Title: Telecommunications round-robin message delivery
Inventor: GREENSPAN STEVEN LLOYD
IPC: H04L12/58
Filed: 1997-10-08
Abstract: An improved messaging system for transmitting message information to a plurality of recipients comprises the steps of: sending a first message including the predetermined message information to a first recipient address of a first recipient on a list of recipients; updating, after the completion of the step of sending, the list of recipients to create an updated recipient list, the updating being implemented independently of the first recipient at the first recipient address; and sending a second message, including the predetermined message information to an address corresponding to a next recipient selected from the updated recipient list. The method can iteratively repeat the steps of updating and sending the message to thereby transmit messages to a plurality of recipients with the list of recipients being dynamically updated after each message is sent. The recipients may have an opportunity to modify or add to the message before the message is sent on to the next recipient.

Patent CA-2242497-A1 (CA)
Inventor: ZACCARIA ROBERT
IPC: G01R31/36
Filed: 1998-08-19
Abstract: The present invention concerns a battery monitoring system for monitoring a plurality of batteries serially connected to form a string. The battery monitoring system includes a number of probes connected to at least a portion of the string, a daisy chain bus having a select channel for serially interconnecting the probes, the bus having other, parallel channels for data communication and power, and a system server. The probes each have a sensing module and a communication module. The sensing module senses characteristics of at least a portion of the string, such as voltage or current. The communication module receives the sensed characteristics and converts them into digital form for broadcast to the system server over the bus. The communication module of the probes have a memory for storing an address assigned to the corresponding probe upon reception of an initialization signal sent by the system server via the bus.  In order to readdress all of the probes, a reset signal is transmitted to all of the probes. The probes clear the present address, and wait until they are selected through the select channel. Once the probe has been selected, it receives an address from the system server, stores the address in its memory, acknowledges this to the system controller, and sends a signal on the select channel to the next probe. Accordingly, initialization of a battery monitoring system is easily performed. The invention also lies in an interface device for use with a battery monitoring system.

Title: Dry-formed absorbent web material
Inventor: SCHILKOWSKI HELMUT ERWIN
IPC: D04H1/425
Filed: 1997-02-12
Abstract: An inexpensive sheet or web shaped fibre material for use e.g. in sanitary napkins typically consists of a mixture of short cellulose fibres and some 15 % of relatively long, thermoplastic binder fibres. It is a noticeable problem that the short fibres "dust" out of the material, and according to the invention this is remedied in that the material, when made by dry forming, is provided with a surface coating of very thin layers of pure binder fibres. In addition to a marked holding back of the dust, these layers condition that the amount of binder fibres in the base material can be halved and that the breaking stress of the material is noticeably improved. Thereby the products are usable not only as inserts, but also as individual, self-contained units e.g. for wiping in domestic or industrial cleaning.
