Title: Method and device for strapping individual objects or stacks of objects
Inventor: DE VLAAM HENK
IPC: B65B27/08
Filed: 1998-07-03
Abstract: Objects or stacks (S) conveyed sequentially into a strapping position (U) are strapped in the strapping position (U) selectively with a first strapping or wrapping material (A/A=) parallel to the conveying direction and/or with a second strapping material (B) perpendicular to the conveying direction. For the parallel strapping, the first strapping or wrapping material (A/A=) is positioned across the conveying path of the objects or stacks in the entry of the strapping position (U) and this first strapping or wrapping material is closed and cut behind each object or stack to form a strapping or wrapping, whereby the first material is simultaneously reconnected and repositioned for the next object or stack. Perpendicular strapping is carried out by means of a loop channel (32) arranged substantially perpendicular to the conveying path. For objects or stacks which are not to be strapped parallel to the conveying direction, the first strapping or wrapping material is shifted out of the conveying path.

Title: Method and apparatus for determining the moisture level in a buried splice
Inventor: ESLAMBOLCHI HOSSEIN
IPC: G01R31/02
Filed: 1998-10-29
Abstract: The level of moisture in a buried splice case is provided by a transmitter that is energized from a power circuit via a moisture detector when the moisture detector detects a prescribed level of moisture in the splice case.      Once energized, the transmitter transmits a coded word indicative of the prescribed moisture level for receipt by a receiver located above ground. In this way, a technician, using the receiver can directly determine the moisture level in the buried splice case without the necessity to excavate the case or to contact a member of the On-site Work Force at a communications facility.

Title: Automatic power cut-off device for emergency situations
Inventor: BAE MYUNG SOON
IPC: H01H35/14
Filed: 1999-02-23
Abstract: An automatic power cut-off device for emergency situations which is capable of immediately sensing occurrence of an emergency situation such as an accident of a vehicle striking against an obstacle during its running at a high speed, and automatically cutting off electric power flowing through the vehicle, thereby protecting a driver or other passengers in the vehicle from fire or explosion. The automatic power cut-off device includes an impact sensing device having an impact sensor adapted to sense an impact, thereby generating an impact sensing signal, and a solenoid driving circuit for activating a solenoid in response to the impact sensing signal. A return knob is also provided which rotates between a first position, in which connecting terminals respectively coupled to an electric power source and a load are electrically connected to each other, and a second position, in which the connecting terminals are disconnected from each other. The return knob is maintained in its first position in an inactive state of the solenoid as it is engaged with an engagement extension provided at the solenoid. When the solenoid is activated, the return knob is disengaged from the engagement extension, so that it rotates to its second position by a tension coil spring. Thus, the supply of electric power is cut off.

Title: A method and system of assigning rates based on class service and discount level
Inventor: HASBANI JACQUES E
IPC: G01G19/00
Filed: 1999-03-15
Abstract: The invention is a method and system of assigning and updating rates within an electronic scale, wherein the rates are based upon class service and discount level. A set of classes of service available for a particular carrier is established. Each one of the classes comprises one or more discount levels. The classes are embedded into the memory of an electronic scale and a set of data comprising the classes is made available to the system. Updating of the data in the embedded set of classes, is accomplished by defining the update data and the one or more discount levels which are available in each class. A system user limits the classes for which they want access and the carrier and/or service choices are encoded; the encoding determining a unique number that is indicative of the parameters selected by a system user for a particular system. The unique number comprises: a carrier token; a class token; and a set of discount level bytes representative of the available discount within the class. The unique number is entered through a setup program embedded in the scale and triggers access to services represented by the class. The system uses the newly available data to supersede corresponding data in the embedded set of classes to create a set of new data. An alternative embodiment of the present invention allows linking of the electronic scale with a data center via communication means such as InterNet access.

Abstract: A method and a system for disabling execution of a software application stored within a computer absent data indicative of an authorised use of the software application are disclosed. At start up or during execution of a software application a user is prompted for user authorisation information. Using a processor within a smart card the received user authorisation information is compared with user authorisation information stored in memory of the smart card to produce a comparison result. If the comparison result is indicative of an authorised user of the software application, then data indicative of the authorised use of the software application is provided from the smart card to the computer. Upon receipt of the data indicative of the authorised use of the software application execution of the software application is continued. When the data is not data indicative of the authorised use of the software application further execution of the software application is disabled. For example, biometric information in the form of a fingerprint may be used for user authorisation.
Patent CA-2267484-A1 (CA)
Inventor: BITNER DELOY PEHRSON
IPC: G06F12/02
Filed: 1999-03-30
Abstract: The invention provides a method for removing code (applications and data) from read-only memory, and compacting the remaining code in memory either as an application is deleted or when there is not sufficient room to hold a new application. One or more "spare" memory segments are reserved for use during compaction. Where the code for removal shares a memory segment with other code that is not to be removed, the other code is copied to a spare memory segment, and then swapped back to its original location. The code can then be compacted to remove the "holes" left by the erased code.

Patent CA-2270066-A1 (CA)
Inventor: STEPHENS ROBERT DOUGLAS
IPC: B61L1/06
Filed: 1999-04-19
Abstract: A highly reliable early warning system is disclosed. The warning system provides immediate detection of railway activity and early warning of dangerous railway conditions such as rockfall, to train crews and to Rail Traffic Control offices. The warning system has acoustic sensors coupled to one of the rails of a railway for detecting sound or vibration induced by physical events. The detected acoustic signals are analyzed and if above a threshold, compared to neighboring acoustic detections. If a suspect condition is identified, an alarm is generated. The alarm signal may be transmitted over any communication system to the Rail Traffic Control office and to the trains traveling toward the suspect track location. When desired, the alarm may employ wireless transmissions to stop the trains remotely. When more than one acoustic sensor detects the same event, the exact location can be determined. Physical events that are detected may be stored in a sound file.  These may be catalogued as to location, time and suspected cause for retrieval and analysis later.

Abstract: A processing channel aligned with respect to a continuous, upwardly open transport channel (1) is arranged above the transport channel (1). The transport channel (1) determines together with the processing channel (2) a processing path, along which are arranged successive supply stations (11-17) for supplying the printed material parts (A to G). The processing channel (2) has individual, successive processing zones (3-10) between which are provided passages (18, 19, 119, 20, 120) through which the printed material parts (A to G) located in the processing channel (2) can reach the underlying transport channel (1). The printed material parts (A to G) are opened or deflected to one or another side during their transport between one processing zone to the next processing zone (3-10). Depending on the design of the processing zones (3-10) and on the arrangement of the passages (18, 19, 119, 20, 120), the inner parts (B to G) are arranged in a particular manner in the end printed material (P), either next to or inside one another.
