Abstract:
The invention relates to lithium metal/porous metal oxide compositions. These lithium metal compositions are prepared by mixing liquid lithium metal with a porous metal oxide in an inert atmosphere under exothermic conditions sufficient to absorb the liquid lithium metal into the porous metal oxide pores. The lithium metal/porous metal oxide compositions of the invention are preferably loaded with lithium metal up to about 40% by weight, with about 20% to 40% by weight being the most preferred loading. The invention also relates to lithium reagent-porous metal oxide compositions having RLi absorbed into a porous oxide. In formula RLi, R is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkaryl group, or an NR1R2 group; R1 is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkaryl group; and R2 is hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, and an alkaryl group. The preparation and use of these compositions are also described.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller adapted to establish communications with a voicemail system over a Public Switched Telephone Network port of the communication device, receive from the voicemail system by way of a broadband port of the communication device an invitation to switch to a video call over the broadband port, transmit a Session Initiation Protocol message to establish video communications with the voicemail system, and transmit to the voicemail system a video message to be recorded by the voicemail system as a video voicemail message. Additional embodiments are disclosed.
Abstract:
The invention relates to a method for removing an alkyl sulfonyl or aryl sulfonyl protecting group from a primary or secondary amine by contacting an alkyl sulfonamide or an aryl sulfonamide with a Stage 0 or Stage I alkali metal-silica gel material in the presence of a solid proton source under conditions sufficient to form the corresponding amine. The invention also relates to a method for removing an alkyl sulfonyl or aryl sulfonyl protecting group from a primary or secondary amine by a) reacting an alkyl sulfonamide or an aryl sulfonamide with a Stage 0 or Stage I alkali metal-silica gel material, and b) subsequently reacting the reaction product from step a) with an electrophile or a proton source. Preferred Stage 0 or Stage I alkali metal-silica gel materials include Na, K2Na, and Na2K.
Abstract:
A method and system for managing messages in a unified messaging (UM) platform to enable message recall is disclosed. The UM platform deposits a message from a sender into a UM mailbox of a recipient. It is then determined whether the sender of the message is a UM subscriber. If the sender is a UM subscriber, a copy of the message or a link to the message is deposited into a UM mailbox of the sender. The UM platform then provides a message recall option with the copy of the message or the link to the message in the UM mailbox of the sender. If the sender is not a UM subscriber, a recall message including a randomly generated message recall URL is sent to the sender. This allows the sender to select the randomly generated message recall URL to send a message recall request to the UM platform, which deletes the message from the mailbox of the recipient in response to the message recall request.
Abstract:
A scanning projector includes a mirror that scans in two dimensions. The scanning mirror oscillates at a resonant frequency on a fast-scan axis, and is phase locked to an incoming frame rate on a slow-scan axis. An interpolation component interpolates pixel intensity data from adjacent pixels based on the position of the mirror when a pixel clock arrives. Incoming video data is stored in a buffer. Less than a complete frame of video data may be stored in the buffer.
Abstract:
Methods and apparatus to perform call screening in a voice over Internet protocol (VoIP) network are disclosed. An example method comprises sending a call initiation request to a VoIP endpoint, receiving a call screening indication from a user of the VoIP endpoint in response to the call initiation request and prior to a no answer determination made by an initiating call server, and playing a message for the user while a calling party is leaving the message.
Abstract:
Methods and apparatus to route emergency communication sessions are disclosed. An example method involves querying a gateway node cache in response to a first broadcast probe received at a node of a wireless Internet-based network. When the gateway node cache identifies a first gateway node, a first response is selectively sent to nodes that participated in a search flood associated with the first broadcast probe.
Abstract:
A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.
Abstract:
Methods and apparatus to route fax calls in an Internet protocol (IP) multimedia subsystem (IMS) network are disclosed. An example method comprises receiving a message including a called party number and a media description at an IMS network and determining if the media description is associated with a fax protocol. Additionally, when the media description is associated with a fax protocol, the example method attempts to locate a fax-specific uniform resource identifier (URI) associated with the called party number.
Abstract:
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for managing transcription resources. A system practicing the method retrieves a class of service for a subscriber recipient of a message deposited at a first server for transcription by a second server, determines a probability of near-term access of the message by the subscriber, assigns a weight to the message based on the class of service and the probability of the near-term access, and transcribes, at the second server, the message based on the weight. Classes of service can include a real-time class of service and/or one or more non-real-time class of service. The probability of near-term access can be based on subscriber presence, subscriber receipt of a new message notification, historical statistics of subscriber message access times, message urgency, and other message metadata. A channel manager can manage a finite number of channels between the first and second servers.
