Abstract: A method and system to setup and to manage one or more role-playing game at a single physical location using mobile device is disclosed. The game is distributed and animated on multiple devices connected in real time to a network, preferably to the Internet. Although participants are gathered at the same time and location, each one uses a personal mobile device programmed to provide to the participant instructions and commands relating to the game. To provide instructions, the system comprises a game server configured to provide the game intelligence. The system further comprises mobile devices of each participant connected to the game server during the game play.

Abstract: An improved process for synthesizing acrylic polymers, which is highly controllable to achieve high molecular weight, high conversion rate, and low polydispersity involves continuously introducing initiator(s), acrylic monomer(s), and optionally other monomers capable of polymerizing with the acrylic monomer(s), into a microchannel of a microreactor having an integral micromixer and an integral heat exchanger.

Abstract: The invention provides an RF detection circuit and method using an envelope detector having an output connected to a first input of a differential amplifier and a reference storage capacitor to a second input of the differential amplifier. In a preferred implementation of the calibration mode, there is initial discharging of a reference storage capacitor, high speed charging of the reference storage capacitor until the differential amplifier output toggles, then slower discharging of the reference storage capacitor until the differential amplifier output toggles again. The resulting voltage is stored on the reference storage capacitor for use in a subsequent detection mode. This provides storage of an offset voltage which calibrates both the envelope detector differential amplifier functions.

Abstract: An improved process for oxidation of at least one alcohol group of at least one chemical compound to the corresponding carbonyl group. Said process is carried out in the presence of a buffered oxidative hypohalous solution and of a nitroxide oxidation catalyst. It is characteristically carried out within a micro-reactor; the buffered oxidative hypohalous solution being extemporaneously prepared at a buffered pH comprised between 7 and less than 8.5 (7?pH<8.5).

Abstract: A method for templates for implementing instant message themes is provided. For example, the user selects between a “to-do” theme, an “invite” theme, a “postcard” theme, a “reminder” theme, etc. If the user selects the “to-do” theme, the to-do template may prompt the user to input a description of the task to be performed and a due date/time. An instant message is sent to a recipient who is to perform the task. The recipient's instant message application displays a to-do in a themed IM window. The themed IM window may have special features that are related to the interactions for the to-do theme. For example, the themed IM window can have a “completed indicator” for the recipient to send a completion notice to the sender. Alternatively, the themed IM window could have a button to perform the task. In response to performing the task, the to-do theme could automatically send a completion notice.
