| Number | Title | Issue Date |
| 5964397 | Passive alignment of components with micromachined tool A method of fabricating an electronic device uses a micromachined tool that has openings which receive and align components with respect to each other and a substrate. The tool has fiducial marks which align to fiducial marks on the substrate, thereby pro... | 10/12/1999 |
| 5249354 | Method of making electronic component packages A method of making a semiconductor integrated circuit package (20) containing a chip (25)--and/or other active or passive electronic component(s)--enclosed in an encapsulation layer (24) can be made thinner by abandoning the limitation of equality of thic... | 10/05/1993 |
| 5230010 | Fractional rate modulation Fractional rate modulation is accomplished by separating incoming data into frames of bits. Each frame is partitioned into bit words of unequal lengths. The words are divided by a modulus to obtain remainders. The remainders are transmitted using for exam... | 07/20/1993 |
| 5187763 | Optical fiber cable having dripless, non-bleeding and optical fiber coating-compatible waterblocking material in core thereof An optical fiber cable (20) includes a core which (22) is filled with a filling material (26) comprising a composition of matter which passes industry wide drip tests, which substantially has no oil separation and which has excellent thermal oxidative sta... | 02/16/1993 |
| 5164983 | Telemarketing complex performance management system A telemarketing complex is managed by a system that compiles and processes traffic analysis data obtained from customer premises-based information sources as well as public switched telecommunications network-based information sources, such that service l... | 11/17/1992 |
| 5155788 | Optical fiber disposed in and decoupled from a reinforcing member A sheathed optical fiber (15) which may be used in a package (20) in guidance systems for tethered vehicles includes a carrier (21) on which are wrapped a plurality of convolutions of the sheathed optical fiber. The sheathed optical fiber in a preferred e... | 10/13/1992 |
| 5081647 | Communication of a voice signal via continuous quadrature amplitude modulator A method and apparatus for communicating a voice conversation over a single telephone channel using continuously variable level quadrature amplitude modulation establishes and maintains two totally independent communication paths, each near perfect in amp... | 01/14/1992 |
| 5054050 | Drop testing in fiber to the home systems Disclosed is a means for testing drop wires in digital loop systems which employ optical fiber up to a distant terminal near the subscriber's premises. A test module is provided at the distant terminal to determine the presence or absence of faults on the... | 10/01/1991 |
| 5032803 | Directional stripline structure and manufacture This disclosure describes a double-sided transmission substrate formed with striplines and end-ports in juxtaposition on either side. The transmission substrate is sandwiched between two exterior dielectric substrates, each coated on one side with a metal... | 07/16/1991 |
| 4904087 | Method for aligning photomasks Photomasks (11, 12) are aligned on opposite sides of a wafer by directing light beams through zone plates (13 A-C) in one photomask and through aligned transparent slits (14 A-C) on the other photomask. Simulantaneous detection of the beams by photodetect... | 02/27/1990 |
| 4899375 | More efficient call handling for operator assistance calls A method and apparatus for processing operator assistance calls with minimum expenditure of operator work time. For collect and person-to-person calls, a first operator at a first operator position determines the type of call and, optionally, the name(s) ... | 02/06/1990 |
| 4884119 | Integrated multiple quantum well photonic and electronic devices In an optoelectronic integrated circuit, an electronic device is integrated with an optical device by fabricating the electronic device directly in a doped semiconductor layer of the optical device. The optical devices contemplated for use include at leas... | 11/28/1989 |
| 4805094 | Multi-channel memory access circuit In many situations, contiguous data is not stored at contiguous locations within a memory. This fact alone causes an increase in processor time for retrieval purposes or the intervention of a memory management unit of some type. The situation is compounde... | 02/14/1989 |
| 4788697 | Method and apparatus for synchronizing a signal to a time base Automatic selection of the rate at which a periodic signal is sampled to obtain a selected number of samples thereof within a predetermined interval is accomplished by first selecting the number of samples to be taken. The periodic signal is then sampled ... | 11/29/1988 |
| 4759039 | Simplified recovery of data signals from quadrature-related carrier signals A technique is presented for simplifying the recovery of two synchronous data signals having a common symbol rate after each signal has respectively modulated a different one of a pair of quadrature-related carrier signals. In the transmitter, the data si... | 07/19/1988 |
| 4747040 | Dual operating system computer The UNIX.RTM. and MS-DOS.RTM. operating systems are supported in a multi-tasking computer. At the heart of the computer is a microprocessor having protected and non-protected modes. The computer includes special-purpose hardware which prevents the MS-DOS ... | 05/24/1988 |
| 4715044 | Automatic synchronous/asynchronous modem There is disclosed an arrangement which enables a single modem port to be used for either synchronous or asynchronous data transmission, with no manual changes required. The modem determines whether the incoming call is synchronous or asynchronous by dete... | 12/22/1987 |
| 4644533 | Packet switch trunk circuit queueing arrangement A trunk circuit interfaces a multichannel data signal to a communication facility using a high priority queue (HPQ) memory, a low priority queue (LPQ) memory, and a data packet sorter including a separate LPQ counter for each data channel. Each LPQ channe... | 02/17/1987 |
