Title: Remote telemetry and control using asynchronous messaging
Inventor: TANG VICTOR W
IPC: H04L12/24
Filed: 2000-03-15
Abstract: The present invention relates to a system of communicating data between a remote device and a Central Processing Station. It defines how a remote site or device, be it fixed or mobile, is coupled with an apparatus that can collect and send data regarding the host and/or receive and respond to instructions sent by a Central Processing Station. It describes how the method of communication is through an asynchronous means, whereby the apparatus does not require a direct connection, handshaking protocol, or any immediate response from the Central Processing Station. This asynchronous connection, notably through the Internet electronic mail standard, is what distinguishes this system from other patents. The system also teaches the methodology whereby the Central Processing Station processes and responds to messages received from the remote devices. Finally, it defines the interaction of the end-user with the remote device, which is solely through requests made through the Central Processing Station, reports prepared and messages forwarded from that same station. The party monitoring or controlling the remote device (the end-user) does not have any direct interaction with the device - all interactions are made through the Central Processing Station

Patent CA-2320069-A1 (CA)
Inventor: LINDBERG LINA
IPC: B65D25/28
Filed: 1999-02-12
Abstract: The invention is related to a device in a container of the type basket for merchandise or customer's basket for providing a handle or grip, which is properly designed from an ergonomic point of view. The handle or grip design, which is common today, requires the lifting hand to have to be rotated into an unnatural angle. If the lifting hand would assume the natural angle at rest, a long side of the basket will be turned forwardly in the walking direction. The invention solves this by orientating the grip or handle (2) with its longitudinal direction substantially parallel to a long side of the basket whereas at the same time the attachment (3, 4) of the handle to the basket along one long side provides for a maximum amount of availability for handling merchandise present in the basket.

Patent CA-2323745-A1 (CA)
Title: Identification system using predetermined interval strobed signals
Inventor: HELLER ALAN C
IPC: G06K7/00
Filed: 1999-01-26
Abstract: An identification system is implemented according to the invention in which the identification data of a wireless transmitter is divided into multiple bursts (154, 156, 158, 160, and 162). Instead of transmitting the entire identification in a single burst, the identification is split among bursts, so that it takes a period of time to uniquely identify a particular transmitter.  However, the time between bursts (tA1, tA2, tA3, tA4, and tA5) falls under tight tolerance, so that once a transmitter is identified, it can be further identified based on when it transmits as opposed to what it transmits. In this way, high tractability can be maintained without repeatedly transmitting the entire identification code of the transmitter.
