Patent CA-2207986-A1 (CA)
Inventor: REESINK MARTIN
IPC: A61F9/02
Filed: 1997-06-27
Abstract: This invention, "Screenies", may be classified as straddling two sectors of the economy: computer hardware and labour safety. Its computer hardare component is that physically, Screenies is a pair of protective, preventive eyeglasses or spectacles with a magnetic coating or mechanism or lense.     The eyeglasses's purpose brings Screenies into the labour safety sector of the economy, because it is worn to protect computer users's retinal tissue, optic nerves and other ophtamological tissue from extremely and very low frequency radiation (ELF and VLF) emanating from computer screens or monitors, or Video Display Terminals (VDTs). The very low radiation is measured between 2kHz to 400kHz and ELF (extremely low frequency) ranges from 5Hz to 2kHz. But VDTs also produce radiation in the 15 to 18,000 Hz, which is harmful to brain and bone tissue, and human eyesight.     Ten years ago, the Swedish National Board for Measurement and Testing proposed a set of safety standards known as MPR which are now widely accepted in the US and Europe for labour safety standards. Screenies is an invention that in the future will provide protection from all VDT's, as these monitors become increasingly pervasive. The latest technological development focusing on the eye's uniqueness and commercial utility is a bank machine that identifies users from their retinal print, as opposed to the current punched-in number or letter code. Hence, bank machines screens, video games, computers, televisions, are all VDTs which increasinlgy and pervasively will radiate more lethal radiation to the eye, to the optic nerve and perhaps to the brain. Screenies will therefore become increasingly important to protect users from the inadvertent and often invasive intrusions made by commercial and entertainment VDTs. Another manner in which to portray the important commercial, health and safety scope of Screenies is to compare their utility, ingenuity and novelty to the automobile seatbeat. Sixty years ago, when automobiles were invented, the primary concern was rapid surface movement at relative low cost. Safety was a secondary concern. Extend the parallel: today, rapid, low-cost identification and communication exchanges between consumer and service provider is the primary concern for a multitude of transactions with secondary concern for long term molecular, biological and pathalogical effects of VDT radiation on the human eye. Screenies therefore provide the same effective, versatile and personalized blanket protection from ever-pervasive and inadequately identified radiation as do seatbelts.

Title: User mode proxy of kernel mode operations in a computer operating system
Inventor: SHAW GEORGE H J
IPC: G06F9/46
Filed: 1997-06-19
Abstract: This invention involves user mode proxy of kernel mode operations in a computer operating system. The broad contours of the invention allow drivers operating in the kernel mode of an operating system to be proxied by a corresponding user mode object. A user mode process wishing to communicate with or manipulate the kernel mode driver may perform such communication or manipulation by communicating with or manipulating the corresponding user mode proxy. The present invention has particular applicability to emerging operating systems which allow kernel mode drivers to be interconnected in order to create a processing stream in the kernel where data is passed from kernel mode driver to kernel mode driver without transitioning to user mode. User mode proxy of such kernel mode drivers allows user mode processes to manipulate such kernel mode drivers using familiar user mode protocols without the necessity of learning new kernel mode protocols.

Title: Bidding for telecommunications traffic
Inventor: JOHNSON JACK J
IPC: H04Q3/58
Filed: 1996-10-31
Abstract: Telecommunication switches (e.g., PBX's or local exchange carrier's switches) route calls in accordance with economic icentives (e.g., least cost routing) resulting from a bidding process between participating interexchange telecommunication carriers (Carriers) by operation of a central processor, a computer referred to as a bidding moderator (Moderator). Each of the Carriers informs (28) the Moderator of the rate it is willing to charge (or other economic incentive it is willing to offer) for service between two specific points in the telecommunication network at some particular time. The Moderator collects this bid information (20) from all the Carriers, sorts it among originating points (22) and transmits (23) it to an adjunct processor at each subscribing switch location and to all participating Carriers' network management centers (21). From the list of all Carriers providing bid information to the Moderator, each Subscriber can select those Carriers to which it wants traffic routed and can change that selection at any time. After each new bid is submitted (28) by a Carrier and is processed by the Moderator (22), it is distributed to both the relevant Subscribers (23) and all other Carriers (21). All Carriers have the opportunity to submit (27, 28) at any time a lower or higher bid for any point-to-point routes on which they wish, respectively, to stimulate or discourage additional traffic. The Moderator could offer a different class of service to end users who are calling parties by broadcasting each carrier's bid to an interface unit at each user location.

Title: Portable/potable water recovery and dispensing apparatus
Inventor: LEBLEU TERRY LYLE
IPC: C02F1/32
Filed: 1997-04-05
Abstract: A portable, potable water generator for producing high-purity liquid water by condensation of dew from ambient air is described.      The generator employs filtration subsystems (38) to remove particulates and aerosols from the incoming air. An enclosed heat absorber (22) cools the filtered air below its dew point and collects (25) droplets of condensate into a closed system (26). The collected liquid dew is further continually treated in a bacteriostat loop (29, 31) to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are failsafe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.      Hybrid embodiments of the water generator attached to or integrated with refrigeration-type appliances such as water coolers, refrigerators, freezers, icemakers and air-conditioners are illustrated.
