Abstract: The invention provides an optical sensor package. The optical sensor package includes: a printed circuit board (PCB); a sensor disposed on the PCB; a glass cover disposed directly on the sensor; and an aperture disposed on the PCB comprised of a solid perimeter surrounding the sensor and a ceiling having a cut-out section above the glass cover. The cut-out section of the ceiling is smaller in area than the glass cover. The part of the aperture ceiling which overhangs the glass cover is thicker than the remaining part. The optical sensor package further includes an LED die disposed on the PCB, and Kapton tape placed over the ceiling of the aperture.

Abstract: A target detecting device includes: an optical scanner including a mirror; and a casing. The target detecting device further includes a light shielding portion configured to partition the casing into a light projecting space through which projected light travels and a light receiving space through which reflected light travels and configured to block light. The mirror has a first reflecting region which reflects the projected light and a second reflecting region which reflects the reflected light, the first reflecting region and the second reflecting region being located in an identical reflecting surface. The light shielding portion includes: a movable light shielding portion provided on the mirror so as to separate the first reflecting region and the second reflecting region and configured to be movable in conjunction with the mirror; and a fixed light shielding portion fixed to the casing so as to surround the movable light shielding portion.

Abstract: A light converting optical system employing a planar light trapping optical structure illuminated by a monochromatic light source. The light trapping optical structure includes a photoresponsive layer including semiconductor quantum dots. The photoresponsive layer is configured at a relatively low thickness and located between opposing broad-area surfaces that confine and redistribute light within the structure and cause multiple transverse propagation of unabsorbed light through the photoresponsive layer to enhance absorption. The light trapping optical structure further incorporates various microstructured surfaces including light-distributing to surface relief features such as linear microlenses, prismatic surface relief features and/or linear grooves.

Abstract: The various embodiments described herein include methods, devices, and systems for fabricating and operating photodetector circuitry. In one aspect, a photon detector system includes: (1) a first superconducting wire having a first threshold superconducting current; (2) a second superconducting wire having a second threshold superconducting current; (3) a resistor coupled to the first wire and the second wire; (4) current source(s) coupled to the first wire and configured to supply a current that is below the second threshold current; and (3) a second circuit coupled to the second wire. In response to receiving light at the first wire, the first wire transitions from a superconducting state to a non-superconducting state. In response to receiving light at the second wire while the first wire is in the non-superconducting state, the second wire transitions to a non-superconducting state, redirecting the first current to the second circuit.

Abstract: Described herein are systems and methods for mounting optical sensors in physiological monitoring devices worn by a user to sense, measure, and/or display physiological information. Optical sensors may be mounted in the rear face of the device, emit light proximate a targeted area of a user's body, and detect light reflected from the targeted area. The optical sensor may be mounted in a housing or caseback such that at least a portion of the optical sensor protrudes a distance from at least a portion of the housing. The protrusion distance may be adjustable such that a user may achieve a customized fit of the wearable device. Adjustment of the protrusion distance may also result in a customized level of contact and/or pressure between the optical sensor and the targeted area which may, in turn, result in more reliable and accurate sensing of physiological information.

Abstract: A system for transporting high luminous intensity light from at least one luminaire to a destination area is disclosed. The system may include a light guide that carries light from the luminaire to a plurality of sensors located on a Printed Circuit Board (PCB). The PCB may be attachable anywhere the luminaire is located. While collecting light rays originating from the luminaire and delivering them to the light sensors, the light guide may perform a plurality of operations to modify the characteristics of the collected light rays. The plurality of operations performed by the light guide on the light rays may support the accuracy and longevity of the light sensors on the PCB. Further, the light guide allows the sensor subsystem to be proximal to or distant from the luminaire.

Abstract: A light receiver capable of detecting the intensity of light in a certain wavelength range is provided. The light receiver includes a first light receiving element (PD1) and a second light receiving element (PD2) that have an identical spectral sensitivity characteristic, and a UV cut filter (11). Light that has passed through the UV cut filter (11) enters the first light receiving element (PD1). A subtractor is provided that calculates a difference between a photocurrent of the first light receiving element (PD1) and a photocurrent of the second light receiving element (PD2).

Abstract: An integrated optical tap monitor takes the form of a highly-reflective outer coating disposed over the active region of an associated photodetector. The coating is of a material that allows for a majority of the impinging optical signal to be re-directed into an output path, while passing a small portion of the signal into the photodetector's active region for monitoring purposes. The integrated configuration is small enough to be housed within a standard TO can, and additional optical components (filters, attenuators, etc.) may be co-located with the integrated tap monitor. By virtue of incorporating the monitoring function with a reflective surface, the integrated tap monitor may be substituted for a turning mirror at any place along a signal path and provide the benefit of power monitoring while also performing signal re-direction.
