Patent CA-2180752-A1 (CA)
Inventor: PETERS WOLFGANG
IPC: H04W4/00
Filed: 1996-07-08
Abstract: To provide an interactive video service, a system is disclosed comprising a video server (VOD), an integrated services digital network (ISDN), and customer premises equipment (END) with a video telephone (TEL). The video server (VOD) has a memory (MEMO) in which a number of video films, e.g., newscasts, are stored, as well as a transmitting unit (SEN) and a receiving unit (EMP), by means of which it is connected with the video telephone (TEL) via the integrated services digital network (ISDN). Via the video telephone (TEL), the customer calls the video server (VOD) to establish a switched connection, and selects from among a number of video films available. By means of a control unit (CTRL) in the video server (VOD), the selected video film is read from the memory of the video server and transmitted in real time over the switched connection to the video telephone (TEL). The customer can release the connection at any time, whereby the transmission of the video film is stoppped.

Title: Container adapted for spraying
Inventor: GARTNER PETER
IPC: B05B11/00
Filed: 1996-08-23
Abstract: The invention relates to a container such as a bottle or can made from sheet metal, plastic or any desired material, which is adapted for spraying. The container has a spray valve disposed on the top side, and a pumping attached to the bottom side of the container for generating excess air pressure in the container. The pumping device is connected with the interior space of the container via a first valve. The pumping device consists of two bellows tightly connected to the bottom side of the container and concentrically placed one inside the other. The inner bellows is tightly inserted in the outer bellows, which is designed as a bottom cap. A second valve is inserted in a bottom opening of the inner bellows. The container functions in such a way that lifting the container allows air to enter the inner bellows via the second valve. The second valve is configured so that air is not permitted to escape out of the inner bellows through the valve. Depressing the container against a support forces the air in the inner bellows through the first valve and into the interior space of the container.

Inventor: PATHAK VINAY K
IPC: A61K35/76
Filed: 1995-05-16
Abstract: The present invention provides retroviral vectors comprising direct repeats flanking a sequence that is desired to be deleted upon reverse transcription in a host cell. In a preferred embodiment the sequence that is desired to be deleted is the retroviral cis-acting encapsidation sequence (E) essential for virus production in helper cells. in gene therapy embodiments, the E sequence is deleted upon reverse transcription in target cells, thus preventing spread of retroviral vectors to non-target cells in the event of infection with replication competent viruses. The retroviral vectors of the present invention thus provide safe vectors for gene therapy.

Title: Position sensing controller and method for generating control signals
Inventor: REDFORD PETER M
IPC: G06F3/033
Filed: 1995-07-24
Abstract: An improved position sensing controller (40) allows a person to precisely control the movement of a remote object or device in one or two dimensions by simply tilting the hand-held controller (40) to generating control signals. A position sensor (48a) that includes a bubble (56) in a liquid is used to determine the angular position of the controller with respect to a horizontally level plane. A light source (64) emits light that is reflected by the bubble, into two opposing photodiodes (68a, 68b). A ratiometric amplifier (80) produces a signal corresponding to the ratio of the light incident on each of the photodiodes (68a, 68b) to provide a signal corresponding to the angle, relative to a horizontally level plane, by which the controller is tilted. The controller (40) can use a diffused laser light-emitting diode to transmit signals to the controlled device.
