Abstract: A semiconductor optical emitting device comprises an at least partially transparent substrate and an active semiconductor structure arranged on a first side of the substrate. A first portion of light generated by the active semiconductor structure is emitted through the substrate from the first side of the substrate to a second side of the substrate along a primary light emission path. The second side of the substrate has a groove formed therein with at least first and second surfaces configured to reflect respective additional portions of the light generated by the active semiconductor structure along respective first and second angled light emission paths. The first and second angled light emission paths may be in opposite directions to one another and substantially perpendicular to the primary light emission path, although numerous other light emission path arrangements are possible.

Abstract: The present invention concerns an apparatus comprising a first module and a second module. The first module may be configured to send a text message over a wireless network in response to one or more user keystrokes. The first module may generate a body of the text message and a security key to be transmitted along with the body of the text message. The second module may be configured to receive the body of the text message and the security key over the wireless network. The second module compares the security key to a set of known security keys to determine a match. A match indicates whether the text message was generated from a known sender. The first and second modules may be implemented as part of a portable device.

Abstract: A set of headphones comprises first and second earpiece assemblies connected by a headband. At least one of the first and second earpiece assemblies comprises a housing, with a rotatable speaker arranged within the housing and configured to rotate independently of the housing about a designated axis of the earpiece assembly responsive to actuation of a control mechanism.
