Appl. No.:

13/549977

Inventors:

David Charles Gregg - San Diego CA, US

Assignee:

CITIZENRE CORPORATION - San Diego CA

International Classification:

G06F 15/00
H04W 80/00

US Classification:

702152, 455 412, 702150

Abstract:

Methods, computer readable media, and apparatuses for providing information about a home, building, or other structure are presented. In certain aspects, a user may interact with a user device in order for the system to determine various characteristics about the structure. In some arrangements, the characteristics may be relevant to solar power installation. For example, a user may interact with an application executing on the user device to provide another computing system with data allowing the computing system to calculate one or more three-dimensional space locations for a characteristic such as roof size or tilt. The characteristic may be calculated as a function of the locations and a known geometric configuration of a sensor unit in communication with the user device.

International Classification:

G06F 17/50
G06F 3/048

US Classification:

703 1

Abstract:

Methods, computer readable media, and apparatuses related to a solar panel layout and installation software tool are presented. In certain aspects, information is retrieved from one or more data sources based on a received location. The retrieved information may correspond to satellite images of the location, climate data for the location, data describing one or more physical structures at the location, and additional information relating to technical or financial considerations of potential solar panel layouts and systems. A user interface may be displayed including a graphical representation of the location and any physical structures at the location, and including a plurality of user options for designing one or more solar panel layouts at the location based on the retrieved information corresponding to the location.

Filed:

May 22, 1989

Appl. No.:

7/355319

Inventors:

David P. Gregg - Culver City CA

Assignee:

Del Mar Avionics - Irvine CA

International Classification:

G11B 2302

US Classification:

369258

Abstract:

The invention is a sealed optical tape cassette. Sealed means is employed to pull optical tape across a mobile recording bridge situated behind a transparent window. Bridge is operated upon by a pair of sealed internal/external pins to control tape tilt, focus and tracking of a light beam from a spinning optical head in a recorder/player to a desired point on the optical tape.

Appl. No.:

5/812158

Inventors:

David P. Gregg - Los Angeles CA

Assignee:

Discovision Associates - Costa Mesa CA

International Classification:

G01D 1510
G11B 700

US Classification:

369275

Abstract:

A transparent record disc is provided which may appropriately have video signals optically recorded thereon, the record is composed of a lamination, for example, of pliant transparent plastic on a base of hard transparent plastic. The base provides strength for the record and the pliant plastic permits the video recording to be impressed into the record by simple embossing means, rather than by stamping or molding by which the surface of the record is actually raised above its melting point and caused to flow. An improved process for forming the video recordings on the disc record is also provided.

Appl. No.:

8/268992

Inventors:

David P. Gregg - Culver City CA

Assignee:

DiscoVision Associates - Irvine CA

International Classification:

G11B 724

US Classification:

369291

Abstract:

An optical tape cartridge is disclosed that is suitable for playing by an optical tape player. The tape player provides the cartridge with a voltage supply capable of supplying the optical tape with a relatively high voltage. The tape cartridge includes a sealed cartridge housing and first and second tape reels that are disposed within and freely rotatable in either direction within the housing. The reels act as tape supply and tape take up reels. Also included in the cartridge is an optical tape that has a first surface on an optically recordable side. The tape is wound on and couples the two reels with a tape segment. The tape segment is positioned with the optically recordable side facing outwardly from each of the reels. The tape includes a conductive layer that extends substantially the length of the optical tape. The conductive layer is grounded at least one end.

International Classification:

G11B 7125

US Classification:

369116

Abstract:

A novel method and apparatus utilizing conventional photo-reactive and reflective layers of a recording medium for optically recording and reading both digital and variable length, analog pulses of data, in an exacting manner to eliminate excess energy absorption by the medium and for reducing latent recording errors due to defects in the recording medium as well as due to the recording process itself. With this precise recording and reading technique, analog variable-length pulse recording, with its inherent wide bandwidth, as well as coded digital pulse recording, with its inherent narrow bandwidth, can be accommodated. The system monitors the optical transmissivity and reflectivity of the recording medium during the recording process in real time to accurately determine initial and terminal inflection points denoting inception and end of a recorded pulse in an exacting manner and to pinpoint and make allowances for recording defects which may yet yield errors on playback. A residual error reduction technique complements the variable pulse recording process by detecting and temporarily storing data and respective address at which data could not be accurately recorded due to chemical or physical anomalies in the recording medium.
