The down converter material may comprise a polycrystalline ceramic plate of a phosphor material. A method of manufacturing a light source comprises: measuring a baseline color point distribution of a baseline light source, and a primary down converter material in the absence of any laser-modified down converter material; preparing a baseline color point distribution graph; identifying one or more sections of the primary down converter material whose corresponding LEDs contribute to deviating from a tuned color point distribution; and applying a roughening laser treatment to prepare one or more sections of roughened down converter material, and thereby prepare a light source having the tuned color point distribution.

Abstract: A phosphor layer is attached to an LED with increased precision. In particular, a phosphor ceramic is attached to an LED with glue. During the attachment process, the glue must be hardened and/or cured. The phosphor ceramic includes a hood that contains the glue in the hood as it hardens and/or is cured in order that the phosphor ceramic is properly aligned on the LED. The hood also improves the light extraction by capturing the light emitted from the sides of the LED.

Abstract: A light emitting device comprises at least two semiconductor LEDs arranged in an array with each semiconductor LED comprising a light emitting surface with boundaries defined by a perimeter, a continuous layer comprising a first surface through which light is emitted from the light emitting device during operation and an oppositely positioned second surface disposed on or adjacent to the array and extending over the light emitting surfaces of the semiconductor LEDs, and a plurality of optical isolation structures arranged in the continuous layer in a discontinuous manner along the perimeters of the light emitting surfaces between adjacent LEDs in the array.

Abstract: A light-emitting diode (LED) can have a light-emitting surface that can emit emitted light. A filter, disposed on the light-emitting surface, can be at least partially transmissive in a first area and at least partially reflective in a second area. The first area can direct at least some of the emitted light through the filter to form shaped light that extends over an area corresponding to a shape of a static light pattern. The second area can reflect at least some of the emitted light into the LED through the light-emitting surface. A lens can bring the shaped light to a focus that has the shape of the static light pattern. To increase a contrast of the focus, an absorber, disposed on the second area of the filter, can absorb emitted light that is transmitted through the second area of the filter.

Abstract: Methods, systems and apparatus for conducting mobile device person-to-person voice payments. An embodiment includes a mobile device processor of a mobile device detecting a first key entry by a sender during a mobile telephone call, muting the call, prompting the sender to enter persons-to-person (P2P) security data and a payment amount, and detecting a second key entry. The mobile device processor then prompts the sender to provide voice data associated with a password, detects a third key entry, and then transmits a P2P payment request including the P2P security data, the payment amount, the voice data, sender account data, and a recipient mobile telephone number, to a mobile person-to-person (P2P) computer. The mobile device processor then unmutes the mobile telephone call and receives a P2P payment message from the mobile P2P computer.

Abstract: A mobile device includes a pedometer function that calculates an estimated distance based on sensor measurements. The sensor measurements are used to determine a step frequency of the user, which is used to estimate the distance traveled by the user. To correct for the unique step frequency of the user, a calibration factor is calculated that can be multiplied by the estimated distance to improve the accuracy of the distance estimate. New calibration factors resulting from calibration trials are assigned to step frequency bands. An average calibration factor is calculated for each frequency band. The average calibration factors of the bands are updated to ensure that the average calibration factor of any given band is greater than or equal to the average calibration factors in all lower bands.

Abstract: A method of determining a discount amount for an electronic commerce transaction can include determining, by a processor, whether a member of a financial institution has posted a review for an electronic commerce purchase within a preset threshold amount of time from a time when the member received a purchased item. Upon identifying the time at which the member posted the review, the processor can determine an eligible time period based on the preset threshold amount of time and the identified posting time. The processor can determine the number of occurrences of different eligible discount earning events by tracking, for the eligible time period, activities related to the review performed on one or more social media platforms. The processor can determine a discount amount based on the determined discount earning events and transmit an instruction to credit a financial account with a credit amount corresponding to the discount amount.
