Appl. No.:

09/957312

Inventors:

David Smith - Atlanta GA, US
John Golub - Atlanta GA, US
Fariborz Farhan - Alpharetta GA, US

International Classification:

G02B006/26

US Classification:

385/015000

Abstract:

A multi-wavelength or white-light optical switch including an array of mirrors tiltable about two axes, both to control the switching and to provide variable power transmission through the switch, both for optimization and for power equalization between wavelength channels in a multi-wavelength signal. The output power of a channel is monitored, thereby allowing feedback adjustment of the transmitted power. The mirrors are preferably formed in a micro electromechanics system array to be tiltable in orthogonal directions and having electrostatically controlled tilting by two pairs of electrodes beneath the mirrors. Input power of the separate channels may also be monitored.

US Classification:

725/121000, 725/127000, 370/408000, 359/109000

Abstract:

A communications system includes forward and reverse paths. Reverse path circuitry within an optical node of the system receives reverse analog electrical signals from subscriber equipment and generates therefrom a multiplexed reverse digital optical signal. A coupling node combines digital optical signals and/or RF signals from an optical node or from coaxial cable, respectively. The combined digital optical signal is transmitted over a fiber optic cable to a cable television hub, the reverse path portion of which includes no active circuitry. The hub multiplexes the digital optical signal with other digital optical signals from other nodes to generate one or more forwarded digital optical signals at a hub output, wherein generation of the one or more forwarded digital optical signals requires only passive devices in the reverse path of the hub. The hub is coupled to headend equipment by one or more fiber optic cables, and the headend equipment receives the one or more forwarded digital optical signals and recovers therefrom the reverse analog electrical signals provided by the optical node.

Inventors:

Fariborz M Farhan - Alpharetta GA, US

International Classification:

G08B 25/01

US Classification:

379 38

Abstract:

Microprocessor technology is used to detect routine sounds in a substantially enclosed environment to determine normal or abnormal activity or noise within the environment (i.e., habitual behavior of an individual) A device is situated in a substantially enclosed environment with audio input device similar to a microphone and an optional visual display for interaction with the local users. The device has the ability to be controlled locally via key-pad or USB port connected to a local laptop computer, or remotely via a phone line or Ethernet connection to internet. The device further performs audio pattern recognition using waveform matching scheme to detect the occurrence of pre-programmed sounds representing routine activities. The microprocessor counts the number occurrence of each recognizable sound for a particular interval and over a length of a day or other duration and reports to a remote server. The remote server performs tracking and trending analysis to a web-based caregiver client. Significant changes are detected and reported to caregiver or family web-based client.

International Classification:

A61B 5/00

US Classification:

600300

Abstract:

This embodiment of the invention consists of an apparatus or home appliance unit embodied in a hardware entity running an embedded software program connected to a server computer via a phone line or high-speed internet. At home, the apparatus communicates with an optional set of medical health monitoring devices such as but not limited to, blood pressure monitors, blood glucose meters, and pulse oximeters using wired or wireless communications methods in order to perform wellness measurement. The illustrated embodiments of the invention provide a novel user interface on the home appliance to make the system accessible to people with disabilities. The simple user interface is designed to be accessible to people who are blind or deaf or people who cannot use their hands and require an alternative interface device such as a sip & puff controller. For the hearing impaired, the interface duplicates all speech and informational sounds with text or graphic cues. For the Blind, a Rotary knob provides tactile and audio feedback as the user navigates the system options. As every clockwise or counter-clockwise rotation of the knob brings a new option into focus, the user feels the click of the knob, and hears several audio cues including an audible click, a unique musical chime and a spoken description of the selectable option. For people who cannot use their hands to rotate the knob, alternative input controller devices, (such as a sip & puff controller) are supported through wired (such as but not limited to USB) or wireless (such as but not limited to Bluetooth, Zigbee IEEE 802.15.4, Z-Wave, Wi-Fi) connections. The home unit can further monitor wellness activity of the care recipient by pegging the number of times the care recipient passes by a infra-red motion sensor. The filtering of the latter information and subsequent integration over time and comparison with historical counts per unit of time within a 24 hour period can determine the normal activity pattern for the care recipient over the previous 24 hours.

International Classification:

G05B 23/02

US Classification:

340 31

Abstract:

The use of user equipment, or distracting features thereof are restricted or prohibited to improve vehicle operation safety. The presence of user equipment within the operator's or driver's operational area is detected. The distracting features are then restricted either immediately or based on other conditions such as vehicle speed, motion, engine state, etc. When the conditions have been eliminated and/or the user equipment is vacated from the operator's operational area, the restrictions can be removed or removed after a threshold period of time.

Abstract:

A dark fiber dense wavelength division multiplexing service path design microservice (ddSPDmS) can provide a scalable self-contained meta-data driven approach for a flexible implementation of a dark fiber dense wavelength division multiplexing (DWDM) service path design solution. The service plan design solution can be used as a standalone solution or integrated with a network management application. In order to manage a large volume of circuit designs, multiple microservices can accept application program interface (API) requests in a cloud environment. Permission can then be given to any application to use the API to make a call to the design and inventory. Additionally, metadata templates can be designed to support a node, a link, and/or a topology for the microservices.
