Patent CA-2355739-A1 (CA)
Inventor: EBNER EMANUEL C JR
IPC: A47K5/12
Filed: 1999-12-23
Abstract: An automatic soap dispenser (10) includes a disposable soap container including a dispensing mechanism (20) in which walls of an interior chamber (56) cooperate with a diaphragm (62) and a plunger (66) to form a transit chamber (64), which is resiliently expandable against the force of a spring (80). When a solenoid (58) permits the diaphragm (62) to move away from the outlet of a passage (50) in a flow path from the interior of a pressurized reservoir (18) to the expandable transit chamber (64), travel of the plunger  (66) permits the transit chamber (64)'s pressure-relieving outlet opening to  expand so that the pressure within the transit chamber (64) is determined predominantly by the force of the spring (80) rather than by the pressure within the reservoir (18). The velocity of the liquid dispensed from the transit chamber (64) through the dispensing mechanism's spout (16) is therefore relatively independent of the pressure within the reservoir (18).< /SDOAB>

Title: Safe trigger with time delay for pneumatic fastener driving tools
Inventor: ROBINSON JAMES W
IPC: B25C7/00
Filed: 2001-12-11
Abstract: A pneumatic fastener-driving tool is disclosed wherein not only rapid-fire bump-firing or trigger-firing modes of operation are permitted wherein either one of the trigger member and workpiece contact element components can be depressed before the other one of the trigger member and workpiece contact element components depending upon the particular mode of operation that the operator personnel chooses to employ, however, the tool is also rendered safe for transportation by operator personnel between job sites or work sites in view of the fact that if the workpiece contact element is not depressed, as a result of not being disposed in contact or engagement with a workpiece, within a predetermined period of time subsequent to the performance of the last fastener discharge or firing operation, then the tool is pneumatically disabled and can only be again enabled if the proper sequential activation of the tool is performed wherein the workpiece contact element must be engaged with a workpiece prior to the depression or activation of the tool trigger. Accordingly, after the expiration or lapse of the aforenoted predetermined period of time, should the operator personnel carry or transport the tool with the trigger member nevertheless depressed, the tool will not fire or discharge a fastener even if the workpiece contact element is depressed due to the fact that the tool has already been pneumatically disabled.

Patent CA-2371417-A1 (CA)
Title: Laser welding components to an optical micro-bench
Inventor: MUSK ROBERT W
IPC: G02B6/36
Filed: 2002-02-11
Abstract: Many optical components now use a microelectronic substrate called an optical micro-bench as a base from which to build. Conventional devices use one or more methods of fixing the various elements together and/or onto the semiconductor micro-bench.  Typically these conventional methods require special coatings to be deposited on the substrate, and the use of a separate bonding material, e.g. solder, glass or adhesive. The present invention relates to the direct fixation of a semiconductor, e.g. silicon, indium phosphide or gallium arsenide, structural component to the micro-bench made of a similar material using a laser welding technique, which uses wavelengths that are not harmful to the other elements of the component.  The present invention eliminates the use of any separate bonding material, as well as several steps in the bonding process.

Title: Tamper resistant software encoding
Inventor: GU YUAN
IPC: G06F9/44
Filed: 2000-06-08
Abstract: The present invention relates generally to computer software, and more specifically, to a method and system of making computer software resistant t o tampering and reverse-engineering. "Tampering" occurs when an attacker makes  unauthorized changes to a computer software program such as overcoming password access, copy protection or timeout algorithms. Broadly speaking, th e method of the invention is to increase the tamper-resistance and obscurity o f computer software code by transforming the data flow of the computer softwar e so that the observable operation is dissociated from the intent of the original software code. This way, the attacker can not understand and decode  the data flow by observing the execution of the code. A number of techniques  for performing the invention are given, including encoding software argument s using polynomials, prime number residues, converting variables to new sets o f boolean variables, and defining variables on a new n-dimensional vector spac e.
