Title: Beam scan velocity modulation apparatus with disabling circuit
Inventor: ANDERSON MARK ROBERT
IPC: H04N3/32
Filed: 1991-07-25
Granted: 1995-12-26
Abstract: In a television receiver, employing both a beam scan velocity modulation (SVM) system and an on screen display (OSD) generator, the OSD generator selectively operates to produce characters or graphics which are superimposed on the main video picture display. During operation of the OSD generator, the SVM circuit may tend to undesirably introduce artifacts into the picture display. Circuitry is provided for selectively disabling normal SVM circuit operation during OSD operation to prevent or reduce the perception of such artifacts.

Title: Method and apparatus for processing fish heads
Inventor: SIGURDSSON ARNI MATTHIAS
IPC: A22C25/14
Filed: 1992-04-29
Granted: 2003-02-25
Abstract: A method and apparatus for cutting tongues, cheeks and belly flaps from fish heads and for cutting apart jaws of fish heads. The fish head is mounted on a reinforced beam beneath a spiked chain which moves the head along the beam, first towards horizontal knives which cut the tongue from the head, and then to vertical knives which cut the cheeks and the belly flaps from the head. Over the tongue knives are jaw rods which hold the jaw up to the beam adjacent the tongue knives. Inside the beam is a stick which can be driven down from the beam to locate the tongue in a cutting position below the tongue knives. The head hits a sensor which activates a power source for the stick. The belly flaps are held up by belly flap rods, which lie beneath the collar bones and keep the belly flaps from the tongue knives. The cheeks and belly flaps are cut off with two vertical cheek knives. Behind the cheek knives, there is a vertical step on the belly flap rods which support the belly flaps while the knives cut the cheeks and belly flaps. The jaw is then cut apart with a jaw knife located on the beam. One of the jaws then falls down a sliding chute which moves the head up and off the beam and then falls into a vat for bones.

Title: Reduced time remote access method and system
Inventor: COOPER CHRISTOPHE KAY
IPC: H04M11/06
Filed: 1991-11-14
Granted: 1999-09-07
Abstract: Several techniques for reducing the amount of time between initiation of a terminal request through a dial-up telephone line and the actual initiation of transactions between the terminal (10) and a host computer (32). By using a ring down or hotline circuit configuration, dialing and call setup time can be saved. With the ring down use no login procedure is necessary to ensure secure access to the host computer (32). The ring generation period is shortened to just an interval sufficient to allow the host modem (30) to recognize the ring, with the ring indication period also being shortened. The modems (12, 30) can be set to fixed baud rates, but in a more preferred embodiment the terminal modem (12) transmits the orginate carrier prior to the host modem (30) picking up the line. The host modem (30) then senses the originate carrier quickly and provides the answer carrier. The silent interval prior to operation of the host modem (30) is removed. After the carriers are both provided, normal connection to the host computer (32) is made and the transaction completed.
Patent CA-2098480-C (CA)
Inventor: STRIPF HELMUT
IPC: G01N29/38
Filed: 1991-12-12
Granted: 2003-02-11
Abstract: A delay time measurement method for ultrasound of the type wherein a testing head transmits an excitation pulse that is as close as possible to the shape of a shock wave and traverses a pretravel path until it reaches the object to be examined which has a front wall and a rear wall, with at least one reflected pulse being generated at its front wall as well as at its rear wall. To improve the above-mentioned type method so that delay time measurements for thickness determinations and abnormalities can be performed reliably even on rough surfaces and if reflected pulses are missing or falsified, a time window is determined for the recording of reflected pulses that follow the excitation pulse, within which window all successive reflected pulses are digitized. Then the reflected pulses that lie within the time window are digitally filtered and parametrized, and the filtered and parametrized reflected pulses are fed to a computer unit and are evaluated on the basis of variable criteria using a predetermined algorithm.

Title: Method and system for digital image signatures
Inventor: POWELL ROBERT D
IPC: G06T1/00
Filed: 1993-07-30
Granted: 2005-08-23
Abstract: A method and system for embedding signatures within visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, the signature persisting through image transforms that include resizing as well as conversion to print or film and back to digital form. Signature points are selected from among the pixels of an original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount detectable by a digital scanner. The adjusted signature points form a digital signature which is stored for future identification of subject images derived from the image. In one embodiment, a signature is embedded within an image by locating relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema. Preferably, the signature is redundantly embedded in the image such that any of the redundant representations can be used to identify the signature. Identification of a subject image includes ensuring that the subject image is normalized with respect to the original image or the signed image.  Preferably, the normalized subject image is compared with the stored digital signature.
