Patent CA-2199990-A1 (CA)
Inventor: PETERS WOLFGANG
IPC: H04N7/16
Filed: 1997-03-13
Abstract: For transmitting video data via an integrated services digital network (NET), there are first transmitted request signals from a video telephone (TEL2) to a server (SER), and the selected video data are subsequently transmitted to the video telephone (TEL2) over a switched connection in real time. The server (SER) comprises an encoding unit (K) with two encoders (K1, K2). The first encoder (K1) is provided for encoding video data of a sequence of video images. The second encoder (K2) is provided for encoding selected separate frames which are encoded with a higher resolution than the sequence of video images. The encoding method can be selected repeatedly through request signals without interrupting the switched connection, whereafter either a sequence of video images or a still image is transmitted to the video telephone (TEL2). The still image can, for example, be stored or printed out via facsimile equipment.

Patent CA-2212062-A1 (CA)
Inventor: HENRICKSON MARK J
IPC: F04D13/06
Filed: 1997-08-29
Abstract: When a disaster occurs Emergency Response Teams are reliant on available sources of water from conventional hydrant systems, which during a disaster are typically compromised. They also use stationary pumping systems which may not be located within the vicinity of the fire or conventional portable pumps which are very inefficient in delivering volumes of water. In this invention a rapid deployment jet drive type centrifugal pump is floated on a body of liquid (i.e. water) by means of a hull to provide an emergency and/or alternate source of water to fight fires. The power source for the pump is either attached to the pump and floated in the same hull or remotely located providing power to the pump by means of an umbilical. The jet drive type centrifugal pump is utilized solely for pumping liquids.

Patent CA-2214330-A1 (CA)
Inventor: CHUN MICHAEL KAI-WAH
IPC: A47B21/03
Filed: 1997-10-17
Abstract: When using a computer keyboard, or a computer cursor display control device known as a mouse, the shoulder, elbow, and wrist can become tense and uncomfortable as a result of strained muscle. To prevent such cases, a tool generally known as a wrist rest is used to support the hand Different wrist rests are used for keyboards and mice. In this invention, unlike prior art wrist rests which all have a flat base, a shorter member with a convex base and a top surface covered with suitable material such as neoprene etc., and having straight sides is used. Two separate devices are preferred for supporting the two hands. One device can be used as a wrist support for using a mouse. If desired, two or more of this device can be connected together to form a longer device. The convex base enables the flat top surface of the device to conform automatically, by tilting backward or forward as the hands work, to the changing angle of the hand. The tilting action can be steadied by placing the side of the device against the side of the keyboard or mouse pad if desired. Unlike the prior art desk pads, the mobile wrist support device can be used with keyboards and mice of any size and shape. Its shorter length allows it to be carried easily in laptop computer cases.
