Title: Distributed-feedback laser having enhanced mode selectivity
Inventor: MCCALL SAMUEL L JR
IPC: H01S5/12
Filed: 1987-06-29
Granted: 1990-12-11
Abstract: DISTRIBUTED-FEEDBACK LASER HAVING     ENHANCED MODE SELECTIVITY          Abstract A distributed-feedback laser includes in its grating a localized phase-slip discontinuity which is placed off-center. Such discontinuity results in a quarter-wave phase slip, and it can be placed, e.g., such as to maximize the difference between threshold gain of the lowest-lasing mode and cavity loss of the next-to-lowest-lasing mode. The invention is applicable especially where laser output intensity differs at two output facets and results in enhanced modeselectivity during laser operation.

Title: Residential fuel-oil level reporting and alarm system
Inventor: KNIGHT JOHN D
IPC: H04M11/00
Filed: 1987-09-11
Granted: 1992-04-07
Abstract: RESIDENTIAL FUEL-OIL LEVEL REPORTING AND ALARM SYSTEM     An automatic reorder and alarm system for use with residential fuel-oil tanks which sends reorder and alarm data to a central station over the direct-dial telephone network when the fuel-oil level in the tank falls below a predetermined value or when an alarm situation, such as low temperature, occurs at the tank location.  An inexpensive sensor/sending unit located at each customer tank includes a simple sensor which mounts on either the tank or an existing fuel-oil level gauge, a microcontroller circuit and a modem circuit.  The microcontroller circuit uses a simple low-stability oscillator as a reference for internal operations and for modem transmission frequencies.  Because the oscillator frequency cannot be precisely determined due to component tolerances and has a substantial amount of drift, a special data transmission format is used for data transmission over the telephone lines between the microcontroller and the central station.  The data format consists of a selected pattern of mark and space signals in which each mark signal consists of a predetermined number of cycles of an oscillating signal whose frequency is determined by the internal modem oscillator and each space signal is an equivalent time period without a signal.  At the receiver the bit time duration is determined by averaging bit times in a predetermined bit pattern header.

Title: Auto portrait photo studio
Inventor: LARISH JOHN J
IPC: G03B15/00
Filed: 1987-11-20
Granted: 1991-10-15
Abstract: AUTO-PORTRAIT PHOTO STUDIO            Abstract of the Disclosure A method and system (including a unique arrangement of computer and photographic apparatus) for automated or computer-aided portrait photography.  The method and system utilize an automatic, between-the-lens 35mm camera including auto-wind, auto-focus and auto-exposure features.  A beam splitter behind the camera lens captures a part of the image-forming light reflected from the portrait subject to provide a video pickup charge coupled device with an exact color video image of the subject as seen by the camera.  On the outside of the camera housing a flat screen video viewfinder is provided which permits the operator (portrait photo-grapher) to view the image which is being received by the video pickup device.  The camera and overall system components are interfaced with and connected to a microprocessor and are controlled by the flash circuitry of the camera.  When the operator is satisfied with the subject's appearance and pose (as seen through the video viewfinder), press-button action trips the camera shutter for exposure of a frame of film, actuates the flash circuitry of the camera firing flash lighting apparatus and directs (through the microprocessor) the electronic storage (via solid state memory) of a video image identical to the image captured by the camera film.  The stored video image can be outputed to a video portrait viewer (CRT screen) for subject viewing.  The portrait viewer can also be utilized to display a multiplicity of the capture (stored) video images (each representing a film frame) for subject selection.

Granted: 1993-08-10
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to articles for cleaning, buffing, conditioning, or restoring surfaces.          Abrasive articles made from nonwoven fibers have long been used for cleaning floors and other surfaces. Although previously known nonwoven abrasive articles are extremely useful for the purposes for which they are intended, they rapidly lose their efficiency as they become saturated with dirt.          This invention provides an abrasive article comprising an open, lofty nonwoven web comprising helically crimped synthetic organic fibers.  The article can optionally contain stuffer box crimped fibers and melt bondable fibers.          The presence of helically crimped fibers brings about greater durability and greater capacity for absorbing debris.
