Patent CA-2444315-A1 (CA)
Inventor: CHATTERJEE AMALENDU
IPC: G08G1/00
Filed: 2003-10-08
Abstract: A parking system for enabling centralized parking reservation, payment and enforcement, comprises a central computer communicating with user terminals and service terminals over a data network. The parking system maintains maps for all parking facilities administered by the respective owner and maintains information regarding the user of the respective vehicle; this information is particularly useful in security sensitive areas. A subscriber may access the system using a wireless or wireline web-enabled terminal, or with the help of an agent, to identify a convenient, un-reserved parking space, reserve that space (advance reservation is available) and pay a fee corresponding to the time the space was used. For subscriber's convenience, payment is cashless, and is tailored to the subscriber's needs; overtime parking protection is also available. The service terminals enable automation of most parking operations. Efficient supervision and enforcement operations of a parking facility are ensured through use of fixed or portable license plate readers (LPR). The parking supervisor/enforcer is provided with the ability to upload into the system the current parking occupancy, download maps with the expected occupancy, and issue parking tickets to offenders. The information on delinquent cars may be sent to the local authority or Department of Motor Vehicles (DMV) to identify repeat offenders for appropriate enforcement in traffic courts.

Title: Molecular characteristics of non-small cell lung cancer
Inventor: NACHT MARIANA
IPC: C12Q1/68
Filed: 2002-08-16
Abstract: We used hierarchical clustering to examine gene expression profiles generate d by serial analysis of gene expression (SAGE) in a total of nine normal lung epithelial cells and non-small cell lung cancers (NSCLC). Separation of norm al and tumor samples, as well as histopathological subtypes, was evident using the 3,921 most abundant transcript tags. This distinction remained when just 115 highly differentially expressed transcript tags were used. Furthermore, these 115 transcript tags clustered into groups that were suggestive of the unique biological and pathological features of the different tissues examine d. Adenocarcinomas were characterized by high-level expression of small airway- associated or immunologically related proteins, while squamous cell carcinom as overexpressed genes involved in cellular detoxification or antioxidation. Th e messages of two p53-regulated genes, p21 WAF I ICIPI and 14-3-3.sigma., were consistently under-expressed in the adenocarcinomas, suggesting that the p53 pathway itself might be compromised in this cancer type. Gene expression observed by SAGE were consistent with the results obtained by quantitative real-time PCR or cDNA array analyses using 43 additional lung tumor and norm al samples. Thus, although derived from only a few tissue libraries, molecular signatures of non-small cell lung cancer derived from SAGE most likely represent an unbiased yet distinctive molecular signature for human lung cancer.

Abstract: The only present method of harnessing the power of gravity for the generation of electricity is by constructing dams and using the gravity-driven force of falling water descending through penstocks to generators in the power plant below.      The Conveyor Belt Generator is a method of harnessing the power of gravity for the generation of electricity and consists of a belt made of steel cables reinforced with iron bars which is thirty feet wide and travels between rotating spindles set three hundred feet apart. Large steel troughs which are mounted at intervals on the conveyor belt are filled with earth and rock or other heavy materials at the top of the belt. Their weight drives the belt and causes the spindles at each end and inbetween the ends to rotate and drive generators connected to them by drive belts. The ballast is dumped out and disposed of at the bottom of the belt.      The Conveyor Belt Generator has three alternative applications.      The first is vertical and is entirely or partially set into the side of a hill whose upper level provides the ballast required for the operation. The second application generates electricity in the same way but here the installation is on the slope of a long hill and the conveyor belt is supported by structural steel towers mounted on masonry piers implanted in the hill. The ballast delivery and discharge systems are the same, but there are modifications to other parts of the installation.      The third application of the system is its vertical installation in the shaft of a decommissioned but serviceable mine, which would take advantage of its underground galleries for the disposal of ballast.

Abstract: The present invention teaches an improved process for preparing a population of microcapsules having a substantially uniform size distribution, especially useful for manufacture of carbonless paper. The improved process teaches use of membrane material having a pre-selected pore size in the capsule manufacture process. A core material is provided along with a receiving solution for receiving the core material. The receiving solution is a nonsolvent for the core material. The core material is passed under pressure through the membrane into a moving or turbulent receiving solution forming uniform droplets of core material dispersed in the receiving solution. Wall-forming material is added to the receiving solution for coating the core material droplets. The coating on the droplets is polymerized forming microcapsules. This novel process also lends itself to microcapsule formation in a continuous process.

Abstract: A highly reflective arrowhead traffic sign is provided which exhibits an arrow shape to "aim" traffic away from a lane. A horizontal longitudinal member has at least one pair of arrow-shaped "wings" that extend beyond the outer boundary of the horizontal member. The wing sets can be attached to the horizontal member by use of locating holes and mating pins, or they can be pivotally mounted on the horizontal member. The arrow wings can be shaped into a configuration that points to the left or to the right, or simultaneously point to both the left and right, thereby indicating to traffic that a lane is closed, and that traffic must go either left or right to avoid the closed lane. The signs can be mounted in different ways, using hooks with suction cups or traffic cones, or using built-in magnets.
