Patent CA-2016444-C (CA)
Title: Luminance signal/color signal separating circuit and noise reduction circuit using a comb filter
Inventor: MIKI SHIGERU
IPC: H03H15/00
Filed: 1990-05-10
Granted: 1995-05-23
Abstract: A luminance signal/color signal separating circuit comprises a comb filter for Y/C separation.  The addition output of the comb filter comprises a luminace signal component, while the subtraction output comprises a color signal component and non-correlation components of a luminace signal.  The non-correlation components in the subtraction output are extracted by a trap circuit and added to the addition output of the comb filter.          Accordingly, the degradation of vertical direction resolution of reproduced signal will be prevented.  Also, under some circumstances, the extracted non-correlation components are previously enhanced before being added to the luminace signal.  The noise reduction circuit in reproduction mode shares the above comb filter for color signal separation.  When dropout occurs, the color signal in the output of the 1H delay circuit of the comb filter is inverted and separated to be used as a drop out compensation signal.

Title: Digital signal hardware protection switching
Inventor: ENG STEPHEN KA-YEE
IPC: H04L69/40
Filed: 1992-11-24
Granted: 1999-01-12
Abstract: Protection switching of digital signal transmitting and receiving hardware is realized in a "hitless" manner. The hitless switch is obtained by employing hardware switching units which can individually determine the instant to switch from an active state to a standby state and vice versa. A switch is initialized by supplying a switch request signal from a control unit to a hardware switching unit in the active state. The active hardware switching unit, upon detecting a prescribed bit condition, for example, a predetermined bit state, of the digital signal being supplied as an output therefrom, supplies a predetermined synchronization pulse to the standby hardware switching unit. In response to the synchronization pulse, the standby hardware switching unit forces the bit condition of a bit of the digital signal to be supplied as an output therefrom resulting from a current input bit to be in the same bit condition as that detected in the active hardware unit. Output circuits in both the active hardware switching unit and standby hardware switching unit are simultaneously turned OFF and ON, respectively, in the individual units by observing the digital signal being supplied as an input to both units. Upon detection of a predetermined bit condition of the input digital signal individually by each of the hardware switching units, the active unit output circuit is turned OFF and the standby unit output circuit is turned ON at the same instant. The instant of turning OFF and On of the output circuits is determined individually in each hardware switching unit. (FIG. 5)

Title: Methode et appareil de transmission d'informations
Inventor: BLOW KEITH JAMES
IPC: H04B10/2507
Filed: 1991-09-03
Granted: 1997-11-11
Abstract: Un système de communication optique comporte un laser (10) commandé de façon à produire une chaîne d'impulsions solitoniques (12) transmise à un groupe diviseur de faisceaux (14, 20, 22) qui convertit cette chaîne d'impulsions (12) en une chaîne d'impulsions (24) ayant une fréquence d'impulsion double.  La chaîne d'impulsions (24) est modulée de façon à former un signal codé binaire par le modulateur (24), lequel produit une suite de chiffres binaires ayant chacun l'une des deux valeurs dans laquelle une suite de n impulsions solitoniques lumineuses, où n est un entier  1, est transmise à une fibre optique (4) et des répéteurs (6) servent de liaison de transmission à un récepteur (8).  La présente invention permet d'accroître la puissance moyenne dans un bit sans avoir à utiliser des impulsions plus brèves, ce qui serait nécessaire avec une densité d'une impulsion solitonique par bit comme dans les systèmes actuels afin d'éviter les limitations inhérentes à ces systèmes.  Le résultat est que la limite du bruit est transposée à des impulsions plus longues ce qui permet d'utiliser des débits binaires plus élevés même s'il y a un plus grand nombre de solitons dans chaque bit d'information qu'avec les méthodes de modulation à un soliton par bit.  La méthode réduit également le sautillement et élargit par conséquent la gamme de fonctionnement en transposant la limite à des impulsions plus longues.

Abstract: Nitric oxide, nitrosoni-nm, S-nitrosothiols, and S-nitroso-proteins can be de-tested in biological samples, using a method which in-volves injection of samples into a photolysis cell, prior to detection of chemilumines-cence generated by the reac-tion between nitric oxide and see Formula I ozone. To detect S-nitrosoth-iols and S-nitroso-proteins separate aliquots of the same samples are subjected to pre-treatment with mercurous ion, and a protein-precipitat-ing agent, respectively, and the resulting nitric oxide sig-nals are compared to those generated by untreated sam-ples. This method is useful for monitoring the levels of nitric oxide bioactivity in both normal physiological states, and diesease states, such as septic shock, atherosclerosis, thrombosis, hyperhomocysteinemia, pulmonary hypertension, malignancy, infections and central nervous systems disorders.
