Abstract: Light emitting diodes and display systems are disclosed. In an embodiment a light emitting diode (150) includes a p-n diode (120) including a mesa structure (129) that protrudes from a base structure (131). A reflective metallization (130) laterally surrounds the mesa structure, which also includes a quantum well layer of the p-n diode.

Abstract: A method and structure for stabilizing an array of micro devices is disclosed. A stabilization layer includes an array of stabilization cavities and array of stabilization posts. Each stabilization cavity includes sidewalls surrounding a stabilization post. The array of micro devices is on the array of stabilization posts. Each micro device in the array of micro devices includes a bottom surface that is wider than a corresponding stabilization post directly underneath the bottom surface.

Abstract: An exercise system presents display programming at a rate that is commensurate to a user's exercise rate. The user's exercise rate is monitored and compared to a default exercise rate. When the user's exercise rate is above or below the default exercise rate, the presentation of the display programming is adjusted to maintain a temporal relationship between the user's exercise rate and the display programming. The presentation of the display programming can be adjusted by periodically skipping or pausing frames of the display programming to increase or decrease the duration of the display programming.

Abstract: The present invention discloses a high electron mobility transistor (HEMT) and a manufacturing method thereof. The HEMT device includes: a substrate, a first gallium nitride (GaN) layer; a P-type GaN layer, a second GaN layer, a barrier layer, a gate, a source, and a drain. The first GaN layer is formed on the substrate, and has a stepped contour from a cross-section view. The P-type GaN layer is formed on an upper step surface of the stepped contour, and has a vertical sidewall. The second GaN layer is formed on the P-type GaN layer. The barrier layer is formed on the second GaN layer. two dimensional electron gas regions are formed at junctions between the barrier layer and the first and second GaN layers. The gate is formed on an outer side of the vertical sidewall.

Abstract: A method for achieving fast and efficient measurement of path capacity of a communication network. The method includes the following steps: (a) transmitting a number of probes from a local endpoint to a remote endpoint over a network path and each probe contains at least two outgoing packets and each probe can elicit at least two response packets from the remote endpoint; (b) determining a first minDelay by measuring RTT between the time sending the first probe packet and the time receiving the first response packet; (c) determining a second minDelay by measuring RTT between the time sending the second probe packet and the time receiving the second response packet; and (d) determining a minimum delay difference by subtracting said first minDelay from said second minDelay. The minimum delay difference divided by packet size can be used as a measurement of the network path capacity.
