Title: A method of manufacturing a twisting cylinder display using multiple chromatic values
Inventor: SHERIDON NICHOLAS K
IPC: G02B26/02
Filed: 1998-09-30
Abstract: An electric type paper display having memory properties, rapid response times and multi-optical property display with an image of high quality is made. Each display element is wholly in contact with liquid in a cavity and the surface of each display element has a portion with a most positive charge. When an electrical field is applied from the outside, each display element is turned correspondingly to the direction of the electric field and, then electrically migrated through the liquid and attached to the inner surface of the cavity. Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e., its display state is held by the action of an attraction force such as van der Waals force and electrostatic force acting between the circumferential surface of the display element and the inner surface of the cavity, even after the electric field is removed.

Patent CA-2257259-A1 (CA)
Title: Method and apparatus of preserving power of a remote unit in a dispatch system
Inventor: LEKVEN ERIC J
IPC: H04B1/16
Filed: 1997-06-06
Abstract: To reduce the power consumption of a remote unit in a dispatch system the remote unit enters a dormant state. A base station (32) transmits a forward link broadcast signal and monitors a common access channel. A first remote unit (10) continually receives and decodes the forward link broadcast signal and determines whether said forward link broadcast signal comprises active signals (106). If the remote unit determines that the forward link broadcast signal comprises no active signals for some a duration T1, the first remote unit enters a dormant mode (148). In the dormant mode the remote unit sporadically receives and decodes said forward link broadcast signal. If this remote unit or any other remote unit on the same net presses a push to talk button (128, 130), it transmits a message on the common access channel. In response, every remote unit on the net which is in a dormant state exits the dormant state and continually monitors the forward link broadcast signal.

Abstract: An electrical connector provides for the connection of the contact pads of an IC card to conductive elements of a printed circuit board. The connector includes a base supportable on the printed circuit board and at least one elastomeric element assembled within the base and aligned with upper and lower surfaces thereof. The base provides at least one retention tooth from which an IC card is easily withdrawn using a blunt implement, thereby obviating the need for a separate cover to retain the card in the device. The base also provides two additional fingers which bias inward against a side of a card and transversely apply forces on the card in order to annul the width differences among different cards. The elastomeric element is fabricated from a polymer which facilitates electrical interconnection between the element and the contacts on the SIM card. The elastomeric element replaces metal contacts which are widely utilized in conventional IC card readers. However, tine same holder can accommodate metal contacts for those manufacturers not yet employing elastomeric contact technology.

IPC: G01M3/24
Filed: 1997-10-21
Abstract: When an underground pipe carrying a fluid, such as a buried water-pipe, develops a leak the leak must first be located before it can be repaired. One common location method makes use of the fact that the leaking fluid often creates a noise, typically a hissing sound, which is transmitted through the ground, and although rapidly attenuated can be heard with suitable highly sensitive ground microphones and is therefore useful to field crews as a means of locating leaks. Unfortunately, the sound levels can be grossly distorted by underground heterogenities, and can easily be confused or even swamped by other sound sources above ground, and in general ground microphones used like this do not seem to be effective. The invention deals with the problems entailed in this technique by a method - and apparatus - which involves using semi-automated equipment to listen (either simultaneously or sequentially) to the leak sound source (1) from a multiplicity of different positions (as 3) spaced all around the sound source, and by then suitably combining and processing the received signals to provide the desired indication of the source's location.

Abstract: The present invention is directed to systems and methods for synthesizing a three-dimensional video stream from a two-dimensional video source. A frame (48) from the two-dimensional video source is digitized (50) and split (54) into a plurality of fields (56, 58). Each field contains a portion of the information in the frame. The fields are then separately processed and transformed (60, 62) to introduce visual clues that, when assembled with the other fields, will be interpreted by a viewer as a three-dimensional image. Such transformations can include, but are not limited to, skewing transformation, shifting transformations, and scaling transformations. The transformations may be performed in the horizontal dimension, the vertical dimension, or a combination of both. In many embodiments the transformation and reassembly of the transformed fields is performed within a single frame so that no temporal shifting is introduced or utilized to create the synthesized three-dimensional video stream. After the three-dimensional video stream has been synthesized, it is displayed on an appropriate display device. Appropriate display devices include a multiplexed display device which alternates the viewing of different fields in conjunction with a pair of shuttered glasses which allows one field to be displayed to one eye of viewer and another field to be displayed to another eye of a viewer. Other types of single display devices and multidisplay devices may also be used.
