Title: Secure distribution of digital representations
Inventor: SAITO MAKATO
IPC: H04L29/06
Filed: 1999-02-09
Abstract: Techniques for secure distribution of digital representations that combine encryption and watermarking. When a user at a client desires to download a digital representation, the user makes a request to a server for the digital representation, which encrypts the digital representation using a first key and downloads the encrypted digital representation to the user. Before the user performs any operation on the decrypted digital representation, a secret fingerprint watermark identifying the user is added to the digital representation. The fingerprint watermark is added either at the server or at the client and a copy of the fingerprinted digital representation is kept at the server. If the user makes an impermissible use of the digital representation, the secret fingerprint watermark can be used to identify the user. The request made by the user indicates the type of use that the user whished to make of the digital representation. If the use involves storage of the digital representation at the client, the server provides a second key that the client employs to encrypt the digital representation. If the user has permission to do so, the user may modify the digital representation and return the modified digital representation to the server for further distribution. In this case, the second key is used to encrypt the digital representation when it is sent to the server. The second key also serves as the user identification in the fingerprint watermark. If the user loses the second key, it can be recovered from the copy of the fingerprinted digital representation kept at the server. The first and second keys and any decrypted copy of the digital representation are kept in secure storage in the client.
Patent CA-2319674-A1 (CA)
Inventor: QUINN DESMOND
IPC: E21B43/08
Filed: 2000-10-03
Abstract: A sand sleeve and method of use of the same. The sand sleeve has a tubular body with a plug seat at a second end to accommodate a removable plug and shiftable sleeve at a first end that can be shifted to an open position to permit fluid flow, while the removable plug is in place. The sand sleeve is inserted into a well with the shiftable sleeve in a closed position and the tubular body in an orientation where a first end is above a second end. The shiftable sleeve is shifted to the open position with the removable plug engaged with the plug seat. This permits entry of oil and gas into the well from a formation through the radial flow openings, while the removable plug prevents fluids from lower formations from flowing through the central flow channel and intermingling. Flow turbulence through the radial flow openings keeps sand from settling on the removable plug.

Title: Cutting device of an agricultural harvesting machine
Inventor: UROS RAYMOND
IPC: A01F15/10
Filed: 2000-10-20
Abstract: A baler for making large cylindrical bales is equipped with a cutting device for cutting picked up crop into pieces before it enters the baling chamber. The cutting device includes a plurality of cutting knives that are pivotable about a horizontal transverse axis between an working position for cutting crop, wherein the knives each project upwardly through respective slits provided in a guide sheet, and a non-working position wherein the knives are withdrawn to a non-working position substantially below the guide sheet. A  plurality of knife positioning elements are respectively associated with the knives and mounted for pivoting about a second horizontal transverse axis such that when the positioning elements are in a first position corresponding to the working position of the knives rollers respectively carried by the positioning elements are in engagement with a recess in a surface provided on the rear of the associated knife. The positioning elements are biased such that the roller carried by a given positioning element will remain in the recess of the associated knife so long as the force tending to rock the knife to its non-working position is below a predetermined amount. Once this force is exceeded, the knife will pivot to its non-working position until the force once again falls below the predetermined amount. A sensing device is associated with a warning or indicator circuit for letting the operator know when one of the knives has moved to a position not occupied by the remaining knives.

Title: Method and apparatus for controlling a laser-equipped machine tool to prevent self-burning
Inventor: SCOTT WILLIAM B
IPC: B23K26/38
Filed: 2001-02-19
Abstract: A control system is provided for a laser-equipped machine tool which is capable of preventing self-burning. The temperature of the workpiece proximate the cut is monitored, and a numerical control compares the actual workpiece temperature to a prestored temperature limit, empirically determined, which is predictive of the onset of self-burning. If the workpiece temperature approaches or reaches the limit, an abort signal is generated. Upon generation of an abort signal the control processor deenergizes the laser to prevent commencement of self-burning. In addition the processor stores the cutting parameters and the coordinate locations of the aborted cut, so that the processor can later return to finish the cut, and sets a cool-down timer. The processor then causes movement to a next available cutting position, tests the temperature at that position, then commences cutting. When cutting in the second location is complete, if a cool-down timer has expired, the cutting head is traversed to the aborted position, and then the processor retrieves stored information and completes the cut.

Patent CA-2342614-A1 (CA)
Title: Control system for bathers
Inventor: CLINE DAVID J
IPC: H02H3/33
Filed: 1999-08-31
Abstract: A control system for bathers includes an electronic controller which controls operation of an electric heater assembly connected in a water flow path for heating water. The heater assembly includes a heater housing and electric heater element. A solid state water temperature sensor apparatus provides electrical temperature signals to the controller indicative of water temperature at separated first and second locations on or within the heater housing. The presence of water in the heater housing is detected electronically, by turning on the heater, and monitoring the temperature sensors for unusual temperature rises or other faults for a period of time thereafter.      A solid state water presence sensor apparatus can also be used to determine the presence of water within the heater housing, providing electrical water presence signals to the controller indicative of the presence or absence of a body of water within the heater housing. An independent circuit apparatus is connected to the water temperature sensor apparatus and to a power relay, automatically causing high voltage power to be disconnected from the heater assembly when the water temperature exceeds a predetermined temperature. The independent circuit apparatus requiring a manual reset once the water temperature has dropped below a predtermined level to allow the high voltage power to be reconnected to the heater assembly. The system includes ground continuity detection, ground current detection and ground fault detection circuits.
