An archival system is formed from one or more carriers (10) or the loose or detachable pages (14, 16) of one or more carriers (10) when completed and positioned in a ring-type binder or other suitable binder or folder with one or more interleaved indexing sheets. The indexing sheets are to separate completed carriers (10) or pages (14, 16) by subject matter or topic. Each carrier (10) has one or more pages (14) of a first type fixed to a spine (18) formed along one side of the carrier (10). One or more pages (16) of a second type are provided. The or each page (14) of the first type are pre-printed with introductory statements and/or notations intended to be completed by the sender, and the or each page (16) of the second type having provision to receive and hold one or more photographs, press cuttings or other items of record about or of interest to the intended receiver of the carrier.
摘要:
A method and system is provided for gathering and packetizing data from networked building automation equipment, and for transmitting data packets as instant messages to remotely located users. An instant messaging (IM) server-based system is provided to facilitate communication between networked building equipment and a remotely located service contractor. When a registered router is operated, the router establishes a continuous pass-through communication link with the IM server and with building equipment connected to the router. The router automatically polls connected building equipment for alarms, faults and system failures, and also receives, processes, and responds to user requests for specific data from particular items of building equipment. Data gathered by the router is packetized, and the packets are then encapsulated into an instant message that is transmitted to the IM server. Authorized users who log on to the IM server are then provided access to the instant message containing the packetized data. Additionally, remote users can solicit gathering of data by the router by submitting to an IM server an instant message requesting the router to gather and return specific data from particular item of building equipment.
