Abstract: Exemplary methods for enabling the scheduling of a meeting activity between a service professional and a customer are described. A service professional is prompted to select a type of meeting activity from multiple meeting activities. The service professional is further prompted to enter structured information related to the meeting activity. The quotes including the meeting activity information are received from each service professional and transmitted to the potential customer. The customer is then enabled to accept the meeting activity, and provide additional information for the meeting activity. The potential customer is further enabled to modify one or more details of the meeting activity and transmit a response to the service professional. When the service professional and the potential customer agree on the meeting activity information, a notification message is transmitted to each one of the service professional and the potential customer including all details of the meeting activity.

Abstract: This invention relates to an assay label comprising an amorphous carbon particle, a functionalised dextran polymer attached to the surface of the carbon particle and a first member of a complementary binding pair covalently bonded to the functionalised dextran polymer. The invention also provides a device incorporating the assay label, which further comprises a radiation source adapted to generate a series of pulses of electromagnetic radiation at a wavelength such that the absorption of the radiation by the label generates energy by non-radiative decay; a sample chamber containing a transducer having a pyroelectric or piezoelectric element and electrodes which is capable of transducing energy generated by non-radiative decay into an electrical signal; and a detector which is capable of detecting the electrical signal generated by the transducer.

Abstract: A method and apparatus for delivering a message to a caller prior to the moment the recipient unhooks or answers their telephone or other network interface device, as well as optionally delivering a message to the caller, the recipient, or both after the connection between the service provider and the caller, and/or the connection between the service provider and the recipient has been established. The method and apparatus are effective for use with all telecommunications systems, including, but not limited to, optical-based telephone systems, wire-based telephone systems, wireless telephone systems, optical-based computer network systems, wire-based computer network systems, wireless computer network systems, and heterogeneous network systems.

Abstract: This invention relates to a device (1) for detecting energy generated by non-radiative decay generated in a substance (2) on irradiation with electromagnetic radiation. The device (1) comprises a radiation source (6) adapted to generate a series of pulses of electromagnetic radiation, a transducer (3) having a pyroelectric or piezoelectric element and electrodes (4, 5) which is capable of transducing the energy generated by the substance (2) into an electrical signal, and a detector (7) which is capable of detecting the electrical signal generated by the transducer (3). The detector (7) is adapted to determine the time delay between each pulse of electromagnetic radiation from the radiation source (6) and the generation of the electric signal. The device (1) has a wide applicability in the fields of assays and monitoring.

Abstract: A multiple effect evaporator system and a process for concentrating a process liquid wherein evaporated process liquid from one effect serves as heating fluid in an adjacent effect. Low energy heating fluid in vapor form is fed to an evaporative surface condenser where it is condensed and collected as clean and foul condensate. Coolant for the evaporative surface condenser is provided in the form of process liquid from one of the effects. Prior to passage into the evaporative surface condenser, the process liquid is cooled. In the cooling circuit of the evaporative surface condenser, the process liquid absorbs the heat of condensation of the heating fluid and subsequently rejects the heat into a counter flowing air stream. The process liquid is thereafter heated and returned to another of the multiple evaporator effects.
