US Patent:

6603808, Aug 5, 2003

Filed:

Jul 22, 1999

Appl. No.:

09/359018

Inventors:

Ramakrishna Anne - Spring TX
Robert F. Watts - Houston TX

Assignee:

Compaq Information Technologies Group, L.P. - Houston TX

International Classification:

H04B 138

US Classification:

375222, 709200

Abstract:

A networking modem capable of full duplex communication over a telephone line is adapted for use as a component of a computer system. The modem comprises a digital signal processor (DSP) capable of implementing a plurality of digital modulation and demodulation techniques, including pulse position modulation (PPM), quadrature phase shift keying (QPSK), and quadrature amplitude modulation (QAM). The DSP implements a digital phase locked loop (DPLL), including a carrier NCO and a carrier detector to synchronize local demodulation timing to an incoming carrier signal. Available processing options include spectral agility for optimizing channel capacity, symbol shaping to compensate for evolving channel conditions, and echo cancellation. The digital processing provides a flexible, adaptive, programmable, and backward compatible solution to eliminate various problems with prior art systems, including timing inaccuracies, incompatibility with standard modulation techniques, the half duplex limitation, and the susceptibility to noise that increases intersymbol interference and limits throughput.

US Patent:

62826603, Aug 28, 2001

Filed:

Oct 1, 1998

Appl. No.:

9/164543

Inventors:

Ramakrishna Anne - Spring TX
Robert F. Watts - Houston TX

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

G06F 126

US Classification:

713300

Abstract:

A computer's representation and handling of dial-up and network applications are standardized. A LAN connection is established on a session basis only when required, enabling a user or system administrator to have the same control over the LAN connection as is typically exercised over a WAN connection. Examples of WAN connection features that are available to the LAN connection are the maintenance of billing information, access control, authentication and verification. In addition, an application can be represented by several different icons configured to utilize different procedures and communication devices.

Filed:

Feb 4, 1998

Appl. No.:

9/018692

Inventors:

Benjamin H. Skinker - Spring TX
Robert F. Watts - Houston TX
Paul E. Nagel - Draper UT

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

H04B 138

US Classification:

375222

Abstract:

A modem which is separated into two circuit boards. One board contains the modem engine, while the second board contains the codec and the DAA components. The two boards are connected using only properly isolated digital signals so that the modem engine board does not require certification, only the codec/DAA board requiring certification. The codec/DAA board is contained in a housing to provide proper high voltage protection.

International Classification:

H01M 1044
H01M 1046

US Classification:

320 5

Abstract:

A computer system including circuitry for accurately and economically controlling the charge voltage and charge current at the terminals of its rechargeable battery. During a battery recharge, sensor circuitry coupled to the battery provides accurate data to a battery microcontroller regarding the charge voltage and charge current present at the battery terminals. A battery microcontroller relays this information to a multipurpose microcontroller. The battery microcontroller also provides the desired charging voltage and current as determined by the battery pack's charging algorithm. The multipurpose microcontroller uses the battery status information to program an addressable potentiometer. In turn, the potentiometer generates an adjustment signal that controls the output voltage of the computer's AC adapter. Preferably, the AC adapter is capable of being operated in a constant-power mode.

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

G10L 900

US Classification:

704258

Abstract:

An audio circuit for a computer includes a bidirectional modem connection, a microphone input, first and second audio output channels, and an audio synthesizing circuit arranged to produce first and second synthesized audio channels. In a first mode of operation the first synthesized audio channel is applied to the first audio output channel and the second synthesized audio channel is applied to the second audio output channel. In a second mode of operation the first and second synthesized audio channels are combined into a monotonic signal and applied to the second audio output channel, and audio signals from the bidirectional modem connection are applied to the first audio output channel.

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

H04M 1100

US Classification:

379 9328

Abstract:

A combination x digital subscriber line (xDSL) and analog modem including a computer bus interface, codecs, an analog front end (AFE) for xDSL communications coupled to a plain old telephone service (POTS) line and a direct access arrangement (DAA) for analog communications also coupled to the POTS line. The modem is designed on a peripheral component interconnect (PCI) card. Generally,. +-. 12, 5 and 3. 3 volts are available for PCI components. Traditionally, the AFEs for non-PCI modems were designed to operate on. +-. 12 volts for differential POTS line driving. For differential POTS line driving, the AFE typically requires a regulated voltage. However,. +-. 12 volts supplied to PCI cards are typically not as well regulated as the 5 and 3. 3 volts, and therefore the. +-. 12 volts is generally unsuitable for PCI modem AFE design.

International Classification:

H04M 156

US Classification:

379142

Abstract:

A reduced number of relays are used in a voice/data/fax modem system. This reduced relay design eliminates at least one relay required in prior art systems thereby reducing the amount of geography used in producing the resultant device. This saves space, reduces costs, and provides a more reliable device.
