Title: Jumper tracing system
Inventor: LEONARD GEORGE COHEN
IPC: G02B6/24
Filed: 1995-12-19
Granted: 1996-06-11
Abstract: The present invention includes a system for tracing jumpers used in an exchange to cross-connect optical fibers or wires served by the exchange. The system includes an exchange housing receptacles with optically-encoded data associated with each receptacle or a group of receptacles. The optically-encoded data for a receptacle(s) uniquely identifies the physical location of the receptacle from any other receptacle in the exchange. Also, this optically-encoded data can include the type of jumper and/or length of the jumperto be used with the receptacle, the correct routing of the jumper through the exchange, the traffic to be carried on the jumperand/or the identity of the physical location of the receptacle to be connected to the other end of the jumper. Likewise, the jumpers each have optically-encoded data formed thereon that uniquelyidentifies the jumper or jumper end and distinguishes the jumper from any other jumper used in the exchange. The optically-encoded data associated with the jumper can include the type of jumper, the length of the jumper, the proper routing of the jumper through the exchange and/or the traffic to be carried on the jumper. If nojumper is to be connected to a particular receptacle, a cover with optically-encoded data can be attached to a receptacle to indicate that no jumper is connected to the receptacle. The system of this invention also includes a hand-held optical scanner that can be used by an operator to scan the optically-encoded data associated with a receptacle(s) and the optically-encoded data of a jumper(s) connected to the receptacle(s), and transmits the optically-encoded data signals to a computer of the sysem of this invention. The computer can generate a display of the physical location of a receptacle(s) in association with the identity of the jumper(s) and connected thereto, so that an operator can diagnose misconnections of the jumpers between receptacles in the exchange. Further, the computer can store verification data that can be compared with optically-encoded data signals from scanning with the optical scanner, to determine whether the proper jumper has been connected to a receptacle, whether the jumper is of appropriate type or length for the cross-connection and whether the jumper or receptacle is associated with traffic that is of interest to the operator, for example.

Title: Digital communications modulation method and apparatus
Inventor: NELDON P JOHNSON
IPC: H04J99/00
Filed: 1996-04-30
Granted: 1997-03-01
Abstract: A method and apparatus for single signal, multiple channel digital information transfer through waves with time slot allocation. The apparatus consists of one or more transmitting devices and one or more receiving devices. Multiple source signals are each allocated a unique time slot between successive synchronization waves. Digital signals from each source are converted to analog information waves having a positive wave segment and a negative wave segment. The ratio of the amplitude of the positive wave segment to the amplitude of the negative wave segment, the positive-to-negative ratio, for each signal source, is a function of the magnitude of the source digital. The sum of the amplitude of the positive wave segment and the absolute value of the amplitude of the negative wave segment, the positive-to-negative offset, is maintained at a pre-set value at transmission. The total signal, which consists of successive synchronization waves interspersed with information waves for each signal source, each within its allocated time slot, is transmitted to the receivers which extract the positive-to-negative ratio and positive-to-negative offset for each signal source, calibrate the received signals and generate output signals which reproduce the transmitted inputs.

Abstract: A method for directly assembling window on the scene, its steps are: - Install and fix several reinforced fixing frames that can assemble into specific shape on model board; - Cover pad that has same shape with specific frame on circumference of specific frame that is formed by several frames, then install window-frame that has same shape with circumference of specific frame on pad, then cover same shaped pad; - Fix several reinforced fixing frames on another model board that is closed to above model board; - Pour concrete in between two model boards. Due to the space in between window frames is isolated with outside, therefore, the concrete can not get into the space, and when concrete is solidified, the window frame will fix in the wall. Then take out model boards, pads and reinforced fixing frames to assemble the window on window frame.

Title: A method for fabricating semiconductor component
Inventor: YOU TSUEI-RUNG
IPC: H01L21/70
Filed: 1997-03-31
Granted: 1999-07-11
Abstract: A method for fabricating capacitor of DRAM is disclosed. It comprises the steps of depositing a doped polysilicon layer, defining said doped polysilicon layer to delimit the lower electrode range of said DRAM capacitor, and depositing a hemispheric-grained silicon (HSG-Si) layer on the surface of said doped polysilicon layer. A thin non-crystalline silicon layer is formed on top of said HSG-Si layer, said complicated polysilicon structure forms the lower electrode of said DRAM capacitor. A dieletric layer is formed on top of said lower electrode, and a second polysilicon layer forms an upper electrode. HSG-Si dies just formed are susceptible to form sharp junction on the polycide layer on which they grow. When HSG-Si dies are exposed to a thermally oxidizing atmosphere, the sharp junctions of HSG-Si dies and the doped polysilicon layer are prone to form low-quality oxide which might lead to the breakdown of lower electrode of capacitor or electricity leak. By growing a thin non-crystalline silicon layer on HSG-Si surface, the sharp junction of HSG-SI and polysilicon layer can be dulled, therefore providing more reliable capacitance with thermal oxide layers or other dielectric layers subsequently formed.
