Title: Visual field testing method and apparatus
Inventor: MASSENGILL R KEMP
IPC: A61B3/024
Filed: 1997-07-30
Abstract: A method and apparatus are disclosed for using virtual reality for testing and quantifying visual information from the eye, the visual pathways, and the brain. Headgear configuration (12) allows the patient to observe a field of view (7, 11) into which sequenced test stimuli are presented by an excitation device commanded by a computer (13). Interactive sensory (15, 16, 17) feedback both to and from the patient enables computer-driven presentation and modulation of test stimuli to measure with precision such parameters as visual field performance, visual acuity, and color vision. Using the system (5) allows the patient unprecedented freedom of movement of the head and body, thus minimizing or even eliminating the stress and fatigue common with conventional non-virtual reality visual field testing systems.

Title: High speed encoder and encoding method
Inventor: TOWNSHEND BRENT
IPC: H04L5/14
Filed: 1995-12-04
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical, implementation of the system.      The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide-band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Title: 1-aminocyclopropane-1-carboxylate synthase genes from pelargonium and rosa to control ethylene levels in geraniums and roses
Inventor: RANU RAJINDER S
IPC: C12N9/88
Filed: 1997-09-30
Abstract: Genes which encode ACC synthase are identified for the geranium and rose plants, specifically Pelargonium X hortorum cv sincerity and Rosa (cardinal red). These genes are shown as modified to achieve a transgenic plant which resists wilting and the like as a result of reduced ethylene production. This alteration is reproduced by the transformed plant.

Filed: 1999-09-17
Abstract: A connecting unit for making a data connection between first and second data processing installations, which in dependence on an inquiry from a first data processing installation initiates the connection to a second data processing installation for transmission of a data item thereat. The second data processing installation and the data item are identified by the first data processing installation by an address. The connecting unit has an address generator which generates a second address in dependence on the inquiry address and initiates the establishment of the data connection to the data processing installation identified by the second address and the data item. That makes it possible for the nature of the connection to satisfy the particular requirements of the data item being requested, by virtue of the choice of the second address and initiation of connection set-up.
Patent CA-2286490-A1 (CA)
Title: Primer system for agriculture product distribution machines
Inventor: MAYERLE DEAN JAY
IPC: A01M7/00
Filed: 1999-10-29
Abstract: A primer system for agricultural product distribution machines, such as an agricultural air seeder, a precision planter, a sprayer, or the like, includes a tank or a bin for holding the product, a distribution system for conveying and distributing the product from the tank and a driving mechanism for driving the product from the tank into the distribution system at a certain rate. The driving mechanism can run automatically or can be selectively operated, based on commands received from a microcontroller. The microcontroller may receive signals from a user interface and from sensing equipment, such as a ground speed detector, a pressure sensor, a flow metre, or the like. In a regular mode of operation, the controller runs the driving mechanism automatically at a rate calculated based on the signals received from the above mentioned systems. Most agricultural machines have the automated mode of operation of the driving mechanism, conditioned by the ground speed of the tractor being higher than a minimum speed. A bypass mode of operation of the driving mechanism can be selected by pressing a primer button on the user interface. The primer button triggers a bypass signal, instructing the microcontroller to run the driving mechanism at a predetermined dispensing rate, regardless of other factors, such as the detected ground speed. The bypass mode of operation could also be activated upon reception, at the microcontroller, of bypass signals from sensors such as an implement height detector, determining the height of an implement of the agricultural product distribution machine relative to the ground.

Ensuite, la station mobile détermine (6, 11) si elle est en train de recevoir le second VAP. Si c'est le cas, elle annule (7) la première TMSI. La station mobile est alors enregistrée (13) dans le second MSC à l'aide de son numéro d'identification mobile (MIN).

Filed: 1999-12-24
Abstract: A countertop having a laminate or veneer horizontal upper surface and a laminate or veneer vertical face, has a corner element with an arcuate surface that smoothly fairs into both the upper surface and the vertical face. The countertop is made by leaving the vertical edge of the deck unfinished and placing the vertical veneer strip on an edge piece which is then attached to the edge of the deck. The edge piece is made from a block having the vertical veneer strip attached to one of its sides. Diagonal cuts are made at the top and bottom of the face side of the block and rectangularly cross-sectioned strips, from which the corner elements will be formed, are glued to these cuts. The strips are then machined to form the smooth arcuate surfaces which will fair into the laminate surfaces. The back of the block is then machined to create the end piece which mates with the countertop deck.

Title: Device and method for exposing liquids,including pretreated wastewater, to x-rays
Inventor: WEDEKAMP HORST
IPC: C02F1/32
Filed: 1998-09-17
Abstract: The invention relates to a device for exposing liquids to UV-rays, which, seen in the direction of flow, comprises an intake chamber (16), an irradiation chamber (18) and a discharge chamber (20). The irradiation chamber has UV radiation sources (36) which are either aligned in rows and/or stacked parallel to the flow (14). The device is designed as a channel with open top (10), and a containment wall (24) is provided across the direction of flow (14), between the intake chamber and the irradiation chamber. Said containment wall (24) is sized so as to cover part of the channel cross-section, while the lower edge of the containment wall (24) is located at a distance of the channel base (12). The outlet opening (22) thus formed is so sized that, in case of a flow rate increase and starting from a flow rate of 1 m/sec, the liquid accumulates in front of the outlet opening (22), resulting in the liquid level in the intake chamber (16) being higher than in the irradiation chamber (18).
