Patent CA-2761889-A1 (CA)
Inventor: ENGELS DANIEL WAYNE
IPC: G06F21/44
Filed: 2010-05-13
Abstract: The present invention describes a system and method for securely identifying and authenticating devices in a symmetric encryption system. An RFID tag can generate indicators using encryption state variables and a symmetric key. An RFID  reader, after receiving the encryption state variables from the tag, may identify the tag by performing an exhaustive key search in a key database. Each key in the database may be tested by using the key and encryption state variables to perform an encryption operation similar to that performed by the tag. The result is then compared with the received tag indicators to determine if the tag has been identified. A rotor-based encryption scheme provides for a low cost key search while providing resilience against cloning, tracking, tampering and replay attacks.

Abstract: Blow down water from an evaporative cooling system, such as a cooling tower, is treated for re-use as cooling make up water. Water in or entering the cooling system is treated with chemicals, for example corrosion inhibitors, scale inhibitors, or biocides. These chemicals are preferably chosen to be compatible with ultrafiltration (UF) and reverse osmosis (RO) membrane systems. Blow down water is removed from the cooling systems and filtered first through a UF membrane unit. The UF membrane unit removes total suspended solids (TSS), microorganisms and organic contaminants, among other things, from the blow down water. Permeate from the UF membrane unit is then filtered through a reverse osmosis (RO) membrane unit to remove, for example, divalent ions and hardness from the water. The RO membrane unit is preferably operated at a high cross flow velocity to reduce fouling. Permeate from the RO system is returned to the cooling system as make up water.

Title: Laser projection clock
Inventor: WANG ERIC
IPC: G04G9/00
Filed: 2012-10-09
Abstract: This invention is of a clock that indicates the time using an array of visible laser lights. The design of the clock consists of three concentric 'medallion-like' sections that are arranged atop one another around a single axis. Like a large button, the unit is activated with a gentle press on the face. The outermost section is stationary and houses a circular array of twelve laser pointers that demarcate the hour indices. The middle and bottom sections both rotate and each houses a single laser pointer that indicates the minute and hour hands respectively. The sides of the three stacked sections taper inwards at an angle to facilitate in directing the lasers down and back towards the surface that the unit is to be placed upon or mounted. The unit is attached to a wall with a magnetic wall mount or can be placed upon a table surface.
