Title: A method and a device for encryption of images
Inventor: JANDEL MAGNUS
IPC: H04N21/4728
Filed: 1999-11-17
Abstract: In a method and a device for partial encryption and progressive transmission of images, a first section of the image file is compressed at reduced quality without decryption, and a second section of the image file is encrypted. Users having access to appropriate decryption keywords can decrypt this second section. The first section together with the decrypted second section can then be viewed as a full quality image. The storage space required for storing the first and section together is essentially the same as the storage space required for storing the unencrypted full quality image. By using the method and device as described herein storage and bandwidth requirements for partially encrypted images is reduced. Furthermore, object based composition and processing of encrypted objects are facilitated, and ROIs can be encrypted. Also, the shape of a ROI can be encrypted and the original object can be decrypted and restored in the compressed domain.

Patent CA-2353156-A1 (CA)
Inventor: MILLER LARRY F
IPC: H01M50/597
Filed: 2001-07-16
Abstract: A device providing reverse polarization protection for a battery having both positive and negative terminals disposed at one end of the battery (e.g., a 9 volt "transistor radio" battery). The device is adapted for insertion between the battery terminals and the spring contacts in a battery housing. The device is made from an electrically insulating material (e.g., plastic), and has at least two openings of unequal size defined through it. The first opening has a diameter larger than that of a negative terminal of the battery, while the second opening has a diameter larger than that of a positive terminal of the battery.  The second opening is sized such that the negative terminal of the battery cannot pass through it, thus providing the required mechanical interference for reverse polarity protection. The thickness of the device is less than the height of the battery terminals. The device is capable of moving freely along the axis defined by the length of the battery in conjunction with spring contact compression/decompression, while being retained within the battery housing.  Since the device is thereby able to move, or "float", the product's spring contacts may be the only compliant components.

Abstract: This invention provides a unique and intellectual parking spot navigating system for urban parking area such as airport, underground parking in urban areas. The system can be used to inform drivers the parking slots status in side the parking area and expedite their parking spots seeking process. The system includes object detection sensors (which are installed at each parking slot in parking area), displaying panels (which collect the information from the sensors and dynamically show the occupancy status of parking slots) and networks (which are wires and cables to connect sensors to the displaying panels). The sensors at each parking spot will detect the occupancy status of a parking slot by detecting the distance of a car inside the slot. The networks that wire the sensors together transfer the sensor signals into displaying panels installed at each level of parking entrances or major intersections. The displaying panel will then dynamically display the occupancy status of all the parking slots in each area.

Title: Rescue holding clamp
Inventor: WALLASCH LUTZ
IPC: B63C9/135
Filed: 2001-08-07
Abstract: A rescue clamp rescues precariously located victims, such as swimmers in water, such as seas, rivers, streams, ponds or swimming pools, climbers in deep ravines, persons on top of a burning building or persons fallen down a well. The rescue clamp includes an orifice clamp into which a victim inserts the hand and forearm. A trigger is activated by being in spring loaded physical contact with a user's forearm or is activated when a trigger handle is grabbed by the victim's hand, to cause the clamp to snugly engage and grip around the victim's wrist or forearm. The rescue clamp grips the wrist or forearm by off-centered hour glass shaped jaws that rotate in unison to reduce the size of the orifice therebetween.

Title: Telomerase reverse transcriptase transcriptional regulatory sequences
Inventor: VASSEROT ALAIN
IPC: A61K35/76
Filed: 2000-02-04
Abstract: Telomerase reverse transcriptase is part of the telomerase complex responsible for maintaining telomere length and increasing the replicative capacity of progenitor cells. Telomerase activity is turned off in mature differentiated cells, but is turned back on again in hyperplastic diseases, including many cancers. This disclosure provides regulatory elements that promote transcription in cells that express telomerase reverse transcriptase (TERT).  Oncolytic viruses are described, in which a toxin or a genetic element essential for viral replication is placed under control of the TERT  promoter. As a result, the virus replicates preferentially in cells expressing TERT, and selectively lyse cancer cells. The viral constructs of this invention hold considerable promise for the treatment of previously intractable malignancies.

Abstract: A process for producing a high moisture cream cheese having desirable textural characteristics (i.e.,increased firmness) is provided. More specifically, the process of the invention provides a high moisture cream cheese with significantly increased firmness by controlling the moisture levels during the manufacturing process at levels below the final target moisture level of the final cream cheese product; the moisture Level of the final composition is then adjusted to the final target moisture level by the addition of water. It has surprisingly been found that control of the moisture levels during the manufacturing process in this manner results in significantly increased levels of firmness in the final cream cheese product. Indeed, the firmness of the high moisture cream cheese product produced using this method is about 5 to about 20 fold greater than standard cream cheese prepared without such moisture control.

Title: Process for removing hydrogen sulfide from gases
Inventor: DEBERRY DAVID W
IPC: B01D53/14
Filed: 2000-02-16
Abstract: The invention provides an improvement to a known process for removing hydrogen sulfide out of a gas, which uses a non-aqueous scrubbing liquor (24) that contains dissolved sulfur and an amine base. The hydrogen sulfide reacts with the elemental sulfur and the amine base to form amine polysulfides and a scrubbed gas (10). The known process uses air to oxidize the amine polysulfides into sulfur, water and amine base, and collects the sulfur (20). The improvement is the use of sulfur dioxide as the oxidizing agent.
