  • Patent number: 6871214
    Abstract: A notification system is coupled to a plurality of message services including a voice mail server, an email server and an information server in an office. Messages left for a user (e.g. voice mail, email, CRM event, etc.) are deposited in folders maintained by the messaging services. The notification system detects additions to the user's folders and when a new message arrives, the notification system sends an alert to a Wireless Access Protocol (WAP) enabled device (e.g. cell phone) configured for the user. The alert includes the total number of messages of each type received for the user, along with an indication of the most recently received message. The notification system may further monitor an information source for new information that may be of interest to the user (e.g. stock or product price quotes), and provide these in the alert notification if certain conditions are met (e.g. stock price exceeds a threshold).

  • Patent number: 6748003
    Abstract: A VCSEL having improved diffraction loss; comprising a series of deposited material layers comprising the structure of the VCSEL, and an intracavity lens formed in one of the series of deposited material layers. In one preferred form of the invention, the VCSEL comprises a bottom mirror mounted to the top of a substrate; a bottom spacer mounted to the top of the bottom mirror; a gain region mounted to the top of the bottom spacer; a top spacer mounted to the top of the gain region; and a top mirror mounted to the top of the top spacer, such that a reflective cavity is formed between the bottom mirror and the top mirror; with at least one of the bottom mirror, bottom spacer, gain region, top spacer and top mirror containing a superlattice structure, and with an adjacent region being subjected to ion implantation and rapid thermal annealing so as to disorder the superlattice structure and change its index of refraction, whereby to create an intracavity lens so as to reduce diffraction loss.
