Patent number: 11740394Abstract: An optical power prism that may be used in folded lens systems that consists of a glass prism and a glass lens attached to a surface of the prism using a thin layer of optical glue or by optical contact. The glass lens does not have a flange and thus the prism can be smaller than prisms used in conventional power prisms with the same lens effective area, thus reducing the Z-height of the power prism when compared to conventional power prisms. An optical glass may be used for the lens that has a higher refractive index than can be provided by optical plastic which allows the lens to be thinner than plastic lenses. The lenses may be formed by molding a glass wafer to form lens shapes on a first surface of the wafer; the molded wafer is then ground from a second surface to singulate the lenses.Type: GrantFiled: May 20, 2022Date of Patent: August 29, 2023Assignee: Apple Inc.Inventors: Norimichi Shigemitsu, Kazuya Fujita, Hideki Tanaka, Shuo Wei Huang

Publication number: 20180165174Abstract: The present invention can provide a technology for presenting information that indicates contents and trends of many messages without a need to define a portion that varies among the messages in advance. A message analysis apparatus is provided with a clustering unit, a field analysis unit, and a pattern generation unit. The clustering unit classifies a message set that is an aggregation of messages each being formed of one or more fields, into a cluster, based on similarity among the messages. The field analysis unit identifies, in each of fields that form a message group in the cluster, a variable portion in which a value in the field varies and an invariable portion in which a value in the field does not vary. The pattern generation unit generates a message pattern being common to the message group in the cluster, based on the variable portion and the invariable portion.Type: ApplicationFiled: June 10, 2016Publication date: June 14, 2018Applicants: NEC Corporation, NEC Solution Innovators, Ltd.Inventors: Yasuhiro AJIRO, Shinichi TORIYAMA, Kazuya FUJITA
