
`displays time information and cellular phone information
`including text message information and incoming call infor
`mation. The Smart watch also includes a touch screen that
`receives user input for both the Smart watch and a paired
`cellular phone and includes a microphone for Voice commu
`nication.
`0005. Unfortunately, due to the small real estate of smart
`watches and Smart glasses, they do not provide all of the
`features desired by users, such as effective biometric sensor
`features while maintaining a desirably small size. Thus, there
`is a need for a Smart device including an effective biometric
`SSO.

`0024 FIG.3 is an example a user side exploded view of an
`apparatus 300, such as a user side exploded view of a portion
`of the apparatus 100, according to a possible embodiment.
`The apparatus 300 can include the lens 140, the lens opaque
`section 142, and the lens light transmissive section 144. The
`apparatus 300 can additionally include the light emitter 120,
`the light detector 130, and additional light emitters 322,324.
`and 326. According to a possible embodiment, the light emit
`ter 120 can be a red light emitter, the light emitter 322 can be
`an infrared light emitter, and the light emitters 324 and 326
`can be green light emitters. The light emitters 120,322,324.
`and 326 can also be other variations of light emitters as
`discussed above.
`0025. The apparatus 300 can also include the housing 210.
`The housing 210 can include a device aperture 350 on a user
`side of the apparatus 300 from the light emitters 120, 322.

`(0028 FIG. 5 is an example illustration of the lens 140
`according to another possible embodiment. The lens 140 can
`include the opaque section 142. The lens 140 can also include
`light transmissive sections 144, 145, and 422. This embodi
`ment illustrates a possible variation of light transmissive sec
`tions. Other designs of light transmissive sections can also be
`used depending on aesthetics and functionality of the lens
`140.
`0029 Embodiments can provide a lens and grommet that
`can cover up components of an apparatus, allow for a seam
`less design, and allow for apparatus components to be hidden.
`Embodiments can also provide for a light sealing grommet
`and artwork on a lens including light transmissive sections to
`focus emitted and received light.
`0030 Operations of this disclosure can be implemented on

`also be implemented on a general purpose or special purpose
`computer, a programmed microprocessor or microcontroller
`and peripheral integrated circuit elements, an integrated cir
`cuit, a hardware electronic or logic circuit Such as a discrete
`element circuit, a programmable logic device, or the like. In
`general, any device on which resides a finite state machine
`capable of implementing the flowcharts shown in the figures
`may be used to implement the processor functions of this
`disclosure.
`0031 While this disclosure has been described with spe
`cific embodiments thereof, it is evident that many alterna
`tives, modifications, and variations will be apparent to those
`skilled in the art. For example, various components of the
`embodiments may be interchanged, added, or Substituted in
