Abstract: In formation of a quantum dot structure in a light emitting layer, a matrix region (an n-type conductive layer and matrix layers) is formed on a growth underlying layer of AlN whose abundance ratio of Al is higher (or whose lattice constant is smaller) than that in the matrix region by an MBE technique, thereby to realize conditions where compression stress is caused in an in-plane direction perpendicular to the direction of growth of the matrix region, and then to form island crystals by self-organization in the presence of this compression stress. The compression stress inhibits an increase in lattice constant caused by the reduced abundance ratio of Al in the matrix region, i.e., to compensate for a difference in lattice constant between the island crystals and the matrix region. The compression stress functions to enlarge compositional limits for formation of the island crystals by self-organization to the Ga-rich side.

Abstract: The invention is directed towards a method and transmission attempt determining device for adjusting the targeted number of transmission attempts in uplink communications between mobile stations and a cell in a wireless network handled by a cell handling device. According to the invention measurement data (RC) of radio conditions and service requirement data (SR) of the uplinks for mobile stations are obtained (36, 38, 40). Based on this data a determination (42) is made if the targeted number of transmission attempts should be adjusted. If a change should be made (42) an increase or a decrease is then determined (44) and the targeted number of transmission attempts are adjusted in the selected direction (46).

Abstract: A device for counting the number of rotations of an object in a system, in which a storage means carries counting data designed to represent the number of rotations counted. The counting data is used for conditionally resetting the storage means if and only if two separate conditions are fulfilled, where at least of one of the conditions is the reception of information from an external device, thereby insuring that the counting data represents the number of rotations counted from a predetermined time.

Abstract: Data packet processing is described. A set of first data packets is accessed. A number of the first data packets are identified as candidate data packets to be potentially transmitted over a network to a receiver. The number of candidate data packets is then reduced so that a number of second data packets comprising error correction information for one or more of the first data packets can be increased.

Abstract: A method of authenticating the identity of an item bearing or associated with a printed security marker, the method comprising: a. printing the security marker with a pattern that encodes at least one of a unique product identifier, a batch identifier, and positional information about a portion of the marker; b. scanning and storing an image of the security marker as printed, said image being taken at sufficiently high resolution to capture artifacts of the printing process; and authentication steps comprising: c. imaging a portion of the marker at sufficiently high resolution to capture the artifacts, and d. querying a data store by providing the image of the portion of the marker or a compressed or parameterized version of the image and data derived from the pattern.

Abstract: A method for localizing a tag includes activating an antenna to transmit an RF signal and monitoring for a responsive signal transmitted by the tag. The signal range of the RF signal transmitted by the antenna may be altered if a responsive signal from the tag is not received. The method further includes detecting the responsive signal transmitted by the tag after the tag receives the RF signal transmitted at the altered signal range.
