`
`[0016] The apparatus 100 can includea light detector 130
`that can detect light 135 reflected from the wrist of the user
`from thefirst light emitter 120. The light detector 130 can be
`a photodetector, a light sensor, or any other light detector. The
`light emitter 120 and light detector 130 can be used for pho-
`toplethysmography, pulse oximetry, and other biometric
`sensing.
`[0017] The apparatus 100 can include a lens 140 coupled to
`a user side of the wrist worn device 110 external to the light
`emitter 120 and the light detector 130. The lens 140 can
`include an opaquesection 142, a first light transmissive sec-
`tion 144. Thefirst light transmissive section 144 can transmit
`the light 125 emitted from the light emitter 120 to a wrist of
`the user. The apparatus 100 can also include a second light
`transmissive section 145 separate from the first light trans-
`missive section 144. The second light transmissive section
`145 can transmitlight 135 reflected from the wrist of the user
`to the light detector 130. When multiple light emitters are
`used, the lens 140 can include multiple separate light trans-
`missive sections for each light emitter and for the detector.
`For example, each light transmissive section 144 and 145 can
`be an aperture in the opaque section 142. Furthermore, if
`multiple light emitters are used, the light transmissive section
`145 for the detector 130 can be located in between light
`transmissive sections for each of the two or more light emit-
`ters. The light transmissive sections 144, 145 can be fully
`transmissive or can be partially transmissive to only transmit
`light of a desired wavelength through the lens 140.
`[0018] The lens 140 can have an opaque layer 142 includ-
`ing the light transmissive sections 144 and 145. The lens 140
`can also be an opaque lens including the light transmissive
`sections 144 and 145as apertures in the lens. The lens 140 can
`be madeof metal, plastic, glass, thermoplastic, such as Poly
`(methyl methacrylate) (PMMA), or any other useful material.
`The lens opaque section 142 can be a screen printed layer, a
`spray painted layer, or other opaque layer. The lens 140 can
`further include a coated layer, such as a clear coat layer, that
`provides protection, durability, scratch resistance, and other
`protection ona userside ofthe lens 140. The coated layer can
`be part of the opaque layer 142 or can be separate from the
`opaque layer 142. The lens 140 can also provide the opaque
`section 142 by being opaque andthe transmissive sections
`144 and 145 can be etched, molded, drilled, laser cut, or
`otherwise formed to provide transmissive sections 144 and
`145 in the lens 140. The opaque section 142 can conceal
`portions of the apparatus 100 from the user to hide internal
`components of the apparatus 100 from view. The opaque
`section 142 can include decorations and the decorations can
`
`incorporate the light transmissive sections 144 and 145 into
`the decorations to obscure or highlight the light transmissive
`sections 144 and 145.
`
`FIG. 2 is an example block diagram of the apparatus
`[0019]

`ler 220. The light detector 130 can send a detector signalto the
`controller 220, where the detector signal can be based on the
`detected light 135. The housing 210 can be a housing that
`houses the componentsofthe apparatus 100. The housing 210

`
`radio frequency transmitter, a near filed communication
`transmitter, a wireless local area network transmitter, a cel-
`lular network transmitter, an infrared transmitter, and/or any
`other wireless transmitter. The transceiver 250 can transmit a
`
`wireless communication signal based on the detector signal
`generated by the light detector 130. The wireless communi-
`cation signal can be a wireless near field communication
`signal, a wireless local area network communication signal,
`or a cellular communication signal. The transceiver 250 can
`also transmit other wireless communication signals, such as

`FIG. 4 is an example illustration of the lens 140
`according to a possible embodiment. The lens 140 can
`include the opaque section 142. The lens 140 can also include
`a plurality of light transmissive sections 144, 145, 410, 412,
`414, 423, and 424. The light transmissive sections 144, 145,
`410, 412, 414, 423, and 424 can be separate and distinct from
`each other in the opaque section 142. The light transmissive
`sections 144, 410, 412, 414, 423, and 424 can transmit light
`from the light emitters 120, 322, 324, 326 of FIG. 3 and other
`light emitters. The light transmissive section 145 can transmit
`light reflected from a userto the light detector 130 of FIG.3.
`Variations of light transmissive sections or apertures can be
`used. For example, the light transmissive sections 423 and
`424 may only be included for aesthetic purposes, such as to
`provide a pleasing design of light transmissive sections on the
`lens 140. Also, the light transmissive sections 423 and 424
`can be apertures in the lens 140 to provide sound or other
`functions.

`
`[0025] The apparatus 300 can also includethe 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,
`324, and 326 andthe light detector 130. The apparatus 300
`can include a grommet 330 within the device aperture 350.
`The grommet 330 can include a first grommet aperture 340
`configured to emitlight from the light emitter 120 through the

`include a second grommetaperture 348 configuredto receive
`light reflected from the light emitter 120 through the light
`transmissive section 144to the light detector 130. The grom-
`met 330 can also include additional grommet apertures 344
`and 346 for additional
`light emitters 324 and 326. For
`example, the light emitters 324 and 326 can be green light
`emitters located on opposite sides of the light detector 130.
`Accordingly, the grommetapertures 344 and 346 forthe light
`emitters 324 and 326 can be located on opposite sides of the
`grommetaperture 348for the light detector 130. Other com-

`tor 130, and grommetaperture 340, 342, 344, 346, and 348
`locations can also be used. The grommetapertures 340, 342,
`344, 346, and 348 and/or separate light transmissive sections
`144 of the lens 140 can prevent crosstalk between light emit-
`ters 120, 322, 324, and 326 and can preventcrosstalk between
`the light emitters 120, 322, 324, and 326 and the light detector
`130.

`[0026] The apparatus 300 can include a charging coil 310
`surroundingthe light emitters 120, 322, 324, and 326 and the
`light detector 130. The light emitters 120, 322, 324, and 326
`and the light detector 130 can be placed in the middle of the
`charging coil 310 to reduce the thickness ofthe apparatus 300.
`The charging coil 310 can charge the power supply 280

`[0030] Operations ofthis disclosure can be implemented on
`a programmedprocessor. However, the controller 220 may
`also be implemented on a general purpose or special purpose
`computer, a programmed microprocessor or microcontroller
`and peripheral integrated circuit elements, an integrated cir-

`
`[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
`the other embodiments. Also, all of the elements of each
`figure are not necessary for operation of the disclosed
`embodiments. For example, one of ordinary skill in the art of
`the disclosed embodiments would be enabled to make and use
`
`the teachings of the disclosure by simply employingthe ele-
`ments of the independentclaims. Accordingly, embodiments
`ofthe disclosure as set forth herein are intendedto be illus-
`
`trative, not limiting. Various changes may be made without
`departing from the spirit and scope of the disclosure.

`order between such entities or actions. The phrase “at least
`one of”followedbya list is defined to mean one, some,orall,
`but not necessarily all of, the elements in the list. The terms
`“comprises,” “comprising,”or any other variation thereof, are
`intended to cover a non-exclusive inclusion, such that a pro-
`cess, method, article, or apparatus that comprises a list of
`elements does not include only those elements but may
`include other elements not expressly listed or inherent to such

`or more. The terms “including,” “having,” and the like, as
`used herein, are defined as “comprising.” Furthermore, the
`background section is written as the inventor’s own under-
